Abstract: In 5G and 6G, users at high traffic density can be forced to delay transmissions to avoid collisions, and by convention the delay interval is increased upon each instance. This convention penalizes those who have been delayed the most, resulting in excessive latency, gross unfairness, and the blocked-node problem whereby certain users are denied access indefinitely. Disclosed are improved protocols whereby users can delay by shorter intervals upon each successive backoff, thereby reducing overall delays, greatly reducing message failure rates, and providing enhanced fairness overall. The protocols detailed herein can enable wireless users to communicate with fewer and shorter interference delays, while the base station can clear the waiting list sooner, and network operations can be improved generally. Numerous additional aspects are disclosed.
