Abstract

The embodiment of the invention relates to an edge user scheduling method and a device thereof, wherein, the edge user scheduling method comprises the following steps: determining the strongest interference neighbor cells of the same station of the edge user of a cell as cell-level neighbor cells of the same station; determining degree of interference of the cell-level neighbor cells of the same station on the cell; determining a position relation among the cell-level neighbor cells of the same station according to the degree of interference, and scheduling the edge user of the cell accordingto the position relation. The edge user scheduling method and device help perform corresponding time domain coordination of the edge users on the neighbor cells of the same station at different positions by determining the position relation among the neighbor cells of the same station, thus reducing the interference among the cells of the same station and improving the performance of the edge user and coverage rate of the cell.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for scheduling edge users. Background technique [0002] In a Long Term Evolution (LTE) system, a cell can use the frequency band of the entire system, therefore, inter-cell interference is unavoidable, especially at the edge of the cell, performance is greatly affected by inter-cell interference, so it must Compensate for the impact of inter-cell interference on system performance, and improve the information transmission rate of users in edge areas and the coverage of the system. [0003] At present, the main inter-cell interference compensation technologies include: inter-cell interference randomization technology, inter-cell interference cancellation technology and inter-cell interference coordination technology. Among them, inter-cell interference randomization technology is to perform random scrambling after channel coding / interleaving,...
