[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 104,860, filed October 23, 2020, entitled "Technologies for Channel Sensing Mode Selection," and U.S. Non-Provisional Patent Application No. 17 / 451,730, filed October 21, 2021, entitled "Technologies for Channel Sensing Mode Selection," which are expressly incorporated herein by reference. Technical Field

[0003] The various aspects of this disclosure generally relate to wireless communication and techniques and apparatus for channel sensing mode selection. 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 can support 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 / LTE-Advanced is a collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication between 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 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 aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to perform communications at the municipal, national, regional, and even global levels. NR, also known as 5G, is a collection of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by using 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 Extended OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation, thereby improving spectral efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0027] 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, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods practiced using structures, functions, or structures and functions other than or in lieu of 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 presented with reference to various devices and technologies. These devices and technologies will be described in detail below and illustrated in the accompanying drawings, using various frames, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. The implementation of these elements 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 1This is a diagram illustrating an example of a wireless network 100 according to this disclosure. In other examples, the wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network. The 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 110 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 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 allow unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and allow restricted access for UEs associated with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells can be called a macro BS. A BS used for picocells can be called a pico BS. A BS used for femtocells can be called a femto BS or a home BS. Figure 1 In 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 is not necessarily stationary; the geographical area of ​​the cell can move depending on the location of the mobile BS. In some respects, the BS can use any suitable transport network to interconnect with each other and / or interconnect with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0033] The wireless communication network 100 may also include relay stations. 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 relays data 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 BS110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, 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 set of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via a backhaul link. The BSs can also communicate with each other via wireless or wired backhaul (e.g., directly or indirectly).

[0036] UEs 120 (e.g., 120a, 120b, 120c) may be distributed across 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 (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio device), an in-vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0037] Some UEs can be considered as 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, instruments, monitors, and / or location tags, which can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node 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. Some UEs can be considered as Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered as 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] Generally, 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, frequency 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 base station 110 as an intermediary for communication with another UE). 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 or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations performed by base station 110 as described elsewhere herein.

[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 frequency (IF) bands. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz" band. Similarly, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) recognized as a "millimeter wave" band by the International Telecommunication Union (ITU), FR2 is often referred to as the "millimeter wave" band. Therefore, unless otherwise explicitly stated, it should be understood that the terms "sub-6 GHz" and the like (if used herein) can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency band 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 frequency band frequencies (e.g., less than 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein can be applied to those modified frequency ranges.

[0041] As pointed out above, providing Figure 1 As an example. Other examples may differ from those regarding... Figure 1 The content described.

[0042] Figure 2 This is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically T ≥ 1 and R ≥ 1.

[0043] At base station 110, transmit processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and decoding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the selected MCS(s) for the UE, and provide data symbols for all UEs. Transmit processor 220 can 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. Transmit 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) and secondary synchronization signal (SSS)). If applicable, the transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) 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 process its corresponding output symbol stream (e.g., for OFDM) 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 are transmitted via T antennas 234a to 234t.

[0044] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can also process the input sample (e.g., for OFDM) to obtain the received symbols. 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. Receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the 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 parameters such as the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), and / or CQI. In some respects, one or more components of the UE 120 may be included in the housing 284.

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 antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmission and / or reception components, such as... Figure 2 One or more components.

[0047] On the uplink, at UE 120, the transmitting 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). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-decoded (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 base station 110. In some aspects, the modulator and demodulator (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(s) 252, modulator and / or demodulator 254, MIMO detector 256, receiver processor 258, transmitter 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.

[0048] At base station 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 receiver processor 238 to obtain decoded data and control information issued by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, UE 110 includes a transceiver. The transceiver may include any combination of antenna(s) 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.

[0049] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2Any and more other components may perform one or more techniques associated with channel sensing mode selection, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any (or more) other components can perform or direct, for example Figure 8 The process 800 Figure 9 The operation of process 900 and / or other processes described herein.

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 may cause one or more processors, UE 120, and / or base station 100 to perform or direct (e.g., directly, or after compilation, translation, and / or interpretation) when executed by one or more processors of base station 110 and / or UE 120.

