Description

一种同步信号块传输的方法、网络设备以及用户设备
本申请要求于2018年8月31日提交中国国家知识产权局、申请号为201811013540.8、申请名称为“一种同步信号块传输的方法、网络设备以及用户设备”的中国专利申请的优先权，以于及2018年3月13日提交中国专利局、申请号为201810202667.8、申请名称为“一种同步信号块传输的方法”的中国专利申请的优先权，它们的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术，尤其涉及一种同步信号块传输方法、网络设备以及用户设备。
背景技术
随着互联网技术的快速发展，用户对数据通信的质量提出了更高的要求，为了提供更大的带宽和更高的数据速率，在5G(Fifth Generation)移动通信系统中引入了非授权(unlicensed)频谱进行传输数据，例如，5G赫兹(Hz)和60GHz频段。由于这些高频频段具有更大的衰减，5G移动通信系统标准中提出波束(beam)的概念，通过将功率集中在某一特定方向上进行发射以提高信号覆盖范围，也即通过波束成形(Beamforming)技术形成具有方向性的波束来补偿高频段下的路径损耗。为了能够实现对所有方向上的用户设备(User Equipment(UE))的覆盖，5G网络设备需要进行波束扫描(beam sweeping)，如图1A所示，网络设备配置的一个扫描周期内可以包括N个数据帧，其中,N一般为大于20的整数，网络设备在该扫描周期的数据帧1中对所有波束方向进行扫描，而该扫描周期中其余的数据帧用于传输其他数据，也即在一个扫描周期内的某个固定时间内完成对所有波束方向上的同步信号块(Synchronization Signal Block(SSB))发送，其中SSB包括同步信号(SS)和物理广播信道(Physical Broadcast Channel(PBCH))。UE在接收到SSB后，可以取得与网络设备的时间同步，并且获得网络的基本配置信息。UE也可以反馈接收到的SSB的信号强度，以辅助网络设备选择合适的波束进行数据传输。
当使用非授权频谱进行数据传输时，由于所用频谱可能会被其他技术所采用，如Wi-Fi或蓝牙等，也可能被其他用户和运营商使用，因此在发送信号前需要执行信道监听，也就是采用先听后说(Listen-Before-Talk(LBT))，以避免对其他用户和系统的干扰。当监听到信道空闲时，可以立即发送信号，或者选择持续监听一段时间，当发现信道持续空闲则发送信号；当监听到信道被占用时，则继续监听信道。当网络设备(如，基站)执行波束扫描时，在每个波束方向上首先需要执行LBT，然而并不能保证每个波束方向上的信道都正好空闲，因此波束扫描无法保证在固定时间内每个波束方向上的SSB都成功发送。进而，导致有些波束方向上的SSB未能在一个扫描周期内的固定时间内成功发送给对应的UE，因此，导致这些UE接入网络的耗时较长，导致这些UE在同一个扫描周期内接入网络概率较低。

2.根据实施例1所述的方法，其特征在于，所述监听的信道包括该SSB对应的波束方向。
3.根据实施例1或2所述的方法，其特征在于，每个波束方向上的SSB只在每个配置帧中的特定时隙发送，若在其对应时隙无法发送，则等待下一个配置帧的对应时隙再尝试发送，直到配置帧用完或者所有SSB发送完为止。

经由上述技术方案可知，在使用非授权频谱的通信系统中，网络设备在第一目标周期检测第一波束方向所对应的第一信道使用情况，当该网络设备在第一目标周期内检测到该第一信道处于占用状态时，那么该网络设备在该第一目标周期不发送该第一波束方向所对应的第一SSB；然后网络设备可以在第二目标周期继续检测第一信道的使用情况，当网络设备检测到该第一信道处于空闲状态时，那么网络设备可以在第二目标周期通过该第一信道发送该第一SSB，从而实现在第一信道上的UE通过该第一SSB接入网络，该第一目标周期和第二目标周期为同一扫描周期的两个周期。以该目标周期作为检测周期并发送对应的SSB，而该目标周期小于现有技术中的扫描周期，所以缩短了UE接入网络的时间，提高了UE在同一扫描周期内接入网络的概率。

具体实施方式
本申请实施例提供了一种数据处理方法、网络设备以及用户设备，用于缩短UE接入网络的时间，提高了UE在同一扫描周期内接入网络的概率。
请参阅图1B，图1B为本申请实施例提供的一种应用场景系统框架示意图，在网络设备使用非授权频谱与UE进行传输数据时，由于所用频谱可能会被其他技术所采用，例如无线网络wifi或者蓝牙等，也可能被其他用户或者运营商所使用。因此，在该网络设备发送SSB之前需要执行信道监听，即采用先听后说(Listen-Before-Talk，LBT)，以避免对其他用户和系统带来干扰，需要说明的是，该非授权频谱可以为5GHz频段或者60GHz频段等，具体此处不做限定。其中，SSB为同步信号块，用于UE接入网络实现与网络设备进行数据传输。图1B为5G移动通信系统的一种系统场景示意图，网络设备可以为5G系统中的下一代基站(gNB，Next Generation Node B)，也可以是5G接入网的接入点或者传输点，还可以是其他5G接入网的网络设备，例如微基站等，具体此处不做限定。UE可以为手机、平板电脑或者电脑等，具体此处不做限定。目前，如图1A所示，在使用非授权频谱的通信系统中，网络设备对每个波束方向所对应的信道的检测以及每个波束方向所对应的SSB的发送只在一个扫描周期内的数据帧1内完成，即在该扫描周期内的某个固定时间段内完成。那么当该某个波束方向所对应的信道在该固定时间段内处于占用状态时，此时网络设备无法将该波束方向所对应的SSB发送给待接入该信道的UE，得等到下一个扫描周期的该固定时间段内再次扫描该信道，且当在下个扫描周期的该固定时间段内确定该波束方向所对应的信道空闲时才能向待接入该信道的UE发送该波束方向所对应的SSB。若网络设备在一个扫描周期内该固定时间段内确定该波束方向所对应的信道处于占用状态，则UE在一个扫描周期内都无法接收到该波束方向所对应的SSB，导致UE无法在一个扫描周期内接入网络。因此，上述方法会导致UE接入网络的耗时较长，导致UE在一个扫描周期内接入网络概率较低。
