为了便于更加清晰地理解本申请各实施例，首先对一些相关的技术知识进行如下介绍。
一、反向散射通信(Backscatter Communication，BSC)
反向散射通信是指反向散射通信设备利用其它设备或者环境中的射频信号进行信号调制来传输反向散射通信设备的信息。反向散射通信设备，可以是以下至少一项：
(1)传统的无线射频识别(Radio Frequency Identification，RFID)中的反向散射通信设备，一般是一个标签(tag)，属于无源物联网设备(Passive Internet of Things，Passive-IoT)；
(2)半无源标签(semi-passive tag)，这类tag的下行接收或者上行反射具备一定的方法能力；
(3)具备主动发送能力的标签(active tag)，这类tag可以不依赖对入射信号的反射，向reader发送信息。
图2是现有技术提供的阅读器与标签之间的交互示意图之一，如图2所示，阅读器(reader)向标签(tag)发送命令(command)和连续波(Continuous Wave)，标签向阅读器发送反向散射信号；其中，包括两种连接方式：连接方式1、阅读器至标签；连接方式2、标签至阅读器。
一种简单的实现方式为：当tag需要发送‘1’时，tag对入射载波信号进行反射；当tag需要发送‘0’时，tag对入射载波信号不进行反射。
反向散射通信设备通过调节内部阻抗来控制电路的反射系数Γ，从而改变入射信号的幅度、频率、相位等，实现信号的调制；其中，反射系数Γ采用公式(1)表示：
其中，Z0为天线特征阻抗，Z1为负载阻抗，θ表示相位，T表示周期。
假设入射信号为Sin(t)，则输出信号为Sout(t)，因此，通过合理的控制反射系数可实现对应的幅度调制、频率调制或相位调制。
二、RFID中Reader和Tag之间的信息传输
图3是现有技术提供的Reader和Tag之间的信息传输之意图，如图3所示，阅读器操作指令包括：选择(Select)、盘点(Inventory)和接入(Access)；其中，
a.选择：阅读器为后续盘点选择一个标签，或以密码学的方式质询一个标签以进行后续身份验证的过程。选择包括选择(Select)命令和质询(Challenge)命令。
b.盘点：阅读器识别标签的过程。阅读器通过四个会话中的一个会话发送查询(Query)命令开始一个盘点回合。一个或多个标签可以回复阅读器。阅读器检测到单个标签的回复，并向标签请求协议控制(Protocol Control，PC)、可选扩展协议控制字(Extended Protocol Control，XPC)、电子产品代码(Electronic Product Code，EPC)和循环冗余校验16(Cyclic Redundancy Check-16，CRC-16)。阅读器的每一轮盘点中每次只在一个会话中进行盘点。阅读器由多个命令组成。
c.接入：阅读器与单个标签进行事务处理(读、写、验证，或以其他方式)的过程。阅读器在接入之前，对标签进行单独唯一的标识。接入由多个命令组成。
Reader阅读器操作的指令：
Select：
Inventory：
Access：


Tag标签的状态
现在特高频(Ultra High Frequency，UHF)RFID的协议设计在盘点模式下，要求阅读器发送查询指令(Query)后，标签Tag响应回应(Reply)，即标签产生一个16bit的随机数给阅读器，阅读器将该16-bit序列通过ACK指令发给标签后，标签将相关的数据发送给阅读器。
图4是现有技术提供的阅读器查询和接入单个标签的流程示意图，如图4所示，阅读器发送查询(Query)、调节查询(Adjust)或者重复查询(QueryRep)至标签，标签存在两种可能的结果：1、slot＝0：标签回复RN16；2、slot不等于0：标签不回复。标签向阅读器发送RN16，阅读器应答标签并将相同的RN16发送至标签，标签存在两种可能的结果：1、有效的RN16：标签回复{PC/XPC，EPC}；2、无效的RN16： 标签不回复。阅读器向标签发送随机请求(Req-RN)并将相同的RN16携带在随机请求中，标签存在两种可能的结果:1、有效的RN16：标签回复{handle}；2、无效的RN16：标签不回复。阅读器向标签发送接入命令，其中，每个接入命令使用{handle}作为参数，标签验证handle。
三、session协议
1、协议总结
(1)RFID Gen2协议中Session参数主要是为了方便标签盘点。
(2)每个标签都包含S0至S3总计4种Session，每种Session中又各有A和B两种已盘标记(inventoried flag)，这些标记在不同Session之间不互通。多个阅读器可以使用标签的不同session同时盘点，例如S2的A标记和S3的B标记。
(3)不同session对应标签的标记A或标记B的转换方式是不同的。
2、标签上电时的盘点旗标(inventoried flag)
可以理解为不同Session的flag断电再次充电后的保持情况都是不同的。
(1)S0的flag必定为A。S0的flag只和是否断电有关。
(2)S1的flag可以为A或者B，只要还保持在上一次设定的flag持续时间范围之内，S1的flag就保持之前所设置的flag；如果超出了持续时间(persistence time)，就复原回默认flag A，因为在S1的状态中flag的持续时间并不会自动刷新，即便在一直上电的情况下，还是可能因为超出了持续时间回到默认flag A。S1的flag只和持续时间有关。
(3)S2和S3情况基本一致，即只要一直处于充电状态中，就保持之前设置的flag。但如果中途断电并且断电时间超过标签的持续时间，那么就回到默认flag A。S2和S3的flag与是否断电有关，也和断电后的持续时间有关。
