ALLOCATION OF UPLINK ACK RESOURCES IN NEW RADIO CROSS REFERENCE TO RELATED APPLICATIONS [0001] This Patent Application claims priority for Provisional Application No. 62 / 470,784, entitled UPLINK ACK RESOURCE ALLOCATION IN NEW RADIO, filed March 13, 2017, and U.S. Patent Application No. 15 / 917,487, entitled UPLINK ACK RESOURCE ALLOCATION IN NEW RADIO and filed on March 9, 2018, which are expressly incorporated herein by reference in full.
BACKGROUND [0002] Aspects of the present invention refer, in general, to wireless communication networks and, more particularly, to the allocation of ACK / NACK resources in
communications without thread. [0003] Networks in Communication without wire are widely employed for provide several types of content of communication, such as voice, video, Dice of package,
messages, broadcasts and more. These systems can be multiple access systems capable of supporting communication with multiple users by sharing available system resources (for example, time, frequency and power). Examples of such multiple access systems include code division multiple access systems (CDMA), time division multiple access systems (TDMA), frequency division multiple access systems (FDMA), division multiple access systems orthogonal frequency (OFDMA) and single carrier frequency division multiple access systems (SCFDMA).
Petition 870190089475, of 10/09/2019, p. 8/91
2/59 [0004] These multiple access technologies have been adopted in several telecommunication standards to provide a common protocol that allows different wireless devices to communicate at the municipal, national, regional and even global levels. For example, a fifth generation (5G) wireless communication technology (which can be called Novo Rádio (NR)) is designed to expand and support various usage scenarios and applications in relation to generations of current mobile networks. In one respect, 5G communication technology can include: enhanced mobile broadband that handles user-centered use cases for access to multimedia content, services and data; ultra-reliable low-latency communications (URLLC) with certain latency and reliability specifications; and massive machine-type communications, which can allow a very large number of connected devices and the transmission of a relatively low volume of non-delay-sensitive information. As the demand for mobile broadband access continues to increase, however, further improvements in NR communication technology may be desired.
[0005] For example, in Novo Rádio (NR), several downlink (DL) / uplink (UL) sub-bands can be configured to allocate positive confirmation (ACK) / negative confirmation (NACK) resources (for example, ACK / NACK resources). However, the mapping between the DL and UL sub-bands is not limited to one-to-one mapping and there may also be cross-partition programming. Thus, improvements to efficiently allocate ACK resources in wireless communications may be desired.

DETAILED DESCRIPTION [0031] Several aspects are now described with
Petition 870190089475, of 10/09/2019, p. 15/91
9/59 reference to drawings. In the following description, for the sake of explanation, several specific details are presented in order to provide a complete understanding of one or more aspects. It may be evident, however, that such aspects can be practiced without these specific details. Additionally, the term component, as used here, can be one of the parts that make up a system, can be hardware, firmware and / or software stored in a computer-readable medium, and can be divided into other components.
[0032] The present invention provides aspects that allow a UE to identify uplink control information resources (UCI) within a set of specific UE resources based on an indication received from a gNB, combined with implicit mapping and / or explicit, and / or based on a payload size of an UCI to be transmitted. In such cases, the set of UE-specific resources can be a subset of a grouping of gNB resources, and can be grouped into multiple different sets of physical resources (for example, multiple sets of different UE-specific resources).
[0033] For example, in an implementation of identifying one or more UCI resources within a set of specific UE resources, a UE may receive a radio resource control (RRC) configuration that is transmitted by a gNB and indicating the set of specific features of the UE. In addition, the UE can receive a physical downlink control channel (PDCCH) that includes a positive confirmation feature configuration
Petition 870190089475, of 10/09/2019, p. 16/91
10/59 (ACK) / corresponding negative acknowledgment (NACK). The configuration of ACK / NACK resources (for example, configuration information) can tell the UE which UCI resource (s) (for example, ACK / NACK resource (s)) of the specific UE resource set must be used by the UE to transmit ACK / NACKs on physical uplink control channels (PUCCHs) to the gNB. For example, in some non-limiting cases, the ACK / NACK resource configuration includes a positive confirmation resource (ARI) indicator, and the UE determines which resource (s) from the specific UE resource set to use with based on an ARI value. Alternatively or additionally, for example, in some other non-limiting cases, the UE determines which resource (s) from the specific UE resource pool to use based on an implicit mapping method. In some cases, the UE may determine which resource (s) from a control channel element (CCE) location by configuring the ACK / NACK resource configuration. Alternatively or additionally, for example, in still other non-limiting cases, the UE determines which resource (s) from the set of specific UE resources to use based on an explicit mapping with some DCI bits, in addition to ARI bits . For example, some invalid DCI bits can be used to indicate one of the resources in the resource set. Alternatively or additionally, for example, in still other non-limiting cases, the UE determines which resource (s) from the specific UE resource pool to use based on at least one of the downlink subband mapping information ( DL) / uplink (UL), partition programming information
Petition 870190089475, of 10/09/2019, p. 17/91
11/59 cross-over or an ACK / NACK resource configuration format. When determining the ACK / NACK or UCI resource (s) to use from the UE-specific resource set, the UE can transmit ACK / NACKs to the gNB using the ACK / NACK resource (s) determined (s).
[0034] Additionally, for example, in another implementation of identifying UCI resources within a set of specific UE resources, the UE can determine a payload size for a UCI to be transmitted in a PUCCH. The UE can then identify a set of UE-specific UCI resources selected from the multiple UE-specific resource sets to transmit the UCI in the PUCCH based, at least in part, on the size of the UCI payload. For example, the UE can determine the UE-specific UCI resource set selected from multiple UE-specific resource sets based on a mapping of different payload size ranges to the respective of the multiple specific resource sets of the UE. HUH.
[0035] The present solutions can address one or more problems with pre-Novo Rádio (NR) / 5G LTE technologies, which employed implicit mapping techniques for configuring ACK / NACK in a PDCCH. However, such techniques may not be entirely suitable for NR / 5G operations. For example, an eNB LTE can be an aggregated carrier cell with a primary cell and one or more secondary cells. LTE eNBs can use implicit mapping to allocate (for example, assign, identify, etc.) ACK / NACK resources to a primary cell and
Petition 870190089475, of 10/09/2019, p. 18/91
12/59 explicit selection with ACK / NACK resource indicator (ARI) to allocate ACK / NACK resources to a secondary cell. In addition, for example, an ACK / NACK resource can be a time / frequency resource that can identify a frequency, offset, code division multiplexing (CDM), etc. associated with the specific ACK feature. LTE techniques do not consider the existence of multiple DL / UL sub-bands in NR / 5G, however, leading to collisions between carriers.
[0036] In NR, multiple DL / UL sub-bands can be configured and DL sub-bands and UL sub-bands can have one-to-one mapping or a many-to-one mapping (more than one sub -DL band mapped to a UL sub-band). If multiple DL sub-bands are mapped to a UL sub-band, the techniques used in LTE are not suitable and, as discussed here, ACK resources can be allocated / allocated in order to minimize and / or avoid collisions of resources. In other words, the ACK resource is not generally assigned to multiple PUCCHs from different UEs.
