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: Wireless communications systems and methods related to resource reservation for sidelink communication over a shared radio frequency band are provided. The method of wireless communication performed by a user equipment (UE) includes performing, in a shared radio frequency band, a listen-before-talk (LBT) for a first channel occupancy time (COT) and transmitting, during the first COT, a COT structure indicator, wherein the COT structure indicator reserves at least one resource within a second COT different than the first COT.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform blind decoding, for sidelink control information (SCI) in resources in one or more sub-channels of a sidelink resource pool, based at least in part on an aggregation level or a resource aggregation configuration. The UE may receive the SCI based at least in part on performing the blind decoding for the SCI. Numerous other aspects are described.

Abstract: Disclosed are techniques for communication. In an aspect, a position estimation entity includes determines common assistance data for a joint position estimation group, and sends to first and second UEs. The position estimation entity further sends indications of which PRS resources associated with the common assistance data is active for the first and second UEs. The position estimation entity receives measurement information from the first and/or second UEs, and derives position estimations of the first and second UEs.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a radio frequency identification (RFID) station may receive a first packet from an RFID tag at a first arrival time. The RFID station may receive a second packet from the RFID tag at a second arrival time after the first arrival time. The RFID station may estimate a distance between the RFID station and the RFID tag based on an inter-packet arrival time between the first packet and the second packet, the inter-packet arrival time being based on a time difference between the first arrival time and the second arrival time.

Abstract: A method for wireless communication by a first sidelink user equipment (UE) includes suppressing one or more signal peaks associated with a sidelink message based on a configuration for suppressing the one or more signal peaks associated with the sidelink message. The method also includes selectively transmitting, to a second sidelink UE, a peak information suppression message (PSIM) indicating the one or more suppressed signal peaks and/or one or more filled signal values based on suppressing the one or more signal peaks. The method further includes transmitting the sidelink message, to the second sidelink UE, based on suppressing the one or more signal peaks.
