COORDINATION OF CROWD SENSING USING RADIO FREQUENCY SENSING FROM MULTIPLE WIRELESS NODES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17848582 titled 'COORDINATION OF CROWD SENSING USING RADIO FREQUENCY SENSING FROM MULTIPLE WIRELESS NODES
Simplified Explanation
Techniques are provided for coordinating RF sensing by multiple wireless devices to reduce interference. The devices obtain orthogonality information for transmitting and receiving RF sensing signals. This information can be provided by a server, another device, or a group of devices. The devices use this information to transmit and receive RF sensing signals that are orthogonal to signals from nearby devices. The orthogonality can be in spatial, time, frequency, or code domains. The devices perform RF sensing operations based on this coordination information and report the results.

Original Abstract Submitted
Techniques are provided for coordinating radio frequency (RF) sensing by a plurality of wireless devices. Wireless devices obtain RF sensing coordination information that includes orthogonality information for transmission and reception of RF sensing signals to reduce or eliminate interference between RF sensing by different devices. The orthogonality information may be provided by a server, another wireless device, or a group of wireless devices. The orthogonality information is used by a wireless device to transmit and receive RF sensing signals that are orthogonal to RF sensing signals transmitted and received by other nearby wireless devices. The orthogonality information may be for orthogonality in a spatial domain, time domain, frequency domain, code domain, or some combination of these. The wireless devices perform RF sensing operations based at least in part on the RF sensing coordination information and report the RF sensing results.