需要说明的是，本申请各实施例提供的该数据处理方法适用于在2G、3G、4G、5G或6G等移动通信系统中网络设备使用非授权频谱进行数据传输时，对应工作的非授权频谱下进行信道监听再发送SSB的过程，具体本申请不做限定。
有鉴于此，本申请一些实施例提供了一种SSB传输方法，用于缩短UE接入网络的时间，提高了UE在同一扫描周期内接入网络的概率。在使用非授权频谱的通信系统中，网络设备在第一目标周期检测第一波束方向所对应的第一信道使用情况，当该网络设备在第一目标周期内检测到该第一信道处于占用状态时，那么该网络设备在该第一目标周期不发送该第一波束方向所对应的第一SSB；然后网络设备可以在第二目标周期继续检测第一信道的使用情况，当网络设备检测到该第一信道处于空闲状态时，那么网络设备可以在第二目标周期通过该第一信道发送该第一SSB，从而实现在第一信道上的UE通过该第一SSB接入网络，该第一目标周期和第二目标周期为同一扫描周期内的两个周期。如图1A所示，一个扫描周期可以包括N个数据帧，且N一般大于20的整数。请参阅图2所示，目标周期可以是数据帧中的一个时隙。因此，以该目标周期作为检测周期来检测信道并发送信道对应的SSB，而该目标周期小于现有技术中的扫描周期，所以缩短了UE接入网络的时间，提高了UE在同一扫描周期内接入网络的概率。
本申请的一些实施例中，同一扫描周期可以包括多个数据帧所对应的时隙，一个数据帧所对应的时隙包括多个，同一扫描周期内包括的每个目标周期分别对应一个数据帧所对应的时隙中的一个时隙，即第一目标周期和第二目标周期可以为数据帧的一 个时隙。可能的第一种情况：第一目标周期和第二目标周期为同一数据帧的两个不同时隙；可能的第二种情况：第一目标周期和第二目标周期为不同数据帧中的两个时隙。
本申请的一些实施例中，数据帧的个数可以是网络设备提前配置然后预设于网络设备中的，也可以为网络设备根据实际情况再进行配置，具体此处不做限定，在后续的实施例中，仅以数据帧为网络设备配置并预设于网络设备中为例进行说明。需要说明的是，数据帧的个数以网络设备根据实际情况来配置的方案可以是网络设备不断地根据实际需求配置，当在同一扫描周期内网络设备配置的数据帧达到预设个数或者一个扫描周期的时间已达到且在该扫描周期内还存在未发送成功的SSB，那么此时网络设备可以停止配置数据帧，在下一个扫描周期重新监听，本申请对此不做限定。
本申请的一些实施例中，网络设备可以通过波束(beam)扫描的方式对所有波束方向进行扫描，监听每个波束方向的信道的功率。其中，信道的功率可以为在该网络设备所处的移动通信系统中，其他设备使用该信道发送信号所产生的能量大小，即功率大小；然后网络设备通过该功率来确定信道的使用状态。除此之外，网络设备可以通过其他方式进行扫描，例如信道扫描等；在后续的实施例中，仅以网络设备对所有波束方向进行扫描的方式为例进行说明。
本申请的一些实施例中，网络设备在监听某个波束方向所对应的信道时可以是只监听该波束方向所对应的信道，也可以是监听包含该波束方向的部分或者全部波束方向所对应的信道，具体此处不做限定，在后续的实施例中仅以网络设备在监听某个波束方向所对应的信道时，网络设备只监听该波束方向所对应的信道为例进行说明。
本申请的一些实施例中，网络设备对每个波束方向所对应的信道进行监听，其中，该波束方向可以为固定个数，网络设备在每一个数据帧的每个时隙扫描对应的波束方向；该波束方向也可以不断地改变，即在不同的数据帧中扫描的波束方向的个数可变；例如，可以将360度的方向划分为四个波束方向，每个波束方向为90度区域范围，也可以是将360度的方向划分为八个波束方向，每个波束方向为45度的区域范围，具体此处不做限定，在网络设备中不同数据帧中可以划分的方式不同，即扫描的波束方向的个数以及在数据帧的每个时隙中扫描的波束方向对应的区域范围也可以不同。
当波束方向的个数较多时，即窄波束方向，而窄波束方向的优点在于每个波束方向的范围较小，那么网络设备在每个时隙中监听的范围越小，网络设备监听得更细微，那么对不同波束方向所对应的信道的UE的覆盖率就越高。当波束方向的个数较少时，即宽波束方向，而宽波束方向的优点在于每个波束方向所对应的范围较大，所以网络设备在每个时隙中监听的范围较大，所以提高了网络设备对所有方向进行监听的效率。在后续的实施例中，仅以波束方向的个数为固定个数为例进行说明。
本申请实施例中，数据帧可以分为N个时隙，其中，当波束方向的个数固定时，N可以大于等于该波束方向。网络设备配置的数据帧在对不同波束方向上的信道的监听的方式不同，例如，网络设备可以在每个数据帧的特定时隙监听，也可以是网络设备在每个数据帧按照波束方向的顺序一个个波束方向进行监听，只有确定前一个波束方向所对应的SSB发送成功之后，才能在该数据帧的下一个时隙中监听下一个波束方向上的信道；还可以是在前面所述的这两种监听方式的数据帧混合使用，具体此处不做限定。因此，网络设备配置的数据帧在对不同波束方向所对应的信道进行监听时的监 听方式有多种，下面通过举例说明：
