[0035] This disclosure provides apparatus, methods, processing systems, and computer-readable media for conveying sidelink feedback in interleaved frequency resources.

[0036] Some wireless communication systems (e.g., 5G New Radio (NR) systems and / or future wireless communication technologies) allow peer-to-peer communication, where User Equipment (UE) communicates directly with other UEs without the need for network entities (e.g., base stations) to relay such communication between UEs. This type of peer-to-peer (or device-to-device (D2D)) communication is often referred to as sidelink communication. Examples of sidelink communication include vehicle-to-vehicle (V2X) communication, where vehicles can communicate with other vehicles (referred to as vehicle-to-vehicle (V2V) communication), with UEs, roadside units (RSUs), etc. While some aspects can be discussed relative to V2X communication in V2X communication systems, it should be noted that these aspects are equivalent to other suitable types of sidelink communication systems. To address the rapidly growing demand for wireless data services, particularly for sidelink communication, some wireless communication systems (e.g., 5G NR systems) allow wireless services to be implemented in unlicensed or shared spectrum bands (e.g., the 4GHz, 5GHz, and 60GHz bands) as a way to increase wireless channel capacity.

[0037] Technical issues surrounding sidelink communication in unlicensed or shared spectrum include, for example, meeting certain regulatory requirements associated with communication on unlicensed or shared spectrum. Unlicensed spectrum is subject to certain regulatory restrictions, such as listen-before-speak procedures, maximum channel occupancy time, equivalent isotropic radiated power (EIRP), power spectral density (PSD), occupied channel bandwidth (OCB), frequency reuse, and / or dynamic frequency selection. For example, some regulatory bodies (e.g., the Federal Communications Commission (FCC) in the United States and the European Telecommunications Standards Institute (ETSI) in the European Union) specify a certain percentage of channel bandwidth that signal power is expected to occupy in unlicensed channels (e.g., between 70% and 100% for the 5 GHz band). Such specifications are referred to as occupied channel bandwidth and serve to prevent interference to other frequency channels. Furthermore, some regulatory bodies specify certain power limits for communication in unlicensed or shared spectrum, including limits on PSD and EIRP, to further mitigate interference. To meet the OCB, PSD, and EIRP specifications for communication in unlicensed spectrum, some wireless communication systems (e.g., 5G NR systems) may interleave frequency resources for certain communication channels, such as the Physical Side Link Control Channel (PSCCH) and / or the Physical Side Link Shared Channel (PSSCH). The interleaved frequency resources used for communication in unlicensed or shared spectrum extend the energy of communication across channels to meet various regulatory specifications, such as the OCB, EIRP, and PSD specifications.

[0038] To facilitate Hybrid Automatic Repeat Request (HARQ) feedback communication that meets regulatory requirements for unlicensed or shared spectrum, some wireless communication systems define frequency resource interleaving schemes for Physical Side Link Feedback Channel (PSFCH) communication to convey HARQ feedback, as further described herein. However, a technical challenge with interleaving schemes for PSFCH communication is that, for some wireless communication systems, it is unclear how to apply and configure these schemes across certain frequency resources, such as bandwidth portions (BWPs), resource pools, and resource block (RB) sets.

[0039] The aspects described herein overcome the aforementioned technical problems by providing various configurations of frequency resource interleaving modes for PSFCH communication. PSFCH configuration can indicate the use of a hybrid interleaving mode or a dedicated interleaving mode to convey HARQ feedback. A hybrid interleaving mode may include common interleaving of frequency resources shared by multiple UEs and one or more dedicated frequency resources (e.g., UE-specific frequency resources), while a dedicated interleaving mode may include dedicated interleaving of frequency resources (e.g., UE-specific frequency resources). Hybrid interleaving modes can be configured, for example, at various frequency resource levels across different portions of the BWP (e.g., resource pools and / or RB sets) across carrier bandwidth, as further described herein. In some cases, hybrid interleaving modes can be explicitly configured, for example, via Radio Resource Control (RRC) signaling. Explicit configuration can be via explicit indicators or values ​​included in the signaling configuring the hybrid interleaving mode. In some cases, hybrid interleaving modes can be implicitly configured. Implicit configuration can be via indicators missing in the signaling or based on indicators that explicitly indicate other content in the signaling. For example, a PSFCH configuration indicating the number of dedicated frequency resources in a hybrid interleaving mode at a specific frequency resource level can implicitly indicate that the hybrid interleaving mode is used for HARQ feedback communication on the PSFCH. In some respects, frequency resource interleaving modes can be applied to communication in unlicensed or shared spectrum.

[0040] The techniques described herein for communicating sidelink feedback in interleaved frequency resources can provide any of a variety of beneficial effects and / or advantages. These techniques can achieve improved wireless communication performance, such as reduced or mitigated interference, reduced signaling overhead, increased feedback channel capacity, and reduced HARQ feedback latency. The improved wireless communication performance can be attributed to the various configurations of frequency resource interleaving for HARQ feedback communication as described herein. These configurations can facilitate the efficient application of hybrid or dedicated interleaving modes, for example, due to reduced overhead resulting from various implicit indications of the configurations further described herein. Interleaved frequency resources can reduce or mitigate interference, for example, due to the energy required for cross-channel extended HARQ feedback communication. Hybrid interleaving modes can reduce signaling overhead, increase feedback channel capacity, and reduce HARQ feedback latency by allowing multiple UEs to share common interleaving of frequency resources and also access one or more dedicated frequency resources, thereby enabling dynamic channel load balancing, mitigating interference or noise, and increasing the reliability of HARQ feedback.

[0041] Unlicensed or shared spectrum refers to any frequency band that is not subject to license under regulatory practice, making that band open for use by any device and not just devices with a license to use a particular frequency band.

[0042] An introduction to wireless communication networks The techniques and methods described herein can be used in a variety of wireless communication networks. Although aspects herein may be described using terms commonly associated with 3G, 4G, 5G, 6G and / or other generations of wireless technologies, aspects of this disclosure are equally applicable to other communication systems and standards not explicitly mentioned herein.

[0043] Figure 1 An example of a wireless communication network 100 in which the aspects described herein can be implemented is depicted.

[0044] Generally, wireless communication network 100 includes various network entities (alternatively, network elements or network nodes). Network entities are typically communication devices and / or communication functions performed by communication devices (e.g., user equipment (UE), base station (BS), components of the BS, servers, etc.). Since such communication devices are part of wireless communication network 100 and facilitate wireless communication, they may be referred to as wireless communication devices. For example, various functions of the network and various devices associated with and interacting with the network may be considered network entities. Furthermore, wireless communication network 100 includes terrestrial aspects (such as terrestrial network entities (e.g., BS 102)) and non-terrestrial aspects (also referred to herein as non-terrestrial network entities) (such as satellite 140 and aircraft), which may include onboard network entities (e.g., one or more BSs) capable of communicating with other network elements (e.g., terrestrial BSs) and UEs.

[0045] In the depicted example, wireless communication network 100 includes BS 102, UE 104 and one or more core networks (such as Evolved Packet Core (EPC) 160 and 5G Core (5GC) network 190) that interoperate to provide communication services over various communication links, including wired and wireless links.

[0046] Figure 1Various example UEs 104 are described, which may more generally include: cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players, cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, Internet of Things (IoT) devices, always-on (AON) devices, edge processing devices, data centers, or other similar devices. UE 104 may also be more generally referred to as mobile devices, wireless devices, stations, mobile stations, subscriber stations, mobile subscriber stations, mobile units, subscriber units, wireless units, remote units, remote devices, access terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, and others.

[0047] BS 102 communicates wirelessly with UE 104 via communication link 120 (e.g., transmitting or receiving signals to or from UE 104). Communication link 120 between BS 102 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to BS 102 and / or downlink (DL) (also known as forward link) transmission from BS 102 to UE 104. In various aspects, communication link 120 may utilize multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity.

[0048] BS 102 may typically include: NodeB, enhanced NodeB (eNB), next-generation enhanced NodeB (ng-eNB), next-generation NodeB (gNB or gNodeB), access point, transceiver base station, radio base station, radio transceiver, transceiver functionality, transmit / receive point, and / or others. Each of BS 102 provides communication coverage for a corresponding coverage area 110, which may sometimes be referred to as a cell, and in some cases may overlap (e.g., a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of a macro cell). For example, BS may provide communication coverage for macro cells (covering a relatively large geographic area), pico cells (covering a relatively small geographic area, such as a stadium), femtocells (covering a relatively small geographic area (e.g., a home)), and / or other types of cells.

