说明：  LTE协议栈开发必备的文档。包含了pdcch、pdsch上发送寻呼、系统消息、普通数据对应的控制参数及物理层相关api接口定义。 结合36.21X文档调研分析了相关参数的意义，对LTE学习有很大参考价值。
(LTE protocol stack to develop the necessary documentation. Contains a PDCCH, PDSCH transmitting a paging system messages, the ordinary data corresponding to the control parameters and the physical layer API interface definition. Combination 36.21X document research and analysis of the meaning of the relevant parameters, LTE learn valuable.)
