Subscriber devices are used as parts of wireless communication systems. Inherent in the operation of time division duplex (TDD) devices is a fundamental "turn-around" time which is the amount of time it takes for the devices to switch from a receive to a transmit mode and vice versa. Because of the turn-around time an amount of inefficiency is introduced into the speed of operation of the communication system. Base stations and infrastructure equipment for the wireless service are typically much more complex than the subscriber devices; therefore, the subscriber devices normally have larger turn-around times than the infrastructure equipment and the operation of the system is limited by the slowest subscriber device. More particularly, a guard time is set in the communication system in order to support the subscriber device with the slowest turn-around time. The speed of operation of the communication system is dependent on and determined by the turn-around time of the slowest subscriber device in the communication system. Therefore, the capacity of information throughput of the communication system is greatly reduced.
Thus, there is a need for a wireless communication system that provides a more efficient and greater information throughput by taking into account the turn-around time of the subscriber devices of the wireless communication system.