[0037] The various aspects described in the present invention provide multiple techniques for mapping ACK / NACK resources within a set of UE specific resources for use by the UE based on configuration information indicated by the PDCCH, using a combination of implicit rules and explicit, and / or based on a payload size of an UCI to be transmitted. Defining mapping schemes for use by the UE and gNB to identify one or more resources within the set of specific UE resources that can be used to
Petition 870190089475, of 10/09/2019, p. 19/91
13/59 transmitting an ACK / NACK during a PUCCH, the present invention reduces the likelihood of collisions between ACK / NACK transmissions from multiple UEs. The various aspects thus provide a technical improvement in the area of telecommunications and, specifically, NR, reducing the likelihood of an ACK / NACK collision and the resulting unsuccessful ACK or NACK reception.
[0038] Additional features of the present aspects are described in greater detail below with respect to Figures 1-9.
[0039] It should be noted that the techniques described in this document can be used for various wireless communication networks, such as CDMA, TDMA, FDMA, OFDMA, SCFDMA, and other systems. The terms system and network are generally used interchangeably. A CDMA system can implement radio technology, such as CDMA2000, Universal Terrestrial Radio Access (UTRA) etc. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. IS-2000 Versions 0 and A are commonly referred to as CDMA2000 IX, IX etc. IS-856 (TIA-856) is commonly referred to as CDMA2000 IxEV-DO, High Rate Packet Data (HRPD) etc. UTRA includes Broadband CDMA (WCDMA) and other CDMA variants. A TDMA system can implement radio technology, such as the Global System for Mobile Communications (GSM). An OFDMA system can implement radio technology, such as Ultra-Mobile Broadband (UMB), Evolved UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM ™ etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). Long Term Evolution (LTE) and Advanced LTE (LTE-A) 3GPP
Petition 870190089475, of 10/09/2019, p. 20/91
14/59 are versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from the organization called 3rd Generation Partnership Project (3GPP). CDMA2000 and UMB are described in documents from an organization called 3rd Generation Partnership Project 2 (3GPP2). The techniques described in this document can be used for the radio systems and technologies mentioned above, as well as other radio systems and technologies, including cellular communications (for example, LTE) over a shared radio frequency band. The description below, however, describes an LTE / LTE-A system for purposes of example, and LTE terminology is used in most of the description below, although the techniques are applicable in addition to LTE / LTE-A applications (for example , 5G networks or other next generation communication systems).
[0040] The following description provides examples, and does not limit the scope, applicability or examples presented in the claims. Changes can be made to the function and arrangement of elements discussed without departing from the scope of the invention. Various examples may omit, replace, or add various procedures or components, as appropriate. For example, the methods described can be performed in a different order than described, and several steps can be added, omitted or combined. In addition, the features described with respect to some examples can be combined into other examples.
[0041] With reference to Figure 1, according to various aspects of the present invention, a network of
Petition 870190089475, of 10/09/2019, p. 21/91
15/59 exemplary wireless communication 100 includes at least one user equipment (UE) 110 with a modem 140 having a communications component 150 that manages the execution of a radio resource control (RRC) / physical channel receiving component downlink control (PDCCH) 152, an ACK / NACK 154 resource determination component, and / or an ACK / NACK 156 transmission component. The exemplary wireless communication network 100 may further include a gNB or a station base 105 with a modem 180 having a communications component 190 that manages the execution of a PDCCH transmitting component 192 and / or an ACK / NACK receiving component 194 for receiving ACK / NACKs from UE 110.
[0042] According to the present invention, for example, gNB 105 can transmit one or more PDCCHs to the UE 110. PDCCHs can include configuration of ACK / NACK resources (for example, configuration information) which can indicate to the UE 110 the ACK / NACK resources to be used by the UE 110 to transmit ACK / NACKs on the physical uplink control channel (PUCCH) to gNB 105. For each PDCCH received from gNB 105, the UE 110 can determine the ACK / NACK resources NACK based on at least a payload and / or a location of the PDCCH. The payload and / or location of the PDCCH can contain at least one of DL / UL subband mapping information, cross partition programming information, ACK formats, and / or ARIs. When determining ACK / NACK resources, the UE 110 can transmit ACK / NACKs to the gNB 105 using the determined ACK / NACK resources.
[0043] Wireless communication network 100 can
Petition 870190089475, of 10/09/2019, p. 22/91
16/59 include one or more base stations 105, one or more UEs 110 and a core network 115. The core network 115 can provide user authentication, access authorization, tracking, internet protocol (IP) connectivity and other functions access, routing or mobility. Base stations 105 can interface with core network 115 via backhaul links 120 (e.g., SI etc.). Base stations 105 can perform radio configuration and programming to communicate with UEs 110, or they can operate under the control of a base station controller (not shown). In several examples, base stations 105 can communicate, directly or indirectly (for example, via core network 115), with each other via backhaul links 125 (for example, XI etc.), which can be links cable or wireless communication.
[0044] Base stations 105 can communicate wirelessly with UEs 110 through one or more base station antennas. Each of the base stations 105 can provide communication coverage for a respective geographical coverage area 130. In some examples, the base stations 105 can be referred to as a base transceiver station, a radio base station, a access, a radio transceiver, a Node B, eNode B (eNB), gNB, a domestic Node B, a domestic eNode B, or some other suitable terminology. Geographic coverage area 130 for a base station 105 can be divided into sectors or cells that make up only a portion of the coverage area (not shown). Wireless communication network 100 can include base stations 105 of different types (for example,
Petition 870190089475, of 10/09/2019, p. 23/91
17/59 example, macrocell base stations or small cell base stations, described below). In addition, the plurality of base stations 105 can operate according to different technologies from a plurality of communication technologies (for example, 5G (New Radio or NR), fourth generation (4G) / LTE, 3G, Wi-Fi, Bluetooth etc.) and, thus, there may be overlapping of geographical coverage areas 130 for different communication technologies.
[0045] In some instances, wireless communication network 100 is one or any combination of communication technologies, including NR or 5G technology, Long Term Evolution (LTE) or Advanced LTE (LTE-A) technology or MuLTEfire, a Wi-Fi technology, a Bluetooth technology, or any other short- or long-range wireless communication technology. In LTE / LTEA / MuLTEfire networks, the term evolved Node B (gNB) can be used in general to describe base stations 105, while the term UE can be used in general to describe UEs 110. The communication network wireless 100 can be a heterogeneous technology network, in which different types of gNBs provide coverage for various geographic regions. For example, each gNB or base station 105 can provide communication coverage for a macrocell, a small cell and / or other types of cell. The term cell is a 3GPP term that can be used to describe a base station, a carrier or component carrier associated with a base station, or a coverage area (for example, sector etc.) of a carrier or base station. basis, depending on the context.
Petition 870190089475, of 10/09/2019, p. 24/91
18/59 [0046] A macrocell can generally cover a relatively wide geographical area (for example, several kilometers in radius) and can allow unrestricted access by UEs 110 with service subscriptions with the network provider.
[0047] A small cell can include a base station with less relative transmission power, compared to a macrocell, which can operate in the same or in different frequency bands (for example, licensed, shared etc.) than the macrocells. Small cells can include pico-cells, femto-cells and microcells according to several examples. A picocell can cover a smaller geographical area and can allow unrestricted access by the UEs 110 with service subscriptions with the network provider. A femto-cell can also cover a small geographical area (for example, domestic) and can provide restricted access and / or unrestricted access by the UEs 110 having an association with the femtocell (for example, in the case of restricted access, the UEs 110 in a Closed Subscriber Group (CSG) from base station 105, which may include UEs 110 for home users, and the like). A gNB for a macrocell can be referred to as a macro-gNB. A small cell gNB can be referred to as a small cell gNB, a pico-gNB, a femto-gNB or a domestic gNB. A gNB can support one or more (for example, two, three, four and the like) cells (for example, component carriers).
