本申请实施例涉及通信领域，并且具体地，涉及一种通信方法、终端设备和网络设备。
背景技术
在多波束系统中，终端设备可以通过一个接收波束接收网络设备通过多个发射波束发送的数据，为了保证数据的接收效果，多个发射波束分别与终端设备的接收波束组成的波束对对应的信道质量要满足一定的条件，如果发射波束与接收波束组成的波束对对应的信道质量较差的话就不利于数据的接收。而为了保证发射波束与接收波束组成的波束对对应的信道质量能够满足要求，需要终端设备上报波束对对应的信道质量的情况，因此，如何上报波束对对应的信道质量是一个需要研究的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
本申请实施例的方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、LTE系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、NR(New Radio Access Technology)、 5G等。
还应理解，在本申请实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)等，该终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本申请实施例中，网络设备可以是接入网设备，例如可以是基站、发射和接收点(Transmit and Receive Point，TRP)或接入点，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(evolved Node B，eNB或e-NodeB)，还可以是NR或5G的基站(gNB)，本申请实施例对此不作具体限定。另外，这里的5G系统或网络还可以称为新无线(New Radio，NR)系统或网络。
下面先结合图1和图2对本申请实施例可能的应用场景进行简单的介绍。
图1示出了本申请实施例应用的无线通信系统100。该无线通信系统100可以包括网络设备110，以及位于该网络设备覆盖范围内的至少一个终端设备120。网络设备110可以通过发射波束向终端设备120发送数据，终端设备120可以通过接收波束接收网络设备110发送的数据。
图2示出了本申请实施例的发射波束和接收波束的示意图，在图2中，网络设备有4个发射波束，终端设备有2个接收波束，网络设备可以通过这4个发射波束向终端设备发送数据，终端设备可以通过两个接收波束接收网络设备通过4个发射波束发送的数据。在传输数据时，通常每个发射波束对应的都有一个最佳接收波束，例如，发射波束T1对应的最佳接收波束为R1，发射波束T2对应的最佳接收波束为R2，如果采用接收波束R2接收发射波束T1发送的数据，那么接收效果会比较差，同样，如果采用接收波束R1接收发射波束T2发送的数据，那么接收效果也会比较差。如果采用接收波束R1接收发射波束T1和T2发送的数据，那么终端设备从T1接收数据的效果较好，但是从T2接收的数据的效果比较差，当发射波束T1和发射波束 T2对应的最佳接收波束均是R1时，采用接收波束R1接收发射波束T1和T2接收数据的效果较好。
当需要采用多个发射波束向终端设备联合传输数据时，例如，在图2中，当采用发射波束T1和T2联合传输数据时，终端设备只能采用一个接收波束接收发射波束T1和T2发送的数据，而这时T1和T2要分别与R1组成的波束对对应的信道质量较好，或者，T1和T2要分别与R2组成的波束对对应的信道质量较好，这样才能采用发射波束T1和T2向终端设备联合传输数据。
同样，以图2为例，当网络设备在发射波束T1和T2上分别向终端设备传输下行控制信息和下行数据时，如果终端设备分别在接收波束R1和R2上接收终端设备发送的下行控制信息和下行数据时，由于终端设备需要在接收波束R1上解调完下行控制信息之后将接收波束切换到R2来接收网络设备发送的下行数据，这需要一定的切换时间，很可能导致丢失部分下行数据。因此，在这种情况下终端设备也需要采用一个接收波束来接收两个发射波束T1和T2发送的下行控制信息和下行数据。
