Abstract: A network node may transmit an SSB indicating that the network may support physical layer security, and aUE may extract the secret key for the physical layer security based on the received SSB indicating that the network may support the physical layer security. The network node may indicate a level of the physical layer security using the SSB, and the UE may determine the level of the physical layer security based on the received SSB. In one aspect, the indication that the network may support the physical layer security may be included in the SSB. In another aspect, a synchronization raster of the SSB may indicate that the network supports the physical layer security.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive an announcement message from each sidelink anchor device of one or more sidelink anchor devices, wherein the announcement message includes a sidelink anchor device identifier and an indication that the sidelink anchor device is available for positioning services. The UE may measure the announcement message from each sidelink anchor device to determine a signal strength measurement associated with the sidelink anchor device. The UE may report, to a network node, one or more preferred sidelink anchor devices from the one or more sidelink anchor devices, wherein the one or more preferred sidelink anchor devices are determined based on the signal strength measurement respectively associated with each sidelink anchor device of the one or more sidelink anchor devices.

Abstract: Disclosed are techniques for communication. In an aspect, a first node determines equiphase contour information associated with an antenna of the first node at one or more carrier frequencies, and transmits an indication of the equiphase contour information to a second node. In another aspect, a device determines equiphase contour information associated with an antenna of a first node at one or more carrier frequencies, and corrects measurement information associated with a carrier phase-based position estimation session based at least in part on the equiphase contour information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may encode a sequence associated with an acknowledgement status using a symmetric key. The symmetric key may be determined using channel reciprocity at a physical layer or may be determined using a higher layer of the UE. Accordingly, the UE may transmit the sequence associated with the acknowledgement status. Numerous other aspects are described.

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.

Abstract: Aspects presented herein may enable a UE to prioritize PRS and different DL channels in an RRC-inactive/idle state. In one aspect, a UE receives one or more PRSs and at least one DL channel in a measurement period and during an RRC-inactive state or an RRC-idle state, the one or more PRSs occupying a range of symbols that do not overlap with the at least one DL channel in time. The UE selects at least some portion of the one or more PRSs or at least some portion of the at least one DL channel for processing based on whether the range of symbols is within a time threshold of the at least one DL channel. The UE processes, based on the selection, the at least some portion of the one or more PRSs or the at least some portion of the at least one DL channel.
