Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may support communications with a set of transmission/reception points (TRPs). The UE may receive one or more signals from at least one TRP of the set of TRPs. The one or more signals may indicate a condition corresponding to the UE for the multi-TRP communications. The UE may determine the condition of the UE based on the one or more signals. The UE may communicate with one or more TRPs of the set of TRPs based on the one or more signals. For example, the UE may communicate with the one or more TRPs according to a multi-TRP communications configuration determined based on the condition of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A set of user equipments (UEs) may communicate with each other on communication links using data resources from a pool of shared resources. The UEs may be configured to multiplex control resources with data resources of a shared resource pool. In some cases, a UE may communicate, in control resources, control signaling to reserve data resources of a shared resource pool. After transmitting the request, the UE may communicate data in one or more data resources. The UE may communicate the data using transmission components while concurrently processing control signaling using other components.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a first communication device may receive, from a second communication device, control signaling triggering a channel access procedure at the first communication device. In some case, the channel access procedure may be for accessing the shared radio frequency spectrum. The first communication device may then perform the channel access procedure based on the control signaling. In some examples, the first communication device may, based on the channel access procedure, transmit an indication of a channel occupancy initiated by the first communication device to the second communication device. The first communication device may relay communications between the second communication device and a third communication device during a channel occupancy time (COT) based on the transmitted indication of the channel occupancy initiated by the first communication device.

Abstract: Methods, systems, and devices for wireless communications are described that provide for directional quality of service (QoS) targets of a user equipment (UE) for directional communications to multiple UEs in multiple directions. An application layer of the UE may provide data with multiple different directional QoS targets, that may be mapped to multiple QoS data flows that are each configured with different directional QoS targets such as direction and priority associated with the direction. The data may be duplicated for each of the multiple QoS data flows having different QoS parameters, and each QoS data flow may be transmitted in a different direction using a different beam.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, wireless devices may communicate using reconfigurable intelligent surfaces (RIS) for improved spatial diversity. A base station may transmit, to a user equipment (UE), control signaling indicating a configuration for a channel state information (CSI) reference signal (RS) resource set corresponding to one or more RISs and a communication beam threshold for the one or more RISs. The CSI-RS resource set may be specific to one RIS or may configure resources for multiple RISs. The UE may receive, according to the CSI-RS resource set, a set of CSI-RSs corresponding to a set of respective communication beams (e.g., reflected beams from the one or more RISs). The UE may transmit a CSI report indicating one or more communication beams selected by the UE based on the set of CSI-RSs and the communication beam threshold.

Abstract: Certain aspects of the present disclosure provide techniques for direct TB forwarding. In aspects, a relay node receives, from a source node, an indication to directly forward one or more TBs to one or more destination nodes, wherein directly forwarding includes transmitting a TB of the one or more TBs to the one or more destination nodes through only a PHY layer and a HARQ portion of a MAC layer in a protocol stack of the relay node, receives, from the source node, control information for one or more data channels configuring: one DL grant and two or more SL grants, or two or more DL grants and one SL grant, decoding one or more TBs based, at least in part, on the control information, and directly forwards the one or more TBs to the one or more destination nodes based on the indication and the control information.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance functionality of directional repeaters (for instance, wireless devices that relay directional wireless signals). By adding even limited capability within the directional repeaters to buffer digital samples, the functionality of the directional repeaters may be enhanced to provide better coverage and make more efficient use of time, frequency, and spatial resources.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device may receive control signaling indicating a configuration for reporting a set of beam angle measurement values between at least two beams relative to a respective beam of a set of beams and a phase difference measurement value between post-beamformed channel phases using the at least two beams of the set of beams. In some examples, the communication device may determine a set of reference signal received power (RSRP) measurement values associated with the at least two beams of the set of beams. The communication device may transmit a report including the set of beam angle measurement values and the phase difference measurement value based on receiving the control signaling indicating the configuration. For example, the communication device may report the RSRP measurement values associated with the at least two beams of the set of beams.

Abstract: A node may activate, in each iteration of a plurality of iterations, a respective segment of a plurality of segments of an IRS of the node. Each iteration of the plurality of iterations may correspond to one segment of the plurality of segments. The apparatus may receive, from the first wireless device, an indication of a second configuration for the node to generate one or more reflected beams toward the first wireless device or the second wireless device. The second configuration may be based on an interpolation process based on a plurality of phases or phase derivatives associated with the plurality of segments. The apparatus may forward, from the first wireless device to the second wireless device or from the second wireless device to the first wireless device, communications via the IRS based on the second configuration and the one or more reflected beams.
