Abstract: Wireless communications systems and methods related to resolving conflicts between full-duplex signals are provided. A base station may schedule resources for a UE or plurality of UEs. The scheduled resources may include simultaneous uplink and downlink resources. The scheduled resources may utilize beams which if used would cause excessive interference. As such, a conflict resolution action may be performed by the BS and UE to mitigate any problems arising from using both incompatible beams simultaneously. Conflict resolution actions may include dropping one of the signals. Conflict resolution actions may include and changing one or both beam configurations for the signals. Conflict resolution actions may be based on predetermined rules or may be based on an indication from the base station.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for DCI content and modified/enhanced codebook Type 3 HARQ PUCCH content for deferred SPS PUCCH ACK/NACK. In aspects, a UE may receive, from a base station, DCI including a request for HARQ-ACK feedback associated with at least one resource that is unavailable. The HARQ-ACK feedback may be based on one or more one-shot HARQ-ACK codebooks including one or more bits. The UE may transmit, to the base station, the HARQ-ACK feedback associated with the at least one resource that is unavailable, where the HARQ-ACK feedback includes the one or more one-shot HARQ-ACK codebooks including the one or more bits.

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-readable media, for leveraging a resource management protocol under an integrated access and backhaul (IAB) framework for power savings. In some aspects, a first node (such as an IAB node) may receive resource management information from a second node (such as an IAB donor). The resource management information may indicate an unavailable type of resource management configuration for the first resource associated with the first node. The first node may schedule a power save mode during the first resource having the unavailable type of resource management configuration for power savings. The first resource may be a time domain resource, a frequency domain resource, or a spatial domain resource. In some aspects, the first node may restrict both non-exempt and exempt communications during the first resource when the first node is in the power save mode.

The plurality of downlink data transmissions are monitored across the plurality of slots. At least one HARQ feedback scheme for acknowledging the plurality of downlink data transmissions is determined. HARQ feedback for the plurality of downlink data transmissions is provided in accordance with the at least one HARQ feedback scheme.

Abstract: Certain aspects of the present disclosure provide enhancements to enable per transmission reception point (per-TRP or per beam group)-based beam failure recovery, and more particularly, techniques for TRP-specific beam failure recovery request (BFRQ). A method that may be performed by a user equipment (UE) includes communicating using beams associated with at least two beam groups, each associate with one of the TRPs, detecting a beam failure in a first one of the beam groups, and transmitting an indication of a BFRQ specific to a beam group in which the beam failure was detected.

Abstract: Techniques to enable and provide beam failure recovery (BFR) operation for discontinuous reception (DRX) modes with wakeup signal (WUS) monitoring are described. DRX mode operation may be altered based on a BFR procedure implemented by a user equipment (UE). DRX mode operation may be altered for allowing a UE to start a DRX active time after transmitting a BFR request signal of a BFR procedure. Additionally or alternatively, DRX mode operation may be altered for allowing a UE to start an ON duration timer for a next DRX cycle after transmitting a BFR request signal of a BFR procedure. In another example, DRX mode operation may be altered for allowing a UE to monitor a BFR search space set regardless of DRX status, after transmitting a BFR request signal for a BFR procedure. Other aspects and features are also claimed and described.
