Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to Greek non-provisional patent application No. 20220100818, filed on October 5, 2022, entitled "SIDELINK CONGESTION CONTROLFOR SENSING AND DATA TRANSMISSIONS", which is hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for sidelink congestion control for sensing and data transmission. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies 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 set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. A "downlink" (or "DL") refers to the communication link from a base station to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a base station.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectrum efficiency; reducing costs; improving services; utilizing new spectrum; and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink to better integrate with other open standards; and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0023] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method that is practiced using other structures, functions, or structures and functions in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0024] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0025] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).

[0026] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d), a user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. The base station 110 is an entity that communicates with the UE 120. The base station 110 (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transmit receive point (TRP). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​a base station 110 and / or a base station subsystem serving the coverage area, depending on the context in which the term is used.

[0027] Base station 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femto cell (e.g., UE 120 in a closed subscriber group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or a home base station. In Figure 1 In the example shown in , BS 110a may be a macro base station for macro cell 102a, BS 110b may be a pico base station for pico cell 102b, and BS 110c may be a femto base station for femto cell 102c. A base station may support one or more (eg, three) cells.

[0028] In some examples, the cell may not necessarily be fixed, and the geographical area of ​​the cell may move according to the location of the mobile base station 110 (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected with each other and / or to one or more other base stations 110 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).

[0029] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a base station 110 or a UE 120) and transmit transmissions of data to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in FIG, BS 110d (eg, a relay base station) may communicate with BS 110a (eg, a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. Base station 110 that relays communication may be referred to as a relay station, relay base station, relay, or the like.

[0030] The wireless network 100 may be a heterogeneous network including different types of base stations 110, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro base station may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0031] A network controller 130 may be coupled to or in communication with a set of base stations 110 and may provide coordination and control for the base stations 110. The network controller 130 may communicate with the base stations 110 via backhaul communication links. The base stations 110 may also communicate directly with each other or indirectly via wireless or wired backhaul communication links.

[0032] UE 120 may be distributed throughout wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 may be a cellular phone (e.g., a smart phone), 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, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, and / or any other suitable device configured to communicate via a wireless medium.

[0033] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0034] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0035] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more side link channels. 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, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0036] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways with various components or constituent parts. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element, a base station, or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR base station (BS), a 5G NB, a gNodeB (gNB), an access point (AP), a TRP, or a cell) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also known as a stand-alone base station or a monolithic base station) or a decomposed base station. A "network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more central units (CU), one or more distributed units (DU), one or more radio units (RU), or a combination thereof).

[0037] A converged base station may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed in one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may also be implemented as a virtual unit (e.g., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU)).

[0038] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (network configurations such as those initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A disaggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a disaggregated base station may be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0039] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "below 6 GHz" band in various documents and articles. A similar naming problem sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0040] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz to 71GHz), FR4 (52.6GHz to 114.25GHz) and FR5 (114.25GHz to 300GHz). Each of these higher frequency bands falls within the EHF band.

[0041] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0042] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may determine a first CBR associated with one or more data transmissions detected within a first time period; determine a second CBR associated with one or more sensing transmissions detected within a second time period that at least partially overlaps the first time period; and send communications based at least in part on the first CBR and the second CBR. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0043] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The content described is different.

[0044] Figure 2 2 is a diagram illustrating an example 200 of base station 110 communicating with UE 120 in wireless network 100 according to the present disclosure. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0045] At the base station 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQI) received from the UE 120. The base station 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0046] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the base station 110 and / or other base stations 110, and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0047] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0048] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0049] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 3 to 8 )Aspects of any of the methods described herein.

[0050] At the base station 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232 shown as DEMOD), detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the base station 110 may include a modulator and a demodulator. In some examples, the base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 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 operations described herein (e.g., with reference to Figures 3 to 8 )Aspects of any of the methods described herein.

