摘要
中继技术能够对原有基站进行覆盖增强,同时OFDMA技术是下一代移动通信的主要多址方式,因而研究设计OFDMA技术约束下的中继方案,具有非常现实的意义。以LTE物理层帧结构为基础,针对OFDMA调制系统的中继实现方式进行了深入分析,结合OFDMA系统灵活的时频资源分配特点,提出针对OFDMA的多跳/单跳资源分配方法,最后,还提出一种针对FDD模式的OFDMA中继实现方案,对认为中继只能用于TDD系统的传统观念进行了前沿性的拓展。
Relay can enhance coverage of original base station, also OFDMA is the main multi - access technique in next generation mobile system, so it is very important to research relay of OFDMA system. Based on LTE physical layer technique, the relay realization scheme of OFDMA is analyzed deeply,a scheme of resource distribution between single and multi -hops is brought. In the end,a relay realization scheme of FDD OFDMA system is brought forward,and this is an innovative development for the traditional TDD relay scheme.
