    摘要: A method of transmitting channel information in a multiple antenna system includes receiving the channel information comprising rank information, and transmitting a confirm message through a downlink control channel as a confirmation for the channel information, wherein the confirm message comprises overriding rank information which overrides the received rank information in an open loop scheme and also comprises information indicating whether the received channel information is used without alteration in a closed loop scheme. A rank indicator (RI) and a precoding matrix indicator (PMI) can be carried on a dedicated control channel (DCCH) and be specified through a physical downlink control channel (PDCCH).

    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.

    摘要: A method for detecting signals based on despreading and a signal transmitting method for the same are provided. Signals are spread according to the size of at least one spreading band, which is determined in consideration of a correlation degree of a frequency band in a communication system. A reception side which receives the signals detects the signals after de-spreading with respect to signals which are spread in a frequency band having a correlation degree equal to or greater than a predetermined level as a spreading band, among the reception signals. Thus, the dimension of the detected signals can be decreased.
