Abstract: A method of wireless communication includes determining, by a communication device, a value of a counter associated with a listen-before-talk (LBT) operation. The method further includes, after determining the value of the counter and during a first portion of a deferral interval associated with the LBT operation, performing a first measurement of a particular duration to determine a first energy value. The method further includes, during a second portion of the deferral interval subsequent to the first portion, performing a second measurement of the particular duration to determine a second energy value. The method also includes determining whether to initiate a contention interval associated with the LBT operation based on the first energy value and further based on the second energy value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmit (Tx) user equipment (UE) may receive, from a base station, downlink control information (DCI) that triggers sidelink channel state information (CSI) reporting from a receive (Rx) UE to the Tx UE. The Tx UE may transmit, to the Rx UE, a request for CSI based at least in part on the DCI received from the base station. The Tx UE may receive, from the Rx UE, a CSI report based at least in part on the request. The Tx UE may transmit, to the base station, the CSI report received from the Rx UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described for block feedback of multiple semi-persistent scheduling (SPS) occasions. Block feedback may be provided based on variable feedback timing values that are associated with one or more SPS occasions. A user equipment (UE) may determine feedback for each of two or more SPS occasions, and transmit a block feedback that indicates the feedback. A separate feedback timing between a SPS occasion and uplink feedback resources may be provided for multiple SPS occasions, which are associated with a single uplink feedback resource. Alternatively, a minimum feedback timing value and a maximum feedback timing value may be configured for a particular uplink resource, and block feedback for multiple SPS occasions within the minimum and maximum feedback timing values may be reported in the uplink feedback resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine candidate resources on one or more physical sidelink shared channels (PSSCHs) that are clear for transmitting at least two transport blocks, based at least in part on sensing a plurality of subchannels on the one or more PSSCHs with respect to listen-before-talk completion instants for the at least two transport blocks. The UE may select, from among the candidate resources, transmit resources on the one or more PSSCHs for transmitting the at least two transport blocks such that the at least two transport blocks are transmitted in one of: different subchannels of a same slot, or contiguous slots of a same subchannel. The UE may transmit the at least two transport blocks in the transmit resources. Numerous other aspects are provided.

Abstract: Aspects relate to techniques for facilitating sidelink cancellation. A network entity, such as a base station, may schedule a sidelink transmission between a transmitting wireless communication device and a receiving wireless communication device and transmit scheduling information for the sidelink transmission to at least the transmitting wireless communication device. The network entity may further transmit control information including a cancellation indication to at least the transmitting UE. The cancellation indication may indicate at least an overlap between a portion of the resources allocated to the sidelink transmission and an additional transmission. Based on the cancellation indication, the transmitting wireless communication device may modify the sidelink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a group-common physical downlink shared channel (PDSCH), where the group-common PDSCH is repeated for a number of repetitions. Accordingly, the UE may determine this number of repetitions and then monitor for the group-common PDSCH based on the number of repetitions. In some implementations, the group-common PDSCH may include a semi-static repetition scheme, where the number of repetitions is indicated via a group aggregation factor. Additionally or alternatively, the group-common PDSCH may include a dynamic repetition scheme, where the number of repetitions is indicated via a group repetition number. Additionally, the techniques described herein may enable the configuration for the repeated group-common PDSCH to include gaps between each repetition of the group-common PDSCH and for the UE to transmit acknowledgment feedback for the repetitions of the group-common PDSCH.
