Abstract: A mobile device and base station are enabled to support improved positioning accuracy in the presence of phase noise in high frequency radio network, such as in 5G New Radio network operating in mm Wave. Phase Tracking Reference Signal (PTRS) may be transmitted with Positioning Reference Signals (PRS) and used for positioning and/or used to correct the phase offset between symbols in the PRS (1302). A request may be made to transmit PTRS alone or with the PRS, or that the PRS is transmitted with a specific PRS frame structure, e.g., with a specific comb value, that minimizes the impact of phase noise. The PTRS or a phase ramp of the staggered symbols in the PRS may be used to estimate and correct the phase offset (1304, 1306).

Abstract: Aspects presented herein may enable a network entity to associate one or more positioning related parameters between a UE and an NTN base station with a scheduling offset, a position of the NTN base station, and/or a time. In one aspect, a network entity identifies a scheduling offset that is associated with an NTN base station. The network entity transmits, to a UE communicating with the NTN base station, one or more of: a set of expected RSTD values associated with the NTN base station, a set of compensation factors associated with the set of expected RSTD values, a set of uncertainty values associated with the set of expected RSTD values, a set of expected DL-AoD value s/uncertainties associated with the NTN base station, or a set of expected AoA value s/uncertainties associated with the NTN base station, where one or more of these parameters are derived based on the scheduling offset.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless node establishes sidelink connections with a set of UEs. The wireless node transmits, to a network component, a request for sidelink resources for a sidelink position estimation procedure associated with the set of UEs. The network component determines an available sidelink resource pool for the sidelink position estimation procedure in response to the request. The network component transmits, to the wireless node in response to the request, an indication of the available sidelink resource pool for the sidelink position estimation procedure. The wireless node transmits, to each UE in the set of UEs, a sidelink resource configuration that is based on the available sidelink resource pool for the sidelink position estimation procedure.

Abstract: A network node supports position measurement determination for a user equipment (UE) by prioritizing positioning reference signal (PRS) resource measurements to be included in a location information report based on multipath characteristics of the PRS resources. The network node, for example, may be the UE, a base station, or a sidelink UE. The PRS resource measurements may be prioritized by determining a subset of available PRS resource measurements to include in and/or the order of inclusion in the location information report. The multipath characteristics of each PRS resource may be the number, a strength metric, or a time domain span of the multipath components, or any combination thereof. A location server may request the prioritization of the PRS resource measurements based on the multipath characteristics of the PRS resources and may use the order of the PRS resource measurements in the position determination for the UE.
