近年来，零功耗设备的应用越来越广泛。一种典型的零功耗设备是无线射频识别(Radio Frequency Identification，RFID)，它是利用收发端无线电耦合的方式，实现无接触的标签信息自动传输与识别的技术。这包括了近距离的电感耦合和远距离的电磁耦合。RFID标签又称为“射频标签”或“电子标签”。根据供电方式的不同来划分的电子标签的类型，可以分为有源电子标签，无源电子标签和半无源电子标签。有源电子标签，又称为主动式电子标签，是指电子标签内置电池提供工作的能量。不同于被动射频的激活方式，标签可主动在设定频段发送信息。无源电子标签，又称为被动式电子标签，其不支持内装电池。无源电子标签接近读写器时，处于读写器天线辐射形成的近场范围内的电子标签天线通过电磁感应产生感应电流，感应电流驱动电子标签芯片电路。芯片电路通过电子标签天线将存储在标签中的标识信息发送给读写器。半主动式电子标签继承了无源电子标签体积小、重量轻、价格低、使用寿命长的优点，内置的电池在没有读写器访问的时候，只为芯片内很少的电路提供电源，只有在读写器访问时，内置电池向RFID芯片供电，以增加标签的读写距离，提高通信的可靠性。
作为一种无线通信技术，最基本的RFID系统是由电子标签(TAG)和读写器(Reader/Writer)两部分构成。电子标签：它由耦合组件及芯片构成，每个电子标签都有独特的电子编码，放在被测目标上以达到标记目标物体的目的。读写器：不仅能够读取电子标签上的信息，而且还能够写入电子标签上的信息，同时为电子标签提供通信所需要的能量。如图2所示。电子标签进入电磁场后，接收读写器发出的射频信号，无源电子标签或者被动电子标签利用空间中产生的电磁场得到的能量，将电子标签存储的信息传送出去，读写器读取信息并且进行解码，从而识别电子标签。
RFID是一种零功耗通信。这类零功耗通信关键技术，包括了能量采集和反向散射通信以及低功耗计算。如图2所示，一个典型的零功耗通信系统包括读写器和零功耗终端。读写器发射无线电波，用于向零功耗终端提供能量。安装在零功耗终端的能量采集模块可以采集空间中的无线电波携带的能量(图2中所示为读写器发射的无线电波)，用于驱动零功耗终端的低功耗计算模块和实现反向散射通信。零功耗终端获得能量后，可以接收读写器的控制命令并基于控制信令基于后向散射的方式向读写器发送数据。所发送的数据可以来自于零功耗终端自身存储的数据(如身份标识或预先写入的信息，如商品的生产日期、品牌、生产厂家等)。零功耗终端也可以加载各类传感器，从而基于零功耗机制将各类传感器采集的数据上报。
零功耗通信采用能量采集和反向散射通信技术。零功耗通信网络由网络设备和零功耗终端构成。如图2所示，网络设备用于向零功耗终端发送无线供能信号，下行通信信号以及接收零功耗终端的反向散射信号。一个基本的零功耗终端包含能量采集模块，反向散射通信模块以及低功耗计算模块。此外，零功耗终端还可具备一个存储器或传感器，用于存储一些基本信息(如物品标识等)或获取环境温度、环境湿度等传感数据。
以下，对零功耗通信中的关键技术进行说明。
无线射频能量采集(Radio Frequency Power Harvesting)
如图3所示，射频能量采集模块基于电磁感应原理实现对空间电磁波能量的采集，进而获得驱动零功耗终端工作所需的能量，例如用于驱动低功耗解调以及调制模块、传感器以及内存读取等。因此，零功耗终端无需传统电池。
反向散射通信(Back Scattering)