[0049] Generally, a cell can refer to a portion, partition, or segment of wireless communication coverage served by a network entity within a wireless communication network. A cell may have geographical characteristics (such as a geographical coverage area) and radio frequency characteristics (such as time and / or frequency resources dedicated to the cell). For example, a specific geographical coverage area may be covered by multiple cells employing different frequency resources (e.g., bandwidth portions) and / or different time resources. As another example, a specific geographical coverage area may be covered by a single cell. In some contexts (e.g., carrier aggregation scenarios and / or multi-connectivity scenarios), the terms "cell" or "serving cell" may refer to or correspond to a specific carrier frequency (e.g., component carrier) used for wireless communication, and "cell group" may refer to or correspond to multiple carriers used for wireless communication. For example, in a carrier aggregation scenario, a UE may communicate on multiple component carriers corresponding to multiple (serving) cells in the same cell group, and in a multi-connectivity (e.g., dual-connectivity) scenario, a UE may communicate on multiple component carriers corresponding to multiple cell groups.

[0050] Although BS 102 is described as a single communication device in various aspects, it can be implemented in various configurations. For example, to give a few examples, one or more components of the base station can be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC. In another example, various aspects of the base station can be virtualized. More generally, a base station (e.g., BS 102) can include components located at a single physical location or components located at various physical locations. In examples where the base station includes components located at various physical locations, the various components can each perform functions, such that the various components collectively achieve functionality similar to a base station located at a single physical location. In some aspects, a base station including components located at various physical locations can be referred to as a decomposed radio access network architecture (such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture). Figure 2 An example decomposed base station architecture is depicted and described.

[0051] Different BSs 102 within the wireless communication network 100 can also be configured to support different radio access technologies (such as 3G, 4G, and / or 5G). For example, a BS 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). A BS 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) can interface with 5GC 190 via a second backhaul link 184. BSs 102 can communicate directly or indirectly (e.g., via EPC 160 or 5GC 190) on a third backhaul link 134 (e.g., X2 interface), which can be wired or wireless.

[0052] Wireless communication network 100 can subdivide the electromagnetic spectrum into various categories, bands, channels, or other characteristics. In some aspects, subdivision is provided based on wavelength and frequency, where frequency may also be referred to as carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 410MHz-7125MHz, which is often (interchangeably) referred to as “sub-6GHz”. Similarly, 3GPP currently defines frequency range 2 (FR2) as including 24,250MHz to 71,000MHz, which is sometimes (interchangeably) referred to as “millimeter wave” (“mmW” or “mmWave”). In some cases, FR2 can be further defined according to subranges (such as a first subrange FR2-1 including 24,250MHz-52,600MHz and a second subrange FR2-2 including 52,600MHz-71,000MHz). Base stations configured to communicate using mmWave / near mmWave radio bands (e.g., mmWave base stations such as BS 180) can utilize beamforming (e.g., 182) with UEs (e.g., 104) to improve path loss and range.

[0053] The communication link 120 between BS 102 and, for example, UE 104 can be via one or more carriers, which may have different bandwidths (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz and / or other MHz) and may be aggregated in various ways. The carriers may be adjacent to each other or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL).

[0054] Compared to lower-frequency communication, communication using higher frequency bands may have higher path loss and shorter range. Therefore, some base stations (e.g., Figure 1 The beamforming 182 of the BS 180 (180) with the UE 104 can be used to improve path loss and range. For example, the BS 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming. In some cases, the BS 180 may transmit beamformed signals to the UE 104 in one or more transmit directions 182''. The UE 104 may receive beamformed signals from the BS 180 in one or more receive directions 182''. The UE 104 may also transmit beamformed signals to the BS 180 in one or more transmit directions 182''. The BS 180 may also receive beamformed signals from the UE 104 in one or more receive directions 182''. The BS 180 and UE 104 may then perform beamforming training to determine the optimal receive and transmit directions for each of the BS 180 and UE 104. It is worth noting that the transmit and receive directions of the BS 180 may be the same or different. Similarly, the sending and receiving directions of UE 104 can be the same or different.

[0055] The wireless communication network 100 further includes a Wi-Fi AP 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, unlicensed spectrum in 2.4 GHz and / or 5 GHz.

[0056] Some UEs 104 may use device-to-device (D2D) communication link 158 to communicate with each other. The D2D communication link 158 may use one or more sidelink channels, such as physical sidelink broadcast channel (PSBCH), physical sidelink discovery channel (PSDCH), physical sidelink shared channel (PSSCH), physical sidelink control channel (PSCCH), and / or physical sidelink feedback channel (PSFCH).

[0057] EPC 160 may include various functional components, including: Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and / or Packet Data Network (PDN) Gateway 172, as in the illustrated example. MME 162 may communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Generally, MME 162 provides bearer and connectivity management.

[0058] Generally, user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP services 176, which may include, for example, the Internet, intranets, IP Multimedia Subsystem (IMS), packet-switched (PS) streaming services, and / or other IP services.

[0059] The BM-SC 170 provides functionality for MBMS user service dispatch and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, can be used to authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and / or can be used to schedule MBMS transmissions. The MBMS gateway 168 can be used to distribute MBMS services to BS 102 belonging to a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and / or can be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0060] 5GC 190 may include various functional components, including: Access and Mobility Management Function (AMF) 192, other AMFs 193, Session Management Function (SMF) 194, and User Plane Function (UPF) 195. AMF 192 can communicate with Unified Data Management (UDM) 196.

[0061] AMF 192 is the control node that handles signaling between UE 104 and 5GC 190. AMF 192 provides services such as Quality of Service (QoS) flow and session management.

[0062] Internet Protocol (IP) packets are transmitted via UPF 195, which connects to IP service 197 and provides the UE with IP address allocation and other functions for 5GC 190. IP service 197 may include, for example, the Internet, intranet, IMS, PS streaming service, and / or other IP services.

[0063] In various aspects, to give a few examples, network entities or network nodes can be implemented as aggregated base stations, decomposed base stations, components of base stations, integrated access and backhaul (IAB) nodes, relay nodes, and sidelink nodes.

[0064] Figure 2An example decomposed base station 200 architecture is depicted. The decomposed base station 200 architecture may include one or more central units (CUs) 210, which may communicate directly with the core network 220 via a backhaul link, or indirectly with the core network 220 through one or more decomposed base station units, such as a near real-time (near-RT) RAN Intelligent Controller (RIC) 225 via an E2 link, or a non-real-time (non-RT) RIC 215 associated with a Service Management and Orchestration (SMO) framework 205, or both. CUs 210 may communicate with one or more distributed units (DUs) 230 via corresponding midhaul links (such as F1 interfaces). DUs 230 may communicate with one or more radio units (RUs) 240 via corresponding fronthaul links. RUs 240 may communicate with a corresponding UE 104 via one or more radio frequency (RF) access links. In some specific implementations, UE 104 may be served simultaneously by multiple RUs 240.

[0065] Each unit in a cell (e.g., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO frame 205) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cell, or an associated processor or controller providing instructions to the unit's communication interface, may be configured to communicate with one or more other units via transmission media. For example, these units may include wired interfaces configured to receive signals or transmit signals to one or more other units via wired transmission media. Additionally or alternatively, a unit may include a wireless interface that may include a receiver, transmitter, or transceiver (such as a radio frequency (RF) transceiver) configured to receive signals on a wireless transmission medium or transmit signals to one or more other units, or both.

[0066] In some aspects, CU 210 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by CU 210. CU 210 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP)), control plane functions (e.g., Central Unit-Control Plane (CU-CP)), or combinations thereof. In some implementations, CU 210 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, CU-UP units can communicate bidirectionally with CU-CP units via an interface such as an E1 interface. CU 210 can be implemented to communicate with DU 230 for network control and signaling, as needed.

[0067] DU 230 may correspond to a logic unit that includes one or more base station functions for controlling the operation of one or more RU 240s. In some aspects, DU 230 may at least partially host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) according to functional splits (such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 230 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signaling with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210.

