Abstract: Methods and apparatus are provided for transmitting and receiving data in a wireless communication system. Resource allocation information is received and hopping-related information is identified. A resource for transmitting data is determined based on the resource allocation information and hopping-related information, and data is transmitted on the determined resource. A sub-band is determined from a plurality of sub-bands based on the first hopping parameter and a resource in the determined sub-band is determined based on the second hopping parameter.

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: Methods and apparatuses are provided for wireless communication. A scheduling message is received that includes first information on at least one resource allocated for uplink transmission and second information. Data and a pilot are transmitted via the allocated at least one resource for uplink transmission. An ACK/NACK resource is identified based on a lowest index among at least one index of the allocated at least one resource for uplink transmission and the second information. An ACK/NACK signal is received in response to the transmitted data using the identified ACK/NACK resource.
