COMMUNICATION INDICATION CHANNEL PROJECTS
ULTRACUSTIBLE LOW LATENCY
CROSS REFERENCE WITH RELATED APPLICATION (S) [0001] This application claims the benefit of US Provisional Patent Application No. 62 / 470,075, called ULTRA-REALTABLE LOW LATENCY COMMUNICATION INDICATION CHANNELIZATION PROJECTS and filed on March 10, 2017 and the Application for US Patent No. 15 / 917,566, called ULTRA-REALIBLE LOW LATENCY COMMUNICATION INDICATION CHANNELIZATION PROJECTS and filed on March 9, 2018, which are expressly incorporated by reference in their entirety.
BACKGROUND
Technical Field [0002] The present disclosure generally relates to communication systems, and more particularly, to systems, methods and devices that provide an indication of an occurrence of ultra-reliable low-latency communication.
Introduction [0003] Non-wired communication systems are widely implemented to provide various telecommunication services, such as telephony, video, data, messaging and broadcasts. Typical non-wired communication systems can employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access systems
Petition 870190087199, of 9/5/2019, p. 7/130
2/88 (TDMA), frequency division multiple access systems (FDMA), orthogonal frequency division multiple access systems (OFDMA), single carrier frequency division multiple access systems (SCFDMA) and access systems time division code multiple (TD-SCDMA).
[0004] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that allows different non-wired devices to communicate at the municipal, national, regional and even global levels. An example of a telecommunication standard is Nova Rádio (NR) 5G. 5G NR is part of an evolution of mobile broadband continues promulgated by the Third Generation Partnership Project (3GPP) to meet the new requirements associated with latency, reliability, security, scalability (for example, with Internet-of-Things (IoT )) and other requirements. Some aspects of NR 5G may be based on the 4G Long Term Evolution (LTE) standard. There is a need for further improvements in the 5G NR technology. These enhancements may also apply to other multiple access technologies and to telecommunication standards employing those technologies.
[0005] In some circumstances, an ultra-reliable low-latency communication (URLLC) can appropriate or puncture resources occupied, for example, by an enhanced mobile broadband communication (eMBB) in progress. Therefore, some devices may send a URLLC indicator indicating that the URLLC data is within eMBB data. Others
Petition 870190087199, of 9/5/2019, p. 8/130
3/88 devices can receive a URLLC indicator indicating that the URLLC data is within eMBB data.
SUMMARY [0006] The following statement presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not a comprehensive overview of all aspects covered, and is not intended to identify the key elements or critical elements of all aspects, nor to outline the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified way, as a prelude to the more detailed description presented later.
[0007] As discussed above, in some circumstances, a URLLC may appropriate or puncture a busy resource, for example, an eMBB communication in progress. For example, URLLC can replace a portion of the eMBB data, for example, in the ongoing eMBB communication. In an alternative example, URLLC data can be sent at the same time as a part of the eMBB data, puncturing the part of the eMBB data, in the ongoing eMBB communication.
[0008] Consequently, some devices (for example, a base station or an UE) may send a URLLC indicator indicating that the URLLC data is sent over shared channel resources, which may include eMBB data. Other devices (for example, a UE or a base station) can receive a URLLC indicator indicating that the URLLC data is sent on the shared channel and can puncture or appropriate the eMBB data.

4/88 [0009] In one aspect of the disclosure, a method, a computer-readable medium and an apparatus are provided. The apparatus may be a base station configured to generate a set of resource blocks including at least one of eMBB data or URLLC data on a shared physical downlink channel (PDSCH). The base station can be configured to generate a URLLC indicator indicating whether the set of resource blocks includes at least part of the URLLC data. The base station can be configured to send, to at least one user device (UE), the URLLC indicator and the set of resource blocks including at least one of the eMBB data or the URLLC data. The URLLC indicator being sent embedded in the URLLC data or sent separately from the URLLC data within the downlink control (DCI) information of a physical downlink control channel (PDCCH).
[0010] In another aspect of the disclosure, a method, a computer-readable medium and an apparatus are provided. The apparatus may be a UE configured to receive a set of resource blocks from a base station comprising at least one of the eMBB data or URLLC data in a PDSCH. The UE can be configured to receive a URLLC indicator from the base station. The URLLC indicator can be received embedded with the URLLC data or be received separately from the URLLC data within the DCI of one of a PDCCH. The URLLC indicator can indicate whether the resource block set includes URLLC data. The UE can be configured to determine, based on the URLLC indicator, whether the set of resource blocks includes URLLC data. The UE can be configured to process,

5/88 based on the URLLC indicator, the set of resource blocks received including at least one of the eMBB data or URLLC data.
[0011] In another aspect of the disclosure, a method, a computer-readable medium and an apparatus are provided. The device can be a UE configured to generate a set of resource blocks, including URLLC data, generate a URLLC indicator in a DCI message common to a group, indicating that the URLLC data is in a subset of the resource block set and is inside the PUSCH for eMBB data, and send the URLLC indicator and the set of resource blocks, including URLLC data, to a base station.
[0012] In another aspect of the disclosure, a method, a computer-readable medium and an apparatus are provided. The apparatus may be a base station configured to receive a set of resource blocks from a UE. The UE can also be configured to receive a base station URLLC (gNB) indicator. In addition, the UE can be configured to determine, based on the URLLC indicator, that a subset of the resource block set includes or does not include URLLC data.
[0013] In another aspect of the disclosure, a method, a computer-readable medium and an apparatus are provided. The apparatus may be a UE configured to transmit, to a base station, a URLLC indicator indicating a set of uplink URLLC (UL) resources for transmitting URLLC data. The UE can also be configured to generate a set of resource blocks, including URLLC data. Additionally, the UE can be configured

6/88 to send to the base station the set of resource blocks including URLLC data within the indicated UL URLLC resource set.
[0014] For the accomplishment of the previous and related purposes, one or more aspects comprise the characteristics described completely and particularly highlighted in the claims of this document. The following description and the accompanying drawings set out in detail some illustrative features of one or more aspects. However, these characteristics are indicative of just a few of the various ways in which the principles of various aspects can be employed, and this description is intended to include all of these aspects and their equivalents.

DETAILED DESCRIPTION [0040] The detailed description set out below in connection with the accompanying drawings is intended as a description of various configurations and is not intended to represent only the only configurations in which the concepts described in this document can be practiced. The detailed description includes specific details for the purpose of providing a complete understanding of various concepts. However, it will be evident to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known structures and components are
Petition 870190087199, of 9/5/2019, p. 14/130
9/88 presented in the form of a block diagram in order to avoid obscuring such concepts.
[0041] Various aspects of telecommunication systems will now be presented with reference to various devices and methods. These devices and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as elements). These elements can be implemented using electronic hardware, computer software or any combination of these. Whether these elements are implemented as hardware or software depends on the particular application and the design restrictions imposed on the system as a whole.
[0042] By way of example, an element, or any part of an element, or any combination of elements can be implemented as a processing system, which includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems in a chip (SoC), baseband processors, field programmable port arrays (FPGAs), programmable logic devices (PLDs), state machines, port logic, discrete hardware circuits, and other suitable hardware configured to perform the various features described throughout this revelation. One or more processors in the
Petition 870190087199, of 9/5/2019, p. 15/130
10/88 processing can run the software. The software should be interpreted broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, execution threads, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language or otherwise.
[0043] Therefore, in one or more illustrative embodiments, the functions described can be implemented in hardware, software or any combination thereof. If implemented in software, functions can be stored or encoded as one or more instructions or as code in a computer-readable medium. Computer readable media includes computer storage media. The storage media can be any available media that can be accessed by a computer. By way of example, and not by way of limitation, such computer-readable media may comprise a random access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), an optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the types of computer-readable media mentioned above, or any other medium that can be used to store executable computer code in the form of instructions or data structures that can be accessed by a computer.

11/88 [0044] Several aspects of the systems and methods described in this document relate to uplink or downlink indications. Uplink or downlink indications can be URLLC indications, that is, a URLLC indicator. Therefore, in some respects, the URLLC indicator may be an uplink URLLC indicator, and in other respects, the URLLC indicator may be a downlink URLL indicator. The downlink indicator can be transmitted from a base station to a UE. The uplink indicator can be transmitted from a UE to a base station. In one respect, a downlink indicator can be in the DCI of a common group PDCCH. A downlink indicator can be a later indication, for example, appearing at the beginning of a next partition. In addition, a downlink indicator can be configured to be a broadband indication or a subband indication (for example, up to 2 sub-bands). For example, the downlink indicator may indicate that a URLCC will appropriate or puncture an entire band, which can be referred to as broadband or if it appropriates or punctures a subband, which can be referred to as a subband. In some cases, the downlink indicator may indicate that a URLCC will appropriate or puncture an entire band, while the actual data sent may not occupy the entire band. In addition, a downlink indicator can be configured to indicate one or more symbols, by configuring the monitoring periodicity. In one respect, an uplink indicator can use one or more of the formats described in this document with respect to downlink indicators. In some respects, an indicator
Petition 870190087199, of 9/5/2019, p. 17/130
12/88 downlink can be a current indication, for example, appearing in the same symbols or mini partitions as the URLLC data. In one example, the indicator can be embedded in the URLLC data. In another example, the indicator can be separated from URLLC data. In some respects, a downlink indicator can be a pre-indication, for example, appearing before URLLC data. In one example, the indicator can be transmitted at the beginning of the partition, for example, in the DCI of a common group PDCCH followed by the URLLC data.
