METHODS, EU, AND BASE STATION FOR UPWARD TRANSMISSION WITHOUT DYNAMIC CONCESSION
TECHNICAL FIELD [001] The present disclosure refers to systems and methods for configuring resources of a wireless communication system.
BACKGROUND [002] In some wireless communication systems, user equipment (UE) communicates wirelessly with a base station to send data to the base station and / or receive data from the base station. Wireless communication from a UE to a base station is referred to as uplink communication. Wireless communication from a base station to a UE is referred to as downlink communication.
[003] Resources are needed to perform uplink and downlink communications. For example, a UE can transmit data wirelessly to a base station on an uplink transmission at a specific frequency and / or during a specific interval in time. The frequency and time interval used are examples of resources.
[004] In some wireless communication systems, if a UE wants to transmit data to a base station, the UE requests uplink resources from the base station. The base station grants the uplink resources, and then the UE sends the uplink transmission using the granted uplink resources. An example of uplink resources that can be provided by the base station is a set of
Petition 870190116979, of 11/13/2019, p. 8/100
2/87 frequency-time in a multiple access frame by orthogonal uplink frequency division (OFDMA).
[005] The base station is aware of the identity of the UE that sends the uplink transmission using the uplink resources granted, because the base station specifically granted those uplink resources to that UE. However, there may be schemes in which the base station does not know which UE, if any, and when to send an uplink transmission using certain uplink resources. An example is a uplink transmission scheme without concession, in which UEs can send uplink transmissions using certain uplink resources shared by the UEs, without specifically requesting the use of resources and without receiving resources dynamically by the base station. The base station, therefore, will not know which UE, if any, and when to send an uplink transmission without concession using the pre-configured resources. Multiple terminologies can be used to mean the same as transmission without concession, such as random access without concession, without concession, transmission of configured concession, transmission of preconfigured concession, autonomous transmission (preconfigured), transmission (UL) without concession (dynamic ) and semi-persistent scheduling (SPS), etc.
SUMMARY [006] A method and apparatus for configuring resources for transmission without concession are provided.
[007] In one embodiment, a first UE receives a first RRC signal from a base station. The first RRC signal specifies a first subset of parameters

3/87 configuration for transmission without concession to the first UE. The first UE can also receive a first DCI signal from the base station. The first DCI signal can specify a second subset of the configuration parameters for transmission without concession to the first UE. The second UE receives a second RRC signal from the base station. The second RRC signal can specify one or more configuration parameters for transmission without concession.
[008] In some modalities, the first subset of the configuration parameters specified by the first RRC signal may comprise the periodicity of the resource for transmission without concession. The second subset of the configuration parameters specified by the first DCI signal can include one or more UL time / frequency resources reserved for transmission without concession, a modulation and coding scheme (MCS) parameter for transmission without concession, and a reference signal demodulation (DMRS) for transmission without concession.
[009] In some embodiments, the first UE can perform a first transmission without concession according to the configuration parameters for transmission without concession on the first RRC signal and the first DCI signal. Optionally, in one embodiment, the first UE can perform the first UL transmission without concession, according to the first subset of configuration parameters for transmission without concession specified in the first RRC signal and the second subset of configuration parameters for transmission without specified concession at the first DCI signal.

[0013] In some embodiments, the second UE performs a second UL transmission without concession, according to the configuration parameters for transmission without concession specified by the second RRC signal.

[0015] Optionally, in some modalities, for configuration based on non-DCI signaling, a UE can receive updates of configuration parameters on an RRC signal or a DCI signal from the base station. For example, the second UE may receive a third RRC signal comprising information to update one or more configuration parameters for transmission without concession specified by the second RRC signal. In another example, the second UE can receive a second DCI signal specifying information to update one or more configuration parameters for transmission without concession specified by the second RRC signal. After receiving the updates, the second UE can perform a UL transmission without a concession, according to one or more configuration parameters updated for transmission without a concession.
[0016] Optionally, in a modality, a UE can use the configuration parameters for transmission without concession to perform data transmission without concession or control of message transmission without concession. For example, the first UE can perform the first UL transmission without concession, according to the first and the second subset of configuration parameters for transmission without concession, and the first UL transmission without concession can be data transmission, message transmission. control or a combination of both. In another example, the first UE can perform the second UL transmission without concession, according to the one or more configuration parameters for transmission without concession specified by the second signal.

8/87 time feature for transmission without concession, a modulation and coding scheme (MCS) parameter for transmission without concession, a demodulation reference signal configuration (DMRS) for transmission without concession, power control parameters and a or more repetition factors for transmission without concession. The first UE can then perform a UL transmission according to one or more configuration parameters for transmission without concession specified by the multiplexed broadcast signal.
[0019] Optionally, in a modality, when in an inactive or idle state, the second UE can receive a broadcast signal specifying one or more configuration parameters for transmission without granting the base station.

The base station can also transmit a first DCI signal to the first UE. The first DCI signal can specify a second subset of the first UE configuration parameters. The base station transmits a second RRC signal to a second UE. The second RRC signal specifies one or more second UE configuration parameters.

Mini-gap terminology can also be referred to as non-gap. The TTI here is also applicable to the transmission of any uplink (UL) and / or downlink (DL) control information.
[0025] In some modalities, the base station receives, from the second UE, a second UL transmission without concession, according to the configuration parameters for transmission without concession in the second RRC signal. In one embodiment, DCI signaling is not necessary for configuring resources for the second UE. Thus, with the second RRC transmitted, the base station can receive, from the second UE, the second UL transmission without concession without waiting for the transmission of a DCI signal to the second UE.
[0026] Optionally, in some modalities, at least one of the first and second RRC signals can comprise information indicating one of at least two predefined resource configuration options for UL transmission without concession. The first default transmission resource configuration option can be a combination of dynamic signaling downlink control (DCI) information and non-DCI signaling (for example, RRC signaling). The first RRC signal transmitted by the base station may indicate that the first UE is receiving a combination of RRC configuration and DCI / Layer 1 signaling configuration.

12/87 non-DCI signaling (for example, RRC signaling). The second RRC signal transmitted by the base station may indicate that the second UE is receiving a configuration based on non-DCI signaling.
[0027] Optionally, in some modalities, for the configuration based on non-DCI signaling, a base station can transmit updates of configuration parameters in an RRC signal or a DCI signal to a UE. For example, the base station can transmit to the second UE a third RRC signal comprising information to update one or more configuration parameters for transmission without concession specified by the second RRC signal. In another example, the base station may transmit, to the second UE, a second DCI signal specifying information to update one or more configuration parameters for transmission without concession specified by the second RRC signal. After transmitting the updates, the base station can receive a UL transmission without a concession, according to one or more configuration parameters updated for transmission without a concession.

DETAILED DESCRIPTION OF ILLUSTRATIVE MODALITIES [0030] Figure 1 illustrates an example of communication system 100. In general, system 100 allows multiple wireless or wired users to transmit and receive data and other content. System 100 can implement one or more methods of accessing the channel, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA) or single-carrier FDMA (SC-FDMA).
[0031] In this example, the communication system 100 includes user equipment (UEs) 110a-110c, radio access networks (RANs) 120a-120b, a main network 130, a public switched telephone network (PSTN) 140, the Internet 150 and other networks 160 Although certain numbers of these components or elements are shown in Figure 1, any number of these components or elements can be included in system 100.
[0032] UEs 110a-110c are configured to operate and / or communicate on system 100. For example, UEs 110a-110c are configured to transmit and / or receive via wired or wireless communication channels. Each UE 110a-110c represents any suitable end user device and may include devices (or may be referred to) as user equipment / device (UE), wireless transmit / receive unit (WTRU), mobile station, unit

