Abstract: Methods, systems, and apparatuses for wireless communications are described. Stations operating within a system may have a primary radio and a wakeup or low-power radio. Access points (APs) may send indications receivable by the wakeup radio to alert a station of a pending data transmission for the station. APs may transmit synchronization beacons for wakeup radios of the stations, and the transmission timing for the synchronization beacons may be adapted based on operating conditions of one or more stations. For example, an AP may skip transmissions of a synchronization beacon or may adapt the frequency of synchronization beacon transmissions based on various operating conditions or factors. Stations may report certain information about operating conditions or capabilities that may be used to adapt synchronization beacon transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, a configuration indicating a channel quality threshold that the UE may use to identify an interference-based beam failure indicator type. The UE may receive a reference signal for performing one or more signal measurements in accordance with the configuration. Based on the one or more signal measurements and the channel quality threshold, the UE may report an indication of the type of beam failure indicator to the base station.

Abstract: Methods, systems, and devices for sidelink assisted cross-link interference (CLI) determination are described. In some examples, a first wireless device may perform a first measurement of a sidelink message received from a second wireless device. As such, the first wireless device may transmit, to a base station, a report indicating that the second wireless device is estimated to be within a defined proximity of the first wireless device based at least in part on the first measurement satisfying a threshold. In some examples, the first wireless device may receive a control message, from the base station, scheduling transmission of a message between the base station and the first wireless device in a frequency resource in response to the report that the second wireless device is estimated to be within the defined proximity of the first wireless device.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating an uplink gap. The UE may transmit a reference signal in the uplink gap. The UE may perform at least one of a self-interference measurement or a beam pair calibration for full-duplex communication based at least in part on the reference signal. Numerous other aspects are described.

Abstract: Techniques and apparatus for providing hybrid automatic repeat request (HARQ) feedback for multiple physical downlink shared channel (PDSCH) transmissions are described. One example technique involves receiving downlink control information (DCI) scheduling a plurality of downlink data transmissions across a plurality of slots. 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: This disclosure provides systems, methods, and devices for wireless communication that support prioritization of reference signal measurement reports. In a first aspect, a UE measures a reference signal, determines that a trigger condition for transmission of a first report is met based on measurement of the reference signal, and transmits the first report on a resource on which the first report and a second report overlap based on priorities of the first report and the second report. Other aspects and features are also claimed and described.
