背景技术
目前通信系统中，接收端可以有一个或者多个收发单元，例如：UE可以有一个或者多个收发单元。但不管接收端有一个还是多个收发单元，发送端通过多个发送波束发送信号时，且接收端均支持同时接收这多个发送波束中部分或者全部发送波束发送的信号。例如：基站通过3个发送波束向UE发送信号，UE可能会同时接收到这3个发送波束中的1个、2个或者3个发送波束发送的信号。但目前通信系统中，发送端由于不确定哪些发送波束同时发送信号时，可以被接收端同时接收，从而可能会存在一些发送波束发送的信号无法被接收端接收的情况，这样就会浪费传输资源。可见，如何确定发送端能够同时向接收端发送信号的发送波束是当前急需解决的技术问题。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1为本公开实施例可应用的网络结构示意图，如图1所示，包括发送端11和接收端12，其中，发送端11可以是基站或者终端，而接收端12也可以是终端或者基站，例如：发送端11为基站，接收端12为终端，则可以实现终端与基站之间的通信，又或者发送端11为终端，则接收端12为基站，也可以实现终端与基站之间的通信，又或者发送端11为基站，接收端12也为基站，则可以实现基站与基站之间的通信，又或者发送端11为终端，接收端12也为终端，则可以实现终端与终端之间的通信。当然，本公开实施例中，并不限定发送端11只能是终端或者基站，例如：发送端11还可以是其他的网络侧设备，同理，接收端12也并不限定只是终端或者设备，例如：第接收端12还可以是其他的网络侧设备，对此本公开实施例不作限定。其中，附图1，以发送端11为基站，接收端12为终端进行举例示意。终端可以是用户终端(User Equipment，UE)，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，在本公开实施例中并不限定终端的具体类型。基站可以是宏站，如LTE eNB、5G NR NB等；也可以是小站，如低功率节点(LPN：low power node)pico、femto等小站，或者可以是接入点(AP，access point)；基站也可以是中央单元(CU，central unit)与其管理和控制的多个传输接收点(TRP，Transmission Reception Point)共同组成的网络节点。另外，一个基站下有一个或多个小区(例如：不同的频点或扇区分裂)。需要说明的是，在本公开实施例中并不限定基站的 具体类型。
请参考图2，本公开实施例提供一种发送波束确定方法，如图2所示，包括以下步骤：
201、发送端向接收端发送N个发送波束的波束训练信号，所述N为正整数；
202、发送端接收所述接收端发送的所述N个发送波束中的Q个发送波束的标识信息，以及所述Q个发送波束中每个发送波束的分组信息，其中，所述Q个发送波束包括G个发送波束组，所述G个发送波束组是所述接收端根据测量结果进行划分的，所述测量结果为所述接收端对所述发送端发送的波束训练信号进行接收测量得到的测量结果，所述Q和所述G均为正整数；
203、发送端确定能够通过所述Q个发送波束中属于不同发送波束组的发送波束，同时向所述接收端发送信号。
本公开实施例中，上述N个发送波束可以是发送端中的所有或者部分发送波束，例如：上述发送端可以是共有
Figure PCTCN2018077114-appb-000001
个候选的发送波束，每个发送波束可以对应一组波束赋形权值，第n个波束的发送波束赋形权值可以为
Figure PCTCN2018077114-appb-000002
其中K是波束赋形的天线单元数，可以小于发送端的天线单元数，例如一个发送波束仅从一个收发单元连接的K个天线单元发出。其中，上述
Figure PCTCN2018077114-appb-000003
可以是等于或者大于上述N，且在上述发送端为基站时，上述发送波束可以是下行发送波束，而上述发送端为终端时，上述发送波束可以是上行发送波束。
