Description

屏下天线的管理方法及装置
本申请要求于2020年11月16日提交国家知识产权局、申请号为202011281057.5、申请名称为“屏下天线的管理方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种屏下天线的管理方法及装置。
背景技术
随着消费电子市场的蓬勃发展，具备屏幕显示功能的电子设备广泛出现在我们的日常生活中，例如智能手机、平板电脑、智能手表等。随着移动互联网应用(例如短视频、在线游戏)的普及，对这类电子设备需要支持的无线通信能力(例如，天线性能)也提出了更高的要求。而物体的遮挡会影响到电磁信号/光信号的正常传播，降低天线的辐射效率，导致通信链路对应的信干噪比(signal-to-interference-and-noise ratio，SINR)降低，进而影响到通信质量。天线的辐射效率的衰减程度与遮挡物的材质有关。例如，当遮挡物是金属材质时，它对电磁信号的衰减就更强，当遮挡物是非透光材质时，它对光信号的衰减就更大。
具备屏幕显示功能的电子设备通常支持屏幕触摸操作和无线通信的功能。这类电子设备的演进趋势是在不增加产品整体尺寸大小，甚至进一步小型化的情况下，屏幕却越做越大，屏占比也越做越高。因此，目前拟采用屏下天线(Antenna-under-Display)技术优化天线性能。屏下天线也可以称为屏内天线(Antenna-on-Display)。图1为一种屏下天线的示意图，通过将天线安装在屏幕的下方，利用屏幕通常采用玻璃、树脂等非金属材质，对电磁信号/光信号的吸收率小于金属材质外壳的技术特性，提高天线的辐射效率。但是仅仅考虑电子设备本身对电磁信号/光信号的遮挡，只能对天线的辐射效率进行一部分提升。

具体实施方式
在本申请的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。在本申请的描述中，除非另有说明，“至少一个”是指一个或多个，“多个”是指两个或多于两个。
另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
本申请实施例的技术方案可以应用于第四代(4th Generation，4G)系统、基于4G系统演进的各种系统、第五代(5th Generation，5G)系统、基于5G系统演进的各种系统中。其中，4G系统也可以称为演进分组系统(evolved packet system，EPS)。4G系统的核心网可以称为演进分组核心网(evolved packet core，EPC)，接入网可以称为长期演进(long term evolution，LTE)。5G系统的核心网可以称为5GC(5G core)，接入网可以称为新无线(new radio，NR)。本申请实施例的技术方案适用于同构网络也适用于异构网络，适用于频分双工(frequency-division duplex，FDD)系统也适用于时分双工(time-division duplex，TDD)系统，适用于低频通信场景也适用于高频通信场景。
本申请提供的技术方案所适用的通信系统中可以包括至少一个网络设备和至少一个终端。至少一个终端中的一个或多个终端可以和至少一个网络设备中的一个或多个网络设备通信。示例性的，参见图2，一个终端(例如，终端1)可以和一个网络设备(例如，网络设备1)通信，也可以和多个网络设备(例如，网络设备1和网络设备2)通信。一个终端(例如，终端1)还可以和其他终端(例如，终端2)通信。
网络设备为网络侧的一种用于发送信号，或者，接收信号，或者，发送信号和接收信号的实体。网络设备可以为部署在无线接入网(radio access network，RAN)中为终端提供无线通信功能的装置，例如，可以为传输接收点(transmission reception point，TRP)、基站、各种形式的控制节点(例如，网络控制器、无线控制器(例如，云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器))等。具体的，网络设备可以为各种形式的宏基站，微基站(也称为小站)，中继站，接入点(access point，AP)、卫星等，也可以为基站的天线面板，远程射频头(remote radio head，RRH)等。所述控制节点可以连接多个基站，并为所述多个基站覆盖下的多个终端配置资源。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同。例如，LTE系统中可以称为演进型基站(evolved NodeB，eNB或eNodeB)，5G系统或NR系统中可以称为下一代基站节点(next generation node base station，gNB)，本申请对基站的具体名称不作限定。网络设备还可以是未来演进的公共陆地移动网络(public land mobile network，PLMN)中的网络设备等。
