Abstract
A method and base station for dynamic adjustment of a carrier resource are disclosed. First, a cell-edge traffic volume of a local cell is detected; then, if the cell-edge traffic volume of the local cell is reduced, an idle primary subcarrier resource in the cell is released as a secondary subcarrier according to a degree of reduction of the cell-edge traffic volume and according to a multiple of a predetermined minimum granularity. With it, when the cell-edge traffic volume of the local cell is changed, the allocation of a primary subcarrier and a secondary subcarrier may be adjusted dynamically, which increases a utilization rate of a spectrum and ensures that carrier resources can be utilized properly and adequately.
