3 GPP(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。

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 Physi-cal 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 pa-per 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.
