技术领域
本发明涉及通信领域，具体涉及一种波束检测和调整方法及装置、天线模块选择方法及装置、以及计算机可读存储介质。
背景技术
5G毫米波移动通信系统使用阵列天线与波束赋形技术，5G终端毫米波芯片使用封装天线技术，具有显著的方向选择性。快速准确的收发端波束对齐和跟踪是实现毫米波通信的一项重要技术。由于毫米波频段信号衰减快、散射绕射特性差，容易被遮挡，因此通过细窄波束可将信号能量集中，通过波束管理能够动态跟踪调整波束方向变化，从而较好地支持毫米波频段信道的快变特性。
现有的一些方案中，终端在网络中通过无线资源控制(Radio Resource Control，RRC)协议进行各种波束扫描并结合相关对准策略完成波束管理。然而，这种方法占用较多网络资源，终端侧需要较多的基带处理并相应地产生较大的功耗。
现有的其他方案中，在终端中增设专用于射频环境检测的天线或感应装置，以及相应的电调谐元件、信号处理与控制电路，但这些硬件结构难以与终端主通信系统芯片组集成，显著地增加了终端的器件、体积和成本。

与现有技术相比，本发明实施例的技术方案具有以下有益效果。
本发明实施例提供的基于AiP结构的波束检测方法和装置中，通过AiP结构中的ULA阵列检测该ULA阵列对应的UPA阵列发射的信号，并对检测结果进行存储。所述方法可以应用于AiP结构完成设计定型时，此时UPA阵列与ULA阵列之间形成了固定的物理通道，当UPA阵列发射特定的信号时，通过对应的ULA阵列可以检测到相对固定的信号。此时AiP结构周围不存在多余的遮挡，即处于较理想的环境中，检测到的结果即是AiP结构设计时的预设阈值。存储所述检测结果的意义在于：当AiP结构周围存在遮挡时，可以将检测到的信号的参数值与所述存储的预设阈值进行比较，基于比较结果可以判 断出实际发射的波束与设计中存在的偏离，进而据此去调整波束。

进一步地，存储所述最优波束配置的意义在于：当包括所述AiP结构的终端设备投入实际应用中时，其周围将存在更多的遮挡，可以将检测到的信号的参数值与所述存储的最优波束配置进行比较，基于比较结果可以选择基于所述AiP结构中性能最好的AiP进行信号收发。
进一步地，本发明实施例提供的天线模块选择方法和装置中，通过AiP中的ULA阵列检测对应的UPA阵列发射的信号，将终端设备中多个AiP检测到的信号的特征参数值与对应的预设特征参数值进行比较，基于比较结果选择波束性能最好的AiP用于终端设备的信号收发。因此，实现了终端对波束的本地检测和管理，并且无需增加额外硬件，节省了网络资源，减小了终端的成本和功耗。
进一步地，默认使用AiP中的UPA阵列进行信号收发，若检测到的UPA阵列发射的信号的波束性能都不理想，可以使用AiP中的ULA阵列进行信号收发。
进一步地，默认使用AiP中的UPA阵列进行信号收发，若检测到的UPA阵列发射的信号的波束性能都不理想，也可以使用RRC协 议进行波束扫描和管理。
进一步地，每个AiP在不同时刻受遮挡的程度不尽相同，利用本发明实施例提供的方法实时检测、比较，可以实现AiP之间的动态切换，以保证更优的通信质量。

