Abstract

The invention provides a data transmission method. The method comprises the steps that the backhaul state of a number of cells participating in multipoint transmission is acquired; the available backhaul rate of a number of cells is determined according to the backhaul state of a number of cells, and the available access resource of multipoint transmission of a number of cells is acquired; and according to the type and service requirement of multipoint transmission, the available backhaul rate of a number of cells, and the available access resource of multipoint transmission, the access resource of multipoint transmission of a number of cells is determined. According to the method, the efficiency of multipoint transmission is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for multipoint transmission in a wireless communication network. Background technique [0002] A traditional cellular network uses a cell as a basic unit, and a user terminal selects a specific cell as a serving cell, and the serving cell is responsible for user management and data transmission. The user terminal at the edge of the cell will be in an environment where the signal of the serving cell is weak and the interference of neighboring cells is strong. The traditional technology considers the signals of adjacent cells to be interference signals, and adopts interference coordination or interference cancellation technology to reduce the signals of adjacent cells and improve the signal quality of edge users. On the other hand, in order to improve system efficiency and provide high-speed services, the future cellular network will be a small and dense...
