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: Certain aspects of the present disclosure provide techniques for over-the-air synchronization of integrated access and backhaul communications. An example method that may be performed by a network entity includes receiving, from a first wireless node, an indication of a value of a timing adjustment factor associated with a communication between the first wireless node and a second wireless node and communicating with the first wireless node or the second wireless node based on the value of the timing adjustment factor.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a first set of resources for an access link communication between the first UE and a base station. The UE may identify a second set of resources for a sidelink communication between the first UE and a second UE. The UE may identify a scheduling conflict between the first set of resources for the access link communication and the second set of resources for the sidelink communication. The UE may drop at least a portion of the first set of resources for the access link communication or the second set of resources for the sidelink communication based at least in part on the identification of the scheduling conflict and a prioritization rule. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for enhanced sidelink (SL) control signaling with time division duplexing (TDD). A method that may be performed by a first user equipment (UE) may include receiving a TDD configuration indicating resources of a resource pool available for SL transmissions between the first UE and at least a second UE and exchanging SL communications with the second UE in one or more slots or symbols based, at least in part, on the TDD configuration. The TDD configuration may define one or more of the slots or symbols as flexible slots or symbols that may be configured as downlink (DL) or uplink (UL) slots or symbols. The TDD configuration may also identify one or more of the slots or symbols as UL slots or symbols and one or more slots or symbols as DL slots or symbols.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining shared resources associated with one or more user equipments (UEs) for sidelink communications, including control resources and data resources. A first UE may determine a first set of control resources in a first frequency band corresponding to a first group of UEs including the first UE. The first UE may transmit a sidelink request to reserve a subset of data resources to a second UE in the first group of UEs. The first UE may monitor for one or more sidelink responses indicating a positive sidelink response to the sidelink request, a negative sidelink response to the sidelink request, or both. The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the data resources to the second UE.
