Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) performs a first channel access procedure for accessing a channel occupancy time (COT) within the sidelink channel. The UE transmits a second-stage sidelink control information (SCI) message (SCI-2) including COT sharing information (COT-SI) for sharing the COT with other devices, and transmits a first sidelink message within a first portion of the COT. The UE identifies a second sidelink message that is expected to be received within a second portion of the COT, and performs a second channel access procedure for accessing the COT after identifying the second sidelink message based on the second sidelink message being expected within a set of resources reserved for the second sidelink message. Subsequently, the UE transmits a third sidelink message within a third portion of the COT based on a completion of the second channel access procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication associated with performing listen-before-talk relative to a channel occupancy time (COT). Accordingly, the UE may transmit, to the base station, an uplink communication, where the uplink communication is transmitted using a listen-before-talk (LBT) procedure based at least in part on the indication. For example, the LBT procedure may be selected from a category 1 (Cat1) LBT procedure, a category 2 (Cat2) LBT procedure, or a category 3 (Cat3) LBT procedure based at least in part on the indication (e.g., included in a radio resource control message). The LBT procedure may be further based at least in part on downlink control information from the base station. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for determining whether to drop an additional signal at an edge interlaced resource block (IRB) of a common interlace. A user equipment (UE) may transmit additional signals via IRBs of the common interlace to improve an occupied channel bandwidth (OCB) of a feedback transmission and may drop one or more additional signals that are proximate (e.g., in frequency) to feedback indications of a configured interlace. To ensure the OCB of the transmission satisfies an OCB threshold, the UE may determine whether to drop an additional signal at an edge IRB, despite the edge IRB being proximate to a feedback indication, according to one or more rules that may be specific to edge IRBs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from one or more base stations, scheduling information for a multi-beam communication using a set of beams between the UE and the one or more base stations. The UE may perform, with the one or more base stations, the multi-beam communication based at least in part on: receiver assistance information for one or more beams in the set of beams associated with the multi-beam communication, and a policy to fulfil a grant according to the scheduling information, partially fulfil the grant according to the scheduling information, or not fulfil the grant according to the scheduling information using the receiver assistance information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described to support accounting for contention-exempt synchronization signal blocks (SSBs) when validating one or more channel state information reference signals (CSI-RS). A base station may transmit, to a user equipment (UE), an indication of the one or more contention-exempt SSBs, and the UE may determine to monitor for a configured CSI-RS if resources assigned to the CSI-RS fall within a time frame associated with the one or more contention-exempt SSBs. Similarly, the base station may transmit configured CSI-RS if resources assigned to the CSI-RS fall within a time frame associated with the one or more contention-exempt SSBs. The time frame associated with the one or more contention-exempt SSBs may include a slot that includes the SSB(s), a symbol that includes the SSB(s), symbols between the SSB(s), slots between the SSB(s), or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a multiple-slot unit structure that is to be used for sidelink communication, the multiple-slot unit structure having multiple contiguous slots that include, in sequence, a first time interval for automatic gain control, a second time interval for at least one of sidelink control communication or sidelink data communication, and a third time interval providing a time gap for transmission-reception switching. The UE may communicate, on a sidelink, in one or more multiple-slot units that are in accordance with the multiple-slot unit structure. Numerous other aspects are described.
