Abstract:
1. A wireless communication device for performing a spatial multiplexing transmission using a plurality of streams, the wireless communication device comprising: a signal generator that allocates a pilot signal to a part of resource allocation areas to which no data addressed to a terminal device is allocated with pilot allocation patterns different between a continuous resource allocation method where a group of subcarriers that are contiguous is allocated and a distributed resource allocation method where a group of subcarriers that are distributed along a frequency axis is allocated, the resource allocation areas being within a resource unit that includes a plurality of resource elements with multiple OFDM symbols and multiple subcarriers, wherein the pilot allocation pattern defines which resource element among the plurality of resource elements is used to allocate the pilot signal; and a transmitter having a plurality of antenna ports that transmit the allocated pilot signal.
