摘要 LTE系统的随机接入是UE在开始和eNode B通信之前的接入过程,是保证通信建立的决定性环节。为了突出随机接入过程在LTE系统的地位和作用,文章从随机接入过程的分类,在MAC层和PHY的功能和步骤等方面分别进行研究,尤其对随机接入过程在MAC层的流程进行论证,得出仅有一步流程是纯粹的PHY的结论,为进一步深入研究随机接入过程的PHY奠定了良好的基础。 LTE系统的随机接入是UE在开始和eNode B通信之前的接入过程,是保证通信建立的决定性环节。为了突出随机接入过程在LTE系统的地位和作用,文章从随机接入过程的分类,在MAC层和PHY的功能和步骤等方面分别进行研究,尤其对随机接入过程在MAC层的流程进行论证,得出仅有一步流程是纯粹的PHY的结论,为进一步深入研究随机接入过程的PHY奠定了良好的基础。
