Radio transmission method and apparatus

A control station for controlling a radio network having a plurality of communication stations, comprising:

• a controller for defining a transmission frame format having a defined frame period and consisting of a management information transmission region and an information transmission region;
• wherein said management information transmission region consists of a fixed length down-link management section and a station synchronous section;
• said station synchronous section for identifying each communication station in the radio network and having a variable length corresponding to the number of communication stations in the radio network;
• and
• a radio transmitter for sending and receiving signals having the defined transmission frame format.

A radio transmission network for radio transmission between a control station and a plurality of communication stations, comprising:

• said control station for controlling said radio transmission network, comprising:
• a first controller for defining a transmission frame format having a defined frame period and consisting of a management information transmission region and an information transmission region;
• wherein said management information transmission region consists of a fixed length down-link management section and a station synchronous section;
• said station synchronous section for identifying each communication station in the radio network and having a variable length corresponding to the number of communication stations in the radio network;
• and
• a first radio transmitter for sending and receiving signals having the defined transmission frame format;
• and
• at least one communication station controlled by said control station, comprising:
• a second radio transmitter for sending and receiving signals having the defined transmission frame format;
• and
• a second controller for transmitting a station synchronous signal identifying the communication station and included at a designated position in said station synchronous section.