[0068] Lower-layer functionality can be implemented by one or more RU 240s. In some deployments, an RU240 controlled by a DU 230 may correspond to a logical node that hosts RF processing functions or low-PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, or both, based at least in part on functional decomposition (such as lower-layer functional decomposition). In such architectures, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UE 104s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration allows the DU 230 and CU 210 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0069] SMO framework 205 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 205 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, SMO framework 205 can be configured to interact with cloud computing platforms such as Open Cloud (O-Cloud) 290 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some specific implementations, SMO framework 205 may communicate with the hardware aspects of the 4G RAN (such as Open eNB (O-eNB) 211) via the O1 interface. Additionally, in some implementations, the SMO framework 205 may communicate directly with one or more DU 230s and / or one or more RU 240s via the O1 interface. The SMO framework 205 may also include a non-RTRIC 215 configured to support the functionality of the SMO framework 205.

[0070] The non-RT RIC 215 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 225. The non-RT RIC 215 can be coupled to or communicate with the near-RT RIC 225, such as via an A1 interface. The near-RT RIC 225 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and actions, connecting one or more CU 210s, one or more DU 230s, or both, and O-eNBs to the near-RT RIC 225.

[0071] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 225, the non-RT RIC 215 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 225 and may be received from non-network data sources or network functions at the SMO framework 205 or the non-RT RIC 215. In some examples, the non-RT RIC 215 or the near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 205 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0072] Figure 3 Various aspects of examples BS 102 and UE 104 are described.

[0073] Generally, BS 102 includes various processors (e.g., 318, 320, 330, 338, and 340), antennas 334a-334t (collectively referred to as 334), transceivers 332a-332t (collectively referred to as 332) including modulators and demodulators, and other aspects that enable the wireless transmission of data (e.g., data source 312) and the wireless reception of data (e.g., data sink 314). For example, BS 102 can transmit and receive data between BS 102 and UE 104. BS 102 includes a controller / processor 340 that can be configured to implement the various functions described herein related to wireless communication.

[0074] Generally, UE 104 includes various processors (e.g., 358, 364, 366, 370, and 380), antennas 352a-352r (collectively referred to as 352), transceivers 354a-354r (collectively referred to as 354) including modulators and demodulators, and other aspects that enable the wireless transmission of data (e.g., retrieved from data source 362) and the wireless reception of data (e.g., provided to data sink 360). UE 104 includes a controller / processor 380 that can be configured to implement the various functions described herein related to wireless communication.

[0075] Regarding example downlink transmission, BS 102 includes a transmission processor 320 that can receive data from data source 312 and control information from controller / processor 340. This control information may be for a Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical Hybrid Automatic Repeat Request (HARQ) Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Group Common PDCCH (GC PDCCH), and / or others. In some examples, this data may be for a Physical Downlink Shared Channel (PDSCH).

[0076] The transmitter processor 320 can process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. The transmitter processor 320 can also generate reference symbols (such as those for the primary synchronization signal (PSS), secondary synchronization signal (SSS), PBCH demodulation reference signal (DMRS), and channel state information reference signal (CSI-RS)).

[0077] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, and / or reference symbols where applicable, and can provide the output symbol stream to the modulators (MODs) in transceivers 332a-332t. Each modulator in transceivers 332a-332t can process its corresponding output symbol stream to obtain an output sample stream. Each modulator can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signal from the modulators in transceivers 332a-332t can be transmitted via antennas 334a-334t respectively.

[0078] To receive downlink transmissions, UE 104 includes antennas 352a-352r that receive downlink signals from BS 102 and provide the received signals to demodulators (DEMODs) in transceivers 354a-354r respectively. Each demodulator in transceivers 354a-354r can adjust (e.g., filter, amplify, down-convert, and digitize) the corresponding received signal to obtain an input sample. Each demodulator can further process the input sample to obtain the received symbols.

[0079] The RX MIMO detector 356 acquires received symbols from all demodulators in transceivers 354a-354r, performs MIMO detection on the received symbols where applicable, and provides the detected symbols. The receive processor 358 processes (e.g., demodulates, deinterleaves, and decodes) the detected symbols, provides the decoded data for UE 104 to data sink 360, and provides the decoded control information to controller / processor 380.

[0080] Regarding the example uplink transmission, UE 104 further includes a transmission processor 364 that receives and processes data from data source 362 (e.g., for PUSCH) and control information from controller / processor 380 (e.g., for Physical Uplink Control Channel (PUCCH)). Transmission processor 364 can also generate reference symbols for reference signals (e.g., for Sounding Reference Signal (SRS)). Symbols from transmission processor 364 may be pre-decoded by TX MIMO processor 366, where applicable, further processed by modulators in transceivers 354a-354r (e.g., for SC-FDM), and transmitted to BS 102.

[0081] At BS 102, uplink signals from UE 104 can be received by antennas 334a-334t, processed by demodulators in transceivers 332a-332t, detected where applicable by RX MIMO detector 336, and further processed by receiver processor 338 to obtain decoded data and control information transmitted by UE 104. Receiver processor 338 can provide the decoded data to data sink 314 and the decoded control information to controller / processor 340.

[0082] Memory 342 and memory 382 can store data and program code for BS 102 and UE 104, respectively.

[0083] Scheduler 344 can schedule UE to transmit data on the downlink and / or uplink.

[0084] In various respects, BS 102 can be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, "transmitting" can refer to various mechanisms that output data, such as from data source 312, scheduler 344, memory 342, transmit processor 320, controller / processor 340, TX MIMO processor 330, transceiver 332a-332t, antenna 334a-334t, and / or other aspects described herein. Similarly, "receiving" can refer to various mechanisms that acquire data, such as from antenna 334a-334t, transceiver 332a-332t, RX MIMO detector 336, controller / processor 340, receive processor 338, scheduler 344, memory 342, and / or other aspects described herein.

[0085] In various respects, UE 104 can also be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” can refer to various mechanisms that output data, such as from data source 362, memory 382, ​​transmit processor 364, controller / processor 380, TX MIMO processor 366, transceiver 354a-354t, antenna 352a-352t, and / or other aspects described herein. Similarly, “receiving” can refer to various mechanisms that acquire data, such as from antenna 352a-352t, transceiver 354a-354t, RX MIMO detector 356, controller / processor 380, receive processor 358, memory 382, ​​and / or other aspects described herein.

[0086] In some respects, the processor can be configured to perform various operations (such as those associated with the methods described herein) and to send (output) data to or receive data from another interface configured to send or receive data, respectively.

[0087] In various aspects, artificial intelligence (AI) processors 318 and 370 may perform AI processing for BS 102 and / or UE 104, respectively. AI processor 318 may include AI accelerator hardware or circuitry, such as one or more neural processing units (NPUs), one or more neural network processors, one or more tensor processors, one or more deep learning processors, etc. AI processor 370 may also include AI accelerator hardware or circuitry. For example, AI processor 370 may perform AI-based beam management, AI-based channel state feedback (CSF), AI-based antenna tuning, and / or AI-based positioning (e.g., Global Navigation Satellite System (GNSS) positioning). In some cases, AI processor 318 may use hardware-accelerated AI inference and / or AI training to process feedback (e.g., CSF) from UE 104. AI processor 318 may, for example, use hardware-accelerated AI inference associated with a compressed CSF from UE 104 to decode the CSF. In some cases, AI processor 318 may perform certain RAN-based functions, including, for example, network planning, network performance management, energy-efficient network operation, etc.

[0088] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes the use of wireless communication networks (such as Figure 1 All aspects of the data structure of the wireless communication network 100.

[0089] Specifically, Figure 4A Figure 400 is an example of the first subframe within a 5G (e.g., 5G NR) frame structure. Figure 4B Figure 430 illustrates an example of a DL channel within a 5G subframe. Figure 4C Figure 450 illustrates an example of the second subframe within a 5G frame structure, and Figure 4D Figure 480 illustrates an example of a UL channel within a 5G subframe.

[0090] Wireless communication systems can utilize Orthogonal Frequency Division Multiplexing (OFDM) with a cyclic prefix (CP) on both the uplink and downlink. Such systems can also support half-duplex operation using Time Division Duplex (TDD). OFDM and Single-Carrier Frequency Division Multiplexing (SC-FDM) will (e.g., as...) Figure 4B and Figure 4D The system bandwidth (as depicted in the text) is divided into multiple orthogonal subcarriers. Each subcarrier can be modulated with data. Modulation symbols can be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0091] Wireless communication frame structures can be frequency division duplex (FDD), where for a specific set of subcarriers, subframes within that set are dedicated to either deep (DL) or ultra-low (UL). Wireless communication frame structures can also be time division duplex (TDD), where for a specific set of subcarriers, subframes within that set are dedicated to both DL and UL.

