Technical Field

[0003] In summary, various aspects of this disclosure relate to wireless communication, and various aspects of this disclosure relate to technologies and apparatus for reporting and utilizing resource availability information. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable 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). LTE / Improved LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with the BS via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the BS to the UE, while an "uplink" (or "backlink") 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 Headend, Transmit / Receive Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. NR (which can also be referred to as 5G) is an enhancement set of the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), thereby better supporting mobile broadband internet access, as well as beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0012] In some aspects, a non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a second UE, cause the second UE to: receive resource availability information from a first UE, the resource availability information including a corresponding plurality of bits indicating availability status in a set of availability statuses for each resource in a resource set; and send communication to the first UE, at least in part, based on receiving the resource availability information from the first UE, to use at least one resource in the resource set.

[0013] In some aspects, an apparatus for wireless communication includes: a unit for monitoring a set of resources to determine a set of availability states for the set of resources; and a unit for transmitting resource availability information to a second apparatus, the resource availability information including a plurality of corresponding bits indicating the availability state in the set of availability states for each resource in the set of resources.

[0027] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or a method may be implemented using any number of the aspects set forth herein. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods implemented using structures, functions, or structures and functions other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0028] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in detail below and illustrated in the accompanying drawings, through various frames, 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 such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0029] It should be noted that while this document may use terms commonly associated with 5G or NR radio access technology (RAT) to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0030] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, as well as other examples. Wireless network 100 may include multiple 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 can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0031] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions. A picocell can cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed User Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1In the examples shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0032] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0033] 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 transmit the data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, repeater, etc.

[0034] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0035] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other via wireless or wired backhaul (e.g., directly or indirectly).

[0036] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, user unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet device, camera, gaming device, netbook, smartbook, ultrabook, medical device or apparatus, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music or video device, or satellite radio unit, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0037] Some UEs can 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, which can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links, for example. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing housing the components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0038] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0039] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using BS 110 as an intermediary for communication with each other). For example, UE 120 may 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, vehicle-to-infrastructure (V2I) protocols, etc.) and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described herein as being performed by BS 110.

[0040] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) (spanning from 410 MHz to 7.125 GHz), and / or can communicate using an operating band with a second frequency range (FR2) (spanning from 24.25 GHz to 52.6 GHz). The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequencies (IFs). Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the "below 6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise explicitly stated, it should be understood that the terms "below 6 GHz" and the like (if used herein) can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the terms "millimeter wave" and the like (if used herein) can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequencies (e.g., less than 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0041] In some aspects, UE 120 may include communication manager 140. As described in more detail elsewhere herein, communication manager 140 may monitor a set of resources to determine a set of availability states for the resource set; and send resource availability information to another UE 120, the resource availability information including a corresponding plurality of bits indicating the availability state in the set of availability states for each resource in the resource set. As described in more detail elsewhere herein, communication manager 140 may receive resource availability information from another UE 120, the resource availability information including a corresponding plurality of bits indicating the availability state in the set of availability states for each resource in the resource set; and send communication to another UE 120 using at least one resource in the resource set, at least in part based on receiving resource availability information from the other UE 120. Additionally or alternatively, communication manager 140 may perform one or more other operations described herein.

[0042] As pointed out above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0043] Figure 2 This is a diagram illustrating an example of communication between a BS 110 and a UE 120 in a wireless network 100 according to the present disclosure. The BS 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein generally, T ≥ 1 and R ≥ 1.

[0044] At BS 110, the transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for that UE based at least in part on the Channel Quality Indicator (CQI) received from each UE, process (e.g., code and modulate) the data for that UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmitting processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, permission, and / or upper-layer signaling), and provide overhead symbols and control symbols. The transmitting processor 220 can 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)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can (e.g., for OFDM) process its corresponding output symbol stream to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t respectively.