[0067] As pointed out above, Figure 2 This is provided as an example. Other examples may differ from those provided. Figure 2 Example of the description.

[0068] Figure 3 This is a diagram illustrating example 300 of side-link communication according to this disclosure.

[0069] 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). Additionally or alternatively, 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.).

[0070] 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. PSCCH 315 can be used for communication control information, similar to a Physical Downlink Control Channel (PDCCH) and / or a Physical Uplink Control Channel (PUCCH) for cellular communication with base station 110 via an access link or access channel. PSSCH 320 can be used for communication data, similar to a Physical Downlink Shared Channel (PDSCH) and / or a Physical Uplink Shared Channel (PUSCH) for cellular communication with base station 110 via an access link or access channel. 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.) of transport block (TB) 335 that may be carried on PSSCH 320. TB 335 may include data. PSFCH 325 may be used for communication-side link feedback 340, such as Hybrid Automatic Repeat Request (HARQ) feedback (e.g., Acknowledgment or Negative Acknowledgment (ACK / NACK) messages), Transmit Power Control (TPC), Schedule Request (SR), etc.

[0071] In some aspects, one or more sidelink channels 310 may use resource pools. For example, a specific resource block (RB) may be used to transmit a scheduling allocation in the subchannel in time (e.g., included in SCI 330). In some aspects, data transmission associated with a scheduling allocation (e.g., on PSSCH 320) may occupy adjacent RBs in the same subframe as the scheduling allocation (e.g., using frequency division multiplexing). In some aspects, the scheduling allocation and associated data transmission are not transmitted on adjacent RBs.

[0072] In some aspects, UE 305 may perform operations using a transmission mode in which resource selection and / or scheduling is performed by UE 305 (e.g., not base station 110). In some aspects, UE 305 may perform resource selection and / or scheduling by sensing the availability of channels for transmission. For example, UE 305 may measure RSSI parameters (e.g., sidelink RSSI (S-RSSI) parameters) associated with each sidelink channel, RSRP parameters (e.g., PSSCH-RSRP parameters) associated with each sidelink channel, RSRQ parameters (e.g., PSSCH-RSRQ parameters) associated with each sidelink channel, etc., and may select channels for transmission of sidelink communication based at least in part on this measurement(s).

[0073] Alternatively or additionally, UE 305 may use SCI 330, received in PSCCH 315, which may indicate the occupied resources, channel parameters, etc., to perform resource selection and / or scheduling. Alternatively or additionally, UE 305 may perform resource selection and / or scheduling by determining the Channel Busy Rate (CBR) associated with various sidelink channels that can be used for rate control (e.g., by indicating the maximum number of resource blocks that UE 305 can use for one or more subframes).

[0074] In a transport mode where resource selection and / or scheduling is performed by UE 305, UE 305 can generate a sidelink grant and can send that grant in SCI 330. The sidelink grant can indicate one or more parameters (e.g., transport parameters) to be used for an upcoming sidelink transport, such as one or more resource blocks to be used for an upcoming sidelink transport on PSSCH 320 (e.g., for TB 335), one or more subframes to be used for an upcoming sidelink transport, MCS to be used for an upcoming sidelink transport, etc. In some aspects, UE 305 can generate a sidelink grant indicating one or more parameters (such as the periodicity of the sidelink transport) for semi-persistent scheduling (SPS). Additionally or alternatively, UE 305 can generate a sidelink grant for event-driven scheduling (such as for on-demand sidelink messages).

[0075] As pointed out above, Figure 3 This is provided as an example. Other examples may differ from those provided. Figure 3 The example described.

[0076] Figure 4 This is a diagram illustrating example 400 of sidelink communication and access link communication according to this disclosure.

