1. A communication method in a communication system, the method comprising the steps of:
- transmitting, by a base station, downlink information to a terminal through a frequency band of a first communication scheme for a downlink period; and
transmitting, by the terminal, uplink information to the base station through the frequency band of the first communication scheme or a frequency band of a second communication scheme that is different from the frequency band of the first communication scheme, for an uplink period.

Abstract
A communication method in a communication system includes a base station that transmits downlink information to a terminal through a frequency band of a first communication scheme for a downlink period. The terminal transmits uplink information to the base station through the frequency band of the first communication scheme or a frequency band of a second communication scheme that is different from the frequency band of the first communication scheme, for an uplink period.
