Towards an optimal transmission of SDUs in IEEE 802.16e WiMAX systems

Physical and Medium Access Control criteria for the optimal Medium Access Control protocol data unit size in Automatic Repeat Request‐enabled connections in IEEE 802.16e/ WiMAX systems

“…This paper differs from in two main aspects. First, in this paper we assume data blocks and not a bit stream, which requires a new style of computations.…”

“…p is bigger for longer FEC blocks. In this paper, we assume that all the FEC blocks are of the same size and that p is similar for all the FEC blocks of a transmission frame, that is, there is no correlation dependency between the success probabilities of FEC blocks of the same size in a transmission frame .…”

“…However, they do not consider the issue of efficient transmissions in the bursts. The only studies that we are aware of, which deal with the mutual influence between the PHY layer budding blocks (FEC blocks) and the MAC layer PDUs in IEEE 802.16e/WiMAX systems, are . In , the optimal size of PDUs is computed, given fixed length FEC blocks and the transmission of a bit stream.…”

“…In , the optimal size of PDUs is computed, given fixed length FEC blocks and the transmission of a bit stream. However, the PDU size in is not accurate because it should have been rounded off to an integral number of FEC blocks, as was shown later in . In , the authors investigate the optimal division of a burst into PDUs such that the burst goodput is maximized, assuming a bit stream.…”

In , the authors investigate the optimal division of a burst into PDUs such that the burst goodput is maximized, assuming a bit stream. In , the authors, based on , investigate the question of which are the most efficient burst sizes, that is, the sizes that optimize the goodput.…”
