Claim 7:
8. A wireless device in a wireless communication system comprising:
a transceiver;
a memory; and
at least one processor operatively coupled to the transceiver and the memory, and configured to:
activate a first BWP and a second BWP among the multiple BWPs;
perform Radio Link Monitoring (RLM) procedure only for the first BWP which has been determined as a primary active BWP;
initiate a first random access procedure for the first BWP;
determine 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;
stop the first random access procedure for the first BWP, upon detecting the BWP failure for the first BWP;
perform RLM procedure for the second BWP which is selected as the primary active BWP;
initiate a second random access procedure for the second BWP, after changing the primary active BWP from the first BWP to the second BWP; and
transmit a BWP failure information informing the BWP failure for the first BWP via the second BWP, after completing the second random access procedure.