上述N个发送波束的波束训练信号可以是发送端为每个发送波束发射一个波束训练信号。例如对于
Figure PCTCN2018077114-appb-000004
个下行发送波束，基站可以发送
Figure PCTCN2018077114-appb-000005
个训练信号。另外，上述N个发送波束的波束训练信号可以是时分复用(Time Division Multiplexing，TDM)、频分复用(Frequency Division Multiplexing，FDM)或者码分复用(Code Division Multiplexing，CDM)，或者各种复用方式的组合进行发送的，对此本公开实施例不作限定。例如：以正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)为基础的系统中，
Figure PCTCN2018077114-appb-000006
个训练信号可以占用
Figure PCTCN2018077114-appb-000007
个OFDM符号，每个训练信号占用1个OFDM符号，训练信号之间为TDM复用。也可以在一个OFDM符号中发射多个波束的训 练信号，他们之间是FDM复用，或者CDM复用。
且上述N个发送波束的波束训练信号可以是使用该波束对应的波束赋形权值赋形之后发出。另外，步骤201中的发送波束训练信号可以是周期性发送，或者非周期性发送。
在发送端发送波束训练信号之后，接收端就对发送端发送的波束训练信号进行接收测量，例如：接收端对发送端发送的N个发送波束的波束训练信号进行接收测量，并根据测量结果从所述N个发送波束中选择Q个发送波束，以及将所述Q个发送波束划分为G个发送波束组，所述Q和所述G均为正整数。
其中，接收端可以是使用接收端的全部或者部分接收单元对N个发送波束的波束训练信号进行接收测量，例如：可以是接收端使用全部或者部分接收单元分别对N个发送波束中的每个发送波束的波束训练信号进行接收测量，以得到测量结果，其中，每个测量结果均包括对应的收发单元对每个发送波束的波束训练信号的测量结果。或者可以是，接收端使用全部或者部分接收单元分别对N个发送波束的波束训练信号进行接收测量，得到测量结果，其中，每个测量结果可以包括对应的收发单元对一个或者多个发送波束的波束训练信号的测量结果。
而上述Q个发送波束可以是进行上述接收测量得到的测量结果中接收质量排在前Q位的测量结果对应的发送波束，或者可以是在上述测量结果选择一定数量的测量结果，并将选择出的测结果测量对应的Q个发送波束。需要说明的是，由于针对同一个发送波束可能采用相同的收发单元进行接收测量，且这些测量结果的接收质量都比较好时，那么，针对不同的收发单元的测量结果可能会选择出相同的发送波束，即上述Q个发送波束中可能会存在相同的波束。例如：针对发送波束a，分别使用了收发单元a和收发单元b进行了接收测量，且收发单元a和收发单元b对发送波束a的测量结果的接收质量均是收发单元a和收发单元b的测量结果中最优的测量结果，从而针对收发单元a和收发单元b均会选择发送波束a。
另外，由于上述Q个发送波束是根据上述测量结果进行划分，这样一个发送波束必然与特定的收发单元或者特定收发单元组对应，从而就可以将对 应相同收发单元或者收发单元组的发送波束划分而同一个发送波束组，即一个发送波束组对应收发单元或者收发单元组。或者也可以是接收端将认为能够同时接收的发送波束划分为一个发送波束组。
这样在接收端选择Q个发送波束和划分G个发送波束组后，就可以向所述发送端发送所述Q个发送波束的标识信息，以及所述Q个发送波束中每个发送波束的分组信息。而发送端接收这些信息后，就可以知道各发送波束所属的发送波束组，进而确定能够通过所述Q个发送波束中属于不同发送波束组的发送波束，同时向所述接收端发送信号。其中，能够同时向所述接收端发送信号的发送波束可以是，这些发送波束可以同时向接收端发送信号，且可以被接收端同时接收，即能够同时向所述接收端发送信号的发送波束可以理解为发送信号能够被接收端同时接收的发送波束。另外，本公开实施例中，同时可以理解为同时一个时间点(例如一个OFDM符号)。