方式一：网络设备在每个数据帧中的特定时隙监听特定波束方向所对应的信道，也就是网络设备在每个数据帧的特定时隙只能监听特定波束方向的信道。
方式二：网络设备按照预设顺序在数据帧中的时隙监听每个波束方向所对应的信道并发送每个波束方向所对应的SSB；假设波束方向编号为1,2,3,...Z，仅当波束方向X所对应的SSB发送成功之后，网络设备才可以对波束方向X+1所对应的信道进行监听并发送对应的SSB，其中X为大于等于1且小于Z的整数。
下面结合具体的实施例对上述各种方式进行说明。
请参阅图3，介绍本申请实施例通过方式一数据处理的方法实施例，且在本实施例中，每个波束方向所对应的SSB在每个数据帧中与该SSB对应的特定时隙中发送。本申请实施例中SSB传输方法的一个实施例包括：
301、网络设备配置至少两个数据帧。
在网络设备使用非授权频谱进行传输数据时，由于所用频谱可能会被其他技术所采用，例如无线网络wifi或者蓝牙等，也可以被其他用户或者运营商所使用。因此，在该网络设备发送信号前需要执行信道监听，即采用先听后说(Listen-Before-Talk，LBT)，以避免对其他用户和系统带来干扰，其中，非授权频谱可以为5GHz频段或者60GHz频段。因此，网络设备配置至少两个数据帧，该数据帧用于在该数据帧的时间内传输对应波束方向的SSB，在一个扫描周期内，网络设备配置数据帧的个数不限定，数据帧可以按照编号进行排列。其中，每个数据帧包括N个时隙，N为大于等于1的整数。
302、网络设备在第一数据帧中检测至少一个波束方向所对应的的信道的功率。
网络设备配置了相应的数据帧之后，网络设备可以在一个扫描周期内的第一数据帧中监听每个波束方向所对应的信道的功率，其中，该第一数据帧为该网络设备配置的用于在该数据帧的时间内传输对应波束方向的SSB，且在该第一数据帧的特定时隙监听特定波束方向所对应的信道的功率；该至少一个波束方向的信道的功率为至少一个波束方向所对应的信道在其他用户或者设备通过该波束方向所对应的信道发送信号产生的能量值，通过功率来指示该波束方向所对应的信道的使用情况。下面通过举例进行说明，如图2所示，数据帧分为四个时隙，有四个波束方向，每个数据帧的特定时隙检测并发送特定波束方向所对应的SSB；例如网络设备在数据帧1中的第一个时隙检测第一个波束方向所对应的的信道的功率，在数据帧1的第二个时隙检测第二个波束方向所对应的信道的功率。
另外，数据帧包括N个时隙，当N小于波束方向的个数时，此时网络设备在第一数据帧中可以检测部分波束方向所对应的信道的功率；不在同一数据帧中对所有波束方向所对应的信道进行检测，可以通过至少两个数据帧对所有波束方向上的信道进行检测，且特定数据帧中的特定时隙监听特定波束方向上的信道。下面通过图4进行举例说明，在图4中，数据帧1和数据帧3只能监听第一个波束方向的信道和第二个波束方向的信道，而数据帧2和数据帧4只能监听第四个波束方向上的信道和第三个波束方向上的信道，即特定数据帧中的特定时隙只能监听特定波束方向上的信道。
需要说明的是，图4为针对不在同一数据帧中扫描所有波束方向上的信道，而通 过至少两个数据帧进行监听的方案，图4仅仅是一种举例说明，在实际应用中，针对图4不在同一数据帧中扫描所有波束方向所对应的信道适用于当划分的波束方向的个数较多的情况，例如当波束方向的总个数为八个时，可以每个特定数据帧监听其中的三个波束方向上的信道，也可以是每个特定数据帧中监听其中的四个波束方向所对应的信道等，并且每两个同种类型的数据帧进行传输的间隔时长不限定，只要保证这两个同种类型的数据帧在同一个扫描周期中即可。
下面举例说明另一种网络设备监听信道的方式，在每个数据帧中可以有多个特定时隙监听特定波束方向，即在一个数据帧中按照顺序循环监听不同波束方向的信道，下面通过图5进行说明这种监听方式，需要说明的是，图5仅仅是为了说明该监听方式，在实际应用当中通过该监听方式可以有更多，具体此处不做限定。下面请参阅图5，在图5中数据帧1中包括8个时隙，需要扫描的波束方向有四个，在数据帧1的第一时隙扫描第一个波束方向所对应的信道，数据帧1的第二时隙扫描第二个波束方向所对应的信道，依次扫描至第四波束方向所对应的信道；当网络设备在数据帧1的第二时隙确定第二个波束方向所对应的信道处于占用状态时，此时数据帧1可以在数据帧1的第六时隙继续监听第二个波束方向所对应的信道；而当网络设备在数据帧1的第一时隙确定第一个波束方向上的信道空闲，那么网络设备在第一时隙通过第一波束方向所对应的信道发送该波束方向所对应的SSB，那么在数据帧1的第五时隙则不需要进行，该数据帧1的第五时隙可以用于传输其他数据等，对于其他波束方向上的信道网络设备也是按照这样的监听方式进行监听，具体不再一一说明。
需要说明的是，每个波束方向所对应的信道的功率的大小与当前网络设备所处的通信系统所采用的非授权频谱的类型相关，还与该每个波束方向所对应的区域范围的大小相关，不同的非授权频谱和不同的波束方向所对应的区域范围所对应的功率不同，一般情况下，波束方向所对应的区域范围越大，则功率会相应的增加。例如，假设当前通信系统所采用的非授权频谱为5GHz频段，波束方向为90度，那么网络设备预设有对应每个波束方向所对应的信道的功率。