如图4所示，零功耗终端接收网络设备发送的载波信号，并对所述载波信号进行调制，加载需要发送的信息并将调制后的信号从天线辐射出去，这一信息传输过程称之为反向散射通信。反向散射和负载调制功能密不可分。负载调制通过对零功耗终端的振荡回路的电路参数按照数据流的节拍进行调 节和控制，使电子标签阻抗的大小等参数随之改变，从而完成调制的过程。负载调制技术主要包括电阻负载调制和电容负载调制两种方式。在电阻负载调制中，负载并联一个电阻，该电阻基于二进制数据流的控制接通或断开，如图5所示。电阻的通断会导致电路电压的变化，因此实现幅度键控调制(ASK)，即通过调整零功耗终端的反向散射信号的幅度大小实现信号的调制与传输。类似地，在电容负载调制中，通过电容的通断可以实现电路谐振频率的变化，实现频率键控调制(FSK)，即通过调整零功耗终端的反向散射信号的工作频率实现信号的调制与传输。
可见，零功耗终端借助于负载调制的方式，对来波信号进行信息调制，从而实现反向散射通信过程。因此，零功耗终端具有显著的优点：
(1)终端不主动发射信号，因此不需要复杂的射频链路，如PA、射频滤波器等；
(2)终端不需要主动产生高频信号，因此不需要高频晶振；
(3)借助反向散射通信，终端信号传输不需要消耗终端自身能量。
编码技术
电子标签传输的数据，可以用不同形式的代码来表示二进制的“1”和“0”。无线射频识别系统通常使用下列编码方法中的一种：反向不归零(NRZ)编码、曼彻斯特(Manchester)编码、单极性归零(Unipolar RZ)编码、差动双相(DBP)编码、差动编码、脉冲间隔编码(PIE)、双向空间编码(FM0)、米勒(Miller)编码利差动编码等。通俗来说，是采用不同的脉冲信号表示0和1。
在一些场景中，基于零功耗终端的能量来源以及使用方式，可以将零功耗终端分为无源零功耗终端、半无源零功耗终端和有源零功耗终端。
无源零功耗终端
零功耗终端不需要内装电池，零功耗终端接近网络设备(如RFID系统的读写器)时，零功耗终端处于网络设备天线辐射形成的近场范围内。因此，零功耗终端天线通过电磁感应产生感应电流，感应电流驱动零功耗终端的低功耗芯片电路。实现对前向链路信号的解调，以及反向链路的信号调制等工作。对于反向散射链路，零功耗终端使用反向散射实现方式进行信号的传输。
可以看出，无源零功耗终端无论是前向链路还是反向链路都不需要内置电池来驱动，是一种真正意义的零功耗终端。
无源零功耗终端不需要电池，射频电路以及基带电路都非常简单，例如不需要低噪放(LNA)，功放(PA)，晶振，模数转换器(Analog-to-Digital Converter，ADC)等器件，因此具有体积小、重量轻、价格非常便宜、使用寿命长等诸多优点。
半无源零功耗终端
半无源零功耗终端自身也不安装常规电池，但可使用RF能量采集模块采集无线电波能量，同时将采集的能量存储于一个储能单元(如电容)中。储能单元获得能量后，可以驱动零功耗终端的低功耗芯片电路。实现对前向链路信号的解调，以及反向链路的信号调制等工作。对于反向散射链路，零功耗终端使用反向散射实现方式进行信号的传输。
可以看出，半无源零功耗终端无论是前向链路还是反向链路都不需要内置电池来驱动，虽然工作中使用了电容储存的能量，但能量来源于能量采集模块采集的无线电能量，因此也是一种真正意义的零功耗终端。
半无源零功耗终端继承了无源零功耗终端的诸多优点，因此具有体积小、重量轻、价格非常便宜、使用寿命长等诸多优点。
有源零功耗终端
有些场景下使用的零功耗终端也可以为有源零功耗终端，此类终端可以内置电池。电池用于驱动零功耗终端的低功耗芯片电路。实现对前向链路信号的解调，以及反向链路的信号调制等工作。但对于反向散射链路，零功耗终端使用反向散射实现方式进行信号的传输。因此，这类终端的零功耗主要体现于反向链路的信号传输不需要终端自身功率，而是使用反向散射的方式。