[0048] The communication networks that can accommodate some of the various examples disclosed may be networks based on packets that operate according to a stack of
Petition 870190089475, of 10/09/2019, p. 25/91
19/59 layered protocols and data in the user plane can be based on IP. A user plan protocol stack (for example, packet data convergence protocol (PDCP), radio link control (RLC), MAC, etc.) can perform segmentation and reassembly of packets for communication through logical channels. For example, a MAC layer can perform priority management and multiplexing of logical channels into transport channels. The MAC layer can also use hybrid automatic retry request (HARQ) to provide retransmission at the MAC layer to improve link efficiency. In the control plane, the RRC protocol layer can provide for establishing, configuring and maintaining an RRC connection between an UE 110 and base stations 105. The RRC protocol layer can also be used to support radio bearers over the core network 115 for user plan data. In the physical layer (PHY), transport channels can be mapped to physical channels.
[0049] UEs 110 can be dispersed over wireless communication network 100, and each UE 110 can be stationary or mobile. A UE 110 can also include or be
referred powder r those versed in technique like an station mobile, a station of subscriber, one unit mobile, a unity in subscriber, a wireless unit, an unity remote, one device mobile one device without wire one
wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a telephone device, a user agent, a mobile client, a customer or some other suitable terminology. a

UE 110 can be a cell phone, a smartphone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a portable device, a tablet, a laptop, a cordless phone, a smart watch, a local wireless circuit station (WLL), an entertainment device, a vehicle component, customer site equipment (CPE) or any device capable of communicating on the wireless communication network 100. Additionally, a UE 110 can be an Internet of Things (loT) and / or machine-machine (M2M) device, for example, a low power, low data rate device (compared to a cordless phone, for example), that can , in some ways, communicating infrequently with the wireless communication network 100 or other UEs 110. An UE 110 may be able to communicate with various types of base stations 105 and network equipment, including macro-gNBs, small cell gNBs a, macro-gNBs, small cell gNBs, relay base stations and the like.
[0050] An UE 110 can be configured to establish one or more wireless communication links 135 with one or more base stations 105. The wireless communication links 135 shown on wireless communication network 100 can carry uplink transmissions ( UL) from a UE 110 to a base station 105, or downlink transmissions (DL), from a base station 105 to a UE 110. Downlink transmissions can also be called direct link transmissions, while uplink transmissions they can also be called reverse link broadcasts. Each wireless communication link 135 can include one or more
Petition 870190089475, of 10/09/2019, p. 27/91
21/59 carriers, where each carrier can be a signal composed of multiple subcarriers (for example, waveform signals of different frequencies) modulated according to the various radio technologies described above. Each modulated signal can be sent on a different subcarrier and can carry control information (for example, reference signals, control channels, etc.), overhead information, user data, etc. In one aspect, wireless communication links 135 can transmit bidirectional communications using frequency division duplexing (FDD) operation (for example, using paired spectrum resources) or time division duplexing (TDD) (for example, using unpaired spectrum resources). Frame structures can be defined for FDD (for example, frame type 1) and TDD (for example, frame structure type 2). In addition, in some respects, wireless communication links 135 may represent one or more broadcast channels.
[0051] In some aspects of the wireless communication network 100, base stations 105 or UEs 110 may include multiple antennas to employ antenna diversity schemes to improve the reliability and quality of communication between base stations 105 and UEs 110. In addition or alternatively, base stations 105 or UEs 110 may employ multiple input and multiple output (MIMO) techniques that can take advantage of multipath environments to transmit multiple spatial layers carrying the same or different encoded data.

A UE 110 can be configured with multiple downlink CCs and one or more uplink CCs for carrier aggregation. Carrier aggregation can be used with both component carriers FDD and TDD.

[0054] Additionally, one or more of the base stations 105 and / or UEs 110 can operate according to an NR or 5G technology referred to as millimeter wave technology (mmW or mmwave). For example, mmW technology includes transmissions at mmW frequencies and / or nearby mmW frequencies. Extremely high frequency (EHF) is part of the radio frequency (RF) in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 mm and 10 mm.

[0055] With reference to Figures 2A and 2B, an exemplary ACK resource allocation 200 for
Petition 870190089475, of 10/09/2019, p. 30/91
24/59 PUCCH formats include implicit mapping, and an allocation of resources from the exemplary ACK LTE 201 to PUCCH 1b format includes explicit mapping with ARI. GNB 105 can be an aggregated carrier cell with a primary cell (PCell) and one or more secondary cells (Scells).
[0056] In such an aggregated carrier configuration, the gNB 105 can use PUCCH 210 format with implicit mapping to allocate (for example, assign, identify, etc.) ACK / NACK resources for a PCell and an explicit selection with resource indicator ACK / NACK (ARI) 260 to allocate ACK / NACK resources to a SCell. For example, an ACK / NACK resource can be a time / frequency resource that can identify a frequency, offset, code division multiplexing (CDM), etc. associated with the specific ACK feature. An ACK / NACK resource can be referred to as an ACK resource in the present invention, however, the ACK resource can be used to transmit an ACK or a NACK.
[0057] gNB 105 can transmit PDCCHs 212, 214, 216 and / or 218 that can be associated with PCell; and can transmit PDCCHs 262, 264, 266 and / or 268 that can be associated with SCell. For PCell, gNB 105 can assign ACK resources using implicit mapping which can include assigning ACK resources based on the indication of an initial downlink control channel (CCE) element resource from a pool of resources, for example, resource pool 220. For example, PDCCHs 212, 214, 216 and / or 218, CCE resources 222, 224, 226 and / or 228 can be assigned,
Petition 870190089475, of 10/09/2019, p. 31/91
25/59 respectively, which can be indicated based on your initial CCE (for example, a CCE number). The use of the initial CCE to identify ACK resources minimizes the overhead in the UE 110 notification about which ACK resources the UE 110 should use to transmit an ACK to a specific PDCCH. Implicit mapping can also result in not having to explicitly indicate which ACK feature to use.
[0058] For SCell, for cross-carrier programming, gNB 105 can use implicit mapping, as described above in the context of PCell.
[0059] However, for non-cross carrier programming, gNB 105 can use PUCCH 260 format with explicit ARI-based mapping for assigning ACK resources to SCell to avoid collisions (eg collisions due to assigning it) ACK feature for two PUCCHs). For example, for SCell, gNB 105 can assign ACK resources 272, 276, 274 and / or 278 (from resource pool 270) to PDCCHs 262, 266, 264 and / or 268, respectively. In one aspect, gNB 105 can also include ARI 282 to be transmitted on PDCCH 262. For example, ARI 282 can contain two bits that can include four possibilities (for example, 00, 01, 10, 11) to identify resources of ACK. An example value of 00 for ARI 282 can identify ACK 272 resources, an example value of 10 for ARI 282 can identify ACK 276 resources, and so on. The use of ARI 282 for explicit selection of ACK resources can minimize collisions in noncross carrier programming configurations.

26/59 [0060] Figures 3A and 3B illustrate exemplary subband dependent mappings 310 and 350 according to aspects of the present invention.