[0077] 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, base station 110 may communicate with Tx / Rx UE 405 via a first access link. Additionally or alternatively, in some sidelink modes, base station 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 1 UE 120. Therefore, the direct link between UE 120 (e.g., via the PC5 interface) can be referred to as a sidelink, and the direct link between base station 110 and UE 120 (e.g., via the Uu interface) can be referred to as an access link. Sidelink communication can be sent via the sidelink, and access link communication can be sent via the access link. Access link communication can be downlink communication (from base station 110 to UE 120) or uplink communication (from UE 120 to base station 110).

[0078] As pointed out above, Figure 4 Provided as an example. Other examples may be related to... Figure 4 The examples described are different.

[0079] Figure 5 This is a diagram illustrating example 500 of resource allocation for sidelink communication according to this disclosure. Figure 5 As shown, sidelink communication can occur using resource pools. Resource pools can be defined for both sidelink transmission and reception. A resource pool can include one or more subchannels in the frequency domain and one or more time slots in the time domain. For example, the minimum resource allocation in the frequency domain can be a subchannel, and the minimum resource allocation in the time domain can be a time slot. In some aspects, one or more time slots of a resource pool may not be available for sidelink communication. In some aspects, one or more resource pools can be configured (or pre-configured) for sidelink communication between UEs 120.

[0080] As shown by reference numeral 510 in the attached figure, the first UE 120 can transmit resource reservation information (e.g., sidelink grant) in the SCI within the first subchannel and first time slot of the resource pool. The sidelink grant can reserve resources in the first time slot and up to two other future time slots. For example, as... Figure 5 As shown, SCIs transmitted in the first time slot and the first sub-channel can reserve resources for the first UE 120 in the second sub-channel and the fourth time slot, as well as in the third sub-channel and the third time slot.

[0081] As shown by reference numeral 520 in the attached figure, the second UE can send resource reservation information (e.g., sidelink grant) in the SCI during the first time slot occupying multiple sub-channels. The SCI can reserve multiple sub-channels for the second UE 120 in the fourth time slot and the seventh time slot of the resource pool.

[0082] In some aspects, SCIs transmitted by UE 120 (e.g., first UE 120 and / or second UE 120) may reserve non-periodic (e.g., dynamic) or periodic resources. For example, SCIs may reserve resources that repeat periodically as configured. In some aspects, among other examples, the periodicity for periodic sidelink resources may have a value between 0 milliseconds and 1000 milliseconds. In some aspects, it is possible to configure UE 120 to reserve periodic resources on the sidelink channel.

[0083] As pointed out above, Figure 5 This is provided as an example only. Other examples may be related to... Figure 5 The descriptions are different.

[0084] Figure 6 This is a diagram illustrating example 600 of resource selection for sidelink communication according to this disclosure. Figure 6As shown, UE 120 can use a channel sensing process to select resources for sidelink communication, such as those combined with the above. Figure 3 As described.

[0085] like Figure 6 As shown, UE 120 can perform a channel sensing process within sensing window 605. In some cases, the sensing window can be 100 milliseconds (e.g., for aperiodic resource reservations, such as aperiodic reservations in one or more slots up to 32 logical slots in the future) or 1100 milliseconds (e.g., for periodic resource reservations). In some cases, UE 120 configured for communication in an NR network can use sensing processes for either aperiodic or periodic resource reservations.

[0086] Based on the channel sensing process, UE 120 can decode control messages related to resource reservations with other UE 120s, and perform measurements associated with one or more sidelink channels (e.g., RSRP measurement and / or RSSI measurement, etc.). For example, other UE 120s can send indications of the current time slot (e.g., the time slot in which reservation information is sent) and one or more (e.g., up to two) future time slots (e.g., as combined with...). Figure 5 The resource reservation information (e.g., in the SCI) described herein. UE 120 can monitor and decode the reservation information during sensing window 605 to determine the channel availability of the sidelink channel (e.g., determine available resources).

[0087] like Figure 6 As shown, UE 120 can determine the resources to be selected for sidelink communication based at least in part on resource selection trigger 610. For example, resource selection can be triggered when UE 120 has packets to be transmitted, or when UE 120 receives an indication to select (or reselect) resources for packets to be transmitted by UE 120. Based at least in part on resource selection trigger 610, UE 120 can determine one or more resources available for selection in resource selection window 615. That is, UE 120 can determine one or more available resources based at least in part on a channel sensing process performed by UE 120. For example, the channel sensing process can provide an indication of occupied resources in resource selection window 615 and / or resources associated with high interference in resource selection window 615.

