Abstract: Aspects relate to mechanisms for improved uplink and sidelink coverages. A first network entity determines one or more channel state feedback (CSF) parameters of one or more beams associated with the first network entity, selects one or more beam coefficients based on the one or more CSF parameters, and transmits the one or more beam coefficients to at least a second network entity. The second network entity selects one or more beams for beaming forming based on the one or more beam coefficients, determines one or more CSF parameters of the one or more beams associated with the second network entity, and transmits the one or more CSF parameters of the one or more beams associated with the second network entity to the first network entity. The first network entity selects one or more new beam coefficients based on the one or more CSF parameters from the second network entity.

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.

Abstract: A method of wireless communication by a base station, jointly processes channel information associated with a user equipment, UE, in order to generate a jointly processed report. The channel information is collected from collocated transmit and receive points, TRPs (604, t1, t2, t3), of the base station. The base station transmits (t5) the jointly processed (t4) report to a location server (112).

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) monitors one or more physical downlink control channel (PDCCH) candidates in a search space while in a radio resource control (RRC) inactive state, receives, while in the RRC inactive state, a positioning paging message from a network entity on at least one PDCCH candidate of the one or more PDCCH candidates, the positioning paging message configured to trigger an update to one or more parameters associated with an ongoing positioning session involving the UE, applies, while in the RRC inactive state, the update to the one or more parameters, and transmits, while in the RRC inactive state, an acknowledgment to the network entity in response to reception of the positioning paging message.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a method of wireless communication performed by a base station (BS) includes obtaining a resource-level muting bitmap for a reconfigurable intelligent surface (RIS), wherein the resource-level muting bitmap identifies sets of time and frequency resources during which the RIS should be enabled to reflect a transmission beam or disabled from reflecting a transmission beam, and requesting the RIS to be enabled or disabled according to the resource-level muting bitmap.

Abstract: In an aspect, a position estimation entity may obtain a first differential round trip time (RTT) measurement based on a first RTT measurement between a user equipment (UE) and a first wireless node and a second RTT measurement between the UE and a second wireless node, may obtain a second differential RTT measurement based on a third RTT measurement between a third wireless node and the first wireless node and a fourth RTT measurement between the third wireless node and the second wireless node, and may determine a positioning estimate of the UE based at least in part on the first differential RTT measurement and the second differential RTT measurement.

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.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits a first signal for positioning (RS-P) (e.g., SRS, etc.) on a first link from the UE to a wireless network node (e.g., BS, UE, etc.). The UE receives, from the wireless network node, location assistance data that comprises information that indicates a line of sight (LOS) condition associated with the first link. The UE measures a second RS-P on a second link from the wireless network node to the UE that is reciprocal to the first link. The UE performs one or more positioning measurements, determines a location estimate of the UE, or both, based in part on the reception of the second RS-P on the second link and the indicated LOS condition, the indicated LOS condition associated with the second link based on link reciprocity between the first and second links.

Abstract: A method for wireless communication by a user equipment (UE) includes transmitting, to a base station, an uplink capability message indicating a coherent uplink multiple-in-multiple-out (MIMO) capability associated with coherent transmission characteristics. The method also includes receiving, from the base station, a switch parameter that configures the UE for a transmission chain switch. The method further includes receiving, from the base station, a switching message that triggers the transmission chain switch between a reference signal (RS) transmission and a scheduled data communication. The method still further includes transmitting the data communication according to one or more non-coherent transmission characteristics based on the transmission chain switch being triggered between the RS transmission and the scheduled data communication.

Abstract: Position determination for a target user equipment (UE) uses a single base station and a plurality of sidelink UEs with known locations. The base station sends a reference signal to the target UE and sidelink UEs, and the target UE sends sidelink signals to each sidelink UEs. A range-sum for the range between the target UE and sidelink UE and the range between the sidelink UE and the base station can be determined for each sidelink UE, based on the time differences between the reception and transmissions of the reference signals measured by the target UE, and the time difference between reception of the reference signals measured by the sidelink UE. A differential in the range-sums can be determined and used to determine the position of the target UE.
