Abstract:
1. A transmission apparatus comprising: a coding section configured to encode first data and second data; and a mapping section configured to map the encoded first data to symbols in a first part of a domain comprising a time index and a frequency index, and the encoded second data to groups of symbols in a second part of the domain, wherein: at least a part of the encoded first data is mapped to at least a part of the symbols in the first part of the domain in an increasing order according to the frequency index; at least a part of the encoded second data is mapped to at least a part of the groups of symbols in the second part of the domain and each group of the at least a part of the groups of symbols is aligned in an increasing order according to the time index; and each symbol within each of the groups of symbols is aligned along the frequency index.
