Executive Summary

The authors consider one of the latest features included in the Release 9 of the GSM/EDGE standard: the Orthogonal Sub Channel (OSC) transmission scheme. OSC aims at doubling the cell capacity by multiplexing two co-cell users on the same radio resource. In this paper, they deal with the challenge of finding the optimum pairing strategy among co-cell OSC users exploiting the Adaptive QPSK (AQPSK) modulation in both up- and down-link scenarios. The aim of the proposed scheduling algorithm is to find the best association among the users and the available OSC logical channels, and select the optimum transmitting powers. The criterion for optimization is the minimization of the overall transmitted power constrained to service quality targets.
