为便于理解本申请实施例的技术方案，对本申请的相关技术进行说明。
一、零功耗通信
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。
1、射频能量采集(RF Power Harvesting)
如图3所示，能量采集模块(或称，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。
2、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。
3、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如下类型：
1、无源零功耗终端
零功耗终端(如RFID系统的标签)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。
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。
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，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。
二、蜂窝无源物联网
随着5G行业应用的增加，连接物的种类和应用场景越来越多，对通信终端的成本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。
在零功耗通信中，零功耗终端需要采集网络设备发送的无线电波获得能量后才可以驱动自身进行工作。随着工业的发展，接入网络的设备数量激增，应用在蜂窝物联网系统中的零功耗设备的数量也将十分巨大。如果多个终端设备同时将数据传输给网络设备，会造成数据的碰撞，导致网络设备不能获取各个终端设备的数据。因此，如何实现零功耗终端的防碰撞处理是一项亟需解决的问题。

在一些实施例中，终端设备的标识信息包括多个比特，可以根据所述多个比特的特征位的取值确定该终端设备所属的用户组。即，同一用户组中的所有终端设备的标识信息的特征位的取值满足相同的约束条件。因此，终端设备可以根据标识信息的特征位的取值结合用户组的约束条件，确定终端设备所属的用户组。
应理解，在本申请实施例中，终端设备可以直接根据特征位的取值确定终端设备所属的用户组，或者，也可以对该特征位的取值进行处理，例如，模2加(或者说，异或)，根据处理后的结果确定终端设备所属的用户组，本申请对此不作限定。

作为示例，如图8所示，特征位(p2p4p7)的取值{X1,X2,X3,X4,X5,X6,X7,X8}分别对应{用户组1,用户组2,…,用户组8}。即用户组k对应用户ID约束k，其中，用户ID约束k可以表达为：V＝k-1，其中，k＝1,2,…,8，V表示用户组k中的终端设备的标识信息的特征位p2p4p7的取值。
在另一些实施例中，特征位的不同取值范围对应不同的用户组。因此，终端设备可以根据标识信息的特征位的取值所属的范围，确定该终端设备所属的用户组。
换言之，特征位的取值的不同阈值可以对应不同的用户组，因此，终端设备可以根据标识信息的特征位的取值所对应的阈值，确定该终端设备所属的用户组。
例如，如图9所示，终端设备的标识信息包括8比特(p1～p8)，取值范围00000000～11111111，可以取该8比特中的p2，p4和p7作为特征位，进一步根据该三个比特按照顺序组合(p2p4p7)之后的取值结合多个阈值(例如三个阈值)确定对应的用户组。该三个阈值为{Y1,Y2,Y3}，其中，Y1为010，Y2为100，Y3为110。

