Abstract
In connection with an RF communication system, exemplary aspects involve a method for use in a communication system in which a first system (e.g., 802.11) that is asynchronously based and which is susceptible to interference from a second system (e.g., synchronous-based LTE-CV2X). Such interference is due to the frequency spectrum used by the first and second systems overlapping. To mitigate interference issues, example methods spreads out the times for messages in the first system, based on information concerning occupancy of the channel, and transmitting them relative to the end of a cycled transmission allocated for use by the second system.
