Abstract: A first apparatus is provided that is configured to receive, from a wireless device, an indication enabling radar measurement sharing; receive a first set of configuration parameters for the radar measurement sharing; perform a radar measurement based on the first set of configuration parameters and network state information; and transmit a first set of radar measurement transmissions at a first radar measurement transmission rate selected based on the first set of configuration parameters and the network state information. In some aspects, a second apparatus is provided that is configured to select a first set of UEs from a plurality of UEs for radar measurement sharing; transmit, to each UE in the first set of UEs, an indication enabling the radar measurement sharing; and receive, from each UE in the first set of UEs, a radar measurement transmission based on a radar measurement performed at a corresponding UE.

Abstract: Aspects relate to techniques for communication between wireless communication devices using ranging channel information obtained by each of the wireless communication devices. For example, a first wireless communication device may obtain first monostatic ranging channel information based on reflected ranging signals received in response to transmission of a ranging signal. In addition, the first wireless communication device may receive ranging feedback information from a second wireless communication device associated with second monostatic ranging channel information obtained by the second wireless communication device. The first wireless communication device may then determine bistatic channel information from the first monostatic ranging channel information and the ranging feedback information and transmit a message to the second wireless communication device based on the bistatic channel information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may transmit an orthogonal frequency division multiplexing (OFDM) signal on K subsets of N subcarriers, where the signal includes a sequence of modulated symbols for each subset of the K subsets that is distinct for each subset. The wireless device may receive a reflected OFDM signal that corresponds to the OFDM signal. The wireless device may process the reflected OFD.M signal with K mixers, where mixer frequencies for the K mixers are separated by N subcarriers spacing, to form K portions of a range spectrum from the reflected OFDM signal. The wireless device may combine the K portions to form the range spectrum. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit a discovery message to discover another UE with which to establish a cooperative radar sensing session. The first UE may receive, from a second UE, a join request for the first UE to establish the cooperative radar sensing session with the second CE, The first UE may transmit, to the second UE, an acceptance indication based at least in part on the join request. The first UE may communicate with the second UE to establish a joint configuration to be used by the first UE and the second UE for the cooperative radar sensing session, Numerous other aspects are described.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for sidelink resource selection with AD usage awareness. A UE may receive, from one or more ANs, one or more resource usage schedules associated with one or more ADs in communication with the one or more ANs. The UE may combine the one or more resource usage schedules associated with the one or more ADs into a combined resource usage schedule. The usages may be associated with the combined resource usage schedule, which may be indicative of excluded resources for a transmission of the UE. The UE may transmit, based on the combined resource usage schedule, the transmission of the UE on a resource other than the excluded resources.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a radar device. The radar device determines a resource pool configuration indicating a radar band partitioned into a plurality of non-overlapping subbands. At least two of the plurality of non-overlapping subbands use resource elements (REs) that differ in at least one of a frequency size or a time duration. The radar device transmits a radar waveform using at least one RE within a subband of the plurality of non-overlapping subbands.

Abstract: Aspects presented herein may enable a first UE to utilize inference results provided by at least a second UE to improve its inference accuracy. In one aspect, a first UE establishes an ML inference result sharing session with one or more second UEs for at least one ML inference task. The first UE receives a first set of ML inference results associated with the at least one ML inference task, where the first set of ML inference results is received from the one or more second UEs during the ML inference result sharing session. The first UE estimates an aggregated ML inference result based on at least one of the first set of ML inference results or a second set of ML inference results, where the second set of ML inference results is configured by the first UE for the at least one ML inference task.

Abstract: A method of wireless communication by a first user equipment (UE) includes requesting multi-static channel sensing estimates from a device to establish a communications link with a second UE, and receiving the multi-static channel sensing estimates from the device. The method further includes setting communication parameters based on the multi-static channel sensing estimates. The method still further includes communicating with the second UE over the communications link based on the communication parameters.
