为了便于理解本申请实施例的传输控制方法，首先对如下相关技术进行介绍：
一、反向散射通信设备
反向散射通信设备，可以是如下中的其中一种：
第一种：传统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)；
第二种：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；
第三种：具备主动发送能力的Tag，即有源Tag(active Tag)，这类终端可以不依赖对入射信号的反射，主动生成载波信号并向5G基站(the next Generation Node B，gNB)或Reader发送信息。
其中，反向散射通信设备可以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表示天线特性阻抗，Z1表示负载阻抗。
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。

其中，图5中的RN16表示一个长度为16bit的随机数；PC表示协议控制(protocol  control)；PacketCRC表示包循环冗余校验。
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传输控制方法进行详细地说明。
第一方面，参见图6所示，为本申请实施例所提供的一种传输控制方法的流程图，该方法可以包括以下步骤601至602：
步骤601：第一通信设备估计第二通信设备的目标偏移。
这里，第一通信设备可以为Reader，其中，Reader可以为网络侧设备，也可为终端。第二通信设备可以为Tag。
其中，所述目标偏移用于指示所述第二通信设备传输信号的时域偏移和/或频域偏移。由此可知，第一通信设备可以估计第二通信设备传输信号的时域偏移和/或频域偏移，例如第一通信设备为Reader，第二通信设备为Tag，则Reader可以估计Tag传输信号时的时域偏移和/或频域偏移。
另外，上述时域偏移即为第二通信设备传输信号时采用的时域资源，相对于已经配置的时域资源的偏移；上述频域偏移即为第二通信设备传输信号时采用的频域资源，相对于已经配置的频域资源的偏移。
可选地，所述目标偏移包括如下A-1至A-2项中至少一项：
A-1项：频率偏移值；
A-2项：目标对象的持续时间偏移值，所述目标对象包括传输单位符号、码片、高电平、低电平中的至少一项。
上述A-1项，即为第二通信设备传输信号时采用的频率，相对于已经配置的频率的偏移值；
上述A-2项，表示第一通信设备可以估计第二通信设备传输信号时传输单位符号的持续时间偏移值、码片的持续时间偏移值、高电平的持续时间偏移值、低电平的持续时间偏移值、高电平和低电平的持续时间偏移值中的至少一项。
这里，传输单位符号的持续时间偏移值，即为第二通信设备用于传输信号的传输单位符号的持续时间，相对于已经配置的用于传输信号的传输单位符号的持续时间的偏移值；
码片的持续时间偏移值，即为第二通信设备用于传输信号的码片的持续时间，相对于已经配置的用于传输信号的码片的持续时间的偏移值；
高电平的持续时间偏移值，即为第二通信设备的传输信号的高电平的持续时间，相对于已经配置的传输信号的高电平的持续时间的偏移值；
低电平的持续时间偏移值，即为第二通信设备的传输信号的低电平的持续时间，相对于已经配置的传输信号的低电平的持续时间的偏移值；
高电平和低电平的持续时间偏移值，即为第二通信设备的传输信号的高电平和低电平的持续时间，相对于已经配置的传输信号的高电平和低电平的持续时间的偏移值。
步骤602：所述第一通信设备向所述第二通信设备发送所述目标偏移的参数信息。
其中，第二通信设备接收到第一通信设备发送的目标偏移的参数信息后，则可以根据该参数信息，调整第二通信设备传输信号的时域资源和/或频域资源，从而采用调整后的时域资源和/或调整后的频域资源，传输信号。
由上述步骤601至602可知，在本申请实施例中，第一通信设备能够估计第二通信设备的目标偏移，该目标偏移用于指示第二通信设备传输信号的时域偏移和/或频域偏移，从而使得第一通信设备向第二通信设备发送该目标偏移的参数信息。由此可见，在本申请实施例中，第一通信设备可以估计第二通信设备传输信号的时域偏移和/或频域偏移，从而向第二通信设备指示该偏移的参数信息，这样，第二通信设备则可以基于该偏移进行时域资源和/或频域资源调整，从而可以降低第二通信设备传输信号的时域资源和/或频域资源与其他信号的时域资源和/或频域资源相互干扰的几率，进而可以提升通信质量。
可选地，上述步骤601“所述第一通信设备估计第二通信设备传输信号的目标偏移”，包括：
所述第一通信设备分别对同步序列与第一集合中的每一个候选序列进行相关性计算，得到对应的相关序列，其中，所述同步序列为所述第一通信设备接收到的所述第二通信设备传输的信号的同步序列，不同的所述候选序列对应不同的所述目标偏移；
所述第一通信设备选择各个所述相关序列的最大值组成目标序列；
所述第一通信设备从所述目标序列中选出至少一个值作为目标相关值；
所述第一通信设备将所述目标相关值对应的候选序列对应的目标偏移，确定为所述第二通信设备传输信号的目标偏移。
这里，目标相关值对应的候选序列，即为目标相关值所属的相关序列对应的候选序列。
由此可知，在第一通信设备一侧存储有第一集合，该第一集合中包括多个候选序列，且每一个候选序列对应有相应的目标偏移(即时域偏移和/或频域偏移)。这里，目标偏移与第二通信设备的传输信号的波形存在对应关系，按照目标偏移后的传输信号波形对应的采样频率对该波形进行采样，则可以得到离散序列，该离散序列即为该目标偏移对应的候选序列。
例如第一集合中包括L个候选序列，则可以分别计算上述同步序列与每一个候选序列的相关序列，从而得到L个相关序列，然后分别选取每个相关序列中的最大值，得到一个有L个值的目标序列，进而可以从该目标序列中选择至少一个值作为上述目标相关值，则该目标相关值对应的候选序列对应的目标偏移即为第一通信设备估计的第二通信设备传输信号的目标偏移。
示例性地，第一集合中的候选序列为{A1 A2 A3 A4 A5},其中，A3序列是没有发生频域偏移和时域偏移的序列，此时该序列对应的每符号采样率为48，则第一集合中的各 个候选序列对应的采样率分别为：{48-2x,48-x,48 48+x,48+2x}(即每一个候选序列都有一个对应的采样频率)；
若目标波形是第二通信设备发送的信号的波形，则基于目标波形得到的同步序列，与前述A1至A5序列中的每一个候选序列进行相关计算，可以得到5个相关序列，从而可以分别从5个相关序列中选出最大值，这5个最大值组成一个目标序列，进而可以从目标序列中选出至少一个值作为上述目标相关值，例如选出的目标相关值属于A3序列对应的相关序列，则A3序列对应的目标偏移即为第一通信设备估计的第二通信设备发送的上述目标波形的目标偏移(即第一通信设备估计出第二通信设备发送的上述目标波形并未发生频域偏移和时域偏移)。
由此可知，在本申请实施例中，第一通信设备可以采用相关值比较的方法，估计出第二通信设备的目标偏移。
可选地，所述第一通信设备从所述目标序列中选出至少一个值作为目标相关值，包括：
所述第一通信设备选择目标排序中排位前M的值作为所述目标相关值，所述目标排序是所述目标序列中的值从大到小的排序，M大于零且小于或等于所述目标序列中的值的总数。
即第一通信设备可以选择上述目标排序中排位前M的值作为上述目标相关值(例如可以选择上述目标序列中的最大值作为上述目标相关值，或者选择上述目标序列中的最大值、第二最大值、第三最大值作为上述目标相关值)。这里，M的具体数值可以在网络侧设置。
可选地，所述参数信息包括如下B-1至B-4项中至少一项：
B-1项：频率偏移值；
B-2项：第二集合以及第一索引，所述第二集合包括至少一个频率偏移值，所述第一索引包括所述第二集合中的至少一个频率偏移值的索引；

