LTE-Advanced系统异构组网环境中下行控制信道的干扰控制策略研究
首发时间:2011-12-27
摘要:在LTE-Advanced系统中,由于Pico、Femto等小功率基站的引入而导致的异构组网环境是其重要的特征。异构组网环境下小区间干扰的结构更加复杂,以往的干扰控制方案过于简化已经难以胜任要求,尤其是在控制信道方面,为了使其高效地支持数据信道的数据传输,迫切需要引入新的干扰控制方案。本文针对LTE-Advanced系统异构组网环境的特点,提出了控制信道干扰控制的改进方案,并结合ITU信道模型,在系统级平台上进行了仿真验证,分析了引入干扰控制后系统性能变化的原因,对今后的控制信道干扰控制研究提出了建议。

The research of downlink control channel interference control strategy in LTE-Advanced system heterogeneous network
Abstract:In the LTE-Advanced system, one of the most important characteristics is the introduction of Pico, Femto and other small power stations which leads to heterogeneous network environment. In heterogeneous network environment, the inter-cell interference structure becomes more complex and the formal interference control scheme is too simplified to meet requirements, particularly in the control channel, in order to make it efficient to support data channel data transmission, it's urgent to introduce a new control scheme.In this paper,we put forward some modified control channel interference control schemes and make system-level simulation based on the ITU channel model, we also analyze the change of system performance and propose some advices on the future of the control channel interference control research.
Keywords: LTE-Advanced heterogenous network interference control control channel
