Communication method and system for using time division duplex scheme and frequency division duplex scheme

The present invention relates to a frequency division multiplexing communication method and system using a hybrid scheme of the:: (Time Division Multiplexing TDD) scheme (FDD Frequency Division Multiplexing) scheme and a time division multiplexing. The present invention, in the communication method using a different communication method in a communication system, a base station uplink process for transmitting downlink information to a terminal through a frequency band of the first communication scheme for a downlink period, and the terminal for this purpose during the period comprises the step of transmitting the uplink information to the base station via the first communication method or a frequency band of the first communication system in a frequency band different from the first communication system in a frequency band.