15/87 fixed or mobile subscriber, cell phone, personal digital assistant (PDA), smartphone, laptop, computer, touchpad, wireless sensor or consumer electronic device.
[0033] RANs 120a-120b here include base stations 170a170b, respectively. Each base station 170a-170b is configured to wirelessly interface with one or more of the UEs llOa-llOc to allow access to main network 130, PSTN 140, Internet 150 and / or other networks 160. For example, stations base 170a-170b may include (or be) one or more of several known devices, such as a transceiver base station (BTS), a NodeB (NodeB), an evolved NodeB (eNodeB), a Home Node, a Home eNode, a site controller, an access point (AP), a wireless router, or a receive-transmit point (TRP). The llOa-llOc UEs are configured to interface and communicate with the Internet 150 and can access main network 130, PSTN 140 and / or other networks 160.
[0034] In the embodiment shown in Figure 1, base station 170a is part of RAN 120a, which can include other base stations, elements and / or devices. In addition, base station 170b is part of RAN 120b, which may include other base stations, elements and / or devices. Each base station 170a-170b operates to transmit and / or receive wireless signals within a specific region or geographical area, sometimes called a cell. In some modalities, the technology of multiple inputs and multiple outputs (MIMO) can be used having multiple transceivers for each cell.
[0035] Base stations 170a-170b communicate with one or
Petition 870190116979, of 11/13/2019, p. 22/100
16/87 more of the UEs 110a-110c through one or more interfaces
190 using links of Communication wireless. At interfaces 190 airlines can use any technology in access by adequate radio. [0036] It is contemplated that the system 100 can use The
multiple channel access functionality, including schemes as described above. In particular modalities, base stations and UEs implement LTE, LTE-A and / or LTE-B. Obviously, other multiple access schemes and wireless protocols can be used.
[0037] RANs 120a-120b are in communication with main network 130 to provide UEs 110a-110c with voice, data, application, Voice over Internet Protocol (VoIP) or other services. Understandably, RANs 120a-120b and / or main network 130 may be in direct or indirect communication with one or more other RANs (not shown). Core network 130 can also serve as gateway access to other networks (such as PSTN 140, Internet 150 and other networks 160). In addition, some or all UEs 110a-110c may include functionality for communicating with different wireless networks over different wireless links using different wireless technologies and / or protocols. Instead of wireless communication (or in addition), UEs can communicate via wired communication channels to a service provider or switch (not shown) and to the Internet 150.
[0038] Although Figure 1 illustrates an example of a communication system, several changes can be made in Figure 1. For example, communication system 100 can include any number of UEs, base stations, networks or others
Petition 870190116979, of 11/13/2019, p. 23/100
17/87 components in any suitable configuration.
[0039] Uplink transmissions without concession are sometimes called transmissions without concession, free of schedule or without scheduling, or transmissions without concession. Uplink transmissions without granting different UEs can be transmitted using the same projected resources; in this case, uplink transmissions without a concession are contention-based transmissions. Uplink transmissions without concession may be suitable for transmitting short packet burst traffic from the UEs to the base station and / or for transmitting data to the base station in real time or with low latency. Examples of applications in which an uplink transmission scheme without concession can be used include: massive machine-type communication (m-MTC), ultra-reliable low-latency communications (URLLC), smart electrical meters, smart grid teleprotection, and autonomous steering. However, uplink transmission schemes without concession are not limited to these applications.
[0040] The uplink resources in which transmissions without a concession are sent will be referred to as uplink resources without a concession. For example, free uplink resources may be a region projected on an OFDMA framework. UEs can use the projected region to send their uplink transmissions without concession, but the base station does not know which of the UEs, if any, will send an uplink transmission without concession in the projected region.
[0041] Uplink resources without concession
Petition 870190116979, of 11/13/2019, p. 24/100
18/87 can be predefined, for example, previously known to the UEs and the base station. Uplink resources without concession can be static (never change) or uplink resources without concession can be configured semi-statically. A semi-static configuration means that it is configured once and is updated / changed only slowly, such as once in many frames or can be updated only as needed. A semi-static change differs from a dynamic change in that a semi-static change does not occur as often as a dynamic change. For example, a dynamic change / update can refer to a change in each subframe or every few subframes, and a semi-static change can refer to a change that occurs only once every several OFDM frames, occurs every few seconds or is updated only if necessary.
[0042] In some embodiments, uplink resources without concession can be preconfigured, for example, there can be a plurality of predefined uplink resource partitions possible, and the base station or network can choose semi- statically one of the predefined uplink resource partitions without concession and signal to the UEs the uplink resource partition without concession being used. In some embodiments, the base station and / or UEs can be configured during their manufacture to know which uplink resources should be used as uplink resources without concession, for example, through predefined tables loaded during manufacturing. In some modalities, uplink resources without
Petition 870190116979, of 11/13/2019, p. 25/100
19/87 concession can be configured semi-statically, for example, using a combination of broadcast signaling, upper layer signaling (RRC signaling) and dynamic signaling (for example, DCI signaling or, equivalently, Ll signaling) by the base station. By dynamically signaling uplink resources without a concession, the base station or network can adapt to the traffic load of the UEs system. For example, more uplink resources without a concession can be allocated when there are more UEs in service that can send uplink transmissions without a concession. In some embodiments, a control node (for example, a computer) on the network can determine the uplink resources without concession to be used. The network can then indicate the uplink resources without concession to the base station and the UEs. In some embodiments, a UE operating in a non-concession mode can be configured semi-statically to combine: 1) RRC signaling information and system information; or 2) the RRC signaling information and the DCI information; or 3) RRC signaling information, system information and DCI information to determine an assigned transmission resource.
[0043] A message can be sent by the UE in an uplink transmission without concession through the uplink channel. The message is transmitted using a multiple access (MA) feature. An MA resource includes a physical MA resource (for example, a time frequency block) and at least one MA subscription. The MA subscription can include (but is not limited to) at least one of the following: a code book / codeword, a
Petition 870190116979, of 11/13/2019, p. 26/100
20/87 sequence, an interleaver and / or mapping pattern, a pilot, a demodulation reference signal (for example, a reference signal for channel estimation), a preamble, a spatial dimension or a power dimension. The term pilot refers to a signal that includes at least one reference signal, for example, a demodulation reference signal. The reference signal can be the MA signature. In some embodiments, the pilot may include the demodulation reference signal, possibly together with a preamble oriented channel estimation or a random access channel preamble (LTE type RACH).
[0044] In some modalities, uplink transmissions may use non-orthogonal multiple access (NOMA), such as: multiple access by sparse code (SCMA), multiple access by interleaved grid (IGMA), access shared by several users (MUSA) , low code rate spreading, frequency domain spreading, non-orthogonal coded multiple access (NCMA), pattern division multiple access (PDMA), resource spreading multiple access (RSMA), low density spreading with extension signature vector (LDS-SVE), low code rate and subscription-based shared access (LSSA), non-orthogonal coded access (NOCA), interleaving division multiple access (IDMA), repetition division multiple access (RDMA) or group orthogonal coded access (GOCA). Depending on the multiple access method used, the MA subscription can take different forms. The MA signature can be related to the specific format used for the multiple access method. For example, if SCMA is used, the MA signature of the
Petition 870190116979, of 11/13/2019, p. 27/100
21/87 uplink transmission can be the SCMA code book used for uplink transmission. As another example, if IGMA is used, the MA signature for the uplink transmission can be the IGMA signature, the interleaving pattern, or the grid mapping used for the uplink transmission.
[0045] To make uplink transmissions without concession (GF), a UE must have complete information about UL GF transmission resources. Generally, some of the GF information can be obtained from a base station's transmission system information. For other GF resource information, there are several options to allocate to an UE.
[0046] In 5G, it is possible that all three types of applications use GF transmission: Ultra Reliable Low Latency Communication (URLLC), enhanced Mobile Broadband (eMBB) and massive Machine Type Communication (mMTC).
[0047] Figure 2 illustrates two possible options for allocating GF transmission resources to an UE. As an example, UE1 110a accepts option 1 using a combination of RRC and DCI signaling, and UE2 110b accepts option 2 using only RRC signaling. It should be noted that the option adopted by a UE can be standard or determined when the UE accesses the network, or it can be obtained directly from the transmission system information or it can be determined from any specific UE signaling. The selection of the option may vary from option 1 to option 2 or vice versa, depending on the system load, channel conditions, type of traffic (for example, periodic or aperiodic), type of application
Petition 870190116979, of 11/13/2019, p. 28/100
22/87 (URLLC, eMBB, mMTC), packet size, etc. The selected option can be semi-static or dynamically adjusted. According to this disclosure, option 1 and option 2, or more GF signaling options, can coexist to provide resource configuration for transmissions without concession. In addition, some channels may be shared by transmissions without concession and based on the concession of the same user or different users, for example, some ACK / NACK return channel, such as a UE-specific PDCCH or a common group PDCCH channel. Thus, a signaling message can include both configuration information without concession and based on configuration information.
[0048] In step 201, UE1 is performing an initial access to the system.
[0049] In step 202, the base station (BS 170) selects a GF resource configuration option for UE1. In this example, option 1 is selected for UE1.
[0050] In step 203, the BS notifies UE1 that a combination of RRC configuration and DCI / Layer 1 signaling configuration (option 1) is selected for UE1. UE1 can receive this notification right after its initial access, either through BS broadcast information, or predefined, or through any specific UE signaling, such as downlink control (DCI) information or signaling of resource control of radio (RRC) or any type of non-DCI signaling or any multiplexed broadcast signaling. Therefore, option 1 is generally a signaling scheme in a combination of non-DCI signaling and allocation of DCI signaling. As used in this document, the
Petition 870190116979, of 11/13/2019, p. 29/100
23/87 non-DCI signaling can be RRC, broadcast or multiplex broadcast, a combination of two of them or a combination of the three.
[0051] In step 204, with option 1, a part of the resource configuration information is transmitted from BS to UE1 through non-DCI signaling (such as broadcast, multiplexed broadcast or RRC), for example, periodicity information. In other modalities, the periodicity can be defined as 1, meaning that any resource to be allocated by DCI signaling and the resource can be used by the UE in any time interval, that is, the resource in the frequency domain without time limitation for use; meanwhile, the user transmits nothing if the UE has no data in its buffer, and the user's retry and retransmissions may use the same or different resources configured / allocated by DCI signaling.
[0052] In step 205, with option 1, another part of the resource configuration information is transmitted from BS to UE1 through DCI (Physical Downlink Control Channel, in short as PDCCH) or PDCCH signaling of common group. DCI signaling can include at least any of the following information, but is not limited to: GF resource size in the frequency domain, resource hop pattern, explicit or implicit signaling of time / frequency / actual RS resources or resource indices , modulation and coding scheme (MCS) which can be UE specific (eg fixed value) or resource specific (eg MCS jump pattern on different resources), number of K repetitions that is UE specific and can be combined with the size of the TTI cluster. a
Petition 870190116979, of 11/13/2019, p. 30/100
24/87 or more MCS schemes and / or one or more K values can be configured for a user. The UE feature can be updated or changed, or disabled at any time by the DCI type dynamic signaling configuration, while the UE can confirm or not the dynamic signaling configuration.
[0053] In step 206, UE1 collects all UL GF transmission resources configured from steps 204 and 205 and possibly transmits the signaling, if any.
[0054] In step 207, UE1 and BS make GF transmissions and corresponding responses based on configured resources and traffic arrivals.
[0055] In step 208, the BS can terminate or disable the configuration information by non-DCI signaling or DCI signaling. If a UE receives a DCI termination or deactivation signal, it can assume that the information obtained in the DCI configuration is discarded and the UE must wait for another DCI configuration before any GF transmission or wait for the signaling of another option or contingency for the standard option, in which the termination or deactivation of the DCI feature can be based on several factors, such as the silent UE for a configurable period without transmitting any data.
[0056] UE2 performs similar steps, but the option 2 signaling scheme is necessary, in which the configuration
of the resource > GF it will be fulfilled just for signaling not DCI. [0057] At stage 251, UE2 do an ace this initial to system. [0058] At stage 252, the BS selects one option in
GF resource configuration for UE2. In this example, the option
Petition 870190116979, of 11/13/2019, p. 31/100
25/87 is selected for UE2.
[0059] In step 253: BS notifies UE2 that the non-DCI signaling configuration (option 2) is selected for UE2. UE2 can receive this notification shortly after its initial access, or from BS broadcast information, or predefined, or from any specific UE signaling, such as downlink control (DCI) information or signaling of resource control of radio (RRC) or any type of non-DCI signaling or any multiplexed broadcast signaling. Option 2 includes only non-DCI signaling and does not require DCI signaling for resource configuration.
[0060] In step 254, with option 2, resource configuration information is transmitted from BS to UE2 by means of non-DCI signaling (such as broadcast, multiplexed broadcast or RRC), for example, contention transmission unit ( CTU) defined as a combination of at least part of the time / frequency and RS resources, one or more jump patterns based on the resource index in the time domain and / or frequency domain and / or even signal (s) reference numbers, one or more MCSs, one or more K repetition factors, etc. In another mode, the configuration of the GF resource can be per user or per cell; one or more RSs, MCSs and or Ks can be based on GF resources. The configuration of resources and parameters can be updated semi-statically by non-DCI signaling and / or dynamically by DCI signaling, where, if both signaling schemes are applied, a rule or protocol must be determined in terms of, for example, what is changing and scope of application, such as applicable time period (a TTI or for
Petition 870190116979, of 11/13/2019, p. 32/100
26/87 always) and for the current transmission block or not, etc.
[0061] In step 255, UE2 collects all configured UL GF transmission resources from 254 and possibly transmits signaling, if any.
[0062] In step 256, UE2 and BS make GF transmissions and corresponding responses based on configured resources and traffic arrivals.
[0063] UE1 with option 1 needs to monitor the DCI, and UE1 cannot do the GF transmission without the information included in the DCI configuration. The UE2 with option 2 does not need to monitor the DCI, and the UE2 can perform the GF transmission shortly after receiving the GF resource configuration based on non-DCI signaling. In some other scenarios, the UE2 can still monitor the DCI for control signaling, although it can perform GF transmission without configuring / activating the DCI.
[0064] With option 2, it is not necessary to have the step to end or disable the feature. Option 2 is best suited for periodic UL traffic, while option 1 is best suited for aperiodic traffic. But there are no strict limitations anyway. An aperiodic transmission with option 1 or a periodic transmission with option 2 is still possible. When a UE has periodic and aperiodic traffic, it is also possible for that UE to take both options. In some modalities, with option 2, the GF resource can still be terminated / disabled semi-statically (for example, through RRC) or dynamically (for example, through DCI).
[0065] In a system, it is possible that different users have different options to obtain the configuration of the
Petition 870190116979, of 11/13/2019, p. 33/100
27/87 appeal; or the same user may have a signaling scheme and then switch to another signaling scheme based on factors such as type of traffic and system loading and user application scenarios and requirements, etc. In addition, a GF user can also be configured at the same time as concession-based transmissions, where the configuration signaling used for concession-based transmission can be the same or different from the GF signaling scheme.
[0066] For both options, the configuration options can be cell-specific or EU-specific or group-specific. It is also possible that this option flag may be implicit, mapping the option information from any other information, which can be, without limitation, any of the following: predefined based on the type of device, the UE ID or the information about periodicity. For example, if an RRC signal indicates only the periodicity information, a UE knows that it is option 1 because it needs to wait for a DCI for further configurations and / or activation of resources and access the resource for transmission according to the periodicity. On the other hand, if an RRC signaling already includes sufficient resource information needed for transmission without a concession (which may or may not be combined with transmission resource information), an UE knows it is option 2 and does not need to wait for an INN . In this sense, there will be no step 203/25 3. Likewise, a UE can decide if the signaling option is option 1 or 2, verifying whether the RRC contains the sufficient resource configuration information necessary for the GF transmission (can or not be combined
Petition 870190116979, of 11/13/2019, p. 34/100
28/87 with transmission resource information). For example, if the resource configuration does not include the frequency location or the size of each allocated resource (for example, number of physical resource blocks (PRBs) or virtual resource blocks (VRBs)), this indicates the use of the option 1, that is, it requires complementary DCI signaling for the configuration of resources. If the resource configuration includes the frequency location or the size of each allocated resource (for example, number of physical resource blocks (PRBs) or virtual resource blocks (VRBs), this indicates the use of option 2, that is, does not require complementary DCI signaling for resource configuration.
[0067] In an implementation, when there is a standard option for GF UE, option 1 or option 2, step 202/252 and the subsequent steps are triggered by changing the system load or channel conditions, type of traffic ( for example, periodic or aperiodic), type of application, package size, etc. For the standard option, the explicit indication is also not necessary. In this case, if the selected option is the same as the default option in step 202/252, there will be no step 203/253, which can also be considered as implicit signaling.
[0068] It is also possible for a UE, explicitly or implicitly (for example, by type of application or by type of traffic), to indicate its preference for which signaling options to use, for example, in step 201/251 or other steps.
[0069] In options 1 and 2, some of the common information (not specific to the UE) can be signaled in the broadcast or multiplexed broadcast signaling instead of RRC or DCI. Per
Petition 870190116979, of 11/13/2019, p. 35/100
29/87 example, the definition of the GF resource unit or the containment transmission unit (CTU) may be common to all UEs. The information can be specified in the broadcast or multiplexed broadcast signaling, for example, in the system information block (SIB). The total region of resources for GF transmission can also be signaled in the signaling of diffusion or multiplexed diffusion, for example, in the SIB.
[0070] In Figure 2, two options have been described, but the notification scheme for the option described still applies if more than two options are supported in the system.
CONCESSION-FREE AND CONCESSION-BASED RESOURCES [0071] In a new Novo Rádio (NR) wireless system, any user can be configured as broadcast based on concessions and / or without concessions, depending, for example, on the application and / or types and device requirements. Generally, a broadcast without a concession may require (pre-) configuration of resources in the configuration of the user's connection and have resource reconfiguration or updating during transmissions. In some modalities, resources without concession can be configured for users by means of broadcast or multiplexed broadcast signaling in some scenarios, for example, in idle or idle mode. Two or more broadcasts without a concession can share the same configured resources; and a concession-based transmission can use dedicated resources or can compete (in whole or in part) with non-concession resources over a period of time.
[0072] Any transmission without concession and based on concession can be used for any type of traffic or application services, depending on the requirements of
Petition 870190116979, of 11/13/2019, p. 36/100
30/87 associated applications and quality of services (QoSs). For example, a broadcast without a concession can be used for a user with some URLLC traffic to satisfy the extremely low latency requirement; can be used for a user with short eMBB traffic packets to save signaling overhead; a concession-based broadcast can be used for a user with some URLLC traffic with reasonable latency requirements; can be used by a user with eMBB traffic to take dynamic advantage of link adaptation and improve resource utilization and spectrum efficiency.
[0073] A user or a group of users can have a group ID or RNTI (for example, GF-RNTI, GB-RNTI) to share the same parameter and / or resource configuration. The group ID can be pre-defined, broadcast / broadcast multiplexed over several transmissions, pre-configured or dynamically configured for each user; the parameter or resource configuration for the user (s) with the group ID can be done by diffusion, multiplexed diffusion, RRC signaling and / or DCI based dynamic signaling (for example, user specific DCI or PDCCH of common group). In one embodiment, each UE with a common resource / parameter configuration using a group ID can have its specific (or unique) parameter (s), such as DMRS, to differentiate it from other UEs, in a different way. predefined, pre-configured or pre-mapped to the UE. In some modalities, the group ID can be used for, for example, deactivation and / or activation of resources for users of the group, where the resource includes frequency, time, reference signal (RS)
Petition 870190116979, of 11/13/2019, p. 37/100
31/87 associated with each user in the group.
FEATURES AND PARAMETERS TO BE CONFIGURED FOR A CONCESSION-FREE TRANSMISSION [0074] To support non-concession transmissions, the associated resources configured for a user or a group of users include the following: 1) resources and frequency size in TTI (for example , a symbol, mini-interval or interval): virtual resource block (VRB) scheme that indicates RB and virtual startup size and is associated with the frequency jump, assuming that the user or group of users has received the sub division -band and carrier bandwidth information from broadcast or multiplexed broadcast signaling; or, physical RB (PRB) scheme indicating size and initial physical RB; 2) resources and time period, including the accessible start / end position of a data transmission time slot (for example, TTI can be a symbol, mini-slot or slot) and time slot resource frequency (for example, 0 represents all resources of the time period), 1 represents all other resources of TTI, 2 represents every two resources of TTIs and so on) and reference of start time (for example, first symbol in a sub- frame); 3) RS or RS configuration, where each user can be configured with one or more reference signals (RSs or DMRSs) depending on the scenarios, for example, the initial RS transmission can be different from the RS retransmission to identify the user initial and retransmissions of a block transmission (TB) for possible HARQ signal combination and detection; in one modality, one
