Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node and via a buffer status report (BSR) or scheduling request (SR), a request indicating one or more parameters associated with sidelink communications in an unlicensed spectrum. The UE may receive, from the network node, a sidelink resource allocation indicating one or more resource block (RB) sets associated with the unlicensed spectrum. The UE may transmit, to a sidelink UE and based at least in part on the sidelink resource allocation and on a result of performing listen-before-talk (LBT), a sidelink communication. 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 receive, from a network node, a multi-cell downlink control information (MC-DCI) that indicates scheduling information for co-scheduled component carriers (CCs), wherein the MC-DCI indicates one or more of an antenna port(s) field or a modulation and coding scheme (MCS) field to be commonly applied to one or more of the co-scheduled CCs. The UE may perform a transmission based at least in part on the scheduling information indicated by the MC-DCI. 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 group discontinuous reception (DRX) configuration. The UE may receive, based on the group DRX configuration, a notification communication indicative of group handover information associated with a group of UEs that includes the UE. The UE may perform, based on the group handover information, a group handover operation between a source cell and a target cell. Numerous other aspects are described.

Abstract: Systems and techniques are provided for wireless communications. For example, an apparatus (e.g., a user equipment (UE)) may receive a downlink transmission in a first downlink time slot and receiving an update to a scheduling offset associated with a propagation time delay of communications between the apparatus and a network entity. The update indicates an updated scheduling offset. The apparatus may determine a selected scheduling offset as one of the scheduling offset or the updated scheduling offset. The apparatus may transmit, using a second uplink time slot, an uplink transmission associated with the downlink transmission. The second uplink time slot may be determined based on a first uplink time slot and the selected scheduling offset.

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, an indication of a scheduling offset associated with a hybrid automatic repeat request (HARQ) acknowledgement (ACK) codebook.

Abstract: Aspects described herein relate to decoding downlink control information (DCI) based on multiple DCI sizes. A first hypothesis of multiple hypotheses for decoding a communication received in a control channel search space, wherein the multiple hypotheses are based on different corresponding DCI sizes can be determined. The communication received in the control channel search space can be decoded based on the first hypothesis. For each of the multiple hypotheses and based on the different corresponding DCI sizes, information bits can be extracted from the communication as decoded. For each extracting of the information bits, cyclic redundancy check (CRC) can be performed based on one of the different corresponding DCI sizes to determine whether extracting of the information bits yields DCI.
