Abstract: A user equipment (UE) may obtain a first indication of a first measurement gap resource associated with a first time period. The UE may receive a set of position reference signals (PRSs) during a PRS occasion. A first portion of the PRS occasion may not overlap with any portion of the first time period. The UE may measure the set of PRSs at the first portion of the PRS occasion based on at least one of (i) the first measurement gap resource associated with the first time period, (ii) a second measurement gap resource associated with a second time period that overlaps with the first portion of the PRS occasion, or (iii) a positioning processing window (PPW) associated with a third time period that overlaps with the first portion of the PRS occasion.

Abstract: Systems and techniques are provided for performing Quasi-Zenith Satellite System (QZSS) signal acquisition. For example, an example of a method for performing QZSS signal acquisition includes obtaining a modulated message signal using a frequency band and generating, based on an estimated set of signal acquisition parameters associated with an acquired signal, an energy grid of correlation codes. A series of extracted data bytes can be generated for each respective hypothesis of a plurality of hypotheses, based on a location of a peak energy within the energy grid of correlation codes. A correct hypothesis out of the plurality of hypotheses can be determined, wherein the correct hypothesis is associated with a generated series of extracted data bytes that includes a pre-determined header preamble pattern. The modulated message signal can be decoded using an initial code phase associated with the correct hypothesis.

Abstract: In an aspect, a first wireless node receives, from at least one second wireless node, RS-Ps at a plurality of RS-P MOs of a same RS-P resource, wherein each RS-P MO is transmitted at a different time instance on the same bandwidth of a time interval. The first wireless node performs, for a set of measurement types, one or more measurements of the RS-Ps at each of the plurality of RS-P MOs, and transmits, to a position estimation entity, a measurement report comprising at least one first representative measurement value associated with the time interval for a first respective measurement type of the set of measurement types and a first indication of variance associated with the at least one first representative measurement value across at least part of the plurality of RS-P MOs. The position estimation entity determines a location estimate of a UE based on the measurement report.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a location server, a positioning reference signal (PRS) configuration for a downlink-and-uplink-based positioning session between the UE and the location server, waits, based on a determination that a sounding reference signal (SRS) configuration for the downlink-and-uplink-based positioning session has not been received from a serving base station of the UE, for reception of the SRS configuration from the serving base station until expiration of a timer, and determines, based on the expiration of the timer, whether the SRS configuration was received.

Abstract: Aspects presented herein may improve the efficiency, accuracy, and/or latency of a UE positioning procedure by enabling mobility analytics associated with a UE or a set of UEs to be exchanged between a location server and an NWDAF, either directly or via another network entity. In one aspect, a first network entity transmits a request for mobility data associated with a set of UEs, where the request for the mobility data is transmitted for a second network entity associated with mobility data analytics. The first network entity receives, based on the request, an indication of the mobility data associated with the set of UEs. The first network performs at least one location function for at least one UE in the set of UEs based on the indication of the mobility data.

Abstract: A mobile device supports positioning with positioning reference signals (PRS) on multiple beam by dividing the PRS processing into two separate modes, an acquisition mode and a tracking mode. In acquisition mode, the mobile device performs a fast scan of all of the beams from a base station transmitting PRS using less than the full set of resources for the PRS, i.e., less than the full bandwidth and/or less than the full number of repetitions of the PRS. The mobile device may select the best beams to use for positioning, e.g., based on signal strength metric. In tracking mode, the mobile device tracks the PRS from only the selected beams using the full set of resources for the PRS. The mobile device may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.