[0051] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the base station 110 may perform one or more techniques associated with sidelink congestion control for sensing and data transmission, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 7 700 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for base station 110 and UE 120, respectively. In some examples, 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 base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example Figure 7 The process 700 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0052] In some aspects, the UE includes means for determining a first CBR associated with one or more data transmissions detected in a first time period; means for determining a second CBR associated with one or more sensing transmissions detected in a second time period that at least partially overlaps with the first time period; and / or means for transmitting communications based at least in part on the first CBR and the second CBR. Means for the UE to perform operations described herein may include, for example, one or more of the following: communications manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0053] Although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0054] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The content described is different.

[0055] Figure 3is a diagram illustrating an example 300 of sidelink communications according to the present 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 side link channels 310. UEs 305-1 and 305-2 can communicate using one or more side link channels 310 for P2P communication, D2D communication, V2X communication (e.g., which may include V2V communication, V2I communication and / or V2P communication) and / or mesh networks. In some aspects, UE 305 (e.g., UE 305-1 and / or UE 305-2) may correspond to one or more other UEs described elsewhere herein, such as UE 120. In some aspects, one or more side link channels 310 may use a PC5 interface and / or may operate in a high frequency band (e.g., a 5.9 GHz band). Additionally or alternatively, UE 305 may use global navigation satellite system (GNSS) timing to synchronize the timing of a transmit time interval (TTI) (e.g., a frame, subframe, time slot, or symbol).

[0057] like Figure 3 As further shown, the 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. The PSCCH 315 may be used to communicate control information, similar to a physical downlink control channel (PDCCH) and / or a physical uplink control channel (PUCCH) used for cellular communication with the base station 110 via an access link or access channel. The PSSCH 320 may be used to communicate data, similar to a physical downlink shared channel (PDSCH) and / or a physical uplink shared channel (PUSCH) used for cellular communication with the base station 110 via an access link or access channel. For example, the 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, and / or space resources), wherein a transport block (TB) 335 may be carried on the PSSCH 320. The TB 335 may include data. The PSFCH 325 may be used to communicate sidelink feedback 340, such as hybrid automatic repeat request (HARQ) feedback (eg, acknowledgement or negative acknowledgement (ACK / NACK) information), transmit power control (TPC), and / or scheduling request (SR).

[0058] Although shown on PSCCH 315, in some aspects, SCI 330 may include multiple communications in different levels, such as a first level SCI (SCI-1) and a second level SCI (SCI-2). SCI-1 may be sent on PSCCH 315. SCI-2 may be sent on PSSCH 320. SCI-1 may include, for example, an indication of one or more resources (e.g., time resources, frequency resources, and / or space resources) on PSSCH 320, information for decoding sidelink communications on PSSCH, a quality of service (QoS) priority value, a resource reservation period, a PSSCH DMRS pattern, an SCI format for SCI-2, a beta offset for SCI-2, a number of PSSCH DMRS ports, and / or an MCS. SCI-2 may include information associated with data transmission on PSSCH 320, such as a HARQ process ID, a new data indicator (NDI), a source identifier, a destination identifier, and / or a channel state information (CSI) report trigger.

[0059] In some aspects, one or more sidelink channels 310 may use a resource pool. For example, a scheduling assignment (e.g., included in SCI 330) may be sent in a subchannel across time using specific resource blocks (RBs). In some aspects, data transmissions associated with a scheduling assignment (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, the scheduling assignment and the associated data transmission are not sent on adjacent RBs.

[0060] In some aspects, the UE may be configured with one or more sidelink resource pools by a higher layer. The sidelink resource pool may be used for the transmission and reception of PSCCH / PSSCH and may be associated with sidelink resource allocation mode 1 or mode 2. In the frequency domain, the sidelink resource pool may include a certain number of continuous subchannels. The size of each subchannel may be fixed and may include N continuous RBs. Both the number of subchannels and the subchannel size may be preconfigured by a higher layer (e.g., by radio resource control (RRC)). In some aspects, for possible subchannel sizes, the sidelink may support N=10, 15, 20, 25, 50, 75, and 100 RBs. In the time domain, the time slots available for the sidelink may be determined by repeating the sidelink bitmap (e.g., preconfigured). As used herein, a sidelink resource may refer to a single time slot-subchannel combination and may include RBs within a single subchannel (in the frequency domain) and on a single time slot (in the time domain).

