Abstract: Aspects relate to sharing a channel occupancy time (COT) initiated by a network access node (e.g., a base station) with one or more wireless communication devices for sidelink communication between the wireless communication devices. In this example, the network access node can transmit a COT structure indication (COT-SI) to the wireless communication device(s) indicating the COT resources (e.g., time and frequency resources) of the COT that may be shared with sidelink. In some examples, the wireless communication device can receive a message from the network access node including a COT sharing indicator indicating whether COT sidelink sharing is enabled or disabled.

Abstract: A method of wireless communication performed by a first user equipment (UE) comprises transmitting, in a first channel occupancy time (COT), a first sidelink (SL) data communication in a first RB-set to a second UE, and a second SL data communication in a second RB-set to a third UE. The method further includes receiving, from the second UE in the first COT: a first SL feedback communication in the first RB-set; and a repetition of the first SL feedback communication in the second RB-set. The method further includes transmitting, to the second UE in the first COT after the receiving the first SL feedback communication, a third SL data communication in the first RB-set, and transmitting, to the third UE in the first COT after receiving the repetition of the first SL feedback communication, a fourth SL data communication in the second RB-set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical sidelink shared channel (PSCCH) transmission that uses unlicensed spectrum. The UE may select a resource block (RB) configuration for one or more resource blocks (RBs) that are associated with a physical sidelink feedback channel (PSFCH) transmission, the RB configuration being based at least in part on the unlicensed spectrum. The UE may transmit an acknowledgement (ACK)/negative acknowledgement (NACK) response to the PSCCH transmission based at least in part on using the PSFCH and the RB configuration for the one or more RBs. Numerous other aspects are described.

Abstract: Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a first user equipment (UE) includes transmitting, to a second UE, a first sidelink synchronization block (S-SSB) in a first subset of a bandwidth, wherein the first S-SSB comprises a first sequence shift and a first identifier associated with the first UE and transmitting, to the second UE, one or more additional S-SSBs in one or more additional subsets of the bandwidth, wherein the one or more additional S-SSBs comprises at least one of a second sequence shift different from the first sequence shift or a second identifier associated with the first UE different from the first identifier associated with the first UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may receive an indication of a detection of a scheduling collision of a first scheduled communication of a first scheduling message from the first TRP and a second scheduled communication of a second scheduling message from a second TRP. The first TRP may back off from transmitting the first scheduled communication based at least in part on the indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message that indicates a set of demodulation reference signal (DMRS) ports for DMRS communication between the UE and a network entity. The UE may select a subset of DMRS ports from the set of DMRS ports for DMRS bundling across a set of transmission occasions. The subset of DMRS ports may have fewer DMRS ports than the set of DMRS ports. The UE may communicate a set of DMRSs with the network entity over the set of transmission occasions using the set of DMRS ports. A portion of the set of DMRSs may correspond to the subset of DMRS ports, may satisfy a power condition for DMRS bunding, and may satisfy a phase continuity condition for DMRS bundling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may receive a first control channel associated with a multiple relay based communication. The node may identify a target node of a pay load of the first control channel based at least in part on at least one of: information included in the payload, or an identifier associated with the first control channel. The node may transmit a second control channel carrying the pay load toward the target node if the node is not the target node. The node may decode the payload, if the node is the target node. Numerous other aspects are described.
