Description

波束指示方法、网络设备及终端
本申请要求于2016年9月29日提交中国专利局、申请号为201610872316.9、申请名称为“波束指示方法、网络设备及终端”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
本发明涉及无线通信技术领域，尤其涉及波束(beam)指示方法、网络设备及终端。
背景技术
随着通信技术的发展，采用多天线形成具有高天线增益的窄模拟beam来提高高频段的无线覆盖区的大小的技术被引入。其中，如图1所示，由于基站侧天线成本限制，基站管理的每个传输点(英文：transmission point，缩写：TP)在某个时刻只能形成少数几个beam，比如形成一个或两个beam。进而，网络侧在某个时刻调度的用户设备(英文：user equipment，缩写：UE)也只能是这少数几个beam覆盖范围内的UE。对于那些不在这少数几个beam覆盖范围内的用户设备(英文：user equipment，缩写：UE)而言，UE无法监听到物理下行控制信道(英文：physical downlink control channel，缩写：PDCCH)。
按照现有长期演进(英文：long term evolution，缩写：LTE)机制中的非连续接收(英文：discontinuous reception，缩写：DRX)方式，如果一个UE在某个子帧内监听到了PDCCH指示新数据传输时，该UE还需要在紧接着的一段时间内监听PDCCH；另外，按照现有LTE机制中的非DRX方式，UE需要一直监听PDCCH。然而，这对于采用beam提高高频段的覆盖区大小的技术来说，实际上在UE监听PDCCH的时刻网络侧可能并没有调度该UE，因此在这些时刻，该UE根本无法监听到PDCCH的行为，从而会导致该UE的耗电比较严重。
发明内容
本发明实施例提供beam指示方法、网络设备及终端，以至少解决在采用beam提高高频段的覆盖区大小的技术中结合现有的LTE机制UE耗电比较严重的问题。
一方面，本发明实施例提供一种波束beam指示方法，该方法包括：网络设备获取至少一个beam的调度时间信息，其中，该至少一个beam的调度时间信息包括终端当前接入的第一beam的调度时间信息，该至少一个beam的调度时间信息用于指示该终端在该至少一个beam的调度时间信息指示的调度时间上收发信号；该网络设备向该终端发送第一指示信息，该第一指示信息用于指示该至少一个beam的调度时间信息。
基于本发明实施例提供的beam指示方法，由于本发明实施例中，网络设备可以获取至少一个beam的调度时间信息，并向终端发送指示至少一个beam的调度时间信息的第一指示信息，该至少一个beam的调度时间信息包括终端当前接入的第一beam 的调度时间信息，用于指示终端在至少一个beam的调度时间信息指示的调度时间上收发信号。这样，终端就可以至少不需要在非终端当前接入的第一beam的调度时间信息指示的调度时间上监听调度控制信息(比如PDCCH)，从而很好的匹配了网络侧对第一beam覆盖范围内的终端的调度时间安排，节省了终端耗电，或者可以使得终端进行其他一些测量动作，比如测量各个beam的信号质量等。
在一种可能的设计中，该至少一个beam的调度时间信息包括该至少一个beam中的每个beam的调度时间和该每个beam的映射关系，或者，包括该至少一个beam中的每个beam的调度时间。
在一种可能的设计中，该至少一个beam的调度时间信息还包括该网络设备对应的所有beam中除了该第一beam之外的其它一个或多个beam的调度时间信息。
这样，当终端处在多个beam的覆盖重叠区域时，终端除了可以在终端当前接入的第一beam的调度时间信息指示的调度时间上传输数据，还
可以在网络设备对应的所有beam中除了第一beam之外的其它一个或多个beam的调度时间信息指示的调度时间上传输数据，从而可以充分利用系统的带宽资源，提高系统的吞吐量。
在一种可能的设计中，该至少一个beam的调度时间信息包括第一beam集合中的所有beam的调度时间信息，其中，该第一beam集合为该网络设备将该网络设备对应的所有beam分组后获得的一个或多个beam集合中包含该第一beam的一个beam集合。
