Abstract: A network element estimates a position of a user equipment served by a first network and a second network. At the network element, at least one memory and computer program code are configured to, with at least one processor, cause the network element to: determine first position measurement information for the user equipment in the first network; obtain position assistance data associated with the second network, the position assistance data including at least second position measurement information for the user equipment in the second network; obtain frequency offset information and time offset information for transmissions in the first network and transmissions in the second network; and estimate a position of the user equipment based on the first position measurement information, the second position measurement information, the frequency offset information and the time offset information.

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.