终端是用户侧的一种用于接收信号，或者，发送信号，或者，接收信号和发送信 号的实体，一种支持屏幕触摸操作的无线通信设备。终端用于向用户提供语音服务和数据连通性服务中的一种或多种。终端还可以称为用户设备(user equipment，UE)、终端设备、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。终端可以是智能手机、平板电脑、智能手表、移动站(mobile station，MS)、用户单元(subscriber unit)、无人机、物联网(internet ofthings，IoT)设备、无线局域网(wireless local area networks，WLAN)中的站点(station，ST)、蜂窝电话(cellular phone)、智能电话(smart phone)、无绳电话、无线数据卡、平板型电脑、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)设备、膝上型电脑(laptop computer)、机器类型通信(machine type communication，MTC)终端、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备(也可以称为穿戴式智能设备)。终端还可以为下一代通信系统中的终端，例如，5G系统中的终端或者未来演进的PLMN中的终端等。
终端的屏下天线性能除了会受到屏幕的阻挡的影响之外，在实际使用过程中，还会受到用户操作、周围环境等带来的遮挡的影响，这对于屏下天线性能的影响也非常大。例如，参见图3，用户使用平板电脑进行在线游戏操作，通过不断触摸屏幕不同位置进行游戏互动。在某一时刻，部分屏下天线被手掌遮挡。如果不考虑这种用户操作带来的遮挡，屏下天线的辐射效率将受到削弱，严重时SINR不满足通信要求，可能会造成通信失败。另外，相同物体的遮挡对高频信号(例如，毫米波信号、亚毫米波信号)的影响比厘米波信号影响更大，而光通信受到光线明暗的影响很大，所以高频通信场景(例如，毫米波通信场景，亚毫米波通信场景)和光通信场景对物体的遮挡更敏感。因此，这个问题在高频通信场景和光通信场景会尤为突出。
为了解决该问题，本申请提供了一种屏下天线的管理方法，在信号传输之前，根据屏下天线的遮挡情况，确定适合用于信号传输的天线集合，采用该天线集合进行信号传输，从而提升天线的辐射效率。参见图4，该方法包括：
401、获取设备的屏下天线遮挡信息。
本申请中的设备可以为终端，也可以为其他具备屏幕显示功能的无线通信设备。该设备(例如，终端)可以与网络设备或其他设备(例如，另一个终端)通信。本申请实施例的执行主体可以为该设备，也可以为与该设备具有有线或无线连接的其他设备，本申请不作限制。
在一种情况下，本申请中的天线为天线阵子。在另一种情况下，本申请中的天线为天线阵列。一个天线阵列可以包括一个或多个天线子阵列，一个天线子阵列可以包括一个或多个天线阵子。也就是说，一个天线阵列可以包括多个天线阵子。天线阵子也可以称为天线阵元或辐射单元。
其中，屏下天线遮挡信息用于确定设备的屏下天线是否被遮挡。
402、根据屏下天线遮挡信息确定第一天线集合，第一天线集合为第二天线集合的子集，第二天线集合由设备的未被遮挡的屏下天线组成。
其中，第一天线集合可以为第二天线集合的真子集，第一天线集合也可以和第二 天线集合相同。
403、采用第一天线集合进行信号传输。
其中，信号传输包括信号发送和/或信号接收。
步骤403在具体实现时，可以采用第一天线集合进行不同传输模式的信号传输。例如，可以采用单输入单输出(single input single output，SISO)、多输入多输出(Multiple Input Multiple Output，MIMO)、波束赋形(beamforming)等传输模式进行信号传输。
其中，SISO传输模式是指在发送端和接收端同时采用一个天线进行信号传输的传输模式。MIMO传输模式是指在发送端和接收端同时采用多个天线进行信号传输的传输模式。MIMO利用多个发送天线和多个接收天线产生多个空间传输通道，从而使得信号可以在多个空间传输通道中并行传输，更好的利用空间维度的资源，提高频谱效率。波束赋形通过调整天线的加权系数产生具有指向性的波束，可以提高波束增益和信号传输增益。
本申请实施例提供的方法，可以根据屏下天线遮挡信息，选择未被遮挡的天线中的一个或多个进行信号传输，避免由于用户操作、周围环境等遮挡屏幕从而使得屏下天线的辐射效率降低，提高通信链路的信干噪比，减少无效传输、重复传输的次数，降低设备的发送功率和功耗，提高通信服务质量。