[0061] In some aspects, the UE 305 may operate using a sidelink transmission mode (e.g., Mode 1) where resource selection and / or scheduling is performed by the base station 110. For example, the UE 305 may receive a grant (e.g., in downlink control information (DCI) or in an RRC message, such as for a configured grant) from the base station 110 for sidelink channel access and / or scheduling. In some aspects, the UE 305 may operate using a transmission mode (e.g., Mode 2) where resource selection and / or scheduling is performed by the UE 305 (e.g., instead of the base station 110). In some aspects, the UE 305 may perform resource selection and / or scheduling by sensing channel availability for transmission. For example, UE 305 may measure RSSI parameters associated with various side link channels (e.g., sidelink-RSSI (S-RSSI) parameters), may measure RSRP parameters associated with various side link channels (e.g., PSSCH-RSRP parameters), and / or may measure RSRQ parameters associated with various side link channels (e.g., PSSCH-RSRQ parameters), and may select a channel for sending side link communications based at least in part on the measurements.

[0062] Additionally or alternatively, the UE 305 may perform resource selection and / or scheduling using the SCI 330 received in the PSCCH 315, which may indicate occupied resources and / or channel parameters. Additionally or alternatively, the UE 305 may perform resource selection and / or scheduling by determining a CBR associated with each sidelink channel, which may be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE 305 may use for a particular set of subframes).

[0063] In a transmission mode in which resource selection and / or scheduling is performed by the UE 305, the UE 305 may generate a sidelink grant and may transmit the grant in the SCI 330. The sidelink grant may indicate, for example, one or more parameters (e.g., transmission parameters) to be used for an upcoming sidelink transmission, such as one or more resource blocks (e.g., for TB 335) to be used for an upcoming sidelink transmission on the PSSCH 320, one or more subframes to be used for an upcoming sidelink transmission, and / or an MCS to be used for an upcoming sidelink transmission. In some aspects, the UE 305 may generate a sidelink grant that indicates one or more parameters (such as the periodicity of the sidelink transmission) for semi-persistent scheduling (SPS). Additionally or alternatively, the UE 305 may generate a sidelink grant for event-driven scheduling (such as for an on-demand sidelink message).

[0064] As indicated above, Figure 3 are provided as examples. Other examples can be found in Figure 3The content described is different.

[0065] Figure 4 is a diagram illustrating an example 400 of side link communications and access link communications according to the present disclosure.

[0066] 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 in conjunction with Figure 3 As further shown in the figure, in some sidelink modes, the base station 110 can communicate with the Tx / Rx UE 405 via the first access link. Additionally or alternatively, in some sidelink modes, the base station 110 can communicate with the Rx / Tx UE 410 via the second access link. The Tx / Rx UE 405 and / or the Rx / Tx UE 410 may correspond to one or more UEs described elsewhere herein, such as Figure 1 120. Thus, a direct link between UEs 120 (e.g., via a PC5 interface) may be referred to as a side link, and a direct link between base station 110 and UE 120 (e.g., via a Uu interface) may be referred to as an access link. Side link communications may be sent via a side link, and access link communications may be sent via an access link. Access link communications may be downlink communications (from base station 110 to UE 120) or uplink communications (from UE 120 to base station 110).

[0067] As indicated above, Figure 4 are provided as examples. Other examples can be found in Figure 4 The content described is different.

[0068] Figure 5 is a diagram illustrating an example 500 of a joint communication and radar sensing (JCR) system according to the present disclosure. Figure 5 As shown, a UE (e.g., UE 505) may communicate with one or more other UEs (e.g., UE 510) via a side link.