[0045] FIG. 1 is a diagram illustrating an example of a non-wired communications system and an access network 100. The non-wired communications system (also referred to as an unwired wide area network (WWAN)) includes base stations 102, UEs 104 and an Evolved Packet Core (EPC) 160. Base stations 102 may include macro cells (high power cell base station) and / or small cells (low power cell base station). Macro cells include base stations. Small cells include femto cells, pico cells and micro cells.
[0046] Base stations 102 (collectively referred to as the Terrestrial Radio Access Network of the Universal Mobile Telecommunications System (UMTS) Evolved (E-UTRAN)) interface with the EPC 160 through return transport channel links 132 (e.g., Sl interface). In addition to other functions, base stations 102 can perform one or more of the following functions: user data transfer, radio channel encoding and decoding, data protection
Petition 870190087199, of 9/5/2019, p. 18/130
13/88 integrity, header compression, mobility control functions (for example, perform handover, dual connectivity) interference coordination between cells, connection configuration and release, load balancing, distribution for stratum messages that are not accessible (NAS), NAS node selection, synchronization, radio access network (RAN) sharing, multimedia multicast / broadcast service (MBMS), equipment and subscriber tracking, RAN information management (RIM), paging, positioning and distribution of warning messages. Base stations 102 can communicate directly or indirectly (for example, via EPC 160) with each other via return transport channel links 134 (for example, interface X2). The return transport channel links 134 can be wired or non-wired.
[0047] Base stations 102 can communicate in a non-wired manner with UEs 104. Each of base stations 102 can provide communication coverage for a respective geographical coverage area 110. There may be overlapping geographical coverage areas 110. For example, small cell 102 'may have a coverage area 110' that overlaps coverage area 110 of one or more macro base stations 102. A network that includes small cells and macro cells may be known as a network heterogeneous. A heterogeneous network can also include the evolved Home Node B (eNBs) (HeNBs), which can provide service to a restricted group known as a closed group of subscribers (CSG). Communication links 120 between base stations 102 and
Petition 870190087199, of 9/5/2019, p. 19/130
14/88
UEs 104 may include uplink (UL) transmissions (also referred to as reverse link) from UE 104 to a base station 102 and / or downlink (DL) transmissions (also referred to as direct link) from a base station 102 for a UE 104. Communication links 120 can use multi-input and multi-output antenna (MIMO) technology, including spatial multiplexing, beam conformation and / or transmission diversity. Communication links can exist through one or more carriers. Base stations 102 / UEs 104 can use the spectrum up to Y MHz (for example, 5, 10, 15, 20, 100 MHz) of bandwidth per carrier allocated in an aggregation of carriers up to a total of Yx MHz (x carriers components) used for transmission in each direction. The carriers may or may not be adjacent to each other. The allocation of carriers can be asymmetric in relation to DL and UL (for example, more or less component carriers can be allocated to DL than to UL). Component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier can be referred to as a primary cell (PCell) and a secondary component carrier can be referred to as a secondary cell (SCell).
[0048] Some UEs 104 can communicate with each other using the device-to-device (D2D) 192 communication link. The D2D 192 communication link can use the DL / UL WWAN spectrum. The D2D 192 communication link can use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel
Petition 870190087199, of 9/5/2019, p. 20/130
15/88 (PSDCH), a shared physical sidelink channel (PSSCH) and a physical sidelink control channel (PSCCH). The D2D communication link can exist through several D2D non-wired communication systems, such as, for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11, LTE or NR standard.
[0049] The non-wired communications system may additionally include a Wi-Fi access point (AP) 150 in communication with Wi-Fi stations (STASs) 152 via communication links 154 in an unlicensed frequency spectrum of 5 GHz. When communicating over an unlicensed frequency spectrum, STAs 152 / AP 150 can perform a clear channel assessment (CCA) before communicating, in order to determine if the channel is available.
[0050] Small cell 102 'can operate on a licensed and / or unlicensed frequency spectrum. When operating on an unlicensed frequency spectrum, small cell 102 'can employ NR and use the same unlicensed 5 GHz frequency spectrum as used by Wi-Fi AP 150. Small cell 102' employing NR on a spectrum of frequencies not
licensed, can increase roof and / or increase The capacity from the Web in access.[ 0051] 0 gNodeB (gNB) 180 can operate in frequencies wave millimeter (mmW) and / or close in frequencies mmW in Communication as EU 1 04. When the gNB
180 operates at mmW frequencies or close to mmW, the gNB 180 can be referred to as an mmW base station. Extremely high frequencies (EHF) are part of the RF in the
Petition 870190087199, of 9/5/2019, p. 21/130
16/88 electromagnetic spectrum. The EHF has a range of 30 GHz up to 300 GHz and a wavelength between 1 millimeter and 10 millimeters. The radio waves in the band can be called millimeter waves. The nearby mmW can extend up to a frequency of 3 GHz with a wavelength of 100 mm. The super high frequency band (SHF) extends between 3 GHz and 30 GHz, also known as centimeter wave. Communications using the nearby mmW / mmW radio frequency band have an extremely high loss of travel and a short range. The mmWM 180 base station can use beamform 184 with UE 104 to compensate for extremely high travel loss and short range.
[0052] EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Server Gateway 166, a Multicast / Multimedia Broadcast Service Gateway (MBMS) 168, a Multicast Service Center / Broadcast (BM-SC) 170, and a Packet Data Network Gateway (PDN) 172. MME 162 may be in communication with a Home Subscriber Server (HSS) 174. MME 162 is the control node that processes the signaling between UEs 104 and EPC 160. MME 162 generally provides carrier and connection management. All user Internet Protocol (IP) packets are transferred through Gateway Server 166, which in turn is connected to Gateway PDN 172. Gateway PDN 172 provides allocation of UE IP addresses, as well as other functions. Gateway PDN 172 and BM-SC 170 are connected with IP Services 176. IP Services 176 may include the Internet, an intranet, a Subsystem
Petition 870190087199, of 9/5/2019, p. 22/130
17/88 IP Multimedia (IMS), a PS Streaming Service (PSS) and / or other IP Services. The BM-SC 170 can provide functions for providing and delivering MBMS user services. The BM-SC 170 can serve as an entry point for the transmission of the MBMS content provider, can be used to authorize and start MBMS Carrier Services within a public land mobile network (PLMN) and can be used to schedule transmissions of MBMS. The MBMS 168 Gateway can be used to distribute MBMS traffic to base stations 102 belonging to a Broadcast / Multicast Single Frequency Network (MBSFN) area broadcasting a particular service and may be responsible for session management (start / stop) and for collecting loading information related to eMBMS.
[0053] The base station can also be termed as a gNB, Node B, evolved Node B (eNB), an access point, a base transceiver station, a base radio station, a radio transceiver, a transceiver function, a basic set services (BSS), a set of extended services (ESS) or some other suitable terminology. Base station 102 provides an access point for EPC 160 for a UE 104. Examples of UEs 104 include a cell phone, a smartphone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant ( PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (for example, MP3 player), a camera, a game console, a tablet, a device smart one
Petition 870190087199, of 9/5/2019, p. 23/130
18/88 wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a health care device, an implant, a video or any other similar operating device. Some of the UEs 104 can be referred to as loT devices (for example, the parking meter, gas pump, toaster, vehicles, heart rate monitor, etc.). UE 104 can also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, an un-wired unit, a remote unit, a mobile device, an un-wired device, a non-wired communication, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, an un-wired terminal, a remote terminal, a handset, a user agent, a mobile client, a customer or some other terminology proper.
[0054] Referring again to FIG. 1, in some respects, base station 102 can be configured to generate a set of resource blocks including at least one of eMBB data or URLLC data in a PDSCH. Base station 102 can also be configured to generate a URLLC indicator indicating whether the set of resource blocks includes at least part of the URLLC data. Additionally, base station 102 can be configured to send the URLLC indicator and the set of resource blocks to at least one user device (UE) including at least one of the eMBB data or URLLC data, the URLLC indicator being sent embedded within the URLLC data or being sent separately from the URLLC data
Petition 870190087199, of 9/5/2019, p. 24/130
19/88 in the downlink control information (DCI) of a physical downlink control channel (PDCCH) (198).
