请参考图1，其示出了本发明一个实施例提供的移动通信系统的结构示意图。该移动通信系统可以是5G系统，又称NR系统。该移动通信系统包括：接入网设备120和终端140。
接入网设备120可以是基站。例如，基站可以是5G系统中采用集中分布式架构的基站(gNB)。当接入网设备120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media  Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本发明实施例对接入网设备120的具体实现方式不加以限定。
接入网设备120和终端140通过无线空口建立无线连接。可选地，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口(New Radio，NR)；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
终端140可以是指向用户提供语音和/或数据连通性的设备。终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端140可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，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。例如，订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户装置(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户终端(User Equipment)。
需要说明的是，在图1所示的移动通信系统中，可以包括多个接入网设备120和/或多个终端140，图1中以示出一个接入网设备120和一个终端140来举例说明，但本实施例对此不作限定。
在5G系统中，发送端设备可以通过波束向特定方向上的接收端设备发送数据。其中，发送端设备可以是上述图1所示的移动通信系统中的接入网设备120，接收端设备可以是终端140，此时，发送端设备向接收端设备发送的波束可以称为下行波束；或者，发送端设备也可以是上述图1所示的移动通信系统中的终端140，而接收端设备可以是接入网设备120，此时，发送端设备向接收端设备发送的波束可以称为上行波束。
发送端设备发送的不同波束的宽度可以不同。比如，在本发明实施例中，发送端设备发送的波束可以分为第一波束和第二波束两种。可选地，一个第一波束覆盖至少一个第二波束。
在本发明所示的方案中，第一波束覆盖至少一个第二波束，指的是第一波束在空间上覆盖至少一个第二波束，或者说，至少一个第二波束的覆盖范围处于第一波束的覆盖范围内。其中，在某些场景下，第一波束可以被称为宽波束， 第二波束可以被称为窄波束，或者，第一波束可以被称为大波束，第二波束可以被称为小波束，本发明实施例对于第一波束和第二波束的具体命名不做限定。
其中，不同类型的波束可以传输不同的物理信道。比如，第二波束可以用于传输数据信道，这样用于传输数据信道的波束数量更多，可以更好的实现空分复用，提高系统容量；而第一波束可以用于传输公共信道或控制信道，以增加公共信道或控制信道的覆盖性。当然，本发明实施例并不限定不同类型波束所传输的物理信道，比如，在实际应用中，第一波束也可以用于传输数据信道，第二波束也可以用于传输公共信道或控制信道。在另一种可能的实现方式中，上述第一波束也可以不对应特定的物理信道。
具体的，请参考图2，其示出了本发明实施例提供的波束的示意图。如图2所示，发送端设备发送6个波束，分别为波束1至波束6，波束1至波束4为第二波束，即窄波束；波束5和波束6为第一波束，即宽波束。并且，波束5覆盖波束1和波束2，波束6覆盖波束3和波束4。其中，发送端设备可以通过波束1至波束4发送数据信道的数据，并通过波束5和波束6发送控制信道的数据。
其中，图2所示的示意图是以发送端设备发送6个波束，且一个第一波束覆盖两个第二波束为例进行说明，在实际应用中，发送设备发送的波束的数量并不限定为6个，且一个第一波束覆盖的第二波束的数量也不限于2个，即发送设备发送的波束的数量可以更多或更少，而一个第一波束覆盖的第二波束的数量也可以更多或更少。比如，请参考图3，其示出了本发明实施例提供的一种波束的示意图，如图3所示，发送端设备发送12个波束，分别为波束1至波束12，波束1至波束9为第二波束，即窄波束；波束10至波束12为第一波束，即宽波束。并且，波束10覆盖波束1至波束3，波束11覆盖波束4至波束6，波束12覆盖波束7至波束9。
