摘要： A method of transmitting control information includes dividing frequency bandwidth into ranges to which the same PMI (precoding matrix index) is applied, obtaining multiple antenna information by the range to which the same PMI is applied and transmitting the multiple antenna information. Since multiple antenna information is transmitted by the unit of a range to which the same PMI is applied, radio resources allocated for transmitting the multiple antenna information may be reduced, thereby enhancing data transmission efficiency.

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.

摘要： A data transmission method for multiple users having multiple receive antennas is provided. The method includes selecting a receive antenna among the multiple receive antennas for each user, performing DPC (Dirty Paper Coding) from the multiple transmit antennas to the receive antenna and transmitting a transmission signal on which the DPC is performed. Since DPC is implemented through a receive antenna selected among multiple receive antennas, complexity is not much increased although the DPC is applied to a MIMO system.

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. Moreover, a power amplifier having a uniform amplification range can be used and designed.
