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: The aspects described herein may improve beam management at an apparatus (e.g., a UE) by allowing the apparatus to proactively transmit a beam report including information that may avoid a full beam failure recovery (BFR) procedure at the apparatus. The apparatus receives a set of beam failure detection reference signals and transmits a beam report indicating a partial beam failure when a radio link quality of at least a first beam failure detection reference signal in the set of beam failure detection reference signals is less than a quality threshold and a radio link quality of at least a second beam failure detection reference signal in the set of beam failure detection reference signals is greater than or equal to the quality threshold.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first user equipment (UE) may include transmitting, to a second UE, first stage sidelink control information (SCI-1) using a first set of resources of a resource pool (RP), wherein the RP indicates resources reserved for communicating the SCI-1 and transmitting, to the second UE, the SCI-1 using a second set of resources of the RP, wherein the second set of resources is different from the first set of resources

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: Dynamic grants (DG) for retransmission by a user equipment (UE) use the communication resource more efficiently while configured grants (CG) for retransmission by the UE reduce overhead and latency. A base station (BS) uses radio resource control signaling to configure the UE with a retransmission timer or without a retransmission timer. The BS transmits to the UE a set of CG configurations configuring a set of configured grant uplink (CG-UL) processes. The set of CG configurations includes information indicating whether or not a cg-RetransmissionTimer is associated with the CG-UL processes. The BS is also configured to receive communication on UL from the UE. The communication from the UE is received based on the set of CG-UL processes and the indication whether or not a cg-RetransmissionTimer is associated with the CG-UL processes. A UE may have different channel conditions for a plurality of CG-UL processes of the UE and therefore using a combination of CG based retransmission and DG based retransmission will reduce latency and reduce overhead and use the resource more efficiently.
