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: Techniques for line-of-sight (LOS) probability map signaling are disclosed. The techniques can include receiving a positioning signal via a wireless link between the UE and a transmission/reception point (TRP) of a radio access network (RAN), identifying an LOS probability function associated with the wireless link based on LOS probability map information provided by a location management function (LMF) of a core network for the RAN, and generating an LOS probability estimate for the wireless link using the LOS probability function.

Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.

Abstract: Disclosed are techniques for training a machine learning model. In an aspect, a user equipment (UE) receives, from a network entity, one or more selection criteria for determining whether the UE is to participate in training the machine learning model, determines whether the UE satisfies the one or more selection criteria during a first period of time, and transmits, to the network entity, after a second period of time, updated parameters for the machine learning model, wherein the machine learning model is updated during the second period of time based on a determination that the UE satisfies the one or more selection criteria.

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.
