在本申请实施例中，终端设备需要其他设备，如网络设备为其供能，因此，在本申请实施例中，终端设备可以是零功耗终端，当然也可以是其他需要被供能的任何终端设备，本申请对此不做限制。
示例性地，在零功耗通信系统中，终端设备主要通过网络设备为其供能，下面将对零功耗通信技术的相关技术进行说明：
一、零功耗终端的分类
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：
(1)无源零功耗终端
无源零功耗终端无需内装电池，当无源零功耗终端接近网络设备时，该无源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，该无源零功耗终端的天线通过电磁感应产生感应电流，感应电流驱动该无源零功耗终端的低功耗芯片电路，以实现对前向链路的信号解调工作以及反向散射链路的信号调制等工作。对于反向散射链路，该无源零功耗终端使用反向散射实现方式进行信号的传输。
由此可知，无论是针对前向链路还是反向散射链路，无源零功耗终端都不需要内置电池来驱动低功耗芯片电路，这类终端是一种真正意义的零功耗终端。
此外，无源零功耗终端的射频电路以及基带电路都非常简单，例如无源零功耗终端不需要低噪放(Low Noise Amplifier，LNA)、功放(Power Amplifier，PA)、晶振、模数转换器(Analog-to-Digital Converter，ADC)等器件，因此无源零功耗终端具有体积小、重量轻、价格非常便宜、使用寿命长等诸多优点。
(2)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，可以驱动半无源零功耗终端的低功耗芯片电路，以实现对前向链路信号的解调以及反向散射链路的信号调制等工作。对于反向散射链路，半无源零功耗终端使用反向散射实现方式进行信号的传输。
由此可知，无论是针对前向链路还是反向散射链路，半无源零功耗终端都不需要内置电池来驱动低功耗芯片电路，虽然半无源零功耗终端存在储能单元进行储能，但其能量还是来源于RF能量采集模块采集的无线电能量，因此半无源零功耗终端也是一种真正意义的零功耗终端。
此外，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。
(3)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，该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，以及反向散射链路的信号调制等工作。但对于反向散射链路，该类终端可以使用反向散射实现方式进行信号的传输。因此，该类终端的零功耗主要体现于反向散射链路的信号传输不需要消耗该类终端自身功率，而是使用反向散射的方式。
有源零功耗终端内置的电池可以向低功耗芯片电路供电，以增加有源零功耗终端的读写距离，提高通信的可靠性。因此其可以在一些对通信距离，读取时延等方面要求相对较高的场景得以应用。
二、零功耗通信技术原理
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，这里的零功耗终端可以是上述的半无源零功耗终端。其中网络设备用于向该零功耗终端发送供能信号，下行通信信号以及接收零功耗终端的反向散射信号。该零功耗终端可以包括RF能量采集模块，反向散射通信模块以及低功耗芯片电路。此外，零功耗终端还可具备一个存储器用于存储一些基本信息(如物品标识等)，还可以包括传感器，用于获取环境温度、环境湿度等传感数据。
在本申请实施例中，供能信号用于向零功耗终端供能，以触发零功耗终端工作，因此，该供能信号也被称为触发信号。或者，该供能信号也被称为载波信号。
零功耗通信的关键技术主要包括无线射频能量采集和反向散射通信。
如图3所示，零功耗终端接收网络设备发送的供能信号，通过RF能量采集模块采集能量，进而对低功耗芯片电路进行供能，对供能信号进行调制，并进行反向散射，主要特征如下：
(1)零功耗终端不主动发射信号，通过调制供能信号实现反向散射通信；
(2)零功耗终端不依赖传统的有源功放发射机，同时使用低功耗芯片电路，极大降低硬件复杂度；
(3)结合能量采集可实现免电池通信。
如图4所示，零功耗终端可以利用RF能量采集模块，通过电磁感应实现对空间电磁波能量的采集，进而实现对低功耗芯片电路、传感器等的驱动。
