Abstract:
1. A method of transmitting cyclic prefix length information if different cyclic prefix lengths are used for a first system region for a first communication system and a second system region for a second communication system, the method comprising: transmitting, by a transmitting end, a superframe header to a receiving end, wherein the superframe header includes cyclic prefix length information which comprises a first cyclic prefix length and an indicator, wherein the indicator indicates whether the transmitting end supports a first communication system and a second communication system, wherein a fixed cyclic prefix length is applied up to the superframe header of the first system region of the first communication system, and the first cyclic prefix length is applied to a remaining region of the first system region, and wherein an idle time period is immediately followed by the superframe header when the fixed cyclic length and the first cyclic prefix length are different from each other.
