1. A method comprising:
- receiving a first frequency tone indicating a first request to transmit first data from a communication node;
receiving a second frequency tone indicating a second request to transmit the first data from the communication node, wherein a timing of the second request to transmit the first data is determined based on the first request;
determining a schedule based on the second request; and
receiving, on a frequency channel, the first data from the communication node while transmitting, in full duplex, second data to the communication node on the frequency channel according to the schedule.

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.
