为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
下面对本申请实施例涉及的相关名词进行介绍。
SISO：单输入单输出，也即在发射端采用单根发射天线发送信号，在接收端采用单根接收天线来接收信号。
MIMO：多输入多输出，也即在发射端采用多根发射天线各自独立发送信号，在接收端采用多根接收天线来接收信号。需要说明的是，多根发射/接收天线收发的数据流可以是相同的，此时总辐射功率(Total Radiated Power，TRP)和总全向灵敏度(Total Isotropic Sensitivity，TIS)得以提升，进而提升通信距离。多根发射/接收天线收发的数据流也可以是不同的，提升传输速率。
相关技术中，仅根据吞吐量来控制终端天线在SISO模式和MIMO模式之间切换，吞吐量较小时采用SISO模式可能出现通信距离降低、通信掉线等问题，吞吐量较大时采用MIMO模式可能会出现功耗浪费的问题。
基于此，本申请实施例提供一种终端天线的工作模式切换方法，通过在终端处于强信号场景时，基于终端的吞吐量来确定终端天线的工作模式，使得终端天线的工作模式能兼顾通信质量与终端功耗两方面因素，在满足业务需求的前提下节省终端功耗。例如，当终端在目标时段内处于强信号场景且吞吐量较大时，确定终端天线使用MIMO模式，使得终端的TRP和TIS得以提升，进而提升通信质量和通信距离；再例如，当终端在目标时段内处于强信号场景且吞吐量较小时，确定终端天线使用SISO模式，能有效节省终端功耗。
本申请实施例提供的技术方案，各步骤的执行主体为配置有终端天线的终端，该终端天线既支持SISO模式也支持MIMO模式，终端中的处理器还支持 终端天线在SISO模式和MIMO模式之间灵活切换。上述终端可以为智能手机、平板电脑、个人计算机等等。可选地，终端中安装有无线通信芯片，各步骤的执行主体也可以为上述无线通信芯片。
图1示出了本申请一个实施例示出的终端天线的工作模式示意图。在弱信号场景，无论吞吐量高低均采用MIMO模式，通过MIMO模式来弥补信号弱的问题以满足业务需求。在强信号场景下，若吞吐量高，则采用MIMO模式，提升通信质量以满足业务需求，若吞吐量低，此时SISO模式也能满足业务需求，则采用SISO模式以节省终端功耗。
图2示出了本申请一个实施例提供的终端天线的工作模式确定方法的流程图。该方法包括：
步骤201，获取终端在目标时段内的接收信号强度。
接收信号强度用于表征终端接收到的信号质量。接收信号强度可以用RSSI(Received Signal Strength Indication，接收信号强度指示)进行表示。
目标时段可以是任意一个时段。目标时段的时间长度由终端预先设定，或者，由技术人员自定义设定。示例性地，目标时段的时间长度为5秒。
可选地，终端获取终端在目标时段内的每个时间单元的接收信号强度。示例性地，终端获取终端在目标时段内的每一秒的接收信号强度。
可选地，终端每隔预设时间获取终端在一个目标时段内的接收信号强度。预设时间由终端预先设定，或者，由技术人员自定义设定。示例性地，预设时间为10秒。
步骤202，基于终端在目标时段内的接收信号强度，确定终端处于第一信号场景或第二信号场景。
第一信号场景对应的信号强度高于第二信号场景对应的信号强度。第一信号场景也称为强信号场景，第二信号场景也称为弱信号场景。终端基于其在目标时段内的接收信号强度来判断自身处于强信号场景或者弱信号场景。
步骤203，若终端处于第一信号场景，则基于终端在目标时段内的吞吐量，确定终端天线的工作模式。
吞吐量是指对网络、设备、端口、虚电路或其他设施，单位时间内成功地传送数据的数量。终端天线的工作模式包括SISO模式或MIMO模式。
在一种可能的实现方式中，当终端在目标时段内处于强信号场景，且吞吐量较大时，确定终端天线的工作模式为MIMO模式，使得终端的TRP和TIS得以提升，进而提升通信质量和通信距离。