[0088] The sensing window 605 may be based, at least in part, on timing associated with the resource selection trigger 610. For example, as shown by reference numeral 620, the sensing window may begin at a time T0 from the resource selection trigger 610. As shown by reference numeral 625, the sensing window 605 may begin at a time T0 from the resource selection trigger 610. proc,0 End of section. (T)proc,0 This can be based, at least in part, on the processing time associated with UE 120. In other words, UE 120 can continuously execute the channel sensing process associated with the sidelink channel described above. When UE 120 is triggered to select resources for sidelink communication, UE 120 can consider reserved information and / or measurements associated with the channel sensing process received and / or executed during the channel sensing window 605.

[0089] As shown by reference numerals 630 and 635 in the attached figures, if resource selection trigger 610 occurs at time n, then the resource selection window 615 can range from n+T1 to n+T2. In some respects, T1 can be less than the processing time associated with UE 120 (T... proc,1 In some respects, T2 can be greater than or equal to T. 2,min T 2,min It can be a value configured for the UE based at least in part on the priority of UE 120, and less than or equal to the remaining packet delay budget (PDB) of the packets to be sent by UE 120.

[0090] In some respects, UE 120 can perform resource selection of the sidelink channel according to different channel sensing modes. For example, the first channel sensing mode can be a full-channel sensing mode, where the channel sensing window occurs before resource selection is triggered in the time domain (e.g., as combined above). Figure 6 (As described). In some aspects, the second channel sensing mode can be an on-demand channel sensing mode, where the channel sensing window occurs after a resource selection trigger appears in the time domain. For example, UE 120 can be triggered to select a resource associated with sidelink communication, and the channel sensing process can be performed after receiving the resource selection trigger (e.g., within a sensing window that can be expanded for retransmission). In some examples, the on-demand channel sensing mode can be a channel sensing mode associated with initiating sensing after a resource selection trigger without a defined window (e.g., where UE 120 continuously checks whether the selected resource is available after selecting the resource). UE 120 operating in full-channel sensing mode or on-demand channel sensing mode can be enabled to perform the channel sensing process over the entire sidelink bandwidth. As a result, the reliability of sidelink communication transmitted by UEs operating in full-channel sensing mode or on-demand channel sensing mode can be improved. However, performing the channel sensing process may increase the latency associated with communication and / or may be computationally intensive and consume a significant amount of UE 120's processing resources.

[0091] The third channel sensing mode can be a random selection mode in which UE 120 does not perform a channel sensing process. For example, UE 120 may not perform a sensing process within a sensing window and may select resources (e.g., randomly) within a resource selection window. Therefore, when using the random selection mode, UE 120 can determine that all resources in the resource selection window are candidates for selection, and UE 120 can report one or more candidates to higher layers for use. As a result, latency associated with sidelink communication performed by using UE 120 operating in random selection mode can be reduced. However, UE 120 operating in random selection mode may experience high-rate resource conflicts (e.g., resources reserved by UE 120 operating in random selection mode may overlap with resources reserved by other UE 120s in the time and / or frequency domains), leading to reduced reliability associated with sidelink communication.

[0092] Therefore, in some cases, it may be desirable for UE 120 to change the channel sensing mode in which it operates for sidelink communication. However, the channel sensing mode of UE 120 may not be flexible. For example, the channel sensing mode of UE 120 may be set or otherwise fixed (such as through the configuration of UE 120), and UE 120 may not be able to change its channel sensing mode. As a result, UE 120 may consume processing resources and / or may increase the latency of sidelink communication (e.g., when UE 120 operates in full-channel sensing mode or on-demand channel sensing mode) or may reduce the reliability of sidelink communication (e.g., when UE 120 operates in random selection mode).

