摘要 作为ITU于2010年10月通过的4G标准之一,LTE-Advanced是3GPP长期演进(LTE)标准的增强版。文章给出了3GPP LTE-Advanced标准化时间表和关键性能,分析了上行链路多天线参考信号结构,描述了物理上行共享信道(PUSCH)中的MIMO、控制信道的上行链路MI-MO和上行链路多用户MIMO的工作原理,验证了上行链路多天线增强方案的系统性能。最后,文章还预测了LTE-Advanced R11中LTE-Ad-vanced上行链路多天线增强方案发展趋势。 As one of the 4G standards approved into ITU in October 2010,LTE-Advanced is standardized by the 3rd Generation Partnership Project(3GPP) as a major enhancement of the 3GPP Long Term Evolution(LTE) standard.This paper presents the creation timeline and key performance of LTE-Advanced in 3GPP,analyzes the principle of uplink MIMO for PUSCH,uplink MIMO for control channels and uplink multi-user MIMO and demonstrates the system performance of uplink multi-antenna enhancements.In conclusion,we predict the development trends of uplink multi-antenna enhancements in LTE-Advanced.