在另一种可能的实现方式中，当终端在目标时段内处于强信号场景，且吞吐量较小时，确定终端天线的工作模式为SISO模式，由于吞吐量较小时对通信质量和通信距离的要求较低，此时切换至SISO模式，能有效节省终端功耗。
综上所述，本申请实施例提供的技术方案，通过在终端处于强信号场景时，基于终端的吞吐量来确定终端天线的工作模式，使得终端天线的工作模式能兼 顾通信质量与终端功耗两方面因素，在满足业务需求的前提下节省终端功耗。例如，当终端在目标时段内处于强信号场景且吞吐量较大时，确定终端天线使用MIMO模式，使得终端的TRP和TIS得以提升，进而提升通信质量和通信距离；再例如，当终端在目标时段内处于强信号场景且吞吐量较小时，确定终端天线使用SISO模式，能有效节省终端功耗。
在上文实施例中提到，终端根据自身在目标时段内的接收信号强度判断自身处于强信号场景或弱信号场景。下面对这一判断过程进行介绍。在基于图2所示实施例提供的可选实施例中，步骤202包括如下子步骤：
步骤202a，获取终端在目标时段内的接收信号强度的变化趋势。
变化趋势用于表征接收信号强度在一段时间内的变化情况。可选地，终端在目标时段内的接收信号强度的变化趋势包括变强趋势、变弱趋势和维持趋势。其中，变强趋势是指终端在目标时段内的接收信号强度整体呈现变强的趋势，变弱趋势是指终端在目标时段内的接收信号强度整体呈现变弱的趋势，维持趋势是指终端在目标时段内的接收信号强度整体保持稳定的趋势。
可选地，终端将目标时段内的最后一个时间单元的接收信号强度与第一个时间单元的接收信号强度进行比对，以确定终端在目标时段内的接收信号强度的变化趋势。
可选地，若最后一个时间单元的接收信号强度大于第一个时间单元的接收信号强度，则终端在目标时段内的接收信号强度的变化趋势为变强趋势；若最后一个时间单元的接收信号强度小于第一个时间单元的接收信号强度，则终端在目标时段内的接收信号强度的变化趋势为变弱趋势；若最后一个时间单元的接收信号强度等于第一个时间单元的接收信号强度，则终端在目标时段内的接收信号强度的变化趋势为维持趋势。
步骤202b，基于变化趋势、信号强度门限，确定终端处于第一信号场景或第二信号场景。
信号强度门限是一种预定义参数，采用RSSI_Thr来表示。示例性地，信号强度门限为-75dBm。
在一种可能的实现方式中，信号强度门限为固定值。在另一种可能的实现方式中，信号强度门限与终端所处的业务场景的时延要求呈负相关关系。也即，终端所处的业务场景的时延要求越高，也即终端所处的业务场景所要求的时延越小时，信号强度门限越大；终端所处的业务场景的时延要求越低，也即终端所处的业务场景所要求的时延越大时，则信号强度门限越小。
可选地，当信号强度门限基于终端所处的业务场景的时延要求确定时，终端保存有终端所处的业务场景、终端所处的业务场景的时延要求以及信号强度门限之间的第一对应关系，之后基于终端所处的业务场景查找上述第一对应关系，得到相应的信号强度门限，之后通过预定接口将该确定出的信号强度门限传递至无线通信芯片。或者，终端保存有终端所处的业务场景、终端所处的业务场景的时延要求之间的第二对应关系，以及终端所处的业务场景的时延要求 与信号强度门限之间的函数关系式。终端确定终端所处的业务场景后，查找第二对应关系得到终端所处的业务场景的时延要求，之后通过上述函数关系式得出相应的信号强度门限。
可选地，当变化趋势为变强趋势或维持趋势时，若终端在目标时段内的目标时间单元的接收信号强度大于或等于信号强度门限，则确定终端处于第一信号场景；当变化趋势为变强趋势或维持趋势时，若终端在目标时段内的目标时间单元的接收信号强度小于信号强度门限，则确定终端处于第二信号场景。其中，在考虑等于的情况下，可以将等于归于大于，即大于或等于，也可以将等于归于小于，即小于或等于，本申请对此不作限定。下文中再次出现此类情况时，以上述描述为准，本申请对此不再赘述。可选地，上述目标时间单元是指目标时段内的最后一个时间单元。由于目标时段内的最后一个时间单元的接收信号强度与当前时刻的接收信号强度较为接近，通过比对最后一个时间单元的接收信号强度与信号强度门限的大小关系，能直观反应当前时刻的接收信号强度的大小，后续确定工作模式时更加准确。
