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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an uplink message (e.g., a scheduling request) indicating one or more beam directions (e.g., one beam direction, a set of beam directions, a sequence of beam directions), one or more beamwidths (e.g., for the one or more indicated beam directions), an angular area of interest for radar sensing, or a combination thereof. The network entity may then provide, to the UE, a grant of resources for performing the radar sensing on specific radar sensing transmit beams (e.g., that will not interfere with other radar sensing by other UEs, uplink communications form other UEs, sidelink communications by other UEs, etc.). The UE may indicate the directions of the beams with reference to a global coordinate system. The network may configure the UE with lookup tables (LUTs) defining relationships between indices, beam directions and/or beamwidths.

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: A user equipment (UE) and related techniques are disclosed. In one aspect, the UE provides, to one or more wireless nodes of a radio access network (NG-RAN) associated with the core network or a second network entity of the core network different from the first entity, an indication of sensing directions for transmitting and receiving a radar signal to sense an environment of the apparatus. Latency may be reduced for tracking targets by skipping exhaustive scanning or complex full processing by exploiting prior sensing measurement reports collected by a sensing management function (SnMF). In this way, interference may be reduced and less resource and power usage may be enabled for sensing functions. In one case, sensing directions can be indicated in GCS and translated to a respective sensors' beam direction in LCS at NG-RAN or UE for efficient beam management. In one case, SnMF indicates a sensing direction in LCS to NG-RAN or UE for sensing signal transmission and/or reception.
