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: 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.

Abstract: A method of wireless communication performed by a user equipment (UE) may include: receiving, from a base station (BS), first downlink control information (DCI) scheduling an uplink (UL) communication; receiving, from the BS, a request to perform a clear channel assessment (CCA) associated with a first CCA timing configuration; performing, based on an indication to change to a second CCA timing configuration different from the first CCA timing configuration, the CCA based on the second CCA timing configuration; and transmitting, to the BS based on the CCA, the UL communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting node may determine a set of geometry-specific parameters based at least in part on a symbol sequence length n and a target distribution. The transmitting node may determine a sequence of K bits based at least in part on a plurality of information bits and a bit sequence length K. The transmitting node may map, based at least in part on a composition selected from a plurality of compositions, the sequence of K bits to a sequence of n symbols using arithmetic coding based at least in part on the set of geometry-specific parameters. The transmitting node may transmit the sequence of n symbols to a receiving node. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically indicating or determining channel occupancy time (COT) for uplink transmissions. For example, a user equipment (UE) may determine whether a scheduled uplink transmission is based on CE-initiated COT or sharing a network initiated COT (both generally referred to as “COT types”) based on content in the scheduling downlink control information (DCI) or a rule applied for a configured uplink transmission. The present disclosure provides techniques for determining the COT types by using corresponding fields in the DCI when applicable, or when the corresponding fields are absent, by introducing rules configuring the uplink transmission.

Abstract: A method of wireless communication performed by a user equipment (UE) includes receiving, from a base station (BS) in a first fixed frame period (FFP), downlink communication information (DCI), where the DCI indicates a scheduled DL communication in a second FFP subsequent to the first FFP. The method also includes monitoring for a downlink (DL) signal in the second FFP. The method also includes transmitting, based on the monitoring for the DL signal, an acknowledgement/non-acknowledgement (ACK/NACK) indicating whether the scheduled DL communication was detected.

Abstract: Certain aspects of the present disclosure provide techniques for determining a relay capability configuration for using a control signal to schedule a physical sidelink shared channel (PSSCH) that carries information to organize sidelink connections. The control signal allows user equipments (UEs) to organize a sidelink network absent base station configurations or vendor configurations. For example, the control signal may schedule a discovery signal (DS) associated with a sidelink synchronization signal block (S-SSB). The control signal may be referred to as DS-physical sidelink control channel (DS-PSCCH), different from a normal PSCCH. The DS-PSCCH may have distinct structure and content to allow UEs to organize sidelink networks.
