System and method for transmitting and receiving a signal using multiple frequency bands in a wireless communication system
First Claim
1. A method of managing frequency bands by a mobile station in a wireless communication system, the method comprising:
- receiving a first message including information regarding a first secondary frequency band from a base station using a primary frequency band;
transmitting a readiness indication message, the readiness indication message comprising a message configured to inform the base station regarding readiness for use of the first secondary frequency band in the mobile station;
if the readiness indication message is not received by the base station within a time period, receiving a second message including information regarding a second secondary frequency band from the base station; and
in response to the second message including information regarding a second secondary frequency band, which is different from the first secondary frequency band, received from the base station, performing communication with the base station using the primary frequency band and the second secondary frequency band according to the information regarding the second secondary frequency band.

Abstract
Disclosed is a system and a method of signal transmission/reception by a mobile station in a wireless communication system. The method includes: transmitting a first sub-band preparation indicator, which indicates that the mobile station has been prepared for transmission/reception of a signal through a first sub-band, to a base station through a primary band; transmitting a first sub-band failure indicator to the base station through the primary band upon detecting failure in transmitting the first sub-band preparation indicator; receiving sub-band information on a second sub-band, which is different from the first sub-band, from the BS through the primary band; and acquiring synchronization with the second sub-band, so as to enable transmission/reception of a signal through the second sub-band based on the sub-band information.
