技术领域
本公开文本涉及通信技术领域，尤其涉及一种恢复数据传输的方法、终端和网络侧节点。
背景技术
由于高频段具有丰富的空闲频率资源，可以为数据传输提供更大的吞吐量，目前第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)已经完成了高频信道建模工作。其中，与低频段相比高频信号的波长短，能够在同样大小的面板上布置更多的天线阵元，利用波束赋形技术形成指向性更强，且波瓣更窄的波束。因此，将大规模天线和高频通信相结合也是未来的趋势之一。然而，由于大规模天线的高频波束很窄，所以高频波束的通信链路会很容易出现异常情况，例如，终端被物体阻挡或者终端旋转等情况下，高频波束的通信链路都会比较容易断掉、接收质量变差或者接收功率变差等异常。然而，目前通信系统中当判断高频波束的通信链路异常后，需要发起无线资源控制(RRC，Radio Resource Control)重建，再进行波束训练，以找到最优波束，从而使用最优波束恢复数据传输。可见，目前通信链路出现异常后到恢复数据传输之间存在较长时延。

具体实施方式
下面结合附图和实施例，对本公开文本的具体实施方式做进一步描述。以下实施例仅用于说明本公开文本，但不用来限制本公开文本的范围。
为使本公开文本实施例的目的、技术方案和优点更加清楚，下面将结合本公开文本实施例的附图，对本公开文本实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开文本的一部分实施例，而不是全部的实施例。基于所描述的本公开文本的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开文本保护的范围。
参见图1，图1为本公开文本实施例可应用的网络结构图。如图1所示，包括终端11和网络侧节点12，其中，终端可以是用户终端(UE，User Equipment)，例如，可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备。需要说明的是，在本公开文本实施例中并不限定终端11的具体类型。终端11可以与网络侧节点12建立通信，其中，附图中的网络可以表示终端11与网络侧节点12无线建立通信，网络侧节点12可以是传输接收点(TRP，Transmission Reception Point)，或者可以是基站，基站可以是宏站，如LTE eNB、5G NR NB等。网络侧节点12或者可以是接入点(AP，access point)。需要说明的是，在本公开文本实施例中并不限定网络侧节点12的具体类型。
第一实施例
参见图2，图2是本公开文本实施例提供的恢复数据传输的方法的流程 图，如图2所示，包括以下步骤：
步骤201、若终端与网络侧节点之间进行业务传输的高频波束的通信链路异常，所述终端接收所述网络侧节点发送的指示至少一个波束集合的触发信令。
本公开文本实施例中，上述高频波束可以是高于某一频率阈值的波束，例如，可以是频率6GHz至100GHz之间的波束。当然，还可以是其他频率的波束，例如，1GHz或者3GHz或者5GHz等等。需要说明的是，本公开文本实施例中，对高频波束的具体频率不作限定，高频波束应该理解为本领域技术人员所理解的高频波束。另外，上述高频波束还可以是波瓣窄于某波瓣阈值的波束。同样的，对于该波瓣阈值本公开文本实施例也不作限定。
上述终端与网络侧节点之间进行业务传输的高频波束可以是，终端与网络侧节点当前传输业务的高频波束，例如，传输5G网络业务的波束。而上述高频波束的通信链路异常，可以是终端与网络侧节点在该高频波束上建立的通信链路出现影响业务传输的异常，例如，通信链路断掉、传输质量降低、信号强度降低等影响业务传输的异常。
在出现通信链路异常的情况下，终端就会接收到网络侧节点发送的上述触发信令，该触发信令指示至少一个波束集合。其中，每个波束集合中至少包括一个波束，这些波束集合内包括的波束可以是高频波束，也可以是低频波束，还可以是即包括高频波束，也包括低频波束。
另外，上述通信链路异常可以是终端发现的，也可以是由网络侧节点发现的，对此本公开文本实施例不作限定。
