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信号检测和发送方法进行详细地说明。
如图2所示，本申请实施例提供一种信号检测方法200，该方法可以由终端执行，换言之，该方法可以由安装在终端的软件或硬件来执行，该方法包括如下步骤。
S202：终端接收第一信号，所述第一信号包括第一数据域和第二数据域，所述第一数据域与所述第二数据域关联，所述第一数据域的数据为所述第二数据域的数据中的部分数据的重复。
该实施例中，第一数据域与第二数据域关联，所述第一数据域的数据为所述第二数据域的数据中的部分数据的重复，终端可以基于第一数据域来对第二数据域进行检测等。
可选地，所述第一信号为低功耗唤醒信号(Wake Up Signal，WUS)。相关技术中的WUS结构是preamble+数据域，该实施例中的WUS可以仅存在数据域而不包括preamble。该实施例通过重新设计WUS的结构，使其包括第一数据域和第二数据域，第一数据域与第二数据域关联，所述第一数据域的数据为所述第二数据域的数据中的部分数据的重复。这样，终端可以基于第一数据域检测第二数据域，保证了终端对WUS信号检测的准确率或正确性。
可选地，所述第一信号可以为信标信号，该信标信号不包括preamble(beacon without preamble)，该实施例通过重新设计信标信号的结构，使其包括第一数据域和第二数据域，第一数据域与第二数据域关联，所述第一数据域的数据为所述第二数据域的数据中的部分数据的重复。这样，终端可以基于第一数据域检测第二数据域，保证了终端对信标信号检测的准确率或正确性。
本申请实施例提供的信号检测方法，终端接收第一信号，第一信号包括第一数据域和第二数据域，第一数据域与第二数据域关联，所述第一数据域的数据为所述第二数据域的数据中的部分数据的重复，保证了终端对第一信号检测的准确率或正确性。
对于以上提到的“保证了终端对第一信号检测的准确率或正确性”，以下将对其进行解释说明。例如，终端通过检测第一数据域的数据可以得到一个判决门限，通过检测第二数据域的数据可以得到另外一个判决门限，进而综合这两个判决门限来检测第二数据域的数据，相对于仅通过检测第二数据域得到的判决门限来检测第二数据域而言，有利于提升第二数据域的数据检测的准确率或正确性。
可选地，所述第一数据域与所述第二数据域关联包括：所述终端根据所述第一数据域的检测来辅助所述第二数据域的检测。该实施例例如，终端可以基于第一数据域得到比较 器的判决门限，进而通过该判决门限来检测第二数据域，有利于提升第一信号的数据域判决的准确性。以第一信号是OOK信号序列(包括多个0和1的序列)为例，当终端的接收机收第一信号时，可以基于接收第一数据域的数据得到判决门限，基于上述判决门限来检测第二数据域的数据，即检测发送端发送的比特是0或1。
可选地，第一数据域的数据可以是第二数据域中部分数据的多次重复，例如，第一数据域的长度是2比特，第一数据域的数据是第二数据域的第一个比特的数据的2次重复。又例如，第一数据域的长度是4比特，第一数据域的数据是第二数据域的前2个比特的数据的2次重复，或者，第一数据域的数据是第二数据域的第一个比特的数据的4次重复。
可以理解，重复的数据所包含的比特数大于或等于1，还可以小于或等于相关技术中前导码的比特数量，通常，重复数据所包含的比特数越多，得到的判决门限越准确。
本申请各个实施例中，第一数据域的长度可以小于相关技术中WUS信号的前导码的比特数量，有利于降低第一信号的负载。
可选地，所述第一数据域和第二数据域的关联关系可以是网络侧设备配置的或协议预定义的。
可选地，所述第一数据域与所述第二数据域存在如下至少一项的关联关系：检测关联，用途关联。
所述检测关联包括：所述终端根据所述第一数据域的检测来辅助所述第二数据域的检测。
