本申请涉及计算机技术领域，尤其涉及一种射频前端模组、可穿戴设备、数据传输方法和计算机可读存储介质。
背景技术
可穿戴设备是直接穿在用户身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能，可穿戴设备将会对人类的生活、感知带来很大的转变。例如，智能头戴式设备中的增强现实(Augmented Reality，AR)眼镜，是将AR技术应用于眼镜上，除了能够实现普通眼镜的功能外，还可以实现导航、打电话、观看视频等功能，因此，受到了广大用户的青睐。
可穿戴设备对重量、体积、功耗和发热等参数有非常严格的要求，否则将会极度影响用户的使用体验。因此，常见的轻量级可穿戴设备会和终端紧密结合起来。以可穿戴设备是AR眼镜、终端是手机为例，AR眼镜中的显示和音频部分的电路分配在眼镜上，而中央数据处理芯片(运算过程功耗较大，且发热较大)部分的电路则分配在手机上，以减轻AR眼镜的重量、功耗、体积和发热性能等。
可穿戴设备与终端通过无线通信连接，以实现数据传输，为了保证信号具有足够的覆盖范围，可穿戴设备和终端上需要搭配射频前端模组(Radio Front-end Modules，RFEM)。然而，射频前端模组在放大发射信号和接收信号的同时，增加了射频前端模组的功耗，也增加了可穿戴设备的功耗。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。应当理解的是，此处所描述的一些实施例仅仅用以解释本申请的技术方案，并不用于限定本申请的技术范围。
为了更好地理解本申请实施例中提供的可穿戴设备，在对本申请实施例的技术方案进行介绍之前，先对可穿戴设备以及相关技术进行说明。
增强现实技术是一种将虚拟信息与真实世界巧妙融合的技术，广泛运用了多媒体、三维建模、实时跟踪及注册、智能交互、传感等多种技术手段，将计算机生成的文字、图像、三维模型、音乐、视频等虚拟信息模拟仿真后，应用到真实世界中，两种信息互为补充，从而实现对真实世界的“增强”。
在本申请实施例中，可穿戴设备包括但不限于智能手表、智能项链、可穿戴电子袜子、可穿戴眼镜和智能服装。以可穿戴设备是AR眼镜为例，AR眼镜是一种把AR技术应用在电子眼镜上的产品，可以实现诸多功能，可以将AR眼镜看作是一台微型的手机，通过跟踪眼球视线轨迹判断用户处于的状态，开启相应功能。
常见的轻量级可穿戴设备会和终端紧密结合起来，示例性的，可穿戴设备可以通过无线通信技术与终端进行连接，无线通信技术包括但不限于蓝牙和无线局域网(Wireless Local Area Network，WLAN)，WLAN可以包括WIFI。通过无线通信技术实现计算机设备的互相连通，构成互相通信和实现资源共享的网络体系。通过无线通信技术连接，不需要使用通信电缆， 就可以将计算机与网络连接起来，从而使得网络的构建和终端的移动更加灵活。
示例性的，以可穿戴设备是AR眼镜、终端是手机、无线通信技术是WIFI为例进行说明，AR眼镜通过WIFI与手机进行无线连接，WIFI具有高稳定性、低延时和较高的交换带宽(例如，Gbps数量级)的传输速率等优点，可以为AR眼镜与手机提供快速的数据传输方案。但是WIFI也有其自身的局限性，为了保证足够的覆盖范围(通常数十米范围)，其外围电路(即，AR眼镜和手机)需要搭配射频前端模组，用来保证其发射信号和接收信号的功率放大，进而导致功耗的增加。由于AR眼镜采用眼镜与手机相结合的方案，因此AR眼镜和手机需要采用一种低延时，高速率和低功耗的传输方式，以便于AR眼镜和手机之间的数据传输。
相关技术中，一种方式是通过压缩图形质量降低对传输速率的要求，从而降低功耗。同时也降低了数据的准确性。
另一种方式中，通过增加电池容量和散热设备，以支持高功耗的影响。增加附件，同时也增加了可穿戴设备的重量。
