UMTS系统中的家庭基站小区间干扰控制研究

Recently，there are a less expensive, short-range and low-power alternative solution that is named as Home Node Base-Station. The residential users install these devices served as access points to get better indoor voice and data coverage, higher-quality data services and more efficient spectrum usage. However, how to optimize the Home Node Base-Station coverage in order to suppress various interferences and reduce the negative impact on current wireless network infrastructure is becoming a significant problem. Based on the current specification and research achievements of 3GPP, in this article we overview the concepts and network architecture of Home Node Base-Station. And then we focus on illustrate the different kinds of interferences relative to Home Node Base-Station and their users, and describe how to control these interferences and self-configuration. Key words: Home Node Base-station, cell interference control.
