Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A user equipment (UE), the UE comprising:
a transmitter;
a receiver;
a memory; and
a data processing system comprising one or more processors, wherein the UE is configured to:
based on measurements of reference signals that were transmitted using a first transmit (TX) beam, detect whether a beam failure has occurred; and
as a result of detecting that the beam failure has occurred, transmit at least a first beam failure message indicating that the UE has detected that the beam failure has occurred, wherein
the UE is configured to determine whether the beam failure has occurred by performing a process that 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.