[0093] Some of the technologies and apparatus described herein enable channel sensing mode selection for UE 120. For example, UE 120 may be enabled to perform selection among multiple channel sensing modes for sidelink communication. UE 120 may identify or select a channel sensing mode based at least in part on one or more QoS parameters for sidelink communication (e.g., transmission priority, PDB, and / or remaining PDB, etc.). Additionally or alternatively, UE 120 may identify or select a channel sensing mode based at least in part on power constraints associated with UE 120, such as battery level, power draw, and / or thermal constraints of UE 120.

[0094] As a result, UE 120 can be enabled to change the channel sensing mode in which UE 120 operates for sidelink communication. For example, when the sidelink communication transmitted by UE 120 is latency-sensitive, UE 120 can select a channel sensing mode that reduces latency. When the sidelink communication transmitted by UE 120 is associated with high reliability requirements or has high priority, UE 120 can select a channel sensing mode that increases the reliability of the sidelink communication. UE 120 can select a channel sensing mode that consumes fewer processing resources, at least in part, based on the power constraints of UE 120. By enabling UE 120 to select the channel sensing mode in which UE 120 operates, UE 120 can be enabled to adapt the channel sensing mode to the QoS parameters of the sidelink communication and / or the power constraints of UE 120, thereby improving the performance of the sidelink communication and UE 120.

[0095] As pointed out above, Figure 6 Provided as an example. Other examples may differ from those provided. Figure 6 The content described.

[0096] Figure 7 This is a diagram illustrating an example 700 associated with channel sensing mode selection according to this disclosure. Figure 7 As shown, transmitter device 705 and UE 120-1 can communicate with each other. Transmitter device 705 can be base station 110, radio node (such as an Integrated Access and Backhaul (IAB) node), UE 120, or roadside unit (RSU), etc. UE 120-1 and UE 120-2 can communicate with each other. For example, UE 120-1 and UE 120-2 can communicate on the sidelink channel, as described above. Figures 3-6 As described.

[0097] As indicated by reference numeral 710 in the accompanying drawings, transmitter device 705 can transmit information to be used by UE 120-1, and UE 120-1 can receive this information to determine the channel sensing mode to be used by UE 120-1. For example, UE 120-1 can be configured with multiple channel sensing modes for selecting resources on the side-link channel, such as those combined as described above. Figure 6The description includes full-channel sensing modes, on-demand channel sensing modes, and / or random selection modes. In some aspects, transmitter device 705 can send a configuration indicating multiple channel sensing modes to UE 120-1. In some aspects, multiple channel sensing modes can be configured (or pre-configured) in UE 120-1. For example, UE 120-1 can identify one or more channel sensing modes based at least in part on a receive resource pool configuration (e.g., a configuration sent to indicate or define the resource pool) and / or at least on a pre-configuration stored by UE 120-1. The pre-configuration can be associated with information or channel sensing modes defined by wireless communication standards such as 3GPP or otherwise fixed.

[0098] In some aspects, such as Figure 7 As indicated by the dashed arrow depicted herein, transmitter device 705 may not transmit an indication of information to be used by UE 120-1 to determine the channel sensing mode to be used by UE 120-1. For example, the information indicated by transmitter device 705 as described herein, to be used by UE 120-1 to identify or select the channel sensing mode to be used by UE 120-1, can be identified by UE 120-1 in its configuration (or pre-configuration) (e.g., in the absence of an indication from transmitter device 705). For example, the information to be used by UE 120-1 to identify or select the channel sensing mode to be used by UE 120-1 can be defined by wireless communication standards such as 3GPP or otherwise fixed.

