Abstract:
A method for generating a transmission signal to transmit an orthogonal frequency division multiplexing signal, from one antenna or from a plurality of antennas, to a plurality of terminals. Transmission data for the plurality of terminals is assigned to a plurality of carrier groups, each carrier group including a plurality of carriers. For each of the plurality of carrier groups, one of a first frame configuration is selected, wherein one modulated signal is transmitted, and a second frame configuration is selected wherein a plurality of modulated signals are transmitted by using the plurality of antennas. A transmission signal is generated using the selected frame configuration, for transmitting the transmission data assigned to the plurality of carrier groups during a certain period.
