Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) measures one or more positioning reference signal (PRS) resources of at least one PRS instance, and processes the one or more PRS resources of the at least one PRS instance during a PRS processing gap, wherein the PRS processing gap comprises a period of time during which the UE prioritizes PRS processing over reception, processing, or both of other downlink signals and channels.

Abstract: A user equipment (UE) obtains assistance data for positioning from one or more sidelink connected UEs. Prior to sending the assistance data for positioning to the UE, the sidelink UE(s) revises the assistance data, e.g., by reprioritizing, reordering, or reducing the assistance data, or a combination thereof. By revising the assistance data the sidelink UE(s) provides the most pertinent assistance data to the UE, thereby increasing power savings for the UE. Where multiple sidelink UEs provide revised assistance data to the UE, the UE combines the revised assistance data, e.g., based on measurement information, range information, or priority of the sidelink UEs. If the UE has a connection to the location server, the UE obtains revised assistance data from sidelink UE(s) to avoid the need for an assistance data exchange with the location server during the positioning session, thereby improving latency.

Abstract: Motion detection services are performed in a wireless network (e.g., a cellular network) with reference to beamforming. Reference signals or other resources for motion detection based on RAdio Detection And Ranging (RADAR) are transmitted over one or more transmit beams or received over one or more receive beams. Any motion measured from reflections of the signals may be associated with one or more of the transmit or receive beams. A device configured to receive the reflections determines one or more motion measurements associated with one or more beams, and determines one or more motion state metrics associated with the one or more beams. The one or more motion state metrics are included in one or more motion state reports to a network entity (e.g., a radar server), which may be used for various operations in the wireless network.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may use partial frequency sounding with different frequency subhop patterns so that a portion (which may be referred to as a subhop) of configured sounding reference signal (SRS) resources (e.g., a hop) are sounded. In some cases, a UE may receive a control message from a network entity identifying the frequency subhop pattern. In some cases, the network entity may configure a UE to transmit repetitions of the SRS in a same hop across consecutive symbols to increase a probability that the transmissions are successfully received and decoded by the network entity. As such, the network entity may configure a repetition factor for the frequency subhop pattern. In some cases, the frequency subhop pattern may introduce a frequency overlap between subhops.