Petition 870190116979, of 11/13/2019, p. 38/100
32/87 user can be (pre-) configured or assigned to an RS for initial transmissions, while the user's relay RS (s) can be derived from a configured mapping rule or a predefined mapping, or a set of RSs can be (pre-) configured or explicitly assigned to initial and retransmissions, respectively. In addition, different reference signals can also identify different UL transmission ports and / or different UL beams, or a different UL RS can indicate which different DL beam is received with strong signal strength. For a group of users, each user may or may not have a different RS or have a different set of RSs. Note that different RSs can be orthogonal or non-orthogonal, depending on scenarios such as different applications, for example, URLLC or mMTC service; 4) jump parameters specific to the EU / EU group, including two parameters. One is the jump pattern cycle period: absolute reference duration (for example, 20 TTI before repeating), where, based on the periodicity of accessible time slot resource (for example, 2 TTI), the number of hops (for example, 10 times) to be made before repeating the pattern again (for example, 10) can be determined; or, absolute number of jump times (for example, jump 20 times before repeating). The other is the jump pattern index or indexes, where a user can have one or more jump pattern indexes; 5) one or more HARQ process IDs per user. A maximum number of retransmission times or a timer from the start of a TB transmission can be set or configured to release an HARQ buffer if the TB transmissions are associated
Petition 870190116979, of 11/13/2019, p. 39/100
33/87 to the HARQ buffer are not successful for some period of time; 6) one or more MCSs per user, where a user without a concession can indicate explicitly or implicitly which MCS to use for a broadcast, for example, using a different pilot to represent a different MCS among the MCSs configured for the user or using a resource Pre-configured FG associated with a pre-configured MCS, known to users and a base station, or using the UL control channel to indicate which MCS is in use before or at the same time with data transmission; 7) the number of K repetitions, one or more K values can be configured for a user, where the K value to be used depends on certain rules, such as user channel conditions, types of service, etc .; 8) at least two parameters to control a valid use of resources without concession: one used as a flag, for example, Fl, if it is enabling / disabling / releasing (for example, 0, disable; 1, enabling), one used as a flag, for example, F2, to indicate the on / off status (for example, 0, off; 1 on); 9) a parameter for configuration, including an indication if a user without a concession is enabled or not to activate data transmission during the OFF Period of Discontinuous Reception (DRX) after the arrival of the package; 10) power control parameters, including the size of the power increase step (for example, for a beam); 11) one or more bandwidth portion (BWP) configurations, each including numerology (for example, sub carrier spacing and CP / overhead type), bandwidth of a portion of bandwidth, initial frequency location for the bandwidth part, etc.
Petition 870190116979, of 11/13/2019, p. 40/100
34/87
These parameters can be used for BWP configurations, the activation of standard active or active BWPs and / or the disabling of BWPs / BWPs' to be exchanged (and to be deactivated) / to (and to be activated); 12) type of waveform, for example, CP-OFDM or DFT-s-OFDM; 13) other parameters, including information associated with general data based on concessions and transmissions of control. Note that sometimes a subset of resources without a concession can be called fixed or reserved resources; whereas a subset of grant-based resources can be called flexible resources, which can be dynamically scheduled by a base station.
[0075] To support a concession-based transmission, a user access facility is generally dynamically scheduled every time interval, except in cases where a user facility can be dynamically scheduled once, but used for more than an interval, such as DCI or Layer 1 (Li) activation on the SPS, or a transmission with grouping or repetitions. A grant-based resource is not necessarily required to be preconfigured for a user before grant-based transmission, which is different from a non-grant resource configuration.
[0076] In some modalities, resources without concession can be configured for data transmissions, transmissions of control messages (dedicated to a user or shared by a group of users) or a combination of control and data transmissions. For example, an advanced scheduling (SR) request can be designed to use an unqualified resource to reduce latency
Petition 870190116979, of 11/13/2019, p. 41/100
35/87 request, which may or may not be shared by multiple users. For a non-grant resource configured only for control messages such as SR, UE return, measurement reports (for example, a beam measurement report, a measurement report based on CSI-RS, a measurement report based on DM-RS ), the non-grant resource may or may not be shared by multiple users. In another embodiment, a resource without a concession can be configured for one or more users on the polling reference signal (SRS) UL or tracking signals, for example, a user can use the resource without concession to send aperiodic SRS signals. In other embodiments, a concession-based resource can be used by a UL control signal that can include a request for non-concession services, for example, a scheduling request (SR) on the dedicated PUCCH channel can include an indication for the base station to request GF resource configuration, activation or reconfiguration for the type of traffic without concession and transmissions without concession. In addition, the SR can also include information in the request message, for example, an indication of (new) MCS and numerology parameters to be used, packet size to be transmitted, remaining power surplus space, etc., for transmissions without UL concession.
SHARED SIGNALING WITHOUT CONCESSION AND BASED ON CONCESSION [0077] Due to the nature of transmission without concession, the system design should consider some specific types of signaling for transmissions without concession, for example, RRC configuration of resources without concession for a user
Petition 870190116979, of 11/13/2019, p. 42/100
36/87 or a group of users, configuration of resources without concession in idle or idle mode of the user, some specific mechanisms for control or management in transmissions without concession, as parameters to indicate whether an activation, deactivation and / or release of resources without granting one or more users may be allowed.
[0078] In general, non-concession and concession-based users and transmissions can share one or more common types of control signaling, such as DCI, RRC, LTE-type RAR and broadcast, etc., for the resource and / or parameter configuration, including minimal system information for control and data transmission, for example, configuration of numerology division parameters and transmission sub-band (explicit or implicit) or RRC signaling, DCI MCS update, etc. A shared signaling format can be the same as an LTE-based or NR-based format; or a shared signaling format can be a command format modified from the concession-based signaling format or a harmonized signaling format for concession-based and non-concession transmission configuration.
[0079] In some modalities, one or more common types of control signaling may have the same format that works for non-concession and concession-based transmissions. For example, the same signaling format for concession-based transmission control can be used for transmission control without concession, for example, one or more bits of information in the format with different values may indicate a transmission in terms of
Petition 870190116979, of 11/13/2019, p. 43/100
37/87 type / user / transmission resource based on concession or without concession, but the signaling format can provide the same control context in the parameter (s) and / or transmission resources, for example, a resource allocation with configuration RS, MCS, DRX and RRC idle / idle configuration, etc.
[0080] In other modalities, one or more common types of control signaling may have a harmonized format considering additional control requirements without concession, in addition to a signaling format based on concession. For example, increasing the length of the information bit to one or more parameters / elements in a concession-based signaling format to indicate more options, including control or signaling contexts without concession; or add more elements in a concession-based signaling format to include specific control contexts for non-concession transmissions. It would be more efficient if the control contexts in a shared signaling were the same for concession-based and non-concession transmissions; in other cases, the same control context (for example, RS, MCS) in a shared and common signaling must be considered in the design of the signaling for transmission based on concession and without concession.
[0081] These considerations about signaling without specific concession and shared signaling projects can make the coexistence of non-concession and concession-based transmissions an integral network and operate very effectively and efficiently.
CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION A: SCHEME
Petition 870190116979, of 11/13/2019, p. 44/100
38/87
RRC-BASED [0082] Before configuring non-concession resources (FG) for a user or group of users by RRC signaling, some associated non-concession information can be broadcast or multiplexed from the base station to users as transmission numerology without concession, sub-band division, sub-band locations, optionally, group ID (s) for non-concession users, etc., where this concession information can be sent along with other common broadcast / multiplexed broadcast information concession-based general terms.
[0083] During the user network entry with the connection configuration, the RRC signaling configures for a user without concession or a group of users without concession (with a group ID) the resources and GF parameters described in a previous paragraph, including time / frequency / RS, jump, HARQ process (s), MCS (s) and K (s) and following parameters.
[0084] The two parameters associated with the activation and deactivation of resources to control a valid use of resources without concession are configured: one used as a flag, for example, Fl, to indicate whether the activation / deactivation / release is activated (for example, 0, disable; 1, enable) is allowed, which is a configurable feature capable of applying LI signaling for activation, deactivation and / release of dynamic resources; one used as a flag, for example, F2, to indicate the on / off status (for example, 0, off; 1 on). If Fl is set to off, F2 can be set to any value (0 or 1) and the UL transmission
Petition 870190116979, of 11/13/2019, p. 45/100
39/87 without concession can be performed by a UE without any LI activation. If F1 is configured to activate, F2 can be used to indicate the true or not feature activation state, where F2 being the activated value (1) means that UL transmission without concession can be performed by a UE after semi configuration -static (without any additional Ll / DCI activation), which can at least be used for configuring URLLC applications and services, and F2 with the value deactivated (0) means that the UL transmission without concession needs to wait for more activation signals LI before starting any data transmission, which can at least be used for configuring periodic traffic, such as VoIP applications.
[0085] The DRX parameters can be configured, in which the user behavior without concession may or may not be the same as the user based on concession. At least one more specific parameter for DRX behavior without concession can be defined to indicate whether a user without concession can activate in advance after the arrival of the package during the DRX OFF period for data transmission. After configuring the semi-static resource, the RRC signaling performs semi-static reconfiguration for a user without a concession or a group of users without a concession (with a group ID) on the GF resources and parameters described in a previous paragraph, including time / frequency / RS, jump, HARQ process, MCS (s) and K (s), the two parameters associated with enabling and disabling the feature, and DRX parameters.
[0086] From the user's perspective, a user without a concession may or may not interrupt the DRX inactivity timer and the onDuration timer when receiving the
Petition 870190116979, of 11/13/2019, p. 46/100
40/87 MAC CE DRX command from the base station, depending on whether a user without a concession is configured and can activate a packet arrival in advance during the DRX OFF period for data transmission.
[0087] In this option, by default, F1 is set to disable; or F1 is set to activate and F2 is set to activated by the RRC signal. As a result, UL transmission without concession can be performed by a UE after the semi-static configuration of resources by the RRC, without any LI activation.
CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION B: SCHEME BASED ON ACTIVATION / DEACTIVATION [0088] In this scheme, resources without concession are configured by the upper layer / RRC signaling and the common Ll / group PDCCH signaling before a user without a concession starts a UL data transmission.
[0089] For the configuration of RRC resources, it is the same as that provided in the CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION A: RRC-BASED SCHEME.
[0090] For signaling based on common group PDCCH, the parameters or contents in the signaling include activation / deactivation / release of user resource, ACK / NACK return or confirmation to UL data transmissions from users without concession and / or based on concession. In addition, LI signaling can also update link parameters, for example, MCS, K, power control, etc.
[0091] In this option, by default, F1 is set to activate, which allows an activation and deactivation of LI for configuration without concession, and F2 is defined as
Petition 870190116979, of 11/13/2019, p. 47/100
41/87 disabled by RRC. As a result, after RRC semi-static resource configurations, a user without a concession needs to wait for LI or bundle the common PDCCH activation signal before transmitting without a UL concession.
CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION C: SCHEME BASED ON ACTIVATION / DEACTIVATION [0092] In this scheme, resources without concession are configured by both the upper layer / RRC signaling and the Ll / DCI (or EU specific PDCCH) signaling before an user without a concession initiates a UL data transmission.
[0093] For the configuration of RRC resources, it is the same as that provided in the CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION A: RRC-BASED SCHEME.
[0094] For DCI-based signaling, the parameters or content in the signaling include user resource activation / deactivation / release. In addition, Ll / DCI signaling can also update the link parameters in, for example, MCS, K, power control, etc.
[0095] In this option, by default, F1 is set to activate, which allows an activation and deactivation of LI for configuration without concession, and F2 is defined as deactivated by RRC. As a result, after RRC semi-static resource settings, a user without a concession needs to wait for the LI or DCI activation signal before transmitting without UL concession.
CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION D: SCHEME BASED ON ACTIVATION / DEACTIVATION [0096] In this scheme, resources without concession are
Petition 870190116979, of 11/13/2019, p. 48/100
42/87 configured by upper layer / RRC signaling and Ll / DCI signaling before a non-concession user initiates UL data transmission.
[0097] For the configuration of RRC resources, it is the same as that provided in the CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION A: RRC-BASED SCHEME.
[0098] In this case, a transmission without a concession can be temporarily or permanently switched to transmission based on concession by scheduling Ll / DCI and concession signaling, where one more parameter can be defined to indicate the type of switching, as only for this one. transmission or switching from TB to concession-based transmission permanently. In some modalities, a transmission without granting a user TB can be switched to grant-based transmissions for the user TB by scheduling Ll / DCI and grant signaling, where a temporary switching is assumed. In some embodiments, a concession-based transmission can be switched to non-concession transmission, for example, using the concession-based user's scheduling request to indicate a transmission request without a concession. In other modalities, a grant-based broadcast user can use a non-grant resource for a scheduling request to save request latency, where the SR can include the request information, such as traffic type, buffer size, numerology, type of transmission based on concession or without concession, and a new MCS selection, etc. In another modality, a resource without a concession can be used exclusively by one or more users for the transmission of
Petition 870190116979, of 11/13/2019, p. 49/100
43/87 control messages, including SR, UL return, measurement reports, etc.
[0099] For DCI-based signaling, the parameters or content in the signaling include deactivating / releasing / reactivating user resources, returning ACK / NACK or confirming UL data transmissions from non-concession and / or concession-based users. In addition, Ll / DCI signaling can also update the link parameters in, for example, MCS, K, power control, etc.
[00100] In this option, by default, F1 is defined as active and F2 is defined as activated by RRC. As a result, UL transmission without concession can be performed by a UE after semi-static resource configuration by RRC without any Ll / DCI activation, but DCI signaling is able to switch between a continuous transmission without concession to a concession-based transmission. , as well as apply resource deactivation, release, or reactivation without a concession (or reactivation with a resource configuration without a concession after signaling the resource release).
CONFIGURATION OF RESOURCES WITHOUT GRANTING OPTION E; ACTIVATION / DEACTIVATION-BASED SCHEME [00101] In this scheme, resources without concession are configured either by the upper layer / RRC signaling or by Ll / DCI (or EU-specific PDCCH) signaling before a user without a concession starts a data transmission UL, where all associated resources without concession concession will be divided into two parts to be configured separately by RRC signaling and Li signaling.
[00102] In some modalities, except for resources without
Petition 870190116979, of 11/13/2019, p. 50/100
44/87 granting of time / frequency / MCS (s) / number of repetitions K (s), which will be configured by the Ll signaling, the other resources can be configured by the RRC signaling in a similar way to that described in the section RESOURCE CONFIGURATION WITHOUT GRANT OPTION A: RRC-BASED SCHEME. In other modalities, the non-concession resources listed in the CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION A: RRC-BASED SCHEME can be divided into two portions in very different ways, for example, RS, hop pattern and HARQ process can also be configured by Ll / DCI Signage.
[00103] For DCI-based signaling, the parameters or content in the signaling include user resource activation / deactivation / release. In some modalities, DCI can also configure resources without granting time / frequency / MCS (s) / number of repetitions K (s) for a user or a group of users (with the same group ID); in other modalities, DCI can also configure resources without granting time / frequency / MCS (s) / number of repetitions K (s), plus RS, hop pattern and HARQ process for a user or a group of users. In addition, Ll / DCI signaling can also update the link parameters in, for example, MCS, K, power control, etc.
[00104] In this option, by default, F1 is set to activate, which allows an activation and deactivation of Ll for configuration without concession, and F2 is defined as deactivated by RRC. As a result, after RRC semi-static resource settings, a non-concession user needs to wait for the Ll or DCI activation signal before
Petition 870190116979, of 11/13/2019, p. 51/100
45/87 of the transmission without UL concession.
CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION F: A COMBINATION OF RRC CONFIGURATION AND PCI / LAYER SIGNALING SCHEME 1 [00105] In this scheme, resources without concession are configured by both the upper layer / RRC signaling and the Ll / DCI signaling (or PDCCH) specifies UE) before a user without a concession initiates a UL data transmission, where all associated resources without a concession will be divided into two parts to be configured separately by RRC signaling and LI signaling.
[00106] In some modalities, resources without time / frequency / MCS (s) / number of repetitions K (s), RS, hop pattern and HARQ process are configured by DCI / L1 signaling for a user or a group of users (with the same group ID) and the other resources can be configured by RRC signaling in a similar way to that described in the section CONFIGURING RESOURCES WITHOUT CONCESSION OPTION A: RRC-BASED SCHEME. In addition, RRC will also set parameters for periodicity and resource usage timers (s), etc .; for URLLC services, periodicity can be defined as a small number (for example, 1) and resource timers can be defined as a large number (for example, infinite).
[00107] For DCI-based signaling, the parameters or content in the signaling include activation / deactivation / release of user resources. In addition, Ll / DCI signaling can also update the link parameters in, for example, MCS, K, power control, etc.
Petition 870190116979, of 11/13/2019, p. 52/100
46/87 [00108] In this option, by default, F1 is set to activate, which allows an activation and deactivation of LI for configuration without concession, and F2 is defined as deactivated by RRC. As a result, after RRC semi-static resource settings, a user without a concession needs to wait for the LI or DCI activation signal before transmitting without UL concession.
RESOURCE CONFIGURATION SIGNAL CONFLICT AND RESOLUTION [00109] A non-grant resource or group of resources configured for a user can be activated, deactivated, released, reconfigured and / updated in a semi-static, dynamic and a combination of both ways . The semi-static way includes the use of base station signaling, such as RRC, diffusion, multiplexed diffusion and / or others; the dynamic way includes the use of signaling, such as user-specific DCI, common group PDCCH and / or others.
[00110] However, Ll / dynamic signaling and upper layer signaling can have a conflict when configuring, reconfiguring and / updating user resources / parameters, for example, applying different values to the same parameter or an indication of controversial action to the same user. This is due to the possibility of different types of signaling of LI messages and control of the upper layer, applicable to the same resource, parameter and / or user without concession. For example, semi-static / top-layer signaling can be used to reconfigure an MCS, MCSi, and dynamic / Ll signaling can be used to update a different MCS, MCSk for a user or resource in the same time interval. In this case, the
Petition 870190116979, of 11/13/2019, p. 53/100
47/87 conflict resolution must be predefined or pre-configured so that the user can follow the instructions unambiguously; for example, if two different MCSs are indicated due to signaling conflict, the more robust MCS will be used or DCI / L1 signaling can replace semi-static signaling or semi-static signaling can replace dynamic / Ll signaling, or a posterior signaling can replace the anterior signaling, etc.
USER BEHAVIOR WITHOUT CONCESSION IN RRC CONNECTED MODE WITH DRX [00111] A transmission user without a concession in a state connected to the RRC can apply the DRX configuration by a DRX scheme that can be independent of the configuration of resources without concession; for example, the current LTE DRX or NR DRX signaling and configuration procedure can be used for non-concession transmissions, in the same way as the concession-based transmission DRX configuration. As a non-concession user configured non-concession resources in the state connected to the RRC, user behavior and base station handling of non-concession resources configured during the DRX ON / OFF cycle are described below.
[00112] From the perspective of the UE, he can use his resources without concession configured immediately, if necessary, after the period of DRX ON. It can optionally be configured to activate activation during the DRX OFF period for data transmission without concession after a packet arrival, where the behavior of the UE must be defined in this case in relation to how to design a mechanism (for example, an impact on the DRX ON / OFF cycle must be described and, at
Petition 870190116979, of 11/13/2019, p. 54/100
48/87 less, a one-bit temporary DRX user ON parameter (to activate or not this early activation) and its definition of active duration after data transmission is requested, etc.) to run current DRX operations smoothly.
[00113] From the point of view of the base station, the resource without concession of a user without concession in the DRX OFF period may or may not be used by other traffic or users, which must be an implementation problem. Depending on the project, if a user without a concession is allowed to activate for a data transmission during the DRX OFF period (on arrival of data), the base station may have a better idea if it tries to borrow and schedule / grant other users or traffic to transmit on resources without concession from user without concession (in the DRX cycle).
