Method for performing channel interleaving in a multi-antenna wireless communication system, and apparatus for same

摘要

The present application relates to a method in which a terminal performs channel interleaving in a multi-antenna wireless communication system. More particularly, the method comprises the following steps: constructing both channel quality indicator (CQI) information and coded data information into preset bit-wide vectors to generate a first interleaver input vector sequence; repeating both rank indicator (RI) information and acknowledgement/negative acknowledgement (ACK/NACK) information per the number (NL) of transmission layers to generate a second interleaver input vector sequence of preset bit-wide vectors and a third interleaver input vector sequence of preset bit-wide vectors; mapping the first interleaver input vector sequence, the second interleaver input vector sequence, and the third interleaver input vector sequence to an interleaver matrix, respectively; and reading the interleaver matrix by a column basis to generate an output vector sequence. The preset bit-wide is defined by the product of a modulation order (Qpm) and the number (NL) of transmission layers.

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 NL of transmission layers; generating a third interleaver input vector sequence of the predetermined bit unit by repeating coded acknowledgement (ACK)/negative ACK (HACK) information by the number NL of transmission layers; 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 Qpm and the number NL, of transmission layers.
