Abstract:
1. An adaptive data multiplexing transmission method in a base station for an orthogonal frequency division multiple access (OFDMA) system in which a terminal performs packet communication in coverage of a base station, and the base station transmits packet data to the terminal, the method comprising: collecting information necessary for scheduling; performing scheduling using the collected information; comparing code rate of data to be transmitted at least one terminal determined according to the scheduling result with a threshold; selecting a proper multiplexing scheme according to the comparison result; wherein the multiplexing scheme comprises a selected unitary precoded orthogonal frequency division multiplexing (OFDM), if the code rate of the data is lower than the threshold, and an OFDM, if the code rate of the data is higher than the threshold; and transmitting packet data using the selected multiplexing scheme.
