Abstract: Disclosed are techniques for wireless positioning. In an aspect, a network entity, such as a location server, may determine information characterizing a channel associated with a wireless device within a region of interest. The network entity may determine a location of the wireless device within the region of interest based on that information and a set of radio frequency fingerprints (RFFPs), where each RFFP identifies a geographic location within a region of interest and a channel condition at that geographic location within the region of interest, and where each geographic location within the region of interest is represented by a set of RFFPs having different channel conditions due to different states of at least one reconfigurable intelligent surface (RIS) within the region of interest.

Abstract: Wireless communications systems and methods related to channel congestion estimations based on virtual collision metrics are provided. A user equipment (UE) may select a plurality of resources from a sidelink resource pool. The UE may request an evaluation of an availability of the plurality of resources and may receive an indication of the availability of the plurality of resources. The UE may further transmit, based on a virtual collision metric associated with the indication of the availability of the plurality of resources, a first sidelink transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a logical channel prioritization (LCP) restriction configuration for a logical channel indicating one or more control resource set (CORESET) pool index values associated with the logical channel. The UE may receive an uplink grant for transmission of an uplink communication, the uplink grant being associated with a CORESET pool index value of the one or more CORESET pool index values. The UE may select the logical channel to use resources of the uplink grant for transmission of the uplink communication based at least in part on the CORESET pool index value and the LCP restriction configuration. Numerous other aspects are provided.

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: In an embodiment, a wireless node (e.g., UE or BS) receives from a network component (e.g., BS or core network component) a request for a positioning estimate of a UE associated with a specified time. The wireless node performs positioning measurements at a plurality of times, and determines (e.g., via interpolation or extrapolation) the positioning estimate associated with the specified time based on the positioning measurements. The wireless node transmits, to the network component, a report comprising the determined positioning estimate.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous reference signal transmission configuration. Certain aspects provide a method of receiving a configuration message from the base station, wherein the configuration message comprises an indication of a set of candidate resources for transmitting the reference signal. Certain aspects provide a method of detecting a future downlink transmission from the base station, and other aspects provide a method of transmitting, in response to detecting the future downlink transmission, the reference signal utilizing a first resource of the set of candidate resources prior to receiving the future downlink transmission via a second resource in the set of candidate resources.

Abstract: Methods, systems, and devices for wireless communications are described for management of conditional handover (CHO) configurations. A source base station may configure a user equipment (UE) with one or more CHO configurations for multiple target base stations. The CHO configurations may provide, for each target base station, one or more associated conditions that may trigger the UE to initiate a handover to the particular target base station, or to deconfigure a CHO configuration, such as based on a measurement threshold of one or more target base station measurements, one or more source base station measurements, or combinations thereof. The CHO configurations may also include failure handling information for initiating one or more subsequent handovers responsive to a failure of an initial handover attempt.

Abstract: Techniques are provide for calibrating device timelines for use in passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first device at a first time, receiving a second positioning reference signal from a second device at a second time, receiving a timeline difference value associated with the first device and the second device, and determining a time difference of arrival between the first positioning reference signal and the second positioning reference signal based at least in part on the timeline difference value.

Abstract: A first user equipment (UE) is configured to communicate with a second UE in sidelink communications using a sidelink configured grant (CG) configured by a base station. The first UE receives, a radio resource control (RRC) message or physical layer signaling including a sidelink configured grant (CG) configuration indicating at least some parameters configured by a base station for sidelink communications between the first UE and a second UE. The first UE transmits or receives a transport block for the sidelink communications on a physical sidelink shared channel (PSSCH) based on the at least some parameters.
