Statistical quality-of-service analysis in multiuser diversity system enhanced with queue information

In recent years, the scheduling scheme of exploiting multiuser diversity gain has attracted much attention for the purpose of efficient spectrum utilisation. The authors consider the problem of analysing the quality of service in the scheduler extracting multiuser diversity gain. The authors use not only the channel state information but also the queue information in determining the optimal user to be scheduled. Through queuing analysis, the guaranteed rate, the average delay and the delaybound violation probability can be calculated.©The Institution of Engineering and Technology 2013.