[0069] UEs such as UE 505 may use radio frequency (RF) sensing (e.g., radar sensing) for environmental sensing (e.g., to detect targets). For example, in an automotive deployment, a UE associated with a vehicle may transmit one or more sensing transmissions (also referred to as radar transmissions) and measure one or more reflections (e.g., reflections of the sensing transmissions off a target) to determine the distance of a target, the speed of a target, the direction of a target, or the acceleration of a target, etc. Reserving dedicated RF resources for radar sensing may result in inefficient use of RF resources. For example, in a situation where a small number of UEs are performing RF sensing, some RF resources may not be used while communication resources are congested with transmissions from many UEs.

[0070] Thus, some communication systems may integrate wireless communication with RF sensing using a single pool of resources for both data transmission and sensing transmission. In this case, rather than having a first set of resources dedicated to radar sensing and a second set of resources dedicated to communication, a single set of resources is allocated for both communication and radar sensing. For example, some techniques may use 3GPP (e.g., NR) waveforms for both communication and radar sensing, thereby enabling a 3GPP device (e.g., UE, base station, roadside unit (RSU), CU, DU, RU, network node, or network entity, etc.) to use a receive processor (such as Figure 2 A configuration in which both communication and radar sensing are enabled for a single set of resources may be referred to as a "joint communication and radar sensing" or "joint communication and radar" ("JCR") deployment.

[0071] like Figure 5 , a portion of a side link resource pool is shown, wherein data transmission and sensing transmission occur on orthogonal side link resources within the side link resource pool. As used herein, transmissions may originate from the same UE (e.g., UE 505), from different UEs, or a combination thereof. As shown, sensing transmissions typically have a relatively large bandwidth utilization (e.g., relative to data transmissions), occupy many or all available subchannels and / or side link resources, and typically span more than one time slot.

[0072] As indicated above, Figure 5 are provided as examples. Other examples can be found in Figure 5 The content described is different.

[0073] Multiple UEs and vehicles using the same side link resource pool for both data transmission and sensing transmission may result in a significant increase in the side link network load. In the mode 2 side link, conflicts and interference between transmissions from multiple UEs may be difficult to avoid without network entity scheduling to ensure orthogonality of transmission. Congestion control can use channel busy rate (CBR) and channel occupancy rate (CR) to facilitate avoiding conflicts and interference. For example, the UE can measure the RSSI of the transmission over a preconfigured sensing window to determine the percentage of resources being used by all UEs within the range. Using the CR that measures the congestion caused by the UE itself, the UE can adjust the transmission parameters (e.g., MCS, the number of subchannels, the number of side link resources, the number of retransmissions, etc.) to ensure that the CR does not exceed a preconfigured threshold (e.g., depending on the threshold of the measured CBR). Although congestion control can enable the UE to avoid some conflicts and interference, treating data and sensing transmissions equally can result in overly aggressive data throughput reductions, and treating sensing transmissions as additional features or services can reduce the priority of sensing transmissions that may be required for security features (such as conflict avoidance). Therefore, a congested resource pool that does not differentiate between CBR measurements and / or CR calculations for data and sensing transmissions may result in incorrect prioritization of data transmissions and / or sensing transmissions.

[0074] Some techniques and apparatus described herein enable a UE to control congestion in a mode 2 side link in a manner that distinguishes between data transmissions and sensing transmissions. For example, the UE may determine a first CBR associated with the data transmission, a second CBR associated with the sensing transmission, and transmit communications based at least in part on the first CBR and the second CBR. Thus, the UE may use separate CR thresholds for the UE's data transmissions and sensing transmissions, which enables the UE to apply different congestion controls between different types of transmissions when performing congestion control (e.g., transmitting different types of communications with different parameters). In this way, the UE may improve the UE's ability to reduce conflicts and interference between transmissions relative to congestion control that does not distinguish between transmission types, while also facilitating the use of a side link resource pool by prioritizing and managing QoS for data transmissions and / or sensing transmissions separately. For example, by using different CBR measurements, CR calculations, and / or CR thresholds, a UE using a side link resource pool may resolve conflicts and interference by prioritizing data and / or sensing transmissions differently.

