在本申请实施例中，以第一通信单元110为Wi-Fi通信单元，第一射频信号为Wi-Fi信号，第二通信单元120蓝牙通信单元，第二射频信号为蓝牙信号为例进行说明。需要说明的是，本申请实施例中的Wi-Fi信号可指2.4G WI-FI信号，2.4G WI-FI信号的频段为2400-2483.5MHz，蓝牙信号的频段为2402-2483.5MHz，本申请实施例中的第一通信单元110和第二通信单元120采用同频段同时工作。第一通信单元110可同时分别与两个射频通路130连接，这样第一通信单元110可经两个射频通路130分别对应连接至两支天线ANT，可以支持对无线保真信号的两路发射和双路接收，以使通信设备的Wi-Fi通信可以保持在MIMO工作状态。第二通信单元120可切换连接至任一射频通路130，可以理解的是，第二通信单元120可切换连接至任一天线ANT，以支持对蓝牙信号的单路发射和接收。
在本申请实施例中，第一通信单元110和第二通信单元120可以为两个独立的通信单元，可以为一个集成的通信单元，例如短距离无线通信处理器(例如，WI-FI&BT芯片)。示例性的，短距离无线通信处理器可用于完成数字信号到射频信号的转换和逆转换过程，包括数字信号的封装成帧，数模信号的转换，调制，上变频等等过程，最终生成了相应的WI-FI信号或者蓝牙信号，或者接收到信号后经过一系列逆过程送到中央处理器。其中，逆过程可包括下变频，解调，模数信号的转换，解封装等过程。
在一个实施例中，如图2所示，提供了一种无线通信方法，以该方法应用于图1中的通信设备为例进行说明，包括以下步骤：
步骤202，分别获取第一通信单元和第二通信单元的工作状态，工作状态包括扫描状态和连接状态。
通信设备可以直接获取第一通信单元110和第二通信单元120的工作状态。其中，第 一通信单元110和第二通信单元120的工作状态可至少包括扫描状态、连接状态。
当通信设备启动对应无线通信(例如，Wi-Fi、蓝牙通信)技术的扫描功能后，通信设备可以主动发送扫描信号，以发现通信设备周围的能够与通信设备建立网络连接的其它设备。通信设备可以通过检测扫描信号来确定通信单元的工作状态是否处于扫描状态。可选的，通信设备还可以基于其他相关技术检测第一通信单元110和第二通信单元120是否处于扫描状态。
连接状态可包括建立网络连接的过程状态和成功建立了网络连接的连接状态。当通信设备处于连接状态时，可以支持对对应通信信号的接收和发射中至少一个。示例性的，通信设备可以基于主动发起的Wi-Fi连接请求和蓝牙连接请求，以及接收的Wi-Fi连接请求、蓝牙连接请求，以及Wi-Fi网络连接状态信息、蓝牙网络连接状态信息等来确定第一通信单元110和第二通信单元120的工作状态是否处于连接状态。可选的，通信设备还可以基于其他相关技术检测第一通信单元110和第二通信单元120是否处于连接状态。可选的，第一通信单元110和第二通信单元120还可包括广播状态、待机状态的其他工作状态，在本申请实施例中，第一通信单元110和第二通信单元120的工作状态不限于上述举例说明。
步骤204，根据第一通信单元的第一工作状态和第二通信单元的第二工作状态，确定第二通信单元的目标射频通路。
其中，第二通信单元120的目标射频通路为与第二通信单元120导通连接的射频通路130。第二通信单元120可通过目标射频通路来实现对第二通信信号的收发。目标射频通路为至少两个射频通路130中的一个。
第一工作状态和第二工作状态可以相同，也可以不同。通信设备可根据第一工作状态和第二工作状态可确定第一通信单元110和第二通信单元120的通信优先级，并根据通信优先级确定目标射频通路。其中，通信优先级越高，通信需求量也就越大，则需要配置通信性能越好的射频通路130，也可以理解为，则需要配置通信性能越好的天线。需要说明的是，本申请实施例中的射频通路130对应连接至一支唯一的天线ANT。在默认状态下，通信设备可预先存储每一射频通路130的通信性能，并对其进行标识、排序。其中，默认状态可以理解为通信设备无遮挡，无外界环境因素影响其通信性能。
步骤206，在目标射频通路与第一通信单元连接的情况下，控制第一通信单元和第二通信单元复用目标射频通路。