请参考图4，其示出了本发明一个实施例提供的波束选择方法的方法流程图。本实施例以该波束选择方法应用于图1所示的移动通信系统中来举例说明。该方法包括：
步骤401，发送端设备生成至少一组波束对应信息，每组波束对应信息中包含一个第一波束与至少一个第二波束之间的对应关系。
其中，第一波束和第二波束可以是发送端设备发送的波束，并且，第一波束覆盖对应的至少一个第二波束。
可选的，发送端设备在生成波束对应信息时，根据自身发送的第一波束与第二波束之间的覆盖关系生成波束对应信息，即生成第一波束以及第一波束覆盖的至少一个第二波束之间的对应关系。
比如，以图2为例，在图2中，波束5覆盖波束1和波束2，波束6覆盖波束3和波束4，发送端设备可以将波束5与波束1和波束2之间的对应关系生成为一组波束对应信息，并将波束6与波束3和波束4之间对应关系生成为另一组波束对应信息。
或者，以图3为例，在图3中，波束10覆盖波束1至波束3，波束11覆盖波束4至波束6，波束12覆盖波束7至波束9，则发送端设备可以将波束10与波束1至波束3之间的对应关系生成为一组波束对应信息，将波束11与波束4至波束6之间对应关系生成为另一组波束对应信息，并将波束12与波束7至波束9之间的对应关系生成为另一组波束对应信息。
在本发明实施例中，一组波束对应信息中的第一波束与至少一个第二波束之间的对应关系可以是显性的对应关系，也可以是隐性的对应关系。
其中，显性的对应关系可以是第一波束与至少一个第二波束的波数ID(beam ID)之间的对应关系。
或者，上述隐性的对应关系是第一波束对应的物理资源与至少一个第二波束各自对应的物理资源之间的对应关系。其中，上述物理资源可以是时域资源、频域资源以及码域资源中的至少一种。
和/或，上述隐性的对应关系是第一波束对应的参考信号与至少一个第二波束各自对应的参考信号之间的对应关系。
和/或，上述隐性的对应关系是第一波束对应的物理资源与至少一个第二波束各自对应的参考信号之间的对应关系。
和/或，上述隐性的对应关系是第一波束对应的参考信号与至少一个第二波束各自对应的物理资源之间的对应关系。
当然，在实际应用中，一组波束对应信息中的第一波束与至少一个第二波束之间的对应关系也可以同时包含上述显性的对应关系和隐性的对应关系。换句话说，对于一组对应关系，同时以显性对应关系和隐性对应关系两种形式进行指示。
可选的，在本发明实施例中，当第一波束和第二波束分别用于传输不同的物理信道时，上述第一波束与至少一个第二波束之间的对应关系中还包含至少一个第二波束对应的第一物理信道，以及，第一波束对应的第二物理信道。
具体的，上述第一波束与至少一个第二波束之间的对应关系中包含：至少一个第二波束对应的第一物理信道的标识，以及，第一波束对应的第二物理信道的标识。
或者，上述第一波束与至少一个第二波束之间的对应关系中包含：至少一个第二波束对应的第一物理信道的信道类型，以及，第一波束对应的第二物理信道的信道类型。
比如，以第二波束用于传输数据信道，第一波束用于传输控制信道为例，当上述第一波束和第二波束为下行波束，比如，发送端设备是接入网设备，接收端设备是终端时，第一物理信道是下行数据信道，第二物理信道是下行控制信道；相应的，当上述第一波束和第二波束为上行波束，比如，发送端设备是终端，接收端设备是接入网设备时，第一物理信道是上行数据信道，第二物理信道是上行控制信道，发送端设备通过波束对应信息向接收端设备指示第一波束对应的物理信道以及第二波束对应的物理信道。
可选的，当上述第一波束和第二波束为上行波束时，在上述隐性对应关系中使用的参考信号包括：对应的波束传输的上行物理信道所使用的DMRS，和/或，对应的波束传输的上行物理信道所使用的SRS。
或者，当上述第一波束和第二波束为下行波束时，在上述隐性对应关系中使用的参考信号包括：对应的波束传输的下行物理信道所使用的DMRS，和/或，对应的波束的beam specific RS，和/或，对应的波束的CSI-RS。
