针对第四代(4G)移动通信系统的基本需求,探讨了同频分布式FuTURE 4G TDD试验系统中的链路技术和同频分布式组网方案,给出了全链路方案设计参数以及基于可拓集合的软分数频率复用同频分布式组网方案.最后,结合外场测试环境,给出了现场实测误块率以及频率复用系数。
Based on requirements of the 4th Generation mobile communication system, link techniques and single frequency distributed networking in FUTURE TDD trial network are explored. The whole rink parameters and single frequency distributed networking based on soft fractional frequency reuse, derived according to Extension set theory, are proposed. Finally, the BLER of the whole link and frequency reuse factor of the system are presented under the trial test scenario.
