A TFC selection apparatus includes: a SIR calculation unit calculating SIR by using a CPICH symbol of receive data; a conversion unit obtaining STFC(m) which contains m pieces of TFC corresponding to the calculated SIR; a total transmit power calculation unit selecting TFC corresponding to the obtained STFC(m) from a TFCS which is a set of TFCs sequenced in proportion to a magnitude of total transmit power, and calculating total transmit power of TFC included in the TFCS in order indicated by a search direction signal, beginning with the selected TFC as a starting point; and a TFC selection unit generating the search direction signal based on the calculated total transmit power of the TFC as the starting point, and selecting an optimum TFC to be applied to transmit data from the TFCS, wherein the TFC selection unit selects TFC as the optimum TFC corresponding to total transmit power which indicates less than or equal to as well as approximate to a maximum value allowed for the transmit data.
