RESOURCE ALLOCATION METHOD AND BASE STATION

摘要

A resource allocation method and base station. The resource allocation method comprises: within a current scheduling period, determining priorities of users in a cell for sub-carriers in available frequency resources, and among the available frequency resources of the cell, allocating a corresponding available frequency resource for each user in the cell according to the priorities of all users for the sub-carriers, so that the frequency resources that can be used by the edge users cover all available frequency ranges of the cell. Therefore, when frequency selectivity fading occurs in the channel, a decline in communication quality caused by allocating carrier resources for the edge users in the limited frequency resources is avoided, the probability that the edge users use deeply fading frequency resources is reduced, and interruption in the communication process is decreased, thereby improving system throughput.

1. A resource allocation method, characterized in that the method comprises:
determining the priority of each user with respect to each subcarrier in the available frequency resources of the present cell during the current scheduling period; with respect to any unallocated subcarrier in the available frequency resources, sequentially executing the following operations: determining the user with the highest priority with respect to the subcarrier; when the user with the highest priority has not been allocated with sufficient carrier resources, allocating the subcarrier to the user with the highest priority, otherwise when other users with priority are present with respect to the subcarrier, allocating the subcarrier to said other users with priority.
