PROBLEM TO BE SOLVED: To provide a control and training symbol transmission method and a device to improve transmission efficiency in a multiuser radio communication system.SOLUTION: In one embodiment, the control and training symbol transmission method for the multiuser radio communication system includes the steps of: when simultaneously transmitting data that are different from each other to respective terminals, determining whether a requested transmission rate of each data is achieved through channel estimation in each terminal; and configuring and transmitting a data frame to each terminal in a manner to be capable of separating the control and training symbols to each terminal using the combination of a time, a frequency and a code region, when it is determined, on the basis of the determination result, that the requested transmission rate of each data is not achieved. |
