METHOD AND APPARATUS FOR TRANSMITTING RECEPTION CONFIRMATION IN WIRELESS SYSTEM

摘要

Provided arc a method and an apparatus for transmitting a reception confirmation in a wireless system. A terminal determines at least one downlink sub-frame for ACK/NACK feedback from each of a plurality of serving cells and determines the number of ACK/NACK bits for the plurality of serving cells. The terminal generates bundled ACK/NACK bits by arraying the ACK/NACK bits in the ascending order of the cell index of the plurality of serving cells, and transmits the bundled ACK/NACK bits.

1. A method of transmitting a reception acknowledgement in a wireless communication system, the method comprising:
determining, by a user equipment (UE), a number of acknowledgement (ACK)/negative-acknowledgement (NACK) bits for a plurality of serving cells; determining, by the UE, a number of a plurality of downlink subframes for which the UE needs to feedback ACK/NACK bits in each of the plurality of serving cells; arranging the ACK/NACK bits in an ascending order of cell indexes of the plurality of serving cells such that the ACK/NACK bits include a series of ACK/NACK bits for downlink subframes of a first cell having a lowest cell index and a series of ACK/NACK bits for downlink subframes of a second cell having a cell index next to the lowest cell index; and transmitting, by the UE, the ACK/NACK bits to a base station.
