Abstract
A wireless communication device transmits data to multiple wireless terminals at the same timing. The wireless communication device includes a complement calculation part configured to calculate the amount of complement for transmission data for each wireless terminal among multiple wireless terminals on multiple subcarriers distributed and assigned thereto, a complementation part configured to complement transmission data using the amount of complement calculated for each wireless terminal, and a transmitter configured to transmit the complemented transmission data to multiple wireless terminals via multiple subcarriers. The wireless communication device further includes a frame generator configured to generate frames (e.g. OFDMA frames) used to multiplex and transmit the complemented transmission data to multiple wireless terminals. The complement calculation part calculates the amount of complement based on the number of available subcarriers, which is determined via carrier sensing.
