Abstract
In this paper, we propose and evaluate the performance of CDMA(Code Division Multiple Access) based high speed packet data service MAC(Medium Access Control) protocol for IMT2000 system. This proposed MAC supports smooth evolution from conventional IS-95 based system to IMT2000. Also, proposed MAC supports connection-less packet transmission over wireless channels. Channel utilization is maximized by using discontinous transmission mode technology and efficient channel re-use property. Most of all, 5 ms-size message structure based control mechanism provides fast MAC management scheme. Then Sleep-mode based physical channel control function is provided to support power save effect and fast channel activation method. Also, channel related information is minimized by using state transition characteristics of propose MAC. Especially, proposed MAC is admitted by TR45.5 as a part of cdmaOne standard, and proposed to ITU-R as a CDMA based IMT2000 radio transmission technology candidate.
