[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 983,430, filed on February 28, 2020, entitled “TECHNIQUES FOR SELECTING RESOURCES FROM RESOURCE MAPS OBTAINED FROM NEARBY DEVICES,” and U.S. Non-Provisional Patent Application No. 17 / 249,235, filed on February 24, 2021, entitled “TECHNIQUES FOR SELECTING RESOURCES FROM RESOURCE MAPS OBTAINED FROM NEARBY DEVICES,” which are hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure generally relate to wireless communications and techniques and apparatus for selecting resources from a resource map obtained from nearby devices. 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 such 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) systems. 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 many base stations (BSs) that can support communications for many user equipment (UEs). UEs can communicate with a BS via downlinks and uplinks. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region, and even global levels. 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 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 other open standards that support beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0091] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied 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 thorough and complete and to fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether that aspect is implemented independently of any other aspect of the disclosure or implemented in combination 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 an apparatus or method that uses other structures, functions, or structures and functions in addition to the various aspects of the disclosure set forth herein to practice, or uses other structures, functions, or structures and functions that are different from the various aspects of the disclosure set forth herein to practice. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of the claims.

[0092] 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, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0093] It should be noted that although various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0094] Figure 1 is a schematic diagram illustrating an example of a wireless network 100 according to various aspects of 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 things. The wireless network 100 may include a plurality of base stations 110 (shown 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 the coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0095] 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 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. 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 1In 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 for femtocell 102c. 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.

[0096] In some aspects, the cells may not necessarily be stationary, 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 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0097] 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.

[0098] 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 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 to 2 watts).

[0099] The network controller 130 may be coupled to a group 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, for example, directly or indirectly via a wireless or wired backhaul.

[0100] 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 bracelet)), an entertainment device (e.g., a music or video device or satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0101] 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. For example, a wireless node may provide connectivity to or to a network (e.g., a wide area network such as the Internet or a cellular 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 in 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, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0102] 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.

[0103] 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 mutual communication). 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.

[0104] 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 range from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2), which can range 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 frequency band "below 6 GHz." 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) defined as a "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless otherwise expressly stated, it should be understood that the terms "sub-6 GHz," etc., if used herein, can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise expressly stated, it should be understood that the terms "millimeter wave," etc., if used herein, can 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.

[0105] As mentioned above, providing Figure 1 As an example. Other examples can be related to Figure 1 Different than described.

[0106] Figure 2is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100 in accordance with various aspects of 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.

[0107] At the base station 110, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCSs) for the UEs based at least in part on a channel quality indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for the UEs based at least in part on the MCS(s) selected for each 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 signal (PSS) or secondary synchronization signal (SSS)). A transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​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. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0108] 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 further 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) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0109] 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.

[0110] 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, etc. 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 coplanar antenna element sets and / or non-coplanar antenna element sets. 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 antenna elements coupled to one or more transmitting and / or receiving components such as Figure 2 One or more antenna elements of one or more components).

[0111] 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 a 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 a TX MIMO processor 266 (if applicable), further processed by 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 antenna(s) 252, a modulator and / or demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform various aspects of any of the methods described herein.

[0112] 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 the decoded data to a data sink 239 and the 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 246 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 antenna(s) 234, a modulator and / or demodulator 232, a MIMO detector 236, a receive processor 238, a transmit processor 220, and / or a TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform various aspects of any of the methods described herein.

[0113] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component(s) of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with selecting resources from a resource map obtained from nearby devices, as described in more detail elsewhere herein. Figure 2 Any other component(s) may perform or direct e.g. Figure 4 The operations of process 400 and / or other processes as described herein may be performed. 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 communication. 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, for example, Figure 4

[0066] In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions.

[0114] In some aspects, the first UE 120 may include: means for receiving a set of resource maps from one or more second UEs 120, each resource map in the set of resource maps including resource availability information for a corresponding time window; means for selecting a resource set based at least in part on at least one resource map in the set of resource maps; means for sending a signal using the selected resource set; and / or the like. In some aspects, such means may include in conjunction with 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 the like.

[0115] As mentioned above, providing Figure 2 As an example. Other examples can be related to Figure 2 Different than described.

[0116] In a wireless communication system such as an NR system, a wireless communication device (such as a UE) may determine a resource map that identifies one or more resources available for transmitting a signal in a specific time window (referred to herein as available resources) and / or resources that are not available for transmitting a signal in a specific time window (referred to herein as unavailable resources). For example, the UE may determine the resource map based at least in part on sensing performed by the UE, at least in part on control information received by the UE (e.g., by decoding a resource reservation carried in a control channel), at least in part on identifying repeated transmissions by other wireless communication devices, at least in part on another resource map received by the UE, and the like.

