Method and device for resource allocation

摘要

The embodiment of the present invention relates to the technical field of wireless communication, and particularly to a method and a device for resource allocation, which are used to solve the problem existing in the prior art that, when an inter-neighborhood interference coordination method is used to reduce interference, it often results in a low resource utilization rate in neighborhoods or a limitation on the transmission power, which wastes the hardware resources in a base station and increases power consumption. The method in the embodiment of the present invention comprises: at least two frequency sub-bands are determined in a carrier bandwidth, wherein the central frequencies of frequency sub-bands are different, and there is an overlapping area in the frequency domain between at least two frequency sub-bands from all frequency sub-bands; the determined frequency sub-bands are allocated to individual neighborhoods in a deployment area, and the frequency sub-band allocated to a neighborhood is used as the system bandwidth of that neighborhood. By using the method in the embodiment of the present invention, the inter-neighborhood interference in common uplink channels and common downlink channels is decreased effectively, and thus the limitation on transmission power in those neighborhoods is reduced, which increases the available signal transmission power in the neighborhoods to a certain extent and at the same time reduces the hardware costs of the base station and power consumption, without increasing the costs for network deployment.

1. A method for resource allocation, comprising:
determining at least two sub-bands in a carrier bandwidth, wherein central frequency points of respective sub-bands are different, and there is an overlapping area in a frequency domain between at least two sub-bands of all sub-bands; and allocating the determined sub-bands to respective cells in a deployment region, wherein each of the sub-bands is allocated to a respective cell and taken as a system bandwidth of that cell, the system bandwidth of that cell comprising all frequency resources of sub-bands allocated to that cell; wherein determining at least two sub-bands in the carrier bandwidth includes having at least six Physical Resource Blocks, PRBs, between central frequency points of sub-bands with consecutive serial numbers.