另外，本公开实施例中，在发送端确定能够同时向所述接收端发送信号的发送波束后，可以灵活的选择同时传输的发送波束，且发送端还可以据此选择相应的传输方式，例如通过能够同时向所述接收端发送信号的多个发送波束发送多个并行数据流实现空分复用，或者将一个数据流通过能够同时向所述接收端发送信号的多个发送波束，实现空间分集传输，以提高数据传输效率。
另外，本公开实施例中，若发送端为基站时，则发送波束为下行发送波束，若发送端为终端时，则发送波束为上行发送波束。
作为一种可选的实施方式，所述G个发送波束组分别与所述接收端的G个收发单元组对应。例如：接收端可以使用G个收发单元组对发送端发送的N个发送波束的波束训练信号进行接收测量。
其中，上述G个收发单元组可以是接收端预先划分好的，划分的方式可以是接收端自动划分的，或者接收端根据用户输入的操作而划分，或者接收端基于各收发单元的性能进行划分的，对此本公开实施例不作限定，且每个收发单元组可以包括不同或者相同数量的收发单元，每个收发单元组内至少有一个收发单元，每个收发单元组内的收发单元连接到若干个天线单元。不同收发单元组内的收发单元可以独立的对接收到的信号进行波束赋形，并送 到基带处理单元进行后续计算。
上述接收端使用G个收发单元组对发送端发送的N个发送波束的波束训练信号进行接收测量可以是，接收端使用G个收发单元组分别对N个发送波束中的每个发送波束的波束训练信号进行接收测量，以得到G个测量结果，其中，每个测量结果均包括对应的收发单元组对每个发送波束的波束训练信号的测量结果，例如：上述G为2，上述N为4，则得到2个测量结果，每个测量结果包括对于4个发送波束的测量结果。或者可以是，接收端使用G个收发单元组分别对N个发送波束的波束训练信号进行接收测量，得到G个测量结果，其中，每个测量结果可以包括对应的收发单元组对一个或者多个发送波束的波束训练信号的测量结果。
而上述Q个发送波束可以是进行上述接收测量得到的测量结果中接收质量排在前Q位的测量结果对应的发送波束，或者可以是在上述G个收发单元组每个收发单元组对应的测量结果选择一定数量的测量结果，并将选择出的测结果测量对应的Q个发送波束。需要说明的是，由于针对同一个发送波束可能采用相同的收发单元组进行接收测量，且这些测量结果的接收质量都比较好时，那么，针对不同的收发单元组的测量结果可能会选择出相同的发送波束，即上述Q个发送波束中可能会存在相同的波束。例如：针对发送波束a，分别使用了收发单元组a和收发单元组b进行了接收测量，且收发单元组a和收发单元组b对发送波束a的测量结果的接收质量均是收发单元组a和收发单元组b的测量结果中最优的测量结果，从而针对收发单元组a和收发单元组b均会选择发送波束a。
另外，由于上述Q个发送波束是根据上述G个收发单元组的测量结果进行划分，这样一个发送波束必然与一个收发单元组对应，从而就可以将对应相同收发单元组的发送波束划分而同一个发送波束组，即一个发送波束组对应一个收发单元组。
该实施方式中，由于G个发送波束组分别与所述接收端的G个收发单元组对应，从而属于不同的发送波束组的发送波束发送信号时更加容易被接收端同时接收，以提高数据传输效率。
需要说明的是，本公开实施例中，并不限定接收端通过G个收发单元组 进行接收测量，例如：接收端也可以是通过以收发单元为单位进行接收测量，并根据该测量结果选择与收发单元对应的发送波束组，即一个发送波束组对应一个发送单元，这样同样可以实现属于不同发送波束组的发送波束同时向接收端发送信号时能够被接收端同时接收。
可选的，上述实施方式，所述测量结果包括：
