    Abstract: In an apparatus for controlling reply signal transmission in a reply signal transmitter that generates and transmits a reply signal according to an error check in packet data received through a radio channel in a mobile communication system, an error detection part generates a reply signal corresponding to the error check from the packet data received through the radio channel. A spreading part spreads the reply signal to output the spread reply signal. A transmission power control part carries out a power control operation for the spread reply signal with a power value that differs according to a packet data transmission rate of a packet data channel. A transmission part transmits the reply signal outputted by the transmission power control part through a radio channel.

  • Publication number: 20070098093
    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.