在一种可能的设计中，该至少一个beam的调度时间信息包括第一beam集合中的所有beam的调度时间信息，其中，该第一beam集合为该网络设备将该网络设备对应的所有beam分组后获得的一个或多个beam集合中包含该第一beam的一个beam集合。
也就是说，为了防止终端接入的beam经常改变，可以把多个beam进行分组，网络设备可以让终端监听多个beam的调度时刻，即网络设备只通知终端对应的监听时刻，并不指示是监听哪一个beam，这样终端接入的beam即使发生改变，只要新接入的beam还在原来的beam集合中，则网络侧无需再通知该终端新beam的调度时间信息，从而节省了系统的无线资源。当然，该情况下，当终端处在多个beam的覆盖重叠区域时，终端也可以不仅在终端当前接入的第一beam的调度时间信息指示的调度时间上传输数据，还可以在第一beam集合中的所有beam中除了第一beam之外的其它一个或多个beam的调度时间信息指示的调度时间上传输数据，从而可以充分利用系统的带宽资源，提高系统的吞吐量。
在一种可能的设计中，该网络设备向该终端发送第一指示信息，包括：该网络设备通过广播消息向该终端发送第一指示信息；或者，该网络设备通过介质访问控制MAC控制元消息向该终端发送第一指示信息；或者，该网络设备通过专用无线资源控制RRC消息向该终端发送第一指示信息。

即，本发明实施例中，网络设备在接收到终端发送的请求获取至少一个beam的调度时间信息的请求消息之后，才获取至少一个beam的调度时间信息，这样对于终端接入的beam不经常改变的情况，方案可实现性更强。
在一种可能的设计中，在该网络设备向该终端发送第一指示信息之后，还包括：该网络设备接收该终端发送的第二指示信息，该第二指示信息用于指示该网络设备通过该第一beam发送第一数据发生错误；该网络设备通过第二beam向该终端发送该第一数据，其中，该第二beam为该至少一个beam中包含的beam。
由于本发明实施例提供的beam指示方法可以在数据传输错误后对数据进行重传，因此可以提高终端的接收性能。
在一种可能的设计中，该方法还包括：该网络设备向该终端发送第三指示信息，该第三指示信息用于指示该终端的当前接入需要从该第一beam切换至第三beam。
由于本发明实施例可以在切换过程中获知目标beam(即本发明实施例中的第三beam)和源beam(即本发明实施例中的第一beam)的调度时间信息，因此终端可以在切换过程中根据该调度时间信息进行数据传输，从而缩减了业务的中断时间。
在一种可能的设计中，该至少一个beam的调度时间信息还包括该第三beam的调度时间信息。
即，第三beam的调度时间信息可以由网络设备显式指示给终端，终端无需在接收到第三指示信息后再通过另外途径获取该第三beam的调度时间信息。
在一种可能的设计中，在该网络设备向该终端发送第一指示信息之后，还包括：该网络设备获取该第三beam的调度时间信息；该网络设备向该终端发送第四指示信息，该第四指示信息用于指示该第三beam的调度时间信息。
由于本发明实施例可以在切换过程中获知目标beam(即本发明实施例中的第三beam)和源beam(即本发明实施例中的第一beam)的调度时间信息，因此终端可以在切换过程中根据该调度时间信息进行数据传输，从而缩减了业务的中断时间。另外，本发明实施例中，第三beam的调度时间信息可以由网络设备显式指示给终端，终端无需在接收到第三指示信息后再通过另外途径获取该第三beam的调度时间信息。
另一方面，一种波束beam指示方法，其特征在于，该方法包括：终端接收网络设备发送的第一指示信息，该第一指示信息用于指示至少一个beam的调度时间信息，其中，该至少一个beam的调度时间信息包括该终端当前接入的第一beam的调度时间信息，该至少一个beam的调度时间信息用于指示该终端在该至少一个beam的调度时间信息指示的调度时间上收发信号；该终端根据该第一指示信息，在该至少一个beam的调度时间信息指示的调度时间上收发信号。