本实施例中，网络设备只在数据帧的特定时隙中检测特定波束方向所对应的信道，即在实际应用中，网络设备侧和UE侧可以预先设定规则，即使得UE能够根据当前所处的位置确定其所在的波束方向，并在网络设备在数据帧中的特定时隙检测其所在的波束方向所对应的信道时，UE只在该特定时隙中监听该波束方向所对应的信道，而在该数据帧的其他时隙则不监听该波束方向所对应的信道。所以，通过本方案可以使得UE在只在特定时隙监听信道，从而降低UE侧用于监听信道的功耗，提高UE的续航能力。
303、网络设备在该第一数据帧的第M时隙确定该第一波束方向上的第一信道处于占用状态。
网络设备在第一数据帧的特定时隙检测每个波束方向所对应的信道的功率，那么网络设备在检测的过程中可以确定每个波束方向所对应的信道的使用情况。网络设备在第一数据帧的特定时隙监听特定波束方向所对应的信道的功率，当网络设备在第一数据帧的对应时隙确定对应的波束方向所对应的信道的功率小于预设阈值，则网络设备发送该对应的波束方向的SSB，其中，该SSB中可以包含有该波束方向的编号，用 于网络设备记录已发送出去的SSB。当网络设备在第一数据帧的第M时隙确定该第一波束方向所对应的第一信道的功率大于预设阈值时，此时网络设备可以确定该第一波束方向所对应的第一信道处于占用状态，其中M为大于等于1的整数。而此时在第一波束方向所对应的第一信道的UE可以在该第一数据帧的第M时隙开始监听该第一信道，而在该第一数据帧中的其他时隙则不监听信道，所以UE只需特定时隙监听信道即可，相比于现有技术，大大降低了UE监听信道所损耗的功率。
需要说明的是，网络设备在第一数据帧当中监听的波束方向有多个，在图3所示的实施例中仅以第一波束方向为例进行说明，在其他波束方向上的具体传输方式都可以参考第一波束方向上的传输方式。
下面参阅图2，以网络设备第一数据帧的第二个时隙检测的波束方向为第二个波束方向为例进行说明，网络设备在数据帧1的第二个时隙检测该第二个波束方向所对应的信道的功率，其中，该第二波束方向所对应的信道的功率为其他用户或者设备通过该信道发送信号产生的能量值，通过功率来指示该信道的使用情况。例如，从图2可知，网络设备在数据帧1的第二个时隙中检测到该第二个波束方向所对应的信道处于占用状态，则网络设备在数据帧1的第二个时隙不发送该第二个波束方向所对应的SSB，那么网络设备在数据帧2的第二个时隙继续检测该第二个波束方向所对应的信道，从图2可知，在数据帧2的第二个时隙中，网络设备检测到该信道处于空闲状态，则该网络设备在数据帧2的第二个时隙发送该第二个波束方向所对应的SSB。
304、网络设备在该第一数据帧的第M时隙不发送该第一波束方向所对应的第一SSB。
网络设备在第一数据帧的第M时隙检测该第一波束方向所对应的第一信道，当该网络设备检测到该第一信道处于占用状态时，网络设备在该第一数据帧的第M时隙不发送该第一波束方向所对应的第一SSB。例如，图2中，网络设备在数据帧1的第二个时隙中检测到该第二个波束方向所对应的信道处于占用状态，则网络设备在数据帧1的第二个时隙不发送该第二个波束方向所对应的SSB。
305、网络设备在第二数据帧的第M时隙确定该第一波束方向所对应的第一信道处于空闲状态。
网络设备在第一数据帧的第M时隙检测到第一波束方向所对应的第一信道处于占用状态，那么网络设备可以在第二数据帧的第M时隙继续检测该第一信道的功率，当网络设备在第二数据帧的第M时隙确定该第一信道的功率小于预设阈值时，网络设备可以确定该第一信道处于空闲状态，其中M为大于等于1的整数。需要说明的是，在第一数据帧中已成功发送出去的对应波束方向所对应的SSB，在第二数据帧的对应时隙中可以不检测该对应波束方向所对应的信道，那么第二数据帧中的对应时隙可以用来传输其他数据，或者不做任何操作，具体此处不做限定。
下面举例再说明，如图2所示，网络设备在数据帧1的第二个时隙确定第二个波束方向所对应的信道被占用，那么网络设备在数据帧2中的第二个时隙继续检测该第二波束方向所对应的信道的功率，然后网络设备在数据帧2的第二个时隙中确定该功率小于预设阈值；那么此时网络设备在数据帧2的第二个时隙可以确定该第二个波束方向所对应的信道处于空闲状态。
306、网络设备在第二数据帧的第M时隙通过该第一信道向该第一信道上的UE发送第一SSB。
网络设备可以在第二数据帧的第M时隙通过该第一信道向第一信道上的UE发送第一SSB。其中，第一数据帧和第二数据帧为网络设备配置的同一扫描周期的两个数据帧，第二数据帧为在第一数据帧之后，并且与第一数据帧相邻的数据帧，其中M为大于等于1的整数。另外，该第一信道上的UE在该实施例中，仅在每个数据帧的第M时隙监听该第一信道，而在数据帧的其他时隙该UE可以不监听信道，所以UE只需要在每个数据帧的第M时隙监听信道来获取对应的SSB即可，这样可以降低UE的功耗。
例如，图2中网络设备在数据帧2的第二个时隙确定第二个波束方向所对应的信道处于空闲状态，那么网络设备在数据帧2的第二个时隙发送该第二个波束方向所对应的SSB；需要说明的是，该数据帧1、数据帧2以及数据帧3为同一波束扫描周期内的三个数据帧；其次，当网络设备在数据帧3仍未发送所有波束方向对应的SSB时，网络设备可以在数据帧4继续监听对应的波束方向所对应的信道，直到网络设备预先配置的数据帧使用完或达到一个波束扫描周期的时间。
307、UE根据该第一SSB接入网络。
UE接收到网络设备发送的第一SSB之后，UE可以根据该第一SSB接入网络。具体可以是UE根据该第一SSB获取接入网络信息，例如网络的可用资源，如频率和时间等，然后根据该接入网络信息发起随机接入。
