Abstract: An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.

Abstract: The present invention is a method for controlling re-direction between heterogeneous mobile communication systems, comprising a step in which a terminal, a connection request of which is rejected from a first communication system (UTRAN), receives, from a second communication system to which the terminal intends to connect, information indicating that the second communication system does not support the terminal; a step of setting information for preventing re-direction to the second communication system; and a step of transmitting, to the first communication system, a request for connection to the first communication system, which includes the information.
