[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 979,861, filed on February 21, 2020, entitled “TECHNIQUES FOR SHARING SIDELINK RESOURCE,” and U.S. Non-Provisional Patent Application No. 17 / 171,394, filed on February 9, 2021, entitled “TECHNIQUES FOR SHARING SIDELINK RESOURCE,” which are expressly incorporated herein by reference. Technical Field

[0003] Aspects of the disclosure relate generally to wireless communications, and to techniques and apparatus for sharing sidelink resources. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of these multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) that can support communication for multiple user equipment (UEs). UEs can communicate with a BS via downlinks and uplinks. A downlink (or forward link) refers to the communication link from a BS to a UE, and an uplink (or reverse link) refers to the communication link from a UE to a BS. As described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmission reception point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at a municipal, national, regional, and even global level. NR (also known as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and better integrating with other open standards that use orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and support beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0063] Various aspects of the present invention are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure detailed and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should understand that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of any other aspect of the disclosure or combined with any other aspect of the disclosure. For example, any number of aspects set forth herein can be used to implement an apparatus or practice method. In addition, the scope of the present disclosure is intended to cover such apparatus or method that utilizes other structures, functions, or structures and functions practiced in addition to the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of the claims.

[0064] Several aspects of telecommunications systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0065] It should be noted that although various aspects may be described herein using techniques generally associated with 5G or NR radio access technology (RAT), various aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or RATs beyond 5G (e.g., 6G).

[0066] Figure 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 may include a plurality of base stations 110 (illustrated as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving that coverage area, depending on the context in which the term is used.

[0067] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs through service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs through service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BS 110a may be a macro BS for macrocell 102a, BS 110b may be a pico BS for picocell 102b, and BS 110c may be a femto BS 102c for a femtocell. A BS may support one or more (e.g., three) cells. The terms "eNB," "base station," "NR BS," "gNB," "TRP," "AP," "Node B," "5G NB," and "cell" may be used interchangeably herein.

[0068] In some aspects, the cells may not necessarily be fixed, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks using any suitable transport network.

[0069] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, etc.

[0070] The wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0071] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other (eg, directly or indirectly via a wireless backhaul or a wired backhaul).

[0072] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart wristband)), an entertainment device (e.g., a music or video device or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless medium or a wired medium.

[0073] Some UEs may be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or to a network via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component and / or a memory component). In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0074] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RATs can also be referred to as radio technologies, air interfaces, etc. Frequencies can also be referred to as carriers, frequency channels, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0075] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communicating with each other). For example, UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0076] Devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1), which can be from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2), which can be from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) recognized as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise expressly stated, it should be understood that the term "sub-6 GHz," etc., if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Therefore, unless otherwise expressly stated, it should be understood that the term "millimeter wave," etc., if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0077] As pointed out above, Figure 1 are provided as examples. Other examples may be related to Figure 1 Different than described.

[0078] Figure 2is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0079] At the base station 110, a transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0080] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may also process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) reference, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, among other examples. In some aspects, one or more components of UE 120 may be included in a housing.

[0081] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0082] The antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include, or may be included in, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, among other examples. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include a collection of coplanar antenna elements and / or a collection of non-coplanar antenna elements. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmit and / or receive components, such as Figure 2 One or more components of a .

[0083] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 (if applicable), further processed by the modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0084] At base station 110, uplink signals from UE 120 and other UEs may be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include a communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include a scheduler to schedule UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in a modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0085] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the base station 110 may perform one or more techniques associated with sidelink resource sharing, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 4 4 and / or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communications. For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, conversion, and / or interpretation), the one or more instructions may cause the one or more processors, UE 120, and / or base station 110 to perform or direct (e.g., Figure 4

[0066] The operations of process 400 and / or other processes as described herein may include executing instructions, converting instructions, compiling instructions, and / or interpreting instructions.

[0086] In some aspects, UE 120 may include means for receiving resource information associated with a plurality of provider UEs from the plurality of provider UEs; means for selecting one or more resources associated with one or more selected ones of the plurality of provider UEs based at least in part on a sorted order and the resource information, wherein the sorted order is based at least in part on measurement information associated with the plurality of provider UEs determined by a receiving UE; means for performing sidelink communication using the one or more resources; means for selecting the one or more selected UEs based at least in part on the sorted order; means for determining an average of the provider UEs in the plurality of provider UEs using the measurement information, wherein the sorted order and the selection of the one or more selected UEs are based at least in part on the average; means for determining the sorted order based at least in part on the measurement information, and the like. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and so forth.