在另一些实施例中，终端设备的标识信息包括多个比特，可以将所述多个比特的部分或全部比特划分为多个比特组，进一步提取每个比特组的特征位，根据该每个比特组的特征位确定终端设备所属的用户组。
可选地，每个比特组包括的比特可以是连续的，或者，也可以是不连续的，每个比特组包括的比特数可以相同，或者也可以不同。
应理解，本申请实施例并不限定提取每个特征组中的特征位的具体方式，作为示例，提取每个比特组的特征位可以包括：从每个比特组中提取部分比特作为特征位，或者，可以是对每个比特组进行处理，例如模2加，得到每个比特组的特征位。
可选地，提取每个比特组的特征位后，将该多个比特组的特征位组合得到该终端设备的标识信息的目标特征位，进一步可以根据该目标特征位确定终端设备所属的用户组。例如，根据该目标特征位和用户组对应的约束条件，确定该终端设备所属的用户组。
应理解，在本申请实施例中，可以直接根据目标特征位的取值确定终端设备所属的用户组，或者，也可以对该目标特征位的取值进行处理，例如，模2加，根据处理后的结果确定终端设备所属的用户组，本申请对此不作限定。
作为一个示例，目标特征位的不同取值对应不同的用户组。因此，终端设备根据标识信息的目标特征位的取值可以直接确定该终端设备所属的用户组。
例如，如图10所示，终端设备的标识信息包括9比特(p1～p9)，取值范围000000000～111111111。
将该9比特分为3个比特组，例如，p1～p3为第一比特组，p4～p6为第二比特组，p7～p9为第三比特组，进一步提取每个比特组的特征位，例如，对第一比特组进行模2加处理得到特征为t1，对第二比特组进行模2加处理得到特征为t2，对第三比特组进行模2加处理得到特征为t3。将该三个特征位组合得到目标特征位t1t2t3。然后根据该目标特征位的取值确定终端设备所属的用户组。该目标特征位(t1t2t3)的取值集合为{X1,X2,X3,X4,X5,X6,X7,X8}，其中，X1为000，X2为001，X3为010，X4为011，X5为100，X6为101，X7为110，X8为111。
作为示例，如图10所示，目标特征位(t1t2t3)的取值{X1,X2,X3,X4,X5,X6,X7,X8}分别对应{用户组1,用户组2,…,用户组8}。即用户组k对应用户ID约束k，其中，用户ID约束k可以表达为：W＝k-1，其中，k＝1,2,…,8，W表示目标特征位t1t2t3的取值。
作为另一示例，目标特征位的不同取值范围对应不同的用户组。因此，终端设备可以根据标识信息的目标特征位的取值所属的范围，确定该终端设备所属的用户组。
换言之，目标特征位的取值的不同阈值可以对应不同的用户组，因此，终端设备根据标识信息的目标特征位的取值所对应的阈值，确定该终端设备所属的用户组。
例如，如图11所示，终端设备的标识信息包括9比特(p1～p9)，取值范围000000000～111111111。
将该9比特分为3个比特组，例如，p1～p3为第一比特组，p4～p6为第二比特组，p7～p9为第三比特组，进一步提取每个比特组的特征位，例如，对第一比特组进行模2加处理得到特征为t1，对第二比特组进行模2加处理得到特征为t2，对第三比特组进行模2加处理得到特征为t3。将该三个特征位组合得到目标特征位t1t2t3。根据目标特征位t1t2t3的取值结合多个阈值(例如三个阈值)确定对应的用户组。该三个阈值为{Z1,Z2,Z3}，其中，Z1为010，Z2为100，Z3为110。
作为示例，如图11所示，目标特征位t1t2t3的不同取值范围：W＜Z1，Z1≤W＜Z2，Z2≤W＜Z3，W≥Z3，分别对应{用户组1,用户组2,用户组3,用户组4}，其中，W表示目标特征位t1t2t3的取值。即用户组1对应用户ID约束1：W＜Z1；用户组2对应用户ID约束2：Z1≤W＜Z2；用户组3对应用户ID约束3：Z2≤W＜Z3；用户组4对应用户ID约束4：W≥Z3。
作为又一示例，目标特征位t1t2t3的不同取值范围：W≤Z1，Z1＜W≤Z2，Z2＜W≤Z3，W＞Z3，分别对应{用户组1,用户组2,用户组3,用户组4}，其中，W表示目标特征位t1t2t3的取值。即用户组1对应用户ID约束1：W≤Z1；用户组2对应用户ID约束2：Z1＜W≤Z2；用户组3对应用户ID约束3：Z2＜W≤Z3；用户组4对应用户ID约束4：W＞Z3。
在一些实施例中，如图10和图11所示，对第一特征组进行模2加处理得到特征位t1可以包括：
在第一比特组中的比特位的取值为以下组合时，t1＝0:
p1＝0，p2＝0，p3＝0；p1＝0，p2＝1，p3＝1；p1＝1，p2＝0，p3＝1；p1＝1，p2＝1，p3＝0。
在第一比特组中的比特位的取值为其他取值的组合时，t1＝1。
类似地，对第二特征组进行模2加处理得到特征位t2，第三特征组进行模2加处理得到特征位t3的处理方式类似，为了简洁，这里不再赘述。
