Abstract:
Following the principle of reuse partitioning, two new frequency planning schemes are proposed, the coverage-oriented scheme and the efficiency-oriented scheme, for the cellular system with two-hop fixed relay nodes(FRNs).Compared with the efficiency-oriented scheme, the coverage-oriented scheme has higher reuse distances and is developed with emphasis on the coverage, while compared with the coverage-oriented scheme, the efficiency-oriented scheme has smaller reuse distances and is developed with emphasis on the spectral efficiency.Taking uplink as an example, both simplified analysis and intensive computer simulations are presented to offer comparisons among FRN enhanced systems with the proposed schemes, with a known channel-borrowing based frequency planning scheme and the conventional cellular system without relaying.Studies show that the FRN enhanced system with the coverage-oriented scheme provides the best coverage, while that with the efficiency-oriented scheme offers the highest area spectral efficiency.
根据复用分割原则, 提出2种新的两跳固定中继蜂窝网的频谱分配方案, 即:侧重于覆盖面积的频谱分配方案和侧重于频谱效率的频谱分配方案.相对于侧重频谱效率的频谱分配方案, 侧重于覆盖面积的频谱分配方案有较大的频谱复用距离, 从而能够提供更好的链路质量, 其重点在于解决覆盖问题.同时, 相对于侧重覆盖面积的频谱分配方案, 侧重于频谱效率的频谱分配方案的频谱复用距离较小, 从而有更高的频谱利用率, 其重点在于解决频谱效率问题.与基于信道借用的频谱分配方案及传统无中继频谱分配方案比较, 理论分析和仿真结果表明, 提出的侧重于覆盖面积的频谱分配方案能提供最好的覆盖, 同时侧重于频谱效率的频谱分配方案能得到最大的面积频谱效率.