可选的，步骤401在具体实现时包括：401-1、获取设备的屏幕遮挡信息，根据屏幕遮挡信息确定屏下天线遮挡信息。
步骤401-1在具体实现时可以包括：
11)确定设备的屏幕的被遮挡区域。
12)确定设备的屏幕的被遮挡区域下的屏下天线为被遮挡的屏下天线，或者，在屏下天线为屏下天线阵列、且设备的屏幕的被遮挡区域下的天线阵子的个数与设备的屏幕的被遮挡区域下的天线阵子所属的天线阵列中的天线阵子个数的比值大于第一阈值的情况下，确定设备的屏幕的被遮挡区域下的屏下天线为被遮挡的屏下天线。
步骤11)可以通过以下方式1或方式2或方式3实现。
方式1、根据设备的屏幕的被触摸的区域确定被遮挡区域。
方式1为一种接触式(即需要遮挡物与屏幕接触)获取设备的屏幕的被遮挡区域的方式。方式1在具体实现时，可以确定设备的屏幕的被触摸的区域为被遮挡区域，也可以确定包含设备的屏幕的被触摸的区域的一个区域为被触摸的区域，例如，考虑到人的手指指腹有一定弧度，手指指腹与设备屏幕接触时，手指其他部分(例如，指甲部分)距离屏幕也是比较近的，对屏下天线也会产生遮挡，因此，可以以设备的屏幕的被触摸的区域为基础向外扩展一部分区域后得到的区域作为被遮挡区域，例如，参见图5，可以将设备的屏幕的被触摸的区域的边缘向外扩展一定的宽度，例如，扩展3毫米(mm)，将扩展后的区域作为被遮挡区域。具体的扩展方式可以通过算法实现。
方式1可以通过机械式，或者，通过电磁式或光学式的方式实现，以下通过方式1.1(方式1通过机械式的方式实现)和方式1.2(方式1通过电磁式或光学式的方式实现)分别进行描述。
方式1.1、方式1通过机械式方式实现。
在方式1.1下，一种可能的实现方式，可以获取设备的屏幕中的区域的电容变化信息，确定电容发生变化的区域为被触摸的区域。该情况下，方式1的一种可替换的描述为：获取设备的屏幕中的区域的电容变化信息，根据电容发生变化的区域确定被遮挡区域。具体可以获取设备的屏幕中的区域的电容变化信息，确定电容发生变化的区域为设备的屏幕的被触摸的区域，根据被触摸的区域确定被遮挡区域。
示例性的，参见图6，设备的屏幕由表(设备的屏幕表面)及里分别为：前介质层、电容层、显示层、天线层、后介质层。其中，前介质层例如可以为玻璃、树脂等，电容层集成一层电容材料，例如，超声薄膜传感材料，具体可以为超声薄膜传感器(例如，薄膜晶体管(thin film transistor，TFT))，显示层例如可以为有机发光二极管(organic light-emitting diode，OLED)、液晶显示器(liquid crystal display，LCD)等，天线层包括天线、射频(radio frequency，RF)、印制电路板(printed circuit board，PCB)板等，后介质层例如可以为金属。天线离散分布在天线层所在的平面内。当用户触摸屏幕时，会改变屏幕的压力，进而引起电容层的电容特性的变化，根据该特性可以判断屏幕的哪些区域被触摸。该方法可以充分利用设备的屏幕本身的特性方便快捷地确定屏幕的哪些区域被遮挡。
在方式1.1下，另一种可能的实现方式，设备的屏幕下可以放置压力传感器，此时，可以获取设备的屏幕中的区域的压力变化信息，确定压力发生变化的区域为被触摸的区域。该情况下，方式1的一种可替换的描述为：获取设备的屏幕中的区域的压力变化信息，根据压力发生变化的区域确定被遮挡区域。具体可以获取设备的屏幕中的区域的压力变化信息，确定压力发生变化的区域为设备的屏幕的被触摸的区域，根据被触摸的区域确定被遮挡区域。
方式1.2、方式1通过电磁式或光学式的方式实现。
在方式1.2下，可以通过一个或多个传感器确定设备的屏幕的被触摸的区域。该情况下，方式1的一种可替换的描述为：采用一个或多个传感器对设备的屏幕进行遮挡检测，得到检测结果；根据检测结果确定被遮挡区域。具体可以通过一个或多个传感器确定设备的屏幕的被触摸的区域，根据被触摸的区域确定被遮挡区域。
其中，传感器可以位于设备的屏幕下方(例如，图7中的传感器1至传感器4)，也可以位于设备的边框下方(例如，图7中的传感器5和传感器6)。传感器可以为电磁传感器(例如，测距传感器)、光学传感器(例如，红外探测器、飞秒激光器(time of flight，ToF))等。
方式1.2下，传感器可以通过主动方式检测被遮挡区域，也可以通过被动方式检测被遮挡区域。主动方式是指传感器发送信号(例如，电磁信号，光信号(例如，非可见光))，再进行检测的方式。被动方式是指传感器不发送信号，直接进行检测的方式。