[0099] In some aspects, the information used by UE 120-1 to identify or select the channel sensing mode to be used by UE 120-1 may include one or more QoS parameter thresholds (e.g., one or more thresholds associated with one or more parameters related to the QoS of communications to be transmitted by UE 120-1) and / or one or more power constraint parameters. For example, transmitter device 705 may determine one or more QoS parameter thresholds. One or more QoS parameter thresholds may include a first QoS parameter threshold associated with the transmission priority level of the communication, a second QoS parameter threshold associated with the packet delay budget value of the communication, and / or a third QoS parameter threshold associated with the remaining packet delay budget value of the communication, and so on. Transmitter device 705 may send an indication of one or more QoS parameter thresholds to UE 120-1. As described above, UE 120-1 may determine (or identify) one or more QoS parameter thresholds and / or may determine (or identify) one or more power constraint parameters without an indication from transmitter device 705 (e.g., at least in part based on the configuration of UE 120-1).

[0100] In some aspects, the information to be used by UE 120-1 to identify or select the channel sensing mode to be used by UE 120-1 may include an indication of whether UE 120-1 will be enabled to change the channel sensing mode of UE 120-1 and / or an indication of one or more permitted channel sensing modes of UE 120-1. For example, transmitter device 705 may determine whether UE 120-1 will be enabled to change the channel sensing mode of UE 120-1. If UE 120-1 is enabled to change its sensing mode, transmitter device 705 may determine one or more permitted channel sensing modes for UE 120-1. For example, UE 120-1 is capable of operating in one or more channel sensing modes, and transmitter device 705 may determine at least one channel sensing mode from the one or more channel sensing modes in which UE 120-1 is permitted to operate. As described above, in some respects, UE 120-1 can determine one or more permitted channel sensing modes of UE 120-1 without indication from transmitter device 705 (e.g., based at least in part on the configuration of UE 120-1), and / or can determine whether UE 120-1 is enabled to change the sensing mode of UE 120-1.

[0101] Therefore, the information used by UE 120-1 to identify or select the channel sensing mode to be used by UE 120-1 may include one or more parameters for UE 120-1, one or more thresholds, and / or indications of one or more permitted channel sensing modes. For example, the information used by UE 120-1 to identify or select the channel sensing mode to be used by UE 120-1 may include indications of one or more permitted channel sensing modes for UE 120-1 and indications of one or more QoS parameter thresholds to be used by UE 120-1 for selecting the channel sensing mode from one or more permitted channel sensing modes.

[0102] In some aspects, transmitter device 705 can determine the channel sensing mode in which UE 120-1 will operate. In this case, the information used by UE 120-1 to identify or select the channel sensing mode to be used by UE 120-1 may include an indication of the channel sensing mode in which UE 120-1 will operate. Therefore, in some aspects, UE 120-1 may be enabled to change the channel sensing mode in which UE 120-1 operates, at least in part, based on an indication from another device (e.g., transmitter device 705).

[0103] As shown by reference numeral 715 in the attached figure, UE 120-1 can identify or select a channel sensing mode for one or more communications on the sidelink channel from one or more channel sensing modes for sensing channel availability on the sidelink channel. As described above, one or more channel sensing modes may include the combination described above. Figure 6 The description includes full-channel sensing modes, on-demand channel sensing modes, and / or random selection modes. UE 120-1 may identify or select a channel sensing mode from one or more channel sensing modes based at least in part on information that UE 120-1 will use to identify or select the channel sensing mode to be used by UE 120-1. This information may be indicated to UE 120-1 by another device (e.g., transmitter device 705) or may be identified by UE 120-1 in its configuration.

[0104] In some aspects, UE 120-1 can determine whether UE 120-1 is enabled to change its channel sensing mode. For example, UE 120-1 can be configured to be enabled to change, or to prevent, changing its channel sensing mode. In some aspects, UE 120-1 can receive an indication from transmitter device 705 as to whether UE 120-1 is enabled to change its channel sensing mode. In some aspects, UE 120-1 can determine whether it is enabled to change its channel sensing mode without receiving an indication from another device (e.g., at least in part based on a configuration sent to UE 120-1).

