System and method of handling bandwidth part inactivity timer

A method of a base station, the method comprising:

• transmitting, to a user equipment (UE), first information of a timer associated with a beam failure recovery and second information of maximum count value associated with beam failure instance;
• receiving, from UE, a contention-free random access preamble for initiating a random access procedure for a beam failure recovery request;
• and
• transmitting, to the UE, physical downlink control channel (PDCCH) associated with a cell radio network temporary identifier (C-RNTI) of the UE,
• wherein the timer is started in response to identifying that a number of beam failure instances is greater or equal to the second information and the timer is stopped in response to identifying that the random access procedure is completed successfully.

A user equipment (UE) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• at least one processor coupled to the transceiver, the processor configured to:
• control the transceiver to receive first information of a timer associated with a beam failure recovery and second information of maximum count value associated with beam failure instance;
• identify a number of beam failure instances;
• identify whether the number of beam failure instances is greater or equal to the second information;
• start the timer associated with the beam failure recovery in response to identifying that the number of beam failure instances is greater or equal to the second information;
• control the transceiver to transmit a contention-free random access preamble for initiating a random access procedure for a beam failure recovery request;
• control the transceiver to receive physical downlink control channel (PDCCH) associated with a cell radio network temporary identifier (C-RNTI) of the UE;
• identify whether the random access procedure is completed successfully;
• and
• stop the timer in response to identifying that the random access procedure is completed successfully.
