US 2017/0289988 A1 · SYMBOL MAPPING METHOD FOR REPETITION CHANNEL CODING

Abstract

A symbol mapping method for repetition coding is disclosed. The symbolmapping method comprises performing repetition coding on codeword to output repeated codeword symbols, and mapping the repeated codeword symbols with subcarriers located in different localized resource blocks. According to the embodiments of the present invention, it is possible to obtain maximum reliability in a receiving side by mapping codeword bits with subcarriers to reduce the number of bits having low reliability when a transmitting side usesrepetition coding. Also, it is possible to improve decoding throughput and obtain channel diversity.

Claims6

Dependent claims

A method for transmitting a signal at a base station in a mobile communication system, the method comprising:

performing repetition coding on an information bit to generate a plurality of information bits;
obtaining a plurality of modulation symbols from the plurality of information bits;
mapping the plurality of modulation symbols to one or more orthogonal frequency division multiplexing (OFDM) symbols;
and
transmitting the plurality of mapped modulation symbols,
wherein at least two of the plurality of modulation symbols are mapped separately from each other in the frequency domain to a same OFDM symbol.
