METHODS AND APPARATUS FOR INTER-CELL INTERFERENCE COORDINATION SELF-ORGANIZED NETWORK

摘要

A method of resource allocation can be used in a wireless network that includes an e Node B 1011 and an operation support system (OSS) 103. A network coloring decision to assign a plurality of resource blocks to a plurality of cells within the wireless network is triggered 305 upon occurrence of a network event. A network coloring is performed 307 by assigning each cell of the plurality of cells a resource block from the plurality of resource blocks. An effect of interference among adjacent cells with a same resource block assignment is reduced as measured by a network performance metric 303 related to a number of resource block assignment conflicts over the plurality of cells.
