Abstract: A wireless communications system in which real-time data and burst data can be mixedly transmitted, and a transmission band can be dynamically assigned according to a state of data transmission. A master station has a scheduler for determining a transmission band assignment including information about the transmission timing of the data, a transmission amount, and a station that is allowed to access. The scheduler regularly carries out scheduling, and optimizes the transmission band to be assigned dynamically according to the communication type of the data and a state of data transmission. The master station gives a transmission band assignment which is determined by the scheduler to each slave station. A transmitting station executes data transmission (access) to a receiving station based on the given transmission band assignment. The receiving station gives information about a state of data receiving to the master station, where the scheduler reflects this on scheduling.

Abstract: A communication system CS includes a plurality of communication stations and data communication is performed between any two communication stations, one is a transmitting station and the other is a receiving station. When any data for transmission is generated, the transmitting station transmits, to the receiving station, a reservation request packet for requesting bandwidth reservation. The receiving station reserves a bandwidth responding to the reservation request packet and then transmits a communication reservation packet to inform the transmitting station of the reserved bandwidth. The transmitting station creates a data packet and then transmits the created data packet through the informed bandwidth. The receiving station stores a valid period of the bandwidth reserved for the transmitting station, and voluntarily and repeatedly creates, for transmission, the communication reservation packet for the duration of the stored valid period.
