    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: Methods of controlling a transmission power and configuring a codebook in a multi-antenna system to solve a transmission power unbalance between antennas are disclosed. The method of transmitting data in a multi-antenna system includes (A) transmitting one or more pilot signals within a first symbol region through a first antenna unit, and (B) transmitting one or more pilot signals within a second symbol region through a second antenna unit, wherein data within the first symbol region is transmitted through the second antenna unit, and data within the second symbol region is transmitted through the first antenna unit. According to the present invention, since a transmission power unbalance between antennas is solved, a transmission power can be uniformly assigned to each antenna and channel estimation can be easily performed.
