Filed: 2001-09-07
Abstract: PURPOSE: A method for controlling a signal power in a variable data rate mode is provided to control the power of a pilot signal in the variable data rate mode. CONSTITUTION: A terminal judges whether it is possible to increase or maintain a data rate according to an increase or decrease command of the data rate(S32,S35). If it is possible to increase or maintain the data rate, the terminal calculates an effective data rate(Reff(i)) in the ith frame time which is greater than an effective data rate in a previous frame time at two times(S34) or is identical to the effective data rate in the previous frame time(S35). The terminal calculates an effective data rate(Reff(i)) in the ith frame time which is less than the effective data rate in the previous frame time at 1/2 times(S36). The terminal refers to a reference pilot power level(PL(Reff(i))) corresponding to the calculated effective data rate(Reff(i)) in the ith frame time(S37). The terminal checks whether effective data rates, during a predetermined N frame delay time, are greater or same to an effective data rate in the (1-N)th frame time(S38). If the effective data rates during the predetermined N frame delay time are greater or same to the effective data rate in the (1-N)th frame time, the terminal sets the reference pilot signal power level in the ith frame time as a PL(Reff(i-N)) value(S40). If the effective data rates during the predetermined N frame delay time are less than the effective data rate in the (1-N)th frame time, the terminal compares the reference pilot signal power level(PL(Reff(i))) with a reference pilot signal power level(PL(i-1)) used in the previous frame time(S39). If the PL(i-1) is greater than the PL(Reff(i)), the terminal instantly changes a reference pilot power level used in a current frame to the PL(Reff(i))(S41). The terminal defines a traffic power level about an R-NPDCH(Reverse-New Packet Data CHannel) by the data rate, and defines a traffic level about an R-RPDCH(Reverse-Retransmission Packet Data CHannel) by an energy decrease factor(S43). The terminal transmits the ith frame according to the reference pilot signal power level and the traffic power level(S44).
