BSC是指BSC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该BSC设备的信息，是一种比较典型的无源物联设备。图2示出了BSC设备的结构示意图，如图2中的(a)所示，BSC发送设备主要包括以下主要模块：
天线单元21：用于接收射频信号、控制命令，同时用于发送调制的反向散射信号；
能量采集模块或供能模块22：用于BSC发送设备进行射频能量采集，或者进行其它能量采集，其中，该能量包括但不限于太阳能、动能、机械能、热能等；该能量采集模块或供能模块22可以给BSC发送设备中的其它所有模块进行供电。需要说明的是，能量采集模块或供能模块22也可以为电池供能模块，此时BSC发送设备为半无源设备；
微控制器23：用于控制基带信号处理、储能或数据调度状态、开关切换、系统同步等；
信号接收模块24：用于解调BSC接收设备或其它网络节点，发送的控制命令或数据等；
信道编码和调制模块25：用于在微控制器23的控制下进行信道编码和信号调制，并通过选择开关在微控制器23的控制下，通过选择不同的负载阻抗来实现调制；
存储器或传感模块26：用于存储设备的标识(Identity Document，ID)信息、设备的位置信息或传感数据等。
除了上述典型的构成模块之外，未来的BSC发送设备甚至可以集成隧道二极管放大器模块、低噪声放大器模块等，用于提升BSC发送设备的接收灵敏度和发送功率。
传统的射频识别系统中的BSC接收设备通常为阅读器，如图2中的(b)所示，BSC接收设备主要包括以下主要模块：
天线单元27：用于接收调制的反向散射信号；
反向散射信号检波模块28：用于对BSC发送设备发送的反向散射信号进行检波(包括幅度键控调制(Amplitude Shift Keying，ASK)检波、相位键控调制(Phase Shift Keying，PSK)检波、频率键控调制(Frequency Shift Keying，FSK)检波或正交幅度调制(Quadrature Amplitude Modulation，QAM)检波等)。
解调解码模块29：用于对检波出的信号进行解调制和解码，以恢复出原始信息流。
图3示出了BSC设备调制信号的原理示意图，如图3所示，BSC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Sin(t)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下述的公式(1)：
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Γ可实现对应的幅度调制、频率调制或相位调制。基于此，BSC设备可以为传统射频识别系统中的标签(即Tag)，或者是无源或半无源物联网(Passive/Semi-passive Internet of Things，Passive/Semi-passive IoT)设备。
未来的6G通信网络需要支持海量的万物互联，其中物联网设备数量将达到千亿级别，其连接密度相比5G提升了10-100倍，达到10-100个/m2的连接密度。海量的物联网设备对成本和功耗都提出了新的挑战。蜂窝网络化、低成本、低功耗甚至零功耗无源化是未来物联网设备发展的主要趋势。受限于网络节点的发送功率、双程链路衰减、储能电路的储能效率与储能容量、BSC设备的接收灵敏度、收发天线增益以及信号干扰的影响，BSC的前向和反向覆盖都面临较大的技术挑战。