上述B-1项表示：若第一通信设备估计的第二通信设备的目标偏移包括频率偏移值，则第一通信设备可以将该频率偏移值指示给第二通信设备。
上述B-2项表示：在第一通信设备侧可以维护第二集合，该第二集合包括至少一个频率偏移值，则若第一通信设备估计的第二通信设备的目标偏移包括频率偏移值，那么，第一通信设备可以将第二集合，以及第一通信设备估计的频率偏移值在第二集合中的索引指示给第二通信设备。
上述B-3项表示：若第一通信设备估计的第二通信设备的目标偏移包括目标对象的持续时间偏移值，则第一通信设备可以将该目标对象的持续时间偏移值指示给第二通信设备。
上述B-4项表示：在第一通信设备侧可以维护第三集合，该第三集合包括至少一个目标对象的持续时间偏移值，则若第一通信设备估计的第二通信设备的目标偏移包括目标对象的持续时间偏移值，那么，第一通信设备可以将第三集合，以及第一通信设备估计的目标对象的持续时间偏移值在第三集合中的索引指示给第二通信设备。
可以理解的是，第一通信设备估计的频率偏移值可以为一个或多个，若第一通信设备估计的频率偏移值为多个，则上述B-2项中的第一索引则包括第二集合中的多个索引；同理，第一通信设备估计的目标对象的持续时间偏移值也可以为一个或多个，若第一通信设备估计的目标对象的持续时间偏移值为多个，则上述B-4项中的第二索引则包括第三集合中的多个索引。
可选地，所述第二集合为：[-N*offset，….，-2*offset，-offset，0，offset，2*offset，…，N*offset]，其中，offset表示频率偏移值的步长，N表示频率偏移值的范围值；
和/或，