在实际应用中，在隐性对应关系中所使用的参考信号并不限定于上述DMRS、SRS、beam specific RS以及CSI-RS这四种，发送端设备也可以按照实际的使用场景选择其它的参考信号来指示第一波束和第二波束之间的对应关系。同时，这些参考信号也可以采用具有相同或相似的导频功能，但名称不同的其它参考信号代替。
步骤402，发送端设备向接收端设备发送至少一组波束信息。
可选的，发送端设备通过专用信令或广播信令发送该至少一组波束对应信息。比如，当发送端设备是接入网设备时，发送端设备可以通过专用信令或广播信令发送该至少一组波束对应信息；当发送端设备是终端时，发送端设备可 以通过专用信令发送该至少一组波束对应信息。
其中，上述专用信令可以是无线资源控制(Radio Resource Control，RRC)信令等信令，上述广播信令可以是系统信息广播等信令。
步骤403，接收端设备接收发送端设备发送的至少一组波束信息。
相应的，接收端设备接收发送端设备通过专用信令或广播信令发送的该至少一组波束对应信息。比如，当发送端设备是接入网设备时，接收端设备可以通过专用信令或广播信令接收该至少一组波束对应信息；当发送端设备是终端时，接收端设备可以通过专用信令接收该至少一组波束对应信息。
步骤404，接收端设备根据至少一组波束对应信息，从发送端设备发送的各个波束中选择接收的波束。
在本发明实施例中，接收某个波束可以是指接收通过该波束传输的物理信道中的数据或信令，相应的，下文涉及的接收某个信道可以是指接收该信道中的数据或信令。
在本发明实施例中，接收端设备根据至少一组波束对应信息，从发送端设备发送的各个波束中选择接收的波束的场景，可以包括但不限于以下三种：
第一，接收端设备通过第二波束接收第一物理信道时，可以根据至少一组波束对应信息，将该第二波束对应的第一波束选择为用于接收第二物理信道的波束。
比如，以第一波束用于传输控制信道，第二波束用于传输数据信道为例，当接收端设备正在通过一个第二波束接收数据信道时，若接收端设备需要接收控制信道，则可以根据接收到的波束对应信息快速选择与该第二波束相对应的第一波束，不需要对发送端设备发送的各个第一波束分别进行测量，从而减少了数据接收过程中对波束的信号质量进行测量的步骤。
第二，接收端设备通过第一波束接收第二物理信道时，根据至少一组波束对应信息，测量该第一波束对应的至少一个第二波束的信号质量，并将第一波束对应的至少一个第二波束中，信号质量最好的第二波束选择为用于接收第一物理信道的波束。
比如，以第一波束用于传输控制信道，第二波束用于传输数据信道为例，当接收端设备正在通过第一波束接收控制信道时，若接收端设备需要接收数据信道，则可以根据接收到的波束对应信息，确定与第一波束相对应的部分第二波束，并从确定的部分第二波束中选择出信号质量最好的第二波束进行数据信 道的接收，不需要对发送端设备发送的所有第二波束分别进行测量，从而减少了数据接收过程中对波束的信号质量进行测量的次数。
第三，当至少一组波束对应信息为至少两组波束对应信息时，接收端设备测量至少两组波束对应信息各自的第一波束的信号质量，继而测量至少两组波束对应信息各自的第一波束中，信号质量最好的第一波束对应的至少一个第二波束的信号质量，并将信号质量最好的第一波束对应的至少一个第二波束中，信号质量最好的第二波束选择为接收的波束。
通过上述方法，当发送端设备向接收端设备所在的方向上发送多个第二波束时，接收端设备不需要对该多个第二波束中的每一个第二波束进行信号质量的测量，只需要先对覆盖该多个第二波束的第一波束进行测量，找出其中信号质量最好的第一波束，而该信号质量最好的第一波束所覆盖的至少一个第二波束即可以被认为是信号质量最好的一组第二波束，接收端设备再对该信号质量最好的一组第二波束进行测量并选择出信号质量最好的第二波束，本方案相比于对每一个第二波束分别进行信号质量的测量来说，能够减少数据接收过程中对波束的信号质量进行测量的次数。
综上所述，本发明实施例所示的波束选择方法，发送端设备将第一波束与第二波束之间的对应关系发送给接收端设备，接收端设备在接收发送端设备发送的数据的过程中，可以根据该第一波束与第二波束之间的对应关系，从发送端设备发送的各个波束中快速选择接收的波束，减少了数据接收过程中对波束的信号质量进行测量的步骤或次数，从而减少波束测量所耗费的时间，加速接收端设备的波束测量和选择的过程，简化数据接收的复杂度，降低数据接收的时延。
需要说明的是，上述图4所示实施例中由接收端设备执行的步骤可以单独实现成为接收端设备侧的波束选择方法，上述各个实施例中由发送端设备执行的步骤可以单独实现成为发送端设备侧的波束选择方法。
