Abstract
An interleaving method to which time-first-mapping is applied for a plurality of channel-coded and rate-matched code blocks in a mobile communication system is provided. The interleaving method includes determining sizes of a horizontal area and a vertical area of an interleaver, generating modulation groups with adjacent coded bits in a vertical direction according to a modulation scheme, sequentially writing the modulation groups in the horizontal area on a row-by-row basis, and sequentially reading the coded bits written in the interleaver in the vertical area on a column-by-column basis.
Claims23
An interleaving method to which time-first-mapping is applied for at least one channel-coded and rate-matched code blocks in a mobile communication system, the method comprising:
- determining sizes of a horizontal area and a vertical area of an interleaver;
- writing coded bits of modulation groups in the horizontal area of the interleaver on a row-by-row basis, the modulation groups comprising a number of coded bits and the number of coded bits being determined based on a modulation scheme;
- and
- reading the coded bits written in the interleaver from the vertical area of the interleaver on a column-by-column basis.
A deinterleaving method to which time-first-mapping is applied for at least one channel-coded and rate-matched code blocks in a mobile communication system, the method comprising:
- determining sizes of a horizontal area and a vertical area of a deinterleaver;
- writing inputted coded bits in the vertical area of the deinterleaver on a column-by-column basis;
- and
- reading coded bits of modulation groups from the horizontal area of the deinterleaver on a row-by-row basis, the modulation groups comprising a number of coded bits, and the number of coded bits being determined based on a modulation scheme.
An interleaving apparatus to which time-first-mapping is applied for at least one channel-coded and rate-matched code blocks in a mobile communication system, the apparatus comprising:
- an interleaver;
- a controller for determining sizes of a horizontal area and a vertical area of the interleaver;
- a writer for writing coded bits of modulation groups in the horizontal area of the interleaver on a row-by-row basis, the modulation groups comprising a number of coded bits and the number of coded bits being determined based on a modulation scheme;
- and
- a reader for reading the coded bits from the vertical area of the interleaver on a column-by-column basis.
A deinterleaving apparatus to which time-first-mapping is applied for a plurality of channel-coded and rate-matched code blocks considering in a mobile communication system, the apparatus comprising:
- a deinterleaver;
- a controller for determining sizes of a horizontal area and a vertical area of the deinterleaver;
- a writer for writing inputted coded bits in the vertical area of the deinterleaver on a column-by-column basis;
- and
- a reader for reading coded bits of modulation groups from the horizontal area of the deinterleaver on a row-by-row basis, the modulation groups comprising a number of coded bits and the number of coded bits being determined based on a modulation scheme.