步骤202、终端通过所述至少一个波束集合中的目标波束恢复所述业务的数据传输。
其中，所述目标波束为所述终端或者所述网络侧节点在所述至少一个波束集合中确定的目标波束。
在终端接收到上述触发信令后，就可以确定上述至少一个波束集合，以及集合内包括的波束，从而可以在这些波束内确定上述目标波束。也可以是网络侧节点在上述至少一个波束集合内确定上述目标波束后通知终端，从而终端在上述至少一个波束集合内找到上述目标波束。其中，上述目标波束可 以是一个或者多个高频波束(也可以称作窄波束)，或者上述目标波束也可以是一个或者多个低频波束。
当终端确认上述目标波束后，就可以通过上述目标波束恢复上述业务的数据传输。其中，这里恢复可以是终端与网络侧节点之间通过目标波束恢复上述业务的数据传输。另外，恢复上述业务的数据传输可以是以出现上述通信链路异常时为起点进行上述业务的数据传输。例如，终端与网络侧节点之间是在传输第T个数据包时断链的，即第T个数据传输失败，则可以从第T个数据包开始恢复数据传输。或者上述恢复业务的数据传输可以是以出现上述通信链路异常时的前n个数据包为起点进行上述业务的数据传输，例如，终端与网络侧节点之间是在传输第T个数据包时断链的，即第T个数据传输失败，则可以从第T-n个数据包开始恢复数据传输。
通过上述步骤可以实现在终端与网络侧节点之间进行业务传输的高频波束的通信链路异常后，到恢复该业务的数据传输之间，不需要发起RRC重建，从而可以降低数据传输时延，以提升用户体验。
本公开文本实施例提供的恢复数据传输的方法中，若终端与网络侧节点之间进行业务传输的高频波束的通信链路异常，所述终端接收所述网络侧节点发送的指示至少一个波束集合的触发信令；所述终端通过所述至少一个波束集合中的目标波束恢复所述业务的数据传输。其中，所述目标波束为所述终端或者所述网络侧节点在所述至少一个波束集合中确定的目标波束。从而在通信链路异常时，不需要发起RRC重建，直接可以使用上述目标波束恢复业务的数据传输，以降低通信链路出现异常后到恢复数据传输之间时延，以及还可以提升用户体验。
第二实施例
参见图3，图3是本公开文本实施例提供的恢复数据传输的方法的流程图，如图3所示，包括以下步骤：
步骤301、若终端与网络侧节点之间进行业务传输的高频波束的通信链路异常，所述终端接收所述网络侧节点发送的指示至少一个波束集合的触发信令。
上述触发信令可以是trigger信令，另外，该触发信令可以是网络侧节点 通过物理层下行控制信息(DCI，Downlink Control Information)发送的。另外，上述触发信令可以理解为触发启动波束快速恢复机制的信令，即本公开文本实施例中可以基于该信令启动波束快速恢复机制。
可选的，所述终端接收所述网络侧节点发送的指示至少一个波束集合的触发信令的步骤，包括：所述终端在宽波束或低频波束或多个窄波束接收所述网络侧节点通过物理层下行控制信息发送的指示至少一个波束集合的触发信令；其中，所述宽波束为所述终端与所述网络侧节点预先协商或者由所述网络侧节点通知的，且波瓣比所述高频波束的波瓣要宽并覆盖所述终端的波束；所述低频波束为所述终端与所述网络侧节点预先协商或者由所述网络侧节点通知的，且频率比所述高频波束的频率要低并覆盖所述终端的波束；所述窄波束为所述终端与所述网络侧节点预先协商或者由所述网络侧节点通知的，且波瓣与所述高频波束的波瓣的差值在预设范围内并覆盖所述终端的波束。
通过上述步骤可以实现通过宽波束或低频波束或多个窄波束传输上述触发信令。其中，由于宽波束为终端与网络侧节点预先协商或者由网络侧节点通知的，这样可以保证终端通过在该带波束上进行触发信令的接收，以避免终端不知道在哪个资源位置接收触发信令，而导致的传输资源浪费，以达到节约传输资源的目的。另外，由于宽波束的波瓣比上述高频波束的波瓣要宽并覆盖所述终端的波束，这样在该宽波束上传输触发信令就不容易传输失败，从而可以提高触发信令接收的成功率。
其中，由于低频波束为所述终端与所述网络侧节点预先协商或者由所述网络侧节点通知的，这样可以保证终端通过在该带波束上进行触发信令的接收，以避免终端不知道在哪个资源位置接收触发信令，而导致的传输资源浪费，以达到节约传输资源的目的。另外，由于频率比所述高频波束的频率要低并覆盖所述终端的波束，而低频信号具有波长较长、绕射能力强的特点，低频的波束传输数据的成功率高于高频波束，从而可以提高触发信令接收的成功率。
