Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may receive, from a second device, a sounding reference signal (SRS) prior to a scheduled communication. The first device may transmit, to the second device, an indication that a measurement of the SRS does not satisfy a threshold, if the measurement of the SRS does not satisfy the threshold. The first device may activate, based at least in part on the transmitting the indication and before the scheduled communication, a multi-point communication mode. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, an indication of a first sidelink grant associated with a first set of resources. The UE may receive, from the network entity, an indication of a second sidelink grant associated with a second set of resources, wherein the first set of resources at least partially overlaps in a time domain with the second set of resources. The UE may perform an action based at least in part on the first set of resources at least partially overlapping in the time domain with the second set of resources. The UE may transmit one or more sidelink messages using at least one of the first sidelink grant or the second sidelink grant based at least in part on performing the action. 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, a first user equipment (UE) may transmit, to a second UE, a grant-only indicator to indicate that a second stage sidelink control information (SCI-2) is decoupled from physical sidelink shared channel (PSSCH) data in a slot, and that the SCI-2 indicates an SCI-2-only grant. The first UE may transmit, to the second UE in the slot, the SCI-2-only grant multiplexed with data-only traffic in a first PSSCH transmission based at least in part on the grant-only indicator, wherein the SCI-2-only grant indicates a resource allocation for a subsequent slot. Numerous other aspects are described.

Abstract: Aspects relate to techniques for facilitating sidelink cancellation of an automatic gain control (AGC) symbol of a sidelink transmission. A network entity, such as a base station, may transmit sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The network entity may further transmit a cancellation indication indicating an overlap between an AGC symbol of time resources allocated for the sidelink transmission and an additional transmission. Based on the cancellation indication, the transmitting wireless communication device may selectively transmit the sidelink transmission.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a target UE receives zone information associated with a set of zones, the zone information indicating, for each of a plurality of candidate UEs for a sidelink-assisted position estimation procedure of the target UE, a zone identifier of a zone in which the respective candidate UE is located. The target UE selects one or more candidate UEs for the sidelink-assisted position estimation procedure based at least in part upon the zone information. The target UE performs the sidelink-assisted position estimation procedure with at least the selected one or more candidate UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify that a sidelink communication is to be transmitted by the UE prior to a next sensing results sharing opportunity associated with a collaborative sensing schedule that is associated with resource selection for sidelink communications for a group of UEs that includes the UE. The UE may select resources for the sidelink communication. The UE may transmit the sidelink communication using the resources. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmit (Tx) user equipment (UE) may receive, from a base station, downlink control information (DCI) that triggers sidelink channel state information (CSI) reporting from a receive (Rx) UE to the Tx UE. The Tx UE may transmit, to the Rx UE, a request for CSI based at least in part on the DCI received from the base station. The Tx UE may receive, from the Rx UE, a CSI report based at least in part on the request. The Tx UE may transmit, to the base station, the CSI report received from the Rx UE. Numerous other aspects are described.