[0061] For example, in NR, multiple DL / UL sub-bands can be configured and DL sub-bands and UL sub-bands can have one-to-one mapping or many-to-one mapping ( more than one DL subband mapped to a UL subband). In an implementation, if DL / UL sub-bands are mapped one-to-one, the implicit mapping, described above with reference to Figure 2, can be used. However, if more than one DL subband is mapped to a UL subband, ACK resources should be allocated / allocated in order to minimize / avoid resource collisions. In other words, the ACK resource is not generally assigned to multiple PUCCHs from different UEs.
[0062] In one aspect, more than one subband of DL can be mapped to one subband of UL. In this scenario, subband dependent mapping can be performed in several ways. For example, all CCEs in the DL sub-band and all ACK resources in the UL sub-bands can be numbered together and sub-band deviations can be sent through radio resource control (RRC) configuration or system information blocks (SIBs). The implicit mapping, described above with reference to Figure 2, can be used. In yet another such implementation, the CCEs in the DL sub-bands and the ACK resources in the UL sub-bands are numbered independently. In this scenario where CCEs and ACK resources are numbered independently, a subband of DL can be mapped
Petition 870190089475, of 10/09/2019, p. 33/91
27/59 for a UL subband, and each DL subband has an ACK resource bypass. ACK resources can be selected based on the initial CCE and subband deviation. The subband deviation can be broadcast to the UEs through system information blocks (SIBs). In another aspect, resource groupings can be diffused through SIBs or through RRC settings, and ARIs in the PDCCH can indicate the specific ACK resources to use.
[0063] As illustrated in Figure 3A, four DL subbands (312, 314, 316 and 318) are shown and each DL subband can transmit multiple PDCCHs. For example, in subband 312, two PDCCHs, PDCCH1 322 and PDCCH2 323 can be transmitted. On the UE 110 side, two sub-bands of UL 330 and 340 are shown and each UL sub-band can have multiple ACK resources. For example, the UL 330 subband may have ACK resources 332, 334, 336 and / or 338. The lines from a DL subband to UL subbands show the mapping of multiple PDCCHs (or PDCCH channels) ) per DL subband for multiple ACK resources in the UL subband. For example, the PDCCH1 322 and PDCCH2 323 of the DL 312 subband can be mapped to the ACK resources 332 and 334 of the UL 330 subband, and the PDCCH3 324 and PDCCH4 325 of the DL subband 314 can be mapped to the ACK 342 and 344 resources of the UL 330 subband.
[0064] Additionally, as illustrated in Figure 3B, four DL sub-bands (352, 354, 356 and 358) are shown and each DL sub-band can transmit multiple PDCCHs. For example, in subband 352, two PDCCHs, PDCCH5
Petition 870190089475, of 10/09/2019, p. 34/91
28/59
362 and PDCCH6, 364 can be transmitted. On the UE 110 side, two sub-bands of UL 370 and 380 are shown and each sub-band of UL can have multiple ACK resources. For example, the UL 370 subband may have ACK 372, 374, 376 and / or 378 resources. The lines from a DL subband to UL subbands show the mapping of multiple PDCCHs (or PDCCH channels) per DL subband for multiple ACK resources in the UL subband. However, the mapping is based on ARI within the PDCCH payload and the mapping can be randomized. For example, PDCCH5 362 and PDCCH6 364 of the DL 352 subband can be mapped to the ACK 372 and 378 resources of the UL 370 subband, and PDCCH7 366 and PDCCH8 368 of the DL subband 356 can be mapped to the ACK 374 and 376 resources of the UL 330 subband.
[0065] In an implementation, for example, an ARI value received on a PDCCH can be used in conjunction with implicit mapping for resource allocation within a specific UE resource set for PUCCH transmissions. In one example, each set of UE-specific resources can include a number of PUCCH resources. For example, the number of PUCCH resources in the resource set can be 8 to 32. In some cases, the PUCCH resources can be physical resources in one or more UL sub-bands mapped from more than one sub- DL band and thus the present aspects operate to avoid collisions. For example, UE 110 can receive configuration information from the gNB that identifies the specific feature set of the UE (for example, 8 to 32 resources). The UE 110 can then
Petition 870190089475, of 10/09/2019, p. 35/91
29/59 receive the ARI at the PDCCH. In an example where the ARI has a P-bit value (for example, P can be equal to 3 or 4), UE 110 can implicitly map a P-bit ARI value to a subset of specific UE resources (for example, a subset of the 4 to 8 PUCCH resources in one or more UL sub-bands) that should be used to transmit UCI, such as an ACK / NACK. In other words, the UE 110 can map from different values of the ARI bits to different subsets of the UE's specific resource set, and in addition, the UE 110 can use implicit mapping to select specific resources within the subset identified by the ARI. In this way, the UE-specific resource set is semi-statically configured and ARI bits are used by the UE 110 to perform dynamic resource selection from a subset of the UE's specific resources.
[0066] In one aspect, if the number of ARI bits is P_ARI, and the UE 110 requires more than 2 ^A b_ARI resources for UCI transmission, then the UE 110 can use the implicit mapping mentioned above, and can additionally receive an explicit indication of specific additional UE resources to use. In another example, a 3-bit ARI with up to 8 PUCCH resources per resource set can be implemented. And implicit mapping can be used when the number of resources in the resource pool is greater than 8.
[0067] Figures 4A and 4B illustrate exemplary cross-partition programming configurations.
[0068] Figure 4A illustrates an aggregate DL centric partition programming configuration 400 with
Petition 870190089475, of 10/09/2019, p. 36/91
30/59
PDCCH scheduling PDSCH transmissions, PDCCHs 411 and 413 scheduling PDSCH transmission 410 and 420. In such an aggregated DL configuration, for example, two consecutive DL centric partitions 410 and 420, different mapping functions with different offsets can be used to same partition programming and cross partition programming. In one aspect, ACK / NACKs for PDCCHs 422 and 424 are transmitted in a short burst of uplink from partition 420 (for example, cross-partition) and ACK / NACK for PDCCH 426 is transmitted in short uplink burst from the same partition, partition 420. As illustrated in Figure 4A, although PDCCH channels corresponding to 424 and 426 are transmitted on the same resource on different partitions, they are mapped to a different ACK resource on the same ULSB. The mapping can be done with different partition dependent deviation combined with implicit mapping of initial PDCCH CCEs, or with explicit ARI selection in the PDCCH.
[0069] Figure 4B illustrates an aggregated UL centric partition scheduling configuration 450 with PDCCH scheduling PDSCH transmissions, PDCCHs 461 and 463 scheduling PDSCH transmissions 460 and 470. In such a configuration, for example, with two DL centric partitions consecutive aggregates 460 and 470 and two consecutive aggregated UL partitions 480 and 490, multiple PDCCHs, for example, PDCCHs 464 and 474, can be mapped to the same ACK resource if ACK / NACKs are to be transmitted over a long duration different partitions, for example, over long 480 and 490 partitions. In an implementation, a partition dependent deviation can be
Petition 870190089475, of 10/09/2019, p. 37/91
31/59 added, which is subtracted from a CCE deviation. For example, ACK resource = initial CCE - deviation from CCE. The partition-dependent deviation can be communicated to the UE 110 through RRC or SIB configuration. In another implementation, ARI can be used to explicitly indicate ACK capabilities.
[0070] Figure 5 illustrates an example of an ACK 500 format, which can be varied, according to aspects of the present invention.
