Method for transmitting response information in a wireless communication system, and apparatus for same

摘要

The present invention relates to a method for transmitting response information on downlink data through multiple information blocks to be bundled in a wireless system in a time division duplex (TDD) mode. The method for transmitting response information according to the present invention comprises the following steps: coding response information on the downlink data; scrambling the coded response information; and transmitting the scrambled response information to a base station, wherein, if a portion of the bits of the coded response information are information bits that indicate ACK/NACK on the downlink data, the scrambling step involves scrambling the coded response information using a specific scrambling sequence, and the specific scrambling sequence includes information on the number of information blocks to be bundled.

1. A method for transmitting response information for a plurality of bundled information blocks in a wireless system of a time division duplex (TDD) mode, the method comprising:
coding the response information for the plurality of bundled information blocks; scrambling the coded response information; and transmitting the scrambled response information to a base station, wherein, in the scrambling, if some bits of the coded response information are information bits indicating acknowledgement (ACK)/negative acknowledgement (NACK) on the downlink data, the coded response information b(i) is scrambled using a specific scrambling sequence according to the following equation:
{tilde over (b)}(i)=(b(i)+c(i))mod2, wherein b(i) denotes the coded response information, {tilde over (b)}(i) denotes the scrambled response information, and c(i) denotes the specific scrambling sequence, and wherein the specific scrambling sequence has an initial value determined by the number of bundled information blocks.