由此可知，上述第二集合中的频率偏移值可以按照从小到大的顺序排序，且每相邻的两个频率偏移值的间隔为第一预设值(即为上述的offset)；和/或，上述第三集合中的目标对象的持续时间偏移值可以按照从小到大的顺序排序，且每相邻的两个目标对象的持续时间的间隔为第二预设值(即为上述的T_offset)。
可选地，所述方法还包括：
所述第一通信设备接收所述第二通信设备发送的硬件能力信息和所述第二通信设备的频率偏移范围；
其中，offset、T_offset、N、K中的至少一项根据所述硬件能力信息和所述第二通信设备的频率偏移范围确定。
即上述第二集合中每相邻的两个频率偏移值的间隔，和/或上述第三集合中每相邻的两个目标对象的持续时间的间隔，根据上述硬件能力信息和第二通信设备的频率偏移范围确定；
上述第二集合中的频率偏移值的最大值，和/或上述第三集合中的目标对象的持续时间偏移值的最大值，根据上述硬件能力信息和第二通信设备的频率偏移范围确定；
上述第二集合中的频率偏移值的最小值，和/或上述第三集合中的目标对象的持续时间偏移值的最小值，根据上述硬件能力信息和所述第二通信设备的频率偏移范围确定。
可选地，所述参数信息承载在如下C-1项至C-4项中至少一项中：
C-1项：盘点的控制命令；
C-2项：查询的控制命令；
C-3项：读取的控制命令；
C-4项：发送查询所述第二通信设备的身份标识的控制命令。
其中，上述C-4项中的身份标识可以为临时身份标识。
由此可知，第一通信设备可以将上述目标偏移的参数信息携带在上述C-1至C-4项中的至少一项中发送给第二通信设备。

这里，第一通信设备可以为Reader，其中，Reader可以为网络侧设备，也可为终端。第二通信设备可以为Tag。
其中，所述目标偏移用于指示所述第二通信设备传输信号的时域偏移和/或频域偏移。由此可知，第一通信设备可以估计第二通信设备传输信号的时域偏移和/或频域偏移，例如第一通信设备为Reader，第二通信设备为Tag，则Reader可以估计Tag传输信号时的时域偏移和/或频域偏移。
另外，上述时域偏移即为第二通信设备传输信号时采用的时域资源，相对于已经配置的时域资源的偏移；上述频域偏移即为第二通信设备传输信号时采用的频域资源，相对于已经配置的频域资源的偏移。
可选地，所述目标偏移包括如下A-1至A-2项中至少一项：
A-1项：频率偏移值；
A-2项：目标对象的持续时间偏移值，所述目标对象包括传输单位符号、码片、高电平、低电平中的至少一项。
上述A-1项，即为第二通信设备传输信号时采用的频率，相对于已经配置的频率的偏移值；

这里，传输单位符号的持续时间偏移值，即为第二通信设备用于传输信号的传输单位符号的持续时间，相对于已经配置的用于传输信号的传输单位符号的持续时间的偏移值；

由上述步骤701至702可知，在本申请实施例中，第一通信设备能够估计第二通信设备的目标偏移，该目标偏移用于指示第二通信设备传输信号的时域偏移和/或频域偏移，从而使得第一通信设备向第二通信设备发送该目标偏移的参数信息。由此可见，在本申请实施例中，第一通信设备可以估计第二通信设备传输信号的时域偏移和/或频域偏移，从而向第二通信设备指示该偏移的参数信息，这样，第二通信设备则可以基于该偏移进行时域资源和/或频域资源调整，从而可以降低第二通信设备传输信号的时域资源和/或频域资源与其他信号的时域资源和/或频域资源相互干扰的几率，进而可以提升通信质量。

可以理解的是，第一通信设备估计的频率偏移值可以为一个或多个，若第一通信设备估计的频率偏移值为多个，则上述B-2项中的第一索引则包括第二集合中的多个索引；同理，第一通信设备估计的目标对象的持续时间偏移值也可以为一个或多个，若第一通信设备估计的目标对象的持续时间偏移值为多个，则上述B-4项中的第二索引则包括第三集合中的多个索引。
可选地，所述第二集合为：[-N*offset，….，-2*offset，-offset，0，offset，2*offset，…，N*offset]，其中，offset表示频率偏移值的步长，N表示频率偏移值的范围值；
和/或，

