Abstract:
1. A method for multiplexing frequency hopping in an Orthogonal Frequency Division Multiple Access (OFDMA) system, the method comprising: transmitting, by a transmitter, channel information of a Distributed Resource CHannel (DRCH) to a receiver over a Forward link Secondary Broadcast Control CHannel (F-SBCCH); and calculating, by the receiver, the number of DRCHs based on the channel information of the DRCH included in the F-SBCCH, extracting the number and positions of slots for global hopping and local hopping using the calculated number of DRCHs, frequency-hopping and time-multiplexing a reverse channel on the slot for global hopping and the slot for local hopping based on the extracted number and positions of slots, and transmitting the frequency-hopped and time-multiplexed reverse channel to the transmitter.