[0075] Figure 6 is a diagram illustrating an example 600 associated with sidelink congestion control for sensing and data transmission according to the present disclosure. Figure 6As shown, a UE (e.g., UE 120-1) and other UEs (e.g., UE 120-2, UE 120-3, UE 120-4, and UE 120-5) can communicate with each other. For example, the UEs can communicate with each other via a side link using a shared side link resource pool. In some aspects, the UEs can send data transmissions and / or sensing transmissions.

[0076] As indicated by reference numeral 605, a UE (e.g., UE 120-1) may determine a first CBR associated with a data transmission (e.g., a communication transmission, not a sensing / radar transmission) detected within a first time period. In some aspects, the first CBR is based at least in part on a portion of the sidelink resources in a sidelink resource pool used for data transmission and a signal strength measurement that satisfies a first signal strength threshold (e.g., a preconfigured RSSI threshold for data transmission). For example, the first CBR may be measured at time slot n and defined as a portion of the sidelink resources in the sidelink resource pool used for data transmission (e.g., sidelink transmissions, such as V2X transmissions) over a CBR measurement window and having an RSSI measured by the UE that satisfies a threshold (e.g., a preconfigured RSSI threshold). The CBR measurement window may be, for example, from na to n-1, where a may be a preconfigured time period (e.g., a may be the number of time slots according to a higher layer parameter such as a timeWindowSize-CBR parameter).

[0077] For example, when a first time period (eg, CBR measurement window) includes 1,000 side link resources and 300 are used for data transmission whose RSSI meets a first signal strength threshold, the UE may determine that the first CBR is 0.3 (eg, 300 / 1,000=0.3).

[0078] In some aspects, the UE may identify a data transmission based at least in part on the data transmission satisfying a data CBR signal strength threshold (e.g., a preconfigured RSSI threshold) and / or the data transmission having one or more data-specific characteristics. In some aspects, the data-specific characteristics may include an SCI indicating a data transmission; a data transmission having a corresponding time slot, wherein the last symbol of the corresponding time slot is empty, and the like. For example, if the UE is able to decode the SCI for the transmission, the UE may determine that the transmission is a data transmission (e.g., the ability to decode alone may indicate a data transmission, and / or an explicit indication in the decoded SCI may indicate a data transmission). As another example, if the last symbol of the sidelink resource is identified as empty (e.g., a gap symbol, or a low energy symbol that does not meet a preconfigured threshold energy level), this may indicate a data transmission caused by the gap symbol being used to facilitate a subsequent time slot to transition from a transmit mode to a receive mode. In some aspects, a transmission may default to being considered a data transmission only by satisfying a data CBR signal strength threshold. The UE may use any combination of the foregoing criteria for identifying a transmission as a data transmission.

[0079] As indicated by reference numeral 610, the UE may determine a second CBR associated with a sensing transmission (e.g., a radar transmission, not a data / communication transmission) detected over a second time period that at least partially overlaps the first time period. In some aspects, the second CBR is based at least in part on a portion of the side link resources in the side link resource pool used for the sensing transmission and a signal strength measurement that satisfies a second signal strength threshold (e.g., a preconfigured RSSI threshold for the sensing transmission). The UE may measure the second CBR in a manner similar to that of the first CBR, as described herein. For example, the second CBR may be measured at time slot n and is defined as a portion of the side link resources in the side link resource pool used for sensing transmission (e.g., radar transmission) over the CBR measurement window and having an RSSI measured by the UE that satisfies a threshold (e.g., a preconfigured RSSI threshold). The CBR measurement window may be configured to be the same or different from other CBR measurement windows described herein, and may be configured in a manner similar to that described herein.

