In user terminalof the present invention, connection-cell-selection controlling sectionmeasures reception quality of signals respectively transmitted from cells and received by antenna section, corrects the reception quality of each of the cells based on a positional relationship between each of the cells and user terminaland based on a moving direction of user terminal, and determines a connection cell for user terminal(base station in communication with user terminal) based on the corrected reception quality. This configuration lowers a cell switching frequency, while preventing degradation of throughput and the like in a future radio communication system (multilayer cellular radio network).
