Abstract
A communication method performed by a User Equipment (UE) configured with a Discontinuous Reception (DRX) operation includes the UE initiating a Random Access (RA) procedure for Beam Failure Recovery (BFR) on a Special Cell (SpCell) after detecting a beam failure event on the SpCell, and transmitting a BFR Medium Access Control (MAC) Control Element (CE) on the SpCell. The BFR MAC CE indicates the beam failure event for the SpCell. The communication method further includes the UE determining a period of time as a DRX Active Time for the UE. The beginning of the period of time is determined by a first time at which the UE transmits the BFR MAC CE on the SpCell. The end of the period of time is determined by a second time at which the UE receives a BFR Response (BFRR) from the SpCell.
