User equipment and beam failure recovery method
View Patent ↗The present invention provides user equipment and a beam failure recovery method. The beam failure recovery method for user equipment (UE), includes: receiving indication of beam failure instance; accumulating the number of received indications so as to obtain an accumulative value; initiating a beam failure recovery procedure when the accumulative value is greater than a first threshold; and skipping processing the received indication of beam failure instance during the beam failure recovery period. Thus, it is possible to eliminate false beam failures.
1. A method performed by user equipment, comprising:
receiving a beam failure instance indication from lower layers;
incrementing a counter for the beam failure instance indication by 1, on the basis of a determination that the beam failure instance indication has been received from lower layers;
resetting the counter to 0 if no beam failure instance indication is received within a time threshold; and
initiating a random access procedure if the counter exceeds a specific value.
2. A user equipment, comprising;
a processor; and
a memory in electronic communication with the processor, wherein, instructions stored in the memory are executable to:
receive a beam failure instance indication from lower layers;
increment a counter for the beam failure instance indication by 1, on the basis of a determination that the beam failure instance indication has been received from lower layers;
reset the counter to 0 if no beam failure instance indication is received within a time threshold; and
initiate a random access procedure if the counter exceeds a specific value.
