Abstract:
1. A method of performing channel interleaving at a user equipment (UE) in a multi-antenna wireless communication system, the method comprising: generating a first interleaver input vector sequence by configuring each of channel quality indicator (CQI) information and coded data as vectors of a predetermined bit unit; generating a second interleaver input vector sequence of the predetermined bit unit by repeating coded rank indicator (RI) information by the number N generating a third interleaver input vector sequence of the predetermined bit unit by repeating coded acknowledgement (ACK)/negative ACK (HACK) information by the number N mapping the first interleaver input vector sequence, the second interleaver input vector sequence and the third interleaver input vector sequence to an interleaver matrix; and generating an output bit sequence by reading the interleaver matrix column by column, wherein the predetermined bit unit is defined by a product of a modulation order Q
