FIELD: radio engineering, communication.SUBSTANCE: method for transmission by a base station includes transmitting first control information, indicating whether to allocate a plurality of subcarriers lying continuously on a frequency axis or allocate a plurality of subcarriers lying discretely with a fixed interval on a frequency axis; transmitting data using said plurality of subcarriers; transmitting second control information, indicating a plurality of subcarriers lying continuously on a frequency axis when the base station transmits first control information, indicating allocation of a plurality of subcarriers lying continuously on a frequency axis.EFFECT: enabling error-free data demodulation even when quality deterioration due to freezing fluctuation continues for a long time, owing to the frequency diversity effect.6 cl, 22 dwg |
