Abstract: Information is communicated via a plurality of communication opportunities of a semi-persistent scheduling (SPS) occasion. A base station may transmit first information via a first communication opportunity of an SPS occasion and transmit second information via a second communication opportunity of that same SPS occasion. A wireless communication device may monitor all communication opportunities of an SPS occasion to decode the information sent in two or more of the communication opportunities of the SPS occasion.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include receiving, from a base station (BS), a resource pool (RP) configuration that indicates resources in a licensed frequency band reserved for sidelink control information (SCI), transmitting, to a second sidelink UE, the SCI in the reserved resources, wherein the SCI includes a starting position of channel occupancy time (COT) resources in an unlicensed frequency band, and transmitting, to the second sidelink UE, a physical sidelink shared channel (PSSCH) via the COT resources in the unlicensed frequency band.

Abstract: A method for wireless communications is presented. The method may be performed by a user equipment (UE) and includes receiving a multi-user physical (MUP) downlink shared channel (PDSCH) communication (MUPC) comprising a number of payloads. The method also includes transmitting an acknowledgement (ACK) in response to decoding the MUPC. The method further includes receiving a message requesting retransmission of at least one payload of the number of payloads. The method still further includes transmitting the at least one payload in response to the message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may encode, for a first set of resource elements (REs), a first layer for sidelink control information. The UE may encode, for a second set of REs, a second layer for sidelink data, wherein the first set of REs and the second set of REs are associated with a same one or more symbols. The UE may transmit, to another UE and based at least in part on applying superposition coded modulation (SCM) to the first layer and the second layer, the sidelink control information using the first set of REs and the sidelink data using the second set of REs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine, within a channel occupancy time shared with a second UE, one or more contention slot starting times based at least in part on a listen before talk duration and an automatic gain control duration. The first UE may transmit a sidelink communication to the second UE at a starting time selected from one or more of the one or more contention slot starting times. Numerous other aspects are provided.

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 power reservation signal of a sub-slot resource pool (RP) to an AGC symbol location of a slot RP and transmitting, to at least one other UE, the power reservation signal, wherein a transmit power level of the power reservation signal is based on an estimated transmit power level associated with at least one sub-slot.

Abstract: Wireless communications systems and methods related to resource reservation for sidelink communication over a shared radio frequency band are provided. The method of wireless communication performed by a user equipment (UE) includes performing, in a shared radio frequency band, a listen-before-talk (LBT) for a first channel occupancy time (COT) and transmitting, during the first COT, a COT structure indicator, wherein the COT structure indicator reserves at least one resource within a second COT different than the first COT.

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.