在采用主动方式检测时，信号检测有两种方式。第一种方式，参见图8中的(a)，可以一个传感器(例如，传感器A)发送信号，另一个传感器(例如，传感器B)接收经过遮挡物反射的信号。另一种实现方式，参见图8中的(b)，一个传感器(例如，传感器B)发送信号后，再接收经过遮挡物反射的信号。针对电磁传感器，该信号可 以为电磁信号，针对光学传感器，该信号可以为光信号。可以理解的是，第一种方式至少需要2个传感器。
通过进行信号检测确定设备的屏幕的被触摸的区域的实现方式可以为以下实现方式中的任意一种。
实现方式1、通过经过遮挡物反射的信号的强度确定设备的屏幕上哪些区域被触摸。
其中，由于信号传输的距离越长，信号的衰减越大，因此，经过遮挡物反射的信号的强度可以表征信号的传输距离，从而可以根据经过遮挡物反射的信号的强度确定设备的屏幕上哪些区域被触摸。
示例性的，针对屏幕上的某个位置(例如，位置A)，在用户触摸位置A时，传感器A的发送信号相比传感器B的接收信号衰减3分贝(Decibel，dB)的情况下，若传感器A的发送信号的强度为8dB，传感器B的接收信号的强度为3dB，则说明信号衰减了5dB，此时认为位置A未被触摸。其中，用户触摸位置A时，传感器A的发送信号相比传感器B的接收信号衰减大小可以是用户触摸位置A时测试得到的，也可以是根据其他位置(例如，位置B)的信号衰减大小以及位置B与位置A之间的几何关系计算出来的，本申请不作限制。
实现方式2、采用传感器检测发送信号和接收信号的相位差，根据发送信号和接收信号的相位差计算得到信号的发送时刻和信号的接收时刻之间的时间差，进而确定信号传输的距离，根据该距离确定设备的屏幕上哪些区域被触摸。
其中，相位差Δη＝2*π*c*Δt/λ，c是指光速，Δt是指信号的发送时刻和信号的接收时刻之间的时间差，λ是指波长，“*”是指“乘以”。则根据Δη可以计算得到Δt，Δt*c即信号的传输距离。
由于设备的屏幕上的不同的位置被触摸时，信号的传输距离不同，因此，可以根据信号的传输距离确定设备的屏幕上哪些区域被触摸。示例性的，参见图9，在用户触摸位置A时，信号的实际传输距离为20mm的情况下，若根据传感器检测到的Δη计算得到的传输距离为22mm，则说明位置A未被触摸。其中，用户触摸位置A时，信号的实际传输距离可以是用户触摸位置A时测试得到的，也可以是根据其他位置(例如，位置B)的信号的实际传输距离以及位置B与位置A之间的几何关系计算出来的，本申请不作限制。
根据实现方式2确定信号的传输距离的方法，准确性较高。
实现方式3、采用传感器检测信号的发送时刻和信号的接收时刻之间的时间差，进而确定信号的传输距离，根据该距离确定设备的屏幕上哪些区域被触摸。
其中，用于检测时间差的传感器可以为ToF。确定时间差之后的实现过程可参见实现方式2，不再赘述。
在采用被动方式检测被遮挡区域的情况下，若光学传感器从某个位置接收的光信号出现信号中断，则判断该位置被遮挡。上述光信号可以是自然光的一种或者多种频率分量，比如红外光或者近紫外光，或者是可见光信号。
方式2、根据遮挡设备的屏幕的遮挡物在第一空间内的位置确定设备的屏幕的被 遮挡区域，第一空间的底面在水平面上的投影为设备的屏幕表面，高度为预设值(记为第一预设值)。
一种情况下，参见图10中的(a)，第一空间的底面为设备的屏幕表面。另一种情况下，参见图10中的(b)，第一空间的底面为与设备的屏幕表面距离为第二预设值的平面。
第一预设值和/或第二预设值可以为预先设置的。例如，第一预设值可以为30mm，第二预设值可以为1mm。第一预设值和/或第二预设值也可以与设备的尺寸、设备的屏幕的尺寸、设备的通信模块的发送功率、设备的通信模块的接收功率、采用第一天线集合传输的信号承载的通信业务类型、通信过程中设备执行的业务的触屏频度、设备对屏下天线遮挡信息的检测能力中的一个或多个有关。例如，设备的尺寸越大时，第一预设值和/或第二预设值可以越大，其中，第一预设值可以小于设备的尺寸。设备的屏幕的尺寸越大时，第一预设值和/或第二预设值可以越大，其中，第一预设值可以小于设备的屏幕的尺寸。设备的通信模块的发送功率越大时，第一预设值和/或第二预设值可以越小。设备的通信模块的接收功率越大时，第一预设值和/或第二预设值可以越小。采用第一天线集合传输的信号承载的通信业务类型对应的功率越低时，第一预设值和/或第二预设值可以越大(例如，无线保真(wireless fidelity，WiFi)通信、近场通信时第一预设值和/或第二预设值可以比蜂窝通信时大)。通信过程中设备执行的业务的触屏频度越高，第一预设值和/或第二预设值可以越小。例如，实时互动业务对应的第一预设值和/或第二预设值可以比仅触摸按键操作的业务低。设备对屏下天线遮挡信息的检测能力越弱，例如，执行检测的传感器或检测模块的处理能力越弱，第一预设值和/或第二预设值可以越小。
方式2为一种非接触式(即不需要遮挡物与屏幕接触)获取设备的屏幕的被遮挡区域的方式。