再一种方式中，如图1所示，图1为本申请实施例提供的一种可穿戴设备的示例性的应用场景示意图。图1中以可穿戴设备是AR眼镜、终端是手机、功率放大模组是功率模块为例进行说明，可穿戴设备包括射频前端模组，射频前端模组包括功率模块，当手机接近AR眼镜时，图1中以近距离表示，控制手机动态，调整手机和AR眼镜的发射功率，从而减少传输功率，以降低功耗(即降低功率)。当手机远离AR眼镜时，图1以远距离表示，手机和AR眼镜均以最高功率进行发射和接收。由于AR眼镜与手机之间的使用距离通常是近距离(例如，5m以内)，通过降低手机和AR眼镜的发射功率的方式，对于手机而言，功耗已经降低，但是对于AR眼镜来说，其功耗依然很高。
基于上述提出的技术问题，本申请实施例提供一种射频前端模组，如 图2所示，图2为本申请实施例提供的一种射频前端模组的可选的结构示意图。
射频前端模组20包括：逻辑控制接口201、功率放大模组202和天线203；逻辑控制接口201，被配置为接收功率控制信号，将功率控制信号传输至功率放大模组202；功率放大模组202，被配置为根据功率控制信号，控制功率放大模组202的N个功率放大器处于工作状态，并通过N个功率放大器对发射信号进行放大，得到放大发射信号，N为小于M的正整数，M为功率放大器总数量；天线203，被配置为将放大发射信号传输至终端。
在本申请实施例中，图2中射频前端模组20可以应用于可穿戴设备，射频前端模组20包括逻辑控制接口201、功率放大模组202和天线203。逻辑控制接口201用于表示不同的逻辑控制状态，可以理解为通过逻辑控制接口201中自身接口上不同的输入表示不同的连接状态，不同的连接状态与功率放大模组202中不同的功率放大器的工作状态相对应。逻辑控制接口201接收功率控制信号，功率控制信号表征功率放大模组202中需要工作的功率放大器的数量。逻辑控制接口201根据功率控制信号对自身接口的连接状态进行设置，然后将功率控制信号传输至功率放大模组202，使得功率放大模组202根据功率控制信号，控制其中一部分的功率放大器(即N个功率放大器)处于工作状态，减少了多余的处于工作状态的功率放大器的数量。当可穿戴设备通过射频前端模组20向终端发送信号(即发射信号)时，通过N个功率放大器对发射信号进行放大，得到放大发射信号，再通过天线203将放大发射信号传输至终端。
在本申请实施例中，功率放大模组202包括M个功率放大器，M为大于或等于2的正整数。也可以理解为功率放大模组202是多级放大器，当M等于1时，功率放大模组202是单级放大器。当可穿戴设备通过射频前端模组20向终端发送信号(即发射信号)时，控制功率放大模组202的N个功率放大器处于工作状态，而不是整个M个功率放大器处于工作状态， 从而降低功率放大模组202的功耗。
示例性的，以可穿戴设备是AR眼镜、终端是手机为例，可以理解的是，相较于图1中通过降低手机和AR眼镜的发射功率的方式，在本申请实施例中，降低AR眼镜的发射功率，小幅降低或者不降低手机的发射功率，使得AR眼镜的发射功率的降低幅度远远大于图1中的AR眼镜，从而降低了可穿戴设备的功耗。
需要说明的是，可穿戴设备和终端上均搭配射频前端模组20，射频前端模组20属于硬件电路，可以完成射频信号的发送放大以及接收放大，即发射信号的放大和接收信号的放大，还可以用于功率耦合、逻辑控制和开关切换等。由于终端对于功耗的敏感度小于可穿戴设备，本申请实施例中结合实际应用场景，即，可穿戴设备与终端的使用距离较近，不需要很大的发射功率，因此，通过减少可穿戴设备中功率放大模组202中处于工作状态的功率放大器的数量，在不影响可穿戴设备与终端之间通信质量的前提下，降低射频前端模组20的发射功率，从而降低可穿戴设备的功耗。
