Özet
The IEEE 802.16 standard defines physical (PHY) and MAC layers of Broadband Wireless Access (BWA) systems. The uplink transmission of Subscriber Stations (SS) are determined by Base Station (BS) with sending uplink map (UL-MAP) in point to multipoint networks. The UL-MAP is sent in the downlink sub frame and its size affects downlink data capacity. In this paper, we introduce a new scheme to minimize MAC overhead due to UL-MAP size with using UL-MAP Extended Information Element (IE) to send future periodic fixed size grants for the connections whose scheduling service type is Unsolicited Grant Service (UGS). We show that our proposed scheme is superior to its conventional counterpart when there are high numbers of SS with UGS connections in terms of cell throughput via OPNET simulations. © 2008 by Boǧaziçi University.
