A method for establishing reverse traffic channels in a multi-carrier wireless communication system includes: an access terminal (AT) sending a carrier request message to an access network (AN), said carrier request message carrying a reverse carrier request indicator indicating the number of reverse carrier links required by AT (S11); AN sending a traffic channel assignment message carried with a reverse traffic channel information to AT (S12); AT establishing reverse traffic channels according to the traffic channel assignment message, and sending a pilot and data rate control signal (S13); AT sending a channel establishment complete information over the reverse traffic channel (S15); and transferring data by using said channel (S16). AT requests the number of reverse carriers from AN on its own initiative without any modification to the previous messages, thus backward compatibility is maintained. AT can dynamically and flexibly request reverse carriers according to its own demand. |