在其他可能的实现方式中，若终端在目标时段内的接收信号强度的平均值大于或等于信号强度门限，则确定终端处于第一信号场景；若终端在目标时段内的接收信号强度的平均值小于信号强度门限，则确定终端处于第二信号场景。
可选地，当变化趋势为变弱趋势时，若终端在目标时段内的目标时间单元的接收信号强度大于或等于信号强度门限，则确定终端处于第一信号场景；当变化趋势为变弱趋势时，若终端在目标时段内的目标时间单元的接收信号强度小于信号强度门限，则确定终端处于第二信号场景。可选地，目标时间单元是指目标时段内的最后一个时间单元。
可选地，步骤202b还实现为：基于变化趋势、信号强度门限以及信号强度余量，确定终端处于第一信号场景或第二信号场景。
信号强度余量也是一种预定义参数，采用C来表示。示例性地，信号强度余量为2dB。通过设置信号强度余量这一参数，避免终端天线在SISO模式与MIMO模式之间频繁切换。
可选地，当变化趋势为变强趋势或维持趋势，且终端在目标时段内的目标时间单元的接收信号强度大于或等于信号强度门限和信号强度余量之和，则确定终端处于第一信号场景。当变化趋势为变强趋势或维持趋势，且终端在目标时段内的目标时间单元的接收信号强度小于信号强度门限和信号强度余量之和，则确定终端处于第二信号场景。可选地，目标时间单元是目标时段内的最后一个时间单元。
终端将目标时段内的最后一个时间单元的接收信号强度与信号强度门限和信号强度余量之和做比较，若目标时段内的最后一个时间单元的接收信号强度大于或等于信号强度门限和信号强度余量之和，则确定终端处于强信号场景；若目标时段内的最后一个时间单元的接收信号强度小于信号强度门限和信号强度余量之和，则确定终端处于弱信号场景。示例性地，终端在目标时段内的最后一个时间单元的接收信号强度RSSI大于或等于RSSI_Thr+C时，终端处于强 信号场景；终端在目标时段内的最后一个时间单元接收信号强度RSSI小于RSSI_Thr+C时，终端处于弱信号场景。
可选地，若变化趋势为变弱趋势，且终端在目标时段内的目标时间单元的接收信号强度小于信号强度门限和信号强度余量之差，则确定终端处于第二信号场景；若变化趋势为变弱趋势，且终端在目标时段内的目标时间单元的接收信号强度大于或等于信号强度门限和信号强度余量之差，则确定终端处于第一信号场景。
终端将目标时段内的最后一个时间单元的接收信号强度与信号强度门限和信号强度余量之差做比较，若目标时段内的最后一个时间单元的接收信号强度小于信号强度门限和信号强度余量之差，则确定终端处于弱信号场景；若目标时段内的最后一个时间单元的接收信号强度大于或等于信号强度门限和信号强度余量之和，则确定终端处于强信号场景。示例性地，终端在目标时段内的接收信号强度RSSI大于或等于RSSI_Thr-C时，终端处于强信号场景；终端在目标时段内的接收信号强度RSSI小于RSSI_Thr-C时，终端处于弱信号场景。
本申请实施例提供的技术方案，通过变化趋势、信号强度门限和信号强度余量来判断终端天线处于强信号场景还是弱信号场景，通过信号强度门限初步判断信号的强弱，通过设置信号强度余量这一参数，避免终端天线在SISO模式与MIMO模式之间频繁切换。
图3示出了本申请一个实施例示出的终端天线的工作模式确定方法的流程图。在基于图2所示实施例提供的可选实施例中，步骤203替代实现为步骤203a和步骤203b。该方法包括：
步骤301，获取终端在目标时段内的接收信号强度。
步骤302，基于终端在目标时段内的接收信号强度，确定终端处于第一信号场景或第二信号场景。
