Abstract:
1. A wireless transmitting apparatus that has a plurality of antennas and that performs wireless transmission in Multiple Input Multiple Output (MIMO) or non-MIMO using an Orthogonal Frequency Division Multiplexing (OFDM) signal, where a block is comprised of a plurality of sub-blocks, the wireless transmitting apparatus comprising: the plurality of antennas configured to transmit a pilot signal, shared control information, and user data; and a mapping section that is configured to map the pilot signal, the shared control information, and the user data, on the sub-block by sub-block basis, wherein the mapping section is configured to map the user data in a block so that the user data mapped on the sub-blocks is transmitted in either MIMO or non-MIMO, wherein the mapping section is configured to map the shared control information included in a same block as the user data so that the shared control information mapped on the sub-blocks is transmitted in non-MIMO, and wherein the mapping section is configured to map the shared control information and the pilot signal so that allocation of the pilot signal for performing propagation path estimation to decode the shared control information mapped on predetermined allocation of the sub-block are not changed regardless of whether user data included in the same block as said shared control information is transmitted in MIMO or non-MIMO.