其中，由于窄波束为所述终端与所述网络侧节点预先协商或者由所述网络侧节点通知的，这样可以保证终端通过在该带波束上进行触发信令的接收， 以避免终端不知道在哪个资源位置接收触发信令，而导致的传输资源浪费，以达到节约传输资源的目的。另外，由于使用多个窄波束传输触发信令，从而可以提高触发信令接收的成功率。其中，上述通过多个窄波束发送触发信令可以是多个窄波束同时发送触发信令，且可以是同时发送相同的触发信令，以提高终端接收触发信令的成功率。
可选的，上述触发信令包括参考信号的发送图样信息(pattern)，或者上述触发信令用于指示所述终端与所述网络侧节点预先约定的参考信号的发送图样信息；其中，所述发送图样信息用于指示所述至少一个波束集合，以及指示所述终端与所述网络侧节点之间在所述至少一个波束集合内发送参考信号的次序。
本公开文本实施例中参考信号可以称作为波束恢复参考信号(BRRS，beam recovery reference single)。例如，可以是探测参考信号(SRS，Sounding Reference Signal)或者可以是解调参考信号(DMRS，De Modulation Reference Signal)，当然，也可以是其他新的参考信号(RS，Reference Signal)。对于使用SRS或DMRS作为BRRS，则用于波束恢复的资源位置可以与现有协议中不同。例如，使用第1个符号中某几个子载波。
该实施方式中，可以实现上述发送图样信息可以是网络侧节点通过上述触发信令发送给终端的，这样可以实现提高发送图样信息的灵活，例如，网络侧节点可以根据网络资源的状况确定上述发送图样信息，以适应当前网络状况。而触发信令指示网络侧节点与终端预先约定好的发送图样信息时，可以节约信令的开销。因此，该情况下，触发信令只需要包括一个指示就行，而不需要包括发送图样信息。
另外，由于上述发送图样信息指示了终端与网络侧节点传输参考信号的次序，从而可以保证终端与网络侧节点可以有效接收到对方发送的参考信号。
可选的，所述发送参考信号的次序，包括：优先发送所述至少一个波束集合内的高频波束的次序。
通过优先发送所述至少一个波束集合内的高频波束的次序，这样可以实现可以优先选择出适合的高频波束作为目标波束，从而选择出的目标波束与通信链路异常的高频波束更加相近，从而恢复业务的数据传输更加满足终端 的需求。
可选的，所述至少一个波束集合包括所述终端预先维护的包括所述高频波束在内的原波束集合，则所述发送参考信号的次序，包括：在所述原波束集合内，以所述高频波束为中心按照空间方位由近到远的发送次序；或者以所述高频波束为中心按照空间方位由远到近的发送次序；或者在所述原波束集合内，以所述高频波束为中心按照空间方位远近交替的发送次序。
其中，上述终端预先维护的包括所述高频波束在内的原波束集合可以是终端与网络侧节点共同维护的波束集合，该波束集合可以是上行或者下行波束集合。且该集合中可以是通过波束训练得到的若干个波束ID和接收功率强度。该集合中的若干个波束包括了波束训练中寻找到的最优波束、次最优波束、依次类推的几个波束。
例如，如图4所示，网络侧节点和终端原本使用黑色的波束进行数据传输。当该波束被阻挡时，网络侧节点进行下行波束的恢复，网络侧节点触发的参考信号的发送图样信息pattern可以按照在所述原波束集合内，依次以原波束为中心，由近及远执行参考信号的发送，例如发射顺序为1-2-3-4号波束。从而可以实现快速对与原波束相近的波束进行测量，而在实际就往往与原波束相近的波束更适合作为恢复业务的波束，即上述目标波束。这样优先对与原波束相近的波束进行测量，从而可以快速选择出目标波束，以避免过多的参考信号测量操作，节约终端能耗。同理，还可以实现以高频波束为中心按照空间方位由远到近的发送次序。例如，在图4中，发射顺序为4-3-2-1号波束。
另外，还可以实现在所述原波束集合内，以所述高频波束为中心按照空间方位远近交替的发送次序。同样有利用终端快速选择出目标波束，以避免过多的参考信号测量操作，节约终端能耗。例如，如果终端旋转也会导致原波束中断，那么原波束近处的窄波束很可能也偏离了最佳传输方向，因此可以在波束集合中，远近交替的发送参考信号。例如，发射顺序为1-4-2-3号波束。
