相关申请的交叉引用
本申请要求享有于2019年4月24日提交的名称为“天线调节方法、装置及终端”的中国专利申请201910334978.4的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本申请属于无线通信技术领域，尤其涉及一种天线调节方法、装置及终端。
背景技术
目前，无线保真(Wireless Fidelity，WiFi)一般采用多输入多输出(Multiple Input Multiple Output，MIMO)模式通讯，其在较优的天线环境下可以提升通讯速率；但是，在比较恶化的天线环境下，WiFi就被回退至单输入单输出(Single Input and Single Output，SISO)模式通讯，以改善通讯的可靠性和质量。
当前，为了检测天线环境是否发生恶化，普遍的做法是在确认误包、丢包等情况发生之后，开始监测当前天线环境，一旦发现天线环境恶化，就由MIMO模式切换至SISO模式。上述方法虽然能发现天线环境恶化，但是需要损失一定量的数据；因此，上述方法并不适用于对丢包率比较敏感的使用场景，例如WiFi通话(Voice over WiFi，VoWiFi)中的应用场景，会明显降低用户体验。
申请内容

根据本申请第一方面前述任一实施方式，在保持SISO模式之后，方法还包括：在SISO模式下，向外部设备发送第二广播消息，第二广播消息包括第一指示信息，第一指示信息用于指示外部设备将自身的天线的工作模式切换为SISO模式。
根据本申请第一方面前述任一实施方式，在保持SISO模式之后，方法还包括：在SISO模式下，向外部设备发送数据封包，数据封包包括第二指示信息，第二指示信息用于指示外部设备将自身的天线的工作模式切换为SISO模式。

具体实施方式
下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。
图1为本申请实施例的一种天线调节方法。如图1所示，该天线调节方法可以包括：
S101：在多个天线处于SISO模式的情况下，发送第一广播消息，并获取多个天线的辐射效率；
S102：若多个天线中的至少一个天线的辐射效率小于预设阈值，则保持SISO模式。
在本申请实施例中，通过发送第一广播消息，获取终端所处的天线环境，即多个天线的辐射效率，并基于辐射效率和预设阈值进行判断，进而能在终端传输数据之前就了解到当前的天线环境，并在传输数据之前修正天线的工作状态，故不存在因天线环境恶化导致数据误包、丢包的问题；另外，发送第一广播消息是在相邻两次数据传输之间的时隙，不占用传输数据时间，且能针对当前的天线环境给数据封包调整合适的传输模式，提高传输效率。
图2为本申请与相关技术的对比图。在图2中，左侧的处理过程为相关技术的天线调节方法，右侧的处理过程为本申请实施例的天线调节方法。在相关技术中，在数据链路层侦测链路，例如侦测数据速率和误码率等数据，并基于侦测的数据进行控制判断，如果发现误包、丢包等问题，则由物理层控制解决误包、丢包等问题。而本申请实施例中，直接在物理层侦测天线的硬件链路环境，并在天线环境恶化时，针对每一数据封包调整合适的传输模式，能实时的监测链路硬件环境，且也不需要花时间侦测数据速率。其中，传输模式为终端的多个天线的工作模式。
下面以WiFi MIMO通讯系统为一个示例，来说明天线调节的步骤。图3为相关技术的数据传输示意图。其中，WiFi MIMO通讯系统包括C0路和C1路天线。
如图3所示，采用MIMO模式传输数据，采用SISO模式传输确认字符(Acknowledge character，ACK)；在通过MIMO模式传输数据过程中，如果通讯质量不佳，则会存在收不到ACK的情况，即确认丢包了。传输数据时采用MIMO模式，在传输第一广播消息时，会采用最低等级的传输协议，即SISO模式，以确保链路质量的稳定性。
图4为本申请实施例提供的一种数据传输过程的示意图。
如图4所示，在传输第一广播消息时，若侦测到链路上的物理层通讯质量不好，即天线环境恶化，可以采用SISO模式进行下一次传输数据。
在本申请实施例中，能够通过发送第一广播消息，侦测链路上的物理 层通讯质量(即天线状态)，并根据通讯质量调整待传输的数据封包的传输模式，进而针对通讯质量给数据封包调整合适的传输模式，提高传输效率。
另外，在本申请实施例中，由于通过发送第一广播消息，对天线状态进行侦测，不占用传输数据时间，且每一次发送广播消息都会进行侦测，使得每一个数据封包都能有机会选择合适的传输模式，因此，可以避免因天线状态恶化而导致丢包的问题。
