MOBILE STATION, BASE STATION, AND METHOD

摘要

A disclosed mobile station is designed to send or receive at least a control channel using a given frequency in a first operating mode and to tune to a frequency different from the given frequency and perform a neighboring cell search in a second operating mode. The mobile station includes a measuring unit configured to obtain a measurement of radio channel quality at a measurement interval; and a determining unit configured to compare the measurement and a threshold and to select one of the first operating mode and the second operating mode based on the result of comparison. The mobile station allows a base station to recognize the operating mode of the mobile station either by preventing reporting of the measurement lower than the threshold to the base station or by transmitting a signal indicating the selected operating mode to the base station.
