摘要
A frequency band for communication between a base station and mobile stations is divided into a reverse-link and a forward-link bands. In each of these bands, carrier frequencies are defined in correspondence with sub frequency bands each having one of several bandwidths. To each of these bands of each mobile station, a sub frequency band with a bandwidth matching a data traffic rate is assigned in advance. Each mobile station spectrum-spreads a reservation packet and transmits the resultant packet by a prescribed carrier frequency corresponding to the reverse-link sub frequency band. The base station spectrum-spreads a response packet and transmits the resultant packet by a prescribed carrier frequency corresponding to the forward-link sub frequency band. Each mobile station spectrum-spreads a data packet by a spreading code for data traffic channel specified in the response packet and transmits the resultant packet by the reverse-link carrier frequency.