在方式2通过电磁式或光学式方式实现时，该情况下，方式2的一种可替换的描述为：采用一个或多个传感器对第一空间进行遮挡检测；根据遮挡设备的屏幕的遮挡物在第一空间中所处的位置投影到屏幕上的区域确定被遮挡区域。具体的，可以确定遮挡设备的屏幕的遮挡物在第一空间中所处的位置投影到屏幕上的区域为被遮挡区域，也可以确定以遮挡设备的屏幕的遮挡物在第一空间中所处的位置投影到屏幕上的区域为基础向外扩展一部分区域后得到的区域为被遮挡区域，具体实现与方式1中类似，可参考进行理解不再赘述。
其中，关于传感器以及传感器的检测原理的描述可参见上文，不再赘述。区别在于，方式1中传感器用于检测设备的屏幕的哪些区域被触摸，此处传感器用于检测遮挡物在第一空间中所处的位置。
在方式2中，在利用传感器的接收信号的强度判断某个被遮挡的区域下的屏下天线是否被遮挡的情况下，将遮挡该区域的遮挡物反射的信号(即传感器的接收信号)的强度记为α，当α>Thr1，认为该屏下天线被遮挡，当Thr2＜α≤Thr1，由于遮挡物距离设备的屏幕较远，在某些情况下(例如，通信质量要求较高或设备的发射功率较小的情况下)可以认为该屏下天线被遮挡，这里Thr1和Thr2均为信号强度的门限值。在利用信号的传输距离判断某个被遮挡的区域下的屏下天线是否被遮挡的情况下，将 信号的传输距离记为β，当β＜Thr3，认为该屏下天线被遮挡，当Thr3≤β＜Thr4，由于遮挡物距离设备的屏幕较远，在某些情况下(例如，通信质量要求较高或设备的发射功率较小的情况下)可以认为该屏下天线被遮挡，这里Thr3和Thr4均为信号的传输距离的门限值。该部分对于屏下天线是否被遮挡的判决结果不是绝对的遮挡或未被遮挡，这种判决可以称为软判决，本申请其他部分中对于屏下天线是否被遮挡的判决结果要么为遮挡，要么为未被遮挡的判决可以称为硬判决。
方式3、根据第一平面的被触摸的区域确定被遮挡区域，第一平面在水平面上的投影为设备的屏幕表面，第一平面距离设备的屏幕的高度为第三预设值(具体可参见图11进行理解)。
方式3中确定被遮挡区域的过程与方式1中确定被遮挡区域的过程类似，将方式1中的设备的屏幕当作第一平面进行理解即可。区别在于，由于遮挡物在触摸第一平面时无法产生对屏幕的压力，因此，此处无法采用方式1中的方式1.1确定被遮挡区域。
步骤12)中包括了确定被遮挡的屏下天线的两种方式，一种方式是直接确定设备的屏幕的被遮挡区域下的屏下天线为被遮挡的屏下天线。示例性的，参见图12，图12中天线可以为天线阵子也可以为天线阵列，该情况下，可以将图12中虚线圈出的天线确定为被遮挡的屏下天线。另一种方式是在屏下天线为屏下天线阵列、且设备的屏幕的被遮挡区域下的天线阵子的个数与设备的屏幕的被遮挡区域下的天线阵子所属的天线阵列中的天线阵子个数的比值大于第一阈值的情况下，确定设备的屏幕的被遮挡区域下的屏下天线为被遮挡的屏下天线。示例性的，参见图13，图13中天线为天线阵列，每个天线阵列包括4个天线阵子，若第一阈值为0.5，则在图13中，虚线圈出的天线确定为被遮挡的屏下天线。
上述步骤401在具体实现时，可以对设备的屏幕进行区域划分(记为情况1)或对第一空间进行空间划分(记为情况2)或对第一平面进行区域划分(记为情况3)，并根据划分的区域或空间确定被遮挡的屏下天线。以下对情况1、情况2和情况3下本申请实施例提供的方法进行示例性说明。
情况1、对设备的屏幕进行区域划分。
在情况1下，设备的屏幕由多个第一区域组成，第一区域与屏下天线具有对应关系。例如，参见图14，设备的屏幕被分为45个第一区域，编号分别为1，2，3，…，45，12个屏下天线，编号分别为a，b，c，…，l，建立屏下天线和第一区域的对应关系，例如，图14中屏下天线和第一区域的对应关系可参见表1。
表1
第一区域 天线
6 a
8 b
10 c
16 d
18 e
20 f
26 g
28 h
30 i
36 j
38 k
40 l
需要说明的是，图14中以一个第一区域对应一个屏下天线为例进行绘制，实际上，一个第一区域可以对应多个屏下天线，也可以多个第一区域对应一个屏下天线。
在情况1下，步骤401在具体实现时可以包括：当第一屏下天线对应的第一区域的被遮挡比例大于第二阈值，确定第一屏下天线被遮挡；当第一屏下天线对应的第一区域的被遮挡比例小于第二阈值，确定第一屏下天线未被遮挡；其中，第一屏下天线为设备的屏下天线中的一个。第一屏下天线对应的第一区域的被遮挡比例等于第二阈值时，可以确定第一屏下天线被遮挡，也可以确定第一屏下天线未被遮挡。
该情况下，若某个/某些第一区域的被遮挡比例大于第二阈值，则某个/某些第一区域下的天线被遮挡。例如，基于表1所示的示例，若第一区域6的被遮挡比例大于第二阈值，则可以确定天线a被遮挡。若第一区域6和第一区域10的被遮挡比例大于第二阈值，则可以确定天线a和天线c被遮挡。
