transmission and reception of a plurality of radio communication frames, wherein
said plurality of radio communication frames includes successive radio communication frames, at least one of which is a radio communication frame including an effective symbol to which a cyclic prefix and a non-transmission interval are added.
2. The radio communication system according to claim 1, wherein
in said radio communication frame, said non-transmission interval is added temporally before said cyclic prefix.
3. The radio communication system according to claim 1 or 2, wherein
the temporal length of said non-transmission interval is set based on the speed of transient response by equipment to transmit or receive said radio communication frames.
