Patent ID: 8687575

Claim:
A terminal apparatus comprising: a discrete Fourier transform (DFT) section configured to perform DFTs on a plurality of symbol sequences, each symbol sequence corresponding to one of a plurality of layers; a precoder configured to multiply the plurality of DFT performed symbol sequences by a precoding matrix; and a mapper configured to map each of the plurality of precoded symbol sequences on a same set of discontinuous frequency resources, each frequency resource being located on a separate position from other frequency resources on a frequency axis, wherein the same set of discontinuous frequency resources means that a first set of discontinuous frequency resources, to which a first precoded symbol sequence is mapped, and a second set of discontinuous frequency resources, to which a second precoded symbol sequence is mapped, share at least one of a number of clusters, a cluster size, and a cluster interval in common, the cluster size being a discontinuous frequency resource bandwidth.