Consequently, the UE 104 can be configured to receive a set of resource blocks from a base station comprising at least one of the eMBB data or the URLLC data in a PDSCH. UE 104 can also be configured to receive a URLLC indicator from the base station, the URLLC indicator being received and embedded within the URLLC data or being received separate from the URLLC data in the DCI of a PDCCH, the URLLC indicator indicating whether the set of resource blocks includes at least part of the URLLC data. When URLLC data is incorporated into eMBB data, URLLC can take over eMBB transmissions on the same resources, so that only URLLC data is transmitted on the embedded resource and eMBB transmissions are omitted or canceled. Additionally, UE 104 can determine based on the URLLC indicator, whether the resource block set includes URLLC data and process the resource block set based on a result of determining whether the resource block set includes URLLC data (199 ).
[0056] From the perspective of a URLLC device, generally, the URLLC device may not know or care about transmissions from other UEs (for example, eMBB UEs) in PUSCH or PDSCH. Instead, a URLLC device can provide an indication that the URLLC device is prepared to transmit URLLC data on the resources indicated by the URLLC indicator, regardless of other transmissions that may occupy
Petition 870190087199, of 9/5/2019, p. 25/130
20/88 these resources and which can be programmed or in progress. In one aspect, when a base station transmits a URLLC indicator, no programming is used. In another aspect, a UE can be the URLLC device, but the base station can be used to transmit a URLLC indication.
[0057] From the perspective of an eMBB UE, the eMBB UE may have to deal with transmissions on the PUSCH from the URLLC device or transmissions to the URLLC device on the PDSCH. The URLLC device can simply provide an indication that the URLLC device is ready to transmit URLLC data on the indicated resources. The URLLC device can be a UE URLLC or a URLLC base station. Downlink interruptions due to URLLC data can be signaled by a downlink URLLC indicator. In this case, if the URLLC data occupies resources that are allocated to an eMBB UE (that is, when the URLLC data is incorporated into the eMBB data), the eMBB UE can decode a DL transmission based on that information. For example, the eMBB UE can determine that the URLLC data punctures its DL transmission and can perform decoding of the DLLC-punctured DL transmission based on this determination (for example, zero bits indicated as URLLC data). In the uplink, using the URLLC indicator, the eMBB UE can correspond to the rate of its transmission of eMBB data around the resources occupied by URLLC data sent from a base station.
[0058] In one example, a URLLC device can identify the availability of mini-partitions for
Petition 870190087199, of 9/5/2019, p. 26/130
21/88 URLLC data transmission in a set of one or more resource blocks. The URLLC device can generate a first transmission on a PUSCH, including URLLC data on at least one of the mini-partitions. The URLLC device can generate a second transmission comprising a URLLC indicator, to signal the presence of the URLLC data in at least one mini-partition. The URLLC device can send the first and second transmissions in the set of one or more resource blocks.
[0059] In one aspect, URLLC data can be transmitted in an uplink mini-partition which can be configured dynamically or semi-statically and which is identified for the base station by the URLLC indicator.
[0060] In one aspect, a URLCC device can send a URLLC data indicator. The URLLC data indicator can, in some examples, be sent regardless of whether URLLC data is present or not. For example, the URLLC indicator can indicate that the URLLC data is present and where the URLLC data is located in a transmission. The URLLC indicator can also indicate that no URLLC data is present in a particular transmission. Thus, a URLLC device can transmit a URLLC indicator to another device, such as an eMBB UE. The other device may be asked to monitor the URLLC indicator to determine if the URLLC data is present and then take the appropriate action when the URLLC data is present. For example, an EU eMBB can match the rate around the URLLC data or reset any received URLLC database based on the existence of URLLC data, as indicated
Petition 870190087199, of 9/5/2019, p. 27/130
22/88 by the URLCC indicator. In a case where the URLCC indicator indicates that there is no URLLC data, the other device may do nothing. For example, eMBB UE will not be required to match the rate of any data transmitted around URLCC data or to zero any data received. In other examples, URLLC indicators can only be sent when URLLC data is present.
[0061] In some respects, an indicator can be sent regardless of the presence of URLLC data. For example, a URLLC indicator can be sent periodically. In other respects, a URLLC indicator can only be sent when URLLC data is present.
[0062] In some respects, an indicator can be received, regardless of the presence of URLLC data. For example, a URLLC indicator can be received periodically (having been sent periodically by a URLLC device). In other respects, a URLLC indicator can be received only when URLLC data is present.
[0063] Fig. 2A is a diagram 200 illustrating an example of a DL subframe within a 5G / NR frame structure. FIG. 2B is a diagram 230 illustrating an example of channels within a DL subframe. FIG. 2C is a diagram 250 illustrating an example of a UL subframe within a 5G / NR frame structure. FIG. 2D is a 280 diagram illustrating an example of channels within a UL subframe. The 5G / NR frame structure can be FDD in which, for a particular set of subcarriers (the bandwidth of the carrier system), the subframes within
Petition 870190087199, of 9/5/2019, p. 28/130
23/88 of the set of subcarriers are dedicated to DL or UL, or can be TDD in which for a particular set of subcarriers (the bandwidth of the carrier system), the subframes within the set of subcarriers are dedicated to DL and to UL. In the examples provided by FIGs. 2A, 2C, the 5G / NR frame structure is assumed to be TDD, with subframe 4 a subframe of DL and subframe 7 a subframe of UL. Although subframe 4 is illustrated as providing only DL and subframe 7 is illustrated as providing only UL, any particular subframe can be divided into different subsets that provide UL and DL. Note that the description below also applies to a 5G / NR frame structure which is FDD.
[0064] Other non-wired communication technologies may have a different frame structure and / or different channels. A frame (10 ms) can be divided into 10 subframes of equal size (1 ms). Each subframe can include one or more time partitions. Each partition can include 7 or 14 symbols, depending on the partition configuration. For partition configuration 0, each partition can include 14 symbols, and for partition configuration 1, each partition can include 7 symbols. The number of partitions within a subframe is based on the partition configuration and numerology. For partition configuration 0, different numerologies from 0 to 5 allow 1, 2, 4, 8, 16 and 32 partitions, respectively, per subframe. For partition configuration 1, different numerologies from 0 to 2 allow 2, 4 and 8 partitions, respectively, per subframe. O
Petition 870190087199, of 9/5/2019, p. 29/130
24/88 subcarrier spacing and symbol length / duration are a function of numerology. The spacing of the subcarrier can be equal to 2 ^μ * 15 kKz, where μ is in numerology 0 to 5. The length / duration of the symbol is inversely related to the spacing of the subcarrier. FIGs. 2A, 2C provide an example of partition configuration 1 with 7 symbols per partition and numerology 0 with 2 partitions per subframe. The subcarrier spacing is 15 kHz and the symbol duration is approximately 66.7 ps.
[0065] A resource grid can be used to represent the framework structure. Each time partition includes a resource block (RB) (also referred to as physical RBs (PRBs)) that span 12 consecutive subcarriers. The resource grid is divided into several resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.
[0066] As illustrated in FIG. 2A, some of the REs carry reference signals (RS) (pilot) to the UE (indicated as R). The RS may include RS demodulation (DM-RS) and channel status information (CSI-RS) reference signals for channel estimation in the UE. The RS can also include beam measurement RS (BRS), beam refinement RS (BRRS) and phase tracking RS (PT-RS).
[0067] Fig. 2B illustrates an example of several channels within a DL subframe of a frame. The physical control format indicator (PCFICH) channel is within the 0 symbol of partition 0 and carries a control format indicator (CFI) that indicates whether the PDCCH occupies 1,
Petition 870190087199, of 9/5/2019, p. 30/130
25/88 or 3 symbols (FIG. 2B illustrates a PDCCH that occupies 3 symbols). The PDCCH carries the DCI within one or more control channel elements (CCEs), each CCE including nine RE groups (REGs), each REG, including four consecutive REs in an OFDM symbol. An UE can be configured with an enhanced UE-specific PDCCH (ePDCCH) that also carries the DCI. The ePDCCH can have 2, 4 or 8 pairs of RBs (FIG. 2B shows two pairs of RBs, each subset including a pair of RBs). The physical channel hybrid auto-repeat request (ARQ) indicator (HARQ) (PHICH) is also inside the 0 symbol of partition 0 and carries the HARQ (HI) indicator that indicates negative ACK / ACK (NACK) feedback. ) HARQ based on the shared physical uplink channel (PUSCH). The primary synchronization channel (PSCH) can be within the symbol 6 of partition 0 within subframes 0 and 5 of a frame. The PSCH carries a primary synchronization signal (PSS) that is used by a UE 104 to determine the subframe / symbol timing and an identity of the physical layer. The secondary synchronization channel (SSCH) can be within the 5 symbol of partition 0 within subframes 0 and 5 of a frame. The SSCH carries a secondary synchronization signal (SSS) that is used by a UE to determine a group number of physical layer cell identities and radio frame timing. Based on the physical layer identity and the group number of physical layer cell identities, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of DLPetition 870190087199, from 05/09/2019, pg. 31/130
26/88
RS mentioned above. The physical broadcast channel (PBCH), which carries a main information block (MIB), can be logically grouped with the PSCH and SSCH to form a synchronization signal (SS) / PBCH block. The MIB provides several RBs in the DL system's bandwidth, a PHICH configuration and a system frame number (SFN). The PDSCH carries user data, broadcast system information not transmitted through the PBCH, such as system information blocks (SIBs) and paging messages.
