| 发明名称 | Pre-coding/pre-decoding method and apparatus for data transmission in mobile communication system | ||
| 摘要 | A pre-coding/decoding method and apparatus for data transmission between a transmitting end and a receiving end is provided. The pre-coding method for data transmission through Time Division Duplexing (TDD) in a mobile communication system includes estimating downlink channel state information based on an uplink sounding signal, and pre-coding a data symbol and a reference signal based on the estimated downlink channel state information. | ||

| 主权项 | 1. A pre-coding method for data transmission through Time Division Duplexing (TDD) in a mobile communication system, the method comprising: estimating downlink channel state information based on an uplink sounding signal; and pre-coding a data symbol and a downlink sounding signal based on the estimated downlink channel state information, wherein the downlink sounding signal is used to compensate for a difference between an uplink channel value and a downlink channel value. | ||