[00114] A user can be configured to monitor the DL control channel with the DRX ON period in terms of interval, mini-interval or OFDM symbol with respect to the numerology of the DL control channel, but this may not be applied to all types of users and / or use cases.
RESOURCE CONFIGURATION WITHOUT CONCESSION IN Idle or Idle Mode [00115] A user with non-concession and / or concession-based transmissions can apply an inactive timer to release their RRC connection and at least physical time / frequency resources to enter idle or idle in order to save user power or power, where only partial or no RRC connection context / resources can be maintained.
[00116] In some modalities, the UE can transmit small data without a state transition to the mode
Petition 870190116979, of 11/13/2019, p. 55/100
49/87 connected RRC using transmissions without concession. Non-concession resources can be broadcast or multiplexed to a group of users with a group ID, for example, an RNTI group per user group for uplink transmissions, which may or may not be the same as a paging ID for DL broadcasts. A group ID can be pre-defined or pre-configured for a user during the user's initial network entry or connection configuration. A group of users with the same group ID can share the same time and frequency resources (and, optionally, MCS, K, etc.) configured for them, while an RS for each user can be different, which can be predefined by mapping a user (for example, using their UE ID) to one or more RSs in a predefined or randomly selected RS set in the RS set. In addition, the paging / DRX parameters (Tc, nB) of a group of users can also be configured by diffusion, while the UE-specific DRX cycle (TUE) can be configured through Non-Access Stratum (NAS) signaling. .
[00117] In other modalities, resources without concession in idle or idle mode can be predefined, including time / frequency / RS, as well as other parameters, such as MCS, K and PC. In another mode, a user in an idle state or idle mode can be configurable or optional to receive all or part of the resource and / or parameter settings in their state connected to the RRC.
[00118] Some modalities provide transmission without concession and based on concession with shared signaling for configuration and control. In general,
Petition 870190116979, of 11/13/2019, p. 56/100
50/87 transmissions and users based on concession and without concession and can share one or more common types of control signaling, such as DCI, RRC, diffusion, etc., for the configuration of resources and / or parameters, for example, numerology and configuration of diffusion sub-band parameters or RRC signaling, update of MCS from DCI, etc. A shared signaling format can be the same as the LTE or NR based concession format; or a shared signaling format can be a command format modified from the concession-based signaling format or a harmonized signaling format for concession-based and non-concession transmission configuration.
[00119] Some modalities include a scheduling request that uses the resource without concession to reduce latency. In some embodiments, resources without a concession are configured for data transmissions, transmissions of control messages (dedicated to a user or shared by a group of users) or a combination of data and control transmissions. For example, an advanced scheduling (SR) request is designed to use an unqualified feature to reduce request latency, which may or may not be shared by multiple users. For a non-grant resource configured only for control messages such as SR, UE return or measurement reports, the non-grant resource may or may not be shared by multiple users.
[00120] Some modalities provide resource configuration without grant by RRC with configurable DCI and / or DCI-based resource activation, deactivation or release
Petition 870190116979, of 11/13/2019, p. 57/100
51/87 and / or configurable RRC, as described in the BF Resource Configuration sections without Concession Options B-F above.
[00121] Some modalities provide resolution of the conflict of signaling of the configuration of resources due to the double controls of Ll and DCI. Ll signaling and upper layer signaling can have a conflict, for example, applying different values to the same parameter or an indication of conflicting action for the same user. This is due to the possibility of different types of signaling from Ll and upper layer control messages applicable to the same resource, parameter and / or user without concession. For example, semi-static / top-layer signaling can be used to reconfigure an MCS, MCSi and dynamic / Ll signaling to update a different MCS, MCSk for a user or resource in the same time interval. In this case, the conflict resolution rule must be predefined or pre-configured so that the user follows the instructions unambiguously; for example, if two different MCSs are indicated due to signaling conflict, the more robust MCS will be used or DCI / L1 signaling can replace semi-static signaling or semi-static signaling can replace dynamic / Ll signaling, or a posterior signaling can replace the anterior signaling, etc.
[00122] Some modalities provide user behavior without concession in the connected RRC mode with DRX. Some modalities provide configuration of resources without concession in idle or idle mode.
CONFIGURATION OF RESOURCES WITHOUT GRANTING OPTION G:
[00123] The base station will configure resources and / or
Petition 870190116979, of 11/13/2019, p. 58/100
52/87 concession rate parameters for an UE or an UE group that applies the transmission scheme without concession to transmit uplink data and / or control information. The base station configures resources and parameters without concession to the UE or the UE group through RRC signaling. Non-concession resources comprise at least frequency-time resources. The parameters without concession comprise at least one of the following: RS parameters, MCS index (or indexes) or equivalent transmission block size, number of K repetitions, power control parameters, numerology, subband option.
[00124] In this option, the base station can use RRC signaling in two formats (format A and format B) to configure resources and parameters without concession for a UE. Figure 3 shows an example of two formats: format A 300 and format B 302. In one example, the difference between format A 300 and format B 302 is that format B 302 has an additional filed 304. The additional field 304 it can occupy one or several bits. As an example, the additional field 304 in Figure 3 occupies a bit. The additional field 304 can be used to indicate an initial state of the resources and parameters without concession to be configured by format signaling. The initial state can be active or inactive. For example, as table 30 6 shows, a value (for example, 0) of the additional field 304 is used to indicate the active state and another value (for example, 1) of the additional field 304 is used to indicate the inactive state. If additional field 304 indicates active, it means that resources and parameters without concession can be used immediately, without being activated
Petition 870190116979, of 11/13/2019, p. 59/100
53/87 by additional signaling (for example, layer 1 signaling, DCI) from the base station. If additional field 304 indicates inactive, it means that resources and parameters without concession can only be used when a signaling (for example, layer 1 signaling, DCI) to activate them is received by the UE.
[00125] If the base station uses format A signaling to configure resources and parameters without concession to the UE, the UE performs UL transmission without UL concession using the resources and parameters without concession indicated by the received RRC signaling. In this scenario, resources and parameters without concession can be used by the UE to transmit uplink data without being activated by layer 1 signaling, such as DCI. In other words, the resources and parameters without concession configured by format A RRC signaling are active.
[00126] If the base station uses a format B RRC signaling to configure resources and parameters without concession for the UE, the UE configures the resources and parameters without concession based on the RRC signaling, and the configured resources and parameters without concession can be configured. subject to additional signaling (eg, Layer 1 signaling, DCI signaling, RRC) from the base station. The additional signaling can be used to activate, deactivate, modify or release at least part of the resources and parameters without concession. When additional signaling is used to influence the state of part of the resources and parameters without concession, the additional signaling may comprise information indicating which part of the resources and parameters without concession needs to be enabled, disabled,
Petition 870190116979, of 11/13/2019, p. 60/100
54/87 modified or released. Additional signaling (eg, layer 1 signaling, DCI signaling, RRC) can be used to activate, deactivate, release, update and / or modify at least part of the resources without concession and / or at least part of the parameters without concession.
[00127] In one example, LI signaling can modify at least time and frequency resources, including time-frequency sizes of resource allocation. LI signaling can be sent less frequently than broadcast opportunities without concession. LI signaling can be used in modified or updated parameters including associated transmission parameters, such as RS, MCS, power control, numerology, subband option, etc.
[00128] If the additional field 304 in the RRC signaling indicates the active state, the resources and parameters without concession can be used immediately to transmit uplink data without obtaining the UL concession. If the additional field 304 in the RRC signaling indicates the inactive state, resources and parameters without concession cannot be used for UL transmission until an additional signaling (for example, layer 1 signaling, RRC signaling) to activate the granting of resources and parameters without concession.
[00129] To keep transmissions stable and without concession with possible reconfiguration of RRC resources and LI signaling for updates of resources and parameters, there is a mechanism to coordinate Ll signaling and RRC reconfiguration to avoid things like signal conflict, both types signaling in the same TTI.
Petition 870190116979, of 11/13/2019, p. 61/100
55/87
In another mode, after a Li signaling for resource changes, the RRC reconfiguration of the resource changes can be ignored if it is too close in time (for example, some TTIs) for Li signaling.
CONFIGURATION AND ENABLING / DISABLING OF BANDWIDTH PART FOR TRANSMISSIONS WITHOUT CONCESSION [00130] A part of bandwidth (BWP) is a part or all of the system bandwidth in a carrier frequency band, which will be allocated to a carrier frequency band. UE for DL or UL transmission. A UE can configure one or more BWPs by RRC signaling, while one or more BWPs can be activated as active BWPs at any given time for a service cell by DCI or RRC signaling; and one or more active BWPs can be deactivated / switched (for example, to a standard active BWP) by DCI signaling, RRC signaling or a timeout.
[00131] For resource configurations without concession, the resources of time and frequency without concession are associated with one or more parts of bandwidth, since the resources of frequency without concession must be allocated in one or more BWPs, as a configuration of the BWP will include bandwidth and local frequency frequency for the BWP. In some embodiments, one or more BWPs can be configured by a dedicated RRC signaling for configuring the bandwidth portion just before configuring GF resources for a UE GF. Thus, the non-concession resources to be configured must be within a BWP and can use the BWP location as a frequency reference to configure resources in the frequency domain without concession; for example, using the BWP departure location (for example,
Petition 870190116979, of 11/13/2019, p. 62/100
56/87 a PRB index) to define the relative frequency location (s) for UE frequency resources without concession in the BWP or, alternatively, using the absolute frequency location (s) (for example , starting number and length of RB in the frequency domain in RBs) for UE frequency resources without concession, so that they are within the BWP. In other embodiments, one or more BWPs for a UE can be configured on the same RRC signaling for the configuration of resources without UE concession, where one or more sets of resources without concession must be placed within one or more BWPs. In some embodiments, the frequency domain allocation parameter for resource configuration without concession can be expanded to include the parameters of one or more BWPs. For example, the expanded frequency domain allocation may include a frequency bandwidth and frequency location of a BWP, numerology and frequency domain locations in relation to the initial BWP location for one or more resource configurations without concession, as well as numerology; expanded frequency domain allocation can also include one or more BWP configurations, each of which includes frequency domain locations associated with one or more resource configurations without concession. In addition, activation and / or deactivation / reconfiguration in the BWP (s) and / or resource configurations without concession can be done using one or more BWP indexes if two or more BWPs (each with a unique BWP index) are configured for the UE. A GF resource configuration can also be carrier-based, where a common relative allocation associated with each BWP for GF resources in the
Petition 870190116979, of 11/13/2019, p. 63/100
57/87 frequency must be defined or configured in the GF resource configuration.
[00132] A UE BWP configuration with one or more BWPs can be configured first and the GF frequency resources in one or more resource configurations can be configured later, each being associated with each of the BWPs. Alternatively, each GF resource configuration can include one or more BWP configurations and associated GF frequency resources and other resources and parameters. In some embodiments, triggering or activating a feature without a concession will also trigger or activate the associated BWP as active BWP (and no additional BWP switch signaling is required); and triggering or activating a BWP as an active BWP will also make one and / or more GF resource configurations allocated in the BWP as active resources and, optionally, for multiple GF resource configurations, one or more signaling messages can be applied to activate the resources of GF resources in a different GF resource configuration. Deactivating a resource without a concession will also deactivate the associated BWP as an inactive BWP (and no additional BWP switch signaling is required); and deactivating a BWP as an inactive BWP will deactivate all GF resource settings allocated in the BWP as inactive resources, and no additional deactivation flags are required to deactivate GF resources in the associated BWP. The signaling scheme above can be RRC and / or DCI.
[00133] For a resource configuration only RRC in transmission without concession, one or more BWPs can be configured by the same RRC signaling for the configuration
Petition 870190116979, of 11/13/2019, p. 64/100
58/87 of resources or an RRC signaling dedicated only to the configuration of the bandwidth portion; one or more BWPs can be activated as active BWP at any given time for a service cell by another dedicated RRC signaling or RRC signaling for the GF resource (re) configuration. In some embodiments, one or more BWP (s) can be defined as active BWP (s) or standard asset (s) in the RRC GF resource (re) configuration only or by a dedicated RRC signaling. If multiple BWPs were previously configured by a dedicated RRC signal other than RRC signaling for GF resource configuration, BWP configurations can include BWP indices, where a BWP index refers to each unique BWP configuration. As a result, a BWP index can be used for the activation and deactivation / switching of BWP (for an active BWP or a standard active BWP). For several GF resource (re) configurations, each GF resource (re) configuration can include the parameters of one or more BWP configurations (or, alternatively, one or more BWP indexes) to configure, enable and / or disable the one or more BWPs, where the GF resources of a GF resource (re) configuration are valid for use only in one or more active BWPs included in the GF resource (re) configuration. Alternatively, the multiple GF resource (re) configurations can share and include the parameters of one or more BWP configurations, where the GF resources of the various GF resource (re) configurations are valid for use in only one or more Active BWPs included in the various (re) configurations of GF resources.
[00134] For a combination of resource configuration
Petition 870190116979, of 11/13/2019, p. 65/100
59/87 of RRC and DCI signaling in transmission without concession, the BWP configuration can be done in RRC or DCI signaling for configuration of GF resources (which includes the reconfiguration, activation, deactivation / release of resources, and / or parameter update, etc.) or can be done in a dedicated RRC or DCI signaling for configuring the bandwidth portion. One or more BWPs (or their BWP configuration indexes refer to BWPs) can be explicitly enabled as active BWPs or defined as standard active BWPs in RRC or DCI signaling for configuring GF resources, or can be made in an RRC signal or DCI dedicated for configuring the bandwidth portion. In addition, an active BWP (or an active BWP index) of a UE can be deactivated or switched by RRC or DCI signaling for configuring GF resources, by a dedicated RRC or DCI signaling for configuring the bandwidth portion or with based on a timer, to another BWP (or BWP index) or other BWPs (or BWP indexes) among the configured BWPs. One or more standard active BWPs can be predefined or preconfigured for a UE by RRC or DCI signaling for configuring GF resources, by a dedicated RRC or DCI signaling for configuring the bandwidth portion. GF resources configured from an RRC or DCI signaling for configuration of GF resources are valid for use only in one or more active BWPs included in RRC or DCI signaling for configuration of GF resources.
[00135] The configuration in a BWP includes numerology (for example, subcarrier spacing and CP length), location of the initial frequency domain and length
Petition 870190116979, of 11/13/2019, p. 66/100
60/87 of the frequency domain (for example, in the number of RBs), optionally signal waveform, etc. A UE is configured with the BWP in terms of PRBs and an offset between the BWP and a reference point (frequency domain) is implicitly or explicitly indicated for the UE, where the reference point can be, for example, center / carrier limit NR, or Common PRB index starting point, such as PRBO.
[00136] The numerology of the UL BWP configuration is applied to at least PUCCH, PUSCH and corresponding DMRS; the numerology of the DL BWP configuration is applied to at least PDCCH, PDSCH and corresponding DMRS.
[00137] The BWP configuration can be UE specific, based on the UE group or cell specific, depending on the scenarios, such as UE connection states (for example, RRC connected, inactive or idle). In some embodiments, a UE in the state connected to the RRC may apply the RRC only for the configuration of GF resources or a combination of RRC and DCI signaling for the configuration of GF resources for the UE-specific BWP configuration and / or activation / deactivation / switching; in the inactive state, the BWP configuration and / or activation / deactivation can be applied by broadcast or multiplexed broadcast signaling for cell-based or group UEs. For GF transmission, configuration, an activation and / or deactivation of parts of the DL and / or UL bandwidth can be done through dedicated RRC signaling or DCI signaling, unlike signaling for GF resource configurations, where activation can be performed in the configuration of the bandwidth part; and if an UE is
Petition 870190116979, of 11/13/2019, p. 67/100
61/87 configured with several BWPs, each with a different BWP configuration index, BWP index / indices can be used for activation or deactivation by EU-specific RRC signaling or DCI signaling.
HARQ AND GF RNTI RETURN DETAILS [00138] A GTTI RNTI, different from concession-based C-RNTI, is configured for a UE (or a group of UEs) for, for example, HARQ return and concession-based retransmission UL (GF2GB switching), and feature activation / deactivation, parameter update, as well as UL data scrambling or CRC scrambling, etc. To return HARQ in the identification of a TB HARQ process ID from a UE, the base station must detect the UE, for example, DMRS / RS specific to UL UE / TB. If the RS and the data have been successfully decoded, the GF RNTI can be used to confirm the TB of the UE through the UL grant with the TB process ID HARQ, RS and / or NDI (for example, 0); or group the common PDCCH to obtain a list of information for the group of UEs, each in the list with a bitmap to indicate a bit value (for example, for yes in this case), which TB in which frequency resources and / or which RS.
[00139] In case the RS has been successfully decoded, but the data does not present a detection failure, the GF RNTI can be used to negatively confirm the TB of the UE through the UL grant with the process ID TB HARQ, RS and / or NDI (for example, 1); or group the common PDCCH to obtain a list of information for the group of UEs, each in the list with a bitmap to indicate a bit value (for example, not in this case), which TB in which resources
Petition 870190116979, of 11/13/2019, p. 68/100
62/87 frequency and / or which RS. In some embodiments, RS (s) with an optional frequency-time frequency can be used to indicate NACK for failure to detect data from one or more UEs / TBs.
INITIAL TRANSMISSION IDENTIFICATION [00140] For transmissions without concession, EU traffic can arrive at any time, but the initial transmission time must be detected or identified, so that HARQ operations, such as HARQ process ID, redundant version number can work. To identify the initial transmission time when traffic arrives, different schemes can be used for this. For example, the GF transmission to a TB may take different DMRSs (or cyclic RS shifts) for its initial transmission and subsequent transmissions. In another modality, some special frequency-time resources can be used for initial transmissions, for example, initial transmissions can be performed at certain times and / or pre-defined or pre-configured frequency resources. A combination of time, frequency and / or RS can also be used to identify initial transmission time.
GF CONFIGURATION WITH MINI-INTERVAL [00141] For the configuration of resources only RRC in GF transmission, the UE and gigabit nodeB (gNB) need to have the same knowledge of what the frame structure configured in TDD is like, for example, several range types: DL only, UL only, UL, DL centered and UL centered; or self-contained interval: starting from downlink control and ending with uplink control at an interval with fast SRS / CQI and timing
Petition 870190116979, of 11/13/2019, p. 69/100
63/87
Flexible HARQ; as well as the configured mini-range allocations (each with initial symbol position and duration) in a range, for example, where and how many 2-symbol mini-intervals are allocated in the 7-symbol interval or mini-interval for DL, UL, or both links in the range. The configuration can be semi-static, for example, a common group PDCCH subframe information message. For transmissions without concession with a combination of RRC and DCI signaling, it is possible to support static and / or semi-static signaling configurations. In addition, the frame structure and the mini interval setting can also be applied to the FDD.
[00142] The configuration of the time domain resource without concession can apply a periodicity parameter, where the periodicity can be used to define the transmission occasions without concession for initial and repetitions explicitly or to explicitly define only the initial transmission occasions without concession while transmission times for subsequent repetitions are defined implicitly, such as grouping as LTE. In other modalities, the time domain resource configuration without concession can apply two periodicity parameters, where, explicitly, one periodicity defines the transmission times without concession for initial transmissions and the other defines the transmission times without concession for the repetitions subsequent A periodicity parameter can indicate absolute time units, such as how many intervals between two neighboring transmission resources can be configured by periodicity for an FDD; a periodicity parameter can indicate (or count) the number of
Petition 870190116979, of 11/13/2019, p. 70/100
64/87 units of basic resources available, such as how many mini-intervals between two neighboring transmission resource occasions must be configured by frequency for a TDD.
[00143] Given the configured GF transmission occasions, an initial TB transmission can be performed on a fixed transmission occasion, can be performed on any transmission occasion or can be configurable (one of two options) to operate the initial transmissions ( Option 1) on transmission occasions or (Option 2) any transmission occasions, by static / RRC or dynamic / DCI signaling. In one mode, which option to be configured for initial transmissions can be based on certain considerations, such as types / requirements of application / service. For Option 2 configuration, the initial transmission time for, for example, HARQ ID determination, RV sequence number determination, etc., different schemes can be determined in the ways described in the previous paragraphs.
CONFIGURATION OF PUSCH AND UL CONTROL RESOURCES [00144] For physical uplink shared channel (PUSCH) and / or UL control feature configuration on UL transmission without a dynamic concession and / or concession based transmission, and the (s) interval-based and / or non-interval-based scenario (s), the following formula can be used to determine resource and transmission times for one or more UEs:
L 14 (10 (Tly - 0) 2 + 7l _s ) + V-symbol ~ ^ symbol_d.eslaca.da J TTlod P - 0 [00145] In the formula above, the LYJ operator indicates the largest integer less than or equal to X. n is a number of

