Abstract

Dynamic time-frequency domain packet scheduling algorithms in the shared channel of downlink Orthogonal Frequency Division Multiple Access (OFDMA) systems have been shown to achieve high multi-user diversity scheduling gains. However, the flexibility is obtained at the cost of additional control signaling for which the availability of resources is limited. This article addresses the effects of control signaling resources limitation as well as the effects of terminal control signaling decoding errors on the performance OFDMA packet scheduling algorithms.