[0080] For example, when the second time period (eg, CBR measurement window) includes 1,000 side link resources and 500 are used for sensing transmissions whose RSSI meets the second signal strength threshold, the UE may determine that the second CBR is 0.5 (eg, 500 / 1,000=0.5).

[0081] In some aspects, the UE may identify a sensing transmission based at least in part on the sensing transmission satisfying a sensing CBR signal strength threshold (e.g., a preconfigured RSSI threshold) and / or the sensing transmission having one or more sensing specific characteristics. In some aspects, the sensing specific characteristics may include an SCI indicating a sensing transmission; the sensing transmission includes a preconfigured sequence identifying the sensing transmission; the sensing transmission has a corresponding time slot, wherein the last symbol of the corresponding time slot is not empty, and the like. For example, the SCI may include a field that explicitly indicates that the corresponding transmission is a sensing transmission (e.g., a 1-bit field in SCI-1 or SCI-2). As another example, the SCI may include a field whose value is set to an invalid value to indicate that the corresponding transmission is a sensing transmission (e.g., setting the MCS field to an invalid MCS value). In addition, the preconfigured sequence of the sensing transmission may include, for example, at least one preconfigured sequence (e.g., unique and / or from a specific sequence set). The preconfigured sequence may be defined on a symbol set (e.g., in the frequency domain) and / or directly in the time domain. As another example, if the last symbol of a transmission in a sidelink resource (e.g., a time slot) is identified as non-empty (e.g., a high energy symbol that meets a preconfigured threshold energy level), this may indicate a sensing transmission because gap symbols are used in data transmissions and the high energy indicates that gap symbols are not present. Although in some cases a gap symbol may be used in the last time slot of a sensing transmission, as part of the sensing transmission, the UE may identify sidelink resources in a time slot following a time slot in which the last symbol is not a gap symbol.

[0082] In some aspects, the UE may use any combination of the foregoing criteria for identifying a transmission as a sensing transmission.

[0083] In some aspects, the UE may determine a third CBR associated with a transmission detected over a third time period that at least partially overlaps with the first time period (e.g., all transmissions that meet a specific criterion, which may include both digital transmissions and sensing transmissions). In some aspects, the third CBR is based at least in part on a portion of the sidelink resources in the sidelink resource pool for any transmission that meets a third signal strength threshold (e.g., a preconfigured RSSI threshold for transmissions to be included in the CBR calculation). The UE may measure the third CBR in a manner similar to that of the first CBR and the second CBR, as described herein. For example, the third CBR may be measured at time slot n and is defined as a portion of the sidelink resources in the sidelink resource pool for any transmission (e.g., data / communication transmissions, sensing / radar transmissions, or other transmissions) over the CBR measurement window and having an RSSI measured by the UE that meets a threshold (e.g., a preconfigured RSSI threshold). The CBR measurement window may be configured to be the same or different from other CBR measurement windows described herein, and may be configured in a manner similar to that described herein.

[0084] For example, where a third time period (e.g., CBR measurement window) includes 1,000 side link resources and 900 are used for transmissions whose RSSI meets a third signal strength threshold, the UE may determine that the third CBR is 0.9 (e.g., 900 / 1,000=0.9). In this case, given the aforementioned example values ​​of the first CBR (e.g., 0.3) and the second CBR (e.g., 0.5), the UE may determine that some (e.g., 100) of the transmissions counted in the third CBR are neither data transmissions nor sensing transmissions. For example, this may occur when the third signal strength threshold is lower than a first signal strength threshold associated with the first CBR and lower than a second signal strength threshold associated with the second CBR.

[0085] In some aspects, the UE may identify a transmission as a joint data and sensing communication. For example, one transmission in a single side link resource may carry data and also be used as a sounding signal to simultaneously perform sensing. These joint data and sensing transmissions (because they carry data) may be detected as data transmissions. Thus, in some aspects, the joint data and sensing transmissions may contribute only to the first CBR for data transmissions.

