Abstract

A method for coordinating the resources between cells is used to implement the coordination of the resources of space, time, frequency and power between cells. The method includes the processes that: the wireless node of the current cell determines the wireless nodes of multiple neighbor cells adjacent to itself (S102); the wireless node of the current cell interacts with the determined wireless nodes of multiple neighbor cells adjacent to itself about the resource coordination information (S104); based on the interaction of the resource coordination information, the wireless node of the current cell determines the resources which will be used during the specific time interval in the future by itself and the wireless nodes of multiple neighbor cells (S106).

Description

technical field [0001] The present invention relates to the field of communication, in particular to a resource coordination method between cells, which is used for the coordination of space, time, frequency and power resources between cells. Background technique [0002] Soft frequency reuse technology is an important method to solve inter-cell interference. This technology divides all subcarriers of the OFDM (Orthogonal Frequency Division Multiple, Orthogonal Frequency Division Multiple Access) system into m groups. Different adjacent cells select subcarriers of different groups as the main subcarriers of the cell, and other subcarriers as the primary subcarriers of the cell. Then set different transmission power thresholds for the main subcarriers and sub-subcarriers of each cell, and the transmission power threshold of the main subcarrier is higher than that of the sub-subcarriers, and the coverage of the main subcarriers determines the cell boundary. The main subcarrie...
