Abstract: An equalizer-based receiver and an operating method thereof in a wireless communication system are provided. The equalizer-based receiver includes a reception multi-path detector, a controller, and an equalize receiver. The reception multi-path detector groups reception signals according to a predetermined reference to classify the reception signals into a plurality of delay clusters, and estimates a position of the plurality of delay clusters. The controller determines whether the plurality of delay clusters exist within a predetermined threshold range based on a result of the estimated position, and controls an operation mode of the equalizer-based receiver depending on a result of the determination. The equalize receiver performs one of a mode for removing an interference between the plurality of delay clusters and a mode for applying a diversity technique to a delay cluster under control of the controller.

Abstract: A method for transmitting a Channel Quality Indicator (CQI) by a CQI transmission apparatus in a communication system is provided. The method includes generating a CQI based on a CQI metric generated using a CQI_offset compensation value, and transmitting the CQI to a CQI reception apparatus, wherein the CQI_offset compensation value is generated using a CQI_offset and wherein a CQI_offset control value, and the CQI_offset is generated using Acknowledgement (Ack)/Non-Acknowledgement (Nack) information for a transmitted transport block.