本申请实施例提供的射频前端模组20包括：逻辑控制接口201、功率放大模组202和天线203；逻辑控制接口201，被配置为接收功率控制信号，将功率控制信号传输至功率放大模组202；功率放大模组202，被配置为根据功率控制信号，控制功率放大模组202的N个功率放大器处于工作状态，并通过N个功率放大器对发射信号进行放大，得到放大发射信号；N小于功率放大器总数量。天线203，被配置为将放大发射信号传输至终端，以在终端对放大发射信号所对应的数据进行处理。在可穿戴设备和终端相互通信的过程中，大部分时间，数据是从终端传输到可穿戴设备。因此，本申请实施例通过控制功率放大模组202的N个功率放大器处于工作状态，减少处于工作状态的功率放大器的数量，而不是整个功率放大模组202(即M个功率放大器)处于工作状态。在保证功率放大器的效率前提下，适当降低了功率放大模组202的增益和线性度指标，降低了射频前端模组20的功 耗，从而降低可穿戴设备的功耗。
在一些实施例中，本申请实施例提供的另一种射频前端模组的可选的结构示意图，如图3所示，基于图2的射频前端模组20，图3中射频前端模组20，还包括：功率耦合电路204；功率耦合电路204分别与功率放大模组202和天线203连接；功率耦合电路204，被配置为对放大发射信号的功率进行分配，得到目标发射信号，将目标发射信号传输至天线203；天线203，被配置为将目标发射信号传输至终端。
在本申请实施例中，在通过N个功率放大器对发射信号进行放大，得到放大发射信号之后，放大发射信号通过功率耦合电路204，一小部分信号进入耦合端口，一大部分信号进入天线203，即目标发射信号，然后通过天线203将目标发射信号传输至终端。由于天线203将目标发射信号传输至终端，不知道目标发射信号的功率，因此，本申请实施例还可以根据进入耦合端口的一小部分信号，计算目标发射信号的功率。
示例性的，放大发射信号通过功率耦合电路204之后，1％的功率信号进入耦合端口，99％的功率信号进入天线203，可以根据进入耦合端口的1％的功率信号，计算目标发射信号的功率，从而确定天线203辐射的目标发射信号的能量。
需要说明的是，功率耦合电路204，也可以表示为CPL或CPLR，可以理解为一种应用于微波系统的分路器，将主干通道上的功率按需分配到每个枝干通道上，以达到分路功能。
在本申请实施例中，射频前端模组20还包括功率耦合电路204；通过功率耦合电路204分别与功率放大模组202和天线203连接；功率耦合电路204，被配置为对放大发射信号的功率进行分配，得到目标发射信号，还可以计算目标发射信号的功率。然后将目标发射信号传输至天线203，通过天线203将目标发射信号传输至终端。根据目标发射信号的功率可以及时对本次功率放大模组202的调整结果进行检验，对下一次处于工作状态的 功率放大器的数量调整提供参考，以便后续更准确的减少处于工作状态的功率放大器的数量，降低功率放大模组202的功耗。
在一些实施例中，功率耦合电路204，还被配置为对放大发射信号的功率进行分配，得到耦合端口功率；根据耦合端口功率生成新的功率控制信号，并向逻辑控制接口201发送新的功率控制信号，新的功率控制信号用于在下一次向终端传输信号时确定处于工作状态的功率放大器的数量。
在本申请实施例中，功率耦合电路204对放大发射信号的功率进行分配，一小部分信号进入耦合端口，一大部分信号进入天线203，即目标发射信号。根据进入耦合端口一小部分信号，可以得到耦合端口功率。然后，根据耦合端口功率生成新的功率控制信号，并向逻辑控制接口201发送新的功率控制信号，新的功率控制信号用于在下一次向终端传输信号时确定处于工作状态的功率放大器的数量。使得功率放大模组对发射信号进行放大，得到的放大发射信号的功率更合适。
在本申请实施例中，根据功率耦合电路204的功率分配比例和耦合端口功率，计算目标发射信号的功率。根据目标发射信号的功率，可以对本次功率放大模组202中处于工作状态的功率放大器的数量是否合适进行判断。
示例性的，若目标发射信号的功率过大，则需要减少下一次功率放大模组202中处于工作状态的功率放大器的数量；若目标发射信号的功率合适，则保持下一次功率放大模组202中处于工作状态的功率放大器的数量；若目标发射信号的功率过小，则需要增加下一次功率放大模组202中处于工作状态的功率放大器的数量。
