The overhead of notifications of other-user modulation information contained in individual control information in a multiuser-MIMO mode is reduced. A wireless communication device according to the invention includes: a pilot sequence allocation section which allocates pilot sequence numbers that are used in spatial multiplexing streams based on modulation information of the spatial multiplexing streams to a plurality of counterparty wireless communication devices that perform multiuser-MIMO transmission; a first modulation information generation section which generates modulation information and pilot sequence allocation number information that are related to a first spatial multiplexing stream addressed to a first counterparty wireless communication device of the plurality of counterparty wireless communication devices; and a second modulation information generation section which generates modulation information related to spatial multiplexing streams addressed to other counterparty wireless communication devices excluding the first counterparty wireless communication device, in order of pilot sequence numbers allocated to the spatial multiplexing streams addressed to the other counterparty wireless communication devices excluding the first counterparty wireless communication device. The wireless communication device notifies the first counterparty wireless communication device of the modulation information and pilot sequence allocation number information which are generated by the first modulation information generation section and the second modulation information generation section.
