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阅读器操作的指令如下表1所示：
表1
Select指令如下表2所示：
表2
Inventory指令如下表3所示：
表3
Access指令如下表4所示：
表4


Tag标签的状态如下表5所示：
表5
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。

具体地，第三控制命令为第二设备基于第一设备发送的RN发送的反馈命令，RN用于指示第一设备的能力，反馈命令用于指示支持目标设备能力的设备执行第一行为。
需要说明的是，本申请中的第一控制命令和第二控制命令分别只是指代相同功能的命令，并不具体限定第一控制命令和第二控制命令的具体命名和实现方式。
实际中，在第一设备接收第二设备发送的第一消息后，第一设备根据第一消息确定或执行第一行为；其中，第一行为包括控制第一设备的状态，和/或，反馈与第一设备的能力相关的信息。

下面对本申请实施例中第一设备基于所述第一消息，确定或执行第一行为的具体实现方式进行说明。
可选地，上述步骤502的具体实现方式包括以下步骤：
步骤1)在所述第一消息包括所述第一控制命令、所述第一指示及所述第二控制命令中任一项的情况下，所述第一设备基于所述第一消息，确定所述目标设备能力；
具体地，在第一消息包括第一控制命令、第一指示及第二控制命令中任一项的情况下，第一设备可以根据第一消息，确定第二设备指示的目标设备能力。
步骤2)所述第一设备基于所述目标设备能力及所述第一设备的能力，确定或执行所述第一行为。
具体地，第一设备在确定第二设备指示的目标设备能力之后，根据目标设备能力和第一设备的能力，可以确定或执行第一行为。
本申请实施例提供的指示方法中，在第一消息包括第一控制命令、第一指示及第二控制命令中任一项的情况下，第一设备根据第一消息确定目标设备能力，再根据目标设备能力和第一设备的能力，确定或执行第一行为，从而使得第二设备能够根据与目标设备能力匹配的第一设备的第一行为对第一设备进行盘点并进行管理。
可选地，上述步骤1)的具体实现方式包括以下至少一项：
方式a)、在所述第一控制命令中包括第三信息的情况下，所述第一设备基于所述第三信息，确定所述目标设备能力；所述第三信息用于直接指示所述目标设备能力；
具体地，在第一控制命令中包括第三信息的情况下，第一设备可以基于第三信息，确定目标设备能力；例如，第三信息用于指示选择支持ASK调制能力的设备，则第一设备可以基于第三信息确定支持ASK调制能力的第一设备，则支持ASK调制能力的第一设备可以进入盘点状态。
第一控制命令用于选取支持目标设备能力的设备；例如，第一控制命令为select命令。第二控制命令用于指示支持目标设备能力的设备启动一次盘点；例如，第二控制命令为query命令。需要说明的是，本申请中的第一控制命令和第二控制命令分别只是指代相同功能的命令，并不具体限定第一控制命令和第二控制命令的具体命名和实现方式。
在同一种场景下部署了不同调制类型(ASK/OOK调制、FSK调制和PSK调制)的tag，而select命令中并不包含调制方式的指示，因此，调制方式的指示信息只能在query命令中指示；其中，具体实现方式为select命令中不区分调制方式，reader使用select命令同时选择FSK调制和OOK调制的tag，reader再使用query命令进一步指示调制方式和Q值，则对于支持reader指示的目标调制方式的tag的slot计数器(slot counter)可以生成随机数，进一步接收query命令盘点；对于不支持该reader指示的目标调制方式的tag，则该tag保持静默，等待接收到query命令中指示的目标调制方式时再进入盘点流程。
方式b)、第一设备基于第一映射关系以及所述第一控制命令中的循环冗余校验(Cyclic Redundancy Check，CRC)类型，确定所述目标设备能力；所述第一映射关系包括设备能力与CRC类型的映射关系；
具体地，第一映射关系包括设备能力与CRC类型的映射关系，则第一设备可以根据第一映射关系以及第一控制命令中的CRC类型，确定目标设备能力；例如，第一类设备使用select命令中的第一类CRC类型加扰，第二类设备使用select命令中的第二类CRC类型加扰，第N类设备使用select命令中的第N类CRC类型加扰，从而确定目标设备能力。
方式c)、第一设备基于第二映射关系以及所述第一指示所指示的session类型，确定所述目标设备能力；所述第二映射关系包括设备能力与session类型的映射关系；
需要说明的是，在RFID Gen2协议中session参数主要是为了方便第一设备盘点，第一设备中的每个设备均包含S0、S1、S2和S3等4种session。不同能力的第一设备关联不同的session类型，可以实现第二设备在盘点过程中通过session类型选择出目标设备能力的第一设备。
