本公开实施例中,无线局域网感知的流程可以是:发起设备发起无线局域网感知(例如,发起无线局域网感知会话),可能存在着多个响应设备对其进行响应。
其中,发起设备和响应设备可以包括但不限于:蜂窝电话、智能电话、可穿戴设备、计算机、个人数字助理(PDA)、个人通信系统(PCS)设备、个人信息管理器(PIM)、个人导航设备(PND)、全球定位系统、多媒体设备、物联网(IoT)设备等。

虽然在上述描述中客户端作为发起设备,AP作为响应设备,然而本 公开不限于此,例如,AP可以作为发起设备,客户端可以作为响应设备。此外,发起设备和响应设备的数目不做限制。
在发起设备和响应设备建立感知会话过程中,需要协商与无线局域网感知相关的各项参数。本公开实施例提供了一种通信方法、装置、设备以及存储介质,用于使发起设备和响应设备在此过程中协商各自对应的NDP帧的承载带宽。

其中,HE对应于802.11n标准协议,VHT对应于802.11ac标准协议,EHT对应于802.11be标准协议。即带宽子域可用于指示发起设备在支持不同的标准协议时I2R对应的NDP帧的可能承载带宽。
其中,带宽子域在通过相应的标识位指示上述任一种承载带宽时,相应的标识位对应于不同的字段值,且上述任一种承载带宽对应的标识位的字段值在此不做限制。如表1所示:
