Patent ID: 8726117

Claim:
A wireless transmission apparatus that transmits data coded by error correction coding in, respectively, a first layer included in a physical layer and a second layer higher than the first layer, the wireless transmission apparatus comprising: a second layer coding section that codes a transmission data series by a coding unit in the second layer and divides coded data into a plurality of data units; an identification information addition section that adds identification information for identifying the coding unit in the second layer to each of the plurality of data units; and a first layer processing section that includes error correction coding for coding each of the plurality of data units, to which the identification information is added, by a coding unit in the first layer, wherein: the identification information added to each of the plurality of data units identifies that each of the plurality of data units is comprised of a same coding unit in the second layer, wherein the wireless transmission apparatus comprises an adjustment section that adjusts a first layer transmission parameters used by the first layer processing section on the basis of feedback information from a wireless reception apparatus that receives the transmission data.