具体地，第二映射关系包括设备能力与session类型的映射关系，第二映射关系包括：
a)一对一，即每种能力的设备关联一个session类型；例如，active tag关联S0，semi-passive tag关联S1，passive tag关联S2；第二设备在盘点时，可以通过确定的session类型实现盘点目标设备能力的第一设备。
图6是本申请实施例提供的一种能力的tag关联一个session类型的示意图，如图6所示，有源标签(active tag)关联S0，半无源标签(semi-passive tag)关联S1，无源标签(passive tag)关联S2，active tag、semi-passive tag和passive tag均与S3不关联。因此，当tag的类型数量少于session类型数量时，未被关联的session类型可以采用缺省的方式，或者一种tag类型可以关联多个session类型，此时变成一对多关联关系。当tag类型的数量多于session类型时，现有协议中的session种类(4种session)不足以满足一对一的关联关系，需要扩展session类型，即session类型的种类可以扩展为S0至Sm，m至少大于或等于满足一对一关联关系下的session类型的种类数量，例如，tag类型的数量为8，现有协议中的session种类为4，若采用一对一关联关系，则需要将session类型由4种扩展为8种session类型，即扩展为S0至S7，此时m>＝7。
b)多对一，即多种能力的设备关联一个session类型；例如，active tag关联S0，semi-passive和passive tag均关联S1；
c)一对多，即一种能力的设备关联多个session类型；例如，active tag关联S0，semi-passive关联S1，passive tag关联S1和S2；
d)多对多，即多种能力的设备关联多个session类型；例如，active tag关联S0，semi-passive和passive tag同时关联S1和S2。
实际中，第一设备可以基于第二映射关系以及第一指示所指示的session类型，确定目标设备能力；例如，第一指示所指示的session类型为S0，第二映射关系为一对一，则第一设备可以基于第二映射关系和S0，确定目标设备能力为active tag。
可选地，所述第一映射关系由网络配置或协议预定义；和/或，所述第二映射关系由网络配置或协议预定义。
方式d)、在所述第二控制命令中包括第四信息的情况下，所述第一设备基于所述第四信息，确定所述目标设备能力；所述第四信息用于直接指示所述目标设备能力。
具体地，在第二控制命令中包括第四信息的情况下，第一设备可以基于第四信息，确定目标设备能力；例如，第四信息同时指示第一设备能力为指示传输速率为 MHz级别和Q值，则支持MHz级别的第一设备生成随机数，对于支持除MHz级别之外的传输速率的第一设备保持静默，该第一设备的计数器设置为特定值(例如1111)，等待接收到第二控制命令中指示的能力时再进入盘点流程。

可选地，上述步骤2)的具体实现方式包括以下至少一项：
方式1、在所述第一设备的能力与所述目标设备能力匹配的情况下，所述第一设备确定或执行以下至少一项：设置或改变所述第一设备的计数器数值；设置或改变所述第一设备的盘点状态；向所述第二设备反馈所述第一设备的能力；向所述第二设备反馈所述第一信息；
具体地，在第一设备的能力与目标设备能力匹配的情况下，即与目标设备能力匹配的第一设备可以确定或执行以下至少一项：设置或改变第一设备的计数器数值；设置或改变第一设备的盘点状态；向第二设备反馈第一设备的能力；向第二设备反馈第一信息。
方式2、在所述第一设备的能力与所述目标设备能力不匹配的情况下，所述第一设备确定或执行以下至少一项：向第二设备反馈所述第一设备的能力；向第二设备反馈所述第二信息。
具体地，在第一设备的能力与目标设备能力不匹配的情况下，即与目标设备能力不匹配的第一设备可以确定或执行以下至少一项：向第二设备反馈第一设备的能力；向第二设备反馈第二信息。
本申请实施例提供的指示方法中，在第一设备的能力与目标设备能力匹配的情况下，第一设备确定或执行以下至少一项：设置或改变第一设备的计数器数值；设置或改变第一设备的盘点状态；向第二设备反馈第一设备的能力；向第二设备反馈第一信息；在第一设备的能力与目标设备能力不匹配的情况下，第一设备确定或执行以下至少一项：向第二设备反馈第一设备的能力；向第二设备反馈第二信息，从而使得第二设备能够根据第一设备确定或执行的第一行为对第一设备进行盘点并进行管理。
可选地，第三控制命令为第二设备基于第一设备发送的RN发送的反馈命令，RN用于指示第一设备的能力，反馈命令用于指示支持目标设备能力的设备执行第一行为。反馈命令也可以称为RN反馈指示。