第一通信单元110可同时与两个射频通路130连接，第二通信单元120仅与目标射频通路导通连接。若通信设备仅包括两个射频通路130，则第二通信单元120的目标射频通路与第一通信单元110的射频通路130复用。若通信设备包括三个及以上的射频通路130，第二通信单元120的目标射频通路可以不与第一通信单元110的射频通路130复用，可以理解为目标射频通路不与第一通信单元110连接，通信设备可控制第二通信单元120与目标射频通路导通连接。
可选的，若通信设备包括三个及以上的射频通路130，第二通信单元120的目标射频通路可与第一通信单元110的射频通路130复用，可以理解为目标射频通路与第一通信单元110连接。在此情况下，通信设备可控制第一通信单元110和第二通信单元120复用该目标射频通路。本申请实施例中的通信设备被配置有多种复用模式，例如可包括频分双工复用(Frequency Division Duplexing，FDD)模式和时分双工复用(Time Division Duplex，TDD)模式。在目标射频通路与第一通信单元110连接的情况下，通信设备可基于第一通信单元110和第二通信单元120的工作状态来配置第一通信单元110和第二通信单元120复用目标射频通路的复用模式，以实现蓝牙通信和Wi-Fi通信复用同一射频通路130。
上述无线通信方法，应用于包括第一通信单元110、第二通信单元120和至少两个射频通路130的通信设备中，无线通信方法包括分别获取第一通信单元110和第二通信单元120的工作状态，根据第一通信单元110的第一工作状态和第二通信单元120的第二工作 状态，确定第二通信单元120的目标射频通路，在目标射频通路与第一通信单元110连接的情况下，控制第一通信单元110和第二通信单元120复用目标射频通路，这样，可以在确保第一通信单元110支持两路信号的同时，可基于第一通信单元110和第二通信单元120的工作状态动态调整第二通信单元120的目标射频通路，并在第一通信单元110和第二通信单元120复用目标射频通路时还可以动态调整其复用模式，可以避免同频干扰，实现第一通信信号和第二通信信号的同时发射，还可以避免第一通信单元110和第二通信单元120在与对端设备通信过程中出现丢包或重传等情况的发生，提高了同时传输第一通信信号和第二通信信号的吞吐量、时延等通信性能。
在其中一个实施例中，根据第一通信单元110的第一工作状态和第二通信单元120的第二工作状态，确定第二通信单元120的目标射频通路，包括：当第一工作状态和第二工作状态的工作状态相同时，确定任一射频通路130为目标射频通路。
其中，若第一通信单元110的第一工作状态和第二通信设备的第二工作状态相同，例如均为扫描状态或者是连接状态时，可确定多个射频通路130中的任一个为第二通信单元120的目标射频通路。可选的，若多个射频通路130包括第一射频通路、第二射频通路，则第一通信单元110分别与第一射频通路、第二射频通路连接；第二通信单元120与目标射频通路连接，其中，目标射频通路为第一射频通路或第二射频通路。可选的，若多个射频通路130包括第一射频通路、第二射频通路和第三射频通路，例如，第一通信单元110可分别与第一射频通路、第二射频通路连接，第二通信单元120与目标射频通路连接，其中，目标射频通路为第一射频通路、第二射频通路和第三射频通路中的一个。
在本申请实施例中，若第一通信单元110和第二通信单元120的工作状态相同，则可以从任一射频通路130中确定第二通信单元120的目标射频通路，这样可以均衡配置第一通信单元110和第二通信单元120的射频通路130，使其第一通信单元110和第二通信单元120可基于相对均衡的射频通路130来实现相应通信信号的收发，同时满足第一通信单元110和第二通信单元120的通信需求。
如图3所示，在其中一个实施例中，若第一通信单元110的第一工作状态和第二通信单元120的第二工作状态均为扫描状态，在目标射频通路与第一通信单元110连接的情况下，控制第一通信单元110和第二通信单元120复用目标射频通路，具体可包括：步骤306，在目标射频通路与第一通信单元110连接的情况下，控制第一通信单元110和第二通信单元120采用时分双工模式复用目标射频通。示例性的，若目标射频通路为第一射频通路，则通信设备可分时控制第一通信单元110和第二通信单元120复用第一射频通路。
