摘要:
 多小区协作技术能够解决拥堵蜂窝网络中小区边缘用户通信质量较差的问题，但是目前维纳模型无法准确分析该技术对蜂窝网络的影响。所以为了合理分析多小区协作技术带来的性能提升，文中提出利用泊松点过程的方法对蜂窝小区进行建模。在该模型下利用随机几何工具，分析了下行链路和上行链路中使用多小区协作技术情况下的覆盖概率，得到了覆盖概率准确数学表达式和该技术所能提供的增益。通过分析发现，使用多小区协作技术能明显提升小区的覆盖能力。并且随着协作越充分，该技术带来的增益越大。
Abstract:
 In response to the problem of poor communication quality suffered by edge residential users in congested cellular network,one of feasible methods is to employ multi-community collaboration technology. But now the Wyner model cannot analyze this technology accurately. In this paper,the Poisson point process is used to model the cellular community,which is able to accurately analyze communi-cation quality of users in the scenario of edge residential users employing multi-community collaboration technology. The accurate mathe-matical expressions of coverage probability in uplink and downlink regarding any user within the community are calculated using stochas-tic geometry tools. The result shows the multi-community collaboration technology can heavily promote the coverage ability. With the ad-equacy of collaboration,it can bring more enhancement in coverage ability.
