背景技术
为了增强传统第五代(5th Generation，5G)***网络架构中上行能力，需要引入新频段。然而无线电频谱资源拥挤，引入的5G新频段会与雷达/无线保真(wireless fidelity，WIFI)***/卫星等互相干扰，导致各***间无法共存。目前虽然可以采用超级上行解决方案避免了基站对雷达的干扰，使得雷达与5G***的共存成为可能，但是雷达对基站、辅助上行(supplementary uplink，SUL)终端设备对雷达的干扰仍然存在。
参见图1，图1是雷达与5G***网络***间的干扰的示意图。如图1所示，雷达对5G***的干扰包括由于雷达发射功率及天线主瓣增益极大，在严重情况例如基站位于雷达主瓣方向且两者相隔距离较近时，可能造成电路烧毁；另一方面，当雷达干扰不足以烧毁电路时，造成5G终端设备/基站的信道环境变差，误码率增加。另外，5G***对雷达的干扰包括5G终端设备/基站的干扰使得雷达灵敏度劣化，存在法律问题。

结合第一方面，在第一方面的某些实现方式中，调整第一网络设备的天线的下倾角，使得第一网络设备受到雷达信号的干扰小于第三阈值。
上述技术方案中，通过调整网络设备的下倾角，使得5G通信与雷达在上行频段的时域频域上发生碰撞时，两者仍能共存，从而提高了无线频谱的利用率。

(1)第一网络设备基于雷达信号的特征(例如：雷达的发射周期)在时域决策单元中判断当前是否处于雷达信号的发射周期，如果是，跳转步骤(2)，如果否，跳转步骤(3)；
(2)如果当前处于雷达信号的发射周期，可以使用以下方法中的一种或多种以减小雷达信号的干扰：
①第一网络设备停止SUL新频段对应的小区的用户调度；
②第一网络设备指示一个或多个第一终端设备在发射周期上的上行发射功率不超过第一阈值(例如：第一阈值可以为第一终端设备的上行发射功率的保守值(-20dB))，其中，第一终端设备是通过SUL新频段与第一网络设备进行通信的终端设备；
可选的，第一阈值可以由网络设备确定，也可以由终端设备根据实际情况确定，本申请不做限定。例如，第一网络设备可以向一个或者多个第一终端设备发送指示信息，该终端设备根据该指示信息，调整在发射周期上的上行发射功率，使得其不超过第一阈值。
③第一网络设备调整循环前缀(cyclic prefix，CP)的长度和/或位置，使得雷达信号落在该CP内。

参见图4，图4是本申请提供的频域保护措施的示意性流程图。
(1)可选的，第一网络设备基于雷达信号的特征(例如：雷达信号的频域资源位置和频域资源上受到的干扰的能量)在频域决策单元中判断雷达信号在SUL新频段上的能量(或者雷达干扰电平)是否超过预设的门限值，如果是，跳转步骤(2)，如果否，跳 转步骤(3)；
(2)可以使用以下方法中的一种或多种以减小雷达信号的干扰：
①去激活SUL新频段中雷达信号频域资源对应的频点小区的中射频器件，或将第一网络设备直接下电，其中，去激活可以理解为不工作、断电或者进入休眠状态等状态；②调整SUL新频段上的小区***带宽或部分带宽(bandwidth part，BWP)；
可选的，调整完SUL新频段上的小区***带宽或部分带宽后，SUL新频段上的小区***带宽或部分带宽可以避开雷达信号所在的频域资源。
③指示一个或多个第一终端设备在雷达信号的频域资源上的上行发射功率不超过第二阈值。
可选的，第二阈值可以由网络设备确定，也可以由终端设备根据实际情况确定，本申请不做限定。
关于第一网络设备的指示方式可以参考上述时域保护措施的内容。
(3)可以使用以下方法中的一种或多种以减小雷达信号的干扰：
①第一网络设备将SUL新频段中受干扰的物理资源块(physical resource block，PRB)(即雷达信号频域资源)优先分配给SUL新频段对应的小区的近点用户；
②第一网络设备对雷达信号进行频域避让，频域避让包括不调度SUL新频段中受干扰的PRB。
可选的，在上述图4的方法中，可以不存在步骤(1)，即第一网络设备基于雷达信号的特征在频域决策单元中判断雷达信号在SUL新频段上的能量是否超过预设的门限值，直接执行步骤(2)和(3)中的一个或者多个频域保护措施。
参见图5，图5是本申请提供空域保护措施的示意性流程图。
在图5的方法中，第一网络设备可以调整所述第一网络设备的天线的下倾角，使得所述第一网络设备受到所述雷达信号的干扰小于第三阈值。例如，当所述雷达信号的干扰小于第三阈值时，可以认为第一网络设备检测不到雷达干扰(即雷达干扰不存在)。下面结合具体的步骤进行说明。
(1)第一网络设备基于雷达信号的特征在空域决策单元中判断第一网络设备的天线当前的下倾角对应的雷达信号的干扰是否存在，如果存在，跳转步骤(2)，如果不存在，则正常进行终端设备的小区的用户调度等任务。
(2)第一网络设备调整天线下倾角，其中，下倾角包括电子下倾角和机械下倾角。以电子下倾角为例，第一网络设备可以在后台对应不断增大电子下倾角(例如每次下调1度，调整度数不限制)，以降低雷达干扰方向的网络设备天线接收增益和发射增益。
(3)第一网络设备调整下倾角之后，重新计算雷达信号对第一网络设备的干扰情况，此时，如果检测不到雷达干扰，第一网络设备停止调整下倾角；如果仍能检测到雷达干扰，继续调整下倾角。应理解，如果第一网络设备已遍历所有下倾角仍存在雷达信号的干扰，则在第一网络设备遍历的所有下倾角中确定雷达干扰最小的下倾角，将雷达干扰最小时对应的下倾角作为第一网络设备最终的下倾角，从而降低雷达信号的干扰。
可选的，步骤(1)中也可以确定第一网络设备的天线对应的雷达干扰是否小于第三阈值，如果不小于第三阈值，则跳转步骤(2)调整第一网络设备的下倾角，如果小于第三阈值，则正常进行终端设备的小区的用户调度等任务，这里不再赘述。
可选的，第一网络设备可以采用上述时域、频域、空域的保护措施中的一种或多种措施，本申请不做限定。S203，第一网络设备执行保护措施以减少雷达信号和上行频段之间的干扰。
S204，第一网络设备通过SUL新频段与一个或者多个第一终端设备进行通信。
本申请所保护的技术方案，与现有技术相比，第一网络设备在执行上述保护措施时，5G通信与雷达在SUL频段的时域频域上发生碰撞时，两者仍能共存，也就是说，第一网络设备仍然可以在SUL新频段上与终端进行通信，从而提高了无线频谱的利用率。
可选的，S205，第一网络设备在采用上述保护措施后，重新评估雷达信号的干扰是否仍然存在，当干扰仍然存在时，重复使用上述保护措施减少所述雷达信号和SUL新频段之间的干扰。
上述技术方案中，通过时域频域和空域的减少雷达和上行频段之间的干扰的保护措施，解决了5G***与雷达在同一频段的共存问题。此外，本申请的技术方案均在网络设备及终端设备侧进行，不需要具备控制雷达的权利。同时雷达发射功率极大，网络设备或终端设备在检测出雷达干扰信号存在时，SUL终端设备对雷达无干扰，因此使用本发明无违法违规风险。