请参考图5，其示出了本发明一个实施例提供的波束选择方法的方法流程图。本实施例以该波束选择方法应用于图1所示的移动通信系统中，发送端设备为接入网设备，接收端设备为终端，且接入网设备通过第二波束发送下行数据信道，通过第一波束发送下行控制信道来举例说明。该方法包括：
步骤501，接入网设备生成至少一组波束对应信息，每组波束对应信息中包含一个第一波束与至少一个第二波束之间的对应关系。
可选的，在本发明实施例中，上述第一波束与至少一个第二波束之间的对应关系中还包含至少一个第二波束对应的下行数据信道，以及，第一波束对应的下行控制信道。
或者，上述第一波束与至少一个第二波束之间的对应关系中也可以包含至少一个第二波束对应的上行物理信道的标识或信道类型，以及，第一波束对应的上行物理信道的标识或信道类型。
步骤502，接入网设备向终端发送至少一组波束信息。
可选的，接入网设备通过专用信令或广播信令发送该至少一组波束对应信息。
步骤503，终端接收接入网设备发送的至少一组波束信息。
相应的，终端通过专用信令或广播信令接收该至少一组波束对应信息。
步骤504，终端通过第二波束接收下行数据信道时，将第二波束对应的第一波束选择为用于接收下行控制信道的波束。
比如，以接入网设备发送的波束如图2所示为例，接入网设备通过第二波束(波束1至波束4)传输下行数据信道，并通过第一波束(波束5和波束6)传输下行控制信道，当终端正在通过波束1接收下行数据信道时，此时，若终端需要接收下行控制信道，不需要对波束5和波束6分别进行测量，直接根据接收到的波束对应信息，快速选择与波束1相对应的第一波束，即波束5，并通过波束5接收下行控制信道。
综上所述，本发明实施例提供的波束选择方法，接入网设备通过第二波束传输下行数据信道，通过第一波束传输下行控制信道，并向终端通知其发送的第一波束与第二波束之间的对应关系，终端在通过第二波束接收接入网设备传输的下行数据信道时，若需要接收下行控制信道，则可以根据第一波束与第二波束之间的对应关系，直接通过该第二波束对应的第一波束接收下行控制信道，不需要对接入网设备发送的各个第一波束进行测量，从而减少了接收下行控制信道过程中，对波束的信号质量进行测量的步骤。
在基于图5的可选实施例中，终端也可以通过接入网设备发送的第一波束与第二波束之间的对应关系，选择用于接收下行数据信道的第二波束，此时， 上述步骤504可以替换实现为步骤504a和步骤504b，如图6所示：
步骤504a，终端通过第一波束接收下行控制信道时，根据至少一组波束对应信息，测量该第一波束对应的至少一个第二波束的信号质量。
比如，以接入网设备发送的波束如图2所示为例，接入网设备通过第二波束(波束1至波束4)传输下行数据信道，并通过第一波束(波束5和波束6)传输下行控制信道，当终端正在通过波束5接收下行控制信道时，此时，若终端需要接收下行数据信道，则根据接收到的波束对应信息，选择对与波束5相对应的第二波束(波束1和波束2)进行信号质量的测量，不需要对波束3和波束4分别进行测量。
步骤504b，终端将第一波束对应的至少一个第二波束中，信号质量最好的第二波束选择为用于接收下行数据信道的波束。
比如，终端对波束1和波束2分别进行信号质量的测量后，选择通过波束1和波束2中信号质量最好的波束接收下行数据信道。
综上所述，本发明实施例提供的波束选择方法，接入网设备通过第二波束传输下行数据信道，通过第一波束传输下行控制信道，并向终端通知其发送的第一波束与第二波束之间的对应关系，终端在通过第一波束接收接入网设备传输的下行控制信道时，若需要接收下行数据信道，则可以根据第一波束与第二波束之间的对应关系，仅对第一波束对应的第二波束进行测量，不需要对接入网设备发送的所有第二波束分别进行测量，从而减少了接收下行数据信道中的数据过程中，对波束的信号质量进行测量的次数。
请参考图7，其示出了本发明一个实施例提供的波束选择方法的方法流程图。本实施例以该波束选择方法应用于图1所示的移动通信系统中，发送端设备为接入网设备，接收端设备为终端来举例说明。该方法包括：
步骤701，接入网设备生成至少两组波束对应信息，每组波束对应信息中包含一个第一波束与至少一个第二波束之间的对应关系。
在本发明实施例中，第一波束可以不对应特定的下行物理信道。比如，不同的下行物理信道都可以通过第一波束或者第二波束进行传输。
