Classification: CPC H | IPC H

Claim 10:
11. A method for receiving a signal, performed by a base station operating in an unlicensed band, the method comprising:
transmitting, to a terminal, first configuration information of a carrier including a first set of resource blocks (RBs), the carrier including guard band(s) and subbands;
transmitting, to the terminal, second configuration information for configuring location(s) of the guard band(s), the guard band(s) being a first subset of RBs belonging to the first set, the subbands being a second subset of RBs belonging to the first set;
transmitting, to the terminal, third configuration information for configuring a bandwidth part including one or more subbands among the subbands, the bandwidth part belonging to the carrier; and
receiving a signal from the terminal using a third subset of RB(s) of the bandwidth part,
wherein each of the guard band(s) is composed of zero or more consecutive RB(s) in the first subset, and a frequency location of the consecutive RB(s) of each of the guard band(s) is determined based on information related to a starting RB and a number of RB(s) of each of the guard band(s) configured by the second configuration information.