[0045] At UE 120, antennas 252a to 252r can receive downlink signals from BS 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Reference Signal Received Power (RSRP) parameter, Received Signal Strength Indicator (RSSI) parameter, Reference Signal Received Quality (RSRQ) parameter, and / or CQI parameter, as well as other examples. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0046] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with BS 110 via communication unit 294.

[0047] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within the following: one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, and other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or multiple antenna elements within housings. 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 (one or more components).

[0048] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting RSRP, RSSI, RSRQ, and / or CQI). Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-encoded (if applicable) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to BS 110. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 254) of UE 120 can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 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 (e.g., as referenced). Figure 6-8 (Described).

[0049] At BS 110, uplink signals from UE 120 and other UEs can 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 transmitted by UE 120. Receive processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. BS 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. BS 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator of BS 110 (e.g., MOD / DEMOD 232) may be included in the modem of BS 110. In some aspects, BS 110 includes a transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 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 (e.g., as referenced). Figure 6-8 (Described).

[0050] The controller / processor 240 of BS 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other components may perform one or more techniques associated with resource availability information reporting and utilization, as described in more detail elsewhere herein. For example, the controller / processor 240 of BS 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can perform or direct, for example Figure 7 The process 700 Figure 8 The operation of process 800 and / or other processes as described herein. Memory 242 and 282 may store data and program code for BS 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, one or more instructions, when executed by one or more processors of BS 110 and / or UE 120 (e.g., directly, or after compilation, translation, and / or interpretation), may cause one or more processors, UE 120, and / or BS 110 to perform or instruct, for example... Figure 7 The process 700 Figure 8 The operation of process 800 and / or other processes as described herein. In some aspects, execution instructions may include run instructions, translation instructions, compilation instructions and / or interpretation instructions, and other examples.

[0053] Although Figure 2 The boxes in the diagram are shown as different components, but the functions described above with respect to these boxes can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by or under the control of controller / processor 280.

[0054] As pointed out above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0055] Figure 3 This is a diagram illustrating example 300 of sidelink communication according to various aspects of this disclosure.

[0056] like Figure 3 As shown, the first UE 305-1 can communicate with the second UE 305-2 (and one or more other UEs 305) via one or more sidelink channels 310. UEs 305-1 and 305-2 can communicate using one or more sidelink channels 310 for P2P communication, D2D communication, V2X communication (e.g., which may include V2V communication, V2I communication, vehicle-to-pedestrian (V2P) communication, mesh networking, etc.), etc. In some aspects, UEs 305 (e.g., UEs 305-1 and / or UEs 305-2) can correspond to one or more other UEs described elsewhere herein, such as UE 120. In some aspects, one or more sidelink channels 310 can use a PC5 interface and / or can operate in a high-frequency band (e.g., the 5.9 GHz band). Alternatively or additionally, UEs 305 can use Global Navigation Satellite System (GNSS) timing to synchronize the timing of transmission time intervals (TTIs) (e.g., frames, subframes, time slots, symbols, etc.).

[0057] like Figure 3 As further shown, one or more sidelink channels 310 may include a Physical Sidelink Control Channel (PSCCH) 315, a Physical Sidelink Shared Channel (PSSCH) 320, and / or a Physical Sidelink Feedback Channel (PSFCH) 325. Similar to the Physical Downlink Control Channel (PDCCH) and / or Physical Uplink Control Channel (PUCCH) used for cellular communication with BS 110 via an access link or access channel, PSCCH 315 may be used to transmit control information. Similar to the Physical Downlink Shared Channel (PDSCH) and / or Physical Uplink Shared Channel (PUSCH) used for cellular communication with BS 110 via an access link or access channel, PSSCH 320 may be used to transmit data. For example, PSCCH 315 may carry sidelink control information (SCI) 330, which may indicate various control information for sidelink communication, such as one or more resources (e.g., time resources, frequency resources, spatial resources, etc.), wherein a transport block (TB) 335 may be carried on PSSCH 320. TB 335 may include data. PSFCH 325 may be used for transmission-side link feedback 340, such as Hybrid Automatic Repeat Request (HARQ) feedback (e.g., ACK / NACK information), Transmit Power Control (TPC), Schedule Request (SR), etc.