所述接收端对于所述N个发送波束中的每个发送波束的波束训练信号，均使用所述G个收发单元组进行接收测量，得到的所述G个收发单元组的测量结果，其中，每个收发单元组的测量结果包括使用该收发单元组对所述N个发送波束的波束训练信号进行接收测量的测量结果；
所述Q个发送波束包括：
所述接收端根据所述G个收发单元组的测量结果从所述N个发送波束中选择的Q个发送波束；
所述G个发送波束组，包括：
所述接收端根据所述G个收发单元组的测量结果将所述Q个发送波束划分的G个发送波束组。
该实施方式中，可以实现上述Q个发送波束是根据所述G个收发单元组的测量结果选择的，且上述G个收发单元组也是根据所述G个收发单元组的测量结果划分的。由于每个收发单元组的测量结果包括使用该收发单元组对N个发送波束的波束训练信号进行接收测量的测量结果，即每个收发单元组均对所有发送波束的波束训练信号进行接收测量，这样可以使得测量结果更加全面，从而可以选择出更优的Q个发送波束。例如：
对于发送端发送的N个发送波束中的每个发送波束的波束训练信号，所述接收端均可以使用所述G个收发单元组进行接收测量，得到所述G个收发单元组的测量结果；
所述接收端再根据所述G个收发单元组的测量结果从所述N个发送波束中选择Q个发送波束，以及将所述Q个发送波束划分为G个发送波束组。
其中，上述对于发送端发送的N个发送波束中的每个发送波束的波束训练信号，所述接收端均可以使用所述G个收发单元组进行接收测量可以是，对于每个发送波束的波束训练信号，均使用G个收发单元组进行接收测量， 即每个收发单元组均对所有发送波束的波束训练信号进行接收测量。
可选的，该实施方式中，上述Q个发送波束包括：
所述接收端在所述G个收发单元组的测量结果中，选择接收质量排在前Q位的Q个测量结果，并在所述N个发送波束中选择的所述Q个测量结果对应的Q个发送波束；
所述G个发送波束组包括：
所述接收端按照所述Q个发送波束在所述Q个测量结果中对应的收发单元组，将所述Q个发送波束划分的G个发送波束组。
该实施方式中，可以选择出接收质量排在前Q位的Q个测量结果对应的Q个发送波束，从而可以保持发送波束的接收质量，以提高数据传输质量。例如：接收端可以在所述G个收发单元组的测量结果中，选择接收质量排在前Q位的Q个测量结果，并在所述N个发送波束中选择所述Q个测量结果对应的Q个发送波束，以及按照所述Q个发送波束在所述Q个测量结果中对应的收发单元组，将所述Q个发送波束划分为G个发送波束组。
假设接收端有2个收发单元组，发送端有4个下行发送波束，则接收端一共有8个测量值，测量结果如下表所示(单位为dBm)：
表1：
  下行发送波束1 下行发送波束2 下行发送波束3 下行发送波束4
收发单元组1 -70 -68 -54 -80
收发单元组2 -82 -100 -72 -92
假设Q＝4，则接收质量最高的4个发送波束分别为：下行发送波束3(收发单元组1)，下行发送波束2(收发单元组1)，下行发送波束1(收发单元组1)，下行发送波束3(收发单元组2)。其中下行发送波束3出现了2次，分别对应收发单元组1和收发单元组2。即由于有多个收发单元组进行接收，在本公开实施例中，Q个发送波束中有可能存在重复的发送波束。
那么，G个发送波束分组则为两组，分别是：
第1组对应收发单元组1，其中的波束为：下行发送波束3，下行发送波束2，下行发送波束1。
第2组对应收发单元组2，其中的波束为：下行发送波束3。
可选的，上述实施方式中，上述Q个发送波束包括：
所述接收端对于每个收发单元组的测量结果，均选择接收质量在该接收单元组的测量结果中排在前Q g位的Q g个测量结果，得到Q个测量结果，并在所述N个发送波束中选择的所述Q个测量结果对应的Q个发送波束，其中，对于不同的收发单元组所述Q g为相同或者不同的正整数，且所述G个发送波束组对应的Q g之和为所述Q；
所述G个发送波束组包括：
所述接收端将每个收发单元组的Q g个测量结果对应的Q g个发送波束，划分与该收发单元组对应的发送波束组，而得到的G个发送波束组。
