摘要 中继技术以其能增加覆盖、提升容量、减小发射功率并且灵活快速部署的特点在无线通信领域得到重视。将中继技术引入传统的蜂窝结构形成"基站-中继点-用户终端"的系统结构,能有效地利用整个系统的时间、频率、空间资源,因而成为LTE-Advanced的关键候选技术之一。文章从应用场景、接口与协议架构、物理层技术以及高层协议4个方面总结并归纳了LTE-Advance系统中继技术的最新标准化进展。 Relay technology in wireless networks has attracted interest because of its outstanding ability to improve coverage and capacity and reduce transmission power. It can also be easily deployed. With relay technologies, a traditional cell network can be configured as base-relay-UE system that uses time, frequency, and spatial resources effectively. The relay is one of the key technologies in an LTE-Advanced system. This paper gives an overview of recent advances in relay technologies for LTE-Advanced system. Application scenarios, interface, protocol structure, physical technologies, and high layer protocol are discussed.