这样，网络设备在接收到终端发送的请求获取至少一个beam的调度时间信息的请求消息之后，才获取至少一个beam的调度时间信息。这对于终端接入的beam不经常改变的情况，方案可实现性更强。
在一种可能的设计中，若该终端接收该网络设备通过该第一beam发送的第一数据发生错误，在该终端根据该第一指示信息，在该至少一个beam的调度时间信息指示的调度时间上收发信号之后，该方法还包括：该终端向该网络设备发送第二指示信息，该第二指示信息用于指示该网络设备通过该第一beam发送第一数据发生错误；该终端接收该网络设备通过第二beam发送的该第一数据，其中，该第二beam为该至少一个beam中包含的beam；该终端将该网络设备通过该第二beam发送的该第一数据和该网络设备通过该第一beam发送的第一数据进行合并后译码。

基于图2所示的通信系统20，本发明实施例提供一种beam指示方法，如图5所示，包括如下步骤S501-S504：
S501、网络设备获取至少一个beam的调度时间信息。
其中，该至少一个beam的调度时间信息包括终端当前接入的第一beam的调度时间信息，该至少一个beam的调度时间信息用于指示该终端在至少一个beam的调度时间信息指示的调度时间上接收或发送信号。
S502、网络设备向终端发送第一指示信息，该第一指示信息用于指示该至少一个beam的调度时间信息。
S503、终端接收网络设备发送的第一指示信息。
S504、终端根据该第一指示信息，在至少一个beam的调度时间信息指示的调度时间上接收或发送信号。
其中，本发明实施例步骤S501中：
至少一个beam的调度时间信息可以包括至少一个beam中的每个beam的调度时间和每个beam的映射关系，或者，包括至少一个beam中的每个beam的调度时间。其中，每个beam的调度时间和每个beam的映射关系具体可以是每个beam的调度时间和每个beam对应的beamID的映射关系。每个beam的调度时间具体可以包括每个beam的调度起始时刻。可选的，每个beam的调度时间具体还可以包括每个beam的调度终止时刻。
示例性的，如图6所示，假设某个TP对应beam1到beam9共9个beam，则至少一个beam的调度时间信息可以包括：在时刻1调度beam1，在时刻5调度beam5，等等。即，至少一个beam的调度时间信息可以同时指示beam的标识信息和该beam的 调度时间的信息。当然，至少一个beam的调度时间信息也可以包括：在时刻1调度，在时刻5调度，等等。即，至少一个beam的调度时间信息可以仅指示beam的调度时间的信息。
具体的，网络设备可以通过如下方式获取至少一个beam的调度时间信息：
网络设备根据各个beam的业务数量及终端数目计算出每个beam的调度时间安排；或者，当终端处于多个TP的覆盖区域时，网络设备可以在多个TP之间协商每个beam的调度时间安排；或者，网络设备收到了终端的测量报告信息，测量报告信息中携带了终端获知信号质量较好的几个beam的beam ID，网络侧在对应的beam中协商各个beam的调度时间安排。
需要说明的是，本发明实施例中beam的调度时间信息实际上是指beam形成的时间信息，也可以视为beam覆盖范围内的终端的调度时间信息；本发明实施例中的调度beam实际上是指形成beam，也可以视为调度beam覆盖范围内的终端，在此进行统一说明，以下不再赘述。
需要说明的是，本发明实施例中的调度时间信息指示的调度时间可以是连续的，也可以不是连续的，本发明实施例对此不作具体限定。
比如，网络设备可以指示当前服务beam的调度时间信息为10001000，即在时刻1和时刻5调度，其他时刻不调度，且该规律持续时间长度为10ms。或者，网络设备可以指示当前服务beam的调度时间信息为11110000，即在时刻1、时刻2、时刻3和时刻4调度，其他时刻不调度，且该规律持续时间长度为10ms。
需要说明的是，本发明中的beam可以是一个窄beam，也可以是一个宽beam，该宽beam还可以对应一个小区，在此进行统一说明，以下不再赘述。