可选的，所述至少一个波束集合包括所述终端预先维护的包括所述高频波束在内的原波束集合，以及至少一个目标波束集合，则所述发送参考信号 的次序，包括：在所述原波束集合和所述至少一个目标波束集合内的波束混合发送次序；或者若只包括一个目标波束集合，则优先发送所述目标波束集合内的波束的次序；或者若包括多个目标波束集合，则优先发送所述多个目标波束集合内的波束，且所述多个目标波束集合之间按集合交替发送的次序；或者若包括多个目标波束集合，则优先发送所述多个目标波束集合内的波束，且所述多个目标波束集合之间按集合顺序发送的次序。
该实施方式中，可以实现优先发送的目标波束集合，即原波束集合之外的其他波束集合。设之前所用原波束集合编号为1，上述至少一个目标波束集合包括集合2和集合3，则可以优先发射波束集合2的波束，再发射波束集合3的波束，或者在波束集合2和波束集合3中的波束交替发射，即波束集合2的第一个波束-波束集合3的第一个波束-波束集合2的第2个波束-波束集合3的第2个波束，依次类推。由于优先发送目标波束集合，这样可以实现优先测量原波束集合之外的其他波束，从而可以实现在原波束集合内的波束均不适合做作目标波束的场景下快速选择出目标波束，以节约终端的能耗。
步骤302、所述终端通过所述至少一个波束集合内的波束传输参考信号。
该步骤302中，传输参考信号可以理解为，终端与网络侧节点之间传输参考信号。对于下行波束可以是网络侧节点发送参考信号给终端，由终端根据对参考信号的测量选择出目标波束。而针对上行波束则是终端发送参考信号给网络侧节点，由网络侧节点根据对参考信号的测量选择出目标波束。
可选的，终端通过所述至少一个波束集合内的波束传输参考信号的步骤，包括：所述终端在所述至少一个波束集合内的上行波束上向所述网络侧节点发送参考信号；所述终端接收所述网络侧节点发送的指示所述目标波束的反馈信息，其中，所述目标波束为所述网络侧节点根据对所述终端发射的参考信号进行测量的测量结果确定的上行波束。
其中，终端在所述至少一个波束集合内的上行波束上向所述网络侧节点发送参考信号的次序可以参考前面实施方式中描述的发送图样信息中指示的发送次序。当然，发送次序也可以终端与网络侧节点预先约定的，对此不作限定。
通过上述步骤可以实现由终端在上行波束上发送参考信号，网络侧节点对发送的参考信号进行测量，以根据测量结果确定出上述目标波束。从而实现确定出的目标波束适合恢复上述业务的数据传输，以提高该业务的数据传输效率。例如，如图5所示，网络侧节点在下行符号发送触发信令(trigger)，终端接收到trigger，以及参考信号的发送图样信息后，在随后的上行符号根据发送图样信息使用高频波束(也可以称作窄波束或者高频窄波束)发送参考信号，网络侧节点检测后确定最优波束，并在随后的下行符号通知终端。然后使用临时最优波束，恢复业务传输。
可选的，所述终端通过所述至少一个波束集合内的波束传输参考信号的步骤，包括：所述终端接收所述网络侧节点在所述至少一个波束集合内的下行波束上发送的参考信号；所述终端对所述网络侧节点发送的参考信号进行测量，获取测量结果；所述终端根据所述测量结果，在所述至少一个波束集合的下行波束中确定所述目标波束；所述终端向所述网络侧节点发送指示所述目标波束的反馈信息。
通过上述步骤可以实现由网络侧节点在下行波束上发送参考信号，终端对发送的参考信号进行测量，以根据测量结果确定出上述目标波束。从而实现确定出的目标波束适合恢复上述业务的数据传输，以提高该业务的数据传输效率。
可选的，所述终端根据所述测量结果在所述至少一个波束集合的下行波束中确定所述目标波束的步骤，包括：所述终端根据所述测量结果，在所述至少一个波束集合的下行波束中确定传输质量最优的下行波束作为所述目标波束；或者若所述终端根据所述测量结果查找到在所述至少一个波束集合内存在传输质量高于第一预设门限的下行波束时，将所述传输质量高于预设门限的下行波束确定为所述目标波束。
