ADAPTATION OF SECURE SOUNDING SIGNAL TO BANDWIDTH VARIATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18190906 titled 'ADAPTATION OF SECURE SOUNDING SIGNAL TO BANDWIDTH VARIATION

Simplified Explanation

- The patent application describes a system for adapting a secure sounding signal in communication devices. - The system includes a device that determines the negotiated bandwidth for communication with another device. - Based on the negotiated bandwidth, the device generates a first bit stream using a specific number of bits. - The device also generates a second bit stream to generate a random phase. - Using a combination of the first and second bit streams, the device determines a secure long training field (LTF). - The device then sends a frame to the other device, which includes the secure LTF. - The innovation allows for secure communication by adapting the sounding signal based on the negotiated bandwidth.

Original Abstract Submitted

This disclosure describes systems, methods, and devices related to adaptation of secure sounding signal. A device may determine a negotiated bandwidth to be used when communicating with a first station device. The device may determine a first bit stream used to generate a cyclic shift diversity (CSD) value based on the negotiated bandwidth, wherein a first number of bits is used for the first bit stream when a first negotiated bandwidth is used, and wherein a second number of bits is used for the first bit stream when a second negotiated bandwidth is used. The device may determine a second bit stream used to generate a random phase. The device may determine a secure a long training field (LTF) based on a combination of the first bit stream and the second bit stream. The device may cause to send a frame to the first station device, wherein the frame comprises the secure LTF.