需要说明的是，本申请实施例中是功率耦合电路204根据耦合端口功率生成新的功率控制信号，并向逻辑控制接口201发送新的功率控制信号。可以理解的是，也可以由功率耦合电路204将耦合端口功率发送至功率控制信号生成模块，由功率控制信号生成模块根据耦合端口功率生成新的功 率控制信号，并向逻辑控制接口201发送新的功率控制信号。本申请实施例对于生成功率控制信号的执行主体不做限制。
在本申请实施例中，若目标发射信号的功率过大或过小，则根据耦合端口功率生成新的功率控制信号，并向逻辑控制接口201发送新的功率控制信号，根据新的功率控制信号确定处于工作状态的功率放大器的数量。从而在下一次向终端传输信号时，提高了以下方面的准确性：减少处于工作状态的功率放大器的数量，降低功率放大模组202的功耗。
在一些实施例中，逻辑控制接口201包括多个子接口；多个子接口，被配置为根据功率控制信号调整其输出电平值，其中，多个子接口的输出电平值控制功率放大模组202的M个功率放大器的工作状态。
在本申请实施例中，逻辑控制接口201接收功率控制信号之后，根据功率控制信号调整多个子接口的输出电平值，输出电平值包括高电平和低电平，多个子接口的不同的输出电平值组合，响应于不同的功率控制信号。从而实现控制功率放大模组202中处于工作状态的功率放大器的数量，也就是实现控制功率放大模组202的M个功率放大器的工作状态。
示例性的，以逻辑控制接口201包括4个接口：PAEN、LNAEN、SEL3和SEL4为例进行说明，PAEN、LNAEN、SEL3和SEL4的输出电平值包括高电平和低电平，SEL3和SEL4可以用于控制射频前端模组20休眠、选择不同的开关以实现不同的功能。以1表示高电平、以0表示低电平为例进行说明，4个接口的不同输出电平值可以有多种表现形式，例如，当PAEN、LNAEN、SEL3和SEL4的输出电平值分别为1 0 0 0时，功率放大模组202中处于工作状态的功率放大器的数量是3个，当PAEN、LNAEN、SEL3和SEL4的输出电平值分别为1 0 1 0时，功率放大模组202中处于工作状态的功率放大器的数量是2个，当PAEN、LNAEN、SEL3和SEL4的输出电平值分别为1 1 1 0时，功率放大模组202中处于工作状态的功率放大器的数量是1个。
需要说明的是，逻辑控制接口201可以是通用型之输入输出(General-purpose input/output，GPIO)控制线组。GPIO控制线组包括多个端口，其端口可以由计算机程序进行控制，自由使用，通过GPIO控制线组对特定的端口进行设置，实现控制功率放大模组202的N个功率放大器处于工作状态。也可以由监控芯片(watchdog)控制GPIO控制线组，通过GPIO控制线组中不同端口的接入，从而控制功率放大模组202处于工作状态的功率放大器的数量。
在本申请实施例中，逻辑控制接口201包括多个子接口，根据功率控制信号调整逻辑控制接口201中多个子接口的输出电平值，控制功率放大模组202的N个功率放大器处于工作状态。使得功率放大模组202接收到发射信号时，通过N个功率放大器对发射信号进行放大，而不是整个功率放大模组202(即M个功率放大器)处于工作状态。减少处于工作状态的功率放大器的数量，从而降低功率放大模组202的功耗。
在一些实施例中，射频前端模组20的数量为多个；天线203，被配置为在不同的通信频段，与终端进行信号传输；不同的通信频段分别对应不同的射频前端模组20。
在本申请实施例中，可穿戴设备和终端上可以搭配多个射频前端模组20，也就是采用多进多出(multiple-in multipleout，MIMO)技术，示例性的，2×2MIMO需要可穿戴设备和终端上均搭配两个射频前端模组20。MIMO可以为极大地提高信道容量，在发送端和接收端都使用多根天线203，在收发之间构成多个通道的天线203系统，从而提高可穿戴设备和终端的数据传输效率。