通过上述步骤可以提高确定传输质量最优的下行波束作为所述目标波束，以提高业务的数据传输效率。另外，还可以实现只要查找到传输质量高于第一预设门限的下行波束时，就可以将该下行波束确定为所述目标波束，从而可以实现快速确定出目标波束，以及还可以避免过多的参考信号发送和测量，因为在确定出上述目标波束后，网络侧节点就可以停止发送参考信号， 以达到节约网络侧节点和终端的能耗的效果。
可选的，上述传输质量包括接收功率、接收质量和信噪比中的至少一项。
该实施方式中，可以实现选择接收功率、接收质量或者信噪比高于第一预设门限的波束作为目标波束，从而在使用目标波束恢复业务的数据传输时，保证数据传输的可靠性、传输效率等。
需要说明的是，第二实施例中，步骤302仅是可选的。即第二实施例中，步骤302不执行也是可以的。也就是说，所述目标波束为所述终端或者所述网络侧节点在所述至少一个波束集合中确定的目标波束。例如，目标波束为网络侧节点与终端预先在上述至少一个波束集合中约定的波束，或者目标波束可以为网络侧节点在上述至少一个波束集合中指示的波束等等。

其中，上述确定出的目标波束可以是传输质量满足预设门限的波束，或者上述目标波束可以是上述至少一个波束集合内传输质量最好的波束，以提高恢复后数据传输的传输性能和质量。
可选的，所述终端接收所述网络侧节点发送的指示至少一个波束集合的触发信令的步骤之前，所述方法还包括：所述终端确定与所述网络侧节点之间进行业务传输的高频波束的通信链路异常；所述终端向所述网络侧节点发送恢复机制通知消息。
通过上述步骤可以实现在终端确定上述高频波束的通信链路异常时，向网络侧节点发送恢复机制通知消息。这样可以及时通知网络侧节点启动波束恢复机制，以降低数据传输的时延。其中，上述确定与所述网络侧节点之间进行业务传输的高频波束的通信链路异常可以是通过物理层测量确定的。
可选的，上述通信链路异常，包括：所述终端在预定的位置没有收到来自所述网络侧节点发送的肯定应答反馈(ACK)或者否定应答反馈(NACK)；或者所述终端测量到所述通信链路的接收质量低于第二预设门限值；或者所述终端测量到所述通信链路的接收功率低于第三预设门限值；或者所述终端 测量到所述通信链路的接收信噪比低于第四预设门限值；或者所述终端测量的所述通信链路的测量值的变化率达到第五预设门限值。
其中，上述没有收到来自所述网络侧节点发送的肯定应答反馈(ACK)或者否定应答反馈(NACK)可以理解为，在与上述高频波束对应的预定的位置即没有接收到ACK也没有收到NACK，从而确定上述高频波束的通信链路断掉。上述通信链路的接收质量低于第二预设门限值可以是物理下行控制信道(PDCCH，Physical Downlink Control Channel)、或者物理下行共享信道(PDSCH，Physical Downlink Shared Channel)的接收质量低于某个第二预设门限值。而上述变化率可以是最近两次测量值的比值、或者一段时间内的测量值变化速度等。另外，本公开文本实施例中，各预设门限均是可配置，或者可以预先约定，或者由网络侧通知。
该实施方式中，可以实现在终端检测到上述任一情况时，就可以确定与所述网络侧节点之间进行业务传输的高频波束的通信链路异常，从而发送上述恢复通知消息。
可选的，上述终端向所述网络侧节点发送恢复机制通知消息的步骤，包括：所述终端通过宽波束或低频波束或多个窄波束向所述网络侧节点发送恢复机制通知消息；其中，所述宽波束为波瓣比所述高频波束的波瓣要宽的波束，所述低频波束为频率比所述高频波束的频率要低的波束，所述窄波束为波瓣与所述高频波束的波瓣的差值在预设范围内的波束。
该实施方式中，可以通过宽波束或低频波束或多个窄波束发送上述恢复机制通知消息，且这里的宽波束或低频波束或多个窄波束可以参见上面实施方式中描述的发送触发信令的宽波束或低频波束或多个窄波束，此处不作赘述，且同样可以达到提高恢复机制通知消息的成功率的有益效果。
可选的，上述所述终端确定与所述网络侧节点之间进行业务传输的高频波束的通信链路异常的步骤之后，所述终端向所述网络侧节点发送恢复机制通知消息的步骤之前，所述方法还包括：启动预设计数时长的计数器；则所述终端向所述网络侧节点发送恢复机制通知消息的步骤，包括：在所述计数器计数到达所述预设计数时长时，终端向所述网络侧节点发送恢复机制通知消息。
