Comparison of link quality control strategies for packet data services in EDGE

EGPRS is the packet radio service of EDGE, the common evolutionary path for the two second generation cellular standards GSM and TDMA/136. In this paper, methods for adapting the transmission rates and robustness to different environments and to the sometimes rapidly varying radio conditions experienced in such systems are evaluated. A discussion comparing different solutions together with supporting simulation results lead to the proposed solution for EGPRS.