负载调制是零功耗终端经常使用的向网络设备传输数据的方法。负载调制通过对零功耗终端振荡回路的电参数按照数据流的节拍进行调节，使零功耗终端阻抗的大小和相位随之改变，从而完成调制的过程。负载调制技术主要有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，称为负载调制电阻，该电阻按数据流的时钟接通和断开，开关S的通断由二进制数据编码控制。电阻负载调制的电路原理如图5所示。
在电容负载调制中，负载并联一个电容，取代了图5中由二进制数据编码控制的负载调制电阻。
零功耗终端传输的数据，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(Non Return Zero，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、米勒(Miller)编码利差动编码。通俗的说，就是用不同的脉冲信号表示0和1。
如上所述，目前许多通信行业对终端设备的功耗有着较高要求，基于此，零功耗终端的应用成为许多通信行业的关键技术。零功耗终端可以应用在各种场景中，例如：零功耗终端可以设置在物流场景中的货物上，也可以设置在畜牧业农场场景中的动物身上，还可以设置在用户或用户物品上等等。而在这些场景中经常需要定位零功耗终端所在的物品，换句话讲，目前对零功耗终端的定位至关重要。
为了解决上述技术问题，在本申请实施例中，终端设备可以基于第一信号确定终端设备的定位信息，该第一信号 用于向终端设备供能。
应理解的是，本申请技术方案可以应用于如下场景，但不限于此：
场景一，图6为本申请实施例提供的一种通信系统的示意图，如图6所示，网络设备601可以向终端设备602供能，还可以触发终端设备602上报其自身的定位信息，终端设备602可以通过反向散射方式向网络设备601上报其自身的定位信息，以使网络设备601根据该位置信息确定终端设备602的位置信息。
场景二，如图6所示，网络设备603可以向终端设备604供能，还可以触发终端设备602上报其自身的定位信息，终端设备604可以通过反向散射方式向网络设备603上报其自身的定位信息，网络设备603可以将该定位信息反馈给网络设备601，使得网络设备601根据该位置信息确定终端设备604的位置信息，或者，网络设备603根据该位置信息确定终端设备604的位置信息，并将该位置信息反馈给网络设备601。
场景三，如图6所示，网络设备605可以向终端设备606供能，还可以触发终端设备606上报其自身的定位信息，终端设备606可以通过反向散射方式向网络设备601上报其自身的定位信息，网络设备601可以将该定位信息确定终端设备的位置信息。
场景四，如图6所示，网络设备607可以向终端设备608供能，网络设备601可以触发终端设备608上报其自身的定位信息，终端设备608可以通过反向散射方式向网络设备607上报其自身的定位信息，网络设备607可以将该定位信息反馈给网络设备601，使得网络设备601根据该位置信息确定终端设备608的位置信息，或者，网络设备607根据该位置信息确定终端设备608的位置信息，并将该位置信息反馈给网络设备601。
场景五，如图6所示，网络设备609可以向终端设备610供能，网络设备601可以触发终端设备608上报其自身的定位信息，终端设备610可以通过反向散射方式向网络设备601上报其自身的定位信息。换句话讲，在场景五中，网络设备609仅起到供能的作用。
下面将对本申请技术方案进行详细阐述：
图7为本申请实施例提供的一种无线通信方法的流程图，如图7所示，该方法包括如下步骤：
S710：终端设备根据第一信号确定终端设备的定位信息；
S720：终端设备上报定位信息。
需要说明的是，在本申请实施例中，用于向终端设备供能的第一信号可以仅起到供能的作用，这时该第一信号也被称为供能信号，或者，如果该第一信号还可以触发终端设备上报其自身的定位信息，这时该第一信号不仅仅是一个供能信号，可以认为该第一信号是一种特殊的供能信号，比如：具有触发功能的供能信号，例如：该第一信号可以在特定的资源上传输，以通过这种隐式方式表示其是特殊的供能信号。
在一些可实现方式中，第一信号对应于第一信号的发射功率和/或第一信号的空间信息。例如，第一信号、第一信号的相关信号或者相关信道承载第一信号的第一标识和/或第一信号的第二标识；或者，第一信号、第一信号的相关信号或者相关信道隐式携带该第一标识和/或该第二标识；又或者，第一信号、第一信号的相关信号或者相关信道显式或者隐式携带第一信号的第三标识。

在一些可实现方式中，定位信息包括第一信号的第一标识和/或第一信号的第二标识，但不限于此。