具体实施方式
如背景技术所述，现有的波束管理方法包括终端在网络中基于RRC协议完成波束管理，但这种方法不仅占用较多网络资源，终端侧还会产生较大的功耗。现有的波束管理方法还包括在终端中增设专用于射频环境检测的天线或感应装置，以及相应的电调谐元件、信号处理与控制电路，但这种方法加大了硬件结构集成的难度，增加了终端的体积和成本。
发明人经研究发现，终端在实际应用中最为常见的遮挡来自于天 线射频模块安装附近的其它器件及外壳、手持及其它人体遮挡、终端附近其它对射频传播产生反射或折射的物体等等，这些因素与网络状态的相关性低。如果天线射频模块或终端直接感知附近的射频环境，天线射频模块可以本地检测并调整波束，终端可以选择波束最优配置，将提高波束调整效率、节约功耗。
本发明实施例提供了一种基于AiP结构的波束检测方法。通过AiP结构中的ULA阵列检测该ULA阵列对应的UPA阵列发射的信号，并对检测结果进行存储。所述方法可以应用于AiP结构完成设计定型时，此时UPA阵列与ULA阵列之间形成了固定的物理通道，当UPA阵列发射特定的信号时，通过对应的ULA阵列可以检测到相对固定的信号。此时AiP结构周围不存在多余的遮挡，即处于较理想的环境中，检测到的结果即是AiP结构设计时的预设阈值。存储所述检测结果的意义在于：当AiP结构周围存在遮挡时，可以将检测到的信号的参数值与所述存储的预设阈值进行比较，基于比较结果可以判断出实际发射的波束与设计中存在一定偏离，进而据此去调整波束。
本发明实施例还提供了一种基于AiP结构的波束调整方法。通过AiP结构中的ULA阵列检测该ULA阵列对应的UPA阵列发射的信号，将检测到的信号的特征参数值与预设的信号特征参数值进行比较，基于比较结果调节与所述UPA阵列相连的移相器，直至达到最优波束配置，并存储所述最优波束配置。所述方法可以应用于AiP结构安装于终端设备时，此时AiP周边的电路器件和外壳等成为确定的物理环境，当UPA阵列发射特定的信号时，通过对应的ULA阵列可以检测到相对固定的信号。由于AiP结构周围存在一定的遮挡(即周边的电路器件和外壳等)，检测到的信号特征参数值与预设的信号特征参数值存在一定差异，通过调节相应的移相器使得AiP达到最优波束配置。
本发明实施例还提供了一种天线模块选择方法和装置，通过AiP中的ULA阵列检测对应的UPA阵列发射的信号，将终端设备中多个 AiP检测到的信号的特征参数值与对应的预设特征参数值进行比较，基于比较结果选择波束性能最好的AiP用于终端设备的信号收发。因此，实现了终端对波束的本地检测和管理，并且无需增加额外硬件，节省了网络资源，减小了终端的成本和功耗。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例作详细的说明。
参考图1，图1示出了本发明一实施例提供的AiP。所述AiP包括一组由多个天线单元101构成的ULA天线阵列和一组由多个天线单元102构成的UPA天线阵列，图1以每组天线阵列包括八个天线单元为例。在一些实施例中，一个AiP也可以包括多组ULA天线阵列和多组UPA天线阵列，ULA天线阵列和UPA天线阵列的数量一致，且ULA天线阵列与UPA天线阵列包含的天线单元数一致，形成一一对应的关系。
UPA阵列是AiP的主阵列，由于相控阵列在波束指向侧方一定角度后出现主瓣增益下降同时旁瓣增益上升的问题，一般设定主阵列UPA在某个最大工作角度外不再作为工作通道，而此空间区域由ULA阵列覆盖。因此AiP中同时设计有UPA和ULA至少两组阵列，并为它们配置相应独立的电路与控制处理通道。
参考图2，图2示出了本发明一实施例提供的基于AiP结构的波束检测方法的流程图，以下对具体步骤进行详细说明。
在一些实施例中，所述AiP结构至少包括第一AiP，所述第一AiP包括至少一个ULA阵列和对应的至少一个UPA阵列。
步骤S201中，所述第一AiP中的ULA阵列检测对应的所述UPA阵列发射的信号。
当AiP结构设计定型后，ULA阵列与UPA阵列之间即形成了固定的物理通道。当UPA阵列发射特定的信号时，由于UPA阵列和ULA阵列之间的耦合关系，ULA阵列的通道可以检测到相对固定的 信号。
在一些实施例中，所述UPA阵列发射的信号为毫米波信号。
在一些实施例中，每个ULA阵列包括多个天线单元，每个UPA阵列也包括多个天线单元，并且所述ULA阵列包含的多个天线单元的数量与所述UPA阵列包含的多个天线单元的数量相等。在一些实施例中，所述ULA阵列检测对应的所述UPA阵列发射的毫米波信号可以包括：所述ULA阵列包括的多个天线单元分别检测对应的所述UPA阵列包括的多个天线单元发射的信号。
步骤S203中，存储第一组检测结果，所述第一组检测结果包括所述第一AiP中的ULA阵列检测到的所述第一AiP中的UPA阵列发射的信号的特征参数值。
在一些实施例中，所述第一组检测结果包括以下参数的任意组合：所述第一AiP中的ULA阵列检测到的所述第一AiP中的UPA阵列发射的信号对应的波束的方向角、主瓣和旁瓣的比值、旁瓣抑制和波束的功率。
在一些实施例中，所述第一组检测结果存储在查找表中。所述查找表设置于基带处理器中，所述基带处理器和所述AiP结构之间由射频前端电路连接。

