	According to one of the methods of dynamic power control (Code Hopping) used in W-CDMA technology, the Rate Information (RI) field in the uplink control channel in W-CDMA frame can be used to notify the base station about the variable bit rates (VBR) it wants to send, then the base station assigns a new spreading factor for each data rate and hence the optimal power calculation is done according to the spreading factor as follows.<br> Spreading factor(Gi) is defined as the ratio of bandwidth of the system to the data rate of the radio frame.

 ===QoS Management Algorithms===
 Quality of Service can be managed according to the varying type of traffic i.e. data, voice, video in the following four ways.