[0071] In one aspect, Figure 5 illustrates a 4-bit ACK 550 for PDSCHs 510, 520, 530 and / or 540. In the example, the ACK bits for multiple PDSCHs in different partitions are transmitted together on the same PUCCH channel , referred to as the multibit ACK transmission based on the HARQ group. In one aspect, a PDSCH can have multiple blocks of code (CBs) and an ACK bit can correspond to a group of CB (CBG) with one or more CBs per CBG. Multiple ACK bits can be transmitted to different CBGs in a PDSCH. Therefore, the payload size of the ACK channel may be different. Multiple ACK formats can be defined for different payload size ranges. The ACK capabilities for different payload formats / sizes may be different. For example, ACK resources with a payload of 1 or 2 bits can have a resource pool (for example, first resource pool), ACK resources with a 2-10 bit payload can have a resource pool different (for example, second resource pool), and ACK resources with 10+ bits may have another resource pool (for example, third resource pool).
Petition 870190089475, of 10/09/2019, p. 38/91
32/59 [0072] In one aspect, different ACK formats can have different groupings of resources. For example, gNB 110 can indicate different ACK formats, payload sizes and / or CBG sizes through downlink control information (DCI) or the UE 110 can use certain implicit rules to determine ACK formats, sizes payload and / or CBG sizes. UE 110, when determining ACK formats, can use the implicit mapping or use the ARI indication, as described above, to select the resource index within the resource pool. In an additional aspect, for HARQ group-based multibit ACKs, implicit mapping can be used based on the first or last PDCCH in the group. The HARQ range group can be signaled by defining Kl values in the PDCCH or configuring a time interval in the PDCCH. In an example in Figure 5, a Kl value set on the PDCCH to 4, 3, 2, 1 can result in 4 ACK bits corresponding to the 4 PDSCH channels to be transmitted together. In an additional implementation, the ACK payload size can be dynamically configured. As a result, the number of RBs can be different and / or the number of RBs can be derived from the ACK payload size.
[0073] In one aspect, for example, the UE 110 can select a set of UCI resources from one or more (up to K = 4) sets of UCI resources configured based on the UCI payload size, for example, not including a CRC. A set of UCI resources for UCI payload size can be in the range of {Ν ^,. . .Ni ₊ i] bits (i = 0,..., Kl). In some cases, the value
Petition 870190089475, of 10/09/2019, p. 39/91
33/59 of N can be set to certain values of i. For example, for í equal to 0 or 1, N ₀ = l and Ni = 2. In this way, any remaining values of í can correspond to specific UE resource sets. For example, continuing with the example above, for i = 2, ..., Kl, Ni can be configured specifically for UE 110. In one example, the value of N is in the range of {4, 256} with a granularity 4-bit. Nt can represent a maximum UCI payload size, which can be implicitly or explicitly derived. In some examples, N ^ can be configured semi-statically in the RRC configuration. In addition, in some respects, for a given UCI payload range, a set of PUCCH resources may contain resources for short PUCCH and resources for long PUCCH.
[0074] With reference to Figure 6, for example, a method 600 of wireless communication including determining ACK / NACK capabilities on UE 110 in accordance with the aspects described above is disclosed.
[0075] For example, in 605, method 600 includes receiving, from a gNB, a radio resource control (RRC) configuration indicating a set of specific UE resources, which is a subset of a grouping of gNB resources . For example, in one aspect, the UE 110 and / or the modem 140 can execute the communications component 150 and / or the RRC / PDCCH 152 receiving component to receive the RRC configuration from gNB 105. The RRC configuration can contain information that directs or otherwise links the UE to a subset of the gNB resource pool. The subset of
Petition 870190089475, of 10/09/2019, p. 40/91
34/59 gNB resource pool assigned to the UE can be specific to the UE, thus avoiding collisions, and the RRC setting can tell the UE which resources resources available in the gNB resource pool the UE should use to transmit ACK / NACKs or other UCI information. In this way, the UE's specific feature set can be semi-statically updated by the RRC configuration.
[0076] For example, in 610, method 600 includes receiving, from a gNB, a physical downlink control channel (PDCCH) including a corresponding ACK / NACK resource configuration. In some cases, the received PDCCH may be one of one or more PDCCHs, each including a corresponding ACK / NACK resource configuration. For example, in one aspect, UE 110 and / or modem 140 may execute communications component 150 and / or RRC / PDCCH 152 receiving component to receive one or more PDCCHs from gNB 105, each including a configuration corresponding ACK / NACK resources. As described above, each PDCCH can include an ACK / NACK resource configuration that indicates to UEs, for example, UE 110, the ACK / NACK resources from the set of specific UE resources indicated in the RRC configuration to be used by the UE 110 to transmit ACK / NACKs or another UCI on the PUCCH. As a reference, in one example, the ACK / NACK resource configuration includes an ARI having a set of bits, in which different values of the sets of bits can be used to indicate different subsets of the specific UE resources to be used.
[0077] In addition, in 620, method 600 includes
Petition 870190089475, of 10/09/2019, p. 41/91
35/59 determine, in the UE, one or more ACK / NACK resources from the UE-specific resource set for an upcoming PUCCH based, at least in part, on the ACK / NACK resource configuration. For example, in one aspect, UE 110 and / or modem 140 may perform communications component 150 and / or the ACK / NACK resource determination component 154 to determine one or more ACK / NACK resources associated with the PDCCH. The UE 110 and / or the ACK / NACK resource determination component 154 can determine the ACK / NACK resources based, at least in part, on the ACK / NACK configuration.
[0078] For example, in one aspect, when the ACK / NACK configuration includes the ARI and the UE specific feature set is semi-statically configured, the UE 110 uses a value of the ARI bits to perform dynamic resource selection of an subset of the EU's specific resources. For example, UE 110 can map different values of ARI bits to different subsets of the UE specific feature set. In addition, as described above, UE 110 can use implicit mapping to select specific resources within the subset identified by the ARI.
[0079] In one aspect, as described above, the configuration of ACK / NACK which can implicitly and / or explicitly indicate which resources from the set of specific resources of the UE should be used by the UE 110 in the transmission of ACK / NACKs.
[0080] In one aspect, the set of UE-specific resources can include N resources, and the ARI can be b_ARI -bits, where different values of the b_ARI bits
Petition 870190089475, of 10/09/2019, p. 42/91
36/59 indicate different subsets of the N resources. If the UE 110 requires more than 2 ^A b_ARI resources for UCI transmission, then the UE 110 can use the implicit mapping mentioned above, and can additionally receive an explicit indication of specific additional UE resources to use. For example, if N = 16, b_ARI bits = 3, each ARI value will indicate a subset of resources from the 16 resources. Each subset of resources can contain 2 resources. An implicit mapping method is used to further select one of the two resources in the resource subset. In another example, a 3-bit ARI with up to 8 PUCCH resources per resource set can be implemented. In this example, an ARI value will select one of up to 8 resources. No implicit mapping is additionally necessary.
[0081] In some respects, the implicit mapping method that determines one or more ACK / NACK resources from the subset of specific UE resources is further based on a location of a control channel element (CCE) carrying the configuration of ACK / NACK resources. An example is described above with reference to Figure 2A.
[0082] In some respects, the determination of the ACK / NACK resources to be used can be based at least on the DL / UL subband mapping function described with reference to Figures 3A and 3B, cross partition programming information described with reference to Figures 4A and 4B, ACK formats described above with reference to Figure 5, and / or ARIs.
