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 mmWave. 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. 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. Less than all of the symbols transmitted in the PRS may be used to generate positioning measurements to minimize the impact of phase noise.

Abstract: In an embodiment, a UE transmits an on-demand PRS request for PRS(s) on selected frequency-domain resource(s) (e.g., frequency layer, frequency band, CC, etc.). In another embodiment, a UE receives, from a network component (e.g., BS, core network component, LMF, location server, etc.), configuration of frequency-domain resources (e.g., frequency layer, frequency band, CC, etc.), wherein each frequency-domain resource configuration is associated with a bandwidth and SCS. The UE further receives, from the network component, configuration of PRS(s), wherein each PRS is associated with a single frequency-domain resource from the frequency-domain resources. The UE determines a single reference TRP for each of the frequency-domain resources, performs PRS measurements on the PRS(s), and determines positioning measurements at least based on the PRS measurements and the determined reference TRPs.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives assistance data for enabling the UE to estimate a location of the UE, the assistance data including a relative location of each of a plurality of transmission points, wherein the relative location is represented as a hierarchy of two or more levels of description, wherein a highest level of description is relative to a fixed reference point, receives, from each of at least a subset of the plurality of transmission points, at least one positioning reference signal, and estimates the location of the UE based on characteristics of reception of the at least one positioning reference signal from each of the subset of the plurality of transmission points and the two or more levels of description and the fixed reference point for each of the subset of the plurality of transmission points.

Abstract: Techniques are provided for utilizing network positioning protocols to perform a base station location and orientation computation procedure. An example method of determining an orientation of a base station antenna with a network server includes receiving measurement values from a base station based on uplink reference signals transmitted by a plurality of reference location devices, obtaining location information for the plurality of reference location devices, and determining the orientation of the base station antenna based on the measurement values and the location information.

Abstract: Methods, systems, and devices for transmit power control for positioning using non-serving cells are described. A user equipment (UE) may determine that an uplink reference signal may be associated with a positioning procedure. In some cases, the positioning procedure may include transmission, by the UE, of the reference signal to a non-serving cell, which may be farther away from the UE than a serving cell. The UE may determine an absence of a parameter associated with a transmit power for transmitting the reference signal. Based on the absence, the UE may determine the transmit power based on parameters received from a serving cell, based on configuration information, based on a message intercepted from the non-serving cell, or based on other considerations or information. In some cases, the UE may determine the transmit power such that the likelihood of the non-serving cell receiving the reference signal is increased.

Abstract: Disclosed are techniques for determining round-trip time (RTT) of a user equipment (UE). In an aspect, each gNodeB in a plurality of gNodeBs measure signaling data related to an uplink RTT reference signal received from the UE and the downlink RTT reference signal transmitted by each gNodeB. The signaling data comprises one of a processing delay between a time of arrival (TOA) of the uplink RTT reference signal and a time of transmission (TOT) of the downlink RTT reference signal or a total RTT between the TOT of the downlink RTT reference signal and the TOA of the uplink RTT reference signal. The signaling data is sent to a single entity, other than the UE, e.g., another gNodeB or a location server, where signaling data relevant to the UE is aggregated. The aggregated signaling data may be sent to the UE to determine the RTT for the UE or used by the location server to determine the RTT for the UE.