本申请实施例中，当网络设备在第一数据帧的第M时隙检测到该第一波束方向所对应的第一信道处于占用状态时，那么网络设备在该第一数据帧的第M时隙不发送该第一波束方向所对应的第一SSB，然后网络设备在第二数据帧的第M时隙继续检测该第一信道，当该网络设备在第二数据帧的第M时隙检测到该第一信道处于空闲状态时，网络设备在该第二数据帧的第M时隙发送该第一SSB，从而实现第一信道上的UE通过该第一SSB接入网络，该第一数据帧和第二数据帧为同一扫描周期中的两个数据帧。以数据帧的时长作为检测周期并发送对应的SSB，而该数据帧的时长远小于现有技术中的扫描周期，所以缩短了UE接入网络的时间，提高了UE在同一扫描周期内接入网络的概率。
在一些实施例中，所述方法还可以包括如下步骤：
308、网络设备在第三数据帧的第M时隙确定在该第一波束方向所对应的第一信道处于占用状态。
UE接入网络之后，UE通过第一SSB可以确定网络设备的基本配置信息，所以UE只需要在数据帧的特定时隙监听该第一信道并接收该第一波束方向所对应的第一SSB，这样可以降低UE监听信道的功耗。网络设备在第三数据帧的第M时隙检测到在该第一信道的功率大于预设阈值时，那么网络设备在第三数据帧的第M时隙可以确定在该第一信道处于占用状态，那么UE会在第四数据帧的该第M时隙继续监听该第一信道，其中，第三数据帧、第四数据帧与第一数据帧、第二数据帧不为同一波束扫描周期内，且第三数据帧和第四数据帧所位于的扫描周期与第一数据帧所在的扫描周期是相邻的两个扫描周期。
309、网络设备在第三数据帧的第M时隙不发送该第一SSB。
网络设备确定了在第三数据帧的第M时隙第一波束方向所对应的第一信道处于占用状态，那么网络设备在第三数据帧的第M时隙不发送该第一SSB。
310、网络设备在第四数据帧的第M时隙确定该第一波束方向所对应的第一信道处于空闲状态。
网络设备在第四数据帧的第M时隙继续检测该第一信道的功率，当网络设备检测到该功率小于预设阈值时，网络设备可以在第四数据帧的第M时隙确定该第一信道处于空闲状态，其中第四数据帧与第三数据帧为同一扫描周期内的数据帧。
311、网络设备在第四数据帧的第M时隙通过该第一信道向该第一信道上的UE发送该第一SSB。
网络设备在第四数据帧的第M时隙确定该第一信道处于空闲状态时，此时网络设备可以在第四数据帧的第M时隙通过该第一信道向该第一信道上的UE发送第一SSB。
312、UE根据该第一SSB与网络同步。
UE接收到网络设备的发送的第一SSB之后，UE可以根据该第一SSB获取网络配置信息，根据该网络配置信息调整其时钟，实现与网络同步的过程。
请参阅图6，介绍本申请实施例通过方式二SSB传输方法实施例，且在本实施例中，每个波束方向所对应的SSB在数据帧的时隙中按照预设顺序发送。本申请实施例中SSB传输方法的另一个实施例包括：
601、网络设备配置至少两个数据帧。
步骤601与前述图3中的步骤301类似，具体此处不再赘述。
602、网络设备在第一数据帧中检测至少一个波束方向上的信道的功率。
网络设备配置了相应的数据帧之后，网络设备可以在一个扫描周期内的第一数据帧检测每个波束方向所对应的信道的功率，其中，该第一数据帧为网络设备配置的用于在该数据帧的时长内传输对应波束方向的SSB，且网络设备按照预设顺序在数据帧中的时隙检测每个波束方向所对应的信道的功率，当网络设备确定对应波束方向的信道的功率小于预设阈值时，发送该波束方向所对应的SSB；假设波束方向编号为1,2,3,...Z，仅当波束方向X所对应的SSB发送成功之后，网络设备才可以对波束方向X+1的信道进行检测并发送对应的SSB，其中X为大于等于1且小于Z的整数。
下面通过举例进行说明，如图7所示，网络设备在数据帧1的第一个时隙监听第一个波束方向所对应的信道的功率，图7可知在数据帧1的第一个时隙可以确定该第一个波束方向所对应的信道处于空闲状态，网络设备在数据帧1的第一个时隙发送第一个波束方向所对应的SSB；然后网络设备在数据帧1的第二个时隙监听第二个波束方向所对应的信道的功率，从图7可知在数据帧1的第二个时隙可以确定该第二个波束方向所对应的信道处于占用状态，然后网络设备在数据帧1的第三时隙继续检测第二个波束方向所对应的信道的功率，从图7可知在数据帧1的第三个时隙可以确定第二个波束方向所对应的信道处于空闲状态，那么网络设备在数据帧1的第三个时隙发送第二个波束方向所对应的SSB；然后网络设备在数据帧1的第四时隙检测第三个波束方向所对应的信道，从图7可知，网络设备监听第三个波束方向所对应的信道，直到数据帧2的第二个时隙才确定第三波束方向所对应的信道处于空闲状态，此时才将第三个波束方向所对应的SSB发送出去。即在本实施例中，网络设备按照预设顺序在 数据帧的时隙检测各波束方向所对应的信道，直到所有波束方向所对应的SSB都成功发送出去为止，或者直到在一个扫描周期内，网络设备配置的数据帧使用完才停止。其中，数据帧1、数据帧2和数据帧3都为同一周期内网络设备配置的数据帧。
603、网络设备在第一数据帧的最后一个时隙确定该第一波束方向所对应的第一信道处于占用状态。
网络设备在第一数据帧中检测对应波束方向的信道，当网络设备在第一数据帧的最后一个时隙确定第一波束方向所对应的第一信道的功率大于预设阈值时，此时网络设备可以在第一数据帧的最后一个时隙确定该第一波束方向所对应的第一信道处于占用状态。下面通过图7进行说明，图7中网络设备在数据帧1的第四个时隙可以确定第三个波束方向所对应的信道处于占用状态，而第四个时隙为数据帧1的最后一个时隙。