或者，与图5或图6所示的实施例类似的，在本发明实施例中，第一波束和第二波束也可以分别用于传输不同的下行物理信道。
步骤702，接入网设备向终端发送生成的至少两组波束信息。
可选的，接入网设备通过专用信令或广播信令发送该至少一组波束对应信息。
步骤703，终端接收发送端设备发送的至少两组波束信息。
相应的，终端通过专用信令或广播信令接收该至少一组波束对应信息。
步骤704，终端测量至少两组波束对应信息各自的第一波束的信号质量。
比如，以接入网设备发送的波束如图3所示为例，接入网设备发送波束1至波束9这9个第二波束，终端需要通过第二波束接收接入网设备发送的信令或数据时，需要从波束1至波束9中选择出信号质量最好的第二波束。通过本发明实施例所示的方案，终端接收到接入网设备发送的波束对应信息后，在选择接收的第二波束时，可以先测量与9个第二波束相对应的3个第一波束的信号质量，即对图3中的波束10、波束11和波束12的信号质量进行测量。
步骤705，终端测量至少两组波束对应信息各自的第一波束中，信号质量最好的第一波束对应的至少一个第二波束的信号质量。
终端对图3中的波束10、波束11和波束12的信号质量进行测量后，确定其中信号质量最好的第一波束，比如，假设确定出的信号质量最好的第一波束为波束11，则进一步的，终端对波束11对应3个第二波束(即波束4至波束6)进行信号质量的测量。
步骤706，终端将信号质量最好的第一波束对应的至少一个第二波束中，信号质量最好的第二波束选择为接收的波束。
具体的，终端可以将上述信号质量最好的第一波束对应的至少一个第二波束中，信号质量最好的第二波束选择为用来接收接入网设备发送的数据或信令的波束。
比如，终端对与信号质量最好的第一波束相对应的第二波束(即图3中的波束4至波束6)的信号质量进行测量后，可以选择接收波束4至波束6中信号质量最好的波束，并通过选择出的波束接收接入网设备发送的数据或信令。
具体例如，以波束对应信息中包含第一波束的参考信号与对应的各个第二波束的参考信号之间的对应关系为例，终端可以根据波束10、波束11和波束12的参考信号，测量波束10、波束11和波束12的信号质量，在确定出这三者中的波束11的信号质量最好之后，查询获得波束11的参考信号与波束4至波束6的参考信号之间的对应关系，并根据波束4至波束6的参考信号，测量波束4至波束6的信号质量，从中选择出信号质量最好的第二波束。
在本发明实施例的上述过程中，终端从图3所示的9个第二波束中选择出一个第二波束时，只需要先对3个第一波束进行测量，再对信号质量最好的第一波束对应的3个第二波束进行测量，前后经过6次测量即可以确定出接收的第二波束，不需要对9个第二波束分别进行一次测量。
综上所述，本发明实施例提供的波束选择方法，接入网设备向终端通知其发送的第一波束与第二波束之间的对应关系，终端从接入网设备发送的各个第二波束中选择一个第二波束进行接收时，只需要先对接入网设备发送的各个第一波束进行测量，再对其中信号质量最好的第一波束所对应的第二波束进行测量，即可以确定出接收的第二波束，不需要对接入网设备发送的所有第二波束分别进行测量，从而减少了通过第二波束接收数据或信令的过程中，对波束的信号质量进行测量的次数。
上述图5至图7所示的方案均以发送端设备为接入网设备，接收端设备为终端为例进行说明。本发明提供的波束选择方法，同样适用于接入网设备对终端发送的波束进行选择的情形。
请参考图8，其示出了本发明一个实施例提供的波束选择方法的方法流程图。本实施例以该波束选择方法应用于图1所示的移动通信系统中，发送端设备为终端，接收端设备为接入网设备，且终端通过第二波束发送上行数据信道，通过第一波束发送上行控制信道来举例说明。该方法包括：

相应的，接入网设备通过专用信令接收终端发送的该至少一组波束对应信息。
步骤804，接入网设备通过第二波束接收上行数据信道时，将第二波束对应的第一波束选择为用于接收上行控制信道的波束。
比如，以终端发送的波束如图2所示为例，终端通过第二波束(波束1至波束4)传输上行数据信道，并通过第一波束(波束5和波束6)传输上行控制信道，当接入网设备正在通过波束1(即上述第一第二波束)接收上行数据信道时，此时，若接入网设备需要接收上行控制信道，则不需要对波束5和波束6分别进行测量，直接根据接收到的波束对应信息，快速选择与波束1相对应的第一波束(波束5)，并通过波束5接收上行控制信道。

