摘要

Disclosed is a method for obtaining a GPS signal by a user terminal operating in a time division duplex method, the user terminal receiving the GPS signal and a base station signal, the method includes setting a maximum window reception interval for attempting a GPS signal acquisition; setting within a frame an interval for attempting the GPS signal acquisition and attempting the GPS signal acquisition; exponentially increasing the time period for attempting the GPS signal acquisition and reattempting a GPS signal acquisition, when the GPS signal is not obtained in the set interval for the GPS signal acquisition; and ending the GPS signal acquisition attempts when the interval for the GPS signal acquisition is greater than or equal to the maximum window reception interval.