RN反馈指示与目标设备能力相关联，具体指示方式可以包括以下至少一项：
1)RN对应的数值范围，用于指示所述第一设备的能力；
例如RN中特定的bit映射到特定的设备能力。
2)RN中的目标比特位，用于指示所述第一设备的能力。
例如RN中预留m-bit信息指示设备能力。
需要说明的是，UHF RFID的协议设计在盘点模式下，要求reader发送查询指令(Query)后，tag响应回应(Reply)，即tag产生一个16bit的随机数给reader，然后reader将该16bit序列通过ACK指令发给tag后，tag将相关的数据发送给reader，具体实现方式如图4所示。
在本申请实施例中，第一设备产生的16bit RN可以指示第一设备的能力，具体指示方式可以包括显示指示和隐式指示两种，分别说明如下：
1)隐式指示。例如，A bit指示active tag，B bit指示semi-passive tag，C bit指示passive tag，其中，A、B和C三者之和为16。假设16bit RN中的0bit至4bit预先分配给active tag，active tag产生的随机数的范围是0至15，则reader只有在接收到的RN小于或者等于15时，reader才会反馈ACK至active tag，active tag在接收到reader反馈的ACK后才会进入盘点流程。
图7是本申请实施例提供的第二设备与第一设备的交互示意图，如图7所示，预先配置的active tag的RN范围为0至15，non-active tag的RN范围为大于15；若第二设备(reader/gNB)需要盘点RN范围为0至15的设备，在开始盘点时，reader/gNB分别发送query命令至active tag和non-active tag，active tag和non-active tag接收到Query命令后，active tag产生的RN为1，并将RN＝1反馈至reader/gNB；non-active tag产生的RN为21，并将RN＝21反馈至reader/gNB；reader/gNB根据active tag和non-active tag反馈的RN，向RN＝1的active tag发送ACK，并接收到active tag反馈的tag信息{PC/XPC，EPC}，active tag进入盘点流程；由于RN＝21的non-active tag不属于reader/gNB的盘点对象，则reader/gNB向RN＝21的non-active tag不反馈或者反馈无效指令，此时non-active tag无响应(No reply)，直至reader/gNB开始盘点non-active tag时，才对RN大于或等于16的non-active tag发送ACK，此时，non-active tag才会进入盘点流程。
2)显示指示。16bit RN中预留目标比特位(例如m-bit)用以区分第一设备的能力，例如，当区分active tag和non-active tag两种能力的设备时，需要1bit信息，因此可以将16bit RN分为两部分，使用最后1bit信息指示设备的能力；假设最后1bit信息 为0指示active tag，最后1bit信息为1指示non-active tag。第二设备当前需要盘点active tag时，根据最后1bit信息的指示反馈对应的ACK，active tag即可进入盘点流程。
可选地，所述方法还包括：
所述第一设备基于第三映射关系以及所述第一设备的能力，确定所述RN；所述第三映射关系包括设备能力与RN的映射关系；所述第一设备向所述第二设备发送所述RN。
具体地，第一设备接收第二设备发送的反馈RN的命令之后，第一设备基于第三映射关系以及第一设备的能力确定RN，若第一设备确定的RN与第二设备指示反馈的RN相同，则第一设备向第二设备发送第一设备确定的RN；其中，第三映射关系包括设备能力与RN的映射关系。
可选地，所述第三映射关系由网络配置或协议预定义。
可选地，在一种实施例中，第二设备可以通过是否为第一设备提供连续波(Continuous Wave，CW)，以分阶段对第一设备进行盘点。例如，在同一场景下同时部署了active tag、semi-passive tag和passive tag等三种能力的tag，其中semi-passive tag和passive tag属于non-active tag类型，reader在盘点的第一阶段并不发送CW，此时non-active tag无法响应reader的盘点，因此第一阶段只有active tag进入盘点流程；第二阶段reader在盘点之前先发送CW，non-active tag利用该CW实现反向散射通信，进入盘点流程。