在一些可实现方式中，定位信息也可以不携带第一标识和/或第二标识，而是通过隐式的方式表示该第一标识和/或第二标识，例如可以在特定的时域、频域、码域中至少一项发送定位信息，以表示该第一标识和/或第二标识。
应理解的是，第一标识与第一信号的发射功率相关可以被理解为：该第一标识用于标识该第一信号的发射功率，或者该第一标识用于标识该发射功率对应的功率发射范围，该功率发射范围也被称为功率发射区域、功率发射半径、发射功率半径、发射功率范围或者发射功率区域等，本申请对此不做限制。
应理解的是，第一信号的第二标识对应于第一信号的空间信息可以被理解为：该第二标识用于标识第一信号的空间信息。
在一些可实现方式中，第一信号的空间信息包括以下至少一项，但不限于此：第一信号的角度、坐标、方向。
应理解的是，当第一信号具有空间信息时，表示该第一信号是区域性的信号。
在一些可实现方式中，第一网络设备可以发送多个信号，多个信号用于供能，多个信号包括上述第一信号。
在一些可实现方式中，多个信号中任意两个信号对应不同的发射功率和/或空间信息。例如，如图8所示，这里的信号1～4的功率发射范围分别是Z1、Z2、Z3和Z4，它们均不同，即表示它们的发射功率均不同。如图9所示，每个椭圆表示一个信号的发射方向区域，这些发射方向区域的方向，角度、坐标至少一项不同。类似的，如图10所示，信号1～8的发射方向区域Z1～Z8均不同。如图11所示，可以定义若干个区域Zij,其中i取值为1-4，代表发射功率从低到高，y取值为1-8，代表不同的发射方向按区域。示例性地，Z18与Z28具有相同的发射方向区域，但是对应不同的发射功率。Z18与Z11具有不同的发射方向区域，但是对应相同的发射功率。Z18与Z21具有不同的发射方向区域以及对应不同的发射功率。
在一些可实现方式中，如果上述多个信号具有不同的发射功率，那么这些信号是按照发射功率从低到高的顺序发送的，或者，按照发射功率从高到低的顺序发送的，本申请对此不做限制。
在一些可实现方式中，如果上述多个信号存在发射功率不同的信号，那么这些信号是按照发射功率从低到高的顺序发送的，或者，按照发射功率从高到低的顺序发送的，本申请对此不做限制。
在一些可实现方式中，在一定的发射功率下，第一网络设备可以分时或者同时发送区域性的信号，本申请对此不做限制。
应理解的是，在本申请实施例中，可以根据定位需求设置多个信号的数量、它们分别对应的发射方向区域、发射功率中的至少一项，总之，本申请对多个信号的数量、它们分别对应的发射方向区域、发射功率不做限制。
在一些可实现方式中，多个信号是分时或者同时发送的，例如：第一网络设备可以扫描式的分时发送这些信号，也可以同时发送这些信号。
在一些可实现方式中，多个信号的发送方式可以是第二网络设备或者第一网络设备配置的，本申请对此不做限制。
在一些可实现方式中，多个信号中任意两个信号对应的频域资源和/或码域资源不同，例如：在多个信号是同时发送的情况下，多个信号中任意两个信号对应的频域资源和/或码域资源不同；或者，在多个信号是分时发送的情况下，多个信号中任意两个信号对应的频域资源和/或码域资源不同。
在一些可实现方式中，第二网络设备向第一网络设备发送第二控制信息。其中，第二控制信息用于控制第一网络设备发送第一信号，第二网络设备与第一网络设备具有关联关系。
在一些可实现方式中，第二网络设备是用于控制该第一网络设备的设备，该第二网络设备还可以控制更多的网络设备，例如：如图6所示，网络设备603、网络设备605和网络设备607的第一信号的发送都可以由网络设备601控制。
示例性地，在如图6所示的场景二中，网络设备601可以向网络设备603发送第二控制信息，以控制网络设备603发送第一信号。在如图6所示的场景三中，网络设备601可以向网络设备605发送第二控制信息，以控制网络设备605发送第一信号。在如图6所示的场景四中，网络设备601可以向网络设备607发送第二控制信息，以控制网络设备607发送第一信号。在如图6所示的场景五中，网络设备601可以向网络设备609发送第二控制信息，以控制网络设备609发送第一信号。
在一些可实现方式中，上述第一标识和/或第二标识携带在以下任一项中：第一信号、第一信号相关的信号、第一信号相关的信道。
应理解的是，第一信号相关的信号指的是与第一信号具有关联关系的信号，例如：该信号是与第一信号具有相同的时域、频域、码域资源中至少一项的信号，本申请对此不做限制。
应理解的是，第一信号相关的信道指的是与第一信号具有关联关系的信道，例如：该信道可以是承载该第一信号的信道，或者是该信道的相邻信道，本申请对此不做限制。
