The invention discloses a frequency resource coordination method which includes that a network side assesses the frequency selectivity degree of cells; and the network side opens or closes an inter-cell interference elimination technique (ICIC) algorithm. The invention further discloses a frequency resource coordination system correspondingly. Due to the fact that the ICIC algorithm is closed when current cell frequency is strong in selectivity, gain produced by a scheduling algorithm is used fully, interference among the cells is relieved through the ICIC algorithm, an influence on the frequency selectivity scheduling gain from the ICIC algorithm is reduced, and therefore frequency selectivity scheduling gain is guaranteed.
