Space-division multiple access, in which a plurality of users share a radio resource on the spatial axis, is applied to perform suitable communication operations. RD protocol is applied to a communication system that performs the space-division multiple access, thereby making the space multiple frames in TXOP further effective. Backward permission information is used to specify the frame length of backward frames, and the backward frame transmission sides comply with the specification to equalize the frame lengths, thereby stabilizing the AGC operations. Moreover, the backward permission information is used to specify a backward frame transmission start time, and the backward frame transmission sides comply with the specification, thereby achieving concurrent transmissions. |