65/87 system frame, or index, in the system (from 0), 0 is an offset relative to the start of the system radio frame (ie SFN # 0), and each frame consists of 10 sub frames 1 ms. u is an integer indicating the configuration of a numerology in terms of sub carrier spacing option (for example, 0, 1, 2 and 3 for 15kHz, 30kHz, 60kHz and 120kHz), where 15kHz is used as a spacing option subcarriers with u = 0. n _s is an interval index within a system frame, starting from 0 to 140 2 ^U - 1, for a given numerological configuration of u. Ti is _the i _slmbo within a symbol interval starting from 0 to 13. _{Chakra symbols} n i i _{odes Ocado} is a (pre) configured, for example, by the RRC or, equivalently, LI signaling or default symbol offset within a interval. For an interval-based configuration, ⁿ displaced_symbo can be zero by default, and for a non-interval-based configuration 'displaced risimbus can be zero or a positive integer, for example, from 1 to 13. P is the resource periodicity in terms of the number of symbols (or in intervals or time units), indicating a distance in time, for example, in number of symbols, between two neighboring occasions of PUSCH resource or control channel between periodic and repeated resources.
[00146] In addition, when O is defined by an offset in terms of the number of subframe numbers since the beginning of a system radio frame, and the other parameters are kept the same as described in the paragraph above, one can use the following formula to determine resource and transmission times:

