    摘要: A method of transmitting channel quality indicator (CQI) includes obtaining CQI of each, of the plurality of sub-bands, selecting a first sub-band having the best CQI of the plurality of sub-bands, transmitting the best CQI of the first sub-band at a first transmission cycle and transmitting a difference value between the best CQI of the first sub-band and a CQI of the first sub-band at a second transmission cycle. Signalling overhead due to CQI transmission can be reduced.

    摘要: A method for efficiently transmitting and receiving feedback information is disclosed. A cluster size as a unit for computing the feedback information and a reporting period of the feedback information are not uniformly determined by a base station. Information about a downlink channel status of each user equipment is reported, the cluster size and feedback period for computing and reporting the feedback information are determined using the information about the downlink channel status of each user equipment, and the feedback information is transmitted/received, thereby improving system capability.

    摘要: A method of transmitting data in a multiple antenna system includes transmitting first data through a first pilot pattern zone in which pilots are arranged in a specific pilot pattern in a permutation zone having at least one tile comprising a plurality of orthogonal frequency division multiplexing (OFDM) symbols and a plurality of subcarriers, and transmitting second data through a second pilot pattern zone in which pilots are arranged in another pilot pattern different from the pilot pattern of the first pilot pattern zone in the permutation zone. Accordingly, a plurality of pilot patterns can be simultaneously used in one permutation zone, and thus waste of radio resources caused by the use of unnecessary pilots can be reduced by adaptively assigning pilots according to various channel environments and performances of user equipments.

    摘要: A method of transmitting a midamble for channel estimation of multiple antennas performed by a base station in a system having segregated uplink and downlink frequency bands is provided. The method includes transmitting midamble information indicating presence of the midamble within a downlink frame to a user equipment (UE), and transmitting the midamble on a single downlink subframe among at least one downlink subframe included in the downlink frame or on a common zone to the UE by using the multiple antennas. A scheduling overhead of a base station and other overheads can be reduced by decreasing the number of transmissions of a midamble on one downlink frame, and thus limited radio resources can be effectively used.