目前，BSC系统可以分为单基地反向散射通信系统(Monostatic Backscatter Communication Systems,MBCSs)和双基地反向散射通信系统(Bistatic Backscatter Communication Systems,BBCSs)。图4示出了BSC系统架构的示意图，如图4中的(a)所示，MBCSs(例如传统射频识别系统)中包含BSC发送设备41(例如Tag)和读写器(即Reader)42，读写器42中包含电磁频率(Radio Frequency，RF)射频源和BSC接收端，其中RF射频源用于产生RF射频信号，以给BSC发送设备41供能；BSC发送设备41通过反向散射经过调制后的RF射频信号，从而读写器42中的BSC接收端在接收到该反向散射信号之后，可以进行信号解调。由于RF射频源和BSC接收端是在同一个设备(例如读写器42)中，因此称为MBCSs。在MBCSs系统中，由于从BSC发送设备发送的RF射频信号，会经过往返信号的信号衰减，会引起的双倍远近效应，因此使得信号的能量衰减较大，从而MBCSs系统一般用于短距离的BSC。如图4中的(b)所示，不同于MBCSs系统，BBCSs中的RF射频源43、BSC发送设备44和BSC接收设备45是分开的，从而可以避免往返信号衰减较大的问题。另外，通过合理的放置RF射频源43的位置，可以进一步提高BBCSs的性能。需要说明的是，环境反向散射通信系统也是 BBCSs的一种，但环境反向散射通信系统中的射频源可以是可用的环境中的射频源，例如，电视塔、蜂窝基站、WiFi信号、蓝牙信号等。
可以看出，采用BBCSs架构是提升BSC覆盖有效的方式之一，可以避免MBCSs中的双程信号衰减的问题。通过合理的放置射频源和BSC接收设备的位置，甚至部署专门用于射频供能的射频源，可以有效的提升BSC的传输覆盖。但在BBCSs中，由于接收信号是有用的反向散射信号和同频的直接链路干扰信号的叠加，且直接链路干扰信号的强度可能远大于反向散射信号强度，因此强直接链路干扰消除是反向散射通信中实现速率、覆盖、可靠性传输和大规模连接提升的技术前提。并且由于该直接链路干扰可能是经过调制的信号，且BSC接收设备通常不知道直接链路信号的调制特性，因此进行直接链路干扰消除的挑战更大，相同的问题同样存在于MBCSs中的自干扰消除。
为了有效的消除来自射频源的强直接链路干扰，研究人员基于射频载波信号的时域结构特性和频域结构特性，并联合反向散射基带信号设计，可以使BSC接收设备能够有效地消除强直接链路干扰。考虑用于射频载波信号是LTE和NR系统中广泛使用的正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)信号波形场景，研究者根据OFDM信号中存在循环前缀(Cyclic Prefix，CP)时域重复结构的特性，通过联合设计BSC设备中的差分类基带调制信号，在信道时延不超过CP长度的情况下能够有效的消除强直接链路干扰。除了利用OFDM时域上的重复结构，也可以利用OFDM频域上的保护带来进行干扰消除，通过基带信号等效频率搬移到不同的保护带来进行信号调制。相同的设计思想也可以扩展到未调制的单正弦波射频信号等。
在干扰消除中，BSC接收设备需要根据直接链路和反向散射级联链路的最小信道传输时延与最大时延扩展来确定判决阈值。其中，表示射频源到BSC接收设备的离散信道传输时延，表示射频源到BSC发送设备以及BSC发送设备到BSC接收设备级联信道的离散信道传输时延，fs表示信号的采样率；表示射频源到BSC接收设备的信道时延扩展，Lb＝[(dh1+dh2+τh1+τh2)fs]表示射频源到BSC发送设备以及BSC发送设备到BSC接收设备级联信道的信道时延扩展。另外，在获得各链路的信道传输时延和信道时延扩展之后，还可以用于确定射频载波的帧结构或基带信号的符号周期等。然而，目前尚缺乏有效的时延估计方法用于估计级联信道和直接链路的信道时延信息(包括信道传输时延和信道时延扩展)。