CONFIGURATION OF RESOURCES WITHOUT CONCESSION OPTION H [00147] Compared to options A-F, this option differs from them only in that Fl and F2 in RRC signaling have been replaced by a field and the other part is the same with options A-F. This field can have several values, different values indicate different state of the resources and parameters without concession. For example, the field can occupy two bits. When the field has a value of 00, it means that the UL transmission without concession can be performed by a UE using the resources and parameters without concession, after the semi-static configuration (without any further activation of Ll / DCI), which at least can be used for configuring URLLC applications and services and cannot be disabled and / or updated and / or modified or released by an LI signal. When the field has a value of 10, it means that resources and parameters without concession need to be activated using another signal from the base station and can also be modified or updated, released by another signal. When the field has a value of 11, it means that resources and parameters without concession can be used without being additionally activated and can be deactivated, modified, updated or released by other signaling.
SOME MORE DETAILED DESCRIPTIONS ON TRANSMISSION MODES WITHOUT CONCESSION [00148] There are multiple transmission options without concession to configure associated resources and parameters and operate in different ways, and the UE and gNB can follow different operational behaviors.
[00149] Option 1 defines and includes two modes of data transmission free of scheduling request
Petition 870190116979, of 11/13/2019, p. 73/100
67/87 (SR) UL: mode A and mode B. Free of SR means that there is no scheduling request.
[00150] In mode A, with reference to Figure 4A, the base station 170 configures (404) resources and transmission parameters through RRC signaling for the UE 110, the UE does not need (406) (periodically, for example, all TTI ) monitor PDCCH lease information (eg DCI), including enable / disable / release signaling, transmission parameter update signaling, the UE may or may not need to detect ACK signaling (ACK early termination, transmission times predefined without ACK), the activation, deactivation or release of resources without concession is made by one or more control messages of more bits through RRC signaling. Since there is UL data that needs to be transmitted, the UE applies at least part of the resources and parameters configured through RRC signaling to transmit (408) the UL data without obtaining a UL grant. In this mode, RRC signaling will be used to handle all resource configuration and reconfiguration, so that no DCI signaling is used in this case.
[00151] In mode B, referring to Figure 4B, the base station 170 configures (404) transmission parameters and resources through RRC signaling for UE 110, but the configured transmission parameters and resources cannot be used to transmit UL data until that the LI activation signal (for example, through PDCCH) to activate at least part of the features and parameters is received; the UE needs to monitor (412) DCI in each TTI for possible changes in the transmission parameters; if it is a signage (414)
Petition 870190116979, of 11/13/2019, p. 74/100
68/87 to disable at least part of the resources and parameters without concession that were monitored in step 412, the UE can stop using the part of the configured resources and parameters without concession; if it is a DCI grant signal that is received in step 412, the UE can switch to grant based transmission. Since there is UL data needed to be transmitted, the UE implements step 408.
[00152] In option 2, the resources and parameters of free SR transmission are configured by the RRC signaling, in which an additional indicator is used to indicate whether the Ll / DCI signaling is used or not for the activation, deactivation / release and modifications of parameters, etc., so we have modes: Mode C (DCI disabled mode) and Mode D (DCI enabled mode). The mode type can be pre-defined or pre-configured by RRC signaling.
[00153] In mode C, with reference to Figure 4C, base station 170 configures (416) resources and parameters without concession through RRC signaling for UE 110, in which RRC signaling includes an indicator to indicate that DCI is not necessary for activate resources and parameters without concession, the UE does not (406) (periodically, for example, all TTI) monitor PDCCH grant information (for example, DCI), including activation / deactivation / release signaling, update signaling transmission parameter, the UE may or may not need to detect the ACK signaling (early termination with ACK, predefined transmission times without ACK), the activation, deactivation or release of the resource without concession is done by a control message of one or more bits through RRC signaling. When there is a need to transmit
Petition 870190116979, of 11/13/2019, p. 75/100
69/87 UL data, the UE applies at least part of the resources and parameters configured through RRC signaling to transmit (408) the UL data without obtaining a UL concession. In this mode, RRC signaling will be used to handle all configurations and resource reconfigurations. As a result, no DCI signaling is used in this case and the UE may or may not monitor, in each TTI, the LI signaling as PDCCH, which can be configured by gNB based on the EU capacity report.
[00154] In D mode, with reference to Figure 4D, the base station 170 configures (418) resources and transmission parameters via RRC signaling for UE 110, but the RRC signaling includes an indicator to indicate that the transmission resources and parameters configured cannot be used to transmit UL data until the LI activation signal (for example through the PDCCH) to activate at least part of the received resources and parameters; the UE needs to monitor (420) DCI in each TTI for possible changes in the transmission parameters; if it is a signal (422) to disable at least part of the non-concession resources and parameters that were monitored in step 420, the UE can stop using the configured non-concession resources and parameters part; if it is DCI concession signaling that is received in step 940, the UE can switch to concession based transmission. Since there is UL data needed to be transmitted, the UE implements step 408.
[00155] The UE can report (402) its UE capacity, such as type of traffic / service, type of device, mobility, etc. to the base station. The base station can decide which transmission option without a concession or which mode
Petition 870190116979, of 11/13/2019, p. 76/100
70/87 is used based on the reported capacity of the UE. The base station and the UE can support one or more of the modes mentioned above.
[00156] Figure 5 illustrates an exemplary flowchart of a 500 method method for two UEs to configure resources for transmission without concession. Method 500 starts at step 502, where a first UE receives a first RRC signal from a base station. The first RRC signal can specify a first subset of configuration parameters for transmission without concession to the first UE. In one embodiment, the first subset of the configuration parameters specified by the first RRC signal may comprise periodicity of resources for transmission without concession. The first UE can be UE1 in Figure 2.
[00157] In step 504 of Figure 5, the first UE receives a first DCI signal from the base station. The first DCI signal can specify a second subset of the configuration parameters for transmission without concession to the first UE. In one embodiment, the second subset of the configuration parameters specified by the first DCI signal can include one or more UL time / frequency resources reserved for transmission without concession, a modulation and coding scheme (MCS) parameter for transmission without concession and a configuration of the demodulation reference signal (DMRS) for transmission without concession.
[00158] In step 506, the first UE can perform a first transmission without concession according to the configuration parameters for transmission without concession on the first RRC signal and the first DCI signal. In one embodiment, the first UE can execute the first
Petition 870190116979, of 11/13/2019, p. 77/100
71/87 UL transmission without concession, according to the first subset of configuration parameters for transmission without concession specified in the first RRC signal and the second subset of configuration parameters for transmission without concession specified in the first DCI signal.
[00159] In step 512, a second UE receives a second RRC signal from the base station. The second RRC signal can specify one or more configuration parameters for transmission without concession. In one embodiment, the second RRC signal may include one or more uplink frequency (UL) resources reserved for transmission without concession, start time reference, resource periodicity, a time resource size parameter for transmission without concession , a modulation and coding scheme (MCS) parameter for transmission without concession, a demodulation reference signal (DMRS) configuration for transmission without concession, power control parameters and one or more repetition factors for transmission without concession. In the second RRC signal, the time resource size parameter for transmission without concession can include an accessible start position and an accessible end position of a data transmission interval (TTI). TTI data can be one of a symbol, a mini-interval and an interval. Mini-gap terminology can also be referred to as non-gap. The TTI here is also applicable to the transmission of any uplink (UL) and / or downlink (DL) control information. The second UE can be UE2 in Figure 2.
[00160] In addition, the one or more second UE configuration parameters specified by the second RRC signal can
Petition 870190116979, of 11/13/2019, p. 78/100
72/87 include transmission numerology for transmission without concession, subband division and subband locations. In one embodiment, transmission numerology for transmission without concession, subband division and subband locations are preconfigured by explicit or implicit broadcast signaling. In another modality, the transmission numerology for transmission without concession, the subband division and the subband locations can be pre-configured by RRC signaling.
[00161] In some embodiments, the one or more second UE configuration parameters of the second RRC signal may specify one or more parts of bandwidth to be activated as one or more parts of bandwidth active or to be defined as one or more standard active bandwidth parts in a service cell.
[00162] In step 514 of Figure 5, the second UE can perform a second UL transmission without concession according to the configuration parameters for transmission without concession specified by the second RRC signal. In one embodiment, DCI signaling is not necessary for configuring resources for the second UE. Thus, with the second RRC received, the second UE can perform the second UL transmission without concession, without waiting for a DCI signal.
[00163] In some modalities, at least one of the first and second RRC signals can comprise information indicating one of at least two predefined resource configuration options for UL transmission without concession. The first default resource configuration option can be a combination of RRC configuration and DCI / Layer 1 signaling. The first RRC signal received by the first UE can indicate
Petition 870190116979, of 11/13/2019, p. 79/100
73/87 that the first UE is receiving a combination of RRC configuration and DCI / Layer 1 signaling configuration. The second default transmission resource configuration option may be configuration based on non-DCI signaling (for example, RRC signaling) . The second RRC signal received by the second UE may indicate that the second UE is receiving a configuration based on non-DCI signaling.
[00164] For configuration based on non-DCI signaling, a UE can receive updates of configuration parameters on an RRC signal or a DCI signal from the base station. For example, the second UE may receive a third RRC signal comprising information to update one or more configuration parameters for transmission without concession specified by the second RRC signal. In another example, the second UE can receive a second DCI signal specifying information to update one or more configuration parameters for transmission without concession specified by the second RRC signal. After receiving the updates, the second UE can perform a UL transmission without a concession, according to one or more configuration parameters updated for transmission without a concession.
[00165] In one embodiment, a UE can use the configuration parameters for transmission without concession to perform data transmission without concession or to control message transmission without concession. For example, the first UE can perform the first UL transmission without concession, according to the first and the second subset of configuration parameters for transmission without concession, and the first UL transmission without concession can be data transmission, message transmission. control

