Patent ID: 8837412

Claim:
A method for allocating an edge frequency band resource, comprising: obtaining, through message interaction, usage information about an edge frequency band resource block of an adjacent mode; according to the usage information about the edge frequency band resource block of the adjacent mode and a characteristic resource block, determining an available edge frequency band resource block of a current mode for a next adjustment period, wherein the characteristic resource block is only used in its corresponding mode and the adjacent mode is a mode whose characteristic resource block is adjacent in frequency to the characteristic resource block of the current mode; and in the next adjustment period, allocating the determined available edge frequency band resource block of the current mode to each cell that corresponds to the current mode; wherein determining the available edge frequency band resource block of the current mode for the next adjustment period comprises: comparing usage information about an edge frequency band resource block of the current mode with usage information about the edge frequency band resource block of the adjacent mode; and among characteristic resource blocks that are adjacent to a characteristic resource block of the current mode, determining the available edge frequency band resource block of the current mode for the next adjustment period based on the comparison.