[0087] As pointed out above, Figure 2 are provided as examples. Other examples may be related to Figure 2 Different than described.

[0088] The wireless communication system may include or provide support for various types of communication systems, such as vehicle-related communication systems (e.g., vehicle-to-everything (V2X) communication systems). Vehicle-related communication systems may be used by vehicles to increase safety and help prevent vehicle collisions. Information about severe weather, nearby accidents, road conditions, and / or other information may be transmitted to the driver via the vehicle-related communication system. In some cases, vehicles may communicate directly with each other using sidelink communications (e.g., device-to-device (D2D) communications via D2D wireless links).

[0089] In order to improve the reliability of sidelink transmission, UEs can coordinate with each other to share resource information. That is, a first UE (referred to herein as a provider UE) can identify communication resources by sensing the surrounding environment of the first UE. The communication resources identified by the first UE can be identified by resource information (such as resource mapping). These communication resources can also be referred to as sensing information. The first UE can send resource information (e.g., the identified communication resources) to a second UE (referred to herein as a recipient UE). The recipient UE can consider the resource information when selecting resources for sidelink transmission.

[0090] However, resource information from one provider UE may be more useful to a recipient UE than resource information from another provider UE. For example, if the provider UE is in a substantially different environment than the recipient UE (e.g., due to the distance between the provider UE and the recipient UE, different obstructions or environments associated with the provider UE and the recipient UE, etc.), the resource information provided by the provider UE may be suboptimal or even detrimental to the performance of the recipient UE. Irrelevant or non-useful resource information may be particularly problematic for recipient UEs that do not perform their own sensing operations, such as low-power UEs, battery-constrained UEs, UEs associated with heavy duty cycles, etc.

[0091] Some techniques and apparatus described herein provide resource selection based at least in part on measurements associated with a provider UE from which corresponding resource information is received. For example, a receiving UE may determine measurements (e.g., RSRP measurements, etc.) of a provider UE from which resource information is received. The receiving UE may select a selected provider UE (e.g., a top provider UE) or a set of selected provider UEs (e.g., a top set of provider UEs) based at least in part on the measurements. For example, the receiving UE may select the top set of provider UEs associated with the strongest RSRP measurements. The receiving UE may select one or more resources from the resource information associated with the top set of provider UEs. Thus, the receiving UE may identify resources associated with a provider UE located close to the UE, which increases the likelihood that the resource information of the selected provider UE is accurate and / or useful to the receiving UE. Thus, the communication performance of the receiving UE is improved, thereby saving computing resources of the receiving UE that would otherwise be used in association with inaccurate or irrelevant resource mappings.

[0092] Figure 3 3 is a diagram illustrating an example 300 of side link resource sharing according to the present disclosure. As shown in the figure, Figure 3 The embodiment includes a set of receiver UEs 305 and provider UEs 310-1, 310-2, and 310-3. The receiver UE 305 may be UE 120. In some aspects, the receiver UE 305 may be a low power UE, an IoT UE, a UE with reduced capabilities, etc. In some aspects, the receiver UE 305 may perform the combined operation based at least in part on the fact that the receiver UE 305 is a low power UE, an IoT UE, a UE with reduced capabilities, etc. Figure 3 In some aspects, the receiving UE 305 may perform the combined operation based at least in part on the receiving UE 305 being configured or determined not to perform sensing operations to determine resource mapping. Figure 3 Describes the operation.

[0093] Provider UE 310 may be UE 120. As shown, different provider UEs 310 may be at different distances from recipient UE 305. For example, provider UE 310-3 may be closer than provider UE 310-1 or provider UE 310-2. Recipient UE 305 and provider UE 310 may be part of a sidelink resource sharing system, meaning that recipient UE 305 and provider UE 310 may share resources for sidelink transmissions between recipient UE 305 and provider UE 310 and / or to or from other devices.