在通过多个波束联合传输数据的情况下，以及通过不同的波束分别传输控制信息和数据时的情况下都需要对发射波束进行分组，并且被分配到一组的发射波束可以对应同一个接收波束，利用该接收波束接收这一组发射波束的数据时接收的效果较好。
但是网络设备把哪些发射波束分成一组取决于终端设备上报的波束对的信息，下面就结合附图对本申请实施例中如何上报波束对的信息进行详细的描述。
图3是本申请实施例的通信方法的示意性流程图。图3的方法包括：
310、终端设备确定网络设备的M个发射波束与所述终端设备的N个接收波束组成的M×N个波束对对应的信道质量。
例如，如图4所示，网络设备包括3个收发点和接收点(Transmit and Receive Point，TRP)，TRP1、TRP2和TRP3，其中，TRP1包括发射波束T1和T2，TRP2包括发射波束T3和T4，TRP3包括发射波束T5和T6。终端设备包括两个接收波束R1和R2。在图4中，网络设备一共有6个发射波束，终端设备一共有2个接收波束，网络设备的发射波束与终端设备的接收波束一共组成12个波束对。终端设备在通过不同的接收波束接收网络设备通过不同的发射波束发送的信号时，接收到信号的效果并不相同，也就是说 不同的波束对对应的信道质量不同。应理解，在图4中，每两个发射波束对应于一个TRP，事实上，在本申请实施例中，M个发射波束可以对应于同一个TRP，也可以对应于多个不同的TRP。
可选地，终端设备可以通过测量以不同接收波束来接收网络设备各个发射波束发送的测量信号的信号质量来确定上述M×N个波束对对应的信道质量。
具体地，以图4为例，终端设备可以先以接收波束R1来分别接收网络设备通过6个发射波束发送的测量信号，接下来，终端设备再以接收波束R2来接收网络设备通过6个发射波束发送的测量信号，并对接收到的测量信号进行测量以得到各个波束对对应的信道质量。
320、终端设备在M×N个波束对中确定L个波束对，其中，L个波束对中的任意一个波束对对应的信道质量大于或者等于所述M×N个波束对中除所述L个波束对之外的其它波束对对应的信道质量，其中，M和N为大于1的整数，L为小于M×N的整数。
可选地，上述L可以是预先配置的数值。也就是说终端设备可以按照信道质量在全部的波束对中选择一定数量的对应信道质量较好的波束对。L的大小可以是通信协议中规定的数值，也可以是网络设备为终端设备配置的数值，具体地，L可以是网络设备为终端设备静态配置(例如，可以在终端设备刚接入网络时就为终端设备配置)的数值，也可以是在终端设备需要上报波束对对应的信道质量之前通过指示信息为终端设备动态配置的数值。另外，应理解，上述L也可以等于M×N。
330、终端设备向网络设备发送上述L个波束对的标识信息。
应理解，终端设备可以自发地向网络设备发送波束对的标识信息，例如，终端设备可以周期性地向网络设备上报波束对的标识信息。
另外，终端设备也可以在收到网络设备的指示信息后再向网络设备发送波束对的标识信息。具体地，终端设备接收网络设备发送的上报指示信息，该上报指示信息用于指示终端设备向网络设备发送网络设备的发射波束与终端设备的接收波束组成的波束对的标识信息。在接收到该上报指示信息后，终端设备再向网络设备发送波束对的标识信息。
可选地，终端设备可以向网络设备发送上述L个波束对对应的信道质量信息。
应理解，终端设备在向网络设备上报信息时，可以只上报上述L个波束对的标识信息，也可以既上报L个波束对的标识信息，也上报L个波束对对应的信道质量信息。