[0068] As illustrated in FIG. 2C, some of the REs carry demodulation reference signals (DM-RS) for channel estimation at the base station. The UE can additionally transmit audible reference signals (SRS) at the last symbol of a subframe. SRs can have a comb structure and a UE can transmit SRs on one of the combs. SRs can be used by a base station to estimate channel quality to allow frequency-dependent programming at UL. FIG. 2D illustrates an example of several channels within a UL subframe of a frame. A physical random access channel (PRACH) can be within one or more subframes within a frame based on the PRACH configuration. PRACH can include six consecutive pairs of RBs within a subframe. PRACH allows the UE to perform initial access to the system and obtain UL synchronization. A physical uplink control channel (PUCCH) can be located at the edges of the UL system bandwidth. PUCCH carries uplink control (UCI) information, such as scheduling requests, an

27/88 channel quality (CQI), a pre-coding matrix indicator (PMI), a classification indicator (RI) and ACK / NACK HARQ feedback. The PUSCH carries data and can additionally be used to carry a storage status report (buffer) (BSR), a power headroom report (PHR) and / or UCI.
[0069] FIG. 3 is a block diagram of a base station 310 in communication with a UE 350 on an access network. In DL, IP packets from EPC 160 can be provided to a 375 controller / processor. The 375 controller / processor implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control layer ( RRC) and layer 2 includes a packet data convergence protocol layer (PDCP), a radio link control layer (RLC) and a medium access control layer (MAC). The 375 controller / processor provides RRC layer functionality associated with broadcasting system information (for example, MIB, SIBs), RRC connection control (for example, RRC connection paging, RRC connection establishment, RRC connection modification and release of RRC connection), mobility of access technology and between radios (RAT) and measurement configuration for the UE measurement report; the functionality of the PDCP layer associated with header compression / decompression, security (encrypt, decrypt, integrity protection, integrity checking) and handover support functions; RLC layer functionality associated with the transfer of data units in upper layer packages (PDUs), error correction through ARQ,

28/88 concatenation, segmentation and re-assembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs and reorganization of RLC data PDUs; and the MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing MAC SDUs in transport blocks (TBs), demultiplexing MAC SDUs from TBs, programming information reporting, error correction through HARQ , priority treatment and prioritization of logical channel. In one aspect, an RRC configuration can be used by the UE to monitor the GC-DCI.
[0070] The transmit processor (TX) 316 and the receive processor (RX) 370 implement the layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical layer (PHY), can include error detection in transport channels, encoding / decoding of error correction (EEC) of transport channels, interleaving, rate matching, mapping in physical channels , modulation / demodulation of physical channels, and MIMO antenna processing. The TX 316 processor handles mapping to signal constellations based on various modulation schemes (for example, binary phase shift switch (BPSK), quadrature phase shift switch (QPSK), M phase shift switch (M -PSK), M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols can then be divided into parallel streams. Each flow can then be mapped to an OFDM subcarrier, multiplexed with a reference signal (for example, pilot) in the time domain and / or
Petition 870190087199, of 9/5/2019, p. 34/130
29/88 frequency, and then combined using a Fast Inverse Fourier Transform (IFFT) to produce a physical channel carrying a stream of OFDM symbols in the time domain. The OFDM stream is spatially precoded to produce various spatial streams. Channel estimates from a channel estimator 374 can be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate can be derived from a reference signal and / or feedback from the channel condition transmitted by the UE 350. Each spatial flow can then be provided to a different antenna 320 via a separate 318TX transmitter. Each 318TX transmitter can modulate an RF carrier with a corresponding spatial flow for transmission.
[0071] In UE 350, each 354RX receiver receives a signal through its respective antenna 352. Each 354RX receiver retrieves modulated information in an RF carrier and provides the information to the receiving processor (RX) 356. The TX 368 processor and the RX 356 processor implements layer 1 functionality associated with various signal processing functions. The RX 356 processor can perform spatial processing on the information to retrieve any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be combined by the RX 356 processor into a single OFDM symbol stream. The RX 356 processor then converts the OFDM symbol stream from the time domain to the frequency domain using a Fast Fourier Transform (FFT). The frequency domain signal
Petition 870190087199, of 9/5/2019, p. 35/130
30/88 comprises a separate stream of OFDM symbols for each sub-carrier of the OFDM signal. The symbols on each subcarrier and the reference signal are retrieved and demodulated by determining the most likely signal constellation points transmitted by base station 310. These flexible decisions can be based on channel estimates calculated by the channel estimator 358. Flexible decisions they are then decoded and deinterleaved to retrieve the data and control signals that were originally transmitted by base station 310 on the physical channel. The data and control signals are then provided to the 359 controller / processor, which implements layer 3 and layer 2 functionality.
[0072] The 359 controller / processor can be associated with a 360 memory that stores program codes and data. 360 memory can be referred to as a computer-readable medium. At UL, the 359 controller / processor provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression and control signal processing to retrieve IP packets from EPC 160. The 359 controller / processor is also responsible by detecting errors using an ACK and / or NACK protocol to support HARQ operations.
[0073] Similar to the functionality described in connection with DL transmission by base station 310, the 359 controller / processor provides RRC layer functionality associated with the acquisition of system information (eg, MIB, SIBs), RRC connections and reporting measurement; the PDCP layer functionality associated with the
Petition 870190087199, of 9/5/2019, p. 36/130
31/88 header compression / decompression and security (encryption, decryption, integrity protection, integrity checking); the functionality of the RLC layer associated with the transfer of top layer PDUs, error correction through ARQ, concatenation, segmentation and reassembly of RLC SDUs, re-segmentation of RLC data PDUs and reordering of RLC data PDUs; and the MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing MAC SDUs into TBs, demultiplexing MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling and prioritization of logical channel.
[0074] Channel estimates derived by a 358 channel estimator from a reference or feedback signal transmitted by base station 310 can be used by the TX 368 processor to select the appropriate coding and modulation schemes, and to facilitate the spatial processing. The spatial streams generated by the TX 368 processor can be provided to different antennas 352 via separate 354TX transmitters. Each 354TX transmitter can modulate an RF carrier with a corresponding spatial flow for transmission.
[0075] The UL transmission is processed at the base station 310 in a similar way to that described in connection with the receiver function in the UE 350. Each receiver 318RX receives a signal through its respective antenna 320. Each receiver 318RX retrieves information modulated in a RF carrier and provides the information for an RX 370 processor.
Petition 870190087199, of 9/5/2019, p. 37/130
32/88 [0076] The controller / processor 375 can be associated with a memory 376 that stores program codes and data. Memory 376 can be referred to as a computer-readable medium. At UL, the 375 controller / processor provides demultiplexing between transport and logical channels, packet reassembly, encryption, header decompression, control signal processing to retrieve IP packets from the UE 350. The 375 controller / processor IP Packets can be provided for EPC 160. The 375 controller / processor is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0077] FIG. 4 is a diagram 400 illustrating a base station 402 in communication with a UE 404. Referring to FIG. 4, when UE 404 is turned on, UE 404 searches for a nearby NR network. UE 404 discovers base station 402, which belongs to an NR network. Base station 402 transmits an SS block including PSS, SSS and PBCH (including MIB) periodically in different transmission directions 402a through 402h. UE 404 receives transmission 402e including PSS, SSS and PBCH. Based on the received SS block, the UE 404 synchronizes with the NR network and encapsulates in a cell associated with the base station 402.
[0078] In one aspect, a downlink indicator can be in the DCI. For example, the indicator can be part of the control information (for example, DCI). The uplink indicators can use a corresponding method or a corresponding method from any of the systems and methods described in this document.
Petition 870190087199, of 9/5/2019, p. 38/130
33/88 [0079] A downlink indicator can be a later indication, for example, appearing at the beginning of a next partition. The later indication can indicate whether the URLLC data is present on the partition or not before the indication.
[0080] In one aspect, a downlink indicator can be configured to be a broadband indication or a subband indication (for example, up to 2 subbands). Consequently, in some ways, the downlink indicator can spread over a wide part of a bandwidth. In other respects, the downlink indicator may be part of a subband.
[0081] Additionally, a downlink indicator can be configured to indicate one or more symbols, by configuring the monitoring periodicity. For example, a downlink indicator can be configured to indicate one or more symbols in a mini-partition or an indicator can be sent for each predetermined number of mini-partitions. The periodicity can be configured semi-statically or dynamically. Consequently, in one aspect, the periodicity can be configured semi-statically, for example, the periodicity can be reasonably fixed, but it can be configurable when updated or at some other period. In another aspect, the periodicity can be configured dynamically, for example, the periodicity can be configured at any time or almost any time by a network with which a UE or the base station is connected.
[0082] FIG. 5 is a diagram illustrating an example of a DL 500 frame structure.