参考图4，图4示出了本发明一实施例提供的基于AiP结构的波束调整方法的流程图，所述波束调整方法基于上述波束检测方法中存储的检测结果来进行。以下对具体步骤进行详细说明。

步骤S401中，所述第一AiP中的ULA阵列检测对应的所述UPA阵列发射的信号。
当AiP结构安装到终端设备后，不仅ULA阵列与UPA阵列之间形成有固定的物理通道，AiP周边的电路器件和终端设备的外壳等也成为确定的物理环境。当UPA阵列发射特定的信号时，ULA阵列可以检测到相对固定的信号。与安装到终端设备前相比，由于存在一定的遮挡，天线阵列发射的信号对应的波束会受到影响。
在一些实施例中，所述UPA阵列发射的信号为毫米波信号。
在一些实施例中，每个ULA阵列包括多个天线单元，每个UPA阵列也包括多个天线单元，并且所述ULA阵列包含的多个天线单元的数量与所述UPA阵列包含的多个天线单元的数量相等。在一些实 施例中，所述ULA阵列检测对应的所述UPA阵列发射的信号可以包括：所述ULA阵列包括的多个天线单元分别检测对应的所述UPA阵列包括的多个天线单元发射的信号。
步骤S403中，将所述检测到的信号的特征参数值与预设的第一组信号特征参数值进行比较。
当AiP结构安装到终端设备后，AiP周边的电路器件和终端设备的外壳等会对AiP结构形成一定的遮挡。此时天线阵列发射的信号对应的波束与AiP结构完成设计定型时相比存在一定的偏离，影响性能。因此，需要基于此偏离对天线阵列进行一定的调整，使得相应的波束接近最初设计时的预设阈值，
在一些实施例中，所述检测到的信号的特征参数值包括以下参数的任意组合：所述第一AiP中的ULA阵列检测到的所述UPA阵列发射的信号对应的波束的方向角、主瓣和旁瓣的比值、旁瓣抑制和波束的功率。
在一些实施例中，所述预设的第一组信号特征参数值包括：当所述AiP结构处于无遮挡状态时，所述ULA阵列检测到对应的所述UPA阵列发射的信号的特征参数值，即上述波束检测方法的步骤S203中存储的第一组检测结果。

所述波束调整方法应用于所述AiP结构安装于终端设备后，此时AiP结构的遮挡来自于周围的电路器件和终端设备的外壳，通过步骤S405中的调节后，AiP结构中的UPA阵列发射的信号对应的波束达到了最优配置。
如上所述，可以通过一个AiP中的ULA阵列去检测该AiP中对应的UPA阵列发射的信号。为进一步提高实际环境中的全向通信能力并实现MIMO功能，所述AiP结构可以包括多个AiP，所述多个AiP被布置于各个方向协同工作。此时多个AiP之间也形成了固定的物理通道。当某个AiP中的UPA阵列发射信号时，其他AiP中的ULA阵列也可以检测到相对固定的信号，从而调整波束。
具体的，当所述AiP结构包括多个AiP时，比如第一AiP和第二AiP，所述波束调整方法还包括：第二AiP中的ULA阵列检测所述第一AiP中的UPA阵列发射的信号；将所述第二AiP中的ULA阵列检测到的所述第一AiP中的UPA阵列发射的信号的特征参数值与预设的第二组信号特征参数值进行比较；基于比较结果调节与所述第一AiP中的UPA阵列相连的移相器，直至达到第二最优波束配置。
所述第二AiP中的ULA阵列检测到的所述第一AiP中的UPA阵列发射的信号的特征参数值包括以下参数的任意组合：检测到的所述UPA阵列发射的信号对应的波束的方向角、主瓣和旁瓣的比值、旁瓣抑制和波束的功率。
类似的，所述预设的第二组信号特征参数值包括：当所述AiP结 构处于无遮挡状态时，所述第二AiP中的ULA阵列检测到所述第一AiP中的UPA阵列发射的信号的特征参数值，即上述波束检测方法中存储的第二组检测结果。
类似的，所述达到第二最优波束配置包括：所述第二AiP中的ULA阵列检测到的所述第一AiP中的UPA阵列发射的信号对应的波束的功率与预设的功率的偏差位于10％以内、和/或旁瓣抑制与预设的旁瓣抑制的偏差位于10％以内。
在一些实施例中，可以综合考虑同一AiP的检测结果和不同AiP之间的检测结果来调节移相器、调整波束。
当所述AiP结构包括多个AiP时，每个AiP中的ULA阵列均可以检测所述AiP中对应的所述UPA阵列发射的信号，将所述检测到的信号的特征参数值与该组所述UPA阵列预设的信号特征参数值进行比较，并基于比较结果调节与所述UPA阵列相连的相移器，直至分别达到对应的最优波束配置。
在一些实施例中，所述波束调整方法还包括：所述第二AiP中的ULA阵列检测所述第二AiP中的UPA阵列发射的信号；将所述第二AiP中的ULA阵列检测到的所述第二AiP中的UPA阵列发射的信号的特征参数值与预设的第三组信号特征参数值进行比较；以及基于比较结果调节与所述第二AiP中的UPA阵列相连的相移器，直至达到第三最优波束配置。
类似的，所述预设的第三组信号特征参数值包括：当所述AiP结构处于无遮挡状态时，所述第二AiP中的ULA阵列检测到所述第二AiP中的UPA阵列发射的信号的特征参数值。

