摘要

3GPP（第三代合作伙伴计划）在LTE-A（高级长期演进）系统中引入了载波聚合技术

这就允许UE（用户设备）能够同时调用不同的带宽。同时

PUSCH（物理上行共享信道）分配不再限定为只能传输一块连续的频谱资源

所以载波聚合下的PUSCH分配成为一个新的研究课题。而现有方案只是以前技术的复用

不能达到资源的最大化利用。文章在现有方案的基础上提出一种在载波聚合场景下最大化PUSCH资源利用的方案

系统级仿真验证表明

改进后的方案能够实现PUSCH资源利用最大化。

Abstract

In 3GPP

the Carrier Aggregation（CA）technology is introduced in the Long Term Evolution-Advanced（LTE-A） systems

which allows the User Equipment（UE）to invoke different bandwidths simultaneously.At the same time

the Physical Uplink Share Channel（PUSCH）allocation is not limited to transmitting only one continuous spectrum resource any more. Therefore

carrier aggregation-based PUSCH allocation becomes a new research topic.However

the existing schemes are only the reuse of the previous technologies and cannot maximize the utilization of recourses.On the basis of these schemes

this paper proposes a scheme where the utilization of PUSCH resources is maximized in the carrier aggregation scenario.The system simulation results show that the improved scheme can achieve the desired purpose.