[0083] Optionally, in 630, method 600 can
Petition 870190089475, of 10/09/2019, p. 43/91
37/59 optionally include the transmission, from the UE, of an ACK / NACK to a shared physical downlink channel (PDSCH) on at least one of the one or more ACK / NACK resources determined based, at least in part, configuration of ACK / NACK resources. In some cases, such a PDSCH can be one of one or more PDSCHs associated with a respective PDCCH of one or more PDCCHs that can be received by the UE 110. For example, in one aspect, the UE 110 and / or the modem 140 can perform the communications component 150 and / or transmission component of ACK / NACK 156 to transmit ACK / NACK to a PDSCH using at least one of the determined ACK / NACK resources.
[0084] ACK / NACK resource configuration information transmitted from gNB 105 and / or received on UE 110 may include any combination of one or more of the downlink sub-band (DL) / uplink mapping information, cross-partition programming, ACK formats, or ACK / NACK resource indicators (ARIs) that are included in the corresponding PDCCH resource configuration.
[0085] In some cases, the subband mapping information is based on a mapping of a plurality of downlink subbands to one or more uplink subbands. In one respect, the subband mapping information is based on a global numbering of downlink control channel (CCE) element resources and uplink ACK resources. In one respect, the subband mapping information is based on an implicit mapping of downlink control channel (CCE) element resources and sub dependent deviations
Petition 870190089475, of 10/09/2019, p. 44/91
38/59 band.
[0086] In one respect, cross partition programming information includes different mapping functions for cross partition programming and same partition programming settings. In one respect, cross-partition scheduling information is determined by mapping PDCCHs to the same resource when the ACK / NACK resource configuration indicates that
an ACK / NACK must be transmitted in a Long term in different partitions. [0087] In a aspect, the ARI it's an index in multilevel resource that includes a or more sub-indexes band and one or more identifiers appeal what
identify at least one resource corresponding to each subband identified by one or more subband indices.
[0088] In this way, the ARI values included in the PDCCH can be interpreted differently in UE 110. For example, in an implementation, ARI can be a multilevel resource index that can be a two-level resource index that includes a combination of subband index and resources within a subband. In another example, ARI can be a three-tier resource index that can include a subband index, payload size (for example, resource pool size) and / or a resource index within the resource pool . In an additional example, ARI can be a four-level index if the short / long term indication is included. In addition, in another implementation, ARI can be set to index a resource within the entire band
Petition 870190089475, of 10/09/2019, p. 45/91
39/59 of UL. In other words, the UE 100 can derive the subband based on the index. Additionally, if mirror hopping or some other hop (for example, jump based on deviation) is enabled for PUCCH, the jump operation can be derived based on the resource in the subband since the operation skip can be set on a subband basis. In addition, in another implementation, the ARI values can be configured separately for cross-partition and same partition programming configurations. For example, a first set of four possible ARI-indexed resources can be used for programming the same partition, while a second set of four possible ARI-indexed resources can be used for cross-partition programming.
[0089] In an implementation, the ACK payload size, resource index, etc. can be dynamically changed. For example, the ACK payload can be dynamically changed to a 1-bit ACK, CBG-based multibit ACK or a HARQ group-based multibit ACK. As a result, the number of RBs may be different based on the size of the payload, confirm discussed in greater detail with reference to Figure 7. In an additional example, the resource index can be dynamically changed, which may include short burst indication / long, deviation / subband index, resource pool index and / or index within the resource pool / subband.
[0090] Thus, as described above, the communications component 150 determines
Petition 870190089475, of 10/09/2019, p. 46/91
40/59
ACK / NACK on UE 110 from a set of UE-specific resources and transmit ACK / NACKs or other UCIs to gNB 110.
[0091] Referring to Figure 7, for example, a method 700 of wireless communication including determining ACK / NACK resources from multiple sets of uplink control information (UCI) resources in UE 110 according to aspects described above is disclosed.
[0092] For example, in 710, method 700 includes receiving, from a gNB, a radio resource control (RRC) configuration indicating multiple sets of UE-specific uplink control (UCI) information resources, which are subsets of a gNB resource pool. For example, in one aspect, the UE 110 and / or the modem 140 can execute the communications component 150 and / or the RRC / PDCCH 152 receiving component to receive the RRC configuration from gNB 105. The RRC configuration can contain information that directs or otherwise links the UE to multiple sets of UCIs in the gNB resource pool. The UCI subsets of the gNB resource pool assigned to the UE may be specific to the UE, for example, to avoid collisions with other transmissions from the UE, and may indicate suitable payload size ranges for each of the multiple UCI subsets specific to the EU.
[0093] Furthermore, in 720, method 700 includes determining, in the UE, a size of a payload for an UCI to be transmitted in a physical uplink control channel (PUCCH). For example, in one aspect, UE 110 and / or modem 140 can perform communications component 150
Petition 870190089475, of 10/09/2019, p. 47/91
41/59 and / or the resource determination component of ACK / NACK 154 to determine the size, or number of bits, of a UCI payload that the UE intends to transmit with an upcoming PUCCH.
[0094] Optionally, in 730, method 700 may include receiving, from gNB, a PDCCH including a corresponding ACK / NACK resource configuration. For example, in one aspect, UE 110 and / or modem 140 may perform communications component 150 and / or RRC / PDCCH 152 receiving component to receive one or more PDCCHs from gNB 105. Each PDCCH can include one ACK / NACK resource configuration, which indicates to UEs, for example, UE 110, the ACK / NACK resources of the UE-specific UCI resource sets indicated in the RRC configuration to be used by the UE 110 to transmit ACK / NACKs at PUCCH. For example, in one aspect, the configuration of ACK / NACK resources can be an ARI. In some respects, the ACK / NACK resource configuration includes a positive acknowledgment resource indicator (ARI), and an UCI comprises a positive ACK acknowledgment or a NACK.
[0095] Furthermore, in 740, method 700 includes determining, in the UE, a set of UE-specific UCI resources selected from the multiple sets of UE-specific resources to transmit a UCI in PUCCH based, at least on part, in the size of the UCI payload. For example, in one aspect, UE 110 and / or modem 140 may perform communications component 150 and / or ACK / NACK resource determination component 154 to determine one or more ACK / NACK resources from one of multiple sets
Petition 870190089475, of 10/09/2019, p. 48/91
42/59 of UCI resources based, at least in part, on the determined payload size. The communications component 150 and / or the resource determination component of ACK / NACK 154 can identify payload intervals associated with each of the multiple sets of UCI resources. For example, but without limitation, a first set of resources can be used for payloads ranging in size from 1 bit to 2 bits, while a second set of resources can be used with payloads ranging in size from 3-12 bits. The communications component 150 and / or the resource determination component of ACK / NACK 154 can identify which of the payload size ranges overlap with the determined payload size. That is, the UE 110 can determine whether the determined payload size is included in any of the identified payload size ranges. The UE 110 can select one of multiple UCI resource sets having a payload size range within which the given payload size is included. In another example, but without limitation, a given 8-bit payload size could be transmitted with resources from any of the resource sets mentioned above, but a 4-bit payload size could only be transmitted with resources from the first set of resources.
[0096] In some respects, determining the selected UE's specific UCI resource set may further include selecting one or more resources within the selected UE's specific UCI resource set based on implicit and / or explicit mapping. For example, such
Petition 870190089475, of 10/09/2019, p. 49/91
43/59 aspects may include receiving a positive confirmation resource indicator (ARI), and mapping to the one or more resources within the UE-specific UCI resource set selected based on an ARI value. Thus, some aspects may include receiving an ARI and selecting one or more resources within the UE-specific UCI resource set selected based on the ARI.
