Resource allocation method, base station and system

Abstract

The present invention relates to the technical field of communications. Disclosed are a resource allocation method, a base station and a system. The method is applied to a serving cell and an interference cell, the serving cell and the interference cell are configured with the same parameters, and the parameters comprise at least a PCI. In the method, time-frequency resources are allocated to all UEs in the serving cell at a subframe time point at which the serving cell can allocate time-frequency resources to users, and an obtained first allocation result is sent to the interference cell; time-frequency resources are allocated by the interference cell to non-edge UEs in the interference cell according to the first allocation result; time-frequency resources are allocated by the interference cell to all UEs in the interference cell at a subframe time point at which the interference cell can allocate time-frequency resources to users, and an obtained second allocation result is sent to the serving cell; and time-frequency resources are allocated by the serving cell to non-edge UEs in the serving cell according to the second allocation result. Besides, because there is no need to arrange an additional centralized control node to allocate video resources to user equipments, the efficiency of resource allocation is high.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a resource allocation method, base station and system. Background technique [0002] With the development of communication technology, the area covered by communication network is getting wider and wider. Wherein, the area covered by each base station is called a physical cell, and the physical cell to which the user equipment belongs is called a serving cell. When the user equipment is located at the edge of the serving cell, signal quality received by the user equipment will be poor due to signal attenuation and interference from adjacent interfering cells. In order to solve the above problems, the serving cell and neighboring cells jointly transmit signals to the user equipment to improve the signal quality received by the user equipment. Wherein, when performing joint transmission, it is necessary to allocate time-frequency resources to user equipments in...

AI Technical Summary

Problems solved by technology

[0005] Since a centralized control node needs to be set up to allocate the time-frequency resources of user equipment in all physical cells in the SFN, when there are many physical cells in the SFN, there will be more corresponding user equipment, so that when allocating user equipment When the frequency resources are used, more hardware resources are occupied

However, hardware resources are usually limited to a certain extent, which leads to limited physical cells that can be merged by SFN cells.

Therefore, resource allocation is less efficient
