Abstract:
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: 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.