需要说明的是，由于各个beam是否存在UE及存在UE的数目可随时间变化，所以beam的调度时间信息的时间粒度应该是短时间内的，在此进行统一说明，以下不再赘述。
其中，本发明实施例步骤S502中：
该第一指示信息可以通过广播消息通知终端，也可以通过介质访问控制(英文：medium access control，缩写：MAC)控制元(英文：control element)消息通知给终端，还可以通过(英文：radio resource control，缩写：RRC)消息通知给终端，本发明实施例对此不作具体限定。
该第一指示信息的内容可以为指示终端后续多长时间内无需监听该至少一个beam是否调度了该终端，比如，以子帧或者传输时间间隔(英文：transmission time interval，缩写：TTI)为单位指示；或者，该第一指示信息的内容可以为指示后续一段时间内该至少一个beam的调度时间安排，比如以bitmap形式指示。其中，该第一指示信息中可能同时携带至少一个beam中每个beam对应的beam ID和调度时间；也可能仅携带beam的调度时间，即，网络设备只通知某个终端该终端的调度时间，但不具体通知该终端该调度时间是哪个beam的调度时间，终端只需在对应的调度时间在终端当时接入的beam上接收或发送信号即可，即终端当时接入的beam发生改变之后，终端仍然在对应的调度时间上接收或发送信号。
示例性的，假设终端当前接入的beam为beam1，步骤S501中网络设备同时获取 了beam1的调度时间、beam1的beam ID、beam2的调度时间和beam2的beam ID，则网络设备可以通过第一指示信息向终端发送beam1的调度时间，由终端根据该beam1的调度时间，以及和网络设备预先协商好的规则，确定出beam1的beam ID、beam2的调度时间和beam2的beam ID。其中，终端根据该beam1的调度时间，以及和网络设备预先协商好的规则，确定beam1的beam ID、beam2的调度时间和beam2的beam ID的具体实现可以如下：终端在接入beam1时，通过参考信号或者接入的时间安排就可以获知beam1的beam ID。终端在接入beam1之后，通过测量相邻beam的信号质量，可以获知信号质量较好的beam2的beam ID。终端根据第一指示消息中的调度时间信息指示的beam1的调度时间，可以得出beam1的调度时间之外的时间就为beam2的调度时间。可选的，本发明实施例中，终端在获知信号质量较好的beam2的beam ID之后，可以将beam2的beam ID上报给网络设备，进而网络设备可以获知beam2的beam ID。
示例性的，假设步骤S501中网络设备同时获取了beam1的调度时间、beam1的beamID、beam2的调度时间和beam2的beamID，则网络设备可以通过第一指示信息向终端发送beam1的调度时间和beam1的beamID，由终端根据该beam1的调度时间和beam1的beamID，以及和网络设备预先协商好的规则，确定出beam2的调度时间和beam2的beamID；或者，网络设备可以通过第一指示信息向终端发送beam2的调度时间和beam2的beam ID，由终端根据该beam2的调度时间和beam2的beam ID，以及和网络设备预先协商好的规则，确定出beam1的调度时间和beam1的beam ID。具体实现可参考上述示例，此处不再赘述。
当然，假设步骤S501中网络设备同时获取了beam1的调度时间、beam1的beam ID、beam2的调度时间和beam2的beam ID，则网络设备也可以通过第一指示信息向终端发送beam1的调度时间、beam1的beam ID、beam2的调度时间和beam2的beam ID，本发明实施例对该情况不作具体限定。
可选的，该第一指示信息可能是针对某个终端的，也可能是针对该至少一个beam覆盖范围内的所有终端的。比如第一指示信息通过一个公共无线网络临时标识(英文：radio network tempory identifier，缩写：RNTI)加扰，则所有终端都可获知；如果第一指示信息通过终端专用的RNTI加扰，则可针对每个终端通知。