请继续参考图3，可选的，若第一通信单元110的第一工作状态和第二通信单元120的第二工作状态均为扫描状态，在目标射频通路与第一通信单元110连接的情况下，控制第一通信单元110和第二通信单元120复用目标射频通路，具体可包括：步骤308，在目标射频通路与第一通信单元连接的情况下，控制第一通信单元和第二通信单元采用频分双工模式复用目标射频通路。其中，频分双工模式中，第一通信单元110和第二通信单元120复用目标射频通路的信道间隔大于第一预设信道带宽。
在其中一个实施例中，第一预设信道带宽根据第一通信单元110的第一工作状态和第二通信单元120的第二工作状态确定。在第一工作状态和第二工作状态都是扫描状态下，可以将第一预设信道带宽设置的稍微大一些，以提高Wi-Fi通信和蓝牙通信之间的隔离度，当然也不能设置的过于大，以避免影响Wi-Fi信号和蓝牙信号各自的工作信道带宽的有效带宽。示例性的，第一预设信道带宽可以为15MHz-25MHz。在本申请实施例中，对第一预设信道带宽的具体数值不做进一步的限定。
本实施例中，通信设备可控制第一通信单元110和第二通信单元120采用频分双工模式复用目标射频通路，且仅需要保证复用目标射频通路的信道间隔大于第一预设信道带宽，这样就在避免同频干扰的情况下，实现第一通信信号和第二通信信号的同时发射，还 可以避免第一通信单元110和第二通信单元120在与对端设备通信过程中出现丢包或重传等情况的发生，可以提高第一通信单元110和第二通信单元120各自的通信性能。
如图4所示，在其中一个实施例中，若第一通信单元110和第二通信单元120的工作状态均为连接状态时，其中，在目标射频通路与第一通信单元110连接的情况下，控制第一通信单元110和第二通信单元120复用目标射频通路包括步骤406，在目标射频通路与第一通信单元连接的情况下，控制第一通信单元和第二通信单元采用时分双工模式复用目标射频通路。
若工作状态为连接状态，则对通信性能的要求要高于工作状态为扫描状态的通信性能的要求。第一通信单元110和第二通信单元120均工作在连接状态，则需要实现对相应通信信号的接收和/或发射。此时，通信终端可控制第一通信单元110和第二通信单元120采用时分双工模式复用目标射频通路，以满足第一通信单元110和第二通信单元120的通信需求。
在其中一个实施例中，根据第一通信单元110的第一工作状态和第二通信单元120的第二工作状态，确定第二通信单元120的目标射频通路，包括：当第一工作状态和第二工作状态不同时，根据各射频通路130的接收性能数据确定第二通信单元120的目标射频通路的步骤。
连接状态的通信优先级高于扫描状态的通信优先级。若第一通信单元110的工作状态为扫描状态，第二通信单元120的工作状态为连接状态，可确定具有最大接收性能的射频通路130为目标射频通路。示例性的，通信设备可控制第二通信单元120分别分时切换连接至每一射频通路130，针对每一导通连接的射频通路130可获取第二通信信号的接收性能数据。其中，接收性能数据可包括但不限于接收信号强度(received signal strength indication，RSSI)、接收的参考信号功率(reference signal received power，RSRP)、信号与噪声比(signal-to-noise ratio，SNR)等。通信设备可基于每一射频通路130的接收性能数据筛选出具有最大接收性能数据的射频通路130作为目标接收通路，并使第二通信单元120导通连接至目标射频通路。示例性的，以RSSI为例，若多个射频通路130中，基于第三射频通路接收的第二通信信号的RSSI值最大，则确定第二通信单元120的目标射频通路为第三射频通路。
本实施例中，若第一通信单元110和第二通信单元120的工作状态不同，则可根据各自的工作状态确定通信优先级，其中，通信优先级越高，其对应通信单元配置的射频通路130的通信性能也就越高。示例性的，若第二通信单元120的工作状态为连接状态，则其通信优先级高于第一通信单元110的通信优先级，则可以确定具有最大接收性能的射频通路130为第二通信单元120的目标射频通路，以优先确保第二通信单元120工作在连接状态的通信性能，同时可以为第一通信单元110配置选择其他射频通路以保证第一通信单元110能够正常进行扫描。
