图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、无线局域网(Wireless Local Area Networks，WLAN)接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。
为使本领域技术人员能够更好地理解本申请实施例，先进行如下说明。
1、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自己信息。反向散射通信设备，可以是：
(1)传统射频识别(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IoT设备(Passive-IoT)；
(2)半无源(semi-passive)的tag，这类tag的下行接收或者上行反射具备一定的放大能力；
(3)具备主动发送能力的tag(active tag)，这类终端可以不依赖对入射信号的反射向基站(gNB)或阅读器(reader)发送信息。
一种简单的实现方式为，tag需要发送“1”时，tag对入射载波信号进行反射，tag需要发送“0”时不进行反射。
反向散射通信设备通过调节其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。其中信号的反射系数可表征为：
其中，Z0为天线特性阻抗，Z1是负载阻抗。假设入射信号为Sin(t)，则输出信号为因此，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。
2、RFID中gNB/reader和Tag之间的信息传输；
a、选择(Select)
读取器为后续盘点选择标签群或对标签群进行加密以进行后续认证的过程。选择包括选择和质询命令；
b、盘点(Inventory)
读取器识别标签的过程。读取器通过在四个会话中的一个会话中发送查询命令来开始盘点循环。一个或多个标签可能回复。读取器检测单个标签应答，并请求协议控制(Protocol Control，PC)，可选的请求扩展协议控制(Extended Protocol Control，XPC)字、电子产品代码(Electronic Product Code，EPC)和16比特循环冗余效验码(16 bit Cyclic Redundancy Check，CRC-16)。盘点循环一次只运行一个会话。盘点包含多个命令。
c、接入(Access)
读取器与单个标签进行交易(读取、写入、鉴权或以其他方式参与)的过程，在接入之前，读取器对标签进行单独识别，接入包括多个命令。
Reader读取器操作的指令如表1所示，操作类型如表2所示。
表1

表2


Tag标签的状态如表3所示。
表3

现在超高频射频识别(UHF RFID)的协议设计在盘点模式下，要求读取器发送查询指令(Query)后标签(Tag)响应回应(Reply)，即产生一个16-bit的随机数给读取器。然后读取器将该序列通过ACK指令发给Tag后，Tag将相关的数据发送给阅读器。
3、backscatter通信应用场景
应用场景1:网络侧设备(如基站)发送连续波(Continuous Waves，CW)和信令并接收tag的反射信号。
应用场景2：终端发送CW和信令并接收tag的反射信号。
应用场景3：网络侧设备发送CW和信令给Tag；终端接收Tag发送的反向散射信息。
应用场景4：终端发送CW和信令给Tag，网络侧设备接收Tag的反向散射信息。
上述基站的类型包括但不限于：集成接入回传(Integrated Access and Backhaul，IAB)站(IAB node)，中继器(repeater)，杆站(Pole station)，例如，上述中继器可以是网络控制中继器(network controlled repeater)。
