Abstract
Disclosed is an apparatus and method for transmitting/receiving a control message in a wireless communication system that is designed to reduce overhead associated with transmission/reception of the control message. To this end, a transmission apparatus generates a control message, generates a compressed control message by compressing the generated control message, based on a control message that has been lastly received by a reception apparatus from among previously transmitted control messages, selects one of the generated control message and the generated compressed control message according to whether or not the control message lastly received by the reception apparatus exists, and transmits the selected one of the generated control message and the generated compressed control message to the reception apparatus. Therefore, it is possible to reduce resources used for control message transmission, and thus increase the use efficiency of the resources.
