Claim 0:
1. A method performed by a wireless device in a wireless communication system, the method comprising:
receiving a Bandwidth Part (BWP) configuration including information on (i) multiple BWPs, and (ii) a priority for the multiple BWPs;
activating a first BWP and a second BWP among the multiple BWPs;
performing Radio Link Monitoring (RLM) procedure only for the first BWP which has been determined as a primary active BWP;
initiating a first random access procedure for the first BWP;
determining to change the primary active BWP from the first BWP to the second BWP upon detecting a BWP failure for the first BWP, wherein the second BWP is selected based on the information on the priority for the multiple BWPs;
stopping the first random access procedure for the first BWP, upon detecting the BWP failure for the first BWP;
performing RLM procedure for the second BWP which is selected as the primary active BWP;
initiating a second random access procedure for the second BWP, after changing the primary active BWP from the first BWP to the second BWP; and
transmitting a BWP failure information informing the BWP failure for the first BWP via the second BWP, after completing the second random access procedure.