[0058] In some aspects, one or more sidelink channels 310 may use resource pools. For example, scheduling assignments may be transmitted across time using specific resource blocks (RBs) in a subchannel (e.g., included in SCI 330). In some aspects, data transmissions associated with scheduling assignments (e.g., on PSSCH 320) may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, scheduling assignments and associated data transmissions are not transmitted on adjacent RBs.

[0059] In some aspects, UE 305 may operate using a transmission mode in which resource selection and / or scheduling is performed by UE 305 (e.g., instead of BS 110). In some aspects, UE 305 may perform resource selection and / or scheduling by sensing the availability of the transmission channels. For example, UE 305 may measure RSSI parameters (e.g., sidelink RSSI (S-RSSI) parameters) associated with various sidelink channels, may measure RSRP parameters (e.g., PSSCH-RSRP parameters) associated with various sidelink channels, may measure RSRQ parameters (e.g., PSSCH-RSRQ parameters) associated with various sidelink channels, and so on, and may select the channel for transmissions used for sidelink communication based at least in part on the measurements.

[0060] Alternatively, UE 305 may use SCI 330 received in PSCCH 315 to perform resource selection and / or scheduling, whereby SCI 320 may indicate occupied resources, channel parameters, etc. Alternatively, UE 305 may perform resource selection and / or scheduling by determining the Channel Busy Rate (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating the maximum number of resource blocks that UE 305 can use for a particular set of subframes).

[0061] In a transport mode where resource selection and / or scheduling is performed by UE 305, UE 305 can generate sidelink grants and can send the grants in SCI 330. Sidelink grants can indicate one or more parameters (e.g., transport parameters) for an upcoming sidelink transport, such as one or more resource blocks (e.g., for TB 335) to be used for the upcoming sidelink transport on PSSCH 320, one or more subframes to be used for the upcoming sidelink transport, MCS to be used for the upcoming sidelink transport, etc. In some aspects, UE 305 can generate sidelink grants indicating one or more parameters for semi-persistent scheduling (SPS), such as the period of the sidelink transport. Alternatively or concurrently, UE 305 can generate sidelink grants for event-driven scheduling (e.g., for on-demand sidelink messages).

[0062] As pointed out above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0063] Figure 4 This is a diagram illustrating example 400 of sidelink communication and access link communication according to various aspects of this disclosure.

[0064] like Figure 4 As shown, the transmitter (Tx) / receiver (Rx) UE 405 and the Rx / Tx UE 410 can communicate with each other via a side link, as described above. Figure 3 As described. Further, in some sidelink modes, BS 110 may communicate with Tx / Rx UE 405 via a first access link. Alternatively, in some sidelink modes, BS 110 may communicate with Rx / Tx UE 410 via a second access link. Tx / Rx UE 405 and / or Rx / Tx UE 410 may correspond to one or more UEs described elsewhere herein, such as... Figure 1Therefore, the direct link between UE 120 (e.g., via the PC5 interface) can be referred to as a sidelink, and the direct link between BS 110 and UE 120 (e.g., via the Uu interface) can be referred to as an access link. Sidelink communication can be transmitted via the sidelink, and access link communication can be transmitted via the access link. Access link communication can be downlink communication (from BS 110 to UE 120) or uplink communication (from UE 120 to BS 110).

[0065] As pointed out above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0066] Figure 5 This is a diagram illustrating example 500 of resource availability sensing according to various aspects of this disclosure.