在情况1下，第一屏下天线对应的第一区域的被遮挡区域可以通过上述方式1中的机械式或电磁式或光学式的方式进行检测，具体可参见上文，不再赘述。若采用电磁式或光学式的方式进行检测，可以每个第一区域下放置一个或多个传感器来检测该第一区域下的屏下天线是否被遮挡，也可以多个第一区域下放置一个或多个传感器来检测该多个第一区域下的屏下天线是否被遮挡，本申请不作限制。
情况2、对第一空间进行空间划分。
在情况2下，第一空间由M*N个子空间组成，M为大于1的整数，N为大于0的整数，第一空间的底面由M个第二区域组成，第二区域与屏下天线具有对应关系(与情况1中的第一区域和屏下天线的对应关系类似，可参照进行理解)，第二区域为底面、且高度为第一预设值的空间由N个子空间组成，对应同一个第二区域的N个子空间的高度可以相同也可以不同，本申请不作限制。例如，以第一空间的底面为设备的屏幕为例，参见图15，若第一预设值为20mm，M为6，N为2，则设备的屏幕被分为6个第二区域，每个第二区域为底面、且高度为20mm的空间由2个子空间组成，则第一空间由12个子空间组成，屏下天线和第二区域具有对应关系(图15中未示出)。
在情况2下，在第一种实现方式中，步骤401在具体实现时可以包括：
当第一子空间内遮挡设备的屏幕的遮挡物投影到屏幕上的面积与第一屏下天线对应的第二区域的面积之比大于第三阈值，确定第一屏下天线被遮挡；
当第一子空间内遮挡设备的屏幕的遮挡物投影到屏幕上的面积与第一屏下天线对应的第二区域的面积之比小于第三阈值，确定第一屏下天线未被遮挡。
其中，第一子空间为第一屏下天线对应的第二区域对应的N个子空间中的、被遮挡物占据的子空间中的距离设备的屏幕最近的子空间，第一屏下天线为设备的屏下天线中的一个，第三阈值与第一子空间对应。当第一子空间内遮挡设备的屏幕的遮挡物 投影到屏幕上的面积与第一屏下天线对应的第二区域的面积之比等于第三阈值时，可以确定第一屏下天线被遮挡，也可以确定第一屏下天线未被遮挡。
可以理解的是，第一屏下天线对应的第二区域对应的N个子空间中的、被遮挡物占据的子空间可能有多个，其中，距离设备的屏幕最近的子空间(也就是第一子空间)中的遮挡物对屏幕的遮挡最严重，因此，只需要判断第一子空间中的遮挡设备的屏幕的遮挡物投影到屏幕上的面积与第一屏下天线对应的第二区域的面积之比是否大于第三阈值即可。在确定第一子空间中的遮挡设备的屏幕的遮挡物投影到屏幕上的面积与第一屏下天线对应的第二区域的面积之比是否大于第三阈值后，确定第一屏下天线是否被遮挡的过程与情况1中类似，可参考进行理解，不再赘述。该情况下，可以在每个第二区域投影到屏幕上的区域下放置一个或多个传感器来检测该第二区域对应的屏下天线是否被遮挡，也可以在多个第二区域投影到屏幕上的区域下放置一个或多个传感器来检测该多个第二区域对应的屏下天线是否被遮挡，本申请不作限制。
其中，第一子空间内遮挡设备的屏幕的遮挡物投影到屏幕上的面积可以通过传感器进行检测，检测原理可参见上文中的方式2，不再赘述。
其中，第一子空间与第三阈值对应，其他子空间可以与其他阈值对应，判断其他子空间对应的屏下天线是否被遮挡的过程与第一子空间类似，不再赘述。不同的子空间对应的阈值可以相同也可以不同，本申请不作限制。一种可能的实现方式，与设备的屏幕距离相同的一层子空间对应的阈值可以相同，与设备的屏幕距离不同的子空间对应的阈值可以不同，由于距离设备的屏幕越远，对屏下天线的影响越小，因此，距离设备的屏幕越远的子空间对应的阈值可以越大。
在情况2下，在第二种实现方式中，N＝1，步骤401在具体实现时可以包括：
当用于检测第二区域(假设为第二区域1)对应的屏下天线是否被遮挡的传感器，接收到的经过第二区域1对应的第一子空间内的遮挡设备的屏幕的遮挡物反射的信号的强度大于第四阈值时，确定第二区域1对应的屏下天线被遮挡；
当用于检测第二区域1对应的屏下天线是否被遮挡的传感器，接收到的经过第二区域1对应的第一子空间内的遮挡设备的屏幕的遮挡物反射的信号的强度大于第五阈值小于或等于第四阈值时，在必要的情况下(例如，通信质量要求较高或设备的发射功率较小的情况下)，可以确定第二区域1对应的屏下天线被遮挡。也就是说，在通信质量要求较高或设备的发射功率较小的情况下，不采用第二区域1对应的屏下天线进行信号传输，避免由于该屏下天线被遮挡从而降低通信质量或提高设备的发射功率。
将用于检测第二区域1对应的屏下天线是否被遮挡的传感器，接收到的经过第二区域1对应的第一子空间内的遮挡设备的屏幕的遮挡物反射的信号的强度记为α，第四阈值记为Thr1，第五阈值记为Thr2。也就是说，当α>Thr1，由于遮挡物距离设备的屏幕较近，认为第二区域1对应的屏下天线被遮挡，当Thr2＜α≤Thr1，由于遮挡物距离设备的屏幕较远，在某些情况下可以认为第二区域1对应的屏下天线被遮挡。该部分对于屏下天线是否被遮挡的判决结果不是绝对的遮挡或未被遮挡，这种判决可以称为软判决，本申请其他部分中对于屏下天线是否被遮挡的判决结果要么为遮挡，要么为未被遮挡的判决可以称为硬判决。
