Reconfigurations of downlink dedicated channels are often necessary during call setup to eliminate code blocking encountered in 3G WCDMA systems. These reconfigurations increase not only the signaling overhead, but also the setup delay of the incoming call and may yield prohibitive delays if performed inefficiently. In this paper, we introduce a reconfiguration scheme which manages to minimize this additional setup delay with a tolerable increase in signaling overhead.