[0067] like Figure 5 As shown, the transmitting UE (which transmits to the receiving UE) can sense resources within a sliding sensing window. For example, the transmitting UE can sense, at least in part, that a first resource and a second resource are reserved in subsequent transmission windows by other UEs (e.g., besides the transmitting UE) based on the sensing window. In this case, the transmitting UE can decode one or more SCI messages in the sensing window to identify the reservation of the first and second resources. In some aspects, the transmitting UE can determine that the first and second resources are reserved based, at least in part, on the detected received signal level of the corresponding SCI that reserves the first and second resources. In other words, if the received signal level of the SCI that reserves the first resource meets a threshold, the transmitting UE can determine that communication using the first resource may cause interference with another transmission (e.g., by another UE) and can determine that the first resource is reserved. Conversely, if the received signal level does not meet the threshold (or if no SCI is received), the transmitting UE can determine that interference with another transmission is predicted not to occur and can determine that the first resource is not reserved.

[0068] In some cases, the transmitting UE can measure specific quantities to determine whether resources are reserved. For example, the transmitting UE can measure the RSRP level on the PSSCH or PSSCH as described above. For example, the transmitting UE can compare the measured RSRP with an RSRP threshold (e.g., which is configured at least in part based on the transmitting UE's first priority and / or the receiving UE's second priority). However, some transmitting UEs may have limited resources for performing resource availability sensing. For example, the transmitting UE may have limited power resources.

[0069] In this scenario, the receiving UE can perform resource availability sensing and can provide a report of availability information to the sending UE via unicast or multicast communication. The receiving UE can send a binary report indicating whether a resource is identified as available or unavailable by the receiving UE. When the receiving UE determines whether a resource is available, it can use information about the interference level. For example, the receiving UE can measure a first RSRP from a first transmission from the sending UE and a second RSRP from a second transmission from an interfering UE (e.g., another UE that is neither the sending UE nor the receiving UE). Based at least in part on the corresponding RSRP levels, the receiving UE can determine the signal-to-interference ratio (SIR) for communication with both the sending UE and the interfering UE, and can determine whether the SIR indicates that reliable communication between the sending UE and the receiving UE is possible on resources reserved by the interfering UE.

[0070] Based at least in part on sensing that the first and second resources are reserved in subsequent transmission windows, the transmitting UE can reserve a third resource in the transmission window and then use the third resource in the transmission window to transmit to the receiving UE. Similarly, based at least in part on receiving a binary report indicating whether a resource is available or unavailable (from the receiving UE), the transmitting UE can reserve a third resource in the transmission window and then transmit to the receiving UE.

[0071] As pointed out above, Figure 5 This is provided as an example. Other examples may differ from the one provided. Figure 5 The example described.

[0072] However, when providing binary reports to the transmitting UE, the receiving UE may unnecessarily mark resources as reserved. For example, when the transmitting UE has packets (such as high-priority packets or low-latency packets, and other examples), the transmitting UE can be configured to transmit packets even if there is a possibility of interference on resources reserved by, for example, interfering UEs. In this case, the transmitting UE can determine that the probability of interference is greater than the priority or latency level assigned to the packets. Similarly, the transmitting UE may have multiple available power control levels and can be able to adjust the power control levels to ensure reliable transmission even on resources reserved by interfering UEs. However, when the transmitting UE receives a binary report on resource availability, this binary report may lack information that would enable the UE to make decisions about whether to cover resource reservations and transmit regardless of the possibility of interference, or to adjust the power control levels to ensure reliability, and other examples.

[0073] Some aspects described in this article implement enhanced reporting of resource availability. For example, the receiving UE can send... n Bit report, then Bit reports include information on the availability of soft resources (e.g., n > Two different levels of resource availability, their usage n >1 bit to identify the availability of each resource). As an example of a 2-bit report, the receiving UE can send a report identifying a resource as strongly available (e.g., not reserved), weakly available (e.g., reserved but with a corresponding SIR indicating a first threshold reliability level), weakly unavailable (e.g., reserved with a SIR indicating a second lower threshold reliability level), and strongly unavailable (e.g., reserved and not interfered with). Although this paper describes some aspects based on 2-bit reports with a specific set of availability states, for n Bit reports, other bit counts, or other sets of availability status are possible.

