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: Aspects relate techniques for facilitating resumption of a sidelink transmission after cancellation of the sidelink transmission within resources that overlap with an additional transmission. A transmitting wireless communication device may receive control information from a network entity including a cancellation indication indicating overlapping resources between the resources scheduled for the sidelink transmission and resources scheduled for the additional transmission. Based on the cancellation indication, the transmitting wireless communication device may cancel the sidelink transmission within cancelled resources including at least the overlapping resources and transmit the sidelink transmission via remaining resources of the scheduled resources for the sidelink transmission outside of the cancelled resources.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include mapping a transport block (TB) to a first sub-physical sidelink shared channel (sub-PSSCH) of a plurality of sub-PSSCHs of a PSSCH and transmitting, to at least one other UE, the TB via the first sub-PSSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving user equipment (UE) may receive, from a transmitting UE, a sidelink reference signal in a first symbol of a slot. The receiving UE may perform a joint channel estimation and an automatic gain control (AGC) based at least in part on the sidelink reference signal received in the first symbol of the slot. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate support of an extended cyclic prefix (ECP), where a duration of the ECP or transmitting the ECP is based on the indication. In some cases, the UE may receive an uplink grant to transmit an uplink message with an indication of the ECP, and the UE may transmit the ECP and uplink message according to a timeline based in part on the ECP. Additionally or alternatively, an uplink channel allocation indicated in the uplink grant may include a starting point for the ECP, where the UE transmits the ECP at the starting point. In some cases, the UE may multiplex uplink control information (UCI) in the uplink channel based on a timeline that is based in part on the ECP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant associated with a plurality of physical shared channel resources. The UE may transmit a communication indicating feedback for the plurality of physical shared channel resources using a slot offset value that is less than a decoding timeline for at least one of the plurality of physical shared channel resources. Numerous other aspects are described.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for configuring, in a slot, a low-latency transport block (TB) occupying one or more first temporal resources, a non-low-latency TB occupying one or more second temporal resources different from the one or more first temporal resources, and control information occupying at least a portion of the one or more first temporal resources, wherein the low-latency TB and the non-low-latency TB are time division multiplexed, and transmitting the low-latency TB and the non-low-latency TB via a physical sidelink shared channel (PSSCH) and the control information via a physical sidelink control channel (PSCCH) to one or more peer UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to another UE, a sidelink channel state information reference signal (S-CSI-RS) and an indication associated with triggering a non-codebook based precoded S-CSI-RS. The UE may receive, from the other UE, the non-codebook based precoded S-CSI-RS. The UE may transmit, to the other UE, a non-codebook based channel state information (CSI) report medium access control (MAC) control element (MAC-CE) that includes an indication of one or more selected precoding beams based at least in part on the non-codebook based precoded S-CSI-RS. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide improved techniques for monitoring a downlink control channel. For example, a method includes switching, at a first time period, to monitoring a downlink control channel according to a second group of search space sets in an unlicensed spectrum. The method further includes switching, after the first time period, to monitoring the downlink control channel according to a first group of search space sets in the unlicensed spectrum based on at least one of: i) expiration of a timer started based on the switching to monitoring the downlink control channel according to the second group of search space sets; or (ii) end of a channel occupancy time (COT), of a serving cell, during which the UE monitors the downlink control channel according to the second group of search space sets.