在情况2下，在第三种实现方式中，N＝1，步骤401在具体实现时可以包括：
当根据用于检测第二区域(假设为第二区域2)对应的屏下天线是否被遮挡的传感器(记为第一传感器)的检测结果确定的信号的传输距离小于第六阈值时，确定第二区域2对应的屏下天线被遮挡。
当根据第一传感器的检测结果确定的信号的传输距离大于或等于第六阈值小于第七阈值时，在必要的情况下(例如，通信质量要求较高或设备的发射功率较小的情况下)，可以确定第二区域2对应的屏下天线被遮挡。也就是说，在通信质量要求较高或设备的发射功率较小的情况下，不采用第二区域2对应的屏下天线进行信号传输，避免由于该屏下天线被遮挡从而降低通信质量或提高设备的发射功率。
将根据第一传感器的检测结果确定的信号的传输距离记为β，第六阈值记为Thr3，第七阈值记为Thr4。也就是说，当β＜Thr3，认为该屏下天线被遮挡，当Thr3≤β＜Thr4，由于遮挡物距离设备的屏幕较远，在某些情况下(例如，通信质量要求较高或设备的发射功率较小的情况下)可以认为该屏下天线被遮挡。该部分对于屏下天线是否被遮挡的判决结果不是绝对的遮挡或未被遮挡，这种判决可以称为软判决，本申请其他部分中对于屏下天线是否被遮挡的判决结果要么为遮挡，要么为未被遮挡的判决可以称为硬判决。
在上述实施例中，在一种情况下，Thr2＜α≤Thr1也可以替换为Thr2≤α≤Thr1。在另一种情况下，α>Thr1可以替换为α≥Thr1，此时，Thr2＜α≤Thr1也可以替换为Thr2≤α＜Thr1或Thr2＜α＜Thr1。类似的，在一种情况下，Thr3≤β＜Thr4可以替换为Thr3≤β≤Thr4。在另一种情况下，β＜Thr3可以替换为β≤Thr3，此时，Thr3≤β＜Thr4可以替换为Thr3＜β≤Thr4或Thr3＜β＜Thr4。
上述实施例中，第一阈值、第二阈值、第三阈值、第四阈值、第五阈值、第六阈值和第七阈值均可以为预先设置的。
情况3、对第一平面进行区域划分。
在情况3下，第一平面由多个第三区域组成，第三区域与屏下天线具有对应关系(与情况3中的第一区域和屏下天线的对应关系类似，可参照进行理解)。关于第一平面的描述可参见上文，不再赘述。情况3下确定被遮挡的屏下天线的过程与情况1类似，将情况1中的设备的屏幕替换为第一平面进行理解即可。情况3下确定被遮挡区域的过程可参见方式3的相关描述，不再赘述。
上述方式2、方式3、情况2和情况3下，不需要遮挡物接触设备的屏幕，因此，可以对未接触，但是近距离悬空的遮挡物是否遮挡屏幕进行判断，比如手掌或者手臂部分，可以更加准确的判断哪些屏下天线被遮挡。
可选的，步骤402在具体实现时包括：根据屏下天线遮挡信息确定第二天线集合；在第二天线集合中确定第一天线集合。
在确定第一天线集合时，可以根据传输模式确定第一天线集合中的天线个数。例如，若传输模式为SISO，则在第二天线集合中选择一个天线作为第一天线集合即可。若传输模式为4*4(其中，“*”之前表示发送天线个数，“*”之后表示接收天线个数)的MIMO，则在第二天线集合中选择4个天线作为第一天线集合。若传输模式为波束赋形，则根据波束赋形所需的天线个数，在第二天线集合中选择相应个数的天线作为第一天线集合即可。其中，为了方便信号传输，第一天线集合的天线可以为具有相同极 化方向的天线。
需要说明的是，当第二天线集合中的天线个数小于传输模式所需的天线个数时，可以结束本次通信，或者，继续本次通信但降低天线的使用数量。例如，若传输模式为4*4的MIMO，但第二天线集合中的天线个数为2，则可以将传输模式切换为2*2的MIMO。
可选的，上述方法还包括：周期性的或在某些触发条件下(例如，有通信的需求的情况下，通信链路的链路质量不满足要求的情况下)检测设备的屏下天线遮挡信息；根据检测到的设备的屏下天线遮挡信息更新第二天线集合。由于用户在操作设备的过程中，手部动作会不断的变化，因此，对于屏下天线的遮挡也是一直变化的。该可选的方法，通过更新第二天线集合，可以保证选择出的第一天线集合根据最新的第二天线集合确定，保证通信质量。
在更新第二天线集合之后，可以判断是否更新第一天线集合，在确定更新第一天线集合的情况下，还更新第一天线集合。例如，当确定第二天线集合中的天线个数增多时，意味着有更多的天线可以用于通信(例如，波束赋形的天线增益可以更大，MIMO的规格可以更高)，此时，可以确定更新第一天线集合。
可选的，在根据屏下天线遮挡信息确定第一天线集合之后，上述方法还包括：确定设备的通信链路的链路质量是否满足要求，若否，更新第一天线集合；或者，接收指示信息，指示信息用于指示更新第一天线集合或用于指示通信链路的链路质量不满足要求，此时，更新第一天线集合。该可选的方法，可以根据通信链路的链路质量对第一天线集合进行更新，从而使得当前使用的第一天线集合能够满足通信链路的链路质量要求。