Petition 870190087199, of 9/5/2019, p. 39/130
34/88 DL 500 frame includes eMBB 502 data and URLLC 506 data on a PDSCH 504. The DL 500 frame structure additionally includes PDCCH 510 and short bursts of uplink (ULSB) 512. URLLC 506 data and eMBB 502 data can be transmitted based on different transmission durations. For example, eMBB 502 data can follow a long format (for example, based on partitions). URLLC 506 data can follow a short format (for example, based on mini-partition).
[0083] In a first radio access network (RAN1), dynamic resource sharing between URLLC 506 data and eMBB 502 data can be supported. Consequently, the allocation of resources for URLLC 506 data and eMBB 502 data can be changed dynamically. For example, URLLC 506 data can appropriate or puncture a subset of resources occupied by eMBB data in progress 502. When URLLC 506 data appropriates resources occupied by eMBB data in progress 502, URLLC 506 data can replace overlapping resources occupied by eMBB data in progress 502, for example, the base station can transmit URLLC 506 data instead of transmitting eMBB 502 data on the indicated PDSCH 504 resources. When URLLC 506 data punctures resources occupied by eMBB data in progress 502, URLLC 506 data can be transmitted at the same time as resources occupied by eMBB data in progress 502, for example, the base station can transmit URLLC 506 data in PDSCH 504 resources allocated for eMBB 502 data.
[0084] In one aspect, for a transmission of
Petition 870190087199, of 9/5/2019, p. 40/130
35/88 downlink, a URLLC can puncture the eMBB. When a URLLC punctures an eMBB, the base station can only transmit URLLC data on the resources occupied by the URLLC. EMBB data can be matched according to missing resources. In other words, an eMBB UE can work around the resource elements that can be used for URLLC data. In such an example, a
base station can to be O transmitter and the UE can be the receptor.[0085] In one aspect, for a transmission of uplink, an eMBB HUH and an EU URLLC can to transmit simultaneously and transmit using < the same features.
Since the URLLC has a very high performance requirement, the URLLC data is likely to be transmitted with a much higher energy than the eMBB data on the occupied resource. Consequently, URLLC data can puncture eMBB data. In one aspect, when the eMBB UE and the URLLC UE are the same UE, the transmission of eMBB data can be skipped over the resources occupied by the URLLC data. For an EU eMBB receiving a downlink transmission, the resources used for a URLLC can be reset and / or ignored.
For an UE eMBB receiving an uplink transmission from the URLLC, the resources used for a URLLC cannot be used by the UE eMBB. Instead, the eMBB UE can match the fee to use other available resources that have been programmed for the eMBB UE.
[0086] RAN1 may use a URLLC indication (for example, URLLC indicator) to indicate when URLLC 50 6 data appropriates and / or punctures eMBB 502 data. An indication of appropriation or puncturing of

36/88
URLLC for an eMBB UE (104, 350, 404) related to an impacted eMBB resource can facilitate demodulation and decoding of the eMBB UE (104, 350, 404) of a current transmission and / or subsequent retransmissions.
[0087] FIGS. 6 through 11 illustrate project examples for a referral channel. The examples illustrate various locations within the frame structures of the referral channel. In some examples, an indication channel can be separated from the eMBB data and multiplexed by frequency division (FDM) or multiplexed by time division (TDM). (See FIGS. 6 through 8, 10 and 11.) In some examples, an indication channel can be incorporated into the eMBB data. (See FIGS. 9 and 11.) In other examples, an indication channel can be signaled in the concession or in the Radio Resource Control (RRC) configured by UE or by network configuration. (See Figures 6 to 8, 10 and 11).
[0088] FIG. 6 is a diagram illustrating an example of a DL frame structure. The DL 600 frame structure includes eMBB 602 data, a PDSCH 604, URLLC data 606, URLLC 608 indicators, a PDCCH 610, and the short uplink burst (ULSB) 612.
[0089] FIG. 6 illustrates an example of a separate indication channel design. In some examples of indication channel signaling, an indication can be signaled by mini-partition or by several mini-partitions. For example, one or more of the URLLC 608 indicators can be used.
[0090] In one aspect, the indication can be based on broadband, that is, the indication can indicate that the appropriation or the puncturing will be, for example,
Petition 870190087199, of 9/5/2019, p. 42/130
37/88 a whole band available. For example, referring to FIG. 2B, the one or more URLLC 608 indicators can indicate whether the URLLC data appropriates / punctures the entire bandwidth of the DL system. In one aspect, the indication may be based on a subband, that is, the indication may indicate that the appropriation or puncturing will use less than the entire available band, for example, a subband. For example, referring to FIG. 2B, the one or more URLLC 608 indicators can indicate whether the URLLC data appropriates / punctures a particular subset of subcarriers for the entire bandwidth of the DL system. In some respects, the indication may be based on RB or specific to the UE. Indications based on broadband or sub-band can be applied to all UEs using a broad band or that sub-band, for example, to appropriate or puncture with the URLLC.
[0091] A positive indication of a URLLC 606 data transmission, for example, during a scheduled eMBB 602 data transmission, may impact all RBs in a set of RBs in the PDSCH data, although not all RBs in the set of RBs are used by URLLC 606 data transmission. Consequently, the impact on all RBs can be a waste of resources and a degradation of performance. In some examples, the data in the RB set may be incomplete due to the PDSCH data. In another example, it may be possible to regenerate the data from eMBB 602 data, for example, punctured by PDSCH data, for example, due to data redundancy.
[0092] In one example, the indication can be
Petition 870190087199, of 9/5/2019, p. 43/130
38/88 based on RB. Thus, the indication can be made on a basis by RB or by group of RBs, for example, every 4 RBs.
For example, referring to FIGs. 2A, 2B, one or more URLLC 208 indicators can provide an indication for x RBs, where x> 1.
[0093] In a specific EU example, an indication can be sent on a per EU basis. Consequently, such an indication can be sent directly to a particular UE and can be applied only to that UE. In one aspect, a referral may have a different referral periodicity. Consequently, the indication periodicity can be configurable. For example, the periodicity of the URLLC indicator can be configured semi-statically or dynamically. For a specific EU indication, the indicator can be by mini-partition or by group of mini-partitions. Some examples may use a single-bit indication per UE or several bits per UE for the indication. In the case of a single bit indication, the bit can be set when at least one RB of the eMBB UE is occupied. A multi-bit indication can provide a better frequency resolution to indicate which RB or groups of RBs in an eMBB UE are occupied.
[0094] An illustrative URLLC indicator can use a long burst UL structure at partition level in terms of DMRS design or other design aspects. For example, a PUCCH channel structure can be used to transmit the URLLC indicator.
[0095] The shared DMRS can be used for all indications throughout all miniPetition 870190087199, from 05/09/2019, pg. 44/130
39/88 partitions. The indication bits can be coded separately or coded together. Joint encoding may perform better, but it may delay decoding. In addition, the joint encoding may need to store the PDSCH. Separate encoding can support instant decoding of indication bits, but the bits can be divided into groups of indication bits. A URLLC indicator can be transmitted using TDM / FDM or CDM.
[0096] FIG. 7 is a diagram illustrating an example of a DL frame structure. The DL frame structure having a separate 700 indication channel design includes eMBB data 602, a PDSCH 604, URLLC data 606, a URLLC indicator 608, a PDCCH 610 and a short burst of uplink (ULSB) 612. The example illustrates a separate indication channel design 700. The separate indication channel design 700 can utilize a short burst UL structure at mini-partition level. The separate indication channel design 700 may have the short burst with or without DMRS (for example, to obtain DMRS sharing between different mini-partitions). In addition, the separate indication channel design 700 can support instant decoding of indication bits. As illustrated in FIG. 7, the URLLC 608 indicator can be part of the PDSCH 604.
[0097] FIG. 8 is a diagram illustrating an example of a DL frame structure. The DL 800 frame structure includes eMBB 602 data, a PDSCH 604, URLLC data 606, a URLLC indicator 608 (608A, 608B), a PDCCH 610, short burst of uplink (ULSB) 612. The indicator

40/88
URLLC 608A is a common group PDCCH on PDSCH 604. The URLLC 608A indicator is a common group PDCCH on PDCCH 610. The example can use a common group PDCCH 610 structure (channel type PCFICH), i.e., DCI. The indicator can be carried in a DCI message common to a group. For example, a common group 610 PDCCH can be used by a common group of devices. In one example, a BS can send a set of UEs the DCI message including one or more URLLC indicators to each mini-partition. In another example, a common PDCCH 610 can be used by a common group of devices at each mini-partition. In one example, a BS can send a set of UEs the DCI message including one or more URLLC indicators every few mini-partitions. How often DCI messages are sent is configurable. In one example, the RS can be shared with the DCI per partition. In another example, the URLLC indicator can use the DCI message once per partition. When the URLLC indicator uses the DCI message once per partition, that indicator can be transmitted at the beginning of the next partition after the transmission of the URLLC data.
[0098] FIG. 9 is a diagram illustrating an example of a DL frame structure. The DL 600 frame structure includes eMBB 602 data, a PDSCH 604, URLLC data 606, a URLLC 608 indicator, a PDCCH 610 and short uplink burst (ULSB) 612.