[0117] In some cases, a resource map determined by one or more UEs may be shared with one or more other UEs. For example, a first UE may determine a first resource map based on sensing performed by the first UE and control information received by the first UE, and the first UE may provide the first resource map to one or more other UEs, including a second UE (e.g., via a control channel). In one example, the second UE may use a first resource map associated with identifying available resources for sending a signal. In another example, the second UE may determine a second resource map based on the first resource map and sensing performed by the second UE. Here, the second UE may use a second resource map associated with identifying available resources for sending a signal. In addition, in some cases, the second UE may provide the second resource map to one or more other UEs. Resource map sharing is useful in, for example, distributed systems (e.g., to address hidden node problems or half-duplex limitations).

[0118] In some deployments, a first UE may determine (e.g., based on initial measurements and decoding of first control information) a first resource map and provide the first resource map to a second UE. Next, at some time after determining the first resource map, the first UE may determine (e.g., based on subsequent measurements and decoding of second control information) a second resource map and provide the second resource map to the second UE. In this example, a third UE may determine a third resource map and provide the third resource map to the second UE. Thus, the second UE may receive multiple, possibly overlapping, resource maps from one or more other UEs. The manner in which such a UE processes a set of resource maps associated with identifying a set of resources for transmitting a signal received from one or more other UEs should be defined.

[0119] Some aspects described herein provide techniques and apparatus for selecting resources from one or more resource maps obtained from nearby devices. In some aspects, a first UE may receive a resource map set from one or more second UEs. Here, each resource map in the resource map set may include resource availability information for a corresponding time window. The first UE may select a resource set based at least in part on at least one resource map in the resource map set, and may use the selected resource set to send a signal. Additional details are provided below. In some aspects, when, for example, available resource maps are shared between UEs, the techniques and apparatus described herein reduce the overhead of resource map sharing. In addition, in some aspects, when, for example, unavailable resource maps are shared between UEs, the techniques and apparatus described herein reduce resource conflicts (i.e., selecting the same resource at the same time). In addition, in some aspects, the techniques and apparatus described herein reduce the overall complexity of resource map sharing in a wireless communication system.

[0120] Figure 3A and Figure 3B is a diagram illustrating examples associated with selecting resources from a resource map obtained from one or more nearby devices according to various aspects of the present disclosure.

[0121] like Figure 3A As shown in FIG. 305 , a first UE (eg, a first UE 120, identified as UE0) may receive data from one or more second UEs (eg, one or more second UEs 120, which are Figure 3A In some aspects, as described above, a given UE among the one or more second UEs may determine a given resource map in the set of resource maps based at least in part on sensing performed by the given UE, based at least in part on control information received by the given UE, based at least in part on identifying repeated transmissions by other wireless communication devices, based at least in part on another resource map received by the given UE, etc.

[0122] In some aspects, each resource graph in the resource graph set includes resource availability information for a corresponding time window. For example, Figure 3B And regarding the resource map provided by a specific one UE (UE1) among the one or more second UEs, the first resource map (resource map 0) in the resource map set may identify a resource map starting at time t (0,S) and ends at time t (0,E) One or more available resources and / or one or more unavailable resources in the first time window, and the second resource map in the resource map set (resource Figure 1 ) can be identified starting at time t (1,S) and ends at time t (1,E)One or more available resources and / or one or more unavailable resources in the second time window of , and so on. In some aspects, such as Figure 3B As shown, the time windows of two or more resource maps in a resource map set may overlap, which means that the corresponding two or more resource maps may overlap. In some aspects, two or more resource maps in a resource map set may overlap in frequency and / or time.

[0123] In some aspects, a first UE may periodically or based at least in part on a configuration of one or more second UEs to receive a set of resource maps. For example, one or more second UEs may be configured to determine a resource map at a first time and provide it to the first UE, and to determine another (e.g., updated) resource map at a second time and provide it to the first UE, the second time being a specific amount of time after the first time. Thus, in some aspects, a first UE may periodically and automatically receive a set of resource maps from one or more second UEs. In some aspects, a first UE may receive one or more resource maps based at least in part on requesting one or more resource maps from one or more second UEs.

[0124] like Figure 3A As shown in FIG3 , the first UE may select a resource set based at least in part on at least one resource map in the resource map set. In some aspects, the first UE may further select a resource set based at least in part on a transmit time threshold. In some aspects, the transmit time threshold is the time at which the first UE is to transmit a signal. For example, referring to FIG3 , Figure 3B The sending time threshold is the time corresponding to the receipt of the request to send the signal (denoted as time t req ) plus the budgeted time (denoted as t b ) point in time. Therefore, Figure 3B In the example shown, the sending time threshold is determined by time t req +t b definition.