在本申请一些实施例中，S102所述的若多个天线中的至少一个天线的辐射效率小于预设阈值，则保持SISO模式。
参照图4，当多个天线中的至少一个天线的辐射效率小于预设阈值时，表明天线环境恶化，那么在使用SISO模式发送第一广播消息，且接收到外部设备发送的回应消息之后，继续使用SISO模式向外部设备发送数据封包。
在本申请一些实施例中，在S102之后，天线调节方法还包括：
若多个天线中的每一个天线的辐射效率均大于或等于预设阈值，则将SISO模式切换为MIMO模式。
具体包括：在上次传输数据之后，可以接着发送第一广播消息，并获取当前多个天线的辐射效率；如果多个天线中的每一个天线的辐射效率均大于或等于预设阈值，则将SISO模式切换为MIMO模式。另外，可以在数据传输时隙(即在两次传输数据之间的时间间隔)发送第一广播消息，还可以在发送数据之前，先发送第一广播消息。
图5为本申请实施例提供的另一种传输数据过程的示意图。
参照图5，采用SISO模式发送第一广播消息，并获取当前多个天线的辐射效率，如果多个天线中的每一个天线的辐射效率均大于或等于预设阈值，则在下一次传输数据封包之前，将天线的模式从SISO模式切换为MIMO模式。其中，MIMO通讯系统包括C0路和C1路天线。
另外，在相关技术中，终端会使用SISO模式传输数据一段时间之后，重新尝试使用MIMO模式传输数据，如果仍然失败，则继续使用SISO模式传输数据；或者，终端会监测传输数据过程中信号的强度来确定是否要 采用MIMO模式；如果尝试使用MIMO模式传输数据失败了，那么继续使用SISO模式传输数据。
在本申请一些实施例中，S102中的预设阈值的数目为多个，且每个预设阈值对应多个天线中的一个天线的辐射效率。其中，预设阈值可以基于当前天线环境是否存在丢包的现象而设置，或者可以基于是否影响用户体验度而设置。
在本申请一些实施例中，获取多个天线的辐射效率可以具体包括：
根据多个天线中的任意两个天线间的空间损耗隔离度、任两个天线中的第一天线的发射功率、第一天线的反射功率，确定第一天线的辐射效率；
根据多个天线中的任意两个天线间的空间损耗隔离度、任两个天线中的第二天线的发射功率、第二天线的反射功率，确定第二天线的辐射效率。在一些实施例中，多个天线包括第一天线和第二天线。相应地，获取多个天线的辐射效率可以具体包括：
根据第一天线和第二天线之间的空间损耗隔离度、第一天线的发射功率以及第一天线的反射功率，确定第一天线的辐射效率；根据第一天线和第二天线之间的空间损耗隔离度、第二天线的发射功率以及第二天线的反射功率，确定第二天线的辐射效率。
在本申请一些实施例中，多个天线可以包括2*2MIMO和4*4MIMO。为了方便描述，下文中以2*2MIMO天线为示例进行说明。
多个天线的辐射效率包括任意两个天线之间的辐射效率，则2*2MIMO可以包括4个辐射效率，每个预设阈值对应一个辐射效率。
图6为本申请实施例提供的一种2*2MIMO系统的示意图。
在图6中，2*2MIMO系统拥有A0和A1两个天线，其连接各自的匹配电路M0和M1，且天线和匹配电路组成的辐射单元总效率为E0。具体地，天线A0连接匹配电路M0，天线A0和匹配电路M0组成的辐射单元总效率为E0，天线A1连接匹配电路M1，天线A1和匹配电路M1组成的辐射单元总效率为E1。从天线A0空间至天线A1空间的空间损耗隔离度为I。 匹配电路MO和匹配电路M1的反射系数分别为R0和R1。在每一个链路上设置定向耦合器C0和C1，具体地，在天线A0对应的链路上设置定向耦合器C0，在天线A1对应的链路上设置定向耦合器C1，其检测由匹配电路反射的功率大小以及该链路所接收到的信号能量大小。
在收发管理模块发送第一广播消息时，C0路即天线A0对应的链路发出的数据功率为P0，其在匹配电路M0处一部分会进行反射，通过定向耦合器可以得到反射功率为R0，一部分通过天线A0发射至对应的空间，辐射至空间的功率为P0*E0，因为产品设计完成后两天线之间的隔离度已经确定，因此空间损耗隔离度I也是已知。将C1通路即天线A1对应的链路上能检测到的功率表示为R1，可以得到如下公式：
R0＝P0*(1-E0)
R1＝(P0*E0-I)*E1
则由以上公式可以得到：
第一天线辐射效率E0＝1-R0/P0
第二天线辐射效率E1＝R1/(P0-R0-I)
然后根据两个天线的辐射效率和终端内设置的预设阈值，就可以判断是否需要调整当前天线的传输模式。