[0099] An example can use an embedded indication channel design (URLLC 608 indicator). The design of the embedded referral channel can be incorporated into the eMBB 602 data region. In addition, the
Petition 870190087199, of 9/5/2019, p. 46/130
41/88 the indication channel may have a comb-based structure, as illustrated in FIG. 9.
[00100] In one example, all four tones can be used for an indication channel. Additionally, in an example, when a URL6 606 data transmission is not present, the URLLC 608 indicator may not be sent, for example, to save overhead. In addition, in an example, when a URLLC 606 data transmission is present, the comb-based referral channel can also be transformed into DMRS for the corresponding EU URLLC 104, 350, 404. In one aspect, the URLLC 606 data can correspond at the rate around the referral channel (DMRS).
[00101] For an indication monitoring duration (one or more mini-partitions), eMBB UE can perform blind location detection for URLLC DMRS to see if URLLC 606 data is present. Blind detection can be similar to an ACK on the LUS PUSCH, but on a comb-based transmission. The grouping of RBs (for example, grouping of sub-bands) of an indication channel can be used to increase the processing gain and to ensure the reliability of blind decoding. In addition, spatial separation, scrambling, pre-coding or other non-wired communication processes can be used to reduce a false alarm rate in blind decoding.
[00102] One aspect may include a specific cell collection of RBs that can be used by a UE that transmits a URLLC. The UE that transmits a URLLC can be signaled by a broadcast message (or in
Petition 870190087199, of 9/5/2019, p. 47/130
42/88 a concession). The UE transmitting a URLLC can then use predefined mini-partitions within the RBs to transmit a URLLC indicator. The URLLC indicator can point to the mini-partitions being used. In addition, the mini-partitions being used can be coded together or separately, depending on the requirements for the granularity of information in the mini-partitions versus the overhead for processing the mini-partitions.
[00103] The following aspects can also be valid for the indicator project, regardless of whether the indicator is transmitted in a separate resource from the eMBB data or incorporated in the URLLC.
[00104] In one aspect, an indication design can include an indication that can be at the beginning or at the end of a mini-partition. In another example, the indication can be at the beginning or at the end of a partition. In yet another example, the indication can be at the beginning or at the end of a set of several mini-partitions.
[00105] In one aspect, an indication design can be by mini-partition (partitions). A mini-partition design can allow pipeline demodulation and / or decoding processing.
[00106] In one aspect, an indication design may include the indication, may be dynamically or semi-statically signaled, whether the indication is separated or incorporated, whether the sub-band or EU indication, may be signaled, and / or granularity of indication.
[00107] In one aspect, an indication can be broadcast and can be based on sub-band, such as a
Petition 870190087199, of 9/5/2019, p. 48/130
43/88 indication of appropriation applying to a corresponding subband.
[00108] In one aspect, an indication can be transmitted by unicast to an UE 104, 350, 404. The indication can be by UE per mini-partition (per ownership unit). Additionally, multiplexing across UEs can be TDM / FDM or CDM. Additionally, the coding of the indicator channel can be coded independently or in groups.
[00109] FIG. 10 is a diagram illustrating an example of a UL frame structure. The DL 1000 frame structure includes eMBB data 1002, a PDSCH 1004, URLLC data 1006, a URLLC indicator 1008, a PDCCH 1010 and the short uplink burst (ULSB) 1012. The ideas discussed in relation to FIGS. 6 through 9 for DL transmissions from a base station 102, 310, 402 to an UE 104, 350, 404 can be applied to UL transmissions from an UE 104, 350, 404 to a base station 102, 310, 402.
[00110] For programmed URLLC data 1006, base station 102, 310, 402 may need to send a URLLC indicator 608 to eMBB UE in advance so that eMBB PDSCH 1004 can match the rate around URLLC data 1006.
[00111] Some examples may use the same indication structure as described in relation to FIGs. 6 to 9 to indicate a URLLC 1006 data transmission on an UL partition. For example, as discussed above, FIG. 6 is a diagram illustrating an example of a DL frame structure. The DL 600 frame structure of FIG. 6 includes eMBB 602 data, a PDSCH
Petition 870190087199, of 9/5/2019, p. 49/130
44/88
604, URLLC data 606, URLLC indicators 608, a PDCCH 610 and the short burst of uplink (ULSB) 612. FIG. 6 illustrates an example of a separate indication channel design. In some examples of indication channel signaling, an indication can be signaled by the mini-partition or by several mini-partitions. For example, one or more of the URLLC 608 indicators can be used. FIG. 7 is a diagram illustrating an example of a DL frame structure. The DL frame structure of the 700 indication channel design includes eMBB data 602, a PDSCH 604, URLLC data 606, a URLLC indicator 608, a PDCCH 610 and an ULSB 612. The example illustrates a separate 700 indication channel design FIG. 8 is a diagram illustrating an example of a DL frame structure. The DL 800 frame structure includes eMBB data 602, a PDSCH 604, URLLC data 606, a URLLC indicator 608, a PDCCH 610, ULSB 612. FIG. 9 is a diagram illustrating an example of a DL frame structure. The DL 600 frame structure includes eMBB 602 data, a PDSCH 604, URLLC data 606, a URLLC indicator 608, a PDCCH 610, ULSB 612.
[00112] In some examples, the URLLC 1008 indicator can be transmitted on a previous partition with a separate channel. Some examples may reuse the UL short and / or long burst channel structure in a main DL part. Some examples can reuse DCI in the main DL part or in the PDCCH region. Some examples can transmit on a current partition in the PDCCH region. Some examples can reuse DCI. The indication channel for data transmission of DL and UL URLLC 1006 can be TDM / FDM / CDM.
Petition 870190087199, of 9/5/2019, p. 50/130
45/88 [00113] As illustrated in FIG. 10, the indicator
URLLC 1008 can be transmitted embedded 1114, in a previous partition 1014 or in a current partition 1016.
[00114] FIG. 11 is a diagram illustrating an example of a UL frame structure. The DL 1100 frame structure includes eMBB data 1102, a PUSCH 1104, URLLC data 11011, a URLLC indicator 1108, a PDCCH 1110 and the short burst of uplink (ULSB) 1112.
[00115] FIG. 11 illustrates examples of URLLC 1108 indications for transmission without programming. The programming request (SR) URLLC or URLLC data 1106 can punch the eMBB PUSCH 1104. In the example of FIG. 11, the URLLC UE 104, 350, 404 may need to transmit an indication to the base station 102, 310, 402 (e.g., eNB, gB). EMBB UE 104, 350, 404 may not be aware of the presence of the URLLC transmission. Consequently, an indication can be transmitted on the separate channel in a long burst or in a short burst. In one example, an indication can be a short transmission. Additionally, in some examples, the URLLC indicator 1108 from different URLLC UEs 104, 350, 404 can be TDM / FDM / CDM.
[00116] In some examples, the URLLC 1108 indicator can be incorporated in the long burst with a comb-based structure. As illustrated in FIG. 11, the URLLC indicator 1108 can be transmitted embedded 1114, in a ULSB 1112 in a short burst and / or in PUSCH 1104 in a long burst.
[00117] As described in this document, in one aspect, an URLCC device can send a URLLC data indicator. The URLLC data indicator may, in some cases,
Petition 870190087199, of 9/5/2019, p. 51/130
46/88 examples, be sent regardless of whether URLLC data is present or not. For example, the URLLC indicator can indicate that the URLLC data is present and where the URLLC data is located in a transmission. The URLLC indicator can also indicate that no URLLC data is present in a specific transmission. Thus, a URLLC device can transmit a URLLC indicator to another device, such as an eMBB UE. The other device may be requested to monitor the URLLC indicator to determine whether URLCC data is present and to take appropriate measures when URLLC data is present. For example, an eMBB UE can match the rate around the URLLC data or zero any URLLC database received when there is URLLC data as can be indicated by the URLCC indicator. In one case when the URLCC indicator indicates that there is no URLLC data, the other device may do nothing. For example, eMBB UE will not be asked to match the rate of any data transmitted around URLCC data or to zero any data received. In other examples, URLLC indicators can only be sent when URLLC data is present.
[00118] FIG. 12 is a flow chart 1200 of a non-wired communication method. The method can be carried out by a base station (for example, the base station 102, 310, 402, the apparatus 1802, 1802 '). In 1202, the base station generates a set of resource blocks including at least one of the eMBB data or URLLC data in a PDSCH. The URLLC data can be one of the data embedded in the eMBB data or one that is not embedded in the eMBB data.
Petition 870190087199, of 9/5/2019, p. 52/130
47/88
For example, referring to FIGS. 6 through 9, the base station (e.g., base station 102, 310, 402, apparatus 2202, 2202 ') can generate a set of resource blocks, such as the resource blocks illustrated in FIGS. 2A, 2C. Resource blocks can include at least one of the eMBB 602 data or the URLLC 606 data on a PDSCH 604. An example of a PDSCH 604 structure is illustrated in FIG. 2B. As illustrated in FIGS. 6 through 9, URLLC 606 data may be incorporated into eMBB 602 data. URLLC 606 data may not be incorporated or separated from eMBB 602 data.