需要说明的是，网络设备在第一数据帧当中监听的波束方向有多个，在图6所示的实施例中仅以第一波束方向为例进行说明，在其他波束方向上的具体传输方式都可以参考第一波束方向的传输方式。
604、网络设备在第一数据帧的最后一个时隙不发送该第一波束方向所对应的第一SSB。
网络设备在第一数据帧的时隙中按照波束方向的编号顺序对每个波束方向所对应的信道进行检测，假设波束方向编号为1，2,3...Z，仅当第X波束方向所对应的SSB发送成功之后，网络设备才可以对第X+1波束方向的信道进行监听，其中X为大于等于1且小于Z的整数。因此，网络设备在第一数据帧中按照波束方向的编号顺序对每个波束方向的信道进行检测的过程，当网络设备确定了在第一数据帧的最后一个时隙第一波束方向所对应的第一信道处于占用状态时，网络设备在第一数据帧的最后一个时隙不发送该第一波束方向所对应的第一SSB。例如，从图7可知，网络设备在数据帧2的第二个时隙检测第二个波束方向所对应的信道，网络设备在该第二个时隙确定该第二个波束方向所对应的信道处于占用状态，然后网络设备在数据帧1的第三个时隙继续检测该第二波束方向所对应的信道，确定该第二个波束方向所对应的信道处于空闲状态时，网络设备才在数据帧1的第三个时隙发送第二个波束方向所对应的SSB；然后网络设备在数据帧1的第四个时隙中继续检测第三个波束方向所对应的信道，当网络设备可以确定第三波束方向所对应的信道处于占用状态，所以网络设备在数据帧1的第四个时隙不发送该第三个波束方向所对应的SSB。
605、网络设备在第二数据帧的第一个时隙确定该第一信道处于空闲状态。
网络设备在第一数据帧的最后一个时隙未发送出第一波束方向所对应的第一SSB，那么网络设备在第二数据帧的第一个时隙继续检测该第一波束方向所对应的第一信道的功率，当该网络设备在第二数据帧第一个时隙检测到该第一信道的功率小于预设阈值时，网络设备可以在第二数据帧的第一个时隙确定第一波束方向的第一信道处于空闲状态，其中，第一数据帧和第二数据帧为同一扫描周期内的网络设备配置的两个数据帧，并且第二数据帧为该第一数据帧之后，并且与该第一数据帧相邻的数据帧，用于传输波束方向所对应的SSB。例如，从图7可知，网络设备在数据帧2的第一个时隙继续检测该第三个波束方向所对应的信道，当网络设备检测到第三个波束方向所对 应的信道的功率大于预设阈值，那么网络设备仍然不发送该第三个波束方向所对应的SSB，在数据帧2的第二个时隙继续检测该第三个波束方向所对应的信道，当检测到该第三个波束方向所对应的信道的功率小于预设阈值时，网络设备可以确定该第三个波束方向所对应的信道处于空闲状态。
606、网络设备在第二数据帧的第一个时隙通过该第一信道发送第一SSB。
网络设备在第二数据帧的第一时隙确定该第一波束方向所对应的第一信道处于空闲状态之后，网络设备在第二数据帧的第一时隙通过该第一信道发送第一SSB，以使得在第一信道上的UE接收该第一SSB。需要说明的是，在第二数据帧中将在第一数据帧中未成功发送的波束方向所对应的SSB全部发送成功之后，如果第二数据帧中还有对应配置的时隙未使用时，那么此时这些时隙可以用来传输数据，也可以不做任何操作，具体此处不做限定。例如，如图7所示，由于在数据帧2中的最后一个时隙检测到该第四个波束方向所对应的信道处于占用状态，因此，网络设备在数据帧3的第一个时隙继续检测该第四个波束方向所对应的信道，当网络设备检测到该第四个波束方向所对应的信道处于空闲状态时，发送第四波束方向所对应的SSB至第四波束方向所对应的信道的UE。
607、UE通过第一SSB接入网络。
步骤607与前述图3中的步骤307类似，具体此处不再赘述。
在一些实施例中，所述方法还可以包括如下步骤：
608、网络设备在第三数据帧的第M时隙确定该第一波束方向所对应的第一信道处于占用状态。
UE通过第一SSB接入网络之后，可以获取到网络的配置信息，因此，可以在数据帧的对应时隙监听该第一波束方向所对应的信道并接收对应的SSB，这样可以降低UE监听信道的功耗。网络设备可以在第三数据帧的第M时隙监听该第一信道的功率，当网络设备确定该功率大于预设阈值时，网络设备在该第三数据帧的第M时隙可以确定该第一波束方向所对应的第一信道处于占用状态；其中，M为大于等于1的整数。在第三数据帧第M-1时隙时，网络设备已经将在将第一波束方向之前的其他波束方向所对应的SSB成功发送出去，该网络设备使用该第三数据帧的第M时隙监听该第一波束方向上所对应的第一信道的功率。其中，该第三数据帧与第一数据帧和第二数据帧属于不同扫描周期内的数据帧。
609、网络设备在第三数据帧的第M+1时隙确定该第一波束方向所对应的第一信道处于空闲状态。
网络设备在第三数据帧的第M+1时隙继续监听该第一波束方向所对应的第一信道的功率，当该网络设备确定该功率小于预设阈值时，此时该网络设备可以确定在第三数据帧的第M+1时隙该第一波束方向所对应的第一信道处于空闲状态。
610、网络设备在第三数据帧的第M+1时隙通过该第一信道发送第一SSB。
网络设备在第三数据帧的第M+1时隙确定该第一信道处于空闲状态，那么网络设备在第三数据帧的第M+1时隙可以通过该第一信道发送第一SSB。
611、UE根据该第一SSB与网络同步。
步骤611与前述图3中的步骤312类似，具体此处不再赘述。
