Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a sidelink resource sub-pool configuration that indicates a partition of a sidelink resource pool into a first sidelink resource sub-pool associated with radar transmissions and a second sidelink resource sub-pool associated with sidelink transmissions. The UE may transmit a radar transmission using resources of the first sidelink resource sub-pool based at least in part on the sidelink resource sub-pool configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may include a radar which is used for object detection, such as a vehicle UE detecting other vehicle UEs in a vehicle-to-everything (V2X) communications system. The UE may be configured for coordinated interference, where radars transmit a common waveform while applying different delays to prevent negative co-channel interference effects, such as false or ghost targets. The techniques described herein support configuring a common configuration for network-assisted coordinated interference by considering capabilities of UEs and radars within a geographic area controlled by a network entity. The network entity may identify and indicate a waveform configuration which is used by radars within the geographic control area of the network entity.

Abstract: Certain aspects of the present disclosure provide techniques for coordinating waveform parameters and frame delays for multi-radar coexistence. An example method performed by an apparatus comprising a radar device includes transmitting, based on a transmission configuration, one or more first signals of a plurality of signals in an environment via the radar device in a first frame of a plurality of frames according to a first delay value occurring after a frame prior to the first frame and transmitting one or more second signals via the radar device in at least a second frame of the plurality of frames according to a second delay value occurring after the first frame based on the transmission configuration. In some cases, the transmission configuration comprises a common transmission configuration for use in the environment. Additionally, in some cases, the second delay value is different from the first delay value.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for radar target tracking based on return signal strength. A wireless device, such as a radar device, may measure a received signal strength of a detected signal. The received signal strength may be associated with at least one bin of a radar image. The wireless device may compare the received signal strength to a filtered signal strength. The filtered signal strength may be associated with a threshold difference in signal strength from the filtered signal strength. The wireless device may track the at least one bin of the radar image in response to the received signal strength being less than or equal to the threshold difference in signal strength from the filtered signal strength.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, from one or more user equipments (UEs), feedback information associated with a distributed sensing procedure. The network node may select, based at least in part on the feedback information, a set of UEs to be included in the distributed sensing procedure. The network node may transmit, to the set of UEs, an indication of configuration parameters associated with the distributed sensing procedure. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a transmit diversity configuration for transmitting multiple sidelink messages. The UE may identify a transmit diversity configuration that indicates a set of component carriers (CCs) available for sidelink communication. The UE may transmit, based on the transmit diversity configuration, a first sidelink message having a first redundancy version (RV) of a transport block (TB), and a second sidelink message having a second RV of the TB, on multiple CCs. In a second case, the UE may identify a transmit diversity configuration indicating a set of precoding matrices. The UE may transmit the first sidelink message, including a TB or an RV of a TB, precoded using a first precoding matrix and a second sidelink message, including a TB or an RV of a TB, precoded using a second precoding matrix on multiple CCs.

Abstract: Wireless communications systems and methods related to channel occupancy time (COT) sharing for sidelink communications in unlicensed bands are provided. A method for wireless communication by a first user equipment (UE) may include measuring a first reference signal received power (RSRP) of a physical sidelink feedback channel (PSFCH) transmission transmitted during a channel occupancy time (COT) initiated by a second UE and accessing a first slot of the COT based on the first RSRP.
