Abstract :
Forward link data throughput performance of a high data rate wireless access system is presented. On the forward link of the proposed system data is transmitted to different access terminals (AT) in a TDM fashion. The rate transmitted to each AT is variable and depends on each AT´s measured SINR. ATs send to the access points (AP) the index of the highest data rate which can be received reliably. A scheduler at the AP determines the next terminal to be served based on the reported data rate requests from the terminals and the amount of data that has already been transmitted to each terminal. A cell layout of 19 3-sector and 6-sector hexagonal cells is considered. The throughput of the forward link of the embedded sector is simulated for stationary terminals
