技术领域
本申请属于通信技术领域，具体涉及一种传输方法、装置、通信设备及反向散射设备。
背景技术
反向散射通信(Backscatter Communication，BSC)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：
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),
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读取器(Reader)发送信息。
常规的反向散射通信包括：网络发送载波和信令给Tag并接收Tag的反射信号；或者，网络发送载波和信令给Tag；终端接收Tag发送的反向散射信息。在常规的反向散射通信的中，网络发送前向信号(载波和控制命令)，Tag基于载波进行反向散射传输，两者传输信号所在频率较为接近，那么接收tag的反向信号时面临严重的自干扰。

由于不同场景中上FDD的频谱资源分配不同，本申请实施例中第一通信设备指示反向散射设备传输反向信号的频率位置，以适应上下行频谱的不同间隔、FDD的不同频谱资源分配等。
在本申请的至少一个实施例中，所述控制命令包括以下至少一项：

在本申请的又一个可选实施例中，所述方法还包括：

根据第一公式，确定第二频率位置；其中，第一公式为：Y＝mod(X，Z)；
其中，Z为频率位置集合中的包括的频率位置数量；X为临时随机数标识或标识号或编号；所述频率位置集合中第Y个频率位置为所述第二频率位置。
假设以第一通信设备为基站(gNB)，反向散射设备为标签(Tag)为例：
对于盘点类的业务，gNB通常是和特定的tag进行通信，而是和多个tag随机的进行通信。如果tag可以支持在多个频率的上进行反向传输，那么tag需要通过一定的规则确定反向传输的频率位置，具体的可以通过如下的方式确定：
通过tag生成的随机数或者tag表示或者tag编码确定，例如频率位置集合中频率位置的数量为Z，则tag反向散射的频率位置可以根据Y＝mod(X,Z)确定，即在第Y个频率位置，其中Y＝1,2,3，…Z-1；X为随机数或者tag标识号或tag编码。Z可以是预定义的或者通过控制命令指示的。
上述方式本质上属于对tag进行分组的方式，将tag分配到不同的频率资源上，使用这种方法可以使得多个tag的反向传输分布到不同频率资源上同时传输，提升盘点流程的效率。

其中，所述数据量或所述信道测量值与所述频率位置的对应关系由第一通信设备指示确定，或由预定义确定。
假设以第一通信设备为基站(gNB)，反向散射设备为标签(Tag)为例：
一种实现方式中，根据tag的数据量确定，例如，如果tag的数据量属于预设区间，则使用对应的频率传输；所述数据量和频率的对应性为预定义的，或者gNB指示的。数据量大和数据量小的tag可以同时在不同的频率上进行反向传输，数据量较大的tag通常也需要信道质量较好的频率资源传输，以保证传输的性能。一种实现方式可以是将数据量较大的tag分配到信道质量较好的频率资源上，而将数据量较小的tag分配到信道质量较差的频率资源上。以保证数据量较大的tag反向传输的性能。优选的，不同数据量的tag反向传输对应的频率资源可以是预定义的，或者gNB指示的。
另一种实现方式中，根据tag的对信道测量值确定，如RSRP，RSRQ等，如果tag的对下行接收的测量值属于预设区间，则使用对应的频率传输；所述测量值和频率的对应性为预定义的，或者gNB指示的。信道质量不同的tag可以同时进行反向散射传输，以提升传输效率。不同信道质量的tag，传输的性能不同，可以将信道质量较好的tag分配到信道质量相对较差的频率资源上进行反向传输；将信道质量较差的tag分配到信道质量相对较好的频率资源上进行反向传输。可以平衡不同信道质量的tag之间传输的性能。优选的，信道质量较好或者较差的频率位置可以由gNB指示。
作为又一个可选实施例，在所述第一信息为反向散射设备的类型的情况下，所述反向散射设备根据第一信息，确定与所述第一信息对应的第二频率位置，包括：
根据所述反向散射设备的类型，确定所述第二频率位置为与所述类型对应的频率位置；其中，所述类型与所述频率位置的对应关系由第一通信设备指示确定，或由预定义确定。例如，对于第一类型的反向散射设备，在某一频率位置进行反向传输；对于第二类型的反向散射设备，在另一频率位置进行反向传输。
假设以第一通信设备为基站(gNB)，反向散射设备为标签(Tag)为例：
可选地，不同类型的tag支持的传输参数不同，例如支持传输的频率位置不同，或者发送信号的功率不同，或者支持的调制方式不同。通过上述方式，gNB可以在对应的频率位置使用相应的参数进行反向信号的接收，当gNB覆盖范围内存在多种不同类型的tag时，将不同类型的tag的传输分散到不同的频率位置同时进行反向传输，gNB使用相应的参数进行接收，可以实现多个tag的并行传输，提升盘点流程的效率。