需要说明的是，本发明实施例中，至少一个beam中每个beam对应的RNTI可能不同，网络侧可以通过广播消息或者MAC control element消息或者RRC消息通知终端在不同beam中对应的RNTI，本发明实施例对此不作具体限定。
可选的，网络设备可以通过另外一个频点向终端发送第一指示信息或者终端在不同beam中对应的RNTI，比如通过低频中的广播消息或者MAC control element消息或者RRC消息向终端发送第一指示信息或者终端在不同beam中对应的RNTI。该第一指示信息和终端在不同beam中对应的RNTI可能通过同一个消息通知给终端，也可能通过不同的消息通知给终端，本发明实施例对此不作具体限定。
其中，本发明实施例步骤S504中：
终端根据该第一指示信息，在至少一个beam的调度时间信息指示的调度时间上接收或发送信号，具体是指，终端根据该第一指示信息，可以确定出至少一个beam 的调度时间信息，进而，终端可以该至少一个beam的调度时间信息，在对应的时间内监听该至少一个beam中的调度控制信息(比如PDCCH)，看网络设备在对应的beam中是否调度了本终端，也就是说，终端可以根据该第一指示信息，在至少一个beam的调度时间信息指示的调度时间上接收下行信号；或者，终端可以根据该第一指示信息，在至少一个beam的调度时间信息指示的调度时间上发送上行信号。
由于每个TP在某个时刻只能形成少数几个beam，比如形成一个或者两个beam。因此，实际上，在某一个时刻，终端是在至少一个beam中该时刻形成的少数几个beam的调度时间信息指示的调度时间上接收或发送信号，而不是在至少一个beam中所有beam的调度时间信息指示的调度时间上接收或发送信号。
基于本发明实施例提供的beam指示方法，由于本发明实施例中，网络设备可以向终端发送指示至少一个beam的调度时间信息的第一指示信息，该至少一个beam的调度时间信息包括终端当前接入的第一beam的调度时间信息，用于指示终端在至少一个beam的调度时间信息指示的调度时间上接收或发送信号。这样，终端就可以至少不需要在非终端当前接入的第一beam的调度时间信息指示的调度时间上监听调度控制信息(比如PDCCH)，从而很好的匹配了网络侧对第一beam覆盖范围内的终端的调度时间安排，节省了终端耗电，或者可以使得终端进行其他一些测量动作，比如测量各个beam的信号质量等。
进一步的，本发明实施例中，至少一个beam的调度时间信息还可以包括网络设备对应的所有beam中除了第一beam之外的其它一个或多个beam的调度时间信息。
例如，至少一个beam的调度时间信息包括网络设备对应的所有beam的调度时间信息。这样，终端可以获知所有beam中各个beam的调度时间信息，从而当终端接入的beam发生改变之后，终端仍然知道新接入的beam的调度时间信息，也就是说，网络设备无需再次通知终端新接入的beam的调度时间信息，从而节省了系统的无线资源。
具体的，当网络设备为基站时，网络设备对应的所有beam实际上包括网络设备管理的所有beam；
当网络设备为基站管理的某一个TP时，网络设备对应的所有beam实际上包括该TP所属的基站管理的所有beam。
其中，当至少一个beam中包含多个beam时，该多个beam中的任意两个beam可能属于相同的小区，也可能属于不同的小区，本发明实施例对此不作具体限定。
这样，当终端处在多个beam的覆盖重叠区域时，终端除了可以在终端当前接入的第一beam的调度时间信息指示的调度时间上传输数据，还
可以在网络设备对应的所有beam中除了第一beam之外的其它一个或多个beam的调度时间信息指示的调度时间上传输数据，从而可以充分利用系统的带宽资源，提高系统的吞吐量。
示例性的，如图7所示，假设本发明实施例中的终端具体为UE，则若UE1处于beam3和beam4的重叠区，则至少一个beam的调度时间信息可以包括beam3的调度时间信息和beam4的调度时间信息。这样，网络侧调度beam3覆盖范围内的UE2时，如果UE2不能完全利用带宽资源，则UE1可以在beam3的调度时间信息指示的调度 时间上传输数据，从而可以充分利用系统的无线资源，提高系统的吞吐量。
