1. A method of a terminal, comprising:
receiving first configuration information on a carrier from a base station;
identifying some resource block(s) (RB(s)) among RBs constituting the carrier as a guard band;
receiving second configuration information from the base station, and determining a first time period and a second time period based on the second configuration information; and
performing communication with the base station based on a first RB group in the first time period and based on a second RB group in the second time period,
wherein the first RB group comprises RB(s) excluding RB(s) constituting the guard band among the RBs constituting the carrier, the second RB group comprises RB(s) including the RB(s) constituting the guard band among the RBs constituting the carrier, and the communication with the base station includes transmission of a data channel.
