Mobile station, radio base station, and mobile communication method

A mobile station comprising:

• a reception quality measurement unit configured to measure a reception quality of a pilot signal of each of a plurality of cells, when a radio link is established with the plurality of cells;
• a channel quality information transmission unit configured to transmit, to a first cell having the best reception quality among the plurality of cells, channel quality information corresponding to the reception quality;
• and
• a control signal transmission unit configured to transmit, to cell other than the first cell among the plurality of cells, a control signal requesting not to transmit a data signal by using the same resource as the first cell.

A mobile communication method, comprising the steps of:

• measuring, at a mobile station, a reception quality of a pilot signal of each of a plurality of cells, when a radio link is established with the plurality of cells;
• transmitting, from the mobile station to a first cell having the best reception quality among the plurality of cells, channel quality information corresponding to the reception quality;
• transmitting, from the mobile station to a cell other than the first cell among the plurality of cells, a control signal requesting not to transmit a data signal by using the same resource as the first cell;
• and
• performing scheduling not to transmit the data signal by using the same resource as the first cell in the cell other than the first cell, when the control signal is received from the mobile station.