如图5所示，在其中一个实施例中，若第一工作状态为扫描状态，第二工作状态为连接状态，在目标射频通路与第一通信单元110连接的情况下，控制第一通信单元110和第二通信单元120复用目标射频通路包括步骤506：在目标射频通路与第一通信单元连接的情况下，控制第一通信单元和第二通信单元采用时分双工模式复用目标射频通路。
示例性的，通信设备配置有第一射频通路和第二射频通路，通信设备可选择通信性能最优的射频通路130为目标射频通路。若第一射频通路为第二通信单元120的目标射频通路，通信设备可控制第二通信单元120与第一射频通路导通连接，同时，第一通信单元110可同时与第一射频通路、第二射频通路连接。也即，第一通信单元110和第二通信单元120可复用第一射频通路。具体的，通信设备可控制第一通信单元110和第二通信单元120采用时分双工模式复用目标射频通路。这样，在优先保证第一通信单元110的通信性能的情况下，可以避免同频干扰，提高第一通信信号和第二通信信号在传输过程中的隔离度，进 而可提高第一通信单元110和第二通信单元120各自的通信性能。
为了便于说明，以通信设备配置有第一射频通路、第二射频通路和第三射频通路为例进行说明。其中，若第一通信单元110分别与第一射频通路、第二射频通路连接，第三射频通路为第二通信单元120的目标射频通路，此时，第一通信单元110和第二通信单元120各自采用独立的射频通路130进行通信，不复用同一射频通路。在此情况下，通信设备可采用频分双工模式同时控制第一通信单元110基于第一射频通路、第二射频通路实现对第一通信信号的发射，以及同时控制第二通信单元120采用第三射频通路实现对第二通信信号的发射。这样，通信终端可基于配置的三个射频通路130，控制第一通信单元110和第二通信单元120采用不同的射频通路130来实现通信，可以在实现发射第一通信信号和第二通信信号的同时，还可以避免同频干扰，提高第一通信信号和第二通信信号在传输过程中的隔离度，进而可提高第一通信单元110和第二通信单元120各自的通信性能。
可选的，若第一射频通路为第二通信单元120的目标射频通路，则通信设备可控制第一通信单元110和第二通信单元120采用时分双工模式复用目标射频通路。这样，在优先保证第二通信单元120的通信性能的情况下，可以避免同频干扰，提高第一通信信号和第二通信信号在传输过程中的隔离度，进而可提高第一通信单元110和第二通信单元120各自的通信性能。
在其中一个实施例中，第一工作状态为连接状态，第二工作状态为扫描状态，其中，当第一工作状态和第二工作状态不同时，根据各射频通路130的接收性能数据确定第二通信单元120的目标射频通路。连接状态的通信优先级高于扫描状态的通信优先级。若第一通信单元110的工作状态为连接状态，第二通信单元120的工作状态为扫描状态，可确定具有最大和次大接收性能的射频通路130作为第一通信单元110的射频通路130。若通信设备配置有第一射频通路和第二射频通路，则可以从第一射频通路和第二射频通路中选其一作为第二通信单元120的目标射频通路。若通信设备配置有第一射频通路、第二射频通路和第三射频通路，其中，第二通信单元120的目标射频通路为未与第一通信单元110导通连接的射频通路130。这样，第一通信单元110和第二通信单元120可基于各自配置的射频通路130进行通信，无须复用同一射频通路130。
本实施例中，若第一通信单元110和第二通信单元120的工作状态不同，则可根据各自的工作状态确定通信优先级，其中，通信优先级越高，其对应通信单元配置的射频通路130的通信性能也就越高。示例性的，若第一通信单元110的工作状态为连接状态，则其通信优先级高于第二通信单元120的通信优先级，则可以确定具有最大、次大接收性能的射频通路130为第一通信单元110的目标射频通路，以优先确保第一通信单元110工作在连接状态的通信性能，同时可以为第二通信单元120配置选择其他射频通路130以保证第二通信单元120能够正常进行扫描。