有源零功耗终端，内置电池向RFID芯片供电，以增加标签的读写距离，提高通信的可靠性。因此在一些对通信距离，读取时延等方面要求相对较高的场景得以应用。
接收信号强度(Received Signal Strength，RSS)定位
RSS定位技术是依据信号强度随传播距离的变化规律实现定位的一类方法，其定位核心是根据多个参考节点接收同一目标源的信号强度来实现目标位置的确定。RSS定位技术目前被广泛应用于室内定位。传统的基于几何测量法的RSS定位技术首先需要测出各监测节点接收到目标的信号强度RSS，然后根据信号传输衰减模型逆向推算出各节点与目标间的传播距离d，进而估算待定位信号源的相对地理位置。
蜂窝无源物联网
随着5G行业应用增加，连接物的种类和应用场景越来越多，对通信终端的价格和功耗也将有更高要求。免电池、低成本的无源物联网设备的应用成为蜂窝物联网的关键技术，充实5G网络链接终端类型和数量，真正实现万物互联。其中无源物联网设备可以基于现有的零功耗设备，运用于蜂窝物联网。
副载波调制
副载波调制是指首先把信号调制在载波1(即副载波)上，处于某种原因，决定再进行一次调制，于是用这个结果再去调制另外一个频率更高的载波2。副载波调制是RFID系统经常采用的一种调制方式。
在蜂窝网络中，传统的终端设备需要电池供电。在蜂窝网络中引入零功耗终端，则需要通过基站或其他来源提供供能信号，用于零功耗设备获得能量。在图6中，零功耗终端通过下行(downlink，DL)频率提供触发信号和能量。通过反向散射(back scattering)在上行(uplink，UL)频率向基站反馈信息。反向散射的时间和频率可以和入射的信号不同。图6中发射频域会产生对称的频移反射，通过滤波器等技术仅拾取其中一个频点。
在一些实施例中，通过反射处理定时(延时)机制，也可以在特定的时间反射信号，即可以控制反向散射的时间。
为了便于理解本申请实施例，以下对本申请所解决的问题进行说明。
将零功耗技术应用到蜂窝网中，需要有序地协调多个终端使用不同的时频资源。以NR系统为例子，蜂窝网络可以灵活地配置不同频率的资源。在频分双工(Frequency Division Duplex，FDD)的双工方式下，网络设备在DL资源上传输信号，相应的终端应该在UL资源上传输信号。DL和UL通过频率的方式分开。在UL上，网络设备中有多个终端进行反射信号，需要多个终端的时频资源指示。如何能够让不同的终端占用不同的资源，如时域，频域甚至是码域的不同位置，是需要解决的问题。
基于上述问题，本申请提出了一种零功耗反向散射通信的方案，不同的零功耗终端使用不同的资源，能够解决在小区中大量不同零功耗终端的数据有序区别传输的问题，保证了数据的可靠传输。
在本申请实施例中，蜂窝网络中供能的信号和用于信息传输的信号(触发信号)，可以是两个信号，也可以是一个信号。这两个信号可以不在一个频段发送，也可以在同一个频点发送。可以在某个频段持续或者间歇性的发送的供能信号，是一种连续波(Continuous wave，CW)，例如正弦波。供能的信号和触发信号可以都由蜂窝网络的基站发送，如图7所示。或者，供能信号由专门的节点发送，如图8所示。零功耗终端进行能量采集，零功耗终端获得能量之后，可以进行相应的对应的信号接收，信号反射以及测量等功能。
本申请主要通过基站调度零功耗终端接收数据，反射数据和反射反馈控制信息的时频资源等参数，达成多个终端的复用。
以下通过具体实施例详述本申请的技术方案。
