摘要

Disclosed is a wireless communication system with communication stations that make information transmission therebetween by selecting a proper transmission rate under a communication environment where plural transmission rates coexist. In order for a transmission station for transmitting a packet to determine a transmission rate for transmission of subsequent packets, the system includes a first mode of determining a transmission rate fed back from the reception station as its transmission rate, a second mode of determining a transmission station independently regardless of a feedback of a transmission rate from the reception station, and a third mode of determining a transmissions rate while considering the transmission rate fed back from the reception station. In the first mode, the reception station feeds back a transmission rate that should be used in the transmission of the subsequent packets and sets up a transmission stop duration of the peripheral stations based on the transmission rate being fed back. In the second mode, the reception station sets up a transmission stop duration based on the transmission rate specified by the transmission station. In the third mode, the receiving feeds back a transmission rate data that should be used to transmit the subsequent packets to the transmission station and sets up a transmission stop duration of peripheral stations based on the default transmission rate specified by the transmission station.
