Keywords: S-UMTS; AMR; TTI; spreading factor; slot format

Abstract:
Scalable Universal Mobile Telecommunications System (S-UMTS) carriers occupy bandwidth different than regular UMTS carriers and may fit in available spectrum that cannot be used by UMTS carriers today. Due to the bandwidth scaling, the data rates in S-UMTS are scaled by the bandwidth scaling factor compared to regular UMTS for the same physical layer configuration. However, some services like Circuit-Switched (CS) voice needs the same data rate in S-UMTS as in regular UMTS. The modified configuration needed in S-UMTS to maintain the data rate of such services is proposed. Additionally, both uplink and downlink voice capacity in S-UMTS are shown to scale with the bandwidth scaling factor.
