Abstract
Disclosed herein are a systems and method for using frequency tones to schedule full-duplex communications between at least two full-duplex communication nodes. Communication nodes having data to transmit send, as part of two contention rounds, two separate and randomly selected frequency tones. In the first contention round, all nodes having data to transmit simultaneously transmit a frequency tone. Based on these first frequency tones, groups of nodes are formed. Each group of nodes in turn transmits a second set of frequency tones, and a schedule of full-duplex communications is created based on the second frequency tones.
