    Abstract: Disclosed are techniques for wireless communication, and specifically for reconfigurable intelligent surface (RIS)-aided positioning. In some aspects, a base station (BS) may transmit, to a user equipment (UE), a first positioning reference signal (PRS). The BS may transmit, to RIS configured to reflect a received signal towards the UE, a second PRS. The BS may receive, from the UE, a downlink reference signal time difference (RSTD) measurement for the first PRS and the second PRS.

    Abstract: An apparatus comprises: an interface; a memory; and a processor, communicatively coupled to the interface and the memory, configured to: instruct a node to send a first cellular reference signal to a target UE (user equipment) and to another UE, the node being a cellular-communication node; instruct, via the interface, the target UE to report to the node a first time difference, the first time difference being a first time amount between receipt of the first cellular reference signal by the target UE and transmission of a second cellular reference signal by the target UE; and instruct, via the interface, the other UE to report a second time difference, the second time difference being a second time amount between receipt of the first cellular reference signal by the other UE and receipt of the second cellular reference signal, in a cross-link interference resource, by the other UE.

    Abstract: Aspects of the present disclosure are regarding cross-link interference (CLI) measurements for received signal strength indicator (RSSI) based positioning. An example method for wireless communication performed by a first user equipment (UE), comprising: receiving, from a base station, a first message comprising a cross-link interference (CLI) configuration; performing one or more CLI measurements associated with an uplink transmission of a second UE based on the CLI configuration; receiving a second message comprising an uplink transmission power measurement of the second UE; determining a pathloss associated with the second UE based on the one or more CLI measurements and the uplink transmission power measurement; and determining a range between a location of the first UE and a location of the second UE based on the pathloss.
