Claim of US Patent No. 11,071,093


1. A method of reducing interference in a Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) communication system wherein a communication link is established between a transmitter and a receiver by monitoring a channel for transmissions for a collision avoidance duration and only transmitting after a channel has been idle for the collision avoidance duration, the method comprising:determining an interference level at the transmitter for a transmission from the transmitter to the receiver;
comparing the determined interference level to a threshold value, wherein the threshold value is adjusted dynamically based on a type of the transmission; and
when the determined interference level does not exceed the threshold value, transmitting from the transmitter to the receiver on a channel that has been idle for a collision avoidance duration, and
when the determined interference level exceeds the threshold value, performing a link adaptation,
wherein performing the link adaptation comprises:identifying at least two channels that are idle for the collision avoidance duration,
applying a channel bundling by transmitting from the transmitter to the receiver on the at least two channels after the collision avoidance duration,

wherein the collision avoidance duration comprises an inter-frame space and a backoff period associated with each channel.
