Abstract: Embodiments of the present disclosure relate to failure recovery for serving cell. A terminal device detects a failure on a serving cell of the terminal device. If the beam failure is detected, the terminal device transmits information concerning the detected failure to a network device. The network device is associated with the serving cell. The terminal device disables further transmission of the information to the network device.

Abstract: The method includes performing at least one first monitoring of a power savings channel of a physical downlink control channel (PDCCH) for control information, the PDCCH being associated with at least one base station, the control information including a power saving downlink control information (PS-DCI) format, the control information providing an indication to start a timer for an ON duration of a discontinuous reception (DRX) cycle for a user equipment (UE) to monitor the PDCCH. The method further includes performing a random-access channel (RACH) procedure with the at least one base station based on the control information. The network node performs the method.

Abstract: A method of beam failure recovery for a serving cell is disclosed. In response to a beam failure on a first bandwidth part in a serving cell, a first device detects a first candidate beam associated with the first bandwidth part (310). In response to a failure of detecting the first candidate beam, the first device switches from the first bandwidth part to a second bandwidth part in the serving cell. The second bandwidth part is configured with at least one reference signal identifying a second candidate beam for recovery from the beam failure (320). The first device detects the second candidate beam based on the at least one reference signal (330). In response to a success of detecting the second candidate beam, the first device transmits information concerning the second candidate beam to a second device for the recovery from the beam failure (340).

Abstract: A radio network element includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the radio network element to: configure a quasi-co-location-type information entry included in a transmission configuration indication state (S604) for a downlink transmission beam between the radio network element and a user equipment based on at least one beam report, the at least one beam report including at least one transmission parameter for the downlink transmission beam, and the quasi-colocation-type information entry being indicative of one or more sources of inter-beam-interference on the downlink transmission beam at the user equipment; and transmit the transmission configuration indication state including the quasi-co-location-type information entry to the user equipment (S606).
