摘要
分析了载波聚合中MAC层聚合和物理层聚合两个实现方法,结合电力应用需求,提出了HARQ的混合调度控制的载波聚合应用策略以及230 MHz频段的子载波分配方法,利用载波聚合与频谱感知技术,实现基于230 MHz频段的无线通信系统,完成了实验室功能测试,并验证了本系统在工作时不会对原230 MHz电台造成任何影响。
This paper analyzes the two implementation methods of carrier aggregation： MAC layer aggregation and physical layer aggregate. Combined with the demand for power applications, the carrier aggregation application strate- gy with HARQ hybrid scheduling control is proposed, as well as the subearrier allocation method of the 230MHz band. The 230MHz frequency band wireless communication system is realized by using carrier aggregation and spec- trum-sensing technology. The laboratory functional testing is implemented, which validates that the system at work does not affect the original 230MI-Iz radio.