[0074] In this case, the transmitting UE can use n Bit reports determine whether a resource is available, unavailable but the transmitting UE can still attempt to transmit on that resource, or unavailable and the transmitting UE will not attempt to transmit on that resource. In this way, the receiving UE and the transmitting UE achieve a higher level of flexibility in resource utilization in the sidelink communication system.

[0075] Figure 6 This is a diagram illustrating example 600 related to resource availability information reporting and utilization according to various aspects of this disclosure. (See diagram 600 for example.) Figure 6 As shown, the first UE 120-1 (e.g., the receiving UE) and the second UE 120-2 (e.g., the transmitting UE) can communicate with each other.

[0076] As in Figure 6 As further illustrated by reference numerals 605 and 610, the first UE 120-1 can monitor the set of resources in a sensing window to attempt to decode one or more SCIs that reserve one or more resources. For example, the first UE 120-1 can receive an SCI in the sensing window and decode the SCI to identify resource reservations (e.g., those of interfering UEs (not shown)) in the transmission window. In some aspects, the first UE 120-1 can perform partial sensing and obtain partial resource availability information. In this case, the first UE 120-1 can estimate resource availability at least partially based on partial sensing.

[0077] As in Figure 6As further illustrated by reference numerals 615 and 620 in the accompanying drawings, the first UE 120-1 can determine available resources in the resource set and can send a resource availability indication to identify available resources. For example, the first UE 120-1 can determine a non-binary resource availability state (e.g., a resource availability state with granularity greater than binary states) and can send... n Bits (for each resource, n ≥2) Resource availability reporting to identify non-binary resource availability status. In this case, the first UE 120-1 can encode the availability status for each resource as... n The value of the bit field, such as a 2-bit indicator, encodes a value of 0 ("00") as strongly unavailable (SN), a value of 1 ("01") as weakly unavailable (WN), a value of 2 ("10") as weakly available (WA), and a value of 3 ("11") as strongly available (SA). Alternatively, the first UE 120-1 may use 3-bit or more bit indicators to encode the availability state to enable another set of possible availability states. In some aspects, n The number of bits used for each resource can be greater than 1. In some respects, n The number of bits can be less than the threshold number, such as less than 3, less than 5, less than 9, less than 17, less than 33 or less than 65, and other examples.

[0078] In some aspects, the first UE 120-1 can be selected n Specific values ​​(e.g., the number of bits used to identify the availability status of each resource and the granularity of the availability status, where 2 n Indicates when using n (The number of possible states of a resource when each bit is used to identify its availability status). For example, when determining and reporting the availability status, the first UE 120-1 can use... n Select a pre-configured value (e.g., a static value). Alternatively, the first UE 120-1 may receive a request from the second UE 120-2 for a specific granularity level and corresponding... n The second UE 120-2 can request the first UE 120-1 to provide a resource availability indication (e.g., a report request), and can include an identifier in the request. n The information regarding the value. Alternatively, the first UE 120-1 may dynamically determine, at least in part, the number of RSRP measurements configured by the second UE 120-2 and / or the BS 110 that configures communication for the first UE 120-1. n The value. In some respects, the first UE 120-1 can be determined dynamically. nThe value, and will be used by the second UE 120-1. n The value is reported to the second UE 120-2 so that the second UE 120-2 can decode the resource availability indication.

