| 摘 要： | 随着移动通信技术的发展,用户对数据速率的要求越来越高,与此同时频谱资源紧缺的问题日益严重。为了满足LTE-A系统对带宽的需求而提出了频谱聚合技术。与LTE系统相比,LTE-A系统需要在上下行控制信道设计、功率控制、TDD特定场景等多方面做相应的改变以支持频谱聚合的功能。

| Abstract: | With the development of mobile communications,the requirements on data rate are increasing sharply.The shortage of spectrum is also becoming more serious.To deal with these problems,carrier aggregation,in which two or more component carriers are aggregated to support wider transmission bandwidths,is introduced into LTE-Advanced.Compared to LTE,the design of uplink/downlink control channel and power control,as well as some special scenarios in TDD need to be reconsidered for carrier aggregation in LTE-Advanc... |
