Description

一种信号传输方法及其相关设备
本申请要求于2017年10月26号提交中国专利局，申请号为201711018925.9、发明名称为“一种信号传输方法及其相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及天线领域，尤其涉及一种信号传输方法及其相关设备。
背景技术
无线电波分布在3Hz到3000GHz之间，在这个频谱内划分为12个带，其中，低频段传播损耗小，覆盖距离远，但是低频段***容量有限，能传播的数据信息有限，高频段***能量大，能传播更多的数据信息，但是传播损耗较大，导致覆盖距离有限。随着人们对移动通信的需求越累越高，需要的频率资源的容量也越来越大，有效利用高频段的资源成为必然。
如何在利用高频段资源进行数据传输时，还能有效避免其覆盖距离有限的缺陷呢？分布式天线装置***(distributed antenna system，DAS)是一种信号中继和信号放大***，由多组天线装置形成一个网络阵列，能够在不增加基站数量的情况下提高网络覆盖，DAS***中的拉远单元DRH接收基站传送的数据信息后将其转换为射频信号传送给天线装置头端，由天线装置头端进行信号发射，天线装置头端采用全向或者定向天线装置，因此所发射信号的覆盖方向是确定的。波束成形(beamforming，BF)技术是一种通过形成窄波束将天线装置能量集中到一定区域，其主要任务是补偿无线传播过程中由空间损耗、多径效应等因素引入的信号衰落与失真，同时降低同信道用户间的干扰，波束成形可以使将无线信号只按特定方向传播，好处是可以在期望方向上获得更好的无线信号质量，从而提高覆盖和性能。例如对用户设备进行数据传输时，可以将发射能量聚集，可以形成对准用户设备的窄波束，然后将该数据信息进行变换后发送利用该窄波束发送至用户设备。
在DAS***中，由于天线装置发射信号的方向是确定的，其信号覆盖的方向也是确定的，而波束成形技术是通过控制多个天线头端的无线发射信号，形成具有指向的波束，使无线发射信号都指向同一方向从而实现多个天线装置能量的聚集，因此在DAS***中，由于天线装置发射信号方向的确定性，无法使用波束成型技术改变无线信号即天线所发射的射频信号的发射方向，发射相同功率的信号，没有经过波束赋型的信号的覆盖范围明显比经过波束赋型的信号的覆盖范围少。

图2和图3从天线装置的角度对本申请实施例进行了描述，请参照图4，下面将从DRH的角度对本申请实施例进行说明。
下面将结合具体的应用场景对本实施例进行说明。
用户A与用户B在进行通信的过程中，首先用户A发送目标数据至基站，基站生成第一信号携带该用户数据，同时生成BF控制信号用于对天线头端进行控制，基站将第一信号和BF控制信号发送至DCU，随后DCU中转至DRH，DRH接收到两类信号后进行区分，首先对第一信号进行频率调制生成目标射频信号，随后将目标射频信号和控制信号发送至天线装置，天线头端也需要对两类信号进行区分，利用控制信号调整天线装置的加权系数形成至少两条指向相同方向的目标波束，随后利用该目标波束发送目标射频信号，达到聚集波束能量发送用户数据的目的。
401、DRH从第一信号和第二信号中确定第一信号；
DRH接收基站发送的第一信号和第二信号，当DAS***中包括有DCU时，基站先将第一信号和第二信号发送至DCU后，DCU再中转至DRH，随后，DRH根据第一信号和第二信号频率的不同，确定第一信号，需要说明的是，除了根据频率不同从第一信号和第二信号中确定第一信号外，还可以根据其他方式确定。例如，第一信号和第二信号分别携带有信号标识，该信号标识用以区分不同信号，DRH从第一信号和第二信号中确定第一信号的具体 方式此处不作限定。
在本实施例中，第一信号为携带有用户数据的信号。
402、DRH根据第一信号生成目标射频信号，目标射频信号与第二信号频率不同；
DRH确定第一信号后，在通过天线头端发射第一信号之前，由于天线头端只能发射射频信号，所以DRH需要先将第一信号转变为目标射频信号，具体转变的方式可以是通过频率调制。
在本实施例中，目标射频信号和第二信号的频率是不同的，天线装置可根据频率对收到的这两类信号进行区分。
403、DRH发送目标射频信号和第二信号至天线装置；
在本实施例中，DRH可以通过射频馈缆发送目标射频信号和第二信号至天线装置。
在本实施例中，目标射频信号为一个高频信号，第二信号可以为高频信号，也可以为低频信号，具体此处不作限定。
404、天线装置根据第二信号形成至少两条指向相同方向的目标波束发送目标射频信号。
天线装置根据第二信号形成至少两条指向相同方向的目标波束的方式与图2所示实施例步骤202类似，具体此处不在赘述。
