Method for distributing resources between main service cell and coordinate cells

Abstract

The invention relates to a technique for realizing coordinate multipoint communication, in particular to a method for coordinating resource distribution between a main service cell and coordinate cells in a wireless cellular network. The method comprises that: user equipment receives reference signals sent by a plurality of cell base stations and selects a main service cell base station and coordinate cell base stations; according to the service rate requirement of the user equipment and feedback channel parameters, the main service cell base station negotiates with the coordinate cell base stations to select a transmission channel; and the main service cell base station negotiates with the coordinate cells to distribute coordination power for performing multipoint coordinate transmission. In the invention, based on the conventional cellular network architecture, computing complexity and signaling interaction amount are lowered by a method for optimizing negotiation by the direct negotiation between the main service cell base station and the coordinate cell base stations. Thus, limited frequency spectrum resources and power resources are used fully, interference is avoided effectively and the service quality at cell edges is improved.

Description

Method for resource allocation between main serving cell and cooperative cell technical field The invention relates to a technique for realizing coordinated multi-point communication, in particular to a method for resource allocation between a main serving cell and a coordinated cell in a wireless cellular network. Background technique Most of the commercial wireless network operators now adopt the cellular network architecture. The cellular network architecture has the characteristics of high spectrum utilization, strong adaptability, and good scalability. However, due to the structural characteristics of the cellular network itself, there are disadvantages of low useful signal strength and high interference power at the edge of the cell. Therefore, how to improve the network service quality at the cell edge is a hot issue in the current wireless communication development. The coordinated multi-point communication (Coordinated Multi-point, CoMP) technology is a key tec...
