Abstract:
A cellular system comprises a mobile station and a base station. The mobile station includes a means for transmitting a pilot signal synchronized with data transmission and a means for transmitting a pilot signal not synchronized with data transmission. The base station includes a means for measuring an interference power based on the received power of the field of the pilot signal synchronized with data transmission, a means for measuring a desired wave power based on the received power of the field of the pilot signal not synchronized with data transmission, and a means for estimating the channel quality of the mobile station based on the interference power and the desired wave power.
