    Abstract: Wireless communication systems and methods related radio link failure monitoring and handling in full-duplex communications are provided. A user equipment communicates, with a base station, in a full-duplex mode using a first uplink beam and a first downlink beam. The user equipment detects a beam failure of at least one of the first uplink beam or the first downlink beam. The user equipment determines whether the beam failure is associated with self-interference in the full-duplex mode. The user equipment determines, based at least in part on the determination that the beam failure is associated with the self-interference in the full-duplex mode, to refrain from declaring a radio link failure.

  • BEAM FAILURE DETECTION
    Publication number: 20210410221
    Abstract: Aspects relate to detecting beam failure. A beam failure in a full-duplex communication scenario may be detected based on a reference signal measurement. For example, a user equipment (UE) may measure a downlink reference signal transmitted by a base station and/or an uplink reference signal transmitted by the UE and derive a quality parameter based on one or both of these measurements. If the quality parameter indicates a beam failure, the UE may generate an indication that one or more of the beams monitored by the UE have failed.

  • BEAM FAILURE HANDLING
    Publication number: 20210409097
    Abstract: Aspects relate to reporting beam failure. Upon detecting a beam failure, a user equipment (UE) may transmit a beam failure recovery request to a base station. If the uplink is working, the UE may transmit the beam failure recovery request via uplink signaling (e.g., via a physical uplink control channel or a physical uplink shared channel). If the uplink is not working or if the beam failure is due to downlink quality degradation, the UE may transmit the beam failure recovery request via a random access channel (RACH) message.