以图4为例，终端设备可以按照信道质量在12个波束对中选择出对应的信道质量最好的6个波束对，并将该6个波束对的标识信息发送给网络设备。在图4中，发射波束的标识分别为T1、T2、T3、T4、T5和T6，接收波束的标识分别为R1和R2，终端设备上报的波束对的标识信息的具体可以是[T3 R1]、[T4 R1]、[T3 R2]、[T4 R2]、[T1 R1]和[T2 R2](当然，这里仅仅以这些波束对为例来说明标识信息，终端设备也可以上报其它6个波束对的标识信息)。
下面仍以图4为例对现有技术和本申请实施例的通信方法进行详细的介绍。在图4中，假设发射波束B1、B2、B5和B6与接收波束组成的波束对的信道质量较差，而只有发射波束B3和B4与接收波束组成的波束对的信道质量较好，其中，发射波束B3和B4与接收波束R1和R2组成的波束对对应的信道质量如下：
[B3 R1]1
[B3 R2]0.9
[B4 R1]0.8
[B4 R2]1
在现有技术中，终端设备只上报对应的信道质量较好的发射波束以及与该发射波束的最佳接收波束，具体地，终端设备只向网络设备上报波束对[B3 R1]和[B4 R2]的相关信息。当网络设备需要通过多个发射波束向终端设备的一个接收波束传输数据时，网络设备需要对发射波束进行分组，但是由于网络设备获取的信息非常有限(发射波束B3的最佳接收波束是R1，发射波束B4的最佳接收波束是R2)，不能根据这些有限的信息将波束B3和B4划分成一组，进而在某些情况下无法实现采用多个发射波束向终端设备的同一个接收波束传输数据。
而在本申请实施例中，终端设备在选择要上报的波束对时根据的是各个波束对对应的信道质量，并从中选择对应信道质量较好的波束对，例如，具体地，终端设备可以将[B3 R1]、[B3 R2]、[B4 R1]以及[B4 R2]上报给网络设备，由于发射波束B3、B4与接收波束组成的波束对对应的信道质量都比较 好，因此，在需要采用两个发射波束联合向终端设备的同一个接收波束传输数据时，网络设备可以将B3和B4分成一组，并且这一组发射波束对应的接收波束既可以是接收波束R1也可以是接收波束R2。因此，本申请实施例中的通信方法与现有技术相比能够更好地上报波束对的信息，便于网络设备根据上报的波束对的信息对发射波束进行分组。
本申请实施例中，终端设备能够直接从全部波束对中选择信道质量较好的部分波束对，并将该部分波束对的标识信息上报给网络设备，使得网络设备能够获得信道质量较好的波束对的标识信息，并根据这些波束对的标识信息对发射波束进行合理的分组。
可选地，终端设备在确定L个波束对时可以先根据信道质量的大小对所述M×N个波束对进行排序，接下来，再根据排序结果在M×N个波束对中确定所述L个波束对。
在对M×N个波束对进行排序时可以按照信道质量从大到小的顺序，也可以按照信道质量从小到大的顺序进行，在排序完成后终端设备可以从所有的波束对中选择信道质量最好的L个波束对。例如，发射波束和接收波束一共组成10个波束对，那么可以先对这10个波束对按照信道质量从大到小进行排序后，然后再从这10个波束对中选择前5个对应信道质量较好的波束对。
可选地，终端设备在确定L个波束对时还可以按照波束对对应的信道质量与预设阈值的关系来选择L个波束对，例如，终端设备可以在上述M×N个波束对中选择信道质量大于第一阈值的L个波束对。在这种情况下，终端可以不按照波束对的信道质量对波束对进行排序，而是直接将各个波束对对应的信道质量与第一阈值进行比较，将对应信道质量大于第一阈值的波束对的信息上报即可，当然，终端设备也可以按照波束对的信道质量对波束对进行排序，然后再将各个波束对的信道质量与第一阈值进行比较，接下来再上报对应的信道质量大于第一阈值的波束对的信息。
如图4所示，网络设备的6个发射波束与终端设备的2个接收波束可以组成12个波束对，终端设备在确定要上报的波束对的信息之前，可以先对这12个波束对对应的信道质量进行排序，排序结果如下：
[T2 R1]1
[T3 R2]1
[T5 R1]0.9
[T6 R2]0.9
[T5 R2]0.8
[T6 R1]0.8
