摘要： A method for operating a terminal for supporting a handover in a heterogeneous network is provided. The method includes measuring received signal strength from a target small base station, so that a Signal-to-Noise Ratio (SNR) is estimated, when the SNR of the target small base station that considers a biased value for range expansion is greater than an SNR of a serving macro base station, determining whether an SNR of the target small base station that does not consider the biased value for the range expansion is equal to or less than a threshold, and when the SNR of the target small base station that does not consider the biased value for the range expansion is equal to or less than the threshold, transmitting indication information, informing that a low SNR is expected when the terminal performs a handover to the target small base station, to the serving macro base station.

摘要： 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.
