Classification: CPC H | IPC H

Claim 13:
14. A base station for performing communication through multiple bandwidth parts (BWPs), the base station comprising:
a transceiver; and
at least one controller coupled to the transceiver, and configured to transmit a terminal capability information request to a terminal, receive, in response to the request, terminal capability information comprising capability information related to multiple active BWP of the terminal, transmit 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 perform communication with the terminal through multiple BWPs activated based on the multiple active BWP configuration information, start a BWP inactivity timer corresponding to the activated multiple BWPs, 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.