当然，若至少一个beam的调度时间信息还可以包括网络设备对应的所有beam中除了第一beam之外的其它一个或多个beam的调度时间信息，则还可以使得终端移动导致beam改变时无需重新通知该终端新beam的调度时间信息，从而节省了系统的无线资源。
可选的，另一种可能的设计中，至少一个beam的调度时间信息包括第一beam集合中的所有beam的调度时间信息，其中，该第一beam集合为述网络设备将网络设备对应的所有beam分组后获得的一个或多个beam集合中包含第一beam的一个beam集合。可选的，网络设备也可能通知终端多个beam集合分别对应的调度时间信息，本发明实施例对此不作具体限定。
也就是说，为了防止终端接入的beam经常改变，可以把多个beam进行分组，获得一个或多个beam集合。网络设备可以让终端监听某一个beam集合或某几个beam集合中的多个beam的调度时刻，即网络设备只通知终端对应的监听时刻，并不指示是监听哪一个beam，这样终端接入的beam即使发生改变，只要新接入的beam还在这某一个beam集合或某几个beam集合中，则网络设备无需再通知该终端新接入的beam的调度时间信息，从而节省了系统的无线资源。其中，不同的beam集合中包含的beam可能有重叠，即不同的beam集合中包含的beam可能有相同的beam ID，本发明实施例对此不作具体限定。
当然，该情况下，当终端处在多个beam的覆盖重叠区域时，终端也可以不仅在终端当前接入的第一beam的调度时间信息指示的调度时间上传输数据，还可以在第一beam集合中的所有beam中除了第一beam之外的其它一个或多个beam的调度时间信息指示的调度时间上传输数据，从而可以充分利用系统的带宽资源，提高系统的吞吐量。
假设第一beam为beam3，第一beam集合中包含beam3和beam4，若UE1处于beam3和beam4的重叠区，则相关示例可参考图7对应的示例，此处不再赘述。
优选的，至少一个beam的调度时间信息中除了包含终端当前接入的第一beam的调度时间信息，还包括第一beam的相邻beam的调度时间信息。其中，网络设备可以通过如下方式确定第一beam的相邻beam：
网络设备在各个beam中监听终端发送的上行信号，通过比较各个beam监听到的上行信号质量确定第一beam的相邻beam。比如，选取上行信号质量好于一定门限的beam作为第一beam的相邻beam。另外，网络设备也可以通过终端上报的监听到的各个beam的信号质量确定第一beam的相邻beam；或者，终端也根据网络侧下发的事件上报第一beam的相邻beam的beam ID，比如，当相邻beam的信号质量满足一定条件时则上报测量事件。
可选的，本发明实施例还提供一种beam指示方法，如图8所示，包括如下步骤S801-S806：
S801、终端向网络设备发送请求消息，该请求消息用于请求网络设备获取至少一个beam的调度时间信息。
其中，该至少一个beam的调度时间信息包括终端当前接入的第一beam的调度时 间信息，该至少一个beam的调度时间信息用于指示该终端在至少一个beam的调度时间信息指示的调度时间上接收或发送信号。
S802、网络设备接收终端发送的请求消息。
S803、网络设备根据请求消息，获取至少一个beam的调度时间信息。
S804、网络设备向终端发送第一指示信息，该第一指示信息用于指示该至少一个beam的调度时间信息。
S805、终端接收网络设备发送的第一指示信息。
S806、终端根据该第一指示信息，在至少一个beam的调度时间信息指示的调度时间上接收或发送信号。
其中，本发明实施例中与图4所示的实施例相关步骤的描述可参考图4所示的实施例，此处不再赘述。
即，本发明实施例中，网络设备在接收到终端发送的请求获取至少一个beam的调度时间信息的请求消息之后，才获取至少一个beam的调度时间信息，这样对于终端接入的beam不经常改变的情况，方案可实现性更强。
