A prioritized random access with discriminative power ramping step size
Hyu-Dae Kim, Sunghong Wie, Dong‐Ho Cho · 2002
Power ramping makes the access more likely to succeed in a contention, so power ramping can be modified to support multi-class services in a random access channel. In this paper, we introduce discriminative router ramping into a slotted-ALOHA channel and 3GPP (Third Generation Partnership Project) common packet channel. The proposed scheme serves the high-priority service more rapidly and more efficiently with few defects in both channels.
