Claim 11:
12. A method performed by a user equipment (UE), the method comprising:
based on measurements of reference signals that were transmitted using a first transmit (TX) beam, the UE detecting that a beam failure has occurred; and
as a result of detecting that the beam failure has occurred, the UE transmitting a beam failure message indicating that the UE has detected that the beam failure has occurred, wherein the step of determining that the beam failure has occurred comprises:
determining whether a determined radio link quality value satisfies a condition; and
as a result of determining that the determined radio link quality value satisfies a condition, calculating C_new=C_old+x, wherein C_old is a counter value and x is a predetermined constant;
comparing C_new to a threshold; and
based on the comparing, determining whether the beam failure has occurred.
