System and method for transmitting and receiving a signal using multiple frequency bands in a wireless communication system
First Claim
1. A method of signal transmission/reception by a mobile station in a wireless communication system, the method comprising the steps of:
- 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.