[0094] like Figure 3As shown, provider UEs 310-1 to 310-3 may provide control information to recipient UE 305. As further shown, the control information may include resource information determined by the corresponding provider UE 310. For example, Figure 3 Each of the multiple provider UEs 310 shown can determine respective resource information. The resource information can include resource mapping, sensing information, etc. For example, the resource information can identify available resources for sidelink communications performed by the corresponding provider UE 310. The control information can include, for example, a physical sidelink shared channel (PSSCH), sidelink control information (SCI), etc. In some aspects, the control information can be provided on a sidelink interface between the UEs 305 / 310, such as a ProSe sidelink (PC5) interface.

[0095] As shown by reference numeral 315, the recipient UE 305 can determine a measurement of the provider UE (e.g., a measurement value such as RSRP) based at least in part on the received resource information. For example, the recipient UE 305 can determine the measurement based at least in part on the control information. Here, the measurement includes an RSRP value, although the measurement can be any form of measurement that can be determined by the recipient UE 305. As shown, the control information received from the provider UE 310-3 is associated with the strongest RSRP value (e.g., -50 decibel-milliwatts (dBm)), followed by the control information from the provider UE 310-2, and then the control information from the provider UE 310-1.

[0096] In some aspects, the recipient UE 305 determines measurements over time. For example, the recipient UE 305 can store measurement information related to the provider UE 310. In some aspects, the recipient UE 305 can determine combined measurements of the provider UE 310, such as an average measurement within a time window (e.g., a time average), the highest measurement in the time window, the lowest measurement in the time window, the median measurement in the time window, the deviation or variance of measurements in the time window, etc. The recipient UE 305 can use such combined measurements to determine the ranking and / or grouping of the provider UEs 310. By determining the aggregated measurements, fading can be averaged and link budget data for RSRP can be determined, which can be useful for network configuration and scheduling purposes.

[0097] As indicated by reference numeral 320, the recipient UE 305 may determine a ranked order of the provider UEs 310 based at least in part on measurements (e.g., RSRP). For example, the recipient UE 305 may assign the highest ranking to the provider UE 310-3, the middle ranking to the provider UE 310-2, and the lowest ranking to the provider UE 310-1 based on the respective RSRP values ​​of the provider UEs 310. In some aspects, the recipient UE 305 may divide the plurality of provider UEs 310 into two or more sets based at least in part on the measurements, such as a first set that satisfies a threshold (indicating that resource information of the first set can be used by the recipient UE 305) and a second set that fails to satisfy the threshold (indicating that resource information of the second set cannot be used by the recipient UE 305).

[0098] As shown by reference numeral 325, the recipient UE 305 can select one or more UEs according to the sorted order. For example, the recipient UE 305 can select the highest-ranked provider UE 310, the highest-ranked N provider UEs 310 (where N is an integer greater than or equal to 1), all provider UEs 310 of the first set, and the like. The recipient UE 305 can use the resource information associated with the one or more selected UEs to select resources for sidelink communication. For example, compared to a lower-ranked UE 310, the one or more selected UEs may be closer to the recipient UE 305 or associated with a more direct channel to the recipient UE 305, which therefore means that compared to the resource information associated with the lower-ranked UE 310, the resource information associated with the one or more selected UEs may be more accurate and / or more useful to the recipient UE 305.

[0099] As shown by reference numeral 330, the receiving UE 305 may select one or more resources from the resource information of one or more selected UEs. For example, the receiving UE 305 may select resources for sidelink communication. In some aspects, the sidelink communication may be between the receiving UE 305 and a UE from which the resource information identifying the selected resources is received. In some aspects, the sidelink communication may be between the receiving UE 305 and another device (e.g., another UE, a roadside unit, a base station, etc.). In some aspects, the sidelink communication may be a broadcast communication from the receiving UE 305. As shown by reference numeral 335, the receiving UE 305 may perform sidelink communication using the one or more selected resources.

[0100] In some aspects, the recipient UE 305 may select resources based at least in part on the combined resource information. For example, the recipient UE 305 may combine the resource information of two or more provider UEs 310 (e.g., the two or more provider UEs 310 with the highest ranking, two or more provider UEs 310 of the first set, etc.). In some aspects, the recipient UE 305 may combine the resource information based at least in part on the resource information of a pair of provider UEs 310 that can be coherently combined. As used herein, "coherently combineable" may refer to resource information using the same format, the same ranking or numbering system, etc., so that the resource information can be combined using a join operation, an addition operation, etc. Therefore, the recipient UE 305 can use the combined resource information to select resources, which can provide more accurate and complete resource information about the channel around the recipient UE 305, thereby improving the accuracy of resource selection.

