1. A communication control method for controlling an access of radio communications among a plurality of communication stations by a control station, comprising the steps of:
- defining a frame period by a synchronizing signal transmitted from a predetermined station;
setting a management data transmission area in said frame period; and
arranging in said management data transmission area a plurality of time slots assigned to said plurality of communication stations, wherein each of said plurality of time slots of said management data transmission area contains data on a communication condition of a respective one of said plurality of communication stations, and each of said plurality of communication stations transmits on an assigned time slot of said plurality of time slots of said management data transmission area said data on said communication condition and receives data sent from an other communication station on an other time slot of said management data transmission area.

Abstract
A communication control method and a communication system, in which the transmission efficiency, in a network system is improved in the case where the communication in the network system is controlled by a control station. A management data transmission area is set in a frame period, and a plurality of slots are arranged in the management data transmission area. Data on the communication condition of each station are individually transmitted by each of a plurality of communication stations or the control station in each of the slots.

7. A transmission unit including a plurality of communication stations for carrying out communications under a control of a predetermined control unit, comprising:
-
timing setting means for setting a frame period based on a predetermined synchronizing signal and for setting a management data transmission area having a plurality of time slots assigned to said plurality of communication stations in said frame period;
receiving means for receiving a signal transmitted from said plurality of communication stations in each respective time slot of said management data transmission area; and
transmission means for transmitting data on a receiving condition of each of said plurality of communication stations, wherein each of said plurality of time slots of said management data transmission area contains data on a communication condition of a respective one of said plurality of communication stations, and each of said plurality of communication stations transmits on an assigned time slot of said plurality of time slots of said management data transmission area said data on said communication condition and receives data sent from an other communication station on an other time slot of said management data transmission area. - View Dependent Claims (8, 9, 10, 11, 12)
