On The Effect of Channel-Aware Scheduling to CDMA Uplink Capacity

Abstract

We show that channel-aware scheduling can significantly improve the capacity of CDMA uplink when compared to round robin scheduling. Using both analysis and simulations we quantify the capacity increase due to channel-aware scheduling in terms of reduction in intercell interference. The scheduling approaches can be used, e.g., within the current cdma2000 and WCDMA systems. Finally, we demonstrate that soft handover reduces the benefit from channel-aware scheduling and base station antenna gain properties are important for the scheduling performance