[0101] As pointed out above, Figure 3 are provided as examples. Other examples may be related to Figure 3 Different than described.

[0102] Figure 4 is a diagram illustrating an example process 400 performed by, for example, a UE in accordance with the present disclosure. Example process 400 is an example in which a receiving UE (eg, UE 120, receiving UE 305, etc.) performs operations associated with sidelink resource sharing.

[0103] like Figure 4 As shown, in some aspects, process 400 may include receiving resource information associated with multiple provider UEs from multiple provider UEs (block 410). For example, a receiving UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive resource information associated with multiple provider UEs from multiple provider UEs (e.g., UE 120, provider UE 310, etc.), as described above. In some aspects, the techniques described herein may be applied to resource information received from a single provider UE (e.g., the receiving UE may determine whether measurements associated with the single provider UE meet a threshold and may selectively use the resource information of the single provider UE, or accordingly determine not to use the resource information of the single provider UE).

[0104] like Figure 4As further shown in FIG, in some aspects, process 400 may include selecting one or more resources associated with one or more selected ones of the plurality of provider UEs based at least in part on a sorted order and the resource information, wherein the sorted order is based at least in part on measurement information associated with the plurality of provider UEs determined by the recipient UE (block 420). For example, the recipient UE (e.g., using the controller / processor 280, etc.) may select one or more resources associated with the one or more selected ones of the plurality of provider UEs based at least in part on the sorted order and the resource information, as described above. In some aspects, the sorted order is based at least in part on measurement information associated with the plurality of provider UEs determined by the recipient UE.

[0105] like Figure 4 As further shown in FIG4 , in some aspects, process 400 may include performing sidelink communications using one or more resources (block 430). For example, a receiving UE (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) may perform sidelink communications using one or more resources, as described above.

[0106] Process 400 may include additional aspects, such as any single aspect and / or any combination of aspects described below or in combination with one or more other processes described elsewhere herein.

[0110] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the one or more selected UEs include a highest ranked set of UEs according to the sorted order.

[0112] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, the measurement information identifies respective reference signal received power (RSRP) values ​​of the plurality of provider UEs.

[0113] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, process 400 includes determining an average of provider UEs among a plurality of provider UEs using measurement information, wherein a sorted order and selection of one or more selected UEs are based at least in part on the average.

[0114] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, the one or more selected UEs are selected based at least in part on measurement information associated with the one or more selected UEs satisfying a threshold.

[0115] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, process 400 includes determining a sorted order based at least in part on measurement information.

[0116] In a tenth aspect, alone or in combination with one or more of the first to ninth aspects, process 400 includes determining measurement information.

[0117] In an eleventh aspect, alone or in combination with one or more of the first to tenth aspects, the resource information is received in a control signal.

[0118] although Figure 4 Example blocks of process 400 are shown, but in some aspects, process 400 may include more Figure 4 More blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in process 400 may be used. Additionally or alternatively, two or more of the blocks of process 400 may be executed in parallel.

[0119] Figure 5 5 is a data flow diagram 500 illustrating the flow of data between different components in an example apparatus 502 according to the present disclosure. Apparatus 502 can be a UE (e.g., UE 120, UE 305). In some aspects, apparatus 502 includes a receiving component 504, a selecting component 506, a performance component 508, a determining component 510, and / or a transmitting component 512.

[0120] Receiving component 504 can receive resource information associated with a plurality of provider UEs 550 (e.g., UE 120 or UE 310). Determining component 510 can determine measurement information based at least in part on the resource information (e.g., based at least in part on control information used to provide the resource information). In some aspects, determining component 510 can determine a sorted order based at least in part on the measurement information. In some aspects, determining component 510 can use the measurement information to determine an average of the provider UEs in the plurality of provider UEs 550, wherein the sorted order and the selection of one or more selected UEs are based at least in part on the average. Selecting component 506 can select one or more resources associated with one or more selected UEs in the plurality of provider UEs 550 based at least in part on the sorted order and the resource information, wherein the sorted order is based at least in part on the measurement information associated with the plurality of provider UEs 550 determined by apparatus 502.
