Abstract
Disclosed is a frequency hopping method in an OFDM system, comprising: (a) detecting a mutual interference degree between different cells, and determining whether to use different frequency hopping patterns between the cells for interference averaging according to the mutual interference degree interference degree; (b) determining a number P of the different frequency hopping patterns needed between all the cells in the system; (c) generating the frequency hopping patterns of more than the number P and allocating the generated frequency hopping patterns to each cell, the frequency hopping patterns having the same frequency collision times between two channels in the different frequency hopping patterns; and (d) frequency-hopping the channels in each cell according to the allocated frequency hopping pattern.