本申请实施例中，当网络设备在第一数据帧的最后一个时隙检测到该第一波束方向所对应的第一信道处于占用状态时，那么网络设备在该第一数据帧的最后一个时隙不发送该第一波束方向所对应的第一SSB，然后网络设备在第二数据帧的第一个时隙继续扫描该第一信道，当该网络设备在第二数据帧的第一个时隙检测到该第一信道处于空闲状态时，网络设备在该第二数据帧的第一个时隙发送该第一SSB，从而实现第一信道上的UE通过该第一SSB接入网络，该第一数据帧和第二数据帧为不同数据帧中的两个数据帧两个时隙，并且该第二数据帧在第一数据帧之后，且与该第一数据帧相邻。以该数据帧的一个时隙的时长作为检测周期并发送对应的SSB，而该数据帧的时隙远小于现有技术中的扫描周期，所以缩短了UE接入网络的时间，提高了UE在同一扫描周期内接入网络的概率。
针对上述对方式二的数据传输方式，步骤601至步骤611为针对第一波束方向所对应的第一信道在第一数据帧的最后一个时隙监听，并且在第一数据帧的最后一个时隙内该第一信道处于占用状态，然后在第二数据帧的第一个时隙继续监听该第一信道的过程。而针对方式二的监听方式，当该第一目标周期和第二目标周期为不同数据帧的两个时隙时，第一目标周期可以对应第一数据帧的第M时隙，第一SSB为在第一数据帧所对应的时隙中未发送的SSB中的第N个，第二目标周期对应第二数据帧的第Y时隙，其中，第二数据帧为该第一数据帧之后，且与该第一数据帧相邻或者不相邻的数据帧，第Y时隙是在第二数据帧中第X时隙之后的时隙中首个在第一信道上处于空闲的一个时隙，该第X时隙为成功发送了在第一数据帧所对应的时隙中未发送的第N-1个SSB的时隙，M、N、X、Y为大于等于1的整数，并且，网络设备在第一数据帧和第二数据帧的监听方式为上述所述的方式二。
下面通过举例进行说明，请参阅图7，针对第三个波束方向所对应的信道，网络设备在数据帧1的第四个时隙监听第三个波束方向所对应的信道，网络设备在数据帧1的第四个时隙确定该第三个波束方向所对应的信道处于占用状态，那么网络设备在数据帧2的第一个时隙继续监听该第三个波束方向所对应的信道，当在数据帧3的第一个时隙确定该第三个波束方向所对应的信道处于占用状态时，那么网络设备在数据帧2的第二个时隙继续监听该第三个波束方向所对应的信道。从图7可知，在数据帧2的第二个时隙检测到该第三个波束方向所对应的信道处于空闲状态，那么此时网络设备在数据帧2的第二个时隙发送该第三个波束方向所对应的SSB。
因此，在上述示例中，该第一目标周期可以理解为数据帧1的第四个时隙，该第二目标周期为数据帧2的第二个时隙，而在数据帧1的第四个时隙时，网络设备在数据帧1中未发送的SSB包括第三个波束方向所对应的SSB和第四个波束方向所对应的SSB，数据帧2的第二个时隙可以理解为在数据帧2的第一个时隙之后首先在该第三个波束方向所对应的信道处于空闲状态的时隙，即数据帧2的第二个时隙可以理解为上述所说的第二数据帧的第Y时隙，而数据帧2的第一个时隙可以理解为上述所说的第二数据帧的第X时隙，在第X时隙时，网络设备已经成功将第一个波束方向所对应的SSB和第二个波束方向所对应的SSB发送出去。在图7中，仅以数据帧1和数据帧2为相邻的两个数据帧，在实际应用中，数据帧1和数据帧2可以是不相邻的两个数据帧，只要这两个数据帧属于同一扫描周期的两个数据帧即可。
上述详细介绍了方式一和方式二的技术方案，本申请实施例中，网络设备在对不同波束方向上的信道的监听方式还可以是将方式一和方式二进行结合，即网络设备在第一数据帧中的特定时隙监听特定波束方向上的信道，然后网络设备按照预设顺序在第二数据帧的时隙监听在第一数据帧中未发送的SSB所对应的波束方向的信道。
下面对将方式一和方式二进行结合的方案进行描述，网络设备在第一数据帧中的第M时隙确定第一波束方向所对应的第一信道处于占用状态，该第一波束方向所对应的第一SSB为在第一数据帧所对应的时隙中未发送的SSB中的第N个，网络设备在第二数据帧中的第Y时隙检测到该第一信道处于空闲状态，那么网络设备在第二数据帧的第Y时隙发送该第一SSB，其中，第二数据帧为该第一数据帧之后，且与该第一数据帧相邻或者不相邻的数据帧，第Y时隙是在第二数据帧中第X时隙之后的时隙中首个在第一信道上处于空闲的一个时隙，该第X时隙为成功发送了在第一数据帧所对应的时隙中未发送的第N-1个SSB的时隙，M、N、X、Y为大于等于1的整数，其中，网络设备在第一数据帧的特定时隙监听特定波束方向所对应的信道，而在第二数据帧中是按照上述方式二进行传输。
下面以在第一数据帧所对应的时隙中未发送的SSB为第一SSB和第二波束方向所对应的SSB为例进行说明，即在第一数据帧的第M时隙检测到该第一波束方向所对应的第一信道处于占用状态，在第一数据帧的第M+1时隙确定第二波束方向所对应的信道处于占用状态，那么网络设备可以确定在第一数据帧未发送的SSB为第一SSB和第二波束方向所对应的第二SSB，其中第二波束方向的编号在第一波束方向的编号之后；其中，第一数据帧包括N个时隙，N为大于等于1的整数。需要说明的是，在第一数据帧中还可能有其他波束方向上的信道处于占用状态，在实际应用中，当有三个以上的波束方向的信道处于占用状态时，网络设备执行的操作过程类似。这里仅以两个波束方向上的信道处于占用状态为例进行说明。