[0125] In some aspects, the first UE may select a resource set based at least in part on determining that the first UE is to transmit a signal. For example, the first UE may receive a request to transmit a signal (such as an uplink communication, a sidelink communication, a reference signal, or other type of communication) (e.g., from one of the second UEs, from the base station 110, from another UE 120, etc.). In some aspects, the request may indicate that the signal is to be transmitted according to a transmit time threshold. In some aspects, the transmit time threshold may be identified in the request. Alternatively, in some aspects, the transmit time threshold may be configured on the first UE. In some aspects, the first UE may be configured to transmit a given signal according to the transmit time threshold configured on the first UE, meaning that in some aspects, neither an indication of transmitting a signal according to the transmit time threshold nor information identifying the transmit time threshold is included in the request to transmit the signal.

[0126] In some aspects, the first UE may select a set of resources based at least in part on one or more resource maps in the set of resource maps that include information identifying available resources.

[0127] For example, the first UE may receive one or more resource maps that identify available resources, and may receive a request to send a signal. In this example, the first UE may determine whether the time at which the request to send a signal is received is after the end of a time window associated with the latest resource map (e.g., the most recently received resource map, the resource map with the latest end time window, etc.). Here, if the time at which the request to send a signal is received is after the end of a time window associated with the latest resource map, the first UE may determine whether the resource map is received within a threshold amount of time from receiving the request. In other words, the first UE may wait for a threshold amount of time after receiving a request to receive another resource map. Here, if the first UE does not receive another resource map within a threshold amount of time from receiving the request, the first UE may randomly select a resource set. Here, the first UE may randomly select a resource set so that the first UE can send a signal according to a transmit time threshold.

[0128] Continuing with the example above, in some aspects, if the time at which the request to transmit a signal is received is not after the end of a time window associated with the latest resource map, then the first UE may select a resource map set based at least in part on a particular resource map in the resource map set. For example, the first UE may identify a particular resource map in the resource map set that is associated with a time window having a latest start time before the time of receipt of the request to transmit a signal and an end time after the time of receipt of the request. In some aspects, the particular resource map identified by the UE may be the latest resource map. The first UE may then select a resource set based at least in part on the particular resource map. In other words, in some aspects, the first UE may identify a particular resource map (e.g., the latest resource map) on which to select a resource set, and may select a resource set based at least in part on the particular resource map. In some aspects, when the first UE is configured such that the UE does not combine resource map sets that identify available resources, the UE may select a resource set from a particular resource map in the resource map set.

[0129] As an alternative example, in some aspects, if the time at which the request to transmit a signal is received is not after the end of a time window associated with the most recent resource map, the first UE may select a resource set based at least in part on the combined resource map. For example, in some aspects, the UE may be configured such that the UE combines resource map sets that identify available resources (e.g., to create a combined resource map that identifies available resources). Here, the first UE may determine whether a transmit time threshold is at or before an end time associated with the combined resource map. In some aspects, if the transmit time threshold is at or before an end time associated with the combined resource map, the first UE may select a resource set based at least in part on the combined resource map. Alternatively, in some aspects, if the transmit time threshold is after the end time associated with the combined resource map, the first UE may select at least a subset of resources in the resource set from the combined resource map. Here, if additional resources are needed (e.g., if the available resources indicated by the combined resource map are insufficient for transmitting a signal), the UE may randomly select another subset of resources (e.g., a subset of resources that is after the end time of the combined resource map). In these examples, the resource set may be selected so that the first UE can transmit a signal based on the transmit time threshold.

[0130] In some aspects, the first UE may select a set of resources based at least in part on one or more resource maps in the set of resource maps including information identifying unavailable resources.

[0131] For example, the first UE may receive one or more resource maps that identify unavailable resources and may receive a request to transmit a signal. In this example, the first UE may determine whether the reception time of the request to transmit the signal is after the end of the time window of the latest resource map in the resource map set. Here, if the reception time of the request is after the end of the time window of the latest resource map, the first UE may randomly select a resource set. Here, the first UE may randomly select a resource set so that the first UE can transmit the signal according to the transmission time threshold.

[0132] Continuing with the above example, in some aspects, if the time at which the request to transmit the signal is received is not after the end of the time window associated with the most recent resource map, the first UE may combine the resource map sets to generate a combined resource map that identifies unavailable resources, and may randomly select a resource set based at least in part on the combined resource map. In other words, the first UE may randomly select a resource set from resources that are not identified as unavailable by the combined resource map.

[0133] It is worth noting that the above aspects can be applied to situations where one or more resource maps in the resource map set do not include location information associated with the UE providing the corresponding resource map, or where the first UE is configured not to consider location information when selecting a resource set.

[0134] In some aspects, each resource map in the set of resource maps may include location information associated with a UE in the one or more second UEs. That is, in some aspects, each of the resource maps in the set of resource maps may include information identifying the location of the UE that determines the resource map. The location information may include, for example, information identifying the absolute location of the UE (e.g., a set of coordinates), a relative location (e.g., relative to a reference location, relative to the first UE), etc.

