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: 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.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sidelink assistance for communication between a user equipment (UE) and a network entity. In some aspects, a set of UEs and a network entity may support one or more signaling mechanisms according to which at least one UE is able to assist other UEs in receiving or obtaining information to use for communication with the network entity. For example, a first UE may receive assistance information from a second UE and may use the received assistance information for communication between the first CE and the network entity or may otherwise operate in accordance with the received assistance information. Such assistance information may include an indication of a system information change, a public warning signal (PWS) notification, one or more signal strength measurements, or uplink transmission information.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may identify, in a radio frequency spectrum band a first resource for a sidelink synchronization signal block (S-SSB) and may perform a channel access procedure for the radio frequency spectrum band for the first resource. In a first example, a second resource for a sidelink message may overlap in time with the first resource and the UE may perform the channel access procedure based on the S-SSB being prioritized over the sidelink message. In a second example, the UE may perform the channel access procedure in accordance with a first value of a parameter for the channel access procedure associated with a first synchronization priority based on the UE being associated with the first synchronization priority. The UE may transmit an S-SSB over the first resource based on the channel access procedure indicating availability.
