1. A base station apparatus comprising:

  • a scheduler configured to determine a resource allocation to map each of a plurality of precoded symbol sequences to a plurality of frequency resources, each of the plurality of frequency resources being located on a separate position from other frequency resources on a frequency axis, wherein the plurality of precoded symbol sequences are generated at a terminal apparatus by multiplying a plurality of symbol sequences by a precoding matrix, each symbol sequence corresponding to one of a plurality of layers, wherein a first plurality of frequency resources to which a first precoded symbol sequence is mapped, and a second plurality of frequency resources to which a second precoded symbol sequence is mapped share;

    a number of clusters used to map each precoded symbol sequence;

    a cluster size; and

    a frequency position of each cluster, the cluster size being a discontinuous frequency resource bandwidth;

    a transmitter configured to notify the terminal apparatus of information indicating the determined resource allocation;

    a receiver configured to receive a signal including the plurality of precoded symbol sequences which are mapped to the plurality of frequency resources; and

    a combiner configured to combine the plurality of frequency resources to generate symbol sequences.