该实施方式中，可以实现每个收发单元组中选择Q g个测量结果对应的，得到Q个测量结果，这样可以为每个收发单元组选择接收质量最优的Q g个测量结果，从而提高接收端每个收发单元组的接收性能。例如：
对于每个收发单元组的测量结果，接收端均可以选择接收质量在该接收单元组的测量结果中排在前Q g位的Q g个测量结果，以得到Q个测量结果；接收端再可以在所述N个发送波束中选择所述Q个测量结果对应的Q个发送波束，以及将每个收发单元组的Q g个测量结果对应的Q g个发送波束，划分与该收发单元组对应的发送波束组。
需要说明的是，上述Q g可以是发送端预先配置给接收端，也可以是接收端自行决定的。且上述g＝1,2,…,G，例如：Q1＝Q2＝2，或者Q1＝2，Q2＝3等，但Q＝Q 1+Q 2+…+Q G。
具体的，接收端可以将第g个收发单元组对每个下行发送波束的测量结果进行排序，选择接收质量最高的Q g个下行发送波束，同样，这里不同的收发组选择的下行发送波束有可能有重复。
例如：仍然以表1中的测量结果为例，如果Q＝4，并且限定Q1＝Q2＝2，则波束选择和分组的结果为：
第1组对应收发单元组1，其中的波束为：下行发送波束3，下行发送波束2。
第2组对应收发单元组2，其中的波束为：下行发送波束3，下行发送波束1。
另外，本公开实施例中，发送波束的测量结果的接收质量可以通过参考信号接收功率(RSRP)表征，也可以用其他的测量表征，对此本公开实施例不作限定。且为了降低计算量接收端端在按照接收质量对发送波束进行排序时还可以设置一定的门限值，只有接收质量高于门限值的下行发送波束参与排序。
可选的，上述实施方式中，所述接收端中每个收发单元组包括至少一个收发单元，且每个收发单元包括至少一个接收波束，所述G个收发单元组的测量结果，包括：
对于所述N个发送波束中的每个发送波束的波束训练信号，所述接收端均使用所述G个收发单元组的各接收波束进行接收测量，得到所述G个收发单元组的测量结果集合，在所述G个收发单元组的测量结果集合中，选择的所述G个收发单元组的测量结果，其中，每个收发单元组的测量结果集合包括使用该收发单元组的各接收波束对所述N个发送波束的波束训练信号进行接收测量的测量结果；所述每个收发单元组的测量结果包括N个测量结果，该N个测量结果为该收发单元组的测量结果集合内每个发送波束对应的接收质量最高的测量结果。
该实施方式中，可以实现上述G个收发单元组的测量结果，是每个收发单元组内选择各每个发送波束对应的接收质量最高的测量结果，从而可以选择出更优的Q个发送波束。例如：针对收发单元组1，该收发单元组1包括接收波束1和2，那么，针对收发单元组1的测量结果集合就包括接收波束1对N个发送波束的测量结果，以及接收波束2对N个发送波束的测量结果；其中，针对发送波束1在收发单元组1的测量结果集合内接收质量最高的为接收波束1的测量结果，针对发送波束2在收发单元组1的测量结果集合内接收质量最高的为接收波束2的测量结果，那么，收发单元组1的测量结果为接收波束1对发送波束1的测量结果和接收波束2对发送波束2的测量结果。
针对于接收端可以是，对于发送端发送的N个发送波束中的每个发送波束的波束训练信号，接收端均可以使用所述G个收发单元组中的各接收波束进行接收测量，得到所述G个收发单元组的测量结果集合；接收端再在所述 G个收发单元组的测量结果集合中，选择所述G个收发单元组的测量结果。这样可以实现接收端针对每个发送波束的训练信号，均使用所有收发单元组内的所有接收波束进行接收测量，以选择出每个收发单元组内对各发送波束最优的测量结果。
另外，本公开实施例中，接收端可以共有
Figure PCTCN2018077114-appb-000008
个接收波束，每个接收波束对应一组波束赋形权值，第n个波束的接收波束赋形权值可以为
Figure PCTCN2018077114-appb-000009
