Disclosed is a wireless communication device whereby the overhead of reporting user modulation information contained in individual control information when in multi-user MIMO mode can be reduced. The wireless communication device includes: a pilot sequence allocation section which allocates pilot sequence numbers employed in spatially multiplexed streams destined for a plurality of remote wireless communication devices which perform multi-user MIMO transmission in accordance with the modulation information of the spatially multiplexed streams; a first modulation information generating section which generates pilot sequence allocation number information and modulation information relating to a first spatially multiplexed stream destined for a first remote wireless communication device from among the plurality of remote wireless communication devices; and a second modulation information generating section which generates, in the order of the pilot sequence numbers allocated to spatially multiplexed streams destined for remote wireless communication devices other than the first remote wireless communication device, modulation information relating to spatially multiplexed streams destined for wireless communication devices other than the first remote wireless communication device. The pilot sequence allocation number information and the modulation information generated by the first modulation information generating section and second modulation information generating section are reported to the first remote wireless communication device. |
