Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques to achieve inter-base station beam management to avoid interference during full-duplex (FD) operations, half-duplex (HD) operations, flexible time-domain duplexing (TDD), or a combination thereof, by performing interference management specific to beam configurations. For example, a first base station (e.g., an aggressor base station operating in FD) may perform one or more actions to proactively determine if inter-base station interference may occur. In some cases, the aggressor base station may request measurements from one or more victim base stations. In other examples, the victim base station may request measurements from the aggressor base station. Additionally or alternatively, the victim base station may provide reactive feedback to the aggressor base station upon detecting interference.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for establishing directional communications between two communication nodes via a configurable reflective surface. In some aspects, an assisting node (AN) may control a reflection characteristic (which may dictate or influence how signals reflect off of the configurable reflective surface) in accordance with parameters or configurations for directional communication between the two communication nodes. For example, the AN may use a first beam for directional communication with the first node and a second beam for directional communication with the second node, and the AN may control the reflection characteristic in accordance with an inferred incident direction of signaling at the configurable reflective surface and a desired reflected direction of the signaling from the configurable reflective surface that are associated with the first beam and the second beam, respectively.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify an applicable restricted resource scheduling rule for restricting full-duplex operation on a first set of resources. The base station may transmit one or more control messages scheduling one or more full-duplex communications on a second set of resources based on the applicable restricted resource scheduling rule for restricting full-duplex operation on the first set of resources. In some examples, the second set of resources may overlap in time with the first set of resources. In other examples, the second set of resources may not overlap with the first set of resources in time or frequency. Accordingly, the base station may communicate the one or more full-duplex communications on the second set of resources. The described techniques may enable the base station to perform full-duplex communications with reduced interference and improved reliability.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a first device may receive a feedback message from a second device that indicates a set of one or more sensing results associated with a sensing procedure performed by the second device. The first device may transmit, to the second device, a control message indicating resource information for a message for the second device. The control message may include an indication of a transmission configuration indication (TCI) state indicating a quasi-colocation (QCL) relationship between a reference signal associated with the message and a sensing result of the set of one or more sensing results indicated by the feedback message. The first device may transmit the message using a transmit beam and the second device may receive the message using a receive beam based on the TCI state and the QCL relationship.

Abstract: Methods, apparatuses, and computer-readable storage medium for SL communications are provided. An example method may include transmitting, to one or more UEs, an SL transmission in a first direction using a first precoder. The example method may further include retransmitting, to the one or more UEs based on a configured maximum number of directional retransmissions and without allocating additional processes and memory for the packet, the SL transmission in one or more directions different from the first direction using one or more precoders different from the first precoder based on a SL retransmission configuration.

Abstract: Systems, methods, and devices for wireless communication that support resource selection and indication for sidelink demodulation reference signal (DMRS) bundling. A transmitting UE determines sidelink resources for bundling a sidelink DMRS transmission to be transmitted to a receiving UE. In sidelink mode 1, the sidelink resources may be determined based on indications from a base station, which may include whether the transmitting UE is to maintain phase continuity over the sidelink resources during the bundling, or whether the transmitting UE is to include a phase jump reference signal with the bundled DMRS transmission to the receiving UE. In sidelink mode 2, the transmitting UE may select the sidelink resources based on the phase continuity capabilities of the transmitting UE and/or of the receiving UE, and/or based on a sensing of the sidelink channel. In some cases, the receiving UE may provide a resource recommendation to the transmitting UE.