In another example, the first UE can perform the second UL transmission without concession, according to the one or more configuration parameters for transmission without concession specified by the second RRC signal, and the second UL transmission without concession can be data transmission, transmission control message, or a combination of both.
[00166] In one mode, when in an idle or idle state, the first UE can receive a broadcast signal specifying one or more configuration parameters for transmission without granting the base station. The one or more configuration parameters for broadcast without concession may include at least one of the UL frequency resources reserved for transmission without concession, start time reference, resource periodicity, a time resource size parameter for transmission without concession, a modulation and coding scheme (MCS) parameter for transmission without concession, a demodulation reference signal configuration (DMRS) for transmission without concession, power control parameters and one or more repetition factors for transmission without concession. The first UE can then perform a UL transmission according to one or more configuration parameters for transmission without concession specified by the broadcast signal.

The second UE can then perform a UL transmission according to one or more configuration parameters for transmission without concession specified by the multiplexed broadcast signal.
[00170] Figure 6 illustrates an exemplary flow chart of a method of modality 600 for a base station to configure transmission resources for transmission without concession. Method 600 starts at step 602, where the base station transmits a first radio resource control (RRC) signal to a first UE. The first RRC signal can specify a first subset of the first UE configuration parameters.

The second subset of the first UE configuration parameters for transmission without concession can comprise one or more UL time / frequency resources reserved for transmission without concession, a modulation and coding scheme (MCS) parameter for transmission without concession and a configuration of demodulation reference signal (DMRS) for transmission without concession.
[00172] In step 606, the base station can receive, from the first UE, a first UL transmission without concession according to the configuration parameters for transmission without concession on the first RRC signal and the first DCI signal. In one embodiment, the base station can receive the first UL transmission without concession, according to the first subset of configuration parameters for transmission without concession specified in the first RRC signal and the second subset of configuration parameters for transmission without concession specified in the first DCI signal.

