Patent ID: 7778197

Claim:
A mobile communications terminal for supporting a space-time Hybrid Automatic Repeat reQuest (HARQ) scheme, comprising: an encoder configured to encode data based upon at least one preset puncturing table; a mapper/modulator configured to map the encoded data to a physical channel and modulate the mapped data; a second interleaver configured to interleave the modulated data; a space-time block encoder configured to encode the interleaved modulated data for multiple input/multiple output (MIMO) transmitting; and at least two antennas configured to MIMO transmit the encoded interleaved data via the HARQ scheme, wherein the encoder includes: a first encoder configured to encode the data and generate first-encoded data; a first puncturer configured to puncture the first-encoded data based upon a first preset puncturing table and generating first-punctured data; a first interleaver configured to interleave the first-punctured data and generate first-interleaved data; a second encoder configured to encode the first-interleaved date and generate second-encoded data; and a second puncturer configured to puncture the second-encoded data based upon a second preset puncturing table, and wherein the second preset puncturing table comprises one of two sub-blocks, each having p bits and specifying puncturing patterns for two parity bits, with p denoting a puncturing period, and two sub-blocks arranged to exclude puncturing at a same position within the two sub-blocks.
