Abstract: Disclosed are techniques for wireless communication. In an aspect, a first network node obtains one or more first positioning measurements of one or more reference signals transmitted by one or more second network nodes during a positioning session between a user equipment (UE) and a location server, and obtains one or more second positioning measurements of one or more backscattered signals of the one or more reference signals during the positioning session, wherein the one or more backscattered signals are transmitted by one or more ambient radio frequency identification (RFID) devices.

Abstract: A method of wireless communication performed by a user equipment (UE) is disclosed and includes determining a position of the UE based on a first positioning synchronization source; pre-configuring a first sidelink coordination group for use by the UE prior to an occurrence of one or more first triggering events, wherein the first sidelink coordination group uses a second positioning synchronization source that is different than the first positioning synchronization source; and in response to a determination that the one or more first triggering events has occurred, transitioning to use of the first sidelink coordination group for determining the position of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support non-codebook-based precoding based on downlink channel predictions. A user equipment (UE) may receive control signaling indicating a channel state information (CSI) reference signal (CSI-RS) and a sounding reference signal (SRS) resource. The control signaling may instruct the UE to transmit an SRS via the SRS resource. The control signaling may indicate a differential value indicating a time after the SRS resource at which the UE is to predict CSI. The UE may receive, via the CSI-RS resource, a CSI-RS. The UE may transmit, via the SRS resource, the SRS that is precoded based on predicted CSI for a wireless channel resource that occurs in time after the SRS resource. The predicted CSI may be based on the CSI-RS.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) may obtain a configuration that defines a first number of positioning measurement transmission beams, each positioning measurement transmission beam associated with a boresight transmission angle of the UE, and a second number of positioning discovery transmission beams, each positioning discovery transmission beam associated with a boresight transmission angle of the UE. The UE may transmit the positioning discovery transmission beams, then receive, from at least one other UE, feedback related to at least one of the positioning discovery transmission beams, and, based on that feedback, determine a subset of the positioning measurement transmission beams to be used for performing positioning measurements. The UE may perform the positioning measurements using the subset of the positioning measurement transmission beams.

Abstract: Method and apparatus for optimizing the reporting of Uu-RTT or SL-RTT measurements. The apparatus determines a RX-RS-TX-RS proximity parameter defining a proximity window around the RX-RS resource for receiving the RX-RS. The apparatus identifies a TX-RS resource of at least one TX-RS resource for transmitting TX-RS within a proximity window around a RX-RS resource for receiving RX-RS. An identified TX-RS resource being used by the UE for determining a UE RX-TX time difference associated with a time difference between reception of the RX-RS and transmission of the TX-RS. The apparatus measures the UE RX-TX time difference based on received RX-RS in the RX-RS resource and transmitted TX-RS in the identified TX-RS resource when TX-RS is transmitted in the identified TX-RS resource.

Abstract: In an aspect, a user equipment (UE) may receive positioning assistance data from a location server, wherein the positioning assistance data identifies one or more first positioning reference signal (PRS) resources for measurement by the UE during a positioning session between the UE and a location server. The UE may receive post-measurement positioning assistance data from at least one sidelink device located within a threshold distance to the UE, wherein the post-measurement positioning assistance data received from the at least one sidelink device is based on measurements of one or more second PRS resources obtained by the at least one sidelink device during a positioning session of the at least one sidelink device. The UE may selectively measure at least a subset of the one or more first PRS resources based on the post-measurement positioning assistance data received from the at least one sidelink device.

Abstract: Disclosed are techniques for wireless positioning performed by a user equipment. For example, the method includes entering into a Radio Resource Control (RRC) inactive state. The method includes monitoring, during a first time interval, while the user equipment is in the RRC inactive state, one or more first bandwidth parts having a first bandwidth to perform a first operation. The method includes monitoring, during a second time interval, while the user equipment is in the RRC inactive state, one or more second bandwidth parts having a second bandwidth to perform a second operation. The second bandwidth is different than the second bandwidth.

Abstract: Disclosed are techniques for positioning. In an aspect, a network entity receives, from a first base station of a user equipment (UE) operating in a radio resource control (RRC) inactive state, an event report message indicating that the UE has received a request to perform a positioning procedure, and transmits, based on a determination that the UE would benefit from updated positioning assistance data for the positioning procedure, the updated positioning assistance data to a second base station of the UE to enable the second base station to send the updated positioning assistance data to the UE.