需要说明的是，本申请实施例提供的反向设备不限于只能基于反向散射的通信方式，也支持主动发送反向信号的通信方式；在此不做具体限定。换言之，反向散射设备进行的反向传输可以为反向散射传输，或者主动的反向传输。
可选地，在第一通信设备获取到反向散射设备支持的传输频率位置的能力信息后，根据所述能力信息为反向散射设备配置第二频率位置。
可选地，反向散射设备向所述第一通信设备发送所述反向散射设备支持的传输频率位置的能力信息，包括：
所述反向散射设备在传输临时随机数标识时上报所述能力信息；
或者，
所述反向散射设备在所述反向散射设备传输的反向信号中携带所述能力信息。
换言之，反向散射设备可以在盘点过程中进行能力信息上报，以支持和第一通信设备更灵活的通信，提升信号传输的性能；且由于能力信息的上报可以使得反向散射设备被分配到不同的频率位置进行并行传输，提升盘点类业务的传输效率。
综上，在本申请实施例中，第一通信设备在第一频率位置上发送前向信号，和/或，第一通信设备在第二频率位置上接收反向散射设备发送的反向信号；其中，所述第一频率位置和所述第二频率位置满足下述任意一项条件：所述第一频率位置属于频分双工FDD频段的下行频谱，所述第二频率位置属于FDD频段的上行频谱；所述第二频率位置所属的频段band与所述第一频率位置所属的band不同；所述第二频率位置对应的载波与所述第一频率位置对应的载波不同；所述第一频率位置和所述第二频率位置属于特定频段中的不同频率子带；本申请实施例中第一通信设备和反向散射设备传输信号的频率有相对较大的频率间隔，从而降低第一通信设备的收发自干扰。
为了更好的描述本申请实施例提供的传输方法，下面结合几个示例进行详细说明；其中，下述示例中以第一通信设备为基站(gNB)，反向散射设备为标签(Tag)为例进行说明。
示例1，如图4所示，在FDD的下行(DL)频谱上发载波，在上行(UL)频谱上反向散射信号
gNB发送载波和控制命令在FDD的下行频谱，tag在FDD的UL频谱上进行反向散射传输，gNB在UL频谱上接收反向散射传输的反向信号。这种传输方式下，反向信号的频率位置位于FDD频段的上行频谱，这样收发的自干扰可以做到很好的隔离。相关技术中的蜂窝网络中的FDD基站，也可以不同修改射频电路，就可以支持和这种标签设备的通信。
此外，进行上述载波和控制命令传输的下行频谱和上行频谱可以位于不同的band或者不同的载波(carrier)，在蜂窝网中，不同的carrier或者band通常使用独立的收发电路，这样基站可以使用多个频段的收发电路，同时进行下行发送，或者上行接收。这种情况下，原理和在FDD频谱上进行传输类似，可以使用两个独立的收发电路，实现全双工通信时隔离收发干扰。
示例2，gNB指示tag反向传输的频率位置
gNB需要指示tag反向传输的频率位置，包括传输的频率是高于还是低于gNB发送的载波或控制命令的频率，或者包括传输频率相对于gNB载波或者控制频率的偏移值。该偏移值属于多个频率值中的一个，可以基于GNB的指示在载波或者控制信号频率的更高额频率位置或者更低的频率位置。gNB可以通过bitmap指示具体的传输频率位置。例如，一共有8个频率位置可用于反向传输，高于和低于载波频率的频率位置各4个。gNB可以通过3bit长的bitmap指示出具体的频率位置，包括1bit指示反向传输是高于还是低于载波频率位置，两bits用于指示其中一侧的4个频率位置中的1个。
gNB发送控制命令指示频率位置信息，所述控制命令包括：
第一控制命令，例如用于确定的满足特定的一个或者多个条件的Tag进行发送或者接收的控制命令。例如，gNB可以发送第一控制命令，选择满足条件的tag，例如特定厂商生产的tag，特定内存数值的tag等，进行通信；gNB可以在该控制命令中同时指示反向传输的频率。
第二控制命令，例如用于指示反向传输参数(包含传输速率，调制方式，或者编码方式)的控制命令。gNB在指示tag进行传输时，会同时指示传输的参数，包括传输速率，传输的编码方式(例如，FM0，Miller)等控制信息。gNB可以在该控制命令中，同时指示反向传输的频率。
第三控制命令，例如用于指示tag改变判断过程中存储的计数数值的控制命令。对于盘点类的业务，在gNB完成和一个tag的通信之后，会通过QueryRep命令，改变tag的随机产生的计数值，满足特定条件的计数器数值的tag后续和gNB进行通信，其他tag不进行通信。gNB可以在该控制命令中，同时指示反向传输的频率。
第四控制命令，例如用于指示改变盘点参数，包括改变用于确定tag随机数范围的参数的控制命令。对于盘点类的业务，在gNB可以指示一个数值Q，tag生成的随机计数值根据Q确定，例如，tag产生的随机计数值属于{0,1，…,2^Q-1}。gNB可以在该控制命令中，同时指示反向传输的频率。
第五控制命令，例如用于指示ACK信息的控制命令。当gNB接收到tag传输的信息后，需要想tag指示Ack信息，指示该信息已经正确接收。gNB可以在该控制命令中，同时指示反向传输的频率。
Tag在接收到该控制命令后，在后续的反向传输中，根据指示的反向传输的频率进行传输。
优选的，在gNB和tag进行数据传输之前，tag可以向gNB指示支持的传输频率位置的能力，包括以下
a)Tag传输频率高于gNB频率的，或者低于gNB的频率；
b)支持频率偏移的集合，
c)支持频率偏移的数目
d)主动发送信号的绝对频率位置的集合
Tag在传输临时随机数标识，或者tag的编码的信号或者信道中，同时上报所述的频率偏移能力。gNB接收到该信号中，可以在后续的传输中，指示tag在对应的频率上进行反向传输，增加gNB调度传输的灵活性，可以提升反向传输性能。
综上，本申请实施例提供的传输方法中，gNB在下行频谱上发载波或者控制命令，tag在上行频谱上进行反向传输，以避免gNB作为Reader的自干扰问题。此外，当tag传输的频率资源可以是相对于载波的不同偏移的频率资源时，可以进一步分配tag传输的频率资源，可以根据tag的类型，tag的数据量，tag的ID，信道质量等确定tag进行反向传输的频率资源。