[0079] In some respects, n The specific value may be based at least in part on parameters configured for the first UE 120-1. For example, the first UE 120-1 and / or the second UE 120-2 may be determined at least in part based on the number of MCS levels used by the second UE 120-2, the number of priority levels of packets sent by the second UE 120-2, the latency requirements configured for the second UE 120-2 (e.g., packet delay budget (PDB)), or the configuration of the power control level used by the second UE 120-2. n Specific values. Alternatively, the first UE 120-1 and / or the second UE 120-2 may be determined at least in part based on the number of sub-channels occupied for resource availability reporting, the communication range requirements of the first UE 120-1 and / or the second UE 120-2, the physical distance or radio frequency (RF) distance between the first UE 120-1 and the second UE 120-2, or the corresponding area identifiers of the first UE 120-1 and the second UE 120-2, and other examples. n A specific value. Alternatively, the first UE 120-1 and / or the second UE 120-2 may be determined at least in part based on the type of communication to be used by the second UE 120-2 (e.g., unicast, multicast, or broadcast communication), the CBR measured by the first UE 120-1 and / or the second UE 120-2, or whether the second UE 120-2 is configured to use HARQ feedback for transmission, and other examples. n Specific value.

[0080] In some respects, the first UE 120-1 can generate soft availability information for resources based at least in part on the SIR (e.g., n (Bit resource availability status). For example, as described above, the first UE 120-1 can determine the estimated SIR of the target link with the second UE 120-2 in combination with interference transmissions from one or more other UEs. In this case, the first UE 120-1 can use one or more thresholds to determine... n Bit resource availability status. In some aspects, one or more thresholds may be RSRP thresholds, RSSI thresholds, or RSRQ thresholds, and other examples.

[0081] In some respects, the first UE 120-1 may estimate availability information. For example, when the first UE 120-1 performs partial sensing (such as sensing associated with a subset of resources), the first UE 120-1 may estimate the availability of the set of resources, including the subset of resources, based at least in part on the results of the partial sensing, prediction techniques, pattern recognition techniques or artificial intelligence techniques, and other examples.

[0082] In some aspects, the first UE 120-1 can be compressed. n Bit resource availability status. For example, the first UE 120-1 may use source coding techniques or another type of compression technique to compress the set of bits for availability information. In this case, the first UE 120-1 may use less than n m Use bits to represent m A collection of resources n Bit resource availability status.

[0083] As in Figure 6 As further shown by reference numeral 625 in the accompanying drawing, the second UE 120-2 can use resource availability information to determine whether to use a specific resource to transmit information. For example, the second UE 120-2 can at least partially base its information on resource availability information. n The availability of bit resources is used to select resources for transmission. In some respects, the second UE 120-2 can be at least partially based on... n The second UE 120-2 selects resources based on bit resource availability status and parameters. For example, for a relatively high MCS index, the second UE 120-2 can determine that weakly unavailable resources are unavailable, but for a relatively low MCS index, the second UE 120-2 can determine that weakly unavailable resources are available for selection. Similarly, for a relatively low transmit power level, the second UE 120-2 can select only strongly available resources, but at a higher transmit power level, the second UE 120-2 can select either weakly available or weakly unavailable resources. Likewise, the second UE 120-2 can at least partially base its selection on... n The availability of bit resources and packet priority levels, or latency requirements (e.g., PDB), reliability requirements, and other examples, determine whether to use resources for transmission. Alternatively, the second UE 120-2 may determine whether to use resources based at least in part on communication range requirements, distance, radio frequency distance, area identifier, communication type, utilization of CBR or HARQ feedback, and other examples.

[0084] In some aspects, the second UE 120-2 can combine multiple granularities of resource availability information to determine whether to select a resource. For example, the second UE 120-2 can combine multiple granularities of resource availability information to determine whether to select a resource.n Bit availability information mapped to the second m Bit availability information (e.g., where m Unlike n In this case, when information about resources exists at a finer granular level of the corresponding availability information, the second UE 120-2 can use that finer granularity of the corresponding availability information (e.g., m or n (The larger of the two). Conversely, when the finer granularity of the corresponding availability information does not include information about resources, the second UE 120-2 can fall back to using the finer granularity of the corresponding availability information. In some cases, m Bit availability information and n One of the bit availability information may be information generated by the second UE 120-2 at least in part based on the performance sensing, and the other may be information received from the first UE 120-1. In this case, the second UE 120-2 may use the information generated at least in part based on the performance sensing and fall back to the information received from the first UE 120-1.

