    摘要: A method for performing a Hybrid Automatic Repeat reQuest (HARQ) operation in a wireless mobile communication system that uses Frequency Division Duplex (FDD) or Time Division Duplex (TDD) frames each having a plurality of subframes for communication are provided, in which an HARQ timing including a transmission time of a data burst and a transmission time of an HARQ feedback, for DL HARQ is determined according to data burst assignment information transmitted in a # l DownLink (DL) subframe of a #i frame, and an HARQ operation is performed according to the determined HARQ timing. At least one frame index and at least one subframe index that represent the HARQ timing are determined by using l and i.

    摘要: An apparatus and method for switching between an AMC mode and a diversity mode adaptively according to a channel environment in a broadband wireless communication system are provided. According to the present invention, a transmitter (a base station) determines a transmission mode according to frequency-domain and time-domain channel measurement information received from a receiver (a mobile station). If the transmission mode is the AMC mode, the transmitter selects a coding and modulation scheme according to a frequency-domain CQI received from the receiver. If the transmission mode is a diversity mode, the transmitter selects a predetermined coding and modulation scheme.

    摘要: An apparatus and method for transmitting a reference signal in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system in which a total frequency band is divided into a plurality of subcarrier bands. A time division multiplexer performs time division multiplexing such that the reference signal is transmitted for a first duration in a predetermined number of subcarrier bands from among the plurality of the subcarrier bands, and a signal other than the reference signal is transmitted for a second duration other than the first duration. A transmitter transmits the time-division multiplexed subcarrier band signals.