其中，网络设备可以在设备的通信链路的链路质量不满足要求的情况下，向设备发送指示信息。例如，当网络设备发现通信链路当前的服务质量(quality of service，QoS)低于通信链路所需的QoS，或者，网络设备发现通信链路存在多次重传现象，或者，网络设备发现通信链路的误块率(block error rate，BLER)无法满足系统要求时，可以认为通信链路的链路质量不满足要求。
需要说明的是，一次完整的通信过程中(例如，一次游戏进行过程)，在不同时间段用户操作行为可能发生改变，导致屏下天线遮挡情况也随之发生变化。该情况下，可以采用以下方案1或方案2实现上述方法。
方案1
在方案1中，在确定第一天线集合之后，通信链路的链路质量不满足要求时，触发第一天线集合(或第二天线集合)的更新。
参见图16，方案1在具体实现时包括：
1601、确定设备有通信需求。
1602、确定第二天线集合。
1603、在第二天线集合中确定第一天线集合。
1604、周期性确定通信链路的链路质量是否满足要求。
若是，执行步骤1605-步骤1606，若否，返回步骤1602或步骤1603(图16中以返回至步骤1603进行示意)。
1605、采用第一天线集合进行信号传输。
1606、判断本次通信是否完成。
若是，结束，若否，返回步骤1604。
方案2
在方案2中，在确定第一天线集合之后，通信链路的链路质量不满足要求时，触发第一天线集合(或第二天线集合)的更新，并且可以周期性的进行第二天线集合的更新。
参见图17，方案2在具体实现时包括：
1701-1706、与步骤1601-步骤1606分别相同。
1707、每隔预设时间段，更新第二天线集合(即周期性的更新第二天线集合)。
1708、判断是否更新第一天线集合。
若是，执行动作1709，若否，不执行任何动作。
1709、更新第一天线集合。
在执行步骤1709后执行动作1705。
上述实施例提供的方法在具体实现时，各个方案之间可以进行组合，例如，参见图18，凡是通过箭头指向连接在一起的方案之间均可以进行结合。
本申请实施例中，除了采用设备的屏幕中的电容层、上述传感器等确定被遮挡区域之外，还可以通过对遮挡物进行定位等方式确定被遮挡区域。例如，对遮挡物与设备的相对空间位置进行直接定位，比如设备某个位置设置为空间原点(0，0，0)，然后检测到遮挡物的空间坐标是(x，y，z)，然后通过几何计算确定设备的屏幕的被遮挡区域。
上述主要从方法的角度对本申请实施例的方案进行了介绍。可以理解的是，屏下天线的管理装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和软件模块中的至少一个。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
本申请实施例可以根据上述方法示例对屏下天线的管理装置进行功能单元的划分，例如，可以对应各个功能划分各个功能单元，也可以将两个或两个以上的功能集成在一个处理单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。需要说明的是，本申请实施例中对单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
例如，本申请实施例提供的方法的执行主体可以包括多个功能模块用于执行上述方法。例如，假设本申请实施例提供的方法的执行主体为本申请中的设备，参见图19，该设备包括：检测模块、屏下天线模块和通信模块。可选的，还包括控制模块。其中，检测模块用于获取设备的屏下天线遮挡信息，并判断屏下天线是否被遮挡，具体可以通过上述接触式或非接触式的方式实现。通信模块，用于与其他设备之间进行通信，例如，采用第一天线集合与其他设备之间进行信号传输。通信模块需要使用屏下天线 模块进行信号传输。屏下天线模块用于发送和/或接收电磁信号。若通信模块是光通信模块，则屏下天线模块用于发送和/或接收光信号(注：本申请中为方便统一称为天线，实际在光通信领域，通常称其为传感器，即发射光传感器或者接收光传感器)。控制模块用于控制上述三个功能模块，实现本申请提供的方法。通信模块/控制模块还用于执行以下动作中的一个或多个：在第二天线集合中确定第一天线集合，建立第一区域、第二区域和第三区域中的一个或多个与屏下天线之间的对应关系，在第二天线集合中的天线个数小于传输模式所需的天线个数的情况下，确定结束本次通还是降低天线的使用数量，更新第一天线集合，更新第二天线集合，判断是否更新第一天线集合等。
其中，检测模块可以为设备的屏幕中的电容层、上述传感器等，通信模块可以为通信接口、收发器(例如，收发电路)、输入接口和/或输出接口等，控制模块可以为处理器。