[0085] In some aspects, the second UE 120-2 may use specific logical combination techniques to combine multiple granularities of resource availability information. For example, the second UE 120-2 may use logical combination (e.g., AND) operations to combine corresponding resource availability information. Alternatively, the second UE 120-2 may average the corresponding resource availability information for each resource. In some aspects, the second UE 120-2 may use a threshold for this combination. For example, the second UE 120-2 may identify only the resource with the minimum availability level in two corresponding resource availability information sets or a single corresponding resource availability information set as available. In this case, the second UE 120-2 may determine the threshold at least in part based on a static value or the percentage of resources marked as available at a specific threshold, and other examples. Alternatively, the second UE 120-2 may adjust the thresholds (e.g., RSRP threshold, RSRQ threshold, or SIR threshold) for generating resource availability information sets at least in part based on, for example, the percentage of resources marked as available. In this way, the second UE 120-2 can ensure that the minimum number of resources in the transmission window is identified as available to meet, for example, latency requirements, PDB or reliability requirements, and other examples.

[0086] In some aspects, the second UE 120-2 can determine resource availability based on compressed resource availability information. For example, the second UE 120-2 can use stored information about a source encoding technique used to compress resource availability to decompress the resource availability information. Alternatively, the second UE 120-2 can use information received from the first UE 120-1 and / or another device to decompress the resource availability information. In some aspects, the second UE 120-2 can use a specific decompression technique to extract resource availability information, such as a source-encoding-based decompression technique or another type of decompression technique.

[0087] As in Figure 6 As further illustrated by reference numeral 630 in the accompanying drawings, the second UE 120-2 may use resources for transmission. For example, based at least in part on the resource availability of an identified resource set, the second UE 120-2 may select and / or reserve resources and use those resources for transmission. In some aspects, the second UE 120-2 may select resources at least in part based on a random selection process. For example, the second UE 120-2 may randomly or pseudo-randomly select any resource marked as strongly available or weakly available. Alternatively or additionally, the second UE 120-2 may apply weighting to resources at least in part based on availability status. For example, the second UE 120-2 may weight strongly available resources more heavily than weakly available resources to increase the likelihood of selecting strongly available resources using a weighted random selection process.

[0088] As pointed out above, Figure 6 This is provided as an example. Other examples may differ from the one provided. Figure 6 The example described.

[0089] Figure 7 This is a diagram illustrating, for example, an example process 700 performed by a first UE according to various aspects of this disclosure. Example process 700 is an example in which the first UE (e.g., UE 120) performs operations associated with resource availability information reporting and utilization.

[0090] like Figure 7 As shown, in some aspects, process 700 may include: monitoring a set of resources to determine a set of availability states for the resource set (box 710). For example, a first UE (e.g., using...) Figure 9 The monitoring component 908 described herein can monitor a set of resources to determine a set of availability states for the set of resources, as described above.

[0091] like Figure 7Further shown, in some aspects, process 700 may include: sending resource availability information to a second UE, the resource availability information including a corresponding plurality of bits indicating the availability status in the availability status set for each resource in the resource set (box 720). For example, a first UE (e.g., using...) Figure 9 The transmitting component 904 described herein can transmit resource availability information to the second UE. The resource availability information includes a plurality of corresponding bits indicating the availability status in the availability status set for each resource in the resource set, as described above.

[0092] Process 700 may include additional aspects, such as any single aspect or any combination thereof described below and / or in conjunction with one or more other process descriptions elsewhere described herein.

[0093] In the first aspect, process 700 includes: receiving communication from the second UE to use at least one resource in a resource set, based at least in part on sending resource availability information to the second UE.

