摘要
载波聚合技术是LTE-A中的关键技术,与LTE系统中基站仅支持单一的载波切换相比,LTE-A中需要支持多载波的功能,因此需要一种可以支持多载波切换的方法。从RRC协议的角度出发,提出一种支持切换方案,通过在切换过程中释放源辅小区,并在切换完成后根据情况重新建立辅小区的方法,实现了带有载波聚合功能的切换,并且给出载波聚合下切换详细设计流程。最后在实际环境中对此流程进行验证,给出测试结果,实现了带有载波聚合功能的切换。
The carriers aggregation is a key technology for LTE？advanced （LTE？A） system. The multiple carrier function needs to be supported in LTE？A system,which is different from the base station in LTE system which only supports single carrier switching,so a switching system which can support multiple carrier switching is needed. a scheme to support switching is pro？posed in this paper,according to RRC protocol. The carrier switching with carrier aggregation was realized by releasing the source SCell in the process of switching and setting up a new SCell after the switching completion. The detailed design technolog？ical process in the case of carrier aggregation is offered. The practical validation result is given.