在一些实施例中，天线203，被配置为在第五代移动通信技术(5th Generation Mobile Communication Technology，5G)或第六代移动通信技术(6G)，与终端进行信号传输；第五代移动通信技术或第六代移动通信技术分别对应不同的射频前端模组20。
需要说明的是，通信频段包括但不限于频段5.150GHz-5.935GHz，5.935GHz-7.125GHz，即，5G技术和6G技术，可以理解的是，本申请实施例提供的射频前端模组20同样适用于3G技术，4G技术等，并且，随着技术的发展，本申请实施例提供的射频前端模组20也适用于7G技术、8G技术、9G技术、10G技术等，对此本申请实施例不做限制。
在本申请实施例中，不同的通信频段采用不同的射频前端模组20进行数据传输，可以同时支持多个通信频段的数据传输，并且提高了数据传输的效率。
下面，将说明本申请实施例在一个实际的应用场景中的示例性应用。
本申请实施例以逻辑控制接口包括SEL/LNAEN/PAEN控制线、功率放大模组是功率放大器(Power Amplifier，PA)、天线是antenna(ANT)、功率耦合电路是CPL为例进行说明，如图4所示，图4为本申请实施例提供的再一种射频前端模组的可选的结构示意图，其中，SEL/LNAEN/PAEN(图4中以SEL4_x、SEL3_x、LNAEN_x、PAEN_x示出)对应于图2和图3中逻辑控制接口201，PA对应于图2和图3中功率放大模组202，ANT对应于图2和图3中天线203，CPL对应于图3中功率耦合电路204。
在本申请实施例中，图4中示出的射频前端模组20可以应用于可穿戴设备和终端。若可穿戴设备和终端采用2×2MIMO的方案，则可穿戴设备和终端需要均搭配两个射频前端模组，因此图4中包括两个发射通道(Transmit，T)和两个接收通道(Receive，R)，两个发射通道包括TX1和TX0，两个接收通道包括RX1和RX0，其中，X是一个象形的表示交叉(cross)的符号，可以理解为A方的TX接B方的RX、B方的TX接A方的RX，两个发射/接收通道均相同，可以以一个发射/接收通道为例进行说明。
在本申请实施例中，图4中发射通道TX包括功率放大器PA，功率放大器PA用于发射信号的放大，接收通道RX包括低噪声放大器(low noise  amplifier，LNA)，低噪声放大器LNA用于接收信号放大。图4中开关S0用于切换发射通道TX和接收通道RX的工作状态，在可穿戴设备通过射频前端模组20向终端发送信号时，开关S0的连接方式如图4所示，将功率耦合电路CPL与ANT(ANT0或ANT1)连接，图4中的CPLR(CPLR0或CPLR1)表示功率耦合电路CPL的耦合端口。在可穿戴设备接收终端发送的信号时，通过控制开关S0，将ANT与低噪声放大器LNA、S相互连接。S为控制低噪声放大器LNA处于通路或短路状态的开关。图4中的Vcc表示电源连接，GND表示接地，C表示电容，L表示电感。图4中的功率耦合电路CPL用于耦合功率的检测，SEL/LNAEN/PAEN控制线用于逻辑状态控制。
在本申请实施例中，是通过降低发射通道TX中功率放大器PA的功耗，降低射频前端模组20的功耗，从而降低可穿戴设备的功耗，在此，对发射通道TX中的功率放大器PA进行说明。通常情况下，为了得到足够大的放大倍数或考虑到输入电阻、输出电阻等多种要求，功率放大器PA由多级电路组成，即多级放大器，也可以理解为功率放大模组包括M个功率放大器。如图5所示，图5为本申请实施例提供的一种功率放大模组的可选的结构示意图。也就是多级放大器的结构框图，图5示出的是三级功率放大器，其中，输入级用于完成与信号源的衔接，并对信号进行放大；中间级用于电压放大，将微弱的输入电压放大到足够的电压幅度；输出级用于信号的功率放大，以达到满足输出负载需要的功率，并要求和负载相匹配。