在基于图8的可选实施例中，终端也可以通过接入网设备发送的第一波束与第二波束之间的对应关系，选择用于接收下行数据信道的第二波束，此时，上述步骤804可以替换实现为步骤804a和步骤804b，如图9所示：
步骤804a，接入网设备通过第一波束接收上行控制信道时，根据至少一组波束对应信息，测量第一波束对应的至少一个第二波束的信号质量。
比如，以终端发送的波束如图2所示为例，终端通过第二波束(波束1至波束4)传输上行数据信道，并通过第一波束(波束5和波束6)传输上行控制信道，当接入网设备正在通过波束5接收上行控制信道时，此时，若需要接收上行数据信道，则可以根据接收到的波束对应信息，选择对与波束5相对应的第二波束(波束1和波束2)进行信号质量的测量，不需要对波束3和波束4分别进行测量。
步骤804b，接入网设备将第一波束对应的至少一个第二波束中，信号质量最好的第二波束选择为用于接收上行数据信道的波束。
比如，以图2所示为例，接入网设备对波束1和波束2分别进行信号质量的测量后，选择通过波束1和波束2中信号质量最好的波束接收上行数据信道。
综上所述，本发明实施例提供的波束选择方法，终端通过第二波束传输下行数据信道，通过第一波束传输下行控制信道，并向接入网设备通知其发送的第一波束与第二波束之间的对应关系，接入网设备在通过第一波束接收终端传输的上行控制信道时，若需要接收上行数据信道，则可以根据第一波束与第二波束之间的对应关系，仅对第一波束对应的第二波束进行测量，不需要对终端发送的所有第二波束分别进行测量，从而减少了接收上行数据信道的过程中，对波束的信号质量进行测量的次数。
请参考图10，其示出了本发明一个实施例提供的波束选择方法的方法流程图。本实施例以该波束选择方法应用于图1所示的移动通信系统中，发送端设备为终端，接收端设备为接入网设备来举例说明。该方法包括：
步骤1001，终端生成至少两组波束对应信息，每组波束对应信息中包含一个第一波束与至少一个第二波束之间的对应关系。
在本发明实施例中，第一波束可以不对应特定的上行物理信道。比如，不同的上行物理信道都可以通过第一波束或者第二波束进行传输。

步骤1006，接入网设备将该信号质量最好的第一波束对应的至少一个第二波束中，信号质量最好的第二波束选择为接收的波束。
具体的，接入网设备可以将上述信号质量最好的第一波束对应的至少一个第二波束中，信号质量最好的第二波束选择为用来接收终端发送的数据或信令的波束。
比如，接入网设备对图3中的波束4至波束6的信号质量进行测量后，选择波束4至波束6中信号质量最好的波束作为用于接收数据或信令的波束。
在本发明实施例的上述过程中，接入网设备从图3所示的9个第二波束中选择出一个第二波束时，只需要先对3个第一波束进行测量，再对信号质量最好的第一波束对应的3个第二波束进行测量，前后经过6次测量即可以确定出接收的第二波束，不需要对9个第二波束分别进行一次测量。
综上所述，本发明实施例提供的波束选择方法，终端向接入网设备通知其发送的第一波束与第二波束之间的对应关系，接入网设备从终端发送的各个第二波束中选择一个第二波束进行接收时，只需要先对终端发送的各个第一波束进行测量，再对其中信号质量最好的第一波束所对应的第二波束进行测量，即可以确定出接收的第二波束，不需要对终端发送的所有第二波束分别进行测量，从而减少了通过第二波束接收数据或信令的过程中，对波束的信号质量进行测量的次数。
需要说明的是，上述图5至图10所示的各个实施例中由接入网设备执行的步骤可以单独实现成为接入网设备侧的波束选择方法，上述图5至图10所示的各个实施例中由终端执行的步骤可以单独实现成为终端侧的波束选择方法。
请参考图11，其示出了本发明一个实施例提供的波束选择方法的方法流程 图。本实施例以该波束选择方法应用于图1所示的移动通信系统中来举例说明。该方法包括：
步骤1101，发送端设备生成至少一组波束对应信息，每组波束对应信息中包含第一信号所在波束与第二信号所在波束之间的对应关系。
可选的，第一信号所在波束与第二信号所在波束是同一波束。
在本发明实施例中，发送端设备通过波束成形技术进行多波束发送时，可以在不同的波束上发送属于同一类型的不同信号，并且，同一个波束上可以发送不同类型的多个信号。发送端设备可以根据其发送的各个波束上的第一信号和第二信号，生成一组波束对应信息。
