Abstract
A system for performing transmit power and admission control for a satellite based wireless communication systems. Admission control uses centralized admission and distributed admission controls. Centralized admission control uses a maximum persistence value broadcasted from a hub to terminals. Persistence is the probability that a transmission will timely occur. Each terminal transmits a persistence that is no greater than the maximum persistence value. If the transmission fails, the transmission is repeated using the same probability. Lowering the persistence introduces a delay for alleviating congestion. Power control is performed using centralized and distributed power control. Centralized power control uses power control commands transmitted from the hub to each terminal. When an acknowledge is not received, a backoff and recovery procedure is performed. Distributed power control is performed during the recovery process when a terminal fails to receive an acknowledgment message after a predetermined number of attempts.