[T4 R2]0.2
[T1 R1]0.2
[T1 R2]0.1
[T2 R2]0.1
[T3 R1]0.1
[T4 R1]0.1
终端设备可以采用以下两种方式来确定要上报的波束对：
第一种方式：终端设备选择对应信道质量最好的6个波束对(此时L为6)，这6个波束对以及这6个波束对对应的信道质量如下：
[T2 R1]1
[T3 R2]1
[T5 R1]0.9
[T6 R2]0.9
[T5 R2]0.8
[T6 R1]0.8
第二种方式：终端设备选择信道质量大于0.8的波束对(当第一阈值为0.8时对应的L为4，当第一阈值为小于0.8且大于0.2时对应的L为6)，这4个波束对以及这4个波束对对应的信道质量如下：
[T2 R1]1
[T3 R2]1
[T5 R1]0.9
[T6 R2]0.9
应理解，在采用上述两种方式选择要上报的波束对之前可以按照信道质量对波束对进行排序，也可以不对波束对对应的信道质量进行排序而是直接选择要上报的波束对。
图5是本申请实施例的通信方法的示意性流程图。图5的方法包括：
510、终端设备在网络设备的M个发射波束中确定L个发射波束，
其中，L个发射波束中的任意一个发射波束与任意一个发射波束对应的第一接收波束组成的波束对对应的信道质量大于或者等于M个发射波束中除L个发射波束之外的其它发射波束与其它发射波束的第一接收波束组成的波束对对应的信道质量，其中，第一接收波束为接收发射波束发送的信号的质量满足预设阈值的接收波束或者接收发射波束发送的信号的质量最好的接收波束。
可选地，上述L可以是预先配置的数值。也就是说终端设备可以按照信道质量在全部的波束对中选择一定数量的对应信道质量较好的波束对。L的大小可以是通信协议中规定的数值，也可以是网络设备为终端设备配置的数值，具体地，L可以是网络设备为终端设备静态配置(例如，可以在终端设备刚接入网络时就为终端设备配置)的数值，也可以是在终端设备需要上报波束对对应的信道质量之前通过指示信息为终端设备动态配置的数值。另外，应理解，上述L也可以等于M×N。
应理解，终端设备可以从全部的发射波束中选择出对应信道质量较好的L个发射波束，该L个发射波束与第一接收波束组成的波束对对应的信道质量较好。
例如，如图4所示，共有6个发射波束，终端设备从发射波束T3和T4接收到的信号的质量大于终端设备从发射波束T1、T2、T5和T6接收到的信号的质量，那么终端设备可以从中选择出T3和T4这两个发射波束。
下面以发射波束T3为例对最佳接收波束进行说明，T3可以对应接收波束R1和R2，那么，只要[T3 R1]对应的信道质量大于[T3 R2]对应的信道质量，那么T3的最佳接收波束是R1。
520、终端设备在L个发射波束中的每个发射波束与N个接收波束组成的N个波束对中确定K个波束对，其中，K个波束对对应的信道质量大于N个波束对中除K个波束对之外的其它波束对对应的信道质量，其中，M和N为大于1的整数，L为小于M的整数，K为小于N的整数。
可选地，上述K可以是预先配置的数值。K的大小可以是通信协议中规定的数值，也可以是网络设备为终端设备配置的数值，具体地，K可以是网络设备为终端设备静态配置(例如，可以在终端设备刚接入网络时就为终端设备配置)的数值，也可以是在终端设备需要上报波束对对应的信道质量之前通过指示信息为终端设备动态配置的数值。另外，应理解，上述K也可以 等于N。
应理解，终端设备会从L个发射波束中的每个发射波束与接收波束组成的所有波束对中选择K个波束对，假设，一共有3个发射波束，那么终端设备会分别从这3个发射波束中的每一个发射波束与接收波束组成的所有波束对中选择K个波束对，另外，对于不同的发射波束来说K的取值可以不同，例如，可以从第一发射波束与接收波束组成的所有波束对中选择3个波束对(此时K取值为3)，而对于第二发射波束来说，可以从该第二发射波束与接收波束组成的所有波束对中选择2个波束对(此时K取值为2)。