在一些可实现方式中，第一网络设备获取到终端设备的定位信息之后，可以根据该定位信息确定终端设备的位置信息。或者，根据该定位信息以及上述多个信号的关联关系确定终端设备的位置信息。
在一些可实现方式中，若定位信息包括第一标识，则第一网络设备根据第一发射功率范围和第二发射功率范围确定终端设备的位置信息；若定位信息包括第二标识，则第一网络设备根据第一信号的空间信息确定终端设备的位置信息；若定位信息包括第一标识和第二标识，则第一网络设备根据第一发射功率范围、第二发射功率范围和空间信息确定终端设备的位置信息；其中，第一发射功率范围是第一信号的发射功率范围，第二发射功率范围是第二信号的发射功率范围；第二信号满足如下条件，但不限于此：第二信号的发射功率范围小于第一信号的发射功率范围；第二信号的发射功率范围与第一信号的发射功率范围相邻；第一网络设备未接收到基于第二信号的终端设备的第二定位信息。
应理解的是，上述多个信号的关联关系可以包括：第一信号与第二信号的关联关系。实际上，若定位信息包括第一标识，或者，包括第一标识和第二标识，那么第一网络设备均需要结合定位信息和第一信号与第二信号的关联关系来确定终端设备的位置信息。
示例性地，如图8所示，网络设备发送了4种不同发射功率的信号1～4，对应的供能信号的覆盖半径为Z1-Z4。网络设备在发送这4个信号时，通过终端设备上报的定位信息来确定该定位信息是哪个信号对应的定位信息，从而确定终端设备在该信号对应的覆盖范围内。例如，如图8中的终端T1，当网络设备发送覆盖半径为Z1的信号1时未收到终端T1反馈的定位信息，在发送覆盖半径为Z2的信号2时收到终端T1反馈的定位信息，则网络设备可以判断终端T1位于距离网络设备为Z1和Z2之间的环状区域内。类似的，终端T2位于距离网络设备为Z3和Z4之间的环状区域内。
示例性地，如图10所示，网络设备发送不同的区域性的信号1～8，覆盖半径分别是Z1～Z8，终端T1在覆盖半径Z8内，并向网络设备反馈定位信息，则网络设备可以确定终端T1所在区域是Z8；终端T2在覆盖半径Z6内，并向网络设备反馈定位信息，则网络设备可以确定终端T2所在区域是Z6。
示例性地，如图11所示，可以定义若干个区域Zij,其中i取值为1-4，代表发射功率从低到高，y取值为1-8，代表不同的发射方向按区域。其中，网络设备在收到该定位信息后，可以结合多个信号的扫描顺序和多个信号的功率覆盖范围以及发射方向区域之间的关系可以确定终端设备的位置信息。例如，多个信号按照发射功率从低到高的顺序扫描，在发射发射功率索引为1的信号时，各个方向的信号没有激活终端设备反馈其定位信息。在发射发射功率索引为2，发射方向区域索引为8的信号时，该信号激活了终端设备反馈其定位信息，基于此，网络设备可以确定该终端设备位于区域Z28中。
在一些可实现方式中，第一网络设备在获取到终端设备的位置信息之后，第一网络设备可以向第二网络设备发送终端设备的位置信息。
示例性地，在如图6所示的场景二中，网络设备603在获取到终端设备604的位置信息之后，其可以将终端设备604的位置信息发送给网络设备601。在如图6所示的场景四中，网络设备607在获取到终端设备608的位置信息之后，其可以将终端设备608的位置信息发送给网络设备601。

示例性地，在如图6所示的场景三中，终端设备606可以将其自身的定位信息发送给网络设备601。在如图6所示的场景五中，终端设备610可以将其自身的定位信息发送给网络设备601。
在一些可实现方式中，第一网络设备在获取到终端设备的定位信息之后，第一网络设备可以向第二网络设备发送终端设备的定位信息，以使第二网络设备根据该定位信息确定终端设备的位置信息。其中，第二网络设备确定终端设备的位置信息可以参考上文第一网络设备确定终端设备的位置信息的方法，本申请对此不再赘述。
示例性地，在如图6所示的场景二中，网络设备603在获取到终端设备604的定位信息之后，其可以将终端设备604的定位信息发送给网络设备601，以使网络设备601根据该定位信息确定终端设备604的位置信息。在如图6所示的场景四中，网络设备607在获取到终端设备608的定位信息之后，其可以将终端设备608的定位信息发送给网络设备601，以使网络设备601根据该定位信息确定终端设备608的位置信息。
需要说明的是，在上述可实现方式中，定位信息可以包括：第一标识和/或第二标识。也就是说，第一网标识和第二标识是两个独立的标识。实际上，定位信息还可以是如下形式的信息，但不限于此：
在一些可实现方式中，定位信息包括第一信号的第三标识。
