Abstract:
A method of controlling transmitting power of a base station in a CDMA mobile communication system, comprising the steps of:calculating desired transmitting power Pa(i) of transmitting power control object channel i (i=1,2, . . . ,n), which is one channel selected for transmitting power control from a plurality of communication channels; calculating total base station transmitting power Ptotal by adding said desired transmitting power Pa(i) and transmitting powers Ptx(j) that are currently set to communication channels j (j=1,2, . . . ,n, jâ‰ i); and setting as the new transmitting power of said transmitting power control object channel i a value obtained by reducing said desired transmitting power Pa(i) using a power reduction rate Dt and setting as the new transmitting powers of said communication channels j values obtained by reducing each transmitting power Ptx(j) currently set to said communication channels j using said power reduction rate Dt when said total base station transmitting power Ptotal is greater than a predetermined maximum total transmitting power Pmax.
