Abstract
In a communication system for respectively transmitting pilot signals from a plurality of base stations to a mobile station via a first channel and also for transmitting data from one base station to a mobile station via a second channel, the mobile station corrects total receive power at the time of handover by subtracting power of the data signal received via the second channel from the total receive power of the signals received from a base station in communication (serving cells) via the second channel, then corrects the total noise power based on the total receive power after the correction, and measures the communication environment between the base station and the mobile station using the power of the pilot signal received from the base station in-communication and the corrected total noise power.
