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的信息传输方法、装置、终端及网络侧设备进行详细地说明。
反向散射(Backscatter)是指反向散射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信息。反向散射通信设备，可以是：
无源标签(Tag)，属于无源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Tag可以不依赖对入射信号的反射向阅读器(reader)发送信息。
本实施例中，反向散射设备以Tag为举例进行介绍。
传统的射频识别技术(Radio Frequency Identification，RFID)的设计在盘点模式下，要求读取器发送查询指令(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。
在现有的反向散射通信系统中，reader在同一个时刻通常只能接收一个Tag的反向散射信号。例如在RFID的盘点流程中，reader发送控制命令开启盘点流程时，会指示一个数值Q。Tag在本地产生一个{0，…，2Q-1}的数值中，随机选一个数值q。当前随机数值为0的Tag会响应reader的控制命令，进行反向散射信号的传输。当前的随机数值不为0的Tag暂不进行反向散射信号的传输。Reader在完成和随机数值为0的Tag的通信之后，可以继续发送控制命令(例如，重复查询queryRep)，例如，指示Tag对生成的随机数减1，随机数值减为0的Tag响应该控制命令，进行反向散射传输。
需要说明的是，本申请实施例提供的终端参与的反向散射通信的应用场景如图2-图4所示，但本申请实施例所适用的场景不限于此。其中，图2中网络侧设备发送激励载波和控制命令给反向散射设备(如标签Tag)，终端接收Tag反射的反向散射信息。图3中终端发送激励载波和控制命令给Tag；网络接收Tag反射的反向散射信息；其中，命令类型包括如下至少一项：选择(select)，盘点(inventory)，访问(access)。图4中终端既发送激励载波和控制命令给Tag，又接收tag的反向散射信号。而网络侧设备可以进行一些反向散射通信的配置等，在此不做限定。
如图5所示，本申请实施例提供一种反向散射通信的信息传输方法，包括：
步骤201，终端向网络侧设备发送第一信息，其中，所述第一信息用于辅助反向散射通信的相关配置更新和/或传输调整，所述第一信息包括以下至少一项：
盘点相关信息；
反向散射设备的反向散射相关信息；
激励载波和/或控制命令的相关信息。
在本申请的至少一个可选实施例中，反向散射通信可以理解为反向散射信道或信号的 传输，其中反向散射信道或信号传输包括：(1)激励载波，(2)控制命令，以及(3)反向散射信息。具体的：
(1)激励载波；一种实施例中，该激励载波可以是由网络侧设备发送给标签(tag)的，还可以是由终端发送给标签的。
(2)控制命令(command)，例如：选取命令、查询命令、重复查询命令、答复命令、读取命令、写入命令、随机请求命令等；一种实施例中，该控制命令可以是由网络侧设备发送给标签(tag)的，还可以是由终端发送给标签的。
可选地，所述控制命令可以包括以下至少一项：选择类型命令，查询类型命令，接入命令；其中，所述选择类型命令包括以下至少一项：选择命令(一个具体的选择命令)，盘点命令，排序命令；所述查询类型命令包括以下至少一项：查询命令(一个具体的查询命令)，调节查询命令，重复查询命令；所述接入命令包括以下至少一项：随机请求命令，读取命令，写入命令，销毁命令，锁定命令，访问命令，安全相关接入命令，文件管理相关接入命令。
选择类型(Select)命令是必备的，由于标签有多种属性，基于用户设定的标准和策略，使用选择类型命令，改变某些属性和标志就人为选择或圈定了一个特定的标签群，可以只对它们进行盘点识别或存取操作，这样有利于减少冲突和重复识别，加快识别速度。
盘点阶段的命令用于开始一次盘点。例如，查询命令用于启动一轮盘点，并决定哪些标记参与该轮盘点；调节查询命令用于将标签原来接收时刻(Slot)的数目进行调整；重复查询命令用于减少标签Slot的数字。
接入命令(Access)中，随机请求(Req_RN)命令要求标签产生一个随机数；读取命令用于从标签的存储中的某个位置读取资料；写入命令用于写入资料到标签的存储中；销毁命令可以隐私的泄漏，标签无法再使用；锁定命令用于标签不能再进行写入的动作，防止资料被任意的串改；访问命令用于当标签拥有密码时候让标签从开启(Open)的状态转成保护(Secure)状态；安全相关接入命令用于保障标签安全；文件管理相关接入命令可以用于对标签内文件进行管理。