示例性的，当终端当前接入的第一beam不经常改变时，终端可以向网络设备发送请求获取第一beam的调度时间信息的请求消息，这样，在网络设备向终端发送指示该第一beam的调度时间信息的指示信息之后，由于该第一beam不经常改变，因此该第一beam的调度时间信息可以在较长时间内一直有效。
当然，终端也可以向网络设备发送该终端是否适合采用网络设备指示的调度时间信息的指示信息，若该指示信息指示该终端适合采用网络设备指示的调度时间信息，则网络设备获取至少一个beam的调度时间信息。
示例性的，当终端当前接入的第一beam不经常改变时，终端可以向网络设备发送该终端适合采用网络设备指示的调度时间信息的指示信息，这样，网络设备可以根据该指示信息，获取第一beam的调度时间，并向终端发送指示该第一beam的调度时间信息的指示信息，由于该第一beam不经常改变，因此该第一beam的调度时间信息可以在较长时间内一直有效。
可选的，本发明实施例还提供一种beam指示方法，如图9所示，包括如下步骤S901-S909：
S901、网络设备获取至少一个beam的调度时间信息。
其中，该至少一个beam的调度时间信息包括终端当前接入的第一beam的调度时间信息，该至少一个beam的调度时间信息用于指示该终端在至少一个beam的调度时间信息指示的调度时间上接收或发送信号。
S902、网络设备向终端发送第一指示信息，该第一指示信息用于指示该至少一个beam的调度时间信息。
S903、终端接收网络设备发送的第一指示信息。
S904、终端根据该第一指示信息，在至少一个beam的调度时间信息指示的调度时间上接收或发送信号。
S905、若终端接收网络设备通过第一beam发送的第一数据发生错误，终端向网络设备发送第二指示信息，该第二指示信息用于指示网络设备通过第一beam发送第 一数据发生错误。
S906、网络设备接收终端发送的第二指示信息。
S907、网络设备通过第二beam向终端发送第一数据。
其中，第二beam为至少一个beam中包含的beam。
S908、终端接收网络设备通过第二beam发送的第一数据。
S909、终端将网络设备通过第二beam发送的第一数据和网络设备通过第一beam发送的第一数据进行合并后译码。
其中，本发明实施例中与图4所示的实施例相关步骤的描述可参考图4所示的实施例，此处不再赘述。
由于本发明实施例提供的beam指示方法可以在数据传输错误后对数据进行重传，因此可以提高终端的接收性能。
示例性的，网络设备可以通过信令通知终端可以在多个beam中合并数据或者协议规定多个beam可以合并数据，则网络设备在调度数据时，如果在beam 1中发送的数据终端没有正确接收，网络设备可以在beam 2的调度时刻对数据进行重发。终端在接收到某个beam发送的数据为重传数据时，可以根据其中的Harq id和其他beam中最新没有正确接收的相同harq id的数据进行harq合并之后译码，从而提高了终端的接收性能。
可选的，上行信号传输的过程中也可采用类似的方法进行上行数据在多个beam中的合并，从而提高网络设备的接收性能，本发明实施例在此不再赘述。
进一步的，考虑到现有技术中，如果终端在两个不同的TP或者小区间切换，则终端需要先停止在源beam的数据传输，等待目标beam的随机接入资源，然后在目标beam发起随机接入，再在目标beam中传输数据，这样会导致在切换过程中业务会中断一段时间。因此，本发明实施例还提供一种beam指示方法，以至少解决切换过程中业务会中断一段时间的问题。
如图10所示，为本发明实施例提供的一种beam指示方法，包括：
S1001、网络设备确定终端的当前接入需要从第一beam切换至第三beam。
S1002、网络设备获取至少一个beam的调度时间信息。
其中，该至少一个beam的调度时间信息包括终端当前接入的第一beam的调度时间信息和第三beam的调度时间信息，该至少一个beam的调度时间信息用于指示该终端在至少一个beam的调度时间信息指示的调度时间上接收或发送信号。
S1003、网络设备向终端发送第三指示信息，该第三指示信息用于指示终端的当前接入需要从第一beam切换至第三beam。
