Abstract: Disclosed are techniques for identifying virtual anchors. In an aspect, a network entity obtains a set of data samples associated with a user equipment (UE), each data sample comprising a location of the UE and a set of multipath components (MPCs) obtained by the UE, and determines whether any MPCs in a subset of non-line-of-sight (NLOS) MPCs selected from at least one set of MPCs are associated with any previously identified virtual anchors in a database of found virtual anchors, wherein one or more first NLOS MPCs are removed from the set of data samples based on the one or more first NLOS MPCs being associated with a previously identified virtual anchor, and wherein one or more second NLOS MPCs are added to the database of found virtual anchors based on the one or more second NLOS MPCs not being associated with any previously identified virtual anchor.

Abstract: A method for wireless communication at a user equipment (UE), includes receiving, from any one transmit and receive point (TRP) of a group of TRPs, a first radio resource control (RRC) message configuring a linkage between a first physical downlink control channel (PDCCH) candidate associated with a first monitoring occasion in a first search space (SS) set associated with a first TRP of the group of TRPs and a second PDCCH candidate associated with a second monitoring occasion in a second SS set associated with a second TRP of the group of TRPs. The method also includes receiving, from any one TRP of the group of TRPs, a dynamic indication enabling or disabling the linkage. The method further includes monitoring the first monitoring occasion for first PDCCH candidate and selectively monitoring the second monitoring occasion for the second PDCCH candidate based on whether the linkage is enabled or disabled.

Abstract: In an aspect, a network entity may receive, from a target device, one or more self-radio frequency fingerprint (self-RFFP) measurements obtained by the target device based on reflections of one or more reference signals transmitted by the target device. The wireless device may determine a location of the target device based on applying a machine learning model to the one or more self-RFFP measurements.

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: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) maintains timing information for each of a plurality of beam pairs, each beam pair comprising a downlink (DL) beam pair, comprising a base station transmit beam and a UE receive beam or a sidelink (SL) beam pair, comprising a UE transmit beam and a UE receive beam. The UE measures a first reference signal using a first beam pair from the plurality of beam pairs, measures a second reference signal using a second beam pair from the plurality of beam pairs, and reports, to a transmitting entity, beam timings for the first beam pair and the second beam pair. The measuring steps, the reporting step, or both, are performed according to the timing information for the first beam pair and the second beam pair.
