/ PRE-CODING/PRE-DECODING METHOD AND APPARATUS FOR DATA TRANSMISSION IN MOBILE COMMUNICATION SYSTEM

摘要

the present invention is the data relates to a transfer technique, especially relates to a pre-coding / pre-decoding method and device for data transmission between the transmitter and the receiver, Time Division Duplexing TDD (according to the invention : pre-coding method for a mobile communication system for transmitting data over a TDD) is, based on the channel state information of the process based on the UL sounding signal to estimate the channel state information of a downlink, and the estimated downlink in the data symbol and a DL sounding signal comprises a pre-coding process.
