Abstract:
1. A mapping method of mapping subcarriers in a base station, comprising: identifying a condition of a communication environment between the base station and a single mobile station on the basis of channel quality information transmitted from the mobile station within a plurality of resource blocks assigned to the mobile station composed of a predetermined number of subcarriers in a predetermined communication band; judging whether or not the condition of the communication environment is good within the resource blocks assigned to the mobile station in comparison with a predetermined criterion to determine a good resource block, if the good resource block is present within the plurality of the resource blocks assigned to the mobile station; preferentially mapping a specific control signal, of a plurality of control signals used for control of communication, selectively to a specified subcarrier within the good resource block, if the good resource block is present within the plurality of the resource blocks assigned to the mobile station, wherein an importance of the specific control signal is different from an importance of other control signals of the plurality of control signals; and mapping the plurality of control signals onto subcarriers within the predetermined communication band in a predetermined order of frequencies, if the good resource block is not present within the plurality of the resource blocks assigned for the mobile station.
