为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、反向散射通信。
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，可以是以下任一项设备：
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Tag，属于无源物联网(Internet of Things，IoT)设备(Passive-IoT),
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；
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阅读设备发送信息。该阅读设备可以为基站或者阅读器。
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。
二、盘点模式。
在盘点模式下，要求阅读设备发送查询指令(Query)后Tag响应回应(Reply)，即产生一个16-bit的随机数给阅读设备。然后阅读设备将该序列通过确认(Acknowledged，ACK)指令发给Tag后，Tag将相关的数据发送给阅读设备。
三、反向散射场景。
阅读设备发送连续波(continuous wave)和控制信令给tag，其中，控制(control)类型包括如下至少一项：选择(select)、盘点(inventory)和访问(access)。
四、信标(beacon)信号
Beacon信号的用途一：终端在进行低功耗唤醒信号检测过程中可能发生运动或者因为环境变化，移出低功耗唤醒信号的覆盖范围，导致无法收到网络侧设备发送的唤醒信号。因此，beacon(信标)信号的作用之一是用于测量，实现终端对网络侧设备信号质量的跟踪，避免由于终端移出唤醒信号的覆盖范围而造成失去服务的问题。
Beacon信号的用途二：为保持低功耗唤醒接收机与接入点(Access Point，AP)间同步，相关技术中采用周期性发送唤醒接收机信标(Wake-up Receiver beacon，WUR beacon)信号来传递时间信息，唤醒接收机信标媒体接入控制(Medium Access Control，MAC)帧(WUR beacon MAC frame)的类型相关控制(type dependent control)携带AP的时间同步功能(Synchronization function，TSF)时钟(timer)64比特中的[5:16]共12比特信息，用户收到该12比特信息后，根据时间更新准则，更新用户本地的TSF timer,从而达到与AP同步的目的。WUR beacon的发送周期和发送起始位置的偏移量由AP发送的操作单元(operation element)指示，周期为两次beacon发送间最少的TSF时间单元数，起始位置为相对于TSF0偏移的TSF时间单元数。当发生载波监听多路访问延迟(Carrier Sense Multiple Access deferrals，CSMA deferrals)，WUR beacon在当前周期会延迟发送，但在后续周期仍按WUR beacon的发送周期和发送起始位置确定的位置发送。
可选地，WUR beacon信号还用来做链路保持信号，当一段时间没有收到WUR beacon信号时，基站(Station，STA)必须进行WUR搜索或切换到主通信模块醒来的模式。当唤醒信号配置非连续接收(Discontinuous Reception，DRX)周期时，即按照DRX周期醒来监听唤醒信号时，唤醒信号也用来做链路保持信号，在未发送唤醒信号的DRX周期，AP可以发送WUR beacon用来做链路保持信号。其中，未接受到链路保持信号的时间通过用户实现来确定。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的反向散射通信处理方法进行详细地说明。
参照图2，本申请实施例提供了一种反向散射通信处理方法，如图2所示，该反向散 射通信处理方法包括：
步骤201，第一设备获取第一信息；
步骤202，所述第一设备根据所述第一信息和第一映射准则确定用于反向散射通信的目标上行上报流程；
