Abstract: A method for cooperative communication in wireless communication systems is disclosed. The method for cooperative communication in a transmitter determines one or more signal transmission paths including one or more relay systems by considering the location of a terminal and the signal transmission delay time of the relay systems using the transmitter; and transmits signals through the determined transmission paths to the terminal. Therefore, the quality and data transmission rate of signals received through different paths are improved by allowing the signals to reach a CP(Cyclic Prefix) section and the terminal to perform normal demodulation.

Abstract: PURPOSE: A machine-to-machine communications supporting method and device are provided to support an efficient machine-to-machine communications service in a 3GPP(Third Generation Partnership Project) LTE(Long-Term Evolution)-based mobile communications system while maintaining compatibility with a legacy LTE terminal. CONSTITUTION: A machine-to-machine communications terminal(200) includes a control part(210) and a transmission/reception part(220). The control part detects the number of OFDM(Orthogonal Frequency Division Multiplexing) symbols occupied by a legacy PDCCH(Physical Downlink Control Channel) in a downlink channel sub-frame received from a base station through the transmission/reception part. The control part determines the number of OFDM symbols occupied by a legacy PDCCH based on extracted CFI(Control Format Indicator) information bits for a legacy terminal. The transmission/reception part receives a downlink sub-frame from a base station and provides to the control part. [Reference numerals] (210) Control part; (220) Transmission/reception part