[0094] In the second aspect, either alone or in combination with the first aspect, the corresponding plurality of bits indicating the availability status of the corresponding resource include a two-bit soft resource availability indicator that identifies whether the corresponding resource is classified as strongly available, weakly available, weakly unavailable, or strongly unavailable.

[0095] In the third aspect, either alone or in combination with the first and second aspects, the number of bits in the corresponding plurality of bits is set at least in part based on: the static configuration for the first UE, the dynamic indication of the transmission of request resource availability information from the second UE, the dynamic determination associated with at least one reference signal received power measurement or reference signal received quality measurement, or the dynamic determination reported by the second UE.

[0096] In the fourth aspect, either alone or in combination with the first to third aspects, the number of bits in the corresponding plurality of bits is adjusted from the set value based at least in part on the following: the number of modulation and coding scheme layers, the number of priority levels of the packets, the delay parameter, the reliability parameter, the number of occupied subchannels, the number of power control levels, the communication range parameter, the distance between the first UE and the second UE, the area identifier, the type of communication, the channel busy ratio, or the use of hybrid automatic repeat request feedback.

[0097] In the fifth aspect, either alone or in combination with the first to fourth aspects, process 700 includes: determining a set of availability states based at least in part on the signal-to-interference ratio on the target link with the second UE.

[0098] In the sixth aspect, either alone or in combination with the first to fifth aspects, the signal-to-interference ratio is based at least in part on a measurement of the reference signal received power or the reference signal received quality.

[0099] In the seventh aspect, either alone or in combination with the first to sixth aspects, the corresponding plurality of bits indicating the availability status include an n-bit resource availability indication that identifies whether the resource is classified into one of a plurality of possible availability states, where n > 1.

[0100] In the eighth aspect, either alone or in combination with the first through seventh aspects, process 700 includes: using source coding techniques to compress bits of resource availability information; and transmitting resource availability information based at least in part on the bits of resource availability information compressed using source coding techniques.

[0101] In the ninth aspect, either alone or in combination with the first through eighth aspects, process 700 includes: determining an availability state set based at least in part on partial sensing of the resource set during monitoring of the resource set; and transmitting resource availability information based at least in part on the determination of the availability state set.

[0102] Although Figure 7 An example box of process 700 is shown, but in some aspects, process 700 may include... Figure 7 The boxes depicted in the diagram are compared to additional boxes, fewer boxes, different boxes, or boxes arranged in a different manner. Alternatively, two or more boxes in process 700 may be executed in parallel.

[0103] Figure 8 This is a diagram illustrating, for example, an example process 800 performed by a second UE according to various aspects of this disclosure. Example process 800 is an example in which a second UE (e.g., UE 120) performs operations associated with resource availability information reporting and utilization.

[0104] like Figure 8 As shown, in some aspects, process 800 may include: receiving resource availability information from a first UE, the resource availability information including a corresponding plurality of bits (box 810) indicating the availability status in the availability status set for each resource in the resource set. For example, a second UE (e.g., using...) Figure 9 The receiving component 902 described herein may receive resource availability information from the first UE. The resource availability information includes a plurality of corresponding bits indicating the availability status in the availability status set for each resource in the resource set, as described above.

[0105] like Figure 8Further, in some aspects, process 800 may include: sending communication to the first UE, at least in part, regarding the use of at least one resource in the resource set, based on receiving resource availability information from the first UE (box 820). For example, a second UE (e.g., using...) Figure 9 The transmitting component 904 described herein can transmit communication to the first UE using at least one resource in the resource set, at least in part, based on receiving resource availability information from the first UE, as described above.

[0106] Process 800 may include additional aspects, such as any single aspect or any combination thereof described below and / or in conjunction with one or more other process descriptions elsewhere described herein.

[0107] In the first aspect, the corresponding plurality of bits indicating the availability status of the corresponding resource include a two-bit soft resource availability indicator that identifies whether the corresponding resource is classified as strongly available, weakly available, weakly unavailable, or strongly unavailable.
