图1示出了零功耗通信系统100的示意图，零功耗通信系统100包括网络设备120和零功耗终端140。
网络设备120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。零功耗终端140包含能量采集模块141，反向散射通信模块142以及低功耗计算模块143。能量采集模块141可以采集空间中的无线电波携带的能量，用于驱动零功耗终端140的低功耗计算模块143和实现反向散射通信。零功耗终端140获得能量后，可以接收网络设备120的控制信令，并根据控制信令基于后向散射的方式向网络设备120发送数据。发送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140还可以包括传感器模块144和存储器145。传感器模块144可以包括各类传感器，零功耗终端140可以基于零功耗机制将各类传感器采集的数据上报。存储器145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。
零功耗终端自身不需要电池，同时采用低功耗计算模块可实现简单的信号解调，解码或编码，调制等简单的运算工作，因此零功耗模块仅需要极简的硬件设计，使得零功耗设备成本很低、体积很小。
接下来，对零功耗通信的关键技术进行介绍：
·射频能量采集(Radio Frequency Power Harvesting)
图2示出了射频能量采集的原理图。射频能量采集是基于电磁感应原理，利用射频模块RF通过电磁感应，并与保持并联关系的电容C、负载电阻R L进行连接，实现对空间电磁波能量的采集，获得驱动零功耗终端工作所需的能量，比如：用于驱动低功耗解调模块、调制模块、传感器和内存读取等。因此，零功耗终端无需传统电池。
·反向散射通信(Back Scattering)
图3示出了反向散射通信过程的原理图。零功耗终端140接收网络设备120发送模块(Transmit，TX)121使用异步映射规程(Asynchronous Mapping Procedure，AMP)122发送的无线信号载波131，并对无线信号载波131进行调制，使用逻辑处理模块141加载需要发送的信息，并使用能量采集模块142采集射频能量。零功耗终端140使用天线143辐射调制后的反射信号132，这个信息传输过程称为反向散射通信。网络设备120接收模块(Receive，RX)123使用低噪声放大器(Low Noise Amplifier，LNA)124接收调制后的反射信号132。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140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，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。图4示出了电阻负载调制的原理图。在电阻负载调制中，负载电阻R L并联第三电阻R 3，基于二进制编码的控制的开关S实现接通或断开，第三电阻R 3的通断会导致电路上的电压产生变化，负载电阻R L与第一电容C 1保持并联的连接关系，负载电阻R L与第二电阻R 2保持串联的连接关系，第二电阻R 2与第一电感L 1保持串联的连接关系。第一电感L 1与第二电感L 2之间耦合，第二电感L 2与第二电容C 2保持串联的连接关系。可以实现幅度键控调制(Amplitude Shift Keying，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(Frequency Shift Keying，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。
零功耗终端借助负载调制的方式，对来波信号进行信息调制，实现了反向散射通信的过程。零功耗终端具有显著的优点：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；终端不需要主动产生高频信号，因此不需要高频晶振；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。
接下来，对零功耗通信的编码方式进行介绍：
图5示出了编码方式的示意图。电子标签传输的数据，可以使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(Not Return to Zero，NRZ)编码、曼彻斯特(Manchester)编码、单极性归零(Unipolar Return to Zero，URZ)编码、差动双相(Differential Binary Phase，DBP)编码、米勒(Miller)编码和差动编码。即可以使用不同的脉冲信号表示0和1。
·NRZ编码；反向不归零编码用高电平表示二进制“1”，低电平表示二进制“0”，图5中NRZ编码示出了使用NRZ方法编码二进制数据：101100101001011的电平示意图。
·曼彻斯特编码；曼彻斯特编码也被称为分相编码(Split-Phase Coding)。在曼彻斯特编码中，二进制数值由该位长度内半个位周期时电平的变化(上升或下降)表示，在半个位周期时的负跳变表示二进制“1”，半个位周期时的正跳变表示二进制“0”，数据传输的错误是指在当多个电子标签同时发送的数据位有不同值时，接收的上升边和下降边互相抵消，导致在整个位长度内是不间断的载波信号。曼彻斯特编码在位长度内，不可能存在没有变化的状态。读写器利用该错误就可以判定碰撞发生的具体位置。曼彻斯特编码有利于发现数据传输的错误，在采用载波的负载调制或者反向散射调制时，通常用于从电子标签到读写器的数据传输。图5中曼彻斯特编码示出了使用曼彻斯特方法编码二进制数据：101100101001011的电平示意图。
·URZ编码；单极性归零编码在第一个半个位周期中的高电平表示二进制“1”，而持续整个位周期内的低电平信号表示二进制“1”，图5中URZ编码示出了使用URZ方法编码二进制数据：101100101001011的电平示意图。
·DBP编码；差动双相编码在半个位周期中的任意的边沿表示二进制“0”，没有边沿表示二进制“1”，此外，在每个位周期开始时，电平都要反相。对接收器来说，位节拍比较容易重建。图5中DBP编码示出了使用DBP方法编码二进制数据：101100101001011的电平示意图。
·米勒编码；米勒编码在半个位周期内的任意边沿表示二进制“1”，而经过下一个位周期中不变的电平表示二进制“0”。位周期开始时产生电平交变，对接收器来说，位节拍比较容易重建。图5中米勒编码示出了使用米勒方法编码二进制数据：101100101001011的电平示意图。
·差动编码；差动编码中，每个要传输的二进制“1”都会引起信号电平的变化，而对于二进制“0”，信号电平保持不变。
接下来，对零功耗终端进行详细介绍：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如下类型：
·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时，零功耗终端处于网络设备天线辐射形成的近场范围内，示例性的，网络设备是射频识别技术(Radio Frequency Identification，RFID)系统的读写器。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，以及后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。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，例如不需要低噪声放大器(Low Noise Amplifier，LNA)、功率放大器(Power Amplifier，PA)、晶振、模数转换器(Analog to Digital Converter，ADC)等器件，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不安装常规电池，可使用射频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中，示例性的，储能单元是电容。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，以及后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。
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，工作中使用的电容储存的能量来源于射频能量采集模块采集的无线电能量，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，比如：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；
有源零功耗终端可以内置电池。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，以及后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。有源零功耗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，使用了反向散射的方式。在有源零功耗终端中，内置电池向RFID芯片供电，增加标签的读写距离，提高通信的可靠性。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。
随着通信行业的发展，特别是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，可以充实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零功耗通信技术，如RFID技术，并在此基础上进行延伸，以适用于蜂窝物联网。

步骤320：使用第一上行资源向网络设备发送上行数据。
示例性的，上行数据用于响应触发指令，实现与网络设备的通信。上行数据中通常包括零功耗终端的相关信息，比如：零功耗终端的终端标识。但也不排除不包括零功耗终端的相关信息的情况。本实施例对零功耗终端向网络设备发送的上行数据的种类和内容不作出任何限制。
综上所述，本实施例提供的方法，通过由零功耗终端在网络设备配置的至少两个上行资源中，选择出第一上行资源发送上行数据，使得不同的零功耗终端所选择的第一上行资源尽量不同，从而降低了多个零功耗终端发生上行冲突的可能性，提高零功耗通信的上行成功率。

需要说明的是，在实施例中，三种实现方式中的任意一种均可以实现零功耗终端对第一上行资源的选择，三种实现方式可以分别实施，与其他步骤重新组合成为新的实施例。
实现方式一：零功耗终端在满足触发条件的情况下，基于零功耗终端的终端标识和上行资源的数量，选择第一上行资源；