所述用途关联包括：所述第一数据用于所述第二数据的如下至少之一：时频偏纠正，自动增益控制(Automatic Gain Control，AGC)调整，模数转换器(Analog-to-Digital Converter，ADC)调整，判决门限调整。
在一个例子中，所述第一数据域与所述第二数据域存在检测关联关系，S202还可以包括如下步骤：所述终端基于所述第一数据域检测所述第二数据域。
在一个例子中，所述第一数据域与所述第二数据域存在用途关联关系，S202还可以包括如下步骤：所述终端基于所述第一数据域对所述第二数据域执行如下至少之一：时频偏纠正，AGC调整，ADC调整，判决门限调整。
以上各个实施例中，所述第一数据域与所述第二数据域还可以存在如下至少一项的关联关系：时域位置关联，频域位置关联；其中，所述时域位置关联包括：所述第一数据域的时域位置在所述第二数据域的时域位置之前，且所述第一数据域的时域位置与所述第二数据域的时域位置相邻；所述频域位置关联包括：所述第一数据域的频域位置与所述第二数据域的频域位置相同或存在第一频差。即，在该实施例中，所述第一数据域与所述第二数据域的时域位置关系满足：所述第一数据域的时域位置在所述第二数据域的时域位置之前，且所述第一数据域的时域位置与所述第二数据域的时域位置相邻，和/或，所述第一数据域与所述第二数据域的频域位置关系满足：所述第一数据域的频域位置与所述第二数据域的频域位置相同或存在第一频差。
可选地，所述第一数据域的长度为第一长度，所述第一长度由一个或多个特定值组成。例如，第一长度由一个或多个特定值a1,a2,…,an组成，所述an来自特定集合。
在一个例子中，所述第一长度可以是网络侧设备配置的或预定义的。
在一个例子中，所述第一长度与所述第二数据域的第二长度相关，例如，第一长度与第二数据域的第二长度存在固定比例关系，或存在固定差值关系，具体例如，第二长度是第一长度的N1倍，N1是正数，或第二长度比第一长度多N2个符号，N2是正整数。
可选地，所述第一数据域的数据为：所述第二数据域中第一时间单元集合的数据的重复；或者，所述第一数据域的数据为：所述第二数据域中第二时间单元集合的数据的重复；其中，所述第一时间单元集合包括一个或多个连续的时间单元；所述第二时间单元集合包括多个离散的时间单元。
该实施例中，网络侧设备可以将第二数据域中的第一时间单元集合复制到第一数据域的起始位置。进一步的，第二数据域中多个第二时间单元集合复制到第一数据域的起始位置。需要说明的是，上述复制指的是，第一数据单元的内容为第二数据单元的前n个时间单元上内容的复制内容。
可选地，所述第一时间单元集合包括的时间单元的个数是网络侧设备配置的或协议预定义的。可选地，所述第二时间单元集合包括的时间单元的个数是网络侧设备配置的或协议预定义的。
以上提到的时间单元的单位可以为符号，时隙，秒，微秒，毫秒，帧，半帧等。可选的，所述符号为正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，还可以为幅移键控(Amplitude Shift Keying，ASK)符号，还可以为二进制启闭键控(On-Off Keying，OOK)符号。

可选地，第一信息可以是LP-WUR比较器的判决门限。以低功耗唤醒信号是OOK信号序列(包括多个0和1的序列)为例，当终端的LP-WUR接收低功耗唤醒信号时，可以基于上述判决门限来检测发送端发送的比特是0或1。
该实施例中，第一信息可以由第二信号携带，或者，终端可以基于第二信号间接得到第一信息。例如，第一信息与第二信号的类型相关，在终端接收到的第一类型的第二信号时，得到的第一信息为信息A；在终端接收到的第二类型的第二信号时，得到的第一信息为信息B；等等。
该实施例中的低功耗唤醒信号可以仅存在数据域而不包括前导码。
本申请实施例提供的信号检测方法，终端接收信标信号或SSB，根据与信标信号或SSB相关的第一信息检测低功耗唤醒信号，在低功耗唤醒信号不包括前导码的情况下，保证了终端对低功耗唤醒信号信号检测的准确率或正确性。
