METHOD AND APPARATUS FOR SWITCHING A FREQUENCY ASSIGNMENT IN A WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2011/090310

A2

The present invention relates to a method and apparatus for switching a frequency assignment (FA) in a wireless communication system. According to the present invention, a base station communicates, upon detection of the mobile terminal being moved, with a mobile terminal using a first FA via a first FA-transceiving unit from among a plurality of FA-transceiving units which process signals transceived via each of the plurality of FAs, and selects, upon detection of a change in a wireless environment caused by the movement, a second FA from among the plurality of FAs to be switched in accordance with the changed wireless environment, operates a second FA-transceiving unit which processes signals transceived via the second FA, transmits, to the mobile terminal, a scanning-instructing message which instructs the reference signal transmitted via the second FA to be scanned, and switches the first FA to the second FA in accordance with the result of the scanning received from the mobile terminal in response to the scanning-instructing message.