其中，所述第一映射准则用于表示所述第一信息包括的信息内容与上行上报流程的映射关系，所述第一信息包括以下至少一项信息内容：时间窗信息、信道质量信息、传输波形信息、第一设备的需要传输的数据包大小、第一设备的上报频率、业务内容、覆盖信息、第一设备的状态和第一设备的位置信息；
其中，所述上行上报流程包括所述目标上行上报流程。
本申请实施例中，上述第一设备可以理解为标签设备，或者称之为标签，上述第一信息可以由第二设备发送，也可由第一设备检测得到，还可以是部分由第二设备发送，部分由第一设备检测得到。该第二设备为与所述第一设备进行反向散射通信的设备，具体的，该第二设备可以理解为阅读设备。可选地，在一些实施例中，该第二设备可以为基站、终端或接入和回传一体化(Integrated Access and Backhaul，IAB)节点。
可选地，上述第一映射准则由协议约定、网络侧设备配置或第二设备指示，所述第二设备为与所述第一设备进行反向散射通信的设备。
本申请实施例中，上述第一映射准则中每一信息内容可以对应至少两个上行上报流程。例如，针对时间窗信息，不同的时间窗的长度对应不同的上行上报流程。针对信道质量信息，不同的信道质量强度可以对应不同的上行上报流程。
需要说明的是，在本申请实施例中，第二设备可以持续或周期性发送连续波(Continuous Wave，CW)，在第一设备基于第一信息和第一映射准则确定目标上行上报流程后，可以主动上报相应的标签数据。例如，当第一设备检测到火灾时才会主动上报，否则不上报。在该应用场景下，第二设备无需对第一设备进行盘点，只需要根据第一设备上报的信息进一步做出反应即可，进一步，只要第一设备选择自主上报，即说明异常情况的发生，如，发生火灾。第二设备避免了多次盘点，第一设备避免了频繁响应。且第一设备的反馈均为有效信息，极大了提高了效率。上述标签数据可以理解为业务内容。
当然针对主动上报的场景应用还可以扩展到温度、运动、振动、空气质量、湿度或辐射等异常情况发生概率小，但是异常事件发生后会产生严重后果的场景。
本申请实施例通过第一设备获取第一信息；所述第一设备根据所述第一信息和第一映射准则确定用于反向散射通信的目标上行上报流程。这样，第一设备可以基于确定的目标上行上报流程进行主动上报，从而提高上报信息的时效性。因此，本申请实施例提高了标签数据的获取效率。
可选地，在一些实施例中，在所述第一信息包括至少两项所述信息内容，且至少两项所述信息内容分别具有对应的优先级的情况下，所述第一设备根据所述第一信息和第一映射准则确定用于反向散射通信的目标上行上报流程包括：
所述第一设备根据目标信息内容和所述第一映射准则确定所述目标上行上报流程，所述目标信息内容为所述至少两项信息内容中优先级最高的信息内容。
本申请实施例中，假设上述第一信息包括时间窗信息、信道质量信息和业务内容，且业务内容的优先级最高，此时可以基于业务内容确定目标上行上报流程。
可选地，在一些实施例中，所述信息内容的优先级由协议约定、网络侧设备配置或第二设备指示，所述第二设备为与所述第一设备进行反向散射通信的设备。
可选地，在一些实施例中，所述第一设备根据所述第一信息和第一映射准则确定用于反向散射通信的目标上行上报流程之后，所述方法还包括：
所述第一设备向第二设备发送第二信息，所述第二信息用于确定所述目标上行上报流程。
本申请实施例中，第一设备可以向第二设备发送第二信息，以告知进行标签信息的上报流程，从而使得第二设备能够准确获取第一设备上报的标签信息。可选地，通过上述第二信息可以隐性或显性的指示上述目标上行上报流程，具体的指示方式可以根据实际情况进行设置，在此不做进一步的限定。
可选地，在其他实施例中，第一设备也可以不向第二设备指示目标上行上报流程，第二设备可以基于盲检确定目标上行上报流程，这样可以减少信令的开销。
可选地，在一些实施例中，所述时间窗信息是由第二设备或网络侧设备为所述第一设备配置的上报时间资源，所述上报时间资源包括上报时间窗的持续时间和上报时间窗的起始位置中的至少一项。
可选地，在一些实施例中，在所述第一信息包括所述业务内容、且基于业务内容确定所述目标上行上报流程的情况下，所述第一设备根据所述第一信息和第一映射准则确定用于反向散射通信的目标上行上报流程包括：
所述第一设备确定所述业务内容的重要性排名；
所述第一设备基于所述重要性排名和所述第一映射准则确定所述目标上行上报流程。
本申请实施例中，可以预先定义各业务内容的重要性排名的关联关系，根据该关联关系确定当前待上报的业务内容的重要性排名，从而确定目标上行上报流程。该目标上行上报流程为当前待上报的业务内容的重要性排名对应的上行上报流程。