[0097] In some respects, the ARI includes a resource index and thus determining the set of specific UCI resources of the selected UE may further include selecting a subband associated with one or more resources based on the resource index . For example, [0098] In some respects, in response to receiving the ARI, determining the set of UCI resources specific to the selected UE may further include selecting, based on the ARI, a first group of one or more resources within the set of specific UCI resources of the selected UE for programming the same partition or a second group of one or more resources within the set of specific UCI resources of the selected UE for cross-partition programming. In some respects, determining one or more ACK / NACK resources from the UE-specific resource set is based, at least in part, on cross-partition programming information, and PDCCHs from different partitions have ARIs of equal value .
[0099] Optionally, at 750, method 700 may include transmitting an UCI through the set of UE-specific UCI resources selected in the PUCCH. For example, in one aspect, the UE 110 and / or modem 140 can perform the
Petition 870190089475, of 10/09/2019, p. 50/91
44/59 communications component 150 and / or the transmission component of ACK / NACK 156 to transmit an UCI, for example, an ACK / NACK to a PDSCH, using the UE-specific UCI resource set selected in the PUCCH.
[0100] In aspects implementing optional block 730, the specific ACK / NACK features to be used within each of the multiple UCI resource sets can be determined based, at least in part, on the ACK / NACK configuration received within the PDCCH. The UE 110 and / or the ACK / NACK resource determination component 154 can determine the ACK / NACK resources based, at least in part, on the ACK / NACK configuration. The ACK / NACK configuration can include a positive confirmation feature indicator (ARI) specifically indicating which exact features of a selected UCI feature set (for example, a selected subset of multiple feature sets within the specific feature set of the UE) should be used by UE 110 when transmitting ACK / NACKs. Thus, once the UE 110 has selected one of multiple UCI resource sets based on payload size, the UE 110 can then use the ACK / NACK setting to select specific ACK / NACK resources. of the UCI resource set for use in transmitting the ACK / NACK within the PUCCH.
[0101] In an additional example, the payload size may be different when combined with other UCIs. For example, when combined with a channel quality indicator (CQI), the payload size may be different since the CQI may have different information
Petition 870190089475, of 10/09/2019, p. 51/91
45/59 beam related. In addition, the ACK payload size may be different. For example, if a UE is supposed to transmit 10 ACK bits, after combining with CQI, the UE may be able to transmit only 3 ACK bits. In these scenarios, aggregation of ACKs can be used to join the ACK bit, or a subset of bits can be transmitted and the remaining ACK bits can be transmitted later. In addition, the initial resource block and the number of RBs and PUCCH formats (dependent on payload size) can be explicitly configured.
[0102] With reference to Figure 8, for example, a method 800 of wireless communication including determining ACK / NACK capabilities in gNB 105 according to the aspects described above is disclosed.
[0103] For example, in 805, method 800 includes transmitting a radio resource control (RRC) configuration to a UE indicating a set of specific UE resources, which is a subset of a gNB resource pool . For example, in one aspect, gNB 105 and / or modem 180 may perform communications component 190 to transmit the RRC configuration to the UE 110. The RRC configuration may contain information that directs or otherwise links the UE to a subset of the gNB resource pool. The subset of the gNB resource pool assigned to the UE can be specific to the UE. The gNB 105 can select a set of resources to assign to the UE using a variety of techniques. For example, in an implementation, gNB can select a set of resources by identifying resources
Petition 870190089475, of 10/09/2019, p. 52/91
46/59 available randomly from the gNB resource pool. Alternatively, in an implementation, gNB can select resources from the next available resource block in the gNB resource pool. In yet another implementation, gNB can select blocks of contiguous resources from the grouping of gNB resources. The gNB can allocate resources to the UEs, so that the probability of any of the UEs being allocated to the same resource is small.
[0104] For example, there may be a total of 200 PUCCH resources and a total of 100 UEs, with each UE having 16 resources in its resource pool. The gNB can randomly select 16 out of 200 PUCCH resources for each UE (with some of the 16 being a short PUCCH resource and the rest for a long PUCCH) as the set of resources to be identified in the RRC configuration. In a particular partition, if the 10 out of 100 UEs need to transmit PUCCH, the gNB can select one of the 16 resources in that UE resource set so that the likelihood of either of the two UEs using the same resource is minimized.
[0105] For example, in 810, method 800 includes transmitting a physical downlink control channel (PDCCH) to the UE including a corresponding ACK / NACK resource configuration. In some cases, the transmitted PDCCH can be one of one or more PDCCHs, each including a corresponding ACK / NACK resource configuration. For example, in one aspect, the gNB 105 and / or modem 180 may perform the communications component 190 and / or the PDCCH 192 transmission component to transmit one or more
Petition 870190089475, of 10/09/2019, p. 53/91
47/59
PDCCHs of the gNB 105, each including a corresponding ACK / NACK resource configuration. As described above, each PDCCH can include an ACK / NACK resource configuration that indicates to UEs, for example, UE 110, the ACK / NACK resources from the set of specific UE resources indicated in the RRC configuration to be used by UE 110 to transmit ACK / NACKs or other UCIs in the PUCCH. The configuration of ACK / NACK resources can include a positive confirmation resource indicator (ARI). In addition, ARI can be a multilevel resource index that includes one or more subband indices and one or more resource identifiers that identify at least one resource corresponding to each subband identified by one or more subband indices. band. In addition, one or more of the PDCCHs can identify one or more resource elements associated with a shared physical downlink channel (PDSCH) to be used to send user data to the UE 110.
[0106] For example, in 815, method 800 includes transmitting user data to the UE on a shared physical downlink channel (PDSCH). For example, in one aspect, gNB 105 and / or modem 180 may run communications component 190 to transmit user data from gNB 105 to UE 110 on one or more PDSCH resource elements as identified in control information, such as the PCCCH.
[0107] For example, in 820, method 800 may include receiving, from the UE, an ACK / NACK for user data transmitted in the PDSCH on at least one ACK / NACK resource determined by the UE based, at least in part ,
Petition 870190089475, of 10/09/2019, p. 54/91
48/59 in the configuration of ACK / NACK resources. For example, in one aspect, the gNB 105 and / or modem 180 can perform the communications component 190 and / or the ACK / NACK receive component 194 to receive an ACK / NACK doUE
110. gNB 104 can receive an ACK / NACK for user data on the PDSCH transmitted by gNB 105 to confirm whether UE 110 has properly received the signal, for example, user data.
[0108] Referring to Figure 9, for example, a 900 wireless communication method including determining ACK / NACK resources from multiple sets of uplink control information (UCI) resources in gNB 105 according to aspects described above is disclosed.
[0109] For example, in 910, method 900 includes transmitting to a UE a radio resource control (RRC) configuration indicating multiple sets of UE-specific uplink control (UCI) information resources, which are subsets of a gNB resource pool. For example, in one aspect, gNB 105 and / or modem 180 may run communications component 180 to transmit the RRC configuration from gNB 105 to UE 110. The RRC configuration may contain information that directs or otherwise binds the UE to multiple sets of UCIs in the gNB resource pool. The UCI subsets of the gNB resource pool assigned to the UE may be specific to the UE, for example, to avoid collisions with other transmissions from the UE, and may indicate suitable payload size ranges for each of the multiple UCI subsets specific to the EU. In some implementations, gNB 105
Petition 870190089475, of 10/09/2019, p. 55/91
49/59 can select resource sets for assignment to the UE based on random selection, selection of contiguous resource blocks and / or selection of the following available resource blocks.
