Abstract
The receive power of uplink signals in a CDMA mobile communication system is measured by prohibiting a mobile station from transmitting an uplink signal including a frame over a first channel during a predetermined transmission prohibition period, and measuring a receive power of uplink signals at a base station transmitted from each of the mobile stations located in a cell during the prohibition period. Another method of measuring the receive power includes measuring a first receive power of uplink signals at a base station from each mobile station located in a cell, and measuring each second receive power of uplink signal including a frame only over a first channel transmitted from each mobile station, and then calculating a total receive power of uplink signals excluding frames over the first channel by subtracting respective second receive powers from the first receive power.
