Abstract:
1. A wireless communication system for providing a service in time and frequency division duplexing modes, the system comprising: a wireless terminal for transmitting a duplexing mode determination factor when a call is established, receiving a command for at least one of a time division duplexing mode and a frequency division duplexing mode for reverse transmission, determining an access method and a hopping mode according to each of the time and frequency division duplexing modes, and establishing a forward channel and a reverse channel according to the set time or frequency division duplexing mode for reverse transmission to perform communication; and a base station for receiving the duplexing mode determination factor from the wireless terminal when the call is established, setting the at least one of the time division duplexing mode and the frequency division duplexing mode for the reverse transmission, setting a time division duplexing mode for forward transmission according to the received duplexing mode determination factor, determining a frequency hopping mode and a multiple access mode, and communicating with the wireless terminal according to the determined frequency hopping mode and the determined multiple access mode.
