This instruction relates to wireless sensing in general. More specifically, it relates to methods, systems, and apparatus for performing wireless sensing measurements and reporting. With the proliferation of Internet of Things (IoT) applications, billions of consumer electronics, phones, smart devices, security systems, environmental sensors, vehicles and buildings, and other wirelessly connected devices will transmit data and communicate with each other or with people, enabling everything to be constantly measured and tracked. Among the various approaches to measuring what is happening in the surrounding environment, wireless sensing has been attracting increasing attention in recent years for the ubiquitous deployment of wireless devices. Furthermore, since human activity affects the propagation of wireless signals, understanding and analyzing how wireless signals respond to human activity can reveal a wealth of information about that activity. As more bandwidth becomes available in next-generation wireless systems, wireless sensing will enable many smart IoT applications that are currently only imaginable in the near future. This is because wider bandwidth allows us to see more multipaths even in scattered environments such as indoors or in metropolitan areas, and treat them as hundreds of virtual antennas/sensors. While several technical standards, such as IEEE 802.11bf, support wireless sensing, many details of wireless sensing, such as how to perform wireless sensing measurement and reporting, are still not standardized. Therefore, efficient and effective methods for measuring and reporting wireless sensing data are desired. This instruction relates to wireless sensing in general.
