具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,但是这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
下面首先对本申请涉及的技术内容进行简单描述。
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的信息。
请参考图1,图1为读取器和标签的通信方法示意图,其中,读取器和标签之前具有两条链路(links),一条链路是读取器到标签的链路,一条链路是标签到读取器的链路(反向散射链路),读取器通过读取器到标签的链路向标签发送命令(command)或供能载波信号(wave),目前的方案中,读取器持续向标签发送供能载波信号。标签通过标签到读取器的链路发送反向散射信号。
标签发送反向散射信号的一种简单的实现方式为,当需要发送‘1’时,标签对入射 载波信号进行反向散射,需要发送‘0’时,标签不进行反向散射。
请参考图2,图2为读取器和标签的内部结构示意图。
2、射频识别(Radio Frequency Identification,RFID)中读取器和标签之间的信息传输
请参考图3,其中,对于读取器侧包括以下操作:
a.选取:询问者为后续盘点选取标签群体或为后续认证对标签群体进行加密质询的过程。选取包括选择和挑战命令。
b.盘点:询问者识别标签的过程。询问者通过在四个会话中的一个会话中发送查询命令来开始一轮盘点。一个或多个标签可能会回复。询问器检测到单个标签回复,并从标签中请求协议控制(Protocol Control,PC)、可选扩展协议控制(Extended Protocol Control,XPC)字、电子产品代码(Electronic Product Code,EPC)和CRC-16。一轮盘点一次只能在一个会话中进行。盘点包括多个命令。
c.接入:询问者与单个标签进行交易(读取、写入、验证或以其他方式参与)的过程。在接入之前,询问者对标签进行识别和唯一标识。接入包括多个命令。
读取器操作的指令可以参见表1和表2:
表1
表2


标签的状态参见表3:
表3
现在超高频(Ultra High Frequency,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)后标签响应回应(Reply),即产生一个16比特(bit)的随机数 给读取器。然后读取器将该序列通过ACK指令发给标签后,标签将相关的数据发送给读取器。
请参考图4,图4为标签接收和发送数据的流程示意图。
请参考图5,图5为查询和接入单个标签的流程示意图。
