Roberto Padovani, Paul E Bender, Peter J Black, Matthew S Grob, Jurg K Hinderling, Nagabhushana T Sindhushayana, Charles E Wheatley III: Method and apparatus for high rate packet data transmission. Qualcomm Incorporated, Philip R Wadsworth, Kent D Baker, Sandra L Godsey, June 3, 2003: US06574211 (505 worldwide citation)

In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate su ...