S1004、终端接收网络设备发送的第三指示信息。
S1005、终端根据该第三指示信息，开始将当前接入从第一beam切换至第三beam。
S1006、网络设备向终端发送第一指示信息，该第一指示信息用于指示该至少一个beam的调度时间信息。
S1007、终端接收网络设备发送的第一指示信息。
S1008、终端根据该第一指示信息，在至少一个beam的调度时间信息指示的调度时间上接收或发送信号。
其中，本发明实施例中与图4所示的实施例相关步骤的描述可参考图4所示的实施例，此处不再赘述。
其中，本发明实施例步骤S1001中：
网络设备可以在接收到终端上报测量报告之后确定终端的当前接入需要从第一beam切换至第三beam；或者，网络设备可以根据上行的测量结果确定终端的当前接入需要从第一beam切换至第三beam，本发明实施例对此不作具体限定。
其中，本发明实施例步骤S1002中：
当本发明实施例中的网络设备具体为基站管理的某一个TP时，网络设备确定终端的当前接入需要从第一beam切换至第三beam之后，若第一beam所属的TP与第三beam所属的TP不是同一个TP，则第一beam所属的TP还可以向第三beam所属的TP发送切换请求消息，用于请求第三beam的调度时间信息，由第三beam所属的TP在接收到切换请求消息之后，为该终端分配相应的调度时刻，并将第三beam的调度时间信息通知给第一beam所属的TP，进而第一beam所属的TP可以获取到第三beam的调度时间信息。
其中，本发明实施例中的步骤S1003-S1005和S1006-S1008没有必然的执行先后顺序，可以先执行步骤S1003-S1005，再执行步骤S1006-S1008；也可以先执行步骤S1006-S1008，再执行步骤S1003-S1005；还可以同时执行步骤S1003-S1005和步骤S1006-S1008，本发明实施例对此不作具体限定。
其中，本发明实施例中的第一指示信息和第三指示信息可能通过不同的消息中承载，比如均通过广播消息或者MAC control element消息或者RRC消息承载；也可能通过不同的消息承载，比如第一指示信息通过MAC control element消息承载，第三指示信息通过RRC消息承载，本发明实施例对此不作具体限定。
其中，本发明实施例步骤S1008中：
终端可以根据该第一指示信息，在对应的时间内监听第一beam或第三beam中的调度控制信息(比如PDCCH)，看网络设备在对应的beam中是否调度了本终端，也就是说，终端可以根据该第一指示信息，在第一beam的调度时间信息或者第三beam的调度时间信息指示的调度时间上接收下行信号；或者，终端可以根据该第一指示信息，在第一beam的调度时间信息或者第三beam的调度时间信息指示的调度时间上发送上行信号；或者终端可以根据该第一指示信息，在第一beam的调度时间信息或者第三beam的调度时间信息指示的调度时间上进行随机接入过程。
由于本发明实施例可以在切换过程中获知目标beam(对应图10中的第三beam)和源beam(对应图10中的第一beam)的调度时间信息，因此终端可以在切换过程中根据该调度时间信息进行数据传输，从而缩减了业务的中断时间。
可选的，如图11所示，为本发明实施例提供的又一种beam指示方法，包括：
S1101、网络设备确定终端的当前接入需要从第一beam切换至第三beam。
S1102、网络设备获取至少一个beam的调度时间信息。

S1103、网络设备向终端发送第三指示信息，该第三指示信息用于指示终端的当前接入需要从第一beam切换至第三beam。

与图10所示的实施例的区别在于，本发明实施例提供的beam指示方法中，第三beam的调度时间是终端通过从网络设备侧获取的第三beam的随机接入信息确定的；而图10提供的beam指示方法中，第三beam的调度时间是网络设备直接通知给终端的。
由于本发明实施例可以在切换过程中获知目标beam(对应图11中的第三beam)和源beam(对应图11中的第一beam)的调度时间信息，因此终端可以在切换过程中根据该调度时间信息进行数据传输，从而缩减了业务的中断时间。
