    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station central unit (CU) may transmit, and a second base station CU may receive, first inter-CU signaling including information related to cross-link interference (CLI) experienced by or to be measured by one or more victim downstream nodes associated with the first base station CU. The second base station CU may configure one or more aggressor downstream nodes to transmit one or more signals based at least in part on the first inter-CU signaling. The second base station CU may transmit, and the first base station CU may receive, second inter-CU signaling indicating a configuration associated with the signals to be transmitted by the one or more aggressor downstream nodes based at least in part on the first inter-CU signaling. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may transmit, to a user equipment (UE), configuration information for both a first set of reference signals for a first beam sweeping procedure and a second set of reference signals for a second beam sweeping procedure. The UE may receive the first set of reference signals according to the configuration information, and may transmit a channel state information (CSI) report to the base station based on the received reference signals. After transmitting the CSI report, both the base station and the UE may autonomously update a transmission configuration indicator (TCI) state based on the CSI report (e.g., using a preferred transmit beam indicated in the CSI report). The base station may transmit on the preferred transmit beam, and the UE may receive on various candidate receive beams, the second set of reference signals.

    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for activation of configurations. Certain aspects provide a method for wireless communication by a first wireless node. The method generally includes receiving multiple configurations allocating resources for communication with one or more second wireless nodes, each of the multiple configurations being mapped to a configuration identifier; and receiving a message including the configuration identifier mapped to at least two of the multiple configurations, the message activating the at least two of the multiple configuration for the communication with the one or more second wireless nodes. The method may also include communicating with the one or more second wireless nodes using the at least two of the multiple configurations activated via the message.

    Abstract: The present disclosure provides for a configuration that enables an apparatus to determine beam pairs for full duplex communication based on a cross-link interference procedure. The apparatus determines a subset of receive beams based on a beam measurement process, where each receive beam is associated with a different antenna array panel. In some aspects, the apparatus performs a channel measurement process based on the subset of receive beams. The apparatus sweeps through transmitted sounding reference signals from a same transmit beam corresponding to each receive beam of an antenna array panel and receives the transmitted sounding reference signals incrementally through other receive beams associated with other antenna array panels. The apparatus measures a self-interference for at least one beam pair of the subset of receive beams based on a received sounding reference signal. The apparatus selects one or more beam pairs based on a self-interference measurement or a signal-to-interference-plus-noise ratio.

    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify a resource for wireless communication, the resource being in a first state where the resource is active for wireless communication and is inactive for a communication failure recovery procedure. The wireless device may determine that a communication failure has occurred during a first communication period. In some cases, one or more techniques for confirming the communication failure may be used to verify the failure. The wireless device may transition during a second communication period and based at least in part on the communication failure, the resource to a second state where the resource is inactive for wireless communication and is active for the communication failure recovery procedure. The wireless device may perform the communication failure recovery procedure using the resource transitioned to the second state.

    Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support priority based conflict resolution in full-duplex operations. In some cases, a wireless device may communicate one or more control messages scheduling a first message associated with a first transmission configuration indicator (TCI) state and scheduling a second message associated with a second TCI state, where at least a portion of the first message overlaps in time with the second message. In some cases, the wireless device may perform a conflict resolution procedure for the first message and the second message based on the first message at least partially overlapping in time with the second message and a conflict between the first TCI state and the second TCI state. Additionally, the wireless device may communicate at least the first message based on the conflict resolution procedure.