(3)反向散射信息，例如：Tag标识信息(如查询过程中的临时代表Tag身份的16-bit随机数)、电子产品代码信息、Tag状态信息等)。一种实施例中，该反向散射信道或信号可以是标签通过反向散射发送给终端的，还可以是标签通过反向散射发送给网络侧设备的。
作为一个可选实施例，在步骤201中终端向网络侧设备发送第一信息之前，该方法还包括：
终端监听用于反向散射通信的信道或信号；
相应的，步骤201包括：
终端根据所述用于反向散射通信的信道或信号的监听结果，向网络侧设备发送第一信息。
可选地，用于反向散射通信的信道或信号包括：(1)激励载波(2)控制命令，以及 (3)反向散射信息。具体解释参见上述1)激励载波(2)控制命令，以及(3)反向散射信息对应描述，在此不赘述。
在本申请的至少一个实施例中，所述盘点相关信息包括以下至少一项：
Q的推荐取值，所述Q为用于管理反向散射设备响应概率的参数；
建议增大所述Q的取值；
建议减小所述Q的取值；
一次控制命令支持控制的反向散射设备预期个数；
N的推荐取值；其中，终端每间隔N轮盘点后将所述终端接收到的反向散射设备的反向散射信息上报给所述网络侧设备；
推荐的盘点方式。
例如，一种情况下，如果Q值的选取过小，则会导致多个反向散射设备(如tag)本地产生相同的随机数的概率增加，而导致在某个时刻多个tag同时进行反向散射传输的可能，这种情况下，reader大概率无法检测出任何tag的反向散射信号。此种情况下，终端可以通过第一信息建议增大所述Q的取值，或者直接在第一信息中携带Q的推荐取值，该推荐取值大于Q的当前取值。以由网络侧设备在盘点过程中逐渐则增大Q值，以选取到合理的Q值。
而另一种情况下，如果Q值的选取过大，则会导致tag选取到0值，或者选取到较小的值的概率降低，导致很多次query都没有质询到任何Tag的情况出现。此种情况下，终端可以通过第一信息建议减小所述Q的取值，或者直接在第一信息中携带Q的推荐取值，该推荐取值小于Q的当前取值。以由网络侧设备在盘点过程中逐渐则减小Q值，以选取到合理的Q值。
需要说明的是，一次控制命令支持控制反向散射设备指的是：一次控制命令支持触发反向散射的反向散射设备或一次控制命令指示反向散射的反向散射设备。
可选地，“一次控制命令所期望作用的反向散射设备个数”包括：一次盘点回合中盘点反向散射设备的个数。其中，一次盘点回合指的是以发起一个query(查询)命令为起始并以发起后续的query命令或选择命令(select command or challenge command)为结束的这段时间。
本申请实施例中质询器或读写器(reader)和标签(Tag)之间的信息传输包括：
a.选择(Select)操作：质询器选择标签群进行后续清点或以密码方式挑战标签群以进行后续身份验证的过程。选择包括选择和挑战命令。
b.盘点(Inventory)操作：质询器识别标签的过程。质询器通过在四个会话之一中传输查询命令来开始盘点。一个或多个标签可能会回复。质询器检测到单个标签回复并从标签请求协议控制位(protocol control，PC)、可选的扩展协议控制(Extended Protocol Control，XPC)字、电子产品码(Electronic Product Code，EPC)和循环冗余校验(Cyclic Redundancy Check，CRC)-16。一轮盘点一次只在一个会话中运行。盘点包含多个命令， 其中非常重要的命令为查询相关的命令，例如查询命令、重复查询命令等。
c.访问(Access)操作：询问器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。询问器在访问前单独识别并唯一识别标签。访问包括多个命令。
具体的，质询器(reader)和标签(Tag)之前的命令(command)如表1所示。
表1



标签(Tag)的各个状态如表2所示。
表2
盘点操作中的Q可以理解为：质询器用来调节标签响应概率的参数。质询器指示盘点轮次中的标签将Q比特随机(或伪随机)数加载到其插时隙计数器中；质询器也可以命令标签减少它们的时隙计数器。当它们的时隙计数器(即它们的时隙)中的值为零时，标签会回复。Q是(0,15)范围内的整数；相应的标签响应概率范围从1到0.000031。简单来说，通过Q值来控制住一次盘点中的Tag population(标签数量)。