其中L是波束赋形的天线单元数，可以小于接收端的天线单元数，例如L个天线单元接收到的信号经波束赋形权值加权后可以合并送到一个收发单元，以得相应的测量结果。
作为一种可选的实施方式，所述发送端接收所述接收端发送的所述N个发送波束中的Q个发送波束的标识信息，以及所述Q个发送波束中每个发送波束的分组信息，包括：
所述发送端接收所述接收端发送的所述N个发送波束中的Q个发送波束的标识信息，以及所述Q个发送波束中每个发送波束的分组信息和子分组信息，其中，每个发送波束组内对应相同接收波束的发送波束被划分成一个发送波束子组；
所述方法还包括：
所述发送端确定能够通过所述Q个发送波束中属于同一发送波束子组的发送波束，同时向所述接收端发送信号。
该实施方式中，可以实现获取Q个发送波束中各发送波束的分组信息和子分组信息，从而可以确定各发送波束所属的发送波束组，以及所属的发送波束子组，从而可以确定能够通过所述Q个发送波束中属于同一发送波束子组的发送波束，同时向所述接收端发送信号，即接收端能够被同时接收的发送波束归属为同一个波束子组。以及还可以确定所述Q个发送波束中属于不同发送波束组的发送波束，能够同时向所述接收端发送信号，这样可以确定出更多可以同时向所述接收端发送信号的发送波束，从而提高数据传输的效率。例如：发送波束1属于发送波束组1，发送波束2属于发送波束组1，发送波束3属于发送波束组1，且发送波束1和发送波束2属于发送波束子组1，发送波束4属于发送波束组2；那么，发送端就可以确定发送波束1和发送 波束2能够同时向所述接收端发送信号。且发送波束1和发送波束4能够同时向所述接收端发送信号，发送波束2和发送波束4能够同时向所述接收端发送信号，发送波束3和发送波束4能够同时向所述接收端发送信号。例如：如图3所示，发送波束(BT)1和发送波束(BT)2同时向接收端发送信号，且被接收端的收发单元(TXRU)0的接收波束(BR)1同时接收；又例如：如图4所示，发送波束(BT)1和发送波束(BT)4能够同时向所述接收端发送信号，且分别被接收端的收发单元(TXRU)0的接收波束(BR)1和收发单元(TXRU)1的接收波束(BR)2同时接收。
其中，该实施方式中，接收端可以是在所述接收端的候选接收波束中，为所述Q个发送波束均选择一个接收波束；对于每个发送波束组，所述接收端均将该发送波束组内对应相同接收波束的发送波束划分成一个发送波束子组；接收端向所述发送端发送所述N个发送波束中Q个发送波束的标识信息，以及所述Q个发送波束中每个发送波束的分组信息和子分组信息。其中，上述接收端的候选接收波可以是接收端中包括的接收波束，这个候选可以理解为发送端的发送波束对应的接收波束的候选者，即在候选接收波束中选择发送波束对应的接收波束，且这些候选接收波束可以是接收端预先配置的，或者用户设置，对此本公开实施例不作限定。
例如：对于第g组的Q g个下行发送波束，接收端进一步可以将其分为Pg个子组，第p个子组内的下行发送波束个数为R p,p＝1,2,…,P g。并且有R 1+R 2+…+R Pg<＝Q g。第g组内可以有发送波束不属于任何一个子组，即R 1+R 2+…+R Pg<Q g。如果第g个发送波束组内的任意两个波束都不能被接收端同时接收，则P g＝0，即第g组内没有划分出任何子组。如果第g个发送波束组内的一个波束不能和同一个发送波束组内任何其他波束被同时接收，则该发送波束不属于任何一个波束子组。或者可以约定一个特殊的子组，第g组内不能和任何其他波束被同时接收的波束皆分于该子组内。
例如：发送波束组1中包括发送波束1、发送波束2和发送波束3，其中，接收端为发送波束1、发送波束2和发送波束3分别选择接收波束1、接收波束1和接收波束2，则发送波束1和发送波束2对应相同接收波束1，从而接收端将发送波束1和发送波束2划分成一个发送波束子组。
可选的，该实施方式中，每个发送波束对应的接收波束，包括：
所述接收端的所有候选接收波束对该发送波束的波束训练信号的测量结果中，接收质量最高的测量结果对应的接收波束。
