A RADIO TERMINAL, RADIO BASE STATION, CHANNEL SIGNAL FORMING METHOD AND CHANNEL SIGNAL RECEIVING METHOD WHEREIN WHEN AN UPSTREAM UNIT BAND AND A PLURALITY OF DOWNSTREAM UNIT BANDS ASSOCIATED THEREWITH ARE USED TO PERFORM COMMUNICATIONS, THE QUALITY OF DOWNSTREAM ASSIGNMENT CONTROL INFORMATION CAN BE PREVENTED FROM BEING DEGRADED. IN A BASE STATION (100), THE PDCCH SIGNALS INCLUDING UPSTREAM ASSIGNMENT CONTROL INFORMATION ARE LIMITED TO ONES THAT ARE PLACED IN SOME OF THE DOWNSTREAM UNIT BANDS. THIS CAN REDUCE THE PROBABILITY OF PERFORMANCE OF ZERO PADDING TO DOWNSTREAM ASSIGNMENT CONTROL INFORMATION HAVING GREATER IMPORTANCE. ALSO IN THE BASE STATION (100), THE PDCCH SIGNALS OF THE DOWNSTREAM UNIT BANDS OTHER THAN THE BASIC UNIT BAND INCLUDE ONLY DOWNSTREAM RESOURCE ASSIGNMENT INFORMATION. FOR THIS REASON, IN THE INDIVIDUAL REGIONS OF THE DOWNSTREAM UNIT BANDS OTHER THAN THE BASIC UNIT BAND, THE BANDWIDTH OF THE DOWNSTREAM UNIT BANDS IS ALWAYS USED AS A REFERENCE OF SIZE ADJUSTMENT AND HENCE REQUIRES NO INFORMATION SIZE ADJUSTMENT. AS A RESULT, THERE IS NO NEED OF PERFORMING ZERO PADDING TO THE DOWNSTREAM ASSIGNMENT CONTROL INFORMATION, SO THAT THE QUALITY OF DOWNSTREAM ASSIGNMENT CONTROL INFORMATION CAN BE PREVENTED FROM BEING DEGRADED.
