为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。其中，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
下面将结合附图对本申请作进一步地详细描述。方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。其中，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
需要说明的的是，本申请的通信方法可由装置执行。其中，该装置可以包括网络侧的装置和/或终端侧的装置。在网络侧，该装置可以是基站或基站内的芯片，即可以由基站或基站内的芯片执行本申请的通信方法；在终端侧，该装置可以是终端或终端内的芯片，即可以由终端或终端内的芯片执行本申请的通信方法。
为方便说明，本申请，以装置为基站或终端为例，对通信方法进行说明，对于装置为基站内的芯片或终端内的芯片的实现方法，可参考基站或终端的通信方法的具体说明，不再重复介绍。
如图1所示，为本申请的一种可能的网络架构示意图。包括终端、第一基站和第二基站。
其中，第二基站为终端的服务小区的基站，或者理解为第二基站的某个小区为终端的服务小区。第一基站为该终端的服务小区的邻区的基站，或者理解为，第一基站的某个或某些小区为该终端的服务小区的邻区。且该第一基站与第二基站是不同的基站。
终端可以从第二基站接收控制命令和/或数据。当然，终端也可以从第一基站接收控制命令和/或数据，比如可以从第一基站接收广播信息等。
第一基站与第二基站之间可以通过有线连接进行通信，或者还可以通过空口的方式进行通信。
本申请中，终端是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
基站，是一种为终端提供无线通信功能的设备，包括但不限于：5G中的下一代基站(g nodeB，gNB)、演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB， 或home node B，HNB)、基带单元(BaseBand Unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。
本申请中，第一基站是具有基于网络的CRS带宽缩减能力的基站，其中，基于网络的CRS带宽缩减能力是指，第一基站在发送CRS时，可以在部分带宽(即缩减后的带宽)上发送CRS。从而可以减少带宽资源的占用，有利于节约资源，进一步地，还可以减少对邻区的干扰。例如，第一基站占用的全部带宽为20RB，作为示例，第一基站若采用基于网络的CRS缩减技术，例如可以在中间的6RB上发送CRS，这里的6RB可以称为缩减带宽。
作为一种示例，本申请中的第二基站也可以具有基于网络的CRS带宽缩减能力。作为又一种示例，本申请中的第二基站也可以不具有基于网络的CRS带宽缩减能力。
比如，在一种应用场景中，第一基站为新一代的基站，其具有基于网络的CRS带宽缩减能力。而第二基站是上一代的基站，第二基站不具有基于网络的CRS带宽缩减能力。
再比如，在又一种应用场景中，第一基站和第二基站均为新一代的基站，因而均具有基于网络的CRS带宽缩减能力。
本申请将基于图1所示的网络架构，介绍本申请的通信方法。
可以理解的是，上述功能既可以是硬件设备中的网络元件，也可以是在专用硬件上运行软件功能，或者是平台(例如，云平台)上实例化的虚拟化功能。
如图2所述，为本申请提供的一种通信方法，包括以下步骤：
步骤201，第一基站向第二基站发送第一信息。相应地，第二基站接收该第一信息。
该第一信息包括第一基站的基于网络的CRS带宽缩减状态信息。
需要说明的是，当第一基站具备基于网络的CRS带宽缩减能力时，第一基站才会向第二基站发送第一基站的基于网络的CRS带宽缩减状态信息。
比如，若第一基站当前的基于网络的CRS带宽缩减状态为：发送CRS的带宽缩减为X。作为一种实现方式，该状态信息可以表示为X。作为又一种实现方式，可以使用1比特指示第一基站当前处于CRS带宽缩减状态，如使用“1”表示第一基站当前处于CRS带宽缩减状态，即状态信息为“1”，或者使用“0”表示第一基站当前处于CRS带宽缩减状态，即状态信息为“0”。
再比如，若第一基站当前的基于网络的CRS带宽缩减状态为：发送CRS的带宽未缩减。即第一基站使用全部带宽发送CRS。作为一种实现方式，该状态信息可以表示为Y(这里的Y指的是第一基站占用的全部带宽)。作为又一种实现方式，可以使用1比特指示第一基站当前处于CRS带宽缩减状态，如使用“1”表示第一基站当前处于CRS带宽未缩减状态，即状态信息为“1”，或者使用“0”表示第一基站当前处于CRS带宽未缩减状态，即状态信息为“0”。
