Radio transmission method and radio transmission apparatus

A radio transmission apparatus which serves as a control station of a network when a plurality of transmission apparatus form said network to transmit information among a plurality of other communicating stations, said radio transmission apparatus comprising:

• communication processing means for transmitting and receiving a radio signal;
• station synchronizing setting means for transmitting a synchronizing signal which determines a frame period using said communication processing means, designating a management information transmitting field within said frame period and setting a station sync transmit/receive interval during which communicating stations forming said network transmit and receive information within said management information transmitting field;
• and
• down-link control information transmitting means for transmitting down-link control information for notifying a specific communicating station which transmits during said station sync transmit/receive interval.

A radio transmission apparatus for communicating information with a plurality of other communicating stations in a network formed by a plurality of transmission apparatus, said radio transmission apparatus comprising:

• communication processing means for transmitting and receiving a radio signal;
• frame period determining means for receiving a synchronizing signal determining a frame period using said communication processing means and determining the frame period;
• management field specifying means for specifying a management information transmitting field within said frame period;
• down-link management information receiving means for designating a communicating station from which information is transmitted at a designated position within said management information transmitting field;
• and
• transmitting and receiving means for transmitting and receiving information based on a designation of said down-link management information.
