Description

非授权频谱的接入方法、装置及传输节点 技术领域
本发明涉及通信领域,具体而言,涉及一种非授权频谱的接入方法及装置及传输节点。
背景技术
机器类型通信(Machine Type Communication,简称MTC)用户终端(User Equipment,简称UE),又称机器到机器(Machine to Machine,简称M2M)用户通信设备,是目前物联网的主要应用形式。在第三代合作伙伴计划(3rd Generation Partnership Project,简称3GPP)技术报告TR45.820V200中公开了几种适用于蜂窝级物联网(Comb-Internet Of Things,简称C-IOT)的技术,其中,窄带物联网(Narrow Band-Internet Of Things,简称NB-IoT)技术最为引人注目。
众所周知长期演进(Long Term Evolution,简称LTE)是部署在授权载波中运营的。但是随着数据业务的快速增长,在不久的将来,授权频谱将不能再承受下如此巨大的数据量。因此,在非授权频谱中部署LTE,通过非授权频谱来分担授权载波中的数据流量,是后续LTE发展的一个重要的演进方向。
对于非授权频谱的使用,不同国家有着不同的管制,例如在欧洲市场,必须通过先听后说(listen-before-talk,简称LBT)的方式使用非授权频谱,对于具体的LBT机制,以帧为基础的设备(Frame Based Equipment,简称FBE)和以负载为基础的设备(Load Based Equipment,简称LBE)对应的过程是不同的。
对于FBE,LBT的过程如下:在传输之前,设备需要进行干净信道评估(Clear Channel Assessment,简称CCA),评估结果若为信道空闲,那么立即发送数据,否则直到下一个固定帧周期前,不能传输数据。固定帧 由信道占用时间(Channel Occupancy Time,简称COT)和空闲周期(Idle period)组成,其中信道占用时间在1ms到10ms之间取值,最小的空闲周期为信道占用时间的5%,在空闲周期的最后,设备进行新的CCA检测。
对于LBE,LBE过程包括初始CCA(initial CCA)过程和扩展CCA(Extended CCA)过程。有2种LBE过程,方式A:初始CCA过程:在传输之前,设备需要进行CCA,根据信道评估结果判断信道是否空闲,如果信道评估结果表示为信道为空闲,立即发送数据,否则,设备不能发送数据,并且执行扩展干净信道评估,扩展干净信道评估为q个观察时隙。观察时隙可以为非占用空闲时隙也可以为繁忙时隙。繁忙时隙为两次非占用空闲时隙之间的所有时间。q的初始值为16,当前一次扩展干净信道评估中没有检测到N个非占用空闲时隙时,q的取值加倍。一旦q值达到1024,那么下一次扩展干净信道估计的q值重设为16。N是在[1,q]中随机选择的。方式B:初始CCA过程:在传输之前,设备需要进行CCA,根据信道评估结果判断信道是否空闲,如果信道评估结果表示为信道为空,立即发送数据,否则,设备不能发送数据,并且执行扩展干净信道评估:生成随机数N,N值为一个计数器,取值范围为[1,q],然后进行CCA评估,判断信道是否被占用,如果被占用,则N值不变,继续进行CCA检测,如果信道没有被占用,N值减1,判断N值是否减到0,如果减到0,那么发送数据,否则,继续进行CCA检测。即设备进行N次的CCA检测,如果检测信道为空,N值递减,否则N值不变,当N递减为0时发送数据。对于信道占用时间管制规定最大的信道占用时间为13ms。现有管制还规定,CCA检测对应的检测长度即干净信道评估长度不小于20us。
目前通信领域中支持LTE系统即宽带系统部署在非授权频谱,但是还没有支持窄带系统部署在非授权频谱的具体方案。
针对相关技术中,无法支持窄带系统接入非授权频谱的问题,尚未提出有效的解决方案。
