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 base station in a wireless communication system, the method comprising:
- transmitting, to a mobile station through a primary frequency band, control information on one or more secondary frequency bands different from the primary frequency band;
communicating with the mobile station through the primary frequency band;
performing a synchronization procedure with the mobile station through a first secondary frequency band from among the one or more secondary frequency bands;
in response to the mobile station acquiring synchronization with the first secondary frequency band, receiving, from the mobile station through the first secondary frequency band, a readiness indication message indicating that the first secondary frequency band is prepared for a data transmission on the first secondary frequency band based on the control information;
andtransmitting, to the mobile station, a first data signal through the primary frequency band concurrently with a second data signal through the first secondary frequency band in response to receiving the readiness indication message, the first and second data signals comprising data transmissions for the mobile station.

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.
