FIELD: wireless communication equipment.
SUBSTANCE: duration of the symbol includes the duration of the useful symbol and the duration of the associated cyclic prefix. Subcarrier spacing variables and the symbol duration are determined by parameters indicating the spacing between the subcarriers, the length of the useful symbol, and the duration of the cyclic prefix. Method according to the embodiment of the invention, which is performed by the network or network controller, includes creating a plurality of types of the multiple access unit, MAB unit, defining various combinations of subcarrier spacing and symbol duration for signal waveforms.
EFFECT: ensuring the possibility of the use of different OFDM configurations for different channel conditions by providing a dynamic selection of subcarrier space and symbol duration.
