6. A method for wireless communications, including:
generating a configuration for beam failure detection and recovery operation of a user equipment and contain the configuration in a radio resource control signal to be provided to the user equipment; and
generating a beam failure recovery request response in response to receiving a beam failure recovery request from the user equipment,
wherein the configuration for beam failure detection and recovery operation includes timing information for beam quality evaluation,
wherein the timing information for beam quality evaluation comprises information on a duration of beam quality evaluation before beam failure is detected,
wherein the configuration for beam failure detection and recovery operation further includes information for selecting a candidate beam as a switching target,
wherein the information for selecting the candidate beam as the switching target comprises a Reference Signal Receiving Power (RSRP) threshold for selecting the candidate beam,
wherein a currently serving beam is determined to have failed by the user equipment, in a case that a number of events that the beam quality is detected by the user equipment is below a first threshold in the duration exceeds a predetermined value, and a candidate beam is then selected by the user equipment as a switching target, and
wherein the candidate beam selected by the user equipment is a beam with a RSRP that is higher than the RSRP threshold,
wherein the method further comprises receiving the information about the selected candidate beam in the beam failure recovery request from the user equipment.