For example, URLLC 606 data may not exist. Generate a set of resource blocks including at least one of the eMBB 602 data or the URLLC data in a PDSCH can include obtaining the MBB data, the URLLC data or the MBB data and the URLLC data and mapping the data for the resource block set. Generating a set of resource blocks including at least one of the eMBB 602 data or URLLC data in a PDSCH may include embedding the URLLC data in the eMBB 602 data or not incorporating the URLLC data into the eMBB 602 data.
[00119] In 1204, the base station generates a URLLC indicator indicating whether the set of resource blocks includes at least part of the URLLC data. For example, as illustrated in FIGS. 6 through 9, the base station (for example, base station 102, 310, 402, the handset
2202, 2202 ') generates a URLL 608 indicator indicating whether the resource block set includes URLLC 606 data. In one aspect, the URLLC 608 indicator can be a downlink indicator in the DCI. For example, FIG. 8, illustrates a common group PDCCH indicator 608B, that is, an indicator
Petition 870190087199, of 9/5/2019, p. 53/130
48/88 downlink in the DCI. Generating a URLLC 608 indicator, indicating whether the resource block set includes the URLLC 606 data can include determining when the resource block set should include the URLLC 606 data and creating a 608 indicator based on that determination.
[00120] In one aspect, an indication may include a later indication. For example, the indication in FIG. 8 can be a later indication, that is, an indication at the beginning of the next one or more partitions. For example, the later indication may appear at the beginning of the next partition. See, for example, FIG. 8, in which the common group PDCCH indicator 608B is on a partition after the corresponding URLLC appropriation or puncturing resources occupied by an ongoing eMBB communication have occurred. The indication can indicate whether URLLC 606 data is present or not. In one aspect, an indication can be configured to be a broadband indication, for example, the appropriate data space (which may or may not be used entirely for data) uses all or a large part of a band or bands in one partition. For example, ownership can span all of a carrier's subcarriers. FIG. 2B illustrates an example of a downlink system bandwidth where ownership can occur. In one aspect, an indication can be configured to be a subband indication, for example, the appropriate data space - which may or may not be used entirely for data uses a small or minor part of a band or bands in a partition compared to broadband. For example, ownership can extend through one or
Petition 870190087199, of 9/5/2019, p. 54/130
49/88 more subsets of the carrier's subcarriers. FIG. 2B illustrates an illustrative downlink system bandwidth where ownership can occur. The sub-band indication can be used to indicate the use of two sub-bands. The indication can be configured to indicate one or more symbols, configuring the monitoring periodicity.
[00121] The generation of a URLLC 608 indicator indicating that the URLLC 606 data is within the resource block part with the eMBB 602 data may include determining that the URLLC 606 data is within the resource block part with the eMBB 602 data and / or create the URLLC 608 indicator based on the determination.
[00122] In 1206, the base station sends, to at least one UE, the URLLC indicator and the set of resource blocks including at least one among the eMBB data or the URLLC data. The URLLC indicator can be sent separately from the URLLC data within the DCI of a PDCCH. For example, referring to FIGS. 6 through 9, the base station (e.g. base station 102, 310, 402, device 2202, 2202 ') can send to at least one UE (e.g. UE 104, 350, 404, device 2002 , 2002 ') the URLLC 608 indicator and the set of resource blocks including at least one of the eMBB 602 data or the URLLC 606 data. With reference to FIGS. 6 through 8, the URLLC 608 indicator can be sent separately from the URLLC 606 data within the DCI of a PDCCH 610. For example, see the common group PDCCH indicator 608B of FIG. 8. An illustrative PDCCH is illustrated in FIG. 2B. In some respects, a 608 indicator can be sent regardless of the
Petition 870190087199, of 9/5/2019, p. 55/130
50/88 presence of URLLC 606 data. For example, a URLLC 608 indicator may be sent periodically. In other respects, a URLL 608 indicator can only be sent when URLLC 606 data is present. Sending the URLLC 608 indicator and the set of resource blocks including eMBB 602 data and URLLC 606 data to at least one UE (for example, UE 104, 350, 404, appliance 2002, 2002 ') may include providing the URLLC 608 indicator and the set of resource blocks for a transmission device and / or cause the URLLC 608 indicator and the set of resource blocks to be transmitted. Send at least one UE (for example, UE 104, 350, 404, device 2002, 2002 ') the URLLC 608 indicator and the set of resource blocks including at least one of the eMBB 602 data or the URLLC data 606 may include transferring information to a transmitter and having the transmitter transmit the information. The information can include the URLLC 608 indicator and the set of resource blocks including at least one of the eMBB 602 data or the URLLC 606 data. The information can also indicate how to send the URLLC 608 indicator and the set of resource blocks, for example For example, the URLLC 608 indicator can be sent embedded within the URLLC 606 data or it can be sent separately from the URLLC 60 6 data in the DCI of a PDCCH (indicator 608B). The URLLC 608 indicator can be within a separate indicator channel.
[00123] In 1208, the base station sets a periodicity to send the URLLC indicator. For example, the base station (for example, the base station 102, 310, 402, the handset 2202, 2202 ') can configure a periodicity
Petition 870190087199, of 9/5/2019, p. 56/130
51/88 to send the URLLC 608 indicator. Thus, the timing for sending the URLLC indicator can be configurable. The timing for the periodicity can be determined by the base station (for example, the base station 102, 310, 402, the handset 2202, 2202 ') and the base station (for example, the base station 102, 310, 402, the handset 2202, 2202 ') can transmit that timing to a UE (e.g., UE 104, 350, 404, apparatus 2002, 2002'), for example, as RRC signaling. The base station (for example, the base station 102, 310, 402, the device 2202, 2202 ') can dynamically configure a periodicity to send the URLLC indicator 608. Consequently, the indicator can be sent with a variable periodicity. In another aspect, the base station (e.g., base station 102, 310, 402, apparatus 2202, 2202 ') can semi-statically configure a periodicity to send the URLLC indicator. Consequently, the indicator can be sent with a frequency that does not change or does not change frequently, for example, such as when communications between a particular UE and a particular base station begins. Setting a periodicity to send the URLLC 608 indicator can include selecting a time period and / or applying the time period for sending step 1206.
[00124] In one aspect, the URLLC indicator can be sent separately from the URLLC data. The URLLC indicator can be within the DCI of a common group PDCCH. For example, the URLLC 608 indicator can be sent separately from the URLLC 606 data. (See FIGS. 7 and 8). The URLLC indicator 608 can be within the DCI of a common group PDCCH 610. (See 608B, FIG. 8).
Petition 870190087199, of 9/5/2019, p. 57/130
52/88 [00125] In one aspect, the base station's resource block set includes eMBB data. The indicator indicates whether URLLC data is embedded in eMBB data. For example, referring to FIGS. 6 through 9, in one aspect, the set of resource blocks (for example, see RB, FIGS. 2A, 2C) from the base station (for example, the base station 102, 310, 402, the apparatus 2202, 2202 ') includes eMBB 602 data. Additionally, indicator 608 indicates whether URLLC 606 data is incorporated into eMBB 602 data.
[00126] In one aspect, the base station resource block set includes the URLLC data in the PDSCH. Additionally, the URLLC indicator indicates that the URLLC data is present in the set of resource blocks. For example, referring to FIGS. 6 through 9, the base station resource block set (for example, base station 102, 310, 402, handset 2202, 2202 ') includes URLLC data 606 in PDSCH 604. Additionally, the URLLC indicator
608 indicates what o the URLLC data 606 are gifts at the set of resource blocks. Examples of blocks in reference can be found in FIGs. 2A and 2C.[ 00127] In one respect, the URLLC indicator is
sent embedded in URLLC data. For example, referring to FIGS. 6 through 9, in one aspect, the URLLC 608 indicator can be sent embedded within the URLLC 606 data.
[00128] In one aspect, the set of resource blocks is sent on a partition before a partition on which the URLLC indicator is sent. The URLLC indicator can be a later indication indicating whether the resource block set includes at least part of the URLLC data.
Petition 870190087199, of 9/5/2019, p. 58/130
53/88
For example, the set of resource blocks is sent on the partition before the partition on which the URLLC 608 indicator is sent. The URLLC 608 indicator can be a later indication indicating whether the resource block set includes the URLLC 606 data. For example, the URLLC 606 data before is illustrated as being before the URLLC 608B indicator in FIG. 8.
[00129] FIG. 2B illustrates examples of bandwidth of the downlink system. In one respect, the URLLC indicator is based on broadband and indicates that the URLLC data spans all of a carrier's subcarriers. In one aspect, the URLLC indicator is based on sub-bands and indicates that the URLLC data extends through one or more subsets of the carrier's subcarriers. For example, the URLLC 608 indicator can be based on broadband and can indicate that URLLC 606 data extends across all of a carrier's subcarriers. In one aspect, the URLLC 608 indicator is based on sub-bands and indicates that the URLLC 606 data extends through one or more subsets of the carrier's subcarriers.
