Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) transmits, to a base station, a first message of a random access procedure, the first message indicating that the UE is a positioning-only UE, receives, from the base station, in response to transmission of the first message, a sounding reference signal (SRS) configuration for the UE, the SRS configuration indicating one or more time and frequency resources on which the UE is expected to transmit SRS for an uplink-only positioning session, and transmits the SRS on the one or more time and frequency resources based on the SRS configuration.

Abstract: Embodiments described herein provide for an RIS-aided determination of the location of mobile device that enables the signal reflected by the RIS to be identified through channel estimation. More specifically, an Orthogonal Cover Code (OCC)-based approach may be taken where the RIS is configured to use different weights to reflect different reference signals, enabling a receiving device to identify the reflected signal. This can be utilized on signals used for positioning of the mobile device. Additionally or alternatively, this can be used for positioning of the RIS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may obtain, at an access stratum (AS) layer, an indication of an inter-satellite link (ISL) activation that is to take place at an activation time. The wireless communication device may receive communications. The wireless communication device may buffer the communications in a buffer at the AS layer. The wireless communication device may release the communications from the buffer to an upper protocol layer at a rate of release that is to change between a transition start time and the activation time. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a method for reconfigurable intelligent surface (RIS)-assisted sensing performed by a base station (BS) includes configuring one or more reciprocal RIS beam pairs for sensing, wherein each of the one or more reciprocal RIS beam pairs comprises a downlink (DL) beam having a DL angle of departure (DL AoD) from a RIS controlled by a first set of control voltages and an uplink (UL) beam having an UL AoD from the RIS controlled by a second set of control voltages. The BS may send, to the RIS, information identifying the one or more reciprocal RIS beam pairs. The BS may perform monostatic sensing using at least one of the one or more reciprocal RIS beam pairs.
