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, by one or more processors, available frequency resources within a present cell wherein the available frequency resources comprise one or more subcarrier frequency resources; dividing, by the one or more processors, the one or more subcarrier frequency resources into at least one primary subcarrier frequency band and at least one auxiliary subcarrier frequency band, wherein transmission power of each primary subcarrier frequency band is higher than transmission power of each auxiliary subcarrier frequency band; determining, by the one or more processors, for each of a plurality of users, a priority for each one of the one or more subcarrier frequency resources during a current scheduling period; determining, by the one or more processors, for each user, whether the user is a center user, and for each center user, lowering the priority of the center user with respect to the at least one primary subcarrier frequency band; determining a service grade QoS for each user; and for each user, obtaining a preset priority adjustment coefficient corresponding to the determined QoS, and adjusting each priority for each one of the one or more subcarrier frequency resources of the user using the obtained preset priority adjustment coefficient; determining, by the one or more processors, unallocated subcarrier frequency resources in the one or more subcarrier frequency resources; and for each unallocated subcarrier frequency resource, sequentially executing, by the one or more processors: determining a highest priority user with respect to the unallocated subcarrier frequency resource; and when the highest priority user has not been allocated with sufficient carrier resources, allocating the unallocated subcarrier frequency resource to the highest priority user, otherwise allocating the unallocated subcarrier frequency resource to next highest priority user who has not been allocated with sufficient carrier resources.