[0092] exist Figure 4A and Figure 4C In this example, the wireless communication frame structure is TDD, where D stands for DL, U for UL, and X is flexibly used between DL and UL. The UE can be configured using the time slot format via the received Time Slot Format Indicator (SFI) (dynamically via DL Control Information (DCI) or semi-statically / statically via Radio Resource Control (RRC) signaling). In the depicted example, a 10ms frame is divided into 10 equal-sized 1ms subframes. Each subframe may include one or more time slots. In some examples, each time slot may include 12 or 14 symbols, depending on the Cyclic Prefix (CP) type (e.g., 12 symbols per time slot for extended CP, or 14 symbols per time slot for regular CP). Subframes may also include micro-time slots, which typically have fewer symbols than the entire time slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0093] In some respects, the number of time slots within a subframe (e.g., the time slot duration within a subframe) is based on a parameter set that defines the frequency-domain subcarrier spacing and symbol duration, as further described herein. In some respects, given a parameter set μ, there are 2... μ The number of time slots is 1. Therefore, parameter sets (µ) 0 through 6 allow for 1, 2, 4, 8, 16, 32, and 64 time slots per subframe, respectively. In some cases, extended CP (e.g., 12 symbols per time slot) can be used with specific parameter sets (e.g., parameter set 2, allowing 4 time slots per subframe). Subcarrier spacing and symbol length / duration are functions of the parameter sets. The subcarrier spacing can be equal to... kHz, where μ is the parameter set from 0 to 6. For example, parameter set Corresponding to a subcarrier spacing of 15 kHz, and the parameter set This corresponds to a subcarrier spacing of 960 kHz. The symbol length / duration is negatively correlated with the subcarrier spacing. Figure 4A , Figure 4B , Figure 4C and Figure 4D It provides a slot format with 14 symbols per slot (e.g., regular CP) and a parameter set with 4 slots per subframe. An example. In this case, the slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

[0094] like Figure 4A , Figure 4B , Figure 4C and Figure 4D As depicted, the resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) (also known as a physical RB (PRB)) extending for, for example, 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme, including, for example, quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM).

[0095] like Figure 4A As illustrated in the example, some REs in the RE carry information for the UE (e.g., Figure 1 and Figure 3 The reference (pilot) signal (RS) for the UE (104) may include a demodulation RS (DMRS) and / or a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0096] Figure 4B Examples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs), each CCE comprising, for example, nine RE groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0097] The Primary Synchronization Signal (PSS) can be located within symbol 2 of a specific subframe of the frame. The PSS is generated by the UE (e.g., Figure 1 and Figure 3 104) is used to determine subframe / symbol timing and physical layer identifier.

[0098] The secondary synchronization signal (SSS) can be located in symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the physical layer cell identifier group number and radio frame timing.

[0099] Based on the Physical Layer Identifier and Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DMRS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block. The MIB provides the System Frame Number (SFN) and the number of Restricted Frames (RBs) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information (such as System Information Blocks (SIBs)) not transmitted via the PBCH, and / or paging messages.

[0100] like Figure 4CAs illustrated, some REs in the REs carry DMRS for channel estimation at the base station (indicated as R for a particular configuration, but other DMRS configurations are possible). The UE can transmit DMRS for PUCCH and DMRS for PUSCH. PUSCH DMRS can be transmitted, for example, in the first or second symbol before the PUSCH. PUCCH DMRS can be transmitted in different configurations depending on whether a short or long PUCCH is being transmitted and depending on the specific PUCCH format used. UE104 can transmit a sounding reference signal (SRS). SRS can be transmitted, for example, in the last symbol of a subframe. SRS can have a comb structure, and the UE can transmit SRS on one of the comb teeth. SRS can be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0101] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), pre-decoding matrix indicators (PMI), rank indicators (RI), and HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCI.

[0102] Example HARQ feedback In some cases, wireless communication systems may support data transmission with Hybrid Automatic Repeat Request (HARQ) to provide forward error correction in addition to automatic retransmission of data that cannot be decoded at the receiver. For example, in a sidelink context, a transmitter (e.g., a first UE) may transmit an initial transmission of data to a receiver (e.g., a second UE), and if the data cannot be decoded at the receiver, the transmitter may transmit one or more retransmissions of the data (such as transport blocks (TBs), code block groups (CBGs), or one or more code blocks) until the data is successfully decoded at the receiver, or until the maximum number of retransmissions of data has been completed at the transmitter, or until some other termination condition is encountered. The data may include TBs, codewords, data blocks, etc.

[0103] When a retransmission is received, the receiver may combine all or some of the received transmissions (including the initial transmission and retransmissions) to attempt to decode the data. In some cases, if the data is successfully decoded, the receiver may send an acknowledgment (ACK), or if the data is incorrectly decoded or unsuccessfully decoded, the receiver may send a negative ACK (NACK). HARQ feedback may include an ACK or NACK associated with a transmission (e.g., the initial transmission or retransmission). If a NACK is received, the transmitter may retransmit the data, while if an ACK is received, the transmitter may terminate the data transmission. In some cases, if the transmitter fails to receive an ACK within a specific time period, the transmitter may retransmit the data. The transmitter may utilize forward error correction and / or redundancy information to process (e.g., encoding and modulation) the data, and the forward error correction and / or redundancy information may be selected so that the data can be successfully decoded with a high probability. In some cases, data transmission (e.g., a transport block) may be segmented into code blocks (CBs), and retransmissions may be triggered based on CBGs (e.g., a set of code blocks). Retransmissions may include a portion of the initial transmission, such as a group of code blocks from a transport block.

[0104] Sidelink communication uses the Physical Sidelink Feedback Channel (PSFCH) to convey HARQ feedback. Sidelink HARQ feedback can be sent on the PSFCH as either unicast or multicast. In some cases configurable for unicast and / or multicast, the PSFCH is used to convey ACK or NACK using resources dedicated to a single PSFCH-transmitting UE. In some cases configurable for multicast, the PSFCH is used to send NACK on resources that can be shared by multiple PSFCH-transmitting UEs (e.g., common resources), or to not send PSFCH signal.

[0105] Example V2X communication Figure 5 A diagram illustrating an example V2X system 500 is provided. In this example, the V2X system includes multiple UEs 504a to 504d (collectively referred to as UE 504) communicating with each other via UE-to-UE direct communication (often referred to as sidelink communication). In some cases, the wireless communication channel used for UE-to-UE direct communication is referred to as a PC5 interface. The V2X system 500 may further include network entity 502, such as BS 102 and / or any of its decomposed network entities, for example, as described herein with respect to... Figure 1 and Figure 2 As described.

[0106] For example, the first UE 504a and the second UE 504b are vehicles communicating with each other, where such communication is referred to as vehicle-to-vehicle (V2V) communication. The third UE 504c can be a portable communication device, including, for example, a cellular phone, a laptop computer, or a wearable device. Sidelink communication between the first UE 504a and the third UE 504c can represent vehicle-to-pedestrian (V2P) communication. The fourth UE 504d can be a roadside unit (RSU), including, for example, traffic signs, traffic lights, lampposts, or any other wireless communication device deployed along or near a road or highway. Sidelink communication between the first UE 504a and the fourth UE 504d can represent vehicle-to-infrastructure (V2I) communication. As an RSU, the fourth UE 504d can collect and analyze traffic data generated by vehicles (e.g., the first UE 504a and the second UE 504b). The RSU can act as a gateway to other communication networks, for example, via a communication channel between the RSU and network entity 502. It should be noted that V2X communication can include other types of vehicle-to-network (V2N), vehicle-to-grid (V2G), vehicle-to-device (V2D), and vehicle-to-cloud (V2C). In some cases, UE 504 can communicate with each other via network entity 502, for example, via a Uu interface (e.g., a wireless communication channel between the radio access network (RAN) and the UE). Such communication can be referred to as various forms of X2N communication, such as V2N, pedestrian-to-network (P2N), and infrastructure-to-network (I2N).

