Method and base station for dynamic adjustment of carrier resource

摘要

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.

1. A method for dynamic adjustment of a carrier resource comprising:
detecting a cell-edge traffic volume of a local cell; comparing the cell-edge traffic volume to a first threshold value and a second threshold value to determine a degree of reduction of the cell-edge traffic volume; releasing an idle primary subcarrier resource in the local cell as a secondary subcarrier according to the degree of reduction of the cell-edge traffic volume and according to a multiple of a predetermined minimum granularity when the cell-edge traffic volume of the local cell is reduced; sensing a primary subcarrier of a neighboring cell through a predetermined sensing algorithm, wherein the primary subcarrier is obtained through division, and acquiring an idle primary subcarrier resource in the neighboring cell; and receiving a result of sensing a primary subcarrier of a neighboring cell, wherein the primary subcarrier is obtained through division, and wherein the result is reported by a terminal in a cell through a predetermined sensing algorithm, and deciding, according to the sensing result and through a fusion algorithm, an idle primary subcarrier resource of the neighboring cell.