[0105] In some aspects, UE 120-1 may determine one or more permitted channel sensing modes in which UE 120-1 is permitted to operate. For example, if UE 120-1 is enabled to change its channel sensing mode, UE 120-1 may be configured with one or more permitted channel sensing modes. For example, UE 120-1 may be permitted to operate in full channel sensing mode and on-demand channel sensing mode, but not in random selection mode. In some aspects, UE 120-1 may be permitted to operate in on-demand channel sensing mode and random selection mode, but not in full channel sensing mode. In some aspects, UE 120-1 may be configured with only one permitted channel sensing mode (e.g., indicating that UE 120-1 is not permitted to change its channel sensing mode). In some aspects, UE 120-1 may receive an indication of one or more permitted channel sensing modes from transmitter device 705. In some respects, UE 120-1 can determine (or identify) one or more permitted channel sensing modes (e.g., based at least in part on the configuration sent to UE 120-1) without receiving instructions from another device.

[0106] In some aspects, UE 120-1 can identify or select a channel sensing mode from one or more channel sensing modes, at least in part, based on the values ​​of one or more parameters related to the QoS of communications to be transmitted by UE 120-1. The one or more parameters related to QoS may include a transmission priority level associated with the communication, a PDB associated with the communication, and / or a remaining PDB associated with the communication, etc. UE 120-1 can determine one or more parameters from the QoS associated with the communication, and / or derive one or more parameters from the QoS associated with the communication. For example, UE 120-1 can determine (or identify) a transmission priority threshold. UE 120-1 can determine the transmission priority level associated with the communication. UE 120-1 can determine whether the transmission priority level associated with the communication meets the transmission priority level threshold. In some aspects, if the transmission priority level associated with the communication meets the transmission priority level threshold, UE 120-1 can identify that UE 120-1 will operate in on-demand channel sensing mode or full channel sensing mode. If the transmission priority level associated with the communication does not meet the transmission priority level threshold, UE 120-1 can recognize that UE 120-1 will operate in random selection mode.

[0107] In some aspects, UE 120-1 can determine (or identify) a PDB threshold. UE 120-1 can determine the PDB value associated with communication. UE 120-1 can determine whether the PDB value associated with communication meets the PDB threshold. In some aspects, if UE 120-1 determines that the PDB value associated with communication meets the PDB threshold, then UE 120-1 can identify that UE 120-1 will operate in on-demand channel sensing mode or full channel sensing mode. If UE 120-1 determines that the PDB value associated with communication does not meet the PDB threshold, then UE 120-1 can identify that UE 120-1 will operate in random selection mode. In some aspects, the PDB threshold can be based at least in part on the size of the sensing window associated with at least one of the channel sensing modes. For example, if the on-demand channel sensing mode is associated with a sensing window of 100 milliseconds, then the PDB threshold can be less than or equal to 100 milliseconds.

[0108] In some respects, UE 120-1 can determine (or identify) the remaining PDB threshold. UE 120-1 can determine the remaining PDB value associated with the communication. The remaining PDB value can be less than or equal to the PDB value associated with the communication. For example, when UE 120 is triggered to send a communication, the PDB value of the communication can begin to run. UE 120-1 can determine the remaining PDB value of the communication because, in some cases, resource selection triggering can occur after the PDB of the communication has begun to run. UE 120-1 can determine whether the remaining PDB value associated with the communication meets the remaining PDB threshold. In some respects, if UE 120-1 determines that the remaining PDB value associated with the communication meets the remaining PDB threshold, then UE 120-1 can identify that UE 120-1 will operate in on-demand channel sensing mode or full channel sensing mode. If UE 120-1 determines that the remaining PDB value associated with the communication does not meet the remaining PDB threshold, then UE 120-1 can identify that UE 120-1 will operate in random selection mode. In some respects, the remaining PDB threshold can be based at least in part on the size of the sensing window associated with at least one of the channel sensing modes. For example, if the on-demand channel sensing mode is associated with a sensing window of 100 milliseconds, the remaining PDB threshold can be less than or equal to 100 milliseconds.