在本申请实施例中，以可穿戴设备是AR眼镜、终端是手机、无线通信技术是WIFI为例进行说明，由于AR眼镜与手机之间的使用距离通常是近距离(例如5m以内)，不需要像手机或者路由器产品那样需要远距离(例如数十米)的覆盖距离。同时，AR眼镜与手机之间的数据通信，大部分时间是从手机传送至AR眼镜，也就是说AR眼镜大部分时间处于接收状态，对发射功率和发射信号质量要求相对较低，可以在保证功率放大器PA的效 率的同时，适当牺牲功率放大器PA的增益和线性度指标。
在本申请实施例中，通过控制SEL/LNAEN/PAEN控制线的输出电平值，将功率放大器PA的工作模式设置为单级放大。示例性的，当PAEN、LNAEN、SEL3和SEL4的输出电平值为1 0 0 0时，发射通道中功率放大器为3级放大器，发射通道所对应的电流值是330mA。当PAEN、LNAEN、SEL3和SEL4的输出电平值是1 1 1 0时，发射通道中功率放大器为单级放大器，发射通道所对应的电流值是60mA，从而有效降低了功率放大器的功耗。
本申请实施例针对WIFI高速传输过程中功耗很高的技术问题，结合AR眼镜本身的应用场景，通过软件手段，根据SEL/LNAEN/PAEN控制线的输出电平值，对发射通道TX中的功率放大器PA的级数进行控制，强行控制射频前端模组20中的功率放大器PA从多级放大变成单级放大，进而节省了中间级和输出级的功耗，使得射频前端模组20在辐射功率时的功耗降至原来的20％，在保证传输速率的同时，降低了AR眼镜WIFI高速传输时的功耗。
本申请实施例提供一种数据传输方法，该数据传输方法可以应用于以上任意实施例所描述的射频前端模组20。如图6所示，图6为本申请实施例提供的一种数据传输方法的步骤流程图，数据传输方法包括以下步骤：
S601、接收功率控制信号。
S602、根据功率控制信号，控制功率放大模组的N个功率放大器处于工作状态，N为小于M的正整数，M为功率放大器总数量。
S603、当接收到发射信号时，通过处于工作状态的N个功率放大器对发射信号进行放大，得到放大发射信号。
S604、传输放大发射信号至终端。
本申请实施例提供的数据传输方法应用于可穿戴设备的射频前端模组，通过接收功率控制信号；根据功率控制信号，控制功率放大模组的N个功率放大器处于工作状态，N小于功率放大模组的功率放大器总数量。当接 收到发射信号时，通过处于工作状态的N个功率放大器对发射信号进行放大，得到放大发射信号。传输放大发射信号至终端，以在终端对放大发射信号所对应的数据进行处理。在可穿戴设备和终端相互通信的过程中，大部分时间，数据是从终端传输到可穿戴设备。因此，本申请实施例通过控制功率放大模组的N个功率放大器处于工作状态，减少处于工作状态的功率放大器的数量，而不是整个功率放大模组(即M个功率放大器)处于工作状态。在保证功率放大器的效率前提下，适当降低了功率放大模组的增益和线性度指标，降低射频前端模组的功耗，从而降低可穿戴设备的功耗。
在一些实施例中，射频前端模组中逻辑控制接口包括多个子接口，上述S602还可以通过以下方式实现，根据功率控制信号调整多个子接口的输出电平值，控制功率放大模组的N个功率放大器处于工作状态；其中，多个子接口的输出电平值控制功率放大模组的M个功率放大器的工作状态。
在一些实施例中，上述S604还可以通过以下方式实现，对放大发射信号的功率进行分配，得到目标发射信号；将目标发射信号传输至终端。
在一些实施例中，数据传输方法还可以包括以下步骤：对放大发射信号的功率进行分配，得到耦合端口功率；根据耦合端口功率生成新的功率控制信号，新的功率控制信号用于在下一次向终端传输信号时确定处于工作状态的功率放大器的数量。
在一些实施例中，射频前端模组的数量为多个，在不同的通信频段，与终端进行信号传输；不同的通信频段分别对应不同的射频前端模组。
在一些实施例中，在第五代移动通信技术或第六代移动通信技术对应的通信频段，与终端进行信号传输；第五代移动通信技术和第六代移动通信技术分别对应不同的射频前端模组。