通过上述方法，第一基站可以将自身的基于网络的CRS带宽缩减状态信息发送至第二基站，从而第二基站可获知第一基站的基于网络的CRS带宽缩减状态信息。相应地，若第二基站也具有基于网络的CRS带宽缩减能力，则第二基站也可以将自身的基于网络的CRS带宽缩减状态信息发送至第一基站。从而可实现第一基站与第二基站之间的缩减信息(如第一基站的基于网络的CRS带宽缩减状态信息，或第二基站的基于 网络的CRS带宽缩减状态信息)的同步。
作为一种实现方式，触发第一基站向第二基站发送上述第一信息的条件，包括但不限于以下至少一种：
条件一，第一基站的CRS配置发生变化。
比如，第一基站的基于网络的CRS带宽缩减状态由发送CRS的带宽缩减更新为发送CRS的带宽未缩减，则确定CRS配置发生变化。
再比如，第一基站的基于网络的CRS带宽缩减状态由发送CRS的带宽未缩减更新为发送CRS的带宽缩减，则确定CRS配置发生变化。
当第一基站确定自身的CRS配置发生变化，则生成基于网络的CRS带宽缩减状态信息，并将基于网络的CRS带宽缩减状态信息发送给第二基站。
条件二，第一基站接收到来自第二基站的第一请求信息，该第一请求信息用于指示第一基站向第二基站发送第一基站的基于网络的CRS带宽缩减状态信息。
该方式，第二基站主动向第一基站请求获取第一基站的基于网络的CRS带宽缩减状态信息，因此，当第一基站接收到上述第一请求信息时，则生成基于网络的CRS带宽缩减状态信息，并发送给第二基站。
条件三，第一基站的发送周期到达。
即第一基站是周期性地向第二基站发送第一基站的基于网络的CRS带宽缩减状态信息。因此，当发送周期到达时，第一基站生成基于网络的CRS带宽缩减状态信息，并发送给第二基站。
作为一种实现方式，在上述步骤201之后，还可以包括以下步骤202。
步骤202，第二基站向第一基站发送第三信息。相应地，第一基站接收该第三信息。
该第三信息用于通知接收到上述第一信息。即该第三信息可以理解为一个针对接收上述第一信息的响应信息，用于通知第一基站：第二基站已经接收到上述第一信息。
作为一种实现方式，在上述步骤201之后，还可以包括以下步骤203。
步骤203，第一基站向第二基站发送第二信息。相应地，第二基站接收该第二信息。
该第二信息包括第一基站的基于网络的CRS带宽缩减能力信息。
作为一种实现方式，可以使用1比特来表示第一基站的基于网络的CRS带宽缩减能力。比如，若第一基站具有基于网络的CRS带宽缩减能力，则第一基站的基于网络的CRS带宽缩减能力信息可以表示为“1”，若第一基站不具有基于网络的CRS带宽缩减能力，则第一基站的基于网络的CRS带宽缩减能力信息可以表示为“0”。
或者，若第一基站具有基于网络的CRS带宽缩减能力，则第一基站的基于网络的CRS带宽缩减能力信息表示为“0”，若第一基站不具有基于网络的CRS带宽缩减能力，则第一基站的基于网络的CRS带宽缩减能力信息表示为“1”。
本申请中，第一基站具有基于网络的CRS带宽缩减能力。
作为一种实现方式，触发第一基站向第二基站发送上述第二信息的条件，例如可以是：第一基站接收来自所述第二基站的第二请求信息，所述第二请求信息用于指示第一基站向第二基站发送第一基站的基于网络的CRS带宽缩减能力信息。
因此，当第一基站接收到来自第二基站的上述第二请求信息时，则第一基站向第 二基站发送上述第二信息，即发送第一基站的基于网络的CRS带宽缩减能力信息。
作为一种实现方式，在上述步骤203之后，还可以包括以下步骤204。
步骤204，第二基站向第一基站发送第四信息。相应地，第一基站接收该第四信息。
该第四信息用于通知接收到上述第二信息。即该第四信息可以理解为一个针对接收上述第二信息的响应信息，用于通知第一基站：第二基站已经接收到上述第二信息。
需要说明的是，作为一种实现方式，上述步骤201和步骤203可以合并为一个步骤，例如第一基站通过同一个消息向第二基站发送第一信息和第二信息。相应地，上述步骤202和步骤204也可以合并为一个步骤，即第二基站可以通过同一个消息向第一基站发送第三信息和第四信息。
作为一种实现方式，在上述步骤201之后，还可以包括以下步骤205、步骤206和步骤209，或者包括步骤207、步骤208和步骤209。
步骤205，第二基站向终端发送第一信息。相应地，终端接收该第一信息。
终端在接收到该第一信息之后，可以根据第一信息确定测量带宽值。
步骤206，终端确定测量带宽值。
作为一种实现方式，当第一基站的基于网络的CRS带宽缩减状态信息指示为缩减带宽值时，则终端将缩减带宽值确定为测量带宽值。例如，第二基站发送给终端的第一信息中包括的第一基站的基于网络的CRS带宽缩减状态信息为6RB，则终端可以将测量带宽值确定为6RB。