其中，时隙(Slot)对应于标签可能响应的盘点轮次中的点。Slot是Tag的时隙计数器输出的值；标签在其时隙(即时隙计数器中的值)为零时回复。具体的，Slot指的是Tag根据Q值，在0到2Q-1)中随机选择的一个数值。只有选择到了特定的slot取值，例如slot＝0的Tag才能进一步接收下一步的command。

综上，在本申请实施例中，终端作为反向散射通信的Tag反馈接收端，终端将用于辅助反向散射通信的第一信息发送给网络侧设备，供网络侧设备进行反向散射通信的相关配置更新和/或传输调整，从而更快的进行盘点流程的调整，提高盘点效率。
为了更清楚的描述本申请实施例提供的信息传输方法，下面结合几个示例进行说明。
示例一，场景1和场景2中UE上报盘点相关信息
如图7所示，场景1为UE可以参与发送command(控制命令)和/或激励载波(Carrier Wave，CW)；如图8所示，场景2为UE仅进行接收反馈，不参与发送。
如图7及图8所示，在终端参与的反向散射通信中，网络侧设备(如，基站gNB)作为reader在发送query开启盘点流程时，会指示Tag一个Q值。这个Q值为reader/interrogator用来控制标签响应概率的参数。Tag根据Q值，在本地随机产生一个{0，…，2Q-1}范围内的数值，并将其写入到自己的slot counter(时隙计数器)中。Q值是一个范围在例如{0,15}中的整数。因此，对应的Tag回复概率范围为20＝1到2-15＝0.000031。而slot是盘点回合中Tag回应的点数。目前只有当前slot为特定值(例如slot＝0)的tag才会响应reader 的控制命令，进行通过反向散射来反馈信息。而slot值不为0的tag则暂不进行反向散射来也就是不反馈信息。
上述流程属于随机多址接入的流程，一种情况下，如果Q值的选取过小，则会导致多个tag本地产生相同的随机数的概率增加，而导致在某个时刻多个tag同时进行反向散射传输的可能，这种情况下，reader大概率无法检测出任何tag的反向散射信号。而另一种情况下，如果Q值的选取过大，则会导致tag选取到0值，或者选取到较小的值的概率降低，导致很多次query都没有质询到任何Tag的情况出现。因此，gNB需要在盘点过程中逐渐调整Q值，以选取到合理的Q值。
由于是三方通信，UE作为Tag反馈信息的接收方，可以根据Tag反馈的情况及时的上报一些辅助信息来帮助gNB快速调整一些参数取值，包括Q值。此外，结合不同的盘点流程，终端可以在辅助信息里放置一些其他有用的信息来帮助基站做判断，或者直接指示基站应该如何配置或选取盘点方式等。
而终端这种信息的上报触发方式可以是根据网络侧周期配置的上报资源来进行周期性的上报。也可以是网络侧通过配置给UE第一定时器并规定：在第一定时器运行时间内不能上报，而在第一定时器到期后上报辅助信息并重启定时器。由此终端可在定时器到期后，进行辅助信息的上报。此外，另一种方式中，也可以通过事件触发的方式来非周期性的上报该辅助信息。上述提及的三种上报方式可以同时被配置，由终端自主选择上报方式，或者网络指定上报方式。
示例二，场景1和场景3中UE上报Tag反向散射的相关信息
如图7所示，场景1为UE可以参与发送command(控制命令)和/或CW(激励载波)；如图9所示，场景3为网络授权终端与Tag进行两者的BSC通信。
如图7及图9所示，在终端参与的反向散射通信中，终端作为Tag通过backscatter反馈的接收端，可以通过对Tag反馈的接收情况，上报给网络侧设备一些UE侧的统计信息，例如，上报UE侧在一段时间内的接收到的Tag反馈信息接收错误次数和/或错误的原因等。
此外，除了上报上述Tag反馈的接收情况的统计信息外，UE可以结合接收到的tag反射信号的强弱，或者探测载波CW发送频率的无线环境，如时频域干扰情况等，上报/触发/通知网络对Tag发送参数进行调整，例如，改变Tag反馈的调制方式，编码方式等，以此来提升反向散射链路的传输性能。
示例三，场景1和场景2中UE上报激励载波和/或控制命令(command)的相关信息
如图7所示，场景1为UE可以参与发送command(命令)和/或CW(载波)；如图8所示，场景2为UE仅进行接收反馈，不参与发送。可选地，场景2中，UE可以通过接收网络发送的command和/或CW来进行信道测量。
例如，UE可以根据载波或者控制命令的接收或测量，评估下行发送的命令的传输可靠性，并反馈网络调整编码格式。如果信道质量较好，而且之前的tag反馈都能正确的接收，则说明信道质量很好，可以由此建议网络采用短格式的command进行发送以此提升 效率，反之，推荐网络配置长格式的command。当然，还可以通过上报其他参数的调整，比如编码方式，调制方式，时频域资源等等，在此不做限定。
