Abstract
A wireless communications device that transmits a multiplexed signal of a plurality of data sets of different sizes to a communications terminal includes an empty resource block detection section, which detects empty resource blocks of the data sets each of which does not use any of a predetermined number of resource blocks, from among the plurality of data sets whereto the predetermined number of resource blocks are allocated in the time direction and the frequency direction; and a data redistribution section that redistributes a part of data that is distributed in resource blocks, with respect to the data sets whereto resource including empty resource blocks are allocated, in the vicinity of pilot symbols that are disposed within the empty resource blocks. It is possible to effectively utilize the function of all the pilot symbols and improve error rate characteristics.
