ABSTRACT:
A multiple access method in a wireless communication system using a plurality of multiple access techniques is provided. When a call is established with a wireless terminal, the terminal transmits a duplexing mode determination factor to the base station to set a time or frequency division duplexing mode for reverse transmission and determine access and hopping modes according to each of the division duplexing modes, and establishes forward and reverse channels according to the set time or frequency division duplexing mode for reverse transmission to communicate with the base station. The base station receives the duplexing mode determination factor from the terminal, sets a time or frequency division duplexing mode for reverse transmission and sets a time division duplexing mode for forward transmission based on the received factor, and determines frequency hopping and multiple access modes to communicate with the terminal according to the determined frequency and multiple access modes.