[0107] The allocation of communication resources (e.g., time-frequency resources) for sidelink communication can be implemented in various modes. In Mode 1, network entity 502 can, for example, assign communication resources for sidelink communication via control signaling. For example, network entity 502 can assign communication resources to a first UE 504a to communicate with any of the other UEs 504b to 504d. In Mode 2, UE 504 autonomously selects, for example, resources from a resource pool for sidelink communication. UE 504 can communicate with each other autonomously without assistance from network entity 502. The autonomous V2X system 500 enables improved spectral efficiency, reduced costs, and increased reliability because no network service interruption occurs during handover operations for mobile vehicles.

[0108] In some cases, UE 504 can communicate with each other via licensed spectrum and / or unlicensed or shared spectrum. As previously discussed, unlicensed or shared spectrum can allow for increased radio channel capacity in V2X systems, especially to accommodate the rapid increase in vehicles supporting sidelink communication.

[0109] Example interleaved resource block for sidelink communication In some cases, frequency resources can be interleaved for certain wireless communications, including sidelink communications, and more specifically, sidelink communications in unlicensed or shared spectrum. The energy required for interleaved frequency resources to extend communication across channels in unlicensed or shared spectrum is required to meet various regulatory specifications, such as those of OCB, EIRP, and PSD, as discussed herein.

[0110] Figure 6 This is a diagram illustrating an example frequency resource interleaving scheme 600 across carriers. In this example, the carrier bandwidth 602 may be defined according to a contiguous resource block 610 (e.g., a PRB) in the frequency domain, where the carrier bandwidth 602 spans from the lowest frequency 620 of the carrier to the highest frequency 622 of the carrier relative to the lowest frequency 620. The lowest frequency 620 may be referred to as point A, which may be defined by an offset from a synchronization signal (or any other reference signal) or an absolute radio frequency channel number (ARFCN). In some cases, the carrier bandwidth 602 is in an unlicensed or shared radio band.

[0111] In some respects, carrier bandwidth 602 may be divided into various overlapping or non-overlapping portions (e.g., subbands), such as one or more bandwidth portions (BWPs) 604, one or more resource pools 606, and / or one or more resource block (RB) sets 608. A BWP is a set of contiguous resource blocks 610 on a given carrier. In some cases, one or more resource pools may be arranged in a BWP, and one or more RB sets may be arranged in a resource pool. Resource pool 606 includes a set of resource blocks in BWP 604, and RB set 608 includes a set of resource blocks in resource pool 606. In some cases, BWPs may be arranged in an overlapping or non-overlapping manner in carrier bandwidth 602. A BWP may overlap with another BWP or may not overlap, and the same applies to resource pools in a BWP and RB sets in a resource pool.

[0112] Multiple interleavings 612a to 612e (collectively referred to as interleaving 612) of resource block 610 are defined in carrier bandwidth 602 (and correspondingly in BWP 604, resource pool 606, and / or RB set 608), wherein the interleaving of resource blocks Including resource blocks ,in This is the total number of interleavings 612 arranged in the carrier bandwidth 602. A specific interleaving (e.g., the first interleaving 612a, where...) m =0 and M =5) The resource blocks 610 are spaced apart from each other by at least one other resource block 610 (e.g., the four resource blocks used for the first interleaving 612a). In some respects, M This depends on the SCS with a carrier bandwidth of 602. For example, for a 15kHz SCS,M It can be equal to 10, while for a 30kHz SCS, M It can be equal to 5.

[0113] For example, the first interleaving 612a of frequency resources 610 in resource pool 606 can be used for communication between one group of UEs, and the second interleaving 612b of resource pool 606 can be used for communication between another group of UEs. Thus, the different interleavings enable the two groups of UEs to extend the power of communication across unlicensed or shared channels and meet various regulatory requirements (e.g., OCB, EIRP, and PSD) discussed herein, while also using different frequency resources to mitigate interference.

[0114] Various aspects related to the configuration of interleaved frequency resources for sidelink feedback channels This disclosure provides techniques for configuring various frequency resource interleaving modes for PSFCH communication. In some aspects, the PSFCH configuration of interleaved frequency resources can be configured on a per-frequency-level basis, such as per BWP (e.g., as relative to...). Figure 7A and Figure 7B As described), by resource pool (e.g., relative to) Figures 8A to 8C (as described), or by RB set (e.g., as relative to) Figure 9A and Figure 9B (As described). In some respects, the PSFCH configuration of interleaved frequency resources can be configured implicitly, for example, as relative to... Figures 10A to 13B As described. In some cases, PSFCH configuration may be configured at the UE, for example, according to the standardization of the wireless communication system (e.g., at manufacturing time, via over-the-air updates, in firmware, etc.). In other cases, the UE may receive PSFCH configuration, for example, via control signaling including Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling, Downlink Control Information (DCI), Sidelink Control Information (SCI), and / or system information.

[0115] In some respects, a hybrid interleaving mode for PSFCH communication can define at least one common interleaving (in some cases, a single common interleaving) and one or more (e.g., also referred to as "K3") dedicated PRBs (e.g., arranged therein) that occupy a PRB for each PSFCH transmission (e.g., HARQ feedback transmission), which can be arranged on PRBs that are the same as each other but different from the common interleaving. The value of K3 can define the number of dedicated PRBs used in the hybrid interleaving mode. The value of K3 can be selected from a specific set of values, such as {1, 2, 5} for PSFCH communication with 15kHz and 30kHz SCS. In some cases, the interleaving index of the common interleaving for the hybrid interleaving mode can be configured per resource pool. The hybrid interleaving mode can be used, for example, to share a certain channel capacity on the common interleaving between UEs and promote spectral efficiency, while also providing some dedicated frequency resources for reliable PSFCH communication. Public interleaving can be shared among multiple UEs, and the K3 dedicated PRBs can be dedicated to UEs that send HARQ feedback on the K3 dedicated PRBs (and therefore also "dedicated" to UEs that receive HARQ feedback from UEs that send HARQ feedback on the K3 dedicated PRBs). For example, the K3 dedicated PRBs can be dedicated to a period of time such that other UEs near the UEs that send HARQ feedback on the K3 dedicated PRBs (and near the UEs that receive HARQ feedback on the K3 dedicated PRBs) do not send on the K3 dedicated PRBs.

[0116] In some respects, a dedicated interleaving mode for PSFCH communication can define at least one dedicated interleaving of a PRB or a portion thereof for PSFCH transmission (e.g., such that a PRB in at least one dedicated interleaving of a PRB or a portion thereof is similarly dedicated to a UE transmitting in at least one dedicated interleaving of a PRB and a UE receiving in at least one dedicated interleaving of a PRB, as discussed relative to K3 dedicated PRBs). The dedicated interleaving mode can be used for, for example, interference mitigation, load balancing, channel distribution, reliability improvement, etc.

[0117] For example, relative to Figure 6 The mixed interleaving mode can be configured for resource pool 606 (or RB set 608) of BWP 604, where common interleaving is assigned to the first interleaving 612a (e.g., m =0) and K3 PRBs in the fifth interlacing 612e (e.g., m =4). A dedicated interleaving mode can be configured for resource pool 606, where dedicated interleaving is assigned to the third interleaving 612c (e.g., m =2). In some respects, an interleaving assigned to a public or private interleaving can be identified by the interleaving index mapped to a specific resource block in the BWP and the interleaving associated with that resource block.

[0118] Example PSFCH configuration based on BWP interleaving frequency resources In some respects, PSFCH configuration for hybrid interleaving or dedicated interleaving modes can be applied at the BWP level. The PSFCH configuration may include, for example, an explicit indication via RRC signaling of using the hybrid interleaving mode for each resource pool in the BWP. In some cases, it may be expected that the UE is explicitly configured with a hybrid interleaving mode on at least one resource pool or on each resource pool in the BWP. For example, for each resource pool, the PSFCH configuration includes an explicit indication of the interleaving index used for common interleaving and the value of K3.

[0119] In some cases, if the interleaving index and / or K3 value used for common interleaving is not explicitly indicated in the PSFCH configuration, the default interleaving index and / or K3 value can be used in mixed interleaving mode.