请继续参考图5，在上述实施例第一工作状态为连接状态，第二工作状态为扫描状态的基础上，在目标射频通路与第一通信单元110连接的情况下，控制第一通信单元110和第二通信单元120复用目标射频通路包括步骤508，在目标射频通路与第一通信单元连接的情况下，控制第一通信单元和第二通信单元采用频分双工模式复用目标射频通路。其中，第一通信单元110和第二通信单元120复用目标射频通路的信道间隔大于第二预设信道带宽。
在其中一个实施例中，第二预设信道带宽根据第一通信单元110的第一工作状态和第二通信单元120的第二工作状态确定。在第一工作状态为连接状态和第二工作状态为扫描状态下，可以将第一预设信道带宽设置的稍微小一些，以提高Wi-Fi通信和蓝牙通信的有效带宽，当然也不能设置的过于小，以避免Wi-Fi信号和蓝牙信号传输过程中的同频干扰。示例性的，第二预设信道带宽可以为5MHz-10MHz。在本申请实施例中，对第二预设信道带宽的具体数值不做进一步的限定。
在本实施例中，第二通信单元120处于扫描状态，第一通信单元110处于连接状态，第二通信单元120的通信优先级低于第一通信单元110的通信优先级，在确保第一通信单元110的通信性能的前提下，通信设备可以采用频分双工模式控制第一通信单元110和第二通信单元120复用目标射频通路的信道间隔大于第二预设信道带宽。如此，第一通信单元110和第二通信单元120在复用目标射频通路时，既可以确保第一通信单元110在连接状态的通信性能，也可以确保第二通信单元120在扫描状态的通信性能，同时，还可以避免复用同一射频通路130的同频干扰，可提高第一通信信号和第二通信信号在传输过程中的隔离度，进而可提高第一通信单元110和第二通信单元120各自的通信性能。
如图6所示，在其中一个实施例中，无线通信方法包括步骤602-步骤606。
步骤602，分别获取第一通信单元和第二通信单元的工作状态，工作状态包括扫描状态和连接状态。
步骤604，根据第一通信单元的第一工作状态和第二通信单元的第二工作状态，确定第二通信单元的目标射频通路。
步骤602、步骤604可参考前述步骤202、步骤204，在此，不再赘述。
步骤606，在目标射频通路未与第一通信单元导通连接的情况下，控制第一通信单元和第二通信单元采用频分双工模式彼此独立工作。
通信设备配置有第一射频通路、第二射频通路和第三射频通路，其中，第二通信单元120的目标射频通路未与第一通信单元110连接，则通信设备可控制第一通信单元110和第二通信单元120采用频分双工模式彼此独立工作。在本申请实施例中，无论第一通信单元和第二通信单元的工作状态如何，只要第二通信单元120的目标射频通路未与第一通信单元110连接，通信设备都可控制第一通信单元110和第二通信单元120采用频分双工模式彼此独立工作。
示例性的，第一通信单元110可分别与第一射频通路、第二射频通路连接，若根据第一通信单元110的第一工作状态和第二通信单元120的第二工作状态，确定第二通信单元120的目标射频通路为第三射频通路，则可控制第二通信单元120与第三射频通路连接。第一通信单元110和第二通信单元120可分别采用独立的射频通路130进行通信，不复用同一射频通路130。在此情况下，通信设备可采用频分双工模式同时控制第一通信单元110基于第一射频通路、第二射频通路实现对第一通信信号的发射，以及同时控制第二通信单元120采用第三射频通路实现对第二通信信号的发射，还可以避免同频干扰，提高第一通信信号和第二通信信号在传输过程中的隔离度，进而可提高第一通信单元110和第二通信单元120各自的通信性能。另外，通信设备配置有三个射频通路，可以根据各个通信单元的工作状态来实现第二通信单元120的目标射频通路的切换，同时通信终端也具有从频分双工复用模式切换至时分双工复用模式的能力，可以提高通信设备的应用多样性，以在任何通信场景下，都可以提高多种不同制式的短距离无线通信工作在同一工作频段的通信性能。
应该理解的是，虽然流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，流程图中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。

