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.

Abstract: Aspects presented herein may improve joint communication-radar system by providing a radar reference signal with GI-FMCW waveform. Aspects presented herein may be compatible with communication-centric waveforms and thereby may apply to UEs or network entities with minimal changes if specified. In one aspect, a wireless device transmits a set of communication signals. The wireless device configure one or more parameters associated with a set of radar reference signals for radar sensing based on the set of communication signals, each radar reference signal in the set of radar reference signals including a guard interval. The wireless device transmits the set of radar reference signals associated with the one or more parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information identifying a shared channel occupancy for a packet transmission resource and a hop counter value associated with the shared channel occupancy. The user equipment may determine whether to transmit one or more packets in the shared channel occupancy based at least in part on the hop counter value associated with the shared channel occupancy. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit the sidelink message to a second UE via a sidelink communications channel of an unlicensed radio frequency spectrum band. The first UE or the second UE may transmit a reservation signal to retain the sidelink communication channel for corresponding feedback for the sidelink message (e.g., while the second UE generates a feedback transmission). The second UE may transmit the feedback transmission over the sidelink communication channel.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for channel selection in systems that utilize both licensed and unlicensed frequency bands. As will be described in greater detail below, user equipments (UEs) that share unlicensed frequency band may select a channel in an unlicensed frequency band and advertise their channel selection over a licensed frequency band, in an effort to coordinate communications other UEs. An example method may include selecting at least a first channel within an unlicensed band for communications with at least a second UE, and transmitting, on a licensed band, an indication of the first channel and location information for the selection.