可选地，在一些实施例中，所述第一设备的状态与以下至少一项关联：第一设备是否为有源设备，第一设备的剩余电量，第一设备的温度，第一设备进行上报的紧急程度以及第一设备的存储器(memory)的存储情况。
本申请实施例中，可以基于是否为有源设备、剩余电量、温度、上报的紧急程度和存储器的存储情况中的至少一项进行状态划分，上述第一映射规则中可以包括不同的状态对应的上行上报流程。在基于第一设备的状态确定目标上行上报流程时，终端首先可以根据状态的划分规则确定当前的状态，然后基于第一映射规则确定目标上行上报流程。
可选地，在一些实施例中，所述传输波形信息包括以下至少一项：调制方式、调制阶 数和传输速率。
本申请实施例中，上述调制方式可以包括：二进制启闭键控(On-Off Keying，OOK)，幅移键控(Amplitude Shift Keying，ASK)和频移键控(Frequency-shift keying，FSK)中的至少一项。上述传输速率可以包括数据速率(data rate)和码片速率(chip rate)。
需要说明的是，上述信道质量信息可以由第一设备检测获得，也可以由第二设备检测并发送给第一设备。
可选地，在一些实施例中，所述第一设备获取第一信息包括：
所述第一设备检测第一参考信号；
所述第一设备基于所述第一参考信号的检测结果确定所述覆盖信息和所述信道质量信息中的至少一项。
本申请实施例中，上述第一参考信号可以为beacon信号，比如检测到beacon信号或正确检测的概率高，说明距离近，覆盖好，未检测beacon信号或正确检测概率过低，说明距离远，覆盖差。
可选地，在一些实施例中，所述位置信息用于表示以下至少一项：室内、室外、郊区和绝对的位置坐标。
可选地，在一些实施例中，所述第一设备获取第一信息包括：
所述第一设备从第二设备接收所述时间窗信息、所述信道质量信息和所述传输波形信息中的至少一项。
可选地，所述第一信息包括的信息内容关联的上行上报流程包括M步(step)上报流程，M为正整数。
例如，在一些实施例中，上述M可以为2或4，即所述第一信息包括的信息内容关联的上行上报流程可以包括2步上报流程和4步上报流程中的至少一项。
可选地，针对4步上报流程，具体流程如下：
Msg1：上行信号，主要用于标签上行汇报请求；
Msg2：下行信号，主要用于5G基站(gNodeB，gNB)/阅读器(reader)对标签上行汇报请求的响应；
Msg3：上行信号，主要用于标签数据上报；
Msg4：下行信号，主要用于gNB/reader对标签数据上报的确认。
采用4步上报流程可以具有以下优点：
1、提升传输效率，适合大数据包传输。Msg 3可以用高阶调制传输，不需要用Msg1的序列传输方式，比特效率提高；Msg3的长度不受限，可以一次传输大量比特。
2、降低数据传输失败概率。若Msg1采用序列传输，在信道质量较差时的接收端检测成功概率可以得到提升；同时，由于Msg1仅携带少量信息，数据包长度较短，多个Tag同时传输导致冲突的概率较低。
可选地，针对2步上报流程，具体流程如下：
MsgA：上行信号，主要用于标签数据上报；
MsgB：下行信号，主要用于gNB/reader对标签数据上报的确认。
采用4步上报流程可以具有以下优点：可以一次性传输完所要传输的数据，占用资源少，传输时延短，适用于数据包长度较短，信道质量较好的环境。
可选地，在一些实施例中，上述上报流程可以为基于竞争的上报或基于非竞争的上报。
在基于竞争的上报中，tag与其他tag共享的前同步码池中随机选择前导码，这意味着tag具有选择与另一个tag选择到相同前导码的风险，并且随后可能经历冲突或竞争的过程。
在基于非竞争的随机接入中，前同步码由reader或基站分配，这里的前同步码为随机接入前导码，每个tag有专用前导码，不会发生接入序列冲突。
可选地，在一些实施例中，所述信道质量信息包括以下至少一项：参考信号接收功率(Reference Signal Received Power，RSRP)，参考信号接收质量(Reference Signal Received Quality，RSRQ)和信噪比(Signal Noise Ratio，SNR)。
为了更好的理解本申请，以下通过一些实例进行详细说明。
