Abstract: In an aspect, a UE receives a set of tracking reference signal (TRS) configurations associated with a respective set of cells, and performs a set of spatial measurements associated with a set of TRSs on resources configured by the respective set of TRS configurations. In a further aspect, a cell (e.g., a serving cell of the UE or a non-serving cell of the UE) determines a TRS configuration, and transmits, to the UE in association with a spatial measurement procedure, a TRS on at least one resource configured by the TRS configuration.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, a positioning reference signal (PRS) configuration indicating a pattern of PRS resources transmitted by at least one network node, and transmits a proposed measurement gap pattern to a serving network node, the proposed measurement gap pattern enabling the UE to measure at least a subset of PRS resources transmitted by each of the at least one network node, the proposed measurement gap pattern determined based on the pattern of PRS resources.

Abstract: Aspects presented herein may enable an ML module to associate RF fingerprints with beam directions and/or beam features to improve the uniqueness of RF fingerprints. In one aspect, network entity may receive, from one or more wireless devices, a plurality of first RF fingerprints, each of the plurality of first RF fingerprints being associated with at least one directional feature and a location. The network entity may receive a request to determine a position of a UE based on at least one second RF fingerprint associated with the UE or captured by the UE. The network entity may estimate the position of the UE based at least in part on matching the at least one second RF fingerprint to at least one of the plurality of first RF fingerprints.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a sounding reference signal (SRS) resource configuration, the SRS resource configuration indicating at least a comb pattern for at least one SRS resource allocated to the UE and a puncturing unit for the comb pattern, wherein the comb pattern is divided into one or more puncturing units, wherein each puncturing unit comprises one or more time units of the comb pattern, and wherein each of the one or more time units comprises two or more symbols, and refrains from transmitting all SRS transmissions of the at least one SRS resource within a first puncturing unit of the one or more puncturing units based on a determination that one or more SRS transmissions of the at least one SRS resource within the first puncturing unit are to be dropped.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a first radio resource control (RRC) configuration message that is associated with a first subband and that indicates a first set of transmission configuration indicator (TCI) states for use on the first subband. The UE may further receive, from the base station, a second RRC configuration message that is associated with a second subband included in the wideband channel and that indicates a second set of TCI states for use on the second subband. As an alternative, the UE may receive, from the base station, an RRC configuration message that includes at least a first list of first TCI states associated with a first subband and a second list of second TCI states associated with a second subband. Numerous other aspects are described.