作为又一种实现方式，当第一基站的基于网络的CRS带宽缩减状态信息指示为缩减状态时，则终端从该缩减状态对应的多个缩减带宽值中确定一个作为测量带宽值。例如，预先约定“1”表示第一基站的基于网络的CRS带宽缩减状态为缩减状态，“0”表示第一基站的基于网络的CRS带宽缩减状态为未缩减状态，且预先设定缩减状态对应的缩减带宽值为{6RB，5RB，4RB}，则当第一基站的基于网络的CRS带宽缩减状态信息为“1”时，则终端确定第一基站的基于网络的CRS带宽缩减状态信息为缩减状态，则从{6RB，5RB，4RB}中确定一个作为测量带宽值，例如随机选择，或者是按使用次数最多的选择等。比如选择的是5RB，则终端确定测量带宽值为5RB。
需要说明的是，本申请上述步骤206中，作为一种实现方式，终端可以针对每个邻区分别确定一个测量带宽值，然后根据该测量带宽值对该邻区进行测量；同样地，终端可以针对该终端的服务小区确定一个测量带宽值，然后根据该测量带宽值对该服务小区进行测量。作为又一种实现方式，终端还可以针对终端的服务小区及该服务小区的所有邻区确定同一个测量带宽值，然后根据该同一个测量带宽值对终端的服务小区及该服务小区的所有邻区进行测量。在具体实现中，终端可以只对服务小区进行测量，也可以只对服务小区的邻区进行测量，还可以是既对服务小区进行测量也对服务小区的邻区进行测量。
作为又一种实现方式，若第二基站也具有基于网络的CRS带宽缩减能力，则第二基站还可以将第二基站的基于网络的CRS带宽缩减状态信息发送给终端，然后终端根据第一信息和第二基站的基于网络的CRS带宽缩减状态信息确定测量带宽值。例如，当第一基站的基于网络的CRS带宽缩减状态信息指示为第一缩减带宽值，第二基站的基于网络的CRS带宽缩减状态信息指示为第二缩减带宽值时，则终端可以将第一缩减 带宽值和第二缩减带宽值中的较大值或较小值确定为测量带宽值。
步骤207，第二基站确定测量带宽值。
该步骤207中第二基站根据第一信息确定测量带宽值的方法，可以参考上述步骤206中终端确定测量带宽值的方法，这里不再赘述。
步骤208，第二基站向终端发送测量带宽值。相应地，终端接收该测量带宽值。
若采用上述步骤206和步骤207的方法，则是由第二基站将第一信息发送给终端，由终端确定测量带宽值。
若采用上述步骤208和步骤209的方法，则是由第二基站确定测量带宽值，然后将测量带宽值发送给终端。
步骤209，终端根据测量带宽值，测量终端所在的服务小区或该服务小区的邻区的信号强度或信号质量中的至少一项。
当该测量带宽值为第一基站缩减状态下的带宽值时，由于该带宽是第一基站占用的全部带宽中的部分带宽，因而终端在测量时可以节约测量的开销。
通过上述方法，一方面可以实现第一基站将第一基站的基于网络的CRS带宽缩减状态信息发送给第二基站，进一步地，第一基站还可以将第一基站的基于网络的小区参考信号CRS带宽缩减能力发送给第二基站，实现了第一基站与第二基站之间的缩减信息(如第一基站的基于网络的CRS带宽缩减状态信息，第一基站的基于网络的CRS带宽缩减能力信息)的同步。另一方面，还实现了第一基站与终端之间同步带宽缩减状态信息的同步，进而可实现由终端基于带宽缩减状态信息重新确定测量带宽值，并根据重新确定的测量带宽值进行小区测量，可以减少终端测量时的开销。
如图3所示，为本申请提供的又一种通信方法，该方法可以是结合上述图2所示的通信方法共同实施，也可以是单独实施，对此本申请不做限定。图3所示的通信方法包括以下步骤：
步骤301，第二基站向终端发送第一信息。相应地，终端接收该第一信息。
该第一信息指的是图2所示的实施例中的第一信息。
作为一种可替代的实现方法，该步骤301还可以替换为：第一基站向终端广播发送第一信息。该方法，第一基站可以通过广播的方式将第一信息发送个终端。
可选地，若第二基站具有基于网络的CRS带宽缩减能力，则还可以包括以下步骤302。
步骤302，第二基站向终端发送第二基站的基于网络的CRS带宽缩减状态信息。相应地，终端接收第二基站的基于网络的CRS带宽缩减状态信息。
步骤303，终端确定测量带宽值。
该步骤303与上述步骤206的实现方法相同，可参考前述描述。
步骤304，终端根据测量带宽值，测量终端所在的服务小区或该服务小区的邻区的信号强度或信号质量中的至少一项。
当该测量带宽值为第一基站缩减状态下的带宽值时，由于该带宽是第一基站占用的全部带宽中的部分带宽，因而终端在测量时可以节约测量的开销。
通过上述通信方法，终端可获取到第一基站的基于网络的小区参考信号CRS带宽缩减状态信息发送给终端，实现了第一基站与终端之间同步带宽缩减状态信息。进而， 可实现由终端基于带宽缩减状态信息重新确定测量带宽值，并根据重新确定的测量带宽值进行小区测量，可以减少终端测量时的开销。