其中，处理电路101分别与第一通信单元110、第二通信单元120连接，其可作为通信设备的处理和控制中心。示例性的，处理电路101可包括中央处理器，可用于对第一通信单元110、第二通信单元120输出的信号进行分析处理，并可用于获取第一通信单元110、第二通信单元120的工作状态、各射频通路130的导通状态、以及支持对各射频通路130的接收性能分析等。

在确定第二通信单元120的目标射频通路时，若第一通信单元110和第二通信单元120的工作状态相同，则可确定任一射频通路130为第二通信单元120的目标射频通路。若第二通信单元120的第二工作状态为连接状态，第一通信单元110的第一工作状态为扫描状态，则可根据各接收通路的接收性能数据确定第二通信单元120的目标射频通路。其中，该目标射频通路对应的接收性能数据最优。若第一通信单元110的第一工作状态为连接状态，第二通信单元120的第二工作状态为扫描状态，第二通信单元120的目标射频通路可以为第三射频通路133。
当第二通信单元120的目标射频通路为第一射频通路131或第二射频通路132时，处理电路101可控制第一通信单元110和第二通信单元120复用目标射频通路。其中，复用目标射频通路的复用方式可参考前述仅包括第一射频通路131和第二射频通路132的实施例，在此，不再赘述。
当第二通信单元120的目标射频通路为第三射频通路133时，处理电路101可控制第一通信单元110和第二通信单元120采用频分双工模式彼此独立工作。如此，第一通信单元110和第二通信单元120的射频通路130彼此独立，可以实现WI-FI信号和蓝牙信号的同时发射，且可降低WI-FI信号和蓝牙信号之间的干扰，还可以使得第三射频通路133和第三天线ANT的布局更为灵活，提高了各天线ANT之间的隔离度。
如图11所示，可选的，与如图9所示的实施例不同的是，第一通信单元110可通过开关电路140切换连接至第一射频通路131、第二射频通路132和第三射频通路133中的两个，第二通信单元120可通过开关电路140连接至第一射频通路131、第二射频通路132、第三射频通路133中的一个。
在确定第二通信单元120的目标射频通路时，若第一通信单元110和第二通信单元120的工作状态相同，则可确定任一射频通路130为第二通信单元120的目标射频通路。若第二通信单元120的第二工作状态为连接状态，第一通信单元110的第一工作状态为扫描状态，则可根据各接收通路的接收性能数据确定第二通信单元120的目标射频通路。其中，该目标射频通路对应的接收性能数据最优。若第一通信单元110的第一工作状态为连接状态，第二通信单元120的第二工作状态为扫描状态，则可根据各接收通路的接收性能数据确定第一通信单元110的第一目标射频通路。第一目标射频通路包括接收性能数据最优的射频通路130和接收性能数据次优的射频通路130，而第二通信单元120的目标射频通路 可以为第一射频通路131、第二射频通路132、第三射频通路133中的任一个。示例性的，第二通信单元120的目标射频通路可以为除第一目标射频通路以外的射频通路130。
当第二射频通路132的目标射频通路未与第一通信单元110连接时，处理电路101可控制第一通信单元110和第二通信单元120采用频分双工模式彼此独立工作。如此，第一通信单元110和第二通信单元120的射频通路130彼此独立，可以实现WI-FI信号和蓝牙信号的同时发射，且可降低WI-FI信号和蓝牙信号之间的干扰，还可以使得第三射频通路133和第三天线ANT的布局更为灵活，提高了各天线ANT之间的隔离度。
图12为一个实施例的无线通信装置的结构框图。其中，无线通信装置包括状态获取模块1210、目标确定模块1220和通路复用模块1230。其中，状态获取模块1210，用于分别获取第一通信单元和第二通信单元的工作状态，工作状态包括扫描状态和连接状态。目标确定模块1220，用于根据第一通信单元的第一工作状态和第二通信单元的第二工作状态，确定第二通信单元的目标射频通路，目标射频通路为至少两个射频通路中的一个。通路复用模块1230，用于在目标射频通路与第一通信单元连接的情况下，控制第一通信单元和第二通信单元复用目标射频通路。