比如，以图2为例，其中波束1至波束4各自发送第一信号和第二信号，其中，波束1中发送的第一信号为信号11，且波束1中发送的第二信号为21，波束2中发送的第一信号为信号12，且波束2中发送的第二信号为22，波束3中发送的第一信号为信号13，且波束3中发送的第二信号为23，波束4中发送的第一信号为信号14，且波束4中发送的第二信号为24。则上述波束1对应的一组波束对应信息中包含信号11所在波束和信号21所在波束之间的对应关系，相应的，波束2对应的一组波束对应信息中包含信号12所在波束和信号22所在波束之间的对应关系，波束3对应的一组波束对应信息中包含信号13所在波束和信号23所在波束之间的对应关系，波束4对应的一组波束对应信息中包含信号14所在波束和信号24所在波束之间的对应关系。
其中，上述第一信号所在波束和第二信号所在波束之间的关系，可以直接是第一信号的信号内容与第二信号的信号内容之间的对应关系，也可以是第一信号的标识与第二信号的标识之间的对应关系，或者，也可以是第一信号的信号内容与第二信号的标识之间的对应关系，或者，也可以是第一信号的标识与第二信号的信号内容之间的对应关系等等。
步骤1102，发送端设备向接收端设备发送至少一组波束对应信息。
在本发明实施例中，发送端设备可以通过准同址(Quasi Co-Located，QCL)参数发送波束对应信息，即发送端设备向接收端设备发送指示至少一组波束对应信息的准同址参数。
或者，
在本发明实施例中，发送端设备也可以通过专用信令发送波束对应信息，即发送端设备向接收端设备发送包含该至少一组波束对应信息的专用信令，比 如无线资源控制(Radio Resource Control，RRC)信令。
步骤1103，接收端设备接收该至少一组波束对应信息。
相应的，当发送端设备可以通过准同址参数发送波束对应信息时，接收端设备接收发送端设备发送的准同址参数，获取准同址参数所指示的至少一组波束对应信息。
或者，
当发送端设备通过专用信令发送波束对应信息时，接收端设备接收发送端设备通过专用信令发送的至少一组波束对应信息。
步骤1104，接收端设备根据至少一组波束对应信息，从发送端设备发送的各个波束中选择接收的波束。
具体的，在本发明实施例中，接收端设备可以获取通过对各个波束中的第一信号进行测量获得的，各个波束各自的信号质量；接收端设备根据至少一组波束对应信息，查询各个波束中信号质量最好的波束中的第一信号所对应的第二信号；接收端设备将信号质量最好的波束，选择为用于接收信号质量最好的波束中的第一信号所对应的第二信号的波束。
通过本发明实施例所示的方法，接收端设备可以对发送端设备发送的各个波束中的第一信号进行测量，以获得各个波束各自的信号质量，以便后续在接收第二信号时，根据接收到的波束对应信息，直接查询确定信号最强的波束中携带的第二信号是哪一个信号，从而直接通过该信号最强的波束接收确定的第二信号，不需要再针对第二信号进行波束扫描。
综上所述，本发明实施例所示的方法，接收端设备在对第一信号进行测量之后，后续需要接收第二信号时，不需要再对第二信号进行测量，直接根据波束对应信息即可以选择出用于接收的波束，从而减少对波束中各种信号分别进行测量的步骤或次数，从而减少波束测量所耗费的时间，加速接收端设备的波束测量和选择的过程，简化系统复杂度，降低数据接收的时延。
需要说明的是，上述图11所示实施例中由接收端设备执行的步骤可以单独实现成为接收端设备侧的波束选择方法，上述各个实施例中由发送端设备执行的步骤可以单独实现成为发送端设备侧的波束选择方法。
5G系统可以通过不同的beam来覆盖整个小区，即每个beam覆盖一个较 小的范围，通过时间上的扫描(sweeping)来实现多个beam覆盖整个小区的效果。不同beam上传输不同的同步信号块(SS block)，终端可以通过不同的SS block来分辨出不同的beam。
终端在开机搜索小区的过程中就开始做波束扫描(beam sweeping)，通过测量不同的SS block以获得最佳的下行beam(即信号质量最好的波束)。而终端在空闲态(idle mode)下，监听寻呼信道/信号(paging channel/signal)时也需要选择信号质量最好的波束；当终端进入连接态后，终端在做移动性管理时，可能还需要测量CSI-RS，不同的CSI-RS配置与不同的波束对应；类似的，在其它时刻，终端可能还需要测量下行DMRS对应的波束。由于终端在做小区选择时已经测量过SS block,因此，通过上述图4所示的方案，系统可以指示SS block与其它信号/信道的波束之间的对应关系，后续在选择波束对其它信号/信道进行测量时，能大大简化波束选择的过程。