[0086] Although the first CBR, the second CBR, and the third CBR are referred to as "first," "second," and "third," this should not be construed as limiting the order in which they are determined or used. Any of the three CBRs (including any combination of CBRs) can be used to determine the transmission parameters, as further described herein.

[0087] As indicated by reference numeral 615, the UE may determine a CR threshold for communication. For example, the UE may use the CR threshold to determine transmit parameters for communication in a manner designed to ensure that the UE's CR does not exceed the CR threshold, which may reflect congestion caused by the UE to the network (e.g., the sidelink network).

[0088] In some aspects, the UE may determine the CR for data communications separately from the CR for sensing communications and / or the CR for all communications. For example, the sidelink data CR evaluated at time slot n may be defined as the total number of sidelink resources used for data transmissions of UEs in time slots na to n-1, granted for data transmissions of UEs in time slots n to n+b, and divided by the total number of configured sidelink resources in the sidelink resource pool on na to n+b. The sidelink sensing CR evaluated at time slot n may be defined as the total number of sidelink resources used for sensing transmissions of UEs in time slots na to n-1 and granted for sensing transmissions of UEs in time slots n to n+b, divided by the total number of configured sidelink resources in the sidelink resource pool on na to n+b. An inclusive CR including transmissions of all UEs may be determined in a similar manner.

[0089] For example, the UE may determine the CR at time slot n as follows: N for sensing transmission in time slot [na, n-1] r,1 sidelink resources and N granted for sensing transmission in time slot [n,n+b] r,2 sidelink resources, and N for data transmission in time slot [na,n-1] d,2 sidelink resources and N granted for data transmission in [n,n+b] d,2 Sidelink resources can result in:

[0090] (1)

[0091] (2)

[0092] (3)

[0093] N tot is the total number of subchannels included in time slot [na,n+b]. Although at least some of the variables n, a, and b are used in the aforementioned formulas to calculate one or more CBRs and / or CRs, these variables may be independent. For example, the variables may have different values ​​(or the same value) for different CBR / CR calculations (e.g., the value of a for the first CBR may be different from the value of a for the data CR).

[0094] In some aspects, the communication to be sent by the UE may be a joint data and sensing communication. For example, one transmission in a single side link resource may carry data and also be used as a sounding signal to perform sensing at the same time. In some aspects, the joint data and sensing transmissions (because they carry data) may be considered as data transmissions. Therefore, in some aspects, the joint data and sensing transmissions may contribute only to the data CR. In some aspects, because they are used as sounding signals, the joint data and sensing transmissions may be considered as sensing transmissions and contribute only to the sensing CR. In some aspects, the joint data and sensing transmissions may contribute to both the data CR and the sensing CR. For example, a first preconfigured portion (e.g., a preconfigured percentage) of the side link resources for the joint data and sensing transmissions may be counted for the data CR, while a second preconfigured portion (e.g., another preconfigured percentage) of the side link resources for the joint data and sensing transmissions may be counted for the sensing CR. As an example, 60% of the joint data and sensing transmissions may be considered as data transmissions counted toward the data CR, and the remaining 40% of the joint data and sensing transmissions may be considered as sensing transmissions counted toward the sensing CR.

[0095] In some aspects, the UE may determine a first CR threshold for the communication based at least in part on the first CBR. For example, if the communication is a data transmission, the first CR threshold may be a CR threshold specifically for data transmission. In some aspects, the UE may determine the first CR threshold based at least in part on a mapping of the first CBR to the first CR threshold. For example, for any given first CBR value, there may be a corresponding first CR threshold. In some aspects, the first CBR value may be mapped to multiple thresholds (e.g., separate thresholds for different transmission priorities).

