Abstract:

In order to improve the cell edge users' performance, a quality of service-aware inter-cell interference coordination method using a graph-based approach was proposed. Considering that the users may require a different quantity of physical resource blocks, the problem of assigning the radio resource to the users was modeled as the graph colouring. To solve the problem, an improve sequential colouring method for introducing resource allocation type was applied. Simulation shows that the proposed scheme could effectively increase the cell edge users' performance and the cell average throughout.

Key words: inter-cell interference coordination, graph colouring, radio resource management, resource allocation type