[0120] The default interleaving index used for common interleaving can be set to any of a variety of indexes. For example, the default interleaving index used for common interleaving can be set to the lowest or highest interleaving index among any or all RB sets in the RB set within the resource pool. For example, multiple interleavings of PRBs can be arranged in each RB set within the RB set in the resource pool, and each interleaving in the RB set can have a different interleaving index. In some cases, the default interleaving index can be set to the interleaving index associated with the lowest PRB (in terms of frequency) in the resource pool. The default interleaving index can be set to the lowest or highest interleaving index among the interleaving indices associated with the RB set with the lowest or highest frequency in the resource pool. The lowest frequency RB set (or RB) can be the RB set (or RB) with the lowest frequency in the resource pool, and the highest frequency RB set (or RB) can be the RB set (or RB) with the highest frequency in the resource pool. In some cases, the default interleaving index can be set to the interleaving index associated with the lowest frequency RB in the lowest frequency RB set or the lowest frequency RB in the highest frequency RB set in the resource pool. The default interleaving index can be set to the interleaving index that is explicitly indicated in the configuration. This interleaving index is used to identify the interleaving index for common interleaving associated with the resource pool with the lowest or highest identifier in the resource pool that is explicitly configured with an interleaving index for common interleaving.

[0121] The default value for K3 can be set to any of a variety of values. The default value can be the minimum or maximum K3 value among multiple candidate values ​​(e.g., {1, 2, 5}). In some cases, the default value can be the K3 value associated with the resource pool that has the lowest or highest identifier among the resource pools configured with K3 values.

[0122] Figure 7AThis is a diagram depicting an example PSFCH configuration 700A, where a hybrid interleaving mode for PSFCH communication is configured for each resource pool 704a, 704b of BWP 702. In this example, PSFCH configuration 700A may include explicit indications of a common interleaving index and K3 value for each of the resource pools 704a, 704b for BWP 702. In some respects, each resource pool 704a, 704b may use the same or different common interleaving indices and / or the same or different K3 values ​​for the hybrid interleaving mode.

[0123] Figure 7B This is a diagram depicting an example PSFCH configuration 700B, in which at least one resource pool applies default values ​​for the default interleaving index and / or K3 for common interleaving. In this example, PSFCH configuration 700B may include explicit indications of the interleaving index and K3 values ​​for common interleaving of a first resource pool 704a. If PSFCH configuration 700B does not include explicit indications of the interleaving index and / or K3 values ​​for common interleaving of a second resource pool 704b, the UE may use default values ​​for the default interleaving index and / or K3 for common interleaving, for example, as described herein.

[0124] Example PSFCH configuration based on resource pool interleaving frequency In some respects, the PSFCH configuration for hybrid interleaving mode or dedicated interleaving mode can be applied at the resource pool level of the BWP. For example, in some respects, if the PSFCH configuration indicates that hybrid interleaving mode is used for at least one resource pool of the BWP, the PSFCH configuration implicitly indicates that hybrid interleaving mode is used for any other resource pool of the BWP. If the PSFCH configuration does not include explicit indications for any (and all) resource pools of the BWP to use hybrid interleaving mode, the PSFCH configuration implicitly indicates that dedicated interleaving mode is used for resource pools of the BWP. In some cases, if one resource pool of the BWP is explicitly configured for hybrid interleaving mode, the PSFCH configuration includes explicit indications for the interleaving index and K3 value for common interleaving for each resource pool in the resource pool. In some cases, resource pools of the BWP may be configured with shared (identical) K3 values. In some cases, resource pools of the BWP may be configured with different interleaving indices and / or different K3 values ​​for common interleaving. In some cases, if the PSFCH configuration does not include explicit indications for such values, the default interleaving index and / or default value of K3 for the resource pool can be used.

[0125] In some respects, the PSFCH configuration can indicate whether a resource pool for a BWP is assigned a hybrid interleaving mode or a dedicated interleaving mode. For example, different resource pools can be configured with different interleaving modes, such as hybrid interleaving or dedicated interleaving. In some respects, the PSFCH configuration can explicitly indicate whether each resource pool for a BWP is assigned a hybrid interleaving mode or a dedicated interleaving mode. In some respects, the PSFCH configuration can explicitly indicate that for each resource pool for a BWP that is assigned a hybrid interleaving mode, the hybrid interleaving mode should be used on such resource pools, and for any other resource pools for a BWP that are not explicitly indicated to use a hybrid interleaving mode, it implies that a dedicated interleaving mode should be used on these other resource pools.

[0126] Figure 8A This is a diagram depicting an example PSFCH configuration 800A, in which a first resource pool 804a of BWP 802 is configured to use a mixed interleaving mode. In such a case, where at least one resource pool 804a of BWP 802 is configured to use a mixed interleaving mode (e.g., via an indication of the interleaving index and / or K3 value for common interleaving of the first resource pool 804a), it is expected that PSFCH configuration 800A (or it may implicitly) indicates that the mixed interleaving mode is used for a second resource pool 804b of BWP 802 (e.g., via an indication of the interleaving index and / or K3 value for common interleaving of the second resource pool 804b).

[0127] Figure 8B This is a diagram depicting an example PSFCH configuration 800B, where the default interleaving index and / or default value of K3 used for common interleaving are applied to the hybrid interleaving mode of the second resource pool 804b. In this example, for instance, since the first resource pool 804a is explicitly configured to use the hybrid interleaving mode within the same BWP 802, and further since the second resource pool 804b is not explicitly configured with values ​​for the interleaving index and K3, the PSFCH configuration 800B implicitly indicates that the default configuration will be used for the hybrid interleaving mode of the second resource pool 804b.

[0128] Figure 8C This is a diagram depicting an example PSFCH configuration 800C, where each of the resource pools 804a and 804b of BWP 802 is individually configured for either a hybrid interleaving mode or a dedicated interleaving mode. In this example, PSFCH configuration 800C indicates that a hybrid interleaving mode is used for the first resource pool 804a, and a dedicated interleaving mode is used for the second resource pool 804b. Such a PSFCH configuration scheme allows for dynamic allocation of interleaving frequencies according to resource pools, for example, to promote efficient signaling overhead, interference mitigation, load balancing, channel distribution, HARQ feedback reliability improvements, etc., depending on the interleaving mode selected for PSFCH communication.

[0129] Example PSFCH configuration of interleaved frequency resources by RB set In some respects, the PSFCH configuration for mixed interleaving or dedicated interleaving modes can be applied at the RB set level. For example, in some respects, the PSFCH can indicate whether a resource pool's RB set is assigned to mixed interleaving or dedicated interleaving mode. In some cases, the PSFCH configuration may include an explicit indication of using mixed interleaving mode for any RB set assigned to a resource pool using mixed interleaving mode. If the PSFCH configuration does not include an explicit indication of using mixed interleaving mode for any other RB set of the resource pool, the PSFCH configuration implicitly indicates that dedicated interleaving mode is used for other RB sets of the resource pool. In some cases, the RB sets of a resource pool may be configured with shared K3 values. The RB sets of a resource pool may be configured with different interleaving indices and / or different K3 values ​​for common interleaving. In some cases, if the PSFCH configuration does not include an explicit indication of such values, the default interleaving index and / or default value of K3 for the RB set can be used.

[0130] Figure 9A This is a diagram depicting an example PSFCH configuration 900A, where interleaving indexes and / or K3 values ​​are assigned per resource pool for common interleaving. In this example, PSFCH configuration 900A indicates interleaving indexes and / or K3 values ​​for a first resource pool 904a and a second resource pool 904b for BWP 902. These values ​​may be different or the same. PSFCH configuration 900A indicates that a mixed interleaving mode is used for a first RB set 906a of the first resource pool 904a, and a dedicated interleaving mode is used for a second RB set 906b of the first resource pool 904a. PSFCH configuration 900A also indicates that a mixed interleaving mode is used for RB sets 908a and 908b of the second resource pool 904b. The first RB set 906a is assigned the interleaving indexes and / or K3 values ​​indicated for the first resource pool 904a, and the RB sets 908a and 908b are assigned the interleaving indexes and / or K3 values ​​indicated for the second resource pool 904b.

[0131] Figure 9B This is a diagram depicting example PSFCH configuration 900B, where the value of K3 is assigned per RB set. In this example, each of the RB sets 906a, 908a, and 908b configured for mixed interleaving mode is assigned a separate value of K3, while the interleaving indexes for common interleaving of RB sets 906a, 908a, and 908b are assigned per resource pool, as described herein relative to... Figure 9A As described. For each of the RB sets 906a, 908a, and 908b, the PSFCH configuration 900B may include an explicit indication of the value of K3. Note that the interleaving index used for common interleaving can be identified by the RB set.

