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, a synchronization signal block (SSB). The UE may perform a measurement of the SSB during a measurement window for an unlicensed spectrum, wherein the measurement window is an extended measurement window as compared to a scheduled measurement window for a licensed carrier. The UE may transmit, based at least in part on the measurement of the SSB during the measurement window, a configured grant small data transmission (CG-SDT) in the unlicensed spectrum to the network entity, wherein the CG-SDT is based at least in part on a timing alignment validation after the measurement window. Numerous other aspects are described.

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 identify a first resource for a sidelink feedback channel associated with the UE, wherein the sidelink feedback channel is associated with a first radio access technology (RAT). The UE may transmit, using a second RAT, a reservation for a second resource that overlaps the first resource. 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 a multiple physical uplink shared channel (multi-PUSCH) configuration, assign a first hybrid automatic repeat request (HARQ) process identifier (HPID) and one or more redundant version identifiers (RVIDs) to two or more slots associated with a first transport block, and assign a second HPID and the one or more RVIDs to two or more slots associated with a second transport block. The first transport block and the second transport block may be part of a single configured grant period. Assigning the second HPID may include incrementing the first HPID using one or more of a physical slot count, an available slot count, or a repetition number. The UE may transmit a multi-PUSCH communication in accordance with the multi-PUSCH configuration. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects relate generally to control channel monitoring adaptation for a multicast broadcast service (MBS). Some aspects more specifically relate to defining an applicability of control channel monitoring adaptation for a search space that is configured for monitoring a control channel associated with the MBS. In some aspects, a user equipment (UE) may receive a configuration for a search space for monitoring a control channel for downlink control information (DCI) that is associated with the MBS. Additionally, one or more control channel monitoring adaptation parameters may be applicable to the search space. In some aspects, an application of control channel monitoring adaptation when monitoring the control channel (via the search space) for DCI that is associated with the MBS may be associated with a radio resource control state of the UE.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a configuration, for synchronization of a communication link, of a plurality of component carriers (CCs) and respective priorities associated with the plurality of CCs and may receive a plurality of synchronization signals (SSs) via the plurality of CCs. The UE may synchronize with a timing source associated with a wireless device associated with a first CC of the plurality of CCs, and may transmit SSs via one or more of the plurality of CCs. The UE may select the first CC and may transmit the SSs via the one or more of the plurality of CCs based on the respective priorities associated with the plurality of CCs, respective received signal powers of the SSs, a synchronization source priority of the wireless device, one or more reference carriers, or any combination thereof.