如果天线A1的天线环境恶化，即天线A1的辐射效率小于预设阈值，可以在下一次数据发送之前就将MIMO模式切换为天线A0的SISO模式传输。反之，如果当天线A0的天线环境恶化严重，即天线A0的辐射效率小于预设阈值，可以在下一次数据发送之前就将MIMO模式切换为天线A1的SISO模式传输。从而提前获知天线环境，并在天线环境恶化时提前切换传输模式，避免了因丢失数据封包带来的用户体验不佳的问题。
当前多个天线中一般会有一个主天线，当天线环境恶化时，默认主天线处于工作状态。其中，图3、图4和图5中的C0路为主天线A0所在的链路，此时在C0路上才会有SISO时隙。
在本申请一些实施例中，在终端的工作模式改变的情况下，还会通过以下方式告知外部设备，使其也将工作模式切换到与终端相同的工作模式。
以下有几种情况告知外部设备切换工作模式：
第一种情况：在SISO模式下，向外部设备发送第二广播消息；其中，第二广播消息包括第一指示信息，第一指示信息用于指示外部设备将自身的多个天线的工作模式切换为SISO模式。
在终端和外部设备传输数据的过程中，可能会存在传输多个广播消息的情况，此时可以在发送第二广播消息(为发送第一广播消息之后连续发送的消息)的时候，通过第二广播消息中的第一指示信息，告知外部设备，终端的工作状态变化，外部设备在收到第二广播消息之后，就切换到与终端相同的工作模式即可，以便后续进行数据传输。
第二种情况：在SISO模式下，向外部设备发送数据封包；其中，数据封包(此数据包为传输第一广播消息之后，下一次发送的数据包)包括第二指示信息，第二指示信息用于指示外部设备将自身的多个天线的工作模式切换为SISO模式。
在终端给外部设备发送第一广播消息，且接收到外部设备发送的回应消息之后，可以直接发送数据，此时可以在数据封包中增加第二指示信息，其中，可以为数据封包的包头部分携带第二指示信息。
本申请实施例中，广播消息可以为ACK，此时外部设备的回应消息也为ACK；广播消息还可以为信标(Beacon)。
本申请一些实施例中的，外部设备可以为路由器、终端、基站等包括多个天线的设备。
另外，广播消息中还会携带外部设备的ID，在ID对应的外部设备接收到广播消息之后，会发送回应消息；如果不是ID对应的外部设备接收到广播消息，则丢弃即可。
图7为本申请实施例提供的一种天线调节装置的示意图。如图7所示，该天线调节装置包括：
收发管理模块601，用于在多个天线处于SISO模式的情况下，发送第一广播消息；
辐射效率获取模块602，用于获取多个天线的辐射效率；
模式调节模块603，用于在多个天线中的至少一个天线的辐射效率小于预设阈值，保持SISO模式。
在本申请实施例中，通过发送第一广播消息，获取终端所处的天线环境，即多个天线的辐射效率，并基于辐射效率和预设阈值进行判断，进而能在终端传输数据之前就了解到当前的天线环境，并在传输数据之前修正天线的工作状态，故不存在因天线环境恶化导致数据误包、丢包的问题；另外，发送第一广播消息是在相邻两次数据传输之间的时隙，不占用传输数据时间，且能针对当前的天线环境给数据封包调整合适的传输模式，提高传输效率。
在本申请一些实施例中，模式调节模块603还用于：若多个天线中的每一个天线的辐射效率均大于或等于预设阈值，则将SISO模式切换为MIMO模式。
在本申请一些实施例中，预设阈值的数目为多个，多个预设阈值与多个天线的辐射效率一一对应。
在本申请一些实施例中，多个天线包括第一天线和第二天线，辐射效率获取模块602具体用于：
根据第一天线和第二天线之间的空间损耗隔离度、第一天线的发射功率以及第一天线的反射功率，确定第一天线的辐射效率；根据第一天线和第二天线之间的空间损耗隔离度、第二天线的发射功率以及第二天线的反射功率，确定第二天线的辐射效率。
在本申请一些实施例中，第一天线的辐射效率为：E0＝I-R0/P0，第二天线的辐射效率为：E1＝R1/(P0-R0-I)。
其中，R0为第一天线的匹配电路的反馈系数，P0为第一天线的定向耦合器的发射功率；R1为第二天线的匹配电路的反馈系数，I为空间损耗隔离度。
在本申请一些实施例中，收发管理模块601还用于：在SISO模式下，向外部设备发送第二广播消息，第二广播消息用于指示其他终端将自身天线的工作模式切换为SISO模式。
在本申请一些实施例中，收发管理模块601还用于：在SISO模式下，向外部设备发送数据封包，数据封包包括指示信息，指示信息用于指示外部设备将自身天线的工作模式切换为SISO模式。
