Classification: CPC H | IPC H

Claim 7:
8. A method, performed by a base station, of performing communication through multiple bandwidth parts (BWPs) in a wireless communication system, the method comprising:
transmitting a terminal capability information request to a terminal;
receiving terminal capability information comprising capability information related to multiple active BWP of the terminal in response to the request;
transmitting multiple active BWP configuration information for configuring activation of multiple BWPs of the terminal based on the capability information related to multiple active BWP of the terminal; and
performing communication with the terminal through multiple BWPs activated based on the multiple active BWP configuration information,
starting a BWP inactivity timer corresponding to the activated multiple BWPs; and
in case that communication of data transmitted and received through each of the activated multiple BWPs succeeds, starting the BWP inactivity timer,
wherein, in case that the BWP inactivity timer expires, at least one of an operation of stopping using all activated BWPs except an initial BWP and performing a random access procedure through the initial BWP, an operation of performing transition to an idle mode, an operation of performing transition to an inactive mode, a connected discontinuous reception (DRX) (CDRX) operation, a radio link failure (RLF) declaration operation, and a beam failure recovery operation is performed.