[0110] Optionally, for example, in 920, method 900 may include transmitting a PDCCH to the UE including a corresponding ACK / NACK resource configuration. For example, in one aspect, gNB 105 and / or modem 180 may run communications component 190 and / or PDCCH 192 transmission component to transmit one or more PDCCHs from gNB 105 to UE 110. Each PDCCH may include an ACK / NACK resource configuration, which indicates to UEs, for example, UE 110, the ACK / NACK resources of the UE-specific UCI resource sets indicated in the RRC configuration to be used by the UE 110 to transmit ACK / NACKs at PUCCH. In addition, in some respects, the PDCCH includes one of a plurality of different types of format, where each of the plurality of format types corresponds to a different subset of the multiple sets of specific UE resources.
[0111] For example, in 930, method 900 may include receiving an UCI in a set of UE-specific UCI resources selected by the UE from multiple sets of UE-specific UCI resources based on a payload size of the UCI, in a PUCCH. For example, in one aspect, gNB 105 and / or modem 180 can execute communications component 100 and / or the receiving component of ACK / NACK 194 to receive a UCI, for example, an ACK / NACK for a PDSCH using the feature set
Petition 870190089475, of 10/09/2019, p. 56/91
50/59 of specific UCIs of the UE selected in the PUCCH. In some implementations, the UE-specific feature set can be selected by the UE 110 based on a UCI payload size and / or based on the transmitted ACK / NACK resource configuration.
[0112] With reference to Figure 10, an example of an implementation of a UE 110 may include a variety of components, some of which have already been described above, including components, such as one or more processors 1012, memory 1016 and transceiver 1002 in communication through one or more buses 1044, which can operate in conjunction with modem 140 and communications component 150 to determine ACK / NACK resources on UE 110. In addition, one or more processors 1012, modem 140, memory 1016 , transceiver 1002, front-end RF 1088 and one or more antennas 1065, can be configured to support voice and / or data calls (simultaneously or not simultaneously) in one or more radio access technologies.
[0113] In one aspect, one or more 1012 processors may include a modem 140 that uses one or more modem processors. The various functions related to the communications component 150 can be included in modem 140 and / or processors 1012 and, in one aspect, can be performed by a single processor, while in other aspects, different functions can be performed by a combination of two or more different processors. For example, in one aspect, the one or more 1012 processors may include any or any combination of a modem processor, or a baseband processor, or a digital signal processor, or a video processor.

51/59 transmission, or a receiver processor, or a transceiver processor associated with transceiver 1002. In other respects, some of the features of one or more processors 1012 and / or modem 140 associated with communications component 150 may be performed by transceiver 1002.
[0114] In addition, memory 1016 can be configured to store data used here and / or local versions of applications 1075 or communications component 150 and / or one or more of its subcomponents running on at least one 1012 processor. Memory 1016 may include any type of computer-readable medium usable by a computer or at least a 1012 processor, such as random access memory (RAM), read-only memory (ROM), tapes, magnetic disks, optical disks, volatile memory, non-volatile memory, and any combination thereof. In one aspect, for example, memory 1016 can be a non-transitory computer-readable storage medium that stores one or more computer executable codes defining the communications component 150 and / or one or more of its subcomponents, and / or data associated with them, when the UE 110 is operating at least one processor 1012 to execute the communications component 150 and / or one or more of its subcomponents.
[0115] Transceiver 1002 may include at least one receiver 1006 and at least one transmitter 1008. Receiver 1006 may include hardware code, firmware and / or software executable by a processor to receive data, the code comprising instructions and being stored in a memory (eg computer readable medium).
Petition 870190089475, of 10/09/2019, p. 58/91
52/59 receiver 1006 can be, for example, a radio frequency (RF) receiver. In one aspect, receiver 1006 can receive signals transmitted by at least one base station 105. Additionally, receiver 1006 can process such received signals, and can also obtain signal measurements, such as, but not limited to, Ec / Io, SNR, RSRP, RSSI etc. The transmitter 1008 may include hardware code, firmware and / or software executable by a processor to transmit data, the code comprising instructions and being stored in a memory (for example, computer readable medium). A suitable example of the 808 transmitter may include, but is not limited to, an RF transmitter.
[0116] Furthermore, in one aspect, the UE 110 may include an RF 1088 front end, which can operate in communication with one or more 1065 antennas and the 802 transceiver to receive and transmit radio transmissions, for example, wireless communications. wire transmitted by at least one base station 105 or wireless transmissions transmitted by UE 110. The RF 1088 front end can be communicatively coupled with one or more 1065 antennas and may include one or more 1090 low-noise amplifiers (LNAs), one or more switches 1092, one or more power amplifiers (PAs) 1098, and one or more filters 1096 for transmitting and receiving RF signals.
[0117] In one aspect, the LNA 1090 can amplify a signal received at a desired output level. In one respect, each LNA 1090 can have specified minimum and maximum gain values. In one aspect, the RF 1088 front end can use one or more 1092 switches to select one

53/59
Private LNA 1090 and its specified gain value based on a desired gain value for a particular application.
[0118] In addition, for example, one or more 1098 PA (s) can be used by the RF 1088 front end to amplify a signal to an RF output at a desired output power level. In one respect, each PA 1098 can have specified minimum and maximum gain values. In one aspect, the RF 1088 front end can use one or more 1092 switches to select a particular PA 1098 and its specified gain value based on a desired gain value for a particular application.
[0119] In addition, for example, one or more 1096 filters can be used by the RF 1088 front end to filter a received signal to obtain an incoming RF signal. Likewise, in one aspect, for example, a respective 1096 filter can be used to filter an output from a respective PA 1098 to produce an output signal for transmission. In one aspect, each 1096 filter can be connected to a specific LNA 1090 and / or PA 1098. In one aspect, the RF 888 front end can use one or more 1092 switches to select a transmit or receive path using a specified 1096, LNA 1090 and / or PA 1098 filter, based on a configuration as specified by transceiver 1002 and / or 1012 processor.
[0120] In this way, transceiver 1002 can be configured to transmit and receive wireless signals through one or more antennas 1065 through the RF 1088 front-end. In one aspect, transceiver 1002 can be tuned to operate at specified frequencies of
Petition 870190089475, of 10/09/2019, p. 60/91
54/59 so that UE 110 can communicate with, for example, one or more cells associated with one or more base stations 105. In one aspect, for example, modem 140 can configure transceiver 1002 to operate on a frequency power level based on the UE 110 configuration and communication protocol used by modem 140.
[0121] In one aspect, modem 140 can be a multiband-multimode modem, which can process digital data and communicate with transceiver 1002 so that digital data is sent and received using transceiver 1002. In one aspect, the modem 140 can be multiband and be configured to support multiple frequency bands for a specific communications protocol. In one aspect, modem 140 can be multimode and be configured to support multiple operating networks and communications protocols. In one aspect, modem 140 can control one or more components of UE 110 (e.g., RF 1088 front-end, transceiver 1002) to allow transmission and / or reception of network signals based on a specified modem configuration. In one aspect, the modem configuration can be based on the modem mode and the frequency band in use. In another aspect, the modem configuration can be based on base station information associated with the UE 110 as provided by the network during cell selection and / or cell reselection.
[0122] With reference to Figure 11, an example of a 105 base station implementation can include a variety of components, which have already been described in detail above, including components, such as one or more