530、终端设备向网络设备发送每个发射波束对应的K个波束对的标识信息。
应理解，终端设备可以自发地向网络设备发送波束对的标识信息，例如，终端设备可以周期性地向网络设备上报波束对的标识信息。
另外，终端设备也可以在收到网络设备的指示信息后再向网络设备发送波束对的标识信息。具体地，终端设备接收网络设备发送的上报指示信息，该上报指示信息用于指示终端设备向网络设备发送网络设备的发射波束与终端设备的接收波束组成的波束对的标识信息。在接收到该上报指示信息后，终端设备再向网络设备发送波束对的标识信息。
在本申请实施例中，终端设备不仅上报接收测量信号较好的发射波束对应的最佳接收波束的信息，而且还可以上报发射波束对应的其它接收波束的信息，上报的波束对的信息更加全面，使得网络设备能够根据终端设备上报的波束对的信息对波束对进行合理的分组。
可选地，终端设备在确定上述K个波束对时可以先按照信道质量的大小对每个发射波束对应的N个波束对进行排序，接下来，终端设备再根据排序结果在N个波束对中确定所述K个波束对。
在对N个波束对进行排序时可以按照信道质量从大到小的顺序，也可以按照信道质量从小到大的顺序进行，在排序完成后终端设备可以从所有的波束对中选择信道质量最好的K个波束对。例如，某个发射波束与所有的接收波束一共组成5个波束对，那么可以先对这5个波束对按照信道质量从大到小进行排序后，然后再从这5个波束对中选择前3个对应信道质量较好的波束对。
可选地，终端设备在确定上述K个波束对时还可以直接在N个波束中 确定信道质量大于第一阈值的K个波束对。在这种情况下，终端可以不按照波束对的信道质量对波束对进行排序，而是直接将各个波束对对应的信道质量与第一阈值进行比较，将对应信道质量大于第一阈值的波束对的信息上报即可，当然，终端设备也可以按照波束对的信道质量对波束对进行排序，然后再将各个波束对的信道质量与第一阈值进行比较，接下来再上报对应的信道质量大于第一阈值的波束对的信息。
终端设备在确定上述K个波束对时，既可以从N个波束对中直接按照质量选择一定数量的波束对，也可以将N个波束对对应的信道质量与预设的阈值进行比较，也就是说终端设备在确定K个波束对可以只考虑数量，也可以只考虑波束对与预设阈值的大小关系。当然，终端设备在确定K个波束对时也可以同时考虑数量以及波束对对应的信道质量与预设阈值的关系。
下面以图6为例对本申请实施例中的通信方法进行详细的描述。在图6中，共有T1、T2、T3和T4这4个发射波束，以及R1、R2和R3这三个接收波束，发射波束和接收波束一共组成了12个波束对。其中，发射波束T3和T4与各自的最佳接收波束组成的波束对对应的信道质量大于发射波束T1和T2与各自的最佳接收波束组成的波束对对应的信道质量。
终端设备从全部的发射波束中确定出发射波束T3和T4，接下来再确定上报这两个发射波束对应的波束对。下面以发射波束T3为例对确定每个发射波束的波束对进行详细的说明。
发射波束T3一共对应3个接收波束，T3与这3个接收波束一共组成3个波束对，在从这3个波束对中确定要上报的波束对时，可以先对这三个波束对对应的信道质量按照从大到小进行排序，排序结果如下所示：
[T3 R1]1
[T3 R2]0.8
[T3 R3]0.5
接下来，终端设备可以从这3个波束对中选择2个波束对[T3 R1]和[T3 R2]进行上报(此时K的取值为2)。
或者，终端设备还可以从这3个波束对中选择对应的信道质量大于0.5的两个波束对[T3 R1]和[T3 R2]进行上报。
或者，终端设备还可以从这3个波束对中选择2个对应信道质量较好的波束对[T3 R1]和[T3 R2]，然后再从这2个波束对中选择对应信道质量大于 0.9的波束对[T3 R1]，并进行上报。或者，终端设备先从这3个波束对中选择出对应信道质量大于0.5的2个波束对([T3 R1]和[T3 R2])，然后再从中选择1个对应信道质量更好的波束对[T3 R1]进行上报。