那么网络设备可以在第二数据帧中的第一个时隙来监听该第一信道，其中，第一数据帧和第二数据帧为同一波束扫描周期内的两个数据帧，因为在第二数据帧中是按照波束方向的编号顺序对在第一数据帧中未发送的SSB所对应的波束方向进行监听的，第一波束方向的编号小于第二波束方向的编号，所以网络设备在第二数据帧中的第一个时隙先监听第一波束方向所对应的第一信道的功率，当网络设备在第二数据帧的第一个时隙确定第一波束方向所对应的信道处于空闲状态，那么网络设备可以在第二数据帧的第一个时隙发送第一波束方向所对应的第一SSB；当网络设备在第二数据帧的第一个时隙确定该第一信道处于占用状态时，网络设备在第二数据帧的第一个时隙不发送该第一SSB，那么网络设备在第二数据帧的第二个时隙继续检测该第一信道，直到在第二数据帧的第X个时隙中检测到该第一信道处于空闲状态时，此时网络设备在第二数据帧的第X个时隙发送该第一SSB；其中X为大于1的整数，然后网络设备在第二数据帧的第X+1时隙才开始对第二波束方向所对应的信道进行检测，具体的过程与第一波束方向所对应的信道的检测过程类似，具体不再赘述。
本申请实施例中，以方式一和方式二进行结合的方案中，对于第一波束方向所对应的第一信道的监听周期为第一数据帧的第M时隙至第二数据帧的第Y时隙，由于第一数据帧和第二数据帧为同一扫描周期中的两个数据帧，所以网络设备对第一波束方 向所对应的第一信道的监听周期远小于一个扫描周期，因此缩短了UE接入网络的时间，提高了UE在同一扫描周期内接入网络的概率。其次，在方式一和方式二进行结合的方案中，由于在第一数据帧是以方式一的形式进行波束扫描，即网络设备在数据帧的特定时隙监听特定波束方向所对应的信道，因此，UE可以设置为只在第一数据帧特定时隙监听其所处的波束方向的信道，这样能够减少UE用于监听信道的功耗，提高UE的续航能力。
下面结合图8对方式一和方式二进行结合的方案进行举例说明。请参阅图8，在图8中可知，网络设备在数据帧1中的第二个时隙确定第二个波束方向所对应的信道处于占用状态以及在数据帧1的第四个时隙确定第四个波束方向所对应的信道处于占用状态；那么网络设备在数据帧2的第一个时隙监听第二个波束方向所对应的信道，且网络设备在数据帧2的第一个时隙确定该第二波束方向所对应的信道处于占用状态；网络设备继续在数据帧2的第二个时隙中监听第二个波束方向所对应的信道，当网络设备确定在数据帧2的第二个时隙确定第二个波束方向所对应的信道处于空闲状态，则网络设备发送该第二个波束方向所对应的SSB；因为网络设备数据帧2的第二个时隙确定了第二个波束方向所对应的信道处于空闲状态，因此，网络设备在数据帧3的第三个时隙可以在数据帧1的第三个时隙监听第四个波束方向所对应的信道，从图8可知，网络设备在数据帧3中的第三个时隙和数据帧4的第四个时隙都确定该第四个波束方向所对应的信道处于占用状态，所以网络设备在数据帧3中的第一个时隙继续监听该第四个波束方向所对应的信道，从图8可知，在数据帧3的第一个时隙确定该第四波束方向所对应的信道处于空闲状态，所以网络设备在数据帧3的第一时隙发送该第四个波束方向所对应的SSB；其中，需要说明的是，该数据帧1、数据帧2和数据帧3为同一扫描周期内的数据帧，另外，数据帧1、数据帧2和数据帧3可以为如图8所示相邻的数据帧，也可以是不相邻的数据帧，具体本申请不做限定。
下面针对本申请一些实施例中第一目标周期和第二目标周期为同一数据帧的不同时隙的这种情况通过举例进行说明：
第一种情况：第一目标周期和第二目标周期可以为同一数据帧的两个连续时隙；请参阅图7，从图7可知，在数据帧1的第二个时隙网络设备检测到该第二个波束方向所对应的信道处于占用状态，则网络设备在数据帧1的第二个时隙不发送该第二个波束方向所对应的SSB；然后网络设备在数据帧1的第三个时隙继续检测该第二个波束方向所对应的信道，从图7可知，在数据帧1的第三个时隙中确定该第二个波束方向所对应的信道处于空闲状态，那么网络设备在数据帧1的第三个时隙发送该第二个波束方向所对应的SSB。所以针对方式二的数据处理方法，对于第二个波束方向的信道的检测周期可以理解为数据帧1的一个时隙的时长。
第二种情况：第一目标周期和第二目标周期可以为同一数据帧的两个不连续时隙；请参阅图5，在图5中网络设备在数据帧1的第二个时隙监听第二个波束方向所对应的信道，且该网络设备在数据帧1的第二个时隙确定该第二个波束方向所对应的信道处于占用状态；网络设备在数据帧1的第六个时隙再次监听该第二个波束方向所对应的信道，从图5可知，该网络设备在数据帧1的第六个时隙确定该第二个波束方向所对应的信道处于空闲状态，该网络设备在向该第二个波束方向所对应的信道发送该第 二个波束方向所对应的SSB；因此，针对第二个波束方向所对应的信道的监听，可以理解为该第一目标周期为该数据帧1的第二个时隙，该第二目标周期为该数据帧1的第六个时隙，即第一目标周期和第二目标周期为同一数据帧的两个不连续的时隙，且这两个不连续的时隙间隔的时长具体由数据帧的配置方式来决定。
可以理解的是，在图1A、图2、图4、图5、图7和图8所示的附图中，数据帧的长度在视觉上看到的长度不同，但实际上表达的都是一个数据帧的长度。

本申请实施例中，在使用非授权频谱的通信系统中，处理模块901在第一目标周期检测第一波束方向所对应的第一信道使用情况，当处理模块901在第一目标周期内检测到该第一信道处于占用状态时，那么处理模块901在该第一目标周期不发送该第一波束方向所对应的第一SSB；然后处理模块901可以在第二目标周期继续检测第一信道的使用情况，当处理模块901检测到该第一信道处于空闲状态时，那么收发模块902可以在第二目标周期通过该第一信道发送该第一SSB，从而实现在第一信道上的UE通过该第一SSB接入网络，该第一目标周期和第二目标周期为同一扫描周期的两个周期。以该目标周期作为检测周期并发送对应的SSB，而该目标周期小于现有技术中的扫描周期，所以缩短了UE接入网络的时间，提高了UE在同一扫描周期内接入网络的概率。
