- Abstract
- In this paper, we consider the queueing performance of a subscriber station for IEEE802.16e random access protocol with piggyback operation and an ARQ. The random access protocol of IEEE802.16 is based on orthogonal frequency-division-multiple-access and code-division-multiple-access with time division duplexing mode. It is a type of demand-assigned multiple access with piggyback, in which a bandwidth request can be allowed either before transmitting data or at the end of data transmission. The queueing model of our interest is an M/G/1 type queue with set-up times and exhaustive service, which is solved by a generating function approach. From the queueing analysis, we obtain the piggyback probability and the output process from the queue. The performance is presented in terms of the first and second moments of queue-size by varying number of subscriber stations in a cell, number of PN codes for bandwidth request ranging and number of slot-subchannels. © 2006 IEEE.
