Original Abstract Submitted
disclosed are techniques for positioning. in an aspect, a positioning entity receives a report indicating an operation mode of a reconfigurable intelligent surface (ris) associated with at least one base station, receives a transmission-to-reception (tx-rx) time difference measurement for a network node involved in a round-trip-time (rtt) positioning session with a user equipment (ue), determines a reception-to-transmission (rx-tx) time difference measurement for the ue, the rx-tx time difference measurement representing a difference between a reception time at the ue of a downlink positioning reference signal from the ris and a transmission time from the ue of an uplink positioning reference signal towards the ris, and calculates a distance between the ue and the ris based, at least in part, on the tx-rx time difference measurement and the rx-tx time difference measurement.
