<p>PROBLEM TO BE SOLVED: To shorten time for measuring reception quality while suppressing the control delay of closed loop transmission power control to a minimum by appropriately determining the arrangement of pilot data and data for transmission power control and appropriately arranging the slot position relation of up and down lines. SOLUTION: Both the up and down lines are appropriately provided with up and down slot offset by separately arranging the pilot data and the data for transmission power control inside slots. Namely, at a base station and a mobile station, the arrangement of data inside the slot is determined while considering delay. For example, pilot data 401 and data 402 for transmission power control are separated and between them, data 403 are sandwiched. In this case, at the mobile station, SIR (the power ratio of desired wave signal to interference wave signal) is measured while using the received pilot data 404 and the result is contained in the transmission power control data 405. Further, the slot is shifted just for Tshift .</p> |