请参考图12，其示出了本发明一个实施例提供的波束选择方法的方法流程图。本实施例以该波束选择方法应用于图1所示的移动通信系统中，发送端设备为接入网设备，接收端设备为终端来举例说明。该方法包括：
步骤1201，接入网设备生成至少一组波束对应信息，每组波束对应信息中包含SS block(第一信号)所在波束与第二信号所在波束之间的对应关系。
可选的，第一信号所在波束与第二信号所在波束是同一波束。
其中，该第一信号为参考信号块SS block；第二信号包括寻呼信号、信道状态信息参考信号CSI-RS以及解调参考信号DMRS中的至少一种。
在本发明实施例中，当第二信号包括寻呼信号时，上述对应关系可以包括：SS block与寻呼信道/信号之间的对应关系。
当第二信号包括信道状态信息参考信号CSI-RS时，上述对应关系可以包括：SS block与CSI-RS资源之间的对应关系；和/或，SS block与CSI-RS端口之间的对应关系。
当第二信号包括解调参考信号DMRS时，上述对应关系包括：SS block与DMRS端口或端口集合之间的对应关系。
步骤1202，接入网设备向终端发送至少一组波束对应信息。
在本发明实施例中，接入网设备可以通过广播方式向终端发送系统信息块(System Information Block，SIB)，该SIB中携带的QCL参数指示上述至少一组波束对应信息。
或者，接入网设备也可以通过专用信令，比如RRC signaling，向终端发送上述至少一组波束对应信息。
步骤1203，终端接收该至少一组波束对应信息。
相应的，当接入网设备通过QCL参数发送波束对应信息时，中高端接收接入网设备通过广播发送的SIB中的QCL参数，并获取QCL参数所指示的至少一组波束对应信息。
或者，
当接入网设备通过RRC signaling发送波束对应信息时，终端接收接入网设备通过RRC signaling发送的至少一组波束对应信息。
步骤1204，终端根据至少一组波束对应信息，从接入网设备发送的各个波束中选择接收的波束。
在本发明实施例中，终端可以获取预先通过对各个波束中的SSblock进行测量获得的，各个波束各自的信号质量，根据至少一组波束对应信息，查询各个波束中信号质量最好的波束中的SS block所对应的第二信号，并将信号质量最好的波束，选择为用于接收信号质量最好的波束中的SS block所对应的第二信号的波束。
终端接收到接入网设备生成并发送的波束对应信息，比如QCL参数后，利用SS bock与其它信号/信道的对应关系加快波束选择的过程。具体比如，接入网设备在一个20ms周期内广播2个SS block，接入网设备也采用2个beam去广播寻呼(paging)消息。同时，接入网设备通过SIB指示这2个SS block和广播paging消息的两个beam之间的对应关系，比如，指示SS block1和paging message1的QCL参数表示SS block1和paging message1在同一个beam上发送，而指示SS block2和paging message2的QCL参数表示SS block2和paging message2在另一个beam上发送。终端在做小区搜索的时候发现SS block1对应的波束方向上的信号质量最强，则终端就可以依据上述信号对应关系，在SS block1对应的波束方向上直接监听paging message1。不需要对paging message1和paging message 2先做波束扫描,再根据波束扫描的结果决定监听paging message1或paging message2，从而加快终端选择波束的过程。
综上所述，本发明实施例所示的方法，接收端设备可以对发送端设备发送的各个波束中的第一信号进行测量，以获得各个波束各自的信号质量，以便后续在接收第二信号时，根据接收到的信号对应关系，直接查询确定信号最强的 波束中携带的第二信号是哪一个信号，从而直接通过该信号最强的波束接收确定的第二信号，不需要再针对第二信号进行波束扫描，从而减少对波束中各种信号分别进行测量的步骤或次数，从而减少波束测量所耗费的时间，加速接收端设备的波束测量和选择的过程，简化系统复杂度，降低数据接收的时延。