[0096] In some aspects, the UE may determine a second CR threshold for the communication based at least in part on the second CBR. For example, if the communication is a sensing transmission, the second CR threshold may be a CR threshold specifically for sensing transmission. In some aspects, the UE may determine the second CR threshold based at least in part on a mapping of the second CBR to the second CR threshold. For example, for any given second CBR value, there may be a corresponding second CR threshold. In some aspects, the second CBR value may be mapped to multiple thresholds (e.g., separate thresholds for different transmission priorities).

[0097] In some aspects, the UE may determine a third CR threshold for the communication based at least in part on the third CBR. For example, the third CR threshold may be a CR threshold that can be used for both data transmission and sensing transmission (e.g., an inclusive CR threshold). In some aspects, the UE may determine the third CR threshold based at least in part on a mapping of the third CBR to the third CR threshold. For example, for any given third CBR value, there may be a corresponding third CR threshold. In some aspects, the third CBR value may be mapped to multiple thresholds (e.g., separate thresholds for different transmission priorities).

[0098] In some aspects, the CR threshold may be selected based on one or more of the first CBR, the second CBR, and / or the third CBR. For example, any combination of CBR values ​​may be mapped to one or more CR thresholds for transmissions of different types and priorities. For example, for a given first CBR value, a second CBR value, and a third CBR value, the UE may be preconfigured with a mapping that identifies a set of CR thresholds based at least in part on the CBR value. The CR threshold set may include, for example, a data CR threshold for data transmission, a sensing CR threshold for sensing transmission, an inclusive CR threshold for any type of transmission, and / or a separate threshold for different priority communications of any of the aforementioned types. In this way, the UE can use the CR value of any type of transmission to compare with any mapped CR threshold (e.g., based on the CBR value) to determine the transmission parameters, as described herein.

[0099] As shown by reference numeral 620, the UE may send communications based at least in part on the first CBR and the second CBR. For example, the first CBR and the second CBR may be used to determine the CR threshold. In some aspects, the CR threshold used for sending may depend on the type of communication. For example, a data transmission may have a corresponding data CR threshold (e.g., a first threshold), and a sensing transmission may have a corresponding sensing CR threshold (e.g., a second threshold). As another example, an inclusive CR threshold may be used for any type of transmission (e.g., both data transmission and sensing transmission).

[0100] In some aspects, the UE may set and / or adjust one or more transmission parameters for communication based at least in part on the first CBR, the second CBR, and / or the third CBR. For example, the first CBR, the second CBR, and / or the third CBR may be used to determine one or more CR thresholds. Using the CR threshold, the UE may determine which transmission parameters to use to ensure that an upcoming transmission has a CR value that does not exceed the CR threshold. In some aspects, the transmission parameters may include the MCS, the number of subchannels, and / or the number of retransmissions to be used to transmit the communication.

[0101] For example, before sending a data transmission, the UE may determine a data CBR, a sensing CBR, and an inclusive CBR. The UE may map the three CBR values ​​to a CR threshold set, which may include a data CR threshold for the data transmission. Using the data CR threshold, the UE may select an MCS value (and other parameters) for the data transmission that will ensure that the data transmission does not exceed the data CR threshold. After selecting the MCS value, the UE may then send the data transmission.

[0102] In this way, the UE may use separate CR thresholds for the UE's data transmissions and sensing transmissions, which enables the UE to apply different congestion control between different types of transmissions when performing congestion control (e.g., transmitting different types of communications with different parameters). In this way, the UE may improve the UE's ability to reduce conflicts and interference between transmissions relative to congestion control that does not distinguish between transmission types, while also facilitating the use of the sidelink resource pool in a manner that prioritizes and manages QoS for data transmissions and / or sensing transmissions separately. For example, by using different CBR measurements, CR calculations, and / or CR thresholds, a UE using a sidelink resource pool may resolve conflicts and interference by prioritizing data and / or sensing transmissions differently.

[0103] As indicated above, Figure 6 are provided as examples. Other examples can be found in Figure 6 The content described is different.