由此可知，在第二通信设备接收到第一通信设备发送的目标偏移的参数信息的情况下，则可以采用根据该参数信息调整后的时域资源和/或调整后的频域资源，在第一时间内传输信号；在第二通信设备未接收到上述参数信息的情况下，则可以采用预先确定的时域资源和频域资源(即默认的时域资源和频域资源)在第二时间内传输信号。
可选地，第一时间的优先级高于第二优先级，即在接收到上述参数信息的情况下，采用根据该参数信息调整后的时域资源和/或调整后的频域资源传输信号的优先级，高于采用预先确定的时域资源和频域资源传输信号的优先级。
综上所述，本申请实施例的传输控制方法的具体实施方式可如下所述：
在Reader侧，会维护第二集合：[-N*offset,….,-2*offset,-offset,0,offset,2*offset,…,N*offset]和/或第三集合：[-K*T_offset,…,-2*T_offset,-T_offset,0,T_offset,2*T_offset,…,K*T_offset]。
其中，offset表示频率偏移值的步长，T_offset表示目标对象的持续时间偏移值的步长，N表示频率偏移值的范围值，K表示目标对象的持续时间偏移值的范围值，目标对象包括传输单位符号、码片、高电平、低电平中的至少一项；参数N、offset、T_offset、K可以根据Tag上报的硬件能力以及Tag的频率偏移范围，设置为不同的值。
另外，每一个频率偏移值，都对应一个估计Tag的载波频率或者目标对象的持续时间长度。例如图8所示，当频率偏移值为0时，此时波形没有发生频偏，一个目标对象的持续时间是B，对应图中从上往下的第二个波形；当频率偏移值为N*offset时，此时频率发生了正向频偏，频率提高，导致时域的目标对象的持续时间变短，目标对象的持续时间是A，对应图中从上往下的第一个波形；当频率偏移值为-N*offset时，此时频率发生了负向频偏，频率降低，导致时域的目标对象的持续时间变长，目标对象的持续时间是C。由此可见，无论是发生了正向频偏还是负向频偏，都会改变目标对象的持续时间长度。
此外，对图8中的每一个波形按照相对应的采样频率进行采样，则可以得到离散序列，则每一个离散序列可以作为一个候选序列存储至第一集合中，这样第一集合中的每一个候选序列对应一个频率偏移值以及一个目标对象的持续时间的偏移值。即第一集合与前述第二集合以及第三集合中的元素存在对应关系。
而当发生频率偏移时，无论是发生了正向频偏还是负向频偏，都会改变目标对象的 持续时间长度，并且对应的候选序列也会发生改变，这样，Reader接收到的Tag发送的反射信号的同步序列与候选序列之间的相关值则会发生改变。
假设Tag发生了2*offset的频率偏移，则在Reader侧的第二集合中，只有2*offset这个频率对应的波形能够与Tag发生了频偏的波形相匹配，即这两个波形做相关才有最大相关值(亦即第二集合中2*offset这个频率对应的波形采样得到的候选序列，与Tag发生了频偏的波形(即Tag发送的反射信号)的同步序列，做相关得到的相关序列中才有最大相关值)，其它频率偏移值对应的波形与Reader收到的Tag发送的波形做相关的相关序列中的值均小于上述最大相关值，如图9所示。
当Reader侧估计出Tag的频率偏移值和/或目标对象的持续时间偏移值之后，Reader可以向Tag反馈如下a)至d)中的至少一项：
a)频率偏移值；
b)第二集合[-N*offset,….,-2*offset,-offset,0,offset,2*offset,…,N*offset]和至少一个频率偏移值索引F_index；
c)目标对象的持续时间偏移值；
d)第三集合[-N*T_offset,…,-2*T_offset,-T_offset,0,T_offset,2*T_offset,…,N*T_offset]和至少一个目标对象的持续时间偏移值索引T_index。
其中，上述a)至d)中的至少一项可以承载在如下中至少一项中：
盘点的控制信令；
查询的控制信令；
读取的控制信令；
发送查询Tag的身份标识的控制命令。
当Tag收到了Reader指示的上述a)至d)中的至少一项之后，则在D1时间内按照参数信息指示的内容进行传输，若Tag没有收到Reader反馈的上述a)至d)中的至少一项，则Tag不执行频偏调整和/或目标对象的传输时间调整，并采样默认的时域资源和频域资源，在D2时间内进行传输。可选地：D1的优先级高于D2的优先级。
因此，本申请的实施例，可以在Reader侧估计Tag的时域偏移和/或频率偏移，并将估计结果指示给Tag，Tag根据Reader的参数信息，调整相应的频域资源和/或时域资源，从而在蜂窝网络中，使得Tag在规定的频率资源上传输之后，Reader可以更好的调度和分配资源，并且降低同时发送或者接收的信号之间的干扰。
此外，需要说明的是，本申请的实施例，可以适用于Tag与gNB直接通信，以及UE辅助Tag与gNB之间的通信两种形式。
