Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to transmit a compact uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU). The UE may transmit the UCI in the PRU based at least in part on a semi-static payload construction and resource mapping rule. Numerous other aspects are provided.

Abstract: A periodic quiet interval is provided for base stations attempting to access a shared transmission medium in NR-U. The base station activates a quiet interval at a periodic interval and transmits on the medium based on the quiet interval. The base station may reduce a Tx power, not transmit, and/or may increase a minimum value of a contention window for BEB during the quiet interval. The base station may receive a request from a second base station to activate the quiet interval, and may determine if a Tx power of the base station is larger than the maximum Tx power of the second base station. The base station may also receive the request as relayed through a UE. The quiet interval can thus ameliorate a starvation effect of BEB in NR-U by allowing base stations with smaller Tx power greater opportunity to control the medium while maintaining BEB in NR-U.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support relaxed sensing for new radio (NR) sidelink over millimeter wave (mmW) operating frequencies. In a first aspect, a method by a user equipment (UE) of wireless communication includes identifying a resource selection trigger that indicates selection of one or more sidelink slots from a resource selection window. The UE may obtain long-term interference sensing statistics observed by the UE prior to the resource selection trigger. The UE can reduce a default sensing window length in accordance with the long-term interference sensing statistics and transmit a sidelink transmission in the selected sidelink slots. Other aspects and features are also claimed and described.

Abstract: Wireless communications systems and methods related to multiplexing a sidelink-synchronization signal block (S-SSB) transmission with a physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) transmission for occupancy channel bandwidth (OCB) fulfilment are provided. A user equipment (UE) determines a multiplex configuration for multiplexing a sidelink transmission with a S-SSB transmission in a sidelink bandwidth part (BWP). The UE communicates, in the sidelink BWP during a sidelink slot, the S-SSB transmission. The UE communicates, in the sidelink BWP during the sidelink slot, the sidelink transmission, where the S-SSB transmission and the sidelink transmission are communicated by multiplexing the sidelink transmission and the S-SSB transmission based on the multiplex configuration.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for distance-based channel occupancy time (COT) sharing. In one aspect, a first device, such as a user equipment (UE), may determine an approximate distance between itself and a second device. The first device may receive a COT sharing configuration including a set of COT sharing parameters for sharing a COT of the communications link with the second device based on the distance between the two devices. The first device may determine conditions for sharing the COT based on the COT sharing configuration and the approximate distance between the two devices. Additionally, or alternatively, the first device may determine conditions for sharing the COT based on the COT sharing configuration and a power metric of communications between the two devices.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from two or more transmitters, two or more sidelink control informations (SCIs) that schedule channel occupancy time (COT) resources for the two or more transmitters. The receiver may transmit, to a transmitter of the two or more transmitters, an acknowledgement or negative acknowledgement (A/N) feedback via a mini-slot carrying a physical sidelink feedback channel (PSFCH) or sidelink feedback information (SLFI) with SCI. The A/N feedback may be transmitted before a listen-before-talk (LBT) and physical sidelink shared channel (PSSCH) transmission. The receiver may receive, from the transmitter using a COT resource, the PSSCH transmission based at least in part on the A/N feedback. The LBT and the PSSCH transmission may be adjustable at the transmitter based at least in part on the A/N feedback. Numerous other aspects are described.
