Abstract

Systems and methods for accommodating flexibility in sensing transmissions are provided. Wi-Fi sensing systems include sensing devices and remote devices configured to communicate through radio-frequency signals. Initially, a sensing device transmits a sensing configuration message to a remote device. The sensing device receives a sensing configuration response message in response to the sensing configuration message. In an example, the sensing configuration response message may include a transmission capability indication associated with the remote device. The transmission capability indication includes a flexibility indication that the remote device supports flexibility.
