摘要

We have possessed the smart antenna, as for method and the device in order sending and receiving to do the data, 1st WTRU antenna request (RFA) includes the step which transmits the frame to 2nd WTRU the plural radio transmitter-receivers (WTRU) in the radio communication system which it has. Although 2nd WTRU receives the RFA frame, receives data frame transmission the desirable antenna is decided. 1st WTRU transmits the data frame on the desirable antenna.
