摘要/Abstract

摘要：

由于多层异构蜂窝网络节点的随机性、灵活性、复杂性等特点引起的层内干扰及层间干扰不容忽视,同时导致基于干扰的上行评估极为复杂。为此,从多层蜂窝网络自身结构和实际多信道环境特点出发,结合小区偏置及频率分割方案,采用随机几何理论推导多层异构蜂窝网络的用户在多信道环境下的上行平均遍历速率。实验结果表明采用频率分割方案能提高多层异构网络中用户的平均上行遍历速率。

Abstract:

Due to the characteristics of random,flexible,and complex arrangement of nodes in multi-tier heterogeneous cellular network,intra-tier and inter-tier interference cannot be ignored,which becomes more complicated when analyzing the uplink network performance.So this paper considers the structure characteristic and the practical multi-channel environment of the multi-tier heterogeneous network,combines cell bias and frequency division scheme,based on stochastic geometry theory,the user of multi-tier heterogeneous cellular network uplink average ergodic rate is derived in multi-channel environment.Experimental results show that using the frequency division scheme can improve the average upstream ergodic speed of users in multi-tier heterogeneous network.

Key words: heterogeneous cellular network, spectrum partition, cell biased, uplink, stochastic geometry