第一信号场景对应的信号强度高于第二信号场景对应的信号强度。
步骤203a，若终端处于第一信号场景，基于终端在目标时段内的吞吐量，确定终端处于第一吞吐量场景或第二吞吐量场景。
第一吞吐量场景对应的吞吐量大于第二吞吐量场景对应的吞吐量。第一吞吐量场景也即是高吞吐量场景，第二吞吐量场景也即是低吞吐量场景。
可选地，终端获取终端在目标时段内的吞吐量的平均值；若终端在目标时段内的吞吐量的平均值大于吞吐量门限，则确定终端处于第一吞吐量场景；若终端在目标时段内的吞吐量的平均值小于吞吐量门限，则确定终端处于第二吞吐量场景。吞吐量门限是一种预定义参数，采用T-PUT_Thr来表示。示例性地，吞吐量门限为30Mps/s。吞量门限值用于区分第一吞吐量场景和第二吞吐量场景。
可选地，终端获取终端在目标时段内的吞吐量的最大值；若终端在目标时段内的吞吐量的最大值大于吞吐量门限，则确定终端处于第一吞吐量场景；若终端在目标时段内的吞吐量的最大值小于吞吐量门限，则确定终端处于第二吞 吐量场景。
步骤203b，基于终端处于第一吞吐量场景或第二吞吐量场景，确定终端天线的工作模式。
若终端处于第一吞吐量场景，则确定终端天线的工作模式为MIMO模式。当终端处于第一吞吐量场景时，若终端天线的当前工作模式为MIMO模式，则终端天线的工作模式保持不变；若终端天线的当前工作模式为SISO模式，则控制终端天线的工作模式由SISO模式切换至MIMO模式。
若终端处于第二吞吐量场景，则确定终端天线的工作模式为SISO模式。当终端处于第二吞吐量场景时，若终端天线的当前工作模式为SISO模式，则终端天线的工作模式保持不变；若终端天线的当前工作模式为MIMO模式，则控制终端天线的工作模式由MIMO模式切换至SISO模式。
当终端处于强信号且低吞吐量场景时，终端天线的工作模式为SISO模式即可满足业务需求，此时确定终端天线的工作模式为SISO模式，节省终端的功耗。当终端处于强信号且高吞吐量场景时，终端天线的工作模式为SISO模式通常不满足业务需求，此时确定终端天线的工作模式为MIMO模式，提升通信质量以及通信距离。
步骤305，若终端处于第二信号场景，则确定终端天线的工作模式为MIMO模式。
终端处于弱信号场景时，为弥补弱信号所造成的通信质量下降、通信距离缩短等问题，无论吞吐量高或低，终端均采用MIMO模式，以提升通信质量和通信距离。
当终端处于第二信号场景时，若终端天线的工作模式为MIMO模式，则终端天线的工作模式保持不变。若终端天线的工作模式为SISO模式，则终端天线的工作模式切换至MIMO模式。
在一个示例中，设定RSSI_thr＝-75dBm，T-PUT_thr＝30Mbps/s，C＝2dB，T0＝10秒、T1、T2＝5秒。终端检测到前5秒的RSSI分别为-74dBm、-72dBm、-73dBm、-70dBm、-70dBm，确定信号强度变化趋势为变强趋势；由于-70>-75+2，认为终端当前处于强信号场景；之后检测到前5秒的吞吐量分别为，15Mbps/s、18Mbps/s、20Mbps/s、22Mbps/s、16Mbps/s，平均值为18.2Mbps/s，小于30Mbps/s，认为终端当前处于低吞吐量场景。终端当前处于强信号+低吞吐量场景，此时SISO模式完全能满足用户需求。若是当前为MIMO模式，则可切到SISO模式，来降低功耗。终端在等待10s后可进行下一轮检测。
综上所述，本申请实施例提供的技术方案，通过在终端在目标时段内处于强信号场景，且吞吐量较大时，确定终端天线使用MIMO模式，使得终端的TRP和TIS得以提升，进而提升通信质量和通信距离；当终端在目标时段内处于强信号场景，且吞吐量较小时，确定终端天线使用SISO模式，能有效节省终端功耗；当终端在目标时段内处于弱信号场景时，为弥补弱信号所造成的通信质量下降、通信距离缩短等问题，无论吞吐量高或低，终端均采用MIMO模式，以提升通信质量和通信距离。