[0135] In some aspects, when the resource map set includes location information associated with one or more second UEs and the resource map set identifies available resources, the first UE may select the resource set based at least in part on the latest resource map associated with the nearest UE. For example, the first UE may identify the nearest UE of the one or more second UEs (e.g., the UE of the one or more second UEs closest to the first UE) based at least in part on the location information. Next, the first UE may identify the latest resource map associated with the nearest UE in the resource map set. The first UE may then select the resource set based at least in part on the latest resource map associated with the nearest UE. In this way, the first UE may be configured to utilize the latest resource map associated with the nearest UE.

[0136] In some aspects, when the resource map set includes location information associated with one or more second UEs and the resource map set identifies available resources, the first UE may select the resource set based at least in part on a combined resource map associated with a nearest UE. For example, the first UE may identify the nearest UE of the one or more second UEs based at least in part on the location information. Next, the first UE may identify a subset of resource maps in the resource map set that are associated with the nearest UE, and the subset of resource maps may be combined to generate a combined resource map associated with the nearest UE. The first UE may then select the resource set based at least in part on the combined resource map associated with the nearest UE. In this way, the first UE may be configured to utilize resource maps associated with the nearest UE (and combine them across time).

[0137] In some aspects, when the resource map set includes location information associated with one or more second UEs and the resource map set identifies available resources, the first UE may select the resource set based at least in part on the latest resource map associated with the UE within a threshold distance of the first UE. For example, the first UE may identify one of the one or more second UEs that is within a threshold distance of the first UE based at least in part on the location information. Next, the first UE may identify the latest resource map in the resource map set that is associated with the UE within the threshold distance. The first UE may then select the resource set based at least in part on the latest resource map associated with the UE within the threshold distance. In some aspects, when two or more of the second UEs are within the threshold distance, the first UE may select one of the two or more second UEs (e.g., based at least in part on the freshness of the resource map associated with the two or more second UEs) and may proceed accordingly.

[0138] In some aspects, when the resource map set includes location information associated with one or more second UEs and the resource map set identifies available resources, the first UE may select the resource set based at least in part on a combined resource map associated with one or more UEs within a threshold distance of the first UE. For example, the first UE may identify one or more second UEs within a threshold distance of the first UE based at least in part on the location information. Next, the first UE may identify a subset of resource maps in the resource map set that are associated with the one or more UEs within the threshold distance (e.g., the most recent resource map associated with each of the one or more UEs, the last two resource maps associated with each of the one or more UEs, all resource maps associated with each of the one or more UEs, etc.), and may combine the subset of resource maps to generate a combined resource map associated with the one or more UEs. The first UE may then select the resource set based at least in part on the combined resource map associated with the one or more UEs within the threshold distance of the first UE.

[0139] In some aspects, when the resource map set includes location information associated with one or more second UEs and the resource map set identifies unavailable resources, the first UE may select the resource set based at least in part on the combined resource map. For example, the first UE may combine the resource map sets to generate a combined resource map that identifies unavailable resources. Next, the first UE may identify available resources from the combined resource map (e.g., by identifying resources that are not indicated as unavailable). The first UE may then select the resource set based at least in part on the combined resource map. In this manner, the first UE may utilize all available resource maps and identify all available resources from all available resource maps.

[0140] In some aspects, when the resource map set includes location information associated with one or more second UEs and the resource map set identifies unavailable resources, the first UE may select a resource set based at least in part on the latest resource map. For example, the first UE may identify the latest resource map in the resource map set and may identify available resources based at least in part on the latest resource map (e.g., by identifying resources that are not indicated as unavailable). The first UE may then select a resource set from the identified available resources. In this manner, the first UE may utilize the latest resource map and identify all available resources from the latest resource map.

[0141] In some aspects, the first UE may select a resource set based at least in part on sensing performed by the first UE. For example, in some aspects, the first UE may combine the results of the sensing performed by the first UE with the resource map set combination to create another resource map, and may select a resource set accordingly.

[0142] The first UE may transmit a signal using the one or more selected resources, as indicated by reference numeral 315. For example, after selecting a resource set in the manner described above, the first UE may transmit a signal.

[0143] As mentioned above, providing Figure 3A and Figure 3B As an example. Other examples may differ from the Figure 3A and Figure 3B The example described. For example, although Figure 3A and Figure 3B An example is shown in which a single second UE provides a resource map set to a single first UE, but in another example, two or more second UEs (e.g., multiple second UEs) can provide a resource map set to two or more first UEs (e.g., multiple first UEs) so that the two or more first UEs can select a resource set for sending their respective signals.