为了解决上述问题，在本申请实施例提供的时延信息估计方法中，第一设备可以根据第一目标配置信息，接收第二设备发送的第一目标信号，并根据第一目标信号，估计第一目标时延信息；且第一设备可以根据第二目标配置信息，接收第三设备发送的第二目标信号，并根据第二目标信号，估计第二目标时延信息；第一目标时延信息包括以下至少一项：第一时延信息和第二时延信息；第一时延信息与第二时延信息之和；其中，第一时延信息为第二设备和第三设备之间的信道时延信息，第二时延信息为第一设备和第二设备之间的信道时延信息；第二目标时延信息为第一设备和第三设备之间的信道时延信息。通过该方案，由于第一设备可以基于用于进行信道时延信息估计的配置信息，第二设备发送的第一目标信号，以及第三设备发送的第二目标信号，分别估计第二设备和第三设备之间的信道时延信息，第一设备和第二设备之间的信道时延信息，以及第一设备和第三设备之间的信道时延信息，因此第一设备可以有效地估计级联信道(即第一设备和第二设备之间的信道，以及第二设备和第三设备之间的信道)的时延和直接链路信道(即第一设备和第三设备之间的信道)的时延，从而可以通过估计得到的信道时延准确消除直接链路干扰信号的干扰。

下面结合附图，对本申请实施例提供的时延信息估计方法及其应用场景进行示例性地说明。
图9示出了本申请实施例提供的一种时延信息估计方法的示意图，如图9所示，用于各链路时延信息估计的帧结构包括：
(1)时间戳信息(例如第一时间信息、第二时间信息或第三时间信息)，即发送本信号的时间信息；
(2)源设备(即第三设备)ID信息或其它设备信息，若向BSC发送设备(即第二设备)发送信号，则源设备ID或其它设备信息作为可选，帧结构示例如图9中的(c)所示；
(3)前导序列，或目标设备预配置的参考信号；
(4)可选地，包括目标设备ID，帧结构示例如图9中的(a)所示；
(5)可选地，不包括目标设备ID，但帧为经过目标设备ID或相关信息加扰的信号，帧结构示例如图9中的(b)所示。
本申请实施例提供的时延信息估计方法的一种典型的应用场景是消除直接链路干扰，图10示出了估计出的时延信息应用于确定帧结构与符号周期的方法的示意图，为了有效地消除直接链路干扰，射频源设备(即第三设备)发送的信号需要满足：
(1)射频源设备发送满足如图10中的(a)所示的时域结构的载波信号s(t)：
(a)s(t)中包括极性和数据完全相同的两个时隙块(以时隙块为例，可以扩展到其它的时间单元)，组成一个基本时隙块，每个时隙中的数据长度为N，周期长度为Ts，且可以是随机或非随机的，其中，s(t)可以表示为下述的公式(2)：
(b)可选地，如图10中的(b)所示，每个两个时隙块是分布式的，中间间隔Q个或时长为Ta的其它数据单元，此时s(t)可以表示为下述的公式(3)：
(c)可选地，每个时隙内的数据可以是按照预设规则生成的非随机或随机序列；
(d)为了保证消除干扰的性能，Ts或是N必须满足：N+D>L；
其中，为最小信道传输时延，为最大时延扩展。
对于BSC发送设备(即第二设备)，则通过调整BSC调制信号的符号周期Tb与载频信号的周期Ts，并满足：Tb＝2Ts；
另外，可以定义BSC基带信号采用Miller编码，如图10中的(c)所示，若发送比特B＝0，则基带信号b(t)为：b(t)＝0，0≤t≤Tb；若发送比特B＝1，则基带信号b(t)为：
可选地，估计出的时延信息还可以应用于确定判决值。在以OFDM为射频信号的BBCSs中，基于射频源设备(即第三设备)发送的OFDM信号中的CP的重复结构以及BSC发送设备(即第二设备)的Miller码基带信号，若发送比特B＝0，则基带信号波形为：
b[n]＝1，n＝0，…，K(N+Nc)-1；若发送比特B＝1，则基带信号波形为：
其中N为OFDM符号的长度，Nc为CP的长度。
不失一般性，假设k＝1。对于BSC接收设备(即第一设备)，将接收到直接链路干扰信号yd[n]和 反向散射信号yb[n]。根据CP重复结构特性，直接链路干扰信号yd[n]满足：
yd[n]＝yd[n+N]，n＝Lh1-1，…，Nc+Dh1-1；
同样的，反向散射信号yb[n]满足：
若发送比特B＝0，则
若发送比特B＝1，则
然后利用yd[n]和yb[n]的重复结构，构建如下差分信号：
若发送比特B＝0，则
若发送比特B＝1，则
其中，y[n]＝yb[n]+yd[n]+w[n]为BSC接收设备的接收信号；
且v[n]＝w[n]-w[n+N]。
从而所构建的判决阈值为：其中，阈值γ是一个与CP长度Nc，最小信道时延D以及最大时延扩展L相关的值。
