Self-Organizing Networks for Next-Generation Wireless Communication Systems In this paper, we summarize the Self-Organizing Networks(SON) technique which is considered as a key technology for next-generation wireless communication system and propose two SON technique for uplink and downlink of cellular network. Recently, IEEE 802.16m and 3GPP-LTE systems also regarded SON technique as a key technology and many proposals were submitted for standardizaiton. We introduce an Adaptive Multi- Pattern Reuse(AMPR) technique for cellular downlink, which enables system optimization with reduced signal exchange among different cells. We also introduce a Decentralized Uplink Intercell interference Coordination(DUIC) technique for cellular uplink, which improves the edge-user throughput with distributed transmission control of users. Keywords: Next-generation wireless communication systems, Self-organizing networks, Intercell interference