In the second RRC signal, the time resource size parameter for transmission without concession can include an accessible start position and an accessible end position of a data transmission interval (TTI). TTI data can be one of a symbol, a mini-range and a range. Mini-gap terminology can also be referred to as non-gap. The TTI here is also applicable to the transmission of any uplink (UL) and / or downlink (DL) control information.
[00174] In step 614, the base station can receive, from the second UE, a second UL transmission without concession, according to the configuration parameters for transmission without concession in the second RRC signal. In one embodiment, DCI signaling is not necessary for configuring resources for the second UE. Thus, with the second RRC transmitted, the base station can receive, from the second UE, the second UL transmission without concession, without waiting for the transmission of a DCI signal to the second UE.
[00175] In some modalities, at least one of the first and second RRC signals can comprise information indicating one of at least two predefined resource configuration options for UL transmission without concession. The first transmission configuration option can be a combination of RRC configuration and DCI / Layer 1 signaling.

79/87 UL transmission feature configuration option can be configuration based on non-DCI signaling (for example, RRC signaling). The second RRC signal transmitted by the base station may indicate that the second UE is receiving a configuration based on non-DCI signaling.
[00176] For configuration based on non-DCI signaling, a base station can transmit updates of configuration parameters on an RRC signal or a DCI signal to a UE. For example, the base station can transmit to the second UE a third RRC signal comprising information to update one or more configuration parameters for transmission without concession specified by the second RRC signal. In another example, the base station may transmit, to the second UE, a second DCI signal specifying information to update one or more configuration parameters for transmission without concession specified by the second RRC signal. After transmitting the updates, the base station can receive a UL transmission without a concession, according to one or more configuration parameters updated for transmission without a concession.
