Abstract: Systems, methods, apparatuses, and computer program products for positioning support are provided. One method may include receiving, by a UE configured with power saving feature(s), positioning performance requirements for a positioning session. The method may also include estimating an impact of one or more power saving or reduced capability features on positioning measurements associated with the positioning session and, based on the accuracy and latency requirements and the estimated impact, determining the power saving or reduced capability features that the UE can implement while still achieving the accuracy and latency requirements for the positioning session. The method may then include signaling, to a network node, information on the determined power saving or reduced capability features that the UE can implement while still achieving the required accuracy and latency requirements for the positioning session.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of retransmission of sidelink positioning reference signal (PRS). The method comprises transmitting, to a second device, a first sidelink reference signal associated with a positioning or ranging procedure of the first device; and receiving, from the second device, a second sidelink reference signal associated with the positioning or ranging procedure, the second sidelink reference signal comprising information indicating whether the first sidelink reference signal needs to be retransmitted. In this way, the retransmission of the sidelink PRS can be triggered without extra resource consumption and a fast RTT estimation for sidelink ranging and positioning can be achieved.

Abstract: Systems, methods, apparatuses, and computer program products for dynamic antenna array angular phase deviation compensation for broad beam positioning. For example, certain embodiments may provide for multi-round trip time (multi-RTT) positioning where a user equipment (UE) may report time of departure (TOD) compensation values to a serving gNB and/or location management function (LMF). The LMF may calibrate the RTT computation with the received TOD compensation values. As another example, certain embodiments may provide for uplink time difference of arrival (UL-TDOA) positioning where an LMF may signal calculated assistance information to the UE to request time of departure TOD compensation values. The UE may report the TOD compensation values to a location management function (LMF), and the LMF may compensate initial relative time of arrival (RTOA) estimates using the TOD compensation values.