[0132] Example implicit configuration of interleaved frequency resources for PSFCH communication In some respects, hybrid interleaving mode or dedicated interleaving mode can be implicitly configured. In some cases, whether hybrid or dedicated interleaving mode is used for PSFCH communication on a BWP or any part thereof (e.g., a resource pool or RB set) may depend on whether an interleaving index for common interleaving is configured. For example, a PSFCH configuration indicating the interleaving index for common interleaving associated with a resource pool (or RB set) of the BWP may implicitly indicate that hybrid interleaving mode is used for that resource pool (or RB set). Otherwise, the PSFCH configuration indicates that dedicated interleaving mode is used on that resource pool (or RB set). In such cases where the interleaving index for common interleaving is configured for a resource pool (or RB set) and implicitly indicates that hybrid interleaving mode is used for the resource pool (or RB set), the PSFCH configuration is expected to also indicate a value for K3 for the resource pool (or RB set). In some cases, if the PSFCH configuration does not explicitly indicate a value for K3, the default value for K3 may be used.

[0133] In some respects, whether to use a hybrid interleaving mode or a dedicated interleaving mode for PSFCH communication on a BWP or any part thereof (e.g., a resource pool or RB set) may depend on whether a K3 value is configured. For example, a PSFCH configuration indicating the K3 value associated with a resource pool (or RB set) of the BWP may implicitly indicate that a hybrid interleaving mode is used for that resource pool (or RB set). Otherwise, the PSFCH configuration indicates that a dedicated interleaving mode is used on that resource pool (or RB set). It is expected that the PSFCH configuration may also indicate an interleaving index associated with the resource pool (or RB set) for common interleaving. In some cases, if the PSFCH configuration does not explicitly indicate an interleaving index, a default interleaving index for common interleaving may be used.

[0134] Figure 10A This is a diagram depicting an example PSFCH configuration 1000A, where the indication of the interleaving index for common interleaving implicitly indicates that a mixed interleaving mode is used for the resource pool. In this example, the first resource pool 1004a of BWP 1002 is configured with an interleaving index for common interleaving, and therefore, PSFCH configuration 1000A implicitly indicates that a mixed interleaving mode is used for the first resource pool 1004a. PSFCH configuration 1000A does not include an indication of an interleaving index for common interleaving associated with the second resource pool 1004b, and therefore, PSFCH configuration 1000A implicitly indicates that a dedicated interleaving mode is used for the second resource pool 1004b.

[0135] Figure 10BThis is a diagram depicting example PSFCH configuration 1000B, where the indication of the interleaving index used for common interleaving implicitly indicates the use of a mixed interleaving mode, but uses the default value for K3. In this example, PSFCH configuration 1000B does not include an explicit indication of the K3 value associated with the second resource pool 1004b, and therefore, uses the default value for K3.

[0136] Figure 11A This is a diagram depicting an example PSFCH configuration 1100A, where the indication of the value of K3 implicitly indicates the use of a hybrid interleaving mode on the resource pool. In this example, the first resource pool 1104a of BWP 1102 is configured with the value of K3, and therefore, PSFCH configuration 1100A implicitly indicates that a hybrid interleaving mode is used for the first resource pool 1104a. PSFCH configuration 1100A does not include an indication of the value of K3 associated with the second resource pool 1104b, and therefore, PSFCH configuration 1100A implicitly indicates that a dedicated interleaving mode is used for the second resource pool 1104b.

[0137] Figure 11B This is a diagram depicting example PSFCH configuration 1100B, where the indication of the value of K3 implicitly indicates the use of a hybrid interleaving mode, but uses the default interleaving index. PSFCH configuration 1100B does not include an explicit indication of the interleaving index associated with the second resource pool 1104b for common interleaving, and therefore, uses the default interleaving index for common interleaving.

[0138] In some respects, a specific value for K3 (e.g., a specific code point) can implicitly indicate the use of a dedicated interleaving mode on the BWP or a portion thereof (e.g., a resource pool or RB set). For example, a K3 value of "10 PRBs" can indicate the use of a dedicated interleaving mode, regardless of whether an interleaving index is configured for public interleaving. In some cases where a specific value for K3 is indicated on a resource pool or RB set, the UE can use all or some of the PRBs in the dedicated interleaving (e.g., 10 or 11), depending on the number of PRBs in the dedicated interleaving. In some cases where a specific value for K3 is indicated on a resource pool or RB set, the UE can use the indicated K3 value for dedicated interleaving, regardless of whether more PRBs are included in the dedicated interleaving. For example, if 11 PRBs are included in the dedicated interleaving, the UE can use either the first 10 or the last 10 PRBs in the dedicated interleaving. In some cases, where a specific value for K3 is indicated, and an interleaving index for public interleaving is also indicated, the PSFCH configuration can continue to implicitly indicate the use of a dedicated interleaving mode, regardless of whether an interleaving index for public interleaving exists.

[0139] In some cases, if the value of K3 is set to a candidate value other than the special value used for a resource pool or RB set (e.g., 10) (e.g., {1, 2, 5}), the PSFCH configuration implicitly indicates the use of a mixed interleaving mode on the corresponding resource pool or RB set. If no interleaving index is configured for a resource pool or RB set, the default interleaving index used for common interleaving is used.

[0140] Figure 12A This is a diagram depicting an example PSFCH configuration 1200A, where a special value for K3 (e.g., K3 = 10) indicates that a dedicated interleaving mode is used for the resource pool. In this example, the second resource pool 1204b of BWP 1202 is assigned the special value of K3, and therefore, based on the special value of K3, PSFCH 1200A implicitly indicates that a dedicated interleaving mode is used for the second resource pool 1204b, regardless of whether an interleaving index for common interleaving is also assigned to the second resource pool 1204b.

[0141] Figure 12B This is a diagram depicting an example PSFCH configuration 1200B, where each of resource pools 1204a and 1204b is configured with candidate values ​​for K3, such as 2 and 5. Therefore, based on the candidate values ​​assigned to each of resource pools 1204a and 1204b, PSFCH 1200B implicitly indicates that a mixed interleaving mode should be used for resource pools 1204a and 1204b.

[0142] Figure 13A This is a diagram depicting an example PSFCH configuration 1300A, where RB sets are implicitly configured for either mixed interleaving or dedicated interleaving modes, depending on whether a K3 value is configured for the respective RB set. In this example, RB sets 1306a, 1308a, and 1308b are configured with a K3 value, and in this case, PSFCH configuration 1300A implicitly indicates that mixed interleaving mode is used for RB sets 1306a, 1308a, and 1308b. The PSFCH configuration does not include an explicit indication of the K3 value associated with RB set 1306b of resource pool 1304a, and in this case, the PSFCH configuration implicitly indicates that dedicated interleaving mode is used for RB set 1306b of resource pool 1304a, regardless of whether an interleaving index for common interleaving is also assigned to resource pool 1304a.

[0143] Figure 13BThis is a diagram depicting an example PSFCH configuration 1300B, where a specific value for K3 (e.g., K3 = 10) indicates that a dedicated interleaving mode is used for the RB set. In this example, the RB set 1306b of resource pool 1304a is assigned the specific value of K3, and therefore, based on the specific value of K3, PSFCH 1300A implicitly indicates that a dedicated interleaving mode is used for RB set 1306b, regardless of whether an interleaving index for common interleaving is also assigned to resource pool 1304a. RB sets 1306a, 1308a, and 1308b are configured with candidate values ​​for K3, and in such cases, PSFCH configuration 1300A implicitly indicates that a mixed interleaving mode is used for RB sets 1306a, 1308a, and 1308b.

[0144] Example operations of entities in a communication network Figure 14 A process flow 1400 is described for communication within a network (including UEs 1404a and 1404b (collectively referred to as UE 1404) and in some cases, network entity 1402). In some aspects, network entity 1402 may be relative to... Figure 1 and Figure 3 The BS 102 depicted and described, or relative to Figure 2 Examples of decomposed base stations depicted and described. Similarly, UE 1404 can be relative to... Figure 1 and Figure 3 Examples of UE 104 depicted and described herein. However, in other respects, UE 1404 may be another type of wireless communication device, and network entity 1402 may be another type of network entity or network node, such as those described herein. In some respects, UE 1404 may communicate with each other via sidelink communication, for example, in unlicensed or shared spectrum. In some cases, UE 1404 may participate in any V2X communication of various V2X communications, such as V2V, V2I, and / or V2P, for example, as described herein with respect to... Figure 5 As described.

