1. A transmission control method in which a radio transmission access among a plurality of communication stations is controlled by a control station, the transmission control method comprising the steps of: standardizing a frame period based on a synchronizing signal transmitted by a predetermined station from among the plurality of communication stations; setting a management data transmission area and data transmission area within said frame period; disposing a plurality of slots in said management data transmission area; and transmitting slot-using-situation data relative to each communication station or relative to said control station at said data transmission area in said management data transmission area. 2. The transmission control method as claimed in claim 1, wherein interference-disturbance-situation data from other systems at each slot also is transmitted in said management data transmission area together with said slot-using-situation data. 3. The transmission control method as claimed in claim 1, wherein said control station allocates the plurality of slots among said plurality of communication stations in an overlapping fashion in a range in which said plurality of slots will not interfere with a radio transmission in order to effect radio transmission among a plurality of other communication stations. 4. The transmission control method as claimed in claim 1, wherein each of said plurality of communication stations receives a respective transmission signal in one of said plurality of slots allocated thereto, judges whether said transmission signal can be decoded, and reports a judged result to said control station. 5. The transmission control method as claimed in claim 1, wherein said each slot-using situation is managed by each communication station in a distributed fashion. 6. A transmission apparatus in which communication is effected under access control from a predetermined control apparatus, said transmission apparatus comprising: timing setting means for setting a frame period based on a predetermined synchronizing signal, for setting a management data transmission area and a data transmission area within said frame period, and for setting a plurality of slots in said management data transmission area; transmission means for transmitting slot-using-situation data of its own station in said management data transmission area and also transmitting data in a slot of the data transmission area allocated by said control apparatus; and reception means for receiving data in the slot of the data transmission area allocated by said control apparatus. 7. The transmission apparatus as claimed in claim 6, wherein said transmission means transmits interference-disturbance-situation data from other systems in said management data transmission area together with said slot-using-situation data. 8. The transmission apparatus according to claim 6, further comprising judgment means for judging whether data of each slot received by said reception means can be decoded and wherein judged result data of said judgment means is transmitted in said management data transmission area by said transmission means.
