LTE随机接入流程研究

Research on LTE RACH process

从LTE随机接入过程的特点、触发的环境入手,说明随机接入是保证通信建立的决定性环节;详细分析了基于竞争模式的随机接入过程的各个流程,包括流程中的各种定时器的触发条件、参数的配置以及5种触发条件在过程中的不同。

First, this paper proposes that the random access is the key point to ensure the establishment of communication from the characteristics and environment of the LTE random access process. Secondly, the paper discusses the random access process based on the competition mode, including the trigger condition and parameter configuration of different timer and the differences of five trigger conditions.