上述实施例提供的波形调整方法中对每个AiP存储所述最优波束配置的意义在于：当包括所述AiP结构的终端设备投入实际应用中时，其周围将存在更多的遮挡，可以将检测到的信号的参数值与所述存储的最优波束配置进行比较，基于比较结果可以选择基于性能最好的AiP进行信号收发。

如上实施例所述，所述预设的第一组、第二组、第三组信号特征参数值包括：当所述AiP结构处于无遮挡状态时，所述ULA阵列检测到相关的所述UPA阵列发射的信号的特征参数值。也就是所述AiP结构刚设计定型好还未装入终端设备时，所述ULA阵列检测到相关的所述UPA阵列发射的信号的特征参数值。
参考图6，图6示出了本发明一实施例提供的天线模块选择方法的流程图，所述天线模块选择方法应用于终端设备，基于上述波束调整方法中存储的最优波束配置来进行。所述终端设备包括多个AiP，比如第一AiP和第二AiP，每个AiP包括至少一个ULA阵列和对应的至少一个UPA阵列。所述多个AiP置于所述终端设备内的不同位置。
当UPA阵列发射特定的信号时，由于UPA阵列和ULA阵列之间的耦合关系，ULA阵列的通道可以检测到相对固定的信号。
步骤S601中，所述第一AiP中的ULA阵列检测所述第一AiP中对应的UPA阵列发射的信号，将检测到的所述第一AiP中对应的UPA阵列发射的信号的特征参数值与预设的第一组特征参数值进行比较，获得第一比较结果。

当AiP应用到终端设备后，除了AiP周边的电路器件和终端设备的外壳，AiP还会受到手持及其它人体遮挡、终端设备附近其它对射频传播产生反射或折射的物体等等。由于这些遮挡，此时天线阵列发射的信号对应的波束与AiP应用到终端设备前相比存在一定的偏离，即波束的性能与预设的会存在一定差距。终端设备中的多个AiP置于所述终端设备内的不同位置，因此每个AiP在同一时刻受到的遮挡程度不尽相同，为了保证通信质量，需要选择与预设性能差距最小的AiP来进行终端设备的信号收发。

在一些实施例中，所述使用所述第一AiP或所述第二AiP用于所述终端设备的信号收发包括：使用所述第一AiP中的所述UPA阵列用于所述终端设备的信号收发，或者使用所述第二AiP中的所述UPA阵列用于所述终端设备的信号收发。

由于每个AiP会放置在终端设备的不同位置，因此不同时刻每个AiP受遮挡的程度不尽相同，即每个AiP发射的信号对应的波束质量不尽相同，可以利用上述实施例提供的方法实时检测、比较，实现AiP之间的动态切换，以保证更优的通信质量。