[0109] In some aspects, UE 120-1 can determine, identify, and / or obtain the aforementioned thresholds (e.g., one or more transmission priority level thresholds, one or more PDB thresholds, and / or one or more remaining PDB thresholds) from the configuration sent to UE 120-1. In some aspects, this configuration can be sent to UE 120-1 by transmitter device 705 (or another device). In some aspects, hard decoding of the configuration can be performed in UE 120-1. In some aspects, the aforementioned thresholds (e.g., one or more transmission priority level thresholds, one or more PDB thresholds, and / or one or more remaining PDB thresholds) can be predefined thresholds. Predefined thresholds can be thresholds defined by wireless communication standards (such as 3GPP specifications) or otherwise fixed.

[0110] In some aspects, UE 120-1 can identify or select a channel sensing mode from one or more channel sensing modes, at least in part, based on one or more power constraint parameters. The one or more power constraint parameters may include battery level parameters, power source parameters (e.g., indicating the power source of UE 120-1, such as power from battery power, external power, and / or AC power), power draw parameters, and / or thermal constraint parameters, etc. UE 120-1 can determine values ​​associated with one or more power constraint parameters. UE 120-1 can identify or select a channel sensing mode from one or more channel sensing modes, at least in part, based on the values ​​associated with one or more power constraint parameters. For example, if the values ​​associated with one or more power constraint parameters indicate that UE 120-1 has low power, has power from an unreliable or limited source (such as battery power), is experiencing high power draw, and / or is experiencing high thermal temperatures, then UE 120-1 can identify that UE 120-1 will operate in a randomly selected mode (e.g., conserve power and / or reduce the thermal temperature of UE 120). If the value associated with one or more power constraint parameters indicates that UE 120-1 has high power, has power from a reliable power source (such as AC power), is experiencing low power draw, and / or is experiencing low thermal temperature, then UE 120-1 can identify that UE 120-1 will operate in on-demand channel sensing mode or full channel sensing mode.

[0111] In some respects, UE 120-1 may determine a channel sensing mode from one or more channel sensing modes based at least in part on an instruction from another device, such as transmitter device 705. For example, as described above, transmitter device 705 may instruct UE 120-1 on the channel sensing mode to be used.

[0112] As shown by reference numeral 720 in the attached figure, UE 120-1 can select resources for sidelink communication based on the determined channel sensing mode. For example, if UE 120-1 determines that it will operate in full channel sensing mode, UE 120 can perform a channel sensing process and can determine the channel availability of the sidelink channel based at least in part on a sensing window that occurs in the time domain before the resource selection associated with sidelink communication is triggered (e.g., as described above). Figure 6 (As described). The UE 120-1 can select one or more resources for sidelink communication from the resource selection window, at least in part, based on the execution of a channel sensing process.

[0113] If UE 120-1 recognizes that it will operate in on-demand channel sensing mode, UE 120 can perform a channel sensing process and can determine the channel availability of the sidelink channel based at least in part on a sensing window that appears in the time domain after a resource selection associated with sidelink communication is triggered. UE 120-1 can select one or more resources for sidelink communication from the resource selection window based at least in part on performing the channel sensing process.

[0114] If UE 120-1 recognizes that it will operate in random selection mode, then UE 120 may not perform the channel sensing process. UE 120-1 can select one or more resources for sidelink communication from the resource selection window (e.g., randomly).

[0115] As shown by reference numeral 725 in the accompanying figure, UE 120-1 can use one or more selected resources to transmit sidelink communication to UE 120-2 on the sidelink channel. As a result, UE 120-1 can be enabled to change the channel sensing mode in which UE 120-1 operates for sidelink communication. For example, when the sidelink communication transmitted by UE 120-1 is latency-sensitive, UE 120-1 can select a channel sensing mode that reduces latency. When the sidelink communication transmitted by UE 120-1 is associated with high reliability requirements or has high priority, UE 120-1 can select a channel sensing mode that increases the reliability of the sidelink communication. UE 120-1 can select a channel sensing mode that consumes fewer processing resources, at least in part, based on UE 120-1's power constraints. By enabling UE 120-1 to select the channel-sensing mode in which UE 120 operates, UE 120-1 can be enabled to adapt the channel-sensing mode to the QoS parameters of sidelink communication and / or the power constraints of UE 120-1, thereby improving the performance of sidelink communication and UE 120-1.