[00130] In one aspect, the set of resource blocks can be transmitted in a partition before a partition in which the URLLC indicator is received. The URLLC indicator can include a later indication. The later indication can indicate whether the set of resource blocks received in the partition before the partition in which the indicator
URLLC is passed includes the data URLLC.[00131] One aspect can transmit an configuration for transmit the URLLC indicator. THE
configuration can specify a periodicity at which the
Petition 870190087199, of 9/5/2019, p. 59/130
54/88 URLLC indicator is transmitted.
[00132] FIG. 13 is a flowchart 1300 of a non-wired communication method. The method can be performed by a UE (e.g., UE 104, 350, 404, the apparatus 2002, 2002 '). In 1302, the UE receives a set of resource blocks from a base station including eMBB data. For example, referring to FIGS. 6 through 9, the UE (e.g. UE 104, 350, 404, apparatus 2002, 2002 ') can receive a set of resource blocks from a base station (e.g., base station 102, 310, 402, apparatus 2202, 2202 ') including eMBB 602 data. Receiving the set of resource blocks including a PDSCH from the base station may include tune with a base station, receive data from the base station, determine the resource blocks to be from the base station and / or determine the PDSCH of the received resource block.
[00133] In 1304, the UE receives a URLLC indicator from the base station. The URLLC indicator is received within the DCI of a PDCCH. The URLLC indicator indicates whether the resource block set includes URLLC data. URLLC data can be incorporated into eMBB data. For example, the UE (for example, the UE 104, 350, 404, the 2002, 2002 'handset) can receive a URLLC 608 indicator from the base station (for example, the base station 102, 310, 402, the handset 2202, 2202 '). For example, referring to FIG. 9, the URLLC 608 indicator can also be received embedded within the URLLC 606 data. To refer specifically to FIG. 8, the URLLC indicator 608 can be within the DCI of a PDCCH 610. For example, see common group PDCCH indicator 608B of FIG. 8. A format
Petition 870190087199, of 9/5/2019, p. 60/130
55/88 illustrative for the PDCCH can be found in FIG. 2B. The URLLC 608 indicator can be the received URLLC 608 indicator, it can be sent as part of the bits that make up the DCI. The URLLC 608 indicator indicates whether the resource block set includes URLLC 606 data. Referring to FIGS. 6 through 9, in one example, URLLC 606 data can be incorporated into eMBB 602 data. URLLC 606 data does not always appropriate or puncture resources occupied by eMBB communication. In some respects, an indicator can be received, regardless of the presence of URLLC 606 data. For example, a URLLC indicator can be received periodically. In other respects, a URLLC indicator can be received only when URLLC 606 data is present. Receiving a URLLC 608 indicator from the base station may include tuning to a base station, receiving data from the base station and / or determining the indicator from the base station.
[00134] In 1306, the UE determines, based on the URLLC indicator, whether the set of resource blocks includes the URLLC data incorporated within the eMBB data. For example, referring to FIGS. 6 through 9, the UE (for example, UE 104, 350, 404, the apparatus 2002, 2002 ') determines, based on the URLLC 608 indicator, whether the set of resource blocks includes URLLC 606 data incorporated in the eMBB 602 data Determine, based on the URLLC indicator, whether the resource block set includes the URLLC 606 data can include the processing of received signals, including the URLLC indicator, to determine the URLLC indicator and process the URLLC indicator to determine whether the set of blocks resource includes URLLC 606 data
Petition 870190087199, of 9/5/2019, p. 61/130
56/88 [00135] In 1308, a decision is made based on the determination in 1306. When the URLLC indicator determines that the set of resource blocks includes URLLC data, block 1310 can be executed. When the URLLC indicator determines that the resource block set does not include URLLC data, the 1312 data block can be executed.
[00136] In 1310, the UE processes the resource block set based on a result of determining whether the resource block set includes URLLC data (for example, when eMBB data is present in the resource block set, take into account when processing eMBB data that URLLC data is embedded in eMBB data). For example, the UE (for example, the UE 104, 350, 404, the appliance 2002, 2002 ') can process the resource block set based on a result of determining whether the resource block set includes the URLLC 606 data using one or more of the processors 356, 368, 359 illustrated in FIG. 3. The received resource block set including at least one of the eMBB 602 data or URLLC 606 data. Process the received resource block set including at least one of the eMBB 602 data or URL6 606 data, it may include reading a memory location by storing the URLLC indicator to determine the status of the indicator (or otherwise determining the status of the indicator) and processing resource blocks based on the status of the indicator. In one aspect, processing may include matching rates around the embedded URLLC data or discarding the URLLC data based on the URLLC indicator. In one respect, the UE can
Petition 870190087199, of 9/5/2019, p. 62/130

[00137] In 1312, the UE processes the resource block set based on a result of determining whether the resource block set includes URLLC data (for example, when no URLLC data is present). For example, the UE (for example, the UE 104, 350, 404, the appliance 2002, 2002 ') can process (for example, on a 356, 368, 359 processor), process the set of resource blocks based on a result of determining whether the resource block set includes the URLLC 606 data. Processing the received set of resource blocks including at least one of the eMBB 602 data or the URLLC 606 data may include reading a location in memory storing the URLLC indicator for determine the state of the indicator (or otherwise, determine the state of the indicator) and process resource blocks based on the state of the indicator. In one aspect, the UE can send an ACK / NACK as part of 1312.
[00138] In 1314, a UE receives a configuration to receive the URLLC indicator at a particular periodicity. The configuration can be received dynamically or semi-statically. For example, a UE (for example, UE 104, 350, 404, apparatus 2002, 2002 ') may receive a configuration to send the URLLC indicator at a particular periodicity. In one aspect, the UE (for example, the UE 104, 350, 404, the apparatus 2002, 2002 ') can dynamically receive a configuration to send the URLLC 608 indicator at a particular periodicity. Consequently, the indicator can be sent with an alterable frequency. In one respect, the UE (for example,
Petition 870190087199, of 9/5/2019, p. 63/130
58/88 the UE 104, 350, 404, ο device 2002, 2002 ') can semi-statically receive a configuration to send the URLLC 608 indicator at a particular periodicity. Consequently, the indicator can be sent with a frequency that does not change or does not change frequently, for example, such as when communication between a particular UE and a particular base station starts. In one aspect, the configuration can specify a periodicity at which the URLLC indicator is transmitted. In one aspect, after the appropriation has taken place, an UE (for example, UE 104, 350, 404, apparatus 2002, 2002 ') can send an acknowledgment (ACK) when some appropriate data has been properly decoded in the UE, for example example, due to replacement, redundancy or both; or a negative acknowledgment (NACK) when some appropriate data is decoded incorrectly. For example, the ACK or NACK can be sent back to the base station. An aspect can transmit one of an ACK or a NACK based on whether the set of resource blocks is decoded correctly when processing the set of resource blocks. Block 1314 can occur to prepare for a subsequent execution of the flowchart (or as an initial step in the flowchart) in some examples, [00139] In one aspect, the URLLC indicator can be received separately from the URLLC data. The URLLC indicator can be within the DCI of a common group PDCCH. For example, referring to FIGS. 7 through 8, the URLLC 608 indicator can be received separately from the URLLC 606 data. The URLLC 608 indicator can be within the DCI of a common group 610 PDCCH.

Indicator 608 indicates whether the URLLC 606 data is embedded within the eMBB 602 data.
[00141] In one aspect, the resource block set from the base station includes the URLLC data in the PDSCH. Additionally, the URLLC indicator indicates that the URLLC data is present in the set of resource blocks. For example, referring to FIGS. 6 through 9, the set of resource blocks from the base station (for example, base station 102, 310, 402, device 2202, 2202 ') includes URLLC data 606 in PDSCH 604. Additionally, the URLLC indicator 608 indicates that URLLC 606 data is present in the resource block set.
[00142] In one aspect, the URLLC indicator is received embedded in the URLLC data. For example, referring to FIGS. 6 through 9, in one aspect, the URLLC 608 indicator can be received embedded within the URLLC 606 data.
[00143] In one aspect, the set of resource blocks is received on a partition before a partition on which the URLLC indicator is received. The URLLC indicator

For example, the set of resource blocks is received on a partition before the partition on which the URLLC 608 indicator is received. The URLLC 608 indicator can be a later indication indicating whether the resource block set includes URLLC 606 data. For example, see URLLC 606 data, which is before the URLLC 608B indicator in FIG. 8.

[00149] In 1406, a UE sends the URLLC indicator and the set of resource blocks, including URLLC data, to a base station. For example, UE 104, 350, 404 sends URLLC 1108 indicator and set of resource blocks including URLLC 1106 data to a base station 102, 310, 402 (See FIG. 11). In some ways, an indicator can be sent regardless of the presence of URLLC data. For example, a URLLC indicator can be sent periodically. In other respects, a URLLC indicator can only be sent when URLLC data is present.
