Abstract:
1. A downlink Inter-Cell Interference Coordination (ICIC) method, comprising: obtaining, by an evolved NodeB (eNB), information about multiple carriers in a current cell; obtaining, by the eNB, according to the information comprising a frequency and bandwidth of each carrier of the multiple carriers, a downlink ICIC parameter corresponding to each carrier of the multiple carriers, wherein the obtaining the downlink ICIC parameter comprises: predicting, by the eNB, according to the frequency and bandwidth of each carrier of the multiple carriers, system performance indices that the multiple carriers can achieve under different configurations of downlink ICIC parameter combinations, wherein each downlink ICIC parameter in the downlink ICIC parameter combinations corresponds to each carrier of the multiple carriers, and obtaining, by the eNB, a downlink ICIC parameter combination whose system performance indices satisfy set system performance index thresholds from the different downlink ICIC parameter combinations; and sending, by the eNB, the downlink ICIC parameter corresponding to each carrier to a neighboring cell of the current cell so as to enable the neighboring cell to perform, according to the downlink ICIC parameter, downlink interference coordination with the current cell.
