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: 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: 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 channel occupancy time (COT) duration indication that indicates a first COT duration associated with a first channel occupancy initiated by the base station. The UE may initiate, during a time duration that is outside of the first COT duration and based at least in part on performing a listen-before-talk procedure, a second channel occupancy having a second COT duration. Numerous other aspects are described.

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: Methods, systems, and devices for wireless communications are described. In an example, a method includes a first node receiving a precision time protocol (PTP) message, identifying one or more timing domains to be supported by the first node based at least in part on the PTP message, and sending, to a second node of the wireless communication network, an indicator of the one or more timing domains to be supported by the first node. Another example at a node includes receiving, from additional nodes of the wireless communication network, indicators of one or more timing domains supported by the additional nodes, receiving a PTP message associated with a timing domain, and sending the PTP message to a subset of the additional nodes based at least in a part on the indicators of one or more timing domains supported by the additional nodes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may receive, from a user equipment (UE), a demodulation reference signal (DMRS) associated with a channel. The RU may perform a channel estimation associated with the channel using the DMRS to obtain channel estimation information. The RU may transmit, to a distributed unit (DU), information that is based at least in part on the channel estimation information. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an open radio access network (O-RAN) distributed unit (O-DU) may generate, at an O-DU application that executes on the O-DU, a first message that does not make use of an O-DU accelerator of the O-DU that is in-line with the O-DU application. The O-DU may transmit, from the O-DU application to an O-RAN radio unit (O-RU), the first message via a passthrough of the O-DU accelerator, wherein the first message does not make use of the O-DU accelerator based at least in part on a payload of the first message being transferred unchanged by the O-DU accelerator to the O-RU. Numerous other aspects are described.
