Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may start, in a no-listen-before-talk (no-LBT) mode and after a first channel occupancy time (COT), an away period during which no transmissions are to occur in abeam direction used in the first COT. The wireless communication device may perform, during the away period, channel sensing. The wireless communication device may transmit a communication in a second COT after the away period, based at least in part on a result of the channel sensing. Numerous other aspects are described.

Abstract: A method for wireless communication at a first sidelink user equipment (UE) includes performing, in a shared radio frequency band, a listen-before-talk (LBT) for a channel occupancy time (COT). The method also includes selecting a full-slot sidelink channel waveform hypothesis associated with a first starting symbol, or a half-slot sidelink channel waveform hypothesis associated with a second starting symbol, in accordance with a timing associated with clearing the LBT. The method further includes transmitting, during the COT, sidelink information to a second sidelink UE, a transport block size (TBS) associated with the COT having a fixed number of resources, the fixed number of resources being a same number of resources for full-slot sidelink channel waveform hypothesis and the half-slot sidelink channel waveform hypothesis.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sidelink synchronization signal block (S-SSB) in a slot. The UE may transmit remaining minimum system information (RMSI) associated with the S-SSB, wherein the RMSI is transmitted in a physical sidelink shared channel (PSSCH) that is multiplexed with the S-SSB in the slot. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for including physical layer RSSI in CSI reporting. In some cases, a method for wireless communications by a user equipment (UE) includes receiving a channel state information (CSI) reporting configuration that specifies physical layer received signal strength indicator (RSSI) measurement as a report quantity, performing physical layer RSSI measurement, and reporting the RSSI to a network entity in accordance with the CSI reporting configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting user equipment (UE) may obtain an indication of a sidelink synchronization signal block (SSB) candidate index associated with a sidelink SSB transmission. The UE may transmit, to a receiving UE, the indication of the sidelink SSB candidate index, the indication of the sidelink SSB candidate index being included in a sidelink SSB. 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.
