—In this paper, call admission and code allocation schemes are proposed to provide service differentiation in the forward link of wideband code-division multiple-access (WCDMA) systems. In particular, this paper proposes multiple leaf code reservation (MLCR) schemes, where different numbers of orthogonal variable spreading factor (OVSF) leaf codes (i.e.,(More)
In mobile cellular systems with link adaptation (LA), different quality zones, in terms of the Signal-to-Interference Ratio (SIR), are distinguished. In this paper, the quality zone residence time distribution in mobile cellular systems with link adaptation is addressed. The cell residence time distribution has been widely studied in the literature.(More)
