摘要
首先指出中国移动申请到LTE FDD牌照后,为了解决LTE FDD和TD-LTE的上下行容量与4G用户的上下行流量不匹配的问题,有必要开启LTE FDD&TDD载波聚合功能,然后分析了LTE FDD&TDD载波聚合需要关注的两个关键问题,即成员载波的调度和上行HARQ信息的反馈过程,最后从LTE FDD&TDD主辅成员载波配置、LTE FDD&TDD业务承载、LTE FDD部署和LTE FDD设备选型等方面,给出了中国移动LTE FDD&TDD载波聚合部署建议。
Firstly, in order to deal with the mismatch between uplink/downlink capacity of LTE FDD and TD-LTE and uplink/ downlink traffic of 4G users after the license of LTE FDD obtained by China Mobile, it was pointed out that the launch of LTE FDD＆TDD carrier aggregation is necessary. Then, two key problems for LTE FDD＆TDD carrier aggregation including carrier scheduling and uplink HARQ feedback procedure were analyzed. Finally, from aspects of LTE FDD＆TDD primary and secondary carrier configuration, LTE FDD＆TDD service bearing, LTE FDD deployment and LTE FDD equipment selection, the suggestion on LTE FDD＆TDD carrier aggregation deployment for China Mobile was presented.
