Abstract

The present invention relates to a method and system for supporting an interference-free relay between short distance picocells. The present invention system supports a relay between picocells based on a network cycle including a plurality of control frames and comprises a master device which receives at least one of the plurality of control frames allocated thereto as a synchronous control frame and then transmits the synchronous control frame at an orthogonal hopping frequency; a synchronous relay device which receives the synchronous control frame to remain synchronous with the master device, receives the allocated synchronous control frame out of the plurality of control frames as a relay synchronous control frame and then transmits the relay synchronous control frame at another orthogonal hopping frequency free of interference; and at least one slave device which receives the relay synchronous control frame in a region where the synchronous control frame of the master device has not been received, so as to remain synchronous with the synchronous relay device. Advantages of the present invention are that the relay is supported per se without an additional repeater and there is no collision between signals in the relay.
