图10示出了一种Wi-Fi通信链路的射频(Radio Frequency)和基带(Baseband，BB)模块示意图，包括一个发送机(Transmitter，Tx)和一个接收机(Receiver，Rx)。按照发送信号的顺序介绍，发送机内含有基带、数模(D/A)转换器(Digital Analog Converter，DAC)、混合器(Mixer)、功率放大器(Power Amplifier，PA)和天线(Antenna)。按照接收信号的顺序介绍，接收机内含有天线、低噪声放大器(Low Noise Amplifier，LNA)、混合器、可变增益放大器(VariableGainAmplifier，VGA)、D/A转换器和基带，其中， 低噪声放大器和可变增益放大器用于自动增益控制(Automatic Gain Control，AGC)。
Wi-Fi/WLAN感知关心的是发送机天线和接收机天线之间的物理信道，这个物理信道会受到墙壁地板、运动物体等物理环境的影响。但是，Wi-Fi/WLAN设备原本用于传输数据，需要关心的是发送机发送的基带符号与接收机接收的基带符号之间的关系，所以其本来具备的信道估计功能所感知的信道不仅仅包括物理信道，而是一种复合信道，包括发送机内部的发送链路和接收机内部的接收链路，也即复合信道是从发送机的基带到接收机的基带的完整链路，在《通信原理》中也称此复合信道为调制信道。因此，当使用Wi-Fi/WLAN来感知物理环境的变化时，若发送机的发送功率和发射天线辐射模式在此期间发生变化或者接收机的接收增益，即自动增益控制增益，和接收天线辐射模式发生变化，就会导致对物理信道本身的感知产生干扰，降低感知的准确度。
基于上述问题，本申请基于11bf Draft 0.1的内容提出了改进方案，在感知测量的设置、测量、上报阶段中修改或新定义的若干元素和帧格式来传递相关信息，以消除或者补偿发送功率变化、发射天线辐射模式变化、AGC接收增益、接收天线辐射模式变化对感知测量结果的干扰。

本申请在感知测量的设置阶段、测量阶段、和上报阶段中修改或新定义了相关元素和帧格式来传递相关信息。接下来介绍三个阶段中的若干元素和帧格式：

另外，在基于触发帧的感知测量设置中，该字段不能取值为1。原因在于，基于触发帧的感知测量中R2I方向的NDP使用的协议数据单元(Physical Layer Protocol Data Unit，PPDU)为TB PPDU，而TB PPDU的传输本来就存在上行发送功率控制机制，触发帧的每个用户信息(User Info)中存在上行目标接收功率(UL Target Receive Power)字段，使得感知接收设备(如AP)接收到的多个TB PPDU的接收功率相近从而便于感知接受设备进行解调。所以，在现有的UL TB PPDU功率控制的基础上再指定感知发送设备(如STA)的发送功率是矛盾的。
2表示感知响应者反馈R2I发送功率：感知响应者将发送NDP的发送功率上报给感知发起者，感知发 起者依据其收到的R2I NDP发送功率和参考CSI对其计算得到的CSI进行补偿；
3表示保留该字段。

·感知响应设备将接收NDP时所使用的AGC增益发送给感知发起设备，感知发起设备根据AGC增益和参考CSI对测量得到的CSI进行补偿。

其中，
0表示实测CSI：指示该感知测量报告元素中的“感知测量报告”字段携带的数据为实时测量得到的CSI数据，即在与一个感知测量实例ID相关的感知测量实例中基于NDP测得的CSI数据；
1表示与R2I发送功率相关的参考CSI：指示该感知测量报告元素中的“感知测量报告”字段携带的数据为一组参考CSI数据，用于感知发起者实现R2I发送功率CSI补偿。该参考CSI与感知响应者发送R2I NDP的发送功率相关，一组参考CSI数据对应一个发送功率等级(由“R2I发送功率”字段指示)，是感知响应设备预先存储在本地缓存中的固定数据，而非实时测量得到的CSI数据。
2表示与AGC增益相关的参考CSI：指示该感知测量报告元素中的“感知测量报告”字段携带的数据为一组参考CSI数据，用于感知发起者实现AGC增益CSI补偿。该参考CSI与感知响应者接收I2R NDP时使用的AGC增益等级相关，一组参考CSI数据对应一个AGC增益等级(由“AGC增益”字段指示)，是感知响应设备预先存储在本地缓存中的固定数据，而非实时测量得到的CSI数据；
3表示保留该字段。
应当理解，参考CSI数据类型的编码格式与实测CSI数据类型完全相同，唯一的区别在于，实测CSI数据为一次真实的感知测量的结果数据，而参考CSI数据为感知响应设备预先配置好的参考数据，其目的仅仅在于将感知响应设备中R2I NDP发送功率对CSI的非线性频率响应特性和AGC对CSI的非线性频率响应特性告知感知发起者，从而分别辅助感知发起者完成R2I发送功率CSI补偿和AGC增益CSI补偿。
当“参考CSI类型”字段取值为1或2时，在与同一个感知测量设置ID相关的多个感知测量实例中，首先出现的若干个感知测量实例中的感知测量上报帧中的感知测量报告元素中将仅携带参考CSI数据，即感知测量报告元素中的“参考CSI类型”字段的取值为1或者2。感知测量实例的具体个数取决于感知响应者预先配置的参考CSI的数据量的大小，与实现相关。当参考CSI数据传输结束后，接下来的感知测量实例才开始携带当前感知测量实例中真实测量得到的CSI数据，即感知测量报告元素中的“参考CSI类型”字段的取值为0。
上述图14至17中字段下方的数字代表该字段的位数(Bits)或字节数(Octets)。
本申请中，感知测量方法按照补偿模式进行分类至少可以分为三类，分别为：

本实施例中感知发起者和感知响应者均为感知发送者和感知接收者，即双方设备均既发送NDP也接收NDP。
图18示出了本申请一个示例性实施例提供的感知测量方法的流程图，该方法包括如下步骤中的至少部分步骤：

其中，I2R发送功率CSI补偿模式取值为0，R2I发送功率CSI补偿模式取值为0，指示I2R和R2I的感知测量结果都无需进行发送功率的CSI补偿。
步骤182：感知响应者向感知发起者发送感知测量设置响应帧；
步骤183：感知发起者向感知响应者发送感知测量宣告帧；
步骤184：感知发起者向感知响应者发送I2R NDP；
步骤185：感知响应者向感知发起者发送R2I NDP；
步骤186：感知发起者向感知响应者发送感知测量上报请求帧；
步骤187：感知响应者向感知发起者发送感知测量上报响应帧；
