To provide a radio transmission method and a radio transmission apparatus capable
of performing a highly-efficient radio transmission depending on the number of
communicating stations, a predetermined frame period is prescribed, a management
information transmitting field being provided within the frame period, a station
sync transmit/receive interval being provided within the management information
transmitting field and an arbitrary communicating station being designated to transmit
a station sync at plural frame period intervals during the station sync transmit/receive
interval. Thus even if only the station sync transmitting area corresponding to
the number which is less than the number of communicating stations forming a network
exists within one frame, the station sync can be transmitted and received.
