    摘要： The present invention discloses a downlink interference management method, applied to interference coordination between a serving base station of a cell serving at least one first user equipment and a neighboring-cell base station of the cell, including: obtaining, by the serving base station, downlink interference overload information, where the downlink interference overload information is used to indicate an interfered-with transmission resource of the first user equipment; and sending, by the serving base station, the downlink interference overload information to the neighboring-cell base station, so that the neighboring-cell base station performs interference coordination on the transmission resource. The downlink interference overload information sent by the serving base station to the neighboring-cell base station may instruct the neighboring-cell base station to perform interference coordination on the interfered-with transmission resource.

    摘要： Embodiments of the present invention provide a method and an apparatus for dynamic spectrum management. The method includes: determining a reusable spectrum for one of multiple cell links in a network according to co-frequency indication information, where the co-frequency indication information is used to indicate reusable levels of spectrums of other cell links for each cell link in the multiple cell links; and updating a spectrum configuration of the one of the multiple cell links by using the reusable spectrum of the one of the multiple cell links. By determining a reusable spectrum for a specific cell link according to co-frequency indication information, embodiments of the present invention can locally adjust the spectrum configuration of the specific cell link, thereby reducing a spectrum configuration overhead while increasing network capacity and reducing inter-cell interference.
