摘要

PROBLEM TO BE SOLVED: To shorten time required for selecting a frequency unit used for transmitting data from a terminal to a base station. SOLUTION: The terminal performs communication in a frequency unit fluctuation transmission mode for transmitting a prescribed uplink signal to the base station 100 by sequentially using a plurality of kinds of frequency units and a frequency unit fixed transmission mode for communicating with the base station 100 by using a specific frequency unit among the plurality of kinds of frequency units, selected based on base station side signal quality which is signal quality of the prescribed uplink signal received by the base station 100.