该实施方式中，上述预设计数时长可以是终端预先配置的，也可以是网络侧节点通知的。另外，上述启动计数器可以是在所述终端在预定的位置没有收到来自所述网络侧节点发送的肯定应答反馈(ACK)或者否定应答反馈(NACK)时启动的；或者在所述终端测量到所述通信链路的接收质量低于第二预设门限值时启动的；或者在所述终端测量到所述通信链路的接收功率低于第三预设门限值时启动的；或者在所述终端测量到所述通信链路的接收信噪比低于第四预设门限值时启动的；或者在所述终端测量的所述通信链路的测量值的变化率达到第五预设门限值时启动的。
可选的，所述终端确定与所述网络侧节点之间进行业务传输的高频波束的通信链路异常的步骤之后，所述终端接收所述网络侧节点发送的指示至少一个波束集合的触发信令的步骤之前，所述方法还包括：在所述终端与所述网络侧节点之间进行业务传输的高频波束的通信链路异常时，所述终端切换至宽波束、低频波束或者多个窄波束，并使用所述宽波束、低频波束或者多个窄波束与所述网络侧节点继续进行所述业务的数据传输；或者在所述终端与所述网络侧节点之间进行业务传输的高频波束的通信链路异常时，所述终端将所述业务挂起；其中，所述宽波束为所述终端与所述网络侧节点预先协商或者由所述网络侧节点通知的，且波瓣比所述高频波束的波瓣要宽并覆盖所述终端的波束；所述低频波束为所述终端与所述网络侧节点预先协商或者由所述网络侧节点通知的，且频率比所述高频波束的频率要低并覆盖所述终端的波束；所述窄波束为所述终端与所述网络侧节点预先协商或者由所述网络侧节点通知的，且波瓣与所述高频波束的波瓣的差值在预设范围内并覆盖所述终端的波束。
该实施方式中，可以实现在所述终端与所述网络侧节点之间进行业务传输的高频波束的通信链路异常时，终端切换到上述宽波束、低频波束或者多个窄波束继续进行所述业务的数据传输。
需要说明的是，该实施方式中，可以是在出现通信链路异常时，就可以切换到上述波束继续进行所述业务的数据传输，且在继续进行所述业务的数据传输时，可以进行确定上述目标波束的过程，以实现在确定上述目标波束过程中终端的业务不会被中断。以及还可以实现在确定上述目标波束过程将 业务挂起，等待恢复后再进行数据传输。
其中，上述继续进行所述业务的数据传输可以是以出现上述通信链路异常时为起点继续进行上述业务的数据传输。例如，终端与网络侧节点之间是在传输第T个数据包时断链的，即第T个数据传输失败，则可以从第T个数据包开始继续进行上述业务的数据传输。或者，上述继续进行所述业务的数据传输可以是以出现上述通信链路异常时的前n个数据包为起点进行上述业务的数据传输。例如，终端与网络侧节点之间是在传输第T个数据包时断链的，即第T个数据传输失败，则可以从第T-n个数据包开始继续进行上述业务的数据传输。由于使用上述波束继续进行传输的同时，可以确定上述目标波束，从而在确定上述目标波束后，就可以确定目标波束的时间点恢复上述业务的数据传输。例如，确定上述目标波束时，使用上述宽波束、低频波束或者多个窄波束传输上述业务的数据包为第M个数据包，则可以使用切换到上述目标波束并以第M个或者第M-1个数据包为起点恢复上述业务的数据传输。需要说明的是，本公开文本实施例中，在恢复业务的数据传输时，具体以哪个数据包为起点进行业务的恢复不作限定。例如，可以恢复一些终端已经完成传输的数据包，从而保证业务有更好的连续性。

该实施方式中，可以实现在切换到上述宽波束、低频波束或者多个窄波束可以以预设低调度编码方案(MCS，Modulation and Coding Scheme)或者预设小数据包(TB size)方式，这样通过MCS和小数据包可以进一步提高数据传输的成功率。

通过上述步骤可以实现在使用目标波束恢复上述业务的数据传输过程中，终端与网络侧节点通过波束训练，寻找切换波束。其中，切换波束可以理解为终端与网络侧节点之间的最优波束。例如，通过发射波束和接收波束的扫描，搜索到能获得最强接收功率的波束对，当该最强波束对与临时最优波束不同时，网络侧节点和终端将切换至最强波束对，用于数据传输。
该实施方式中，可以实现在使用目标波束传输数据时，进行波束训练，以确定更优的切换波束，以提高数据传输的传输质量。