该实施方式中，可以实现每个发送波束对应的接收波束为，接收端的所有接收波束中对于该发送波束的接收质量最高的接收波束，从而提高数据传输的质量。
在该实施方式中，接收端可以是对于每个发送波束，接收端均可以获取所述接收端的所有候选接收波束对该发送波束的波束训练信号的测量结果，并将获取的测量结果中接收质量最高的测量结果对应的接收波束作为该发送波束的接收波束。
可选的，上述实施方式中，所述发送端接收所述接收端发送的所述N个发送波束中的Q个发送波束的标识信息，以及所述Q个发送波束中每个发送波束的分组信息和子分组信息，包括：
所述发送端接收所述接收端发送的G个发送波束组的分组信息，其中，每个发送波束组的分组信息包括该发送波束组内各子发送波束子组的发送波束子组信息，每个发送波束子组信息包括该发送波束子组内各发送波束的标识信息；或者
所述发送端接收所述接收端发送的所述Q个发送波束的波束划分信息，其中，每个发送波束的波束划分信息包括该发送波束的标识信息、该发送波束所属的发送波束组的分组标识和该发送波束所属的发送波束子组的子组标识。
其中，发送波束的标识信息可以是在系统内定义的每个波束对应的编号，或者是发送波束训练信号的索引，如资源索引，序列索引，时间索引，端口索引，以及它们之间的组合形式等，对此本公开实施例不作限定。
其中，上述第一种方式可以采用如下表2所示的形式。优选的，接收端还可以为每个分组及子组赋予唯一的标识，并将该标识一同上报。例如：每个发送波束组的分组信息还包括该发送波束组的组标识，每个发送波束子组信息还包括该发送波束子组的子组标识。具体可以参见图2，其中，发送波束标识(m,n,q)是第m个下行发送波束分组中第n个子组的第q个下行发送 波束的标识。
表2：
Figure PCTCN2018077114-appb-000010
Figure PCTCN2018077114-appb-000011
需要说明的是，分组标识和子组标识不必针对每个下行发送波束重复都上报，可以对属于同一个分组或者子组的下行发送波束上报一个共同的分组或者子组标识，从而减少传输开销。
上述第二种方式，接收端可以为每个分组及子组赋予唯一的标识，接收端上报的发送波束的波束划分信息如下表3所示：
表3：
Figure PCTCN2018077114-appb-000012
其中g i是第i个发送波束所属于的下行发送分组的标识，s i是第i个发送波束所属于的子组的标识，i＝1,2,…,Q,g i∈{1,2,…,G},s i∈{1,2,…,P gi}。
通过上述两种实施方式，可以实现灵活地向发送端上报各发送波束的分组信息和子组信息。
可选的，上述实施方式中，若所述G个发送波束组中存在目标发送波束组，所述目标发送波束组内包括目标发送波束，所述目标发送波束对应的接收波束与所述目标发送波束组内其他发送波束对应的接收波不同，所述目标发送波束的子组标识为空或者预设标识。这样可以实现对于不能和同一个分组内的任何其他波束被同时接收的下行发送波束，其子组标识为空(不属于任何子组)，或者给予一个特殊的子组标识，例如-1。从而让发送端能够准确确定哪些发送波束能够同时向接收端发送信号。
需要说明的是，本公开实施例介绍的多种可选的实施方式，彼此可以相 互结合实现，也可以单独实现。
本公开实施例，发送端向接收端发送N个发送波束的波束训练信号，所述N为正整数；所述发送端接收所述接收端发送的所述N个发送波束中的Q个发送波束的标识信息，以及所述Q个发送波束中每个发送波束的分组信息，其中，所述Q个发送波束包括G个发送波束组，所述G个发送波束组是所述接收端根据测量结果进行划分的，所述测量结果为所述接收端对所述发送端发送的波束训练信号进行接收测量得到的测量结果，所述Q和所述G均为正整数；所述发送端确定能够通过所述Q个发送波束中属于不同发送波束组的发送波束，同时向所述接收端发送信号。这样可以实现发送端可以确定能够同时向所述接收端发送信号的发送波束。