可选地，在一些实施例中，上述第一映射准则包括时间窗信息与上报流程的第一映射方式，该第一映射方式包括以下至少一项：若配置了足够的时间资源，而且tag上报的可用时间也足够选择4-step，则选择4-step上报流程；若配置了足够的时间资源但是tag可用时间不足选择4-step，tag选择4-step并且在时间窗内发送上行请求(msg1)；若配置了不充裕的时间资源，选择2-step上报流程。
可选地，在一些实施例中，上述第一映射准则包括数据包大小与上报流程的第二映射方式，该第二映射方式包括以下至少一项：若数据包大小D大于S bit，tag选择4-step上报流程；若是数据包大小D小于或等于S bit，tag选择2-step上报流程。其中，S bit可以是预定义的，也可以是由网络侧设备或第二设备配置的。
可选地，在一些实施例中，每种业务内容预先定义了其重要性排名，上述第一映射准则包括业务内容与上报流程的第三映射方式，该第三映射方式包括以下至少一项：重要性较高，需要时延较短的业务，tag选择2-step上报流程；重要性较低的业务，tag选择4-step上报流程。
可选地，在一些实施例中，上述第一映射准则包括覆盖信息与上报流程的第四映射方式，该第四映射方式包括以下至少一项：检测到beacon信号或正确检测beacon的概率大于某个阈值，说明距离近，覆盖好，tag选择2-step上报流程；未检测beacon信号或正确检测beacon的概率小于等于某个阈值，tag选择4-step上报流程。其中，该阈值可以是预定义、由网络侧设备配置或第二设备配置。
可选地，在一些实施例中，上述第一映射准则包括传输波形信息与上报流程的第五映射方式，该第五映射方式包括：当调制方式振幅键控(M-Amplitude Shift Keying，M-ASK)或者频率键控(M-Frequency Shift Keying，M-FSK)高于某个阶数或者传输速率chip rate，data rate大于某一数值时，选择4-step上报流程，此时主要是为了保证传输的成功率。其 中，该阈值可以是预定义、由网络侧设备配置或第二设备配置。
可选地，在一些实施例中，上述第一映射准则包括信道质量信息与上报流程的第六映射方式，该第六映射方式包括以下至少一项：信道质量好的时候可以选择2-step上报流程；信道质量差的时候，选择4-step上报流程。
可选地，在一些实施例中，上述第一映射准则包括标签的状态与上报流程的第五映射方式。其中，标签的状态可根据多种情况来划分，比如紧急程度，memory存储情况或其他情况。根据紧急程度可分为紧急状态或者平时状态。根据memory存储状态可分为满载状态(存储量大于某一个值)或者空闲状态。可选地，该第五映射方式包括以下至少一项：
状态1：紧急状态，需要短时延，选择2-step上报流程；
状态2：平时状态，选择4-step上报流程。
可选地，在一些实施例中，考虑火警传感器(sensor)的应用场景，在该场景下网络先是发送第一配置时间包括时间窗持续时间T(根据预设准则：时间窗长度够大，可以选择4-step上报流程)和优先级表格。优先级表格如下：
Tag传输的第一信息包含包大小D(根据第一映射准则：D<s，选择2-step上报流程)，业务内容温度(根据第一映射准则：温度属于重要信息，选择2-step上报流程)，tag状态(紧急状态)(根据第一映射准则：紧急状态，选择2-step上报流程)。
如果tag没有获得第一信息的某项内容，就将该内容对应的优先级等级置0。
根据以上的优先级表格，最终tag选择2-step上报流程。
可选地，在一些实施例中，如图3所示，网络侧设备或第二设备配置了时间窗信息，包含上报时间窗的持续时间和时间窗的起始位置，而tag则需要在该时间窗内进行上报。
此时，网络侧设备或第二设备配置了足够的时间资源，因此tag选择了4-step的上报流程。对于tag1，发起上报的时间较早，可用时间多，因此能顺利在时间窗T内完成一次完整的上报。而对于tag2，发起上报的时间较晚，可用时间不多，不足以在时间窗T内完成一次完整的上报，因此tag2则在该时间窗发起上报请求(对应msg1的过程)，在下一个上报时间窗来临后，完成上报的剩余动作(对应msg3)。
参照图4，本申请实施例还提供了一种反向散射通信处理方法，如图4所示，该反向散射通信处理方法包括：
步骤401，第二设备向第一设备发送时间窗信息、信道质量信息、传输波形信息、优先级信息和第一映射准则中的至少一项；