[0145] At 1406, UE 1404 may receive PSFCH configuration from network entity 1402, which indicates one or more frequency interleaving modes (e.g., hybrid interleaving mode or dedicated interleaving mode) for PSFCH communication, for example, as described herein with respect to Figures 7A to 13BAs described. For example, the PSFCH configuration may include an explicit indication of using a hybrid interleaving mode for a specific resource pool, having indications of the interleaving index and the value of K3 for common interleaving. In some aspects, the PSFCH configuration may be received via control signaling such as RRC signaling, MAC signaling, DCI and / or system information. In some aspects, network entity 1402 may configure UE 1404 for sidelink configuration under a specific sidelink communication mode (e.g., mode 1).

[0146] At 1408, the first UE 1404a can receive PSFCH configuration from the second UE 1404b, which indicates one or more frequency interleaving modes for PSFCH communication, for example, as described herein with respect to... Figures 7A to 13B As described, and / or vice versa, a second UE 1404b may receive PSFCH configuration from a first UE 1404a. In some aspects, the PSFCH configuration may be received via control signaling such as RRC signaling, MAC signaling, SCI and / or system information. In some aspects, UEs 1404 may autonomously configure sidelink configurations to each other under a specific sidelink communication mode (e.g., mode 2). In some cases, only one of 1406 or 1408 occurs to communicate the PSFCH configuration to one or more UEs. In some cases, both 1406 and 1408 occur to communicate the PSFCH configuration to one or more UEs. In such cases, the UE may select which PSFCH configuration received at 1406 and 1408 is used for PSFCH communication based on certain criteria, such as the priority associated with the PSFCH configuration.

[0147] At 1410, the first UE 1404a receives information from the second UE 1404b, for example, via PSSCH. For example, the second UE 1404b may send certain security warnings and / or traffic information related to V2V communication to the first UE 1404a.

[0148] At 1412, in response to the received information, the first UE 1404a sends HARQ feedback (e.g., ACK or NACK) to the second UE 1404b using a frequency interleaving mode, based on the PSFCH configuration received at 1406 and / or 1408. For example, the first UE 1404a uses a hybrid interleaving mode in common interleaving and K3 dedicated PRBs to send the HARQ feedback. The second UE 1404b uses a hybrid interleaving mode in common interleaving and K3 dedicated PRBs to monitor HARQ feedback in the PSFCH. The hybrid interleaving mode extends the energy of HARQ feedback transmission across channels to meet various regulatory specifications, such as those of OCB, EIRP, and PSD, as discussed herein. Hybrid interleaving mode can be used, for example, to share a channel capacity on a common interleaving between UEs (e.g., UE 1404) and promote spectral efficiency, while also providing some dedicated frequency resources for reliable PSFCH communication (e.g., ACK or NACK), such as for HARQ feedback from the first UE 1404a to the second UE 1404b.

[0149] At 1414, in response to HARQ feedback (e.g., NACK), the first UE 1404a can receive retransmissions of information. The K3 dedicated PRBs in the hybrid interleaving mode facilitate reliable HARQ feedback from the first UE 1404a to the second UE 1404b.

[0150] Example Operation Figure 15 It shows a device (such as) Figure 1 and Figure 3 Method 1500 for wireless communication with UE 104. In some cases, the device may communicate with the UE via sidelink communication, for example, in unlicensed or shared spectrum. In some cases, the device may participate in any V2X communication of various V2X communications, such as V2V, V2I and / or V2P, for example, as described herein with respect to Figure 5 As described.

[0151] Method 1500 begins at box 1505: A configuration is obtained indicating that, for each of one or more portions (e.g., resource pools or RB sets) of a carrier bandwidth BWP, the following items are used for PSFCH communication on the corresponding portion: 1) a corresponding common interleaved resource block shared by multiple devices in the corresponding portion and a corresponding set of dedicated resource blocks in the corresponding portion dedicated to that device, or 2) a corresponding dedicated interleaved resource block in the corresponding portion dedicated to that device, wherein the one or more portions include a first portion, and wherein the configuration indicates that a first common interleaved resource block of the first portion and a first set of dedicated resource blocks of the first portion are used for PSFCH communication on the first portion. For example, the configuration may include any PSFCH configuration indicating the use of a hybrid interleaving mode or a dedicated interleaving mode as described herein, such as... Figures 7A to 13B The PSFCH configuration is described.

[0152] Method 1500 then proceeds to block 1510: conveying information on the sidelink channel, for example, as described herein relative to... Figure 14 As described.

[0153] Method 1500 then proceeds to box 1515: for example, using a hybrid interleaving mode as described herein to convey feedback associated with the information (e.g., HARQ feedback) in the first PSFCH communication within the first common interleaving resource block of the first part and the first set of dedicated resource blocks of the first part.

[0154] In some respects, the first set of dedicated resource blocks in the first part is arranged in the first interleaved resource blocks of the first part, which are different from the first common interleaved resource blocks.

[0155] In some respects, this configuration is obtained via RRC signaling.

[0156] In some respects, the configuration includes a BWP-level configuration for the BWP; the one or more portions include one or more of the following: (1) one or more resource pools, or (2) one or more RB sets of the one or more resource pools; and the BWP-level configuration includes an explicit indication for each of the one or more portions of the BWP that the corresponding common interleaved resource blocks of the corresponding portion and the corresponding set of dedicated resource blocks of the corresponding portion are used for PSFCH communication on the corresponding portion.

[0157] In some respects, the configuration includes a BWP-level configuration for the BWP; the one or more portions include one or more of the following: (1) one or more resource pools, or (2) one or more RB sets of the one or more resource pools; and the BWP-level configuration indicates, for each of the one or more portions of the BWP, that the corresponding dedicated interleaved resource blocks of the corresponding portion of the one or more portions be used for PSFCH communication on the corresponding portion based on one of the following: the BWP-level configuration does not include an explicit indication for each of the one or more portions of the BWP that the corresponding common interleaved resource blocks of the corresponding portion and the corresponding set of dedicated resource blocks of the corresponding portion be used for PSFCH communication on the corresponding portion, or the BWP-level configuration includes an explicit indication for each of the one or more portions of the BWP that the corresponding dedicated interleaved resource blocks of the corresponding portion of the one or more portions be used for PSFCH communication on the corresponding portion.

[0252] As used in this article, the phrase “at least one of” in a list of entries refers to any combination of those entries, including a single member. As an example, “at least one of A, b, or c” is intended to cover: a, b, c, ab, ac, bc, and abc, as well as any combination with multiple identical elements (e.g., aa, aaa, aab, aac, abb, acc, bb, bbb, bbc, cc, and ccc, or any other ordering of a, b, and c).

[0253] As used herein, the term "determine" encompasses a wide variety of actions. For example, "determine" can include calculation, operation, processing, deduction, investigation, lookup (e.g., searching in a table, database, or other data structure), assertion, etc. Additionally, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data in memory), etc. Furthermore, "determine" can include parsing, selecting, picking, building, etc.

[0254] As used herein, unless otherwise stated, “coupled to” and “coupled with” generally encompass both direct and indirect coupling (e.g., including intermediate aspects of coupling).

The terms “set” and “group” are intended to include one or more elements and are used interchangeably with “one or more”. In the case of references to one or more elements performing a function (e.g., steps of a method), one element may perform all the functions, or more than one element may collectively perform those functions. When more than one element performs these functions together, each function does not need to be performed by every single element (e.g., different functions can be performed by different elements), and / or each function does not need to be performed by only one element as a whole (e.g., different elements can perform different sub-functions of a function). Similarly, when referring to one or more elements configured to cause another element (e.g., a device) to perform a function, one element may be configured to cause another element to perform all functions, or more than one element may be jointly configured to cause another element to perform these functions. Unless otherwise specifically stated, the term "some" refers to one or more. All structural and functional equivalents of the various aspects described throughout this disclosure that are currently or hereafter known to those skilled in the art are intended to be covered by the claims.
