Abstract: Communication operations are optimally conducted by applying space-division multiple access in which wireless resources on a spatial axis are shared among a plurality of users. By applying an RD protocol to a communication system that conducts space-division multiple access, spatially multiplexed frames in a TXOP are made more efficient. By specifying a frame length for reverse direction frames with reverse direction permission information and having respective transmitters of reverse direction frames make their frame lengths uniform while respecting the specification, AGC operation stabilizes. Also, a transmit start time for reverse direction frames can be specified by reverse direction permission information, and respective transmitters of reverse direction frames can transmit frames at the same time while respecting the specification.

Abstract translation: 通过应用空分多路访问来最佳地进行通信操作，其中空间轴上的无线资源在多个用户之间共享。 通过将RD协议应用于进行空分多址的通信系统，使TXOP中的空间复用帧更有效。 通过指定具有反向许可信息的反向帧的帧长度并且具有相反方向帧的各个发射机使其帧长度在遵守规范的情况下是均匀的，则AGC操作稳定。 此外，反方向帧的发送开始时间可以通过反向许可信息来指定，并且反方向帧的各个发送机可以在遵循说明书的同时发送帧。
