Abstract
Methods, apparatuses, and computer programs are provided for SRS for positioning resource overhead reduction in multi-RTT. A method for a UE includes receiving an initial configuration of a plurality of sounding reference signal for positioning resources; measuring a downlink positioning reference signal received from one or more cells; determining one or more transmission beams based on reception beams used for receipt of the downlink positioning reference signal from the one or more cells; wherein the determining of the one or more transmission beams comprises a reduction of at least one beam resource associated with a sounding reference signal for positioning; and transmitting an updated sounding reference signal for positioning configuration with information about the determined one or more transmission beams. Methods are also provided for a radio node and for an LMF.