在其他的实施例中，在低功耗唤醒信号周期性发送的情况下，该实施例也可以利用低功耗唤醒信号来检测信标信号，该信标信号可以仅存在数据域而不包括前导码。
可选地，所述第一信息满足如下至少一项：1)所述第一信息由所述第二信号的数据域携带；2)所述第一信息由所述第二信号的前导码携带；3)所述第一信息与所述第二信号的类型相关，例如，所述第一信息与第二信号的类型存在映射关系。

可选地，所述第二信号为SSB；其中，所述终端接收第二信号包括：在所述终端处于低功耗唤醒状态时，所述终端接收SSB；所述终端根据所述第二信号相关的第一信息检测第三信号包括：在所述终端处于低功耗睡眠状态时，所述终端根据所述第二信号相关的第一信息检测第三信号。该实施例中，终端在低功耗唤醒状态下通过主接收机接收SSB，在低功耗睡眠状态时，通过LP-WUR检测第三信号。
需要说明的是，本申请各个实施例提到的终端可以包括主接收机(或称主模块)和低功耗唤醒接收机(LP-WUR)两部分，终端的低功耗唤醒状态可以是：主模块处于工作状态，LP-WUR处于睡眠状态。终端的低功耗睡眠状态可以是：主模块处于睡眠状态，LP-WUR处于工作状态。

以上结合图3详细描述了根据本申请实施例的信号检测方法。下面将结合图5详细描述根据本申请实施例的信号发送方法。可以理解的是，从网络侧设备描述的网络侧设备与终端的交互与图3所示的方法中的终端侧的描述相同或相对应，为避免重复，适当省略相关描述。
图5是本申请实施例的信号发送方法实现流程示意图，可以应用在网络侧设备。如图 5所示，该方法500包括如下步骤。

可选地，作为一个实施例，所述第二信号与所述第三信号之间的间隔小于第一相关时长T。
为详细说明本申请实施例提供的信号检测方法，以下将结合几个具体的实施例进行说明。
实施例一
如图6所示，WUS信号的结构中只有数据域，因此将WUS数据域中的部分符号复制后放在原WUS数据的前面，组合成一个新的结构，即第一数据域和第二数据域，接收端(终端)基于第一数据域检测第二数据域。
实施例二
在一种方案中，WUS信号采用OOK调制方式，此时第一数据域为确定长度的特定值，其中，an取值为0或1，an来自特定集合，特定集合为{0,1}。
假设第二数据域的长度为100个符号，特定值长度通过以下方法之一确定：
1)网络配置或协议预定义5个符号。
2)与第二数据域的长度相差N1倍，其中N1＝1/10，即特定值长度为10个符号。
3)与第二数据域的长度相差N2个符号，其中N2＝80，即特定值长度为20个符号。
以上述2)为例，特定值长度为10个符号，且由0和1组成的，则该特定值可以为0101010101。
实施例三
基于某下行信号的信息对WUS的数据展开检测，以beacon信号为例。
在一种方案中，如图7所示，信标信号(beacon信号)周期性发送，结构中包含前导码和数据域两部分，在数据域中插入第一信息，用以指示WUS信号的检测。
在另一种方案中，信标信号不通过数据域显性指示第一信息，而是通过预定义的方式将第一信息与信标信号的类型绑定，即隐式指示，终端通过判断接收的beacon信号即可检测对应的低功耗唤醒信号。
在一种方案中，如图8所示，信标信号按照固定周期发送，WUS信号周期或者按需 发送。其中信标信号1和信标信号2检测成功，信标信号3检测失败，WUS信号1和WUS信号2按需发送。WUS信号1和WUS信号2分别对应终端在根据第二信号的第一信息解调第三信号的两种方法。
方法一：第一信息解析成功后直接使用第一信息检测第三信号。因为信标信号1解调成功，在对WUS信号1检测时可以使用信标信号1中携带的第一信息直接检测WUS信号1。
方法二：第二信号接收失败和/或第一信息解析失败后，使用历史第一信息检测第三信号。由于信标信号3解调失败，无法获取第一信息内容，此时采用历史时刻的第一信息的方式，即针对WUS信号2的检测依赖于信标信号2中的第一信息，或综合考虑信标信号1和信标信号2的第一信息，最终联合检测WUS信号2。
