METHOD AND APPARATUS FOR TRANSMITTING UPLINK SIGNALS IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for transmitting, by a UE, acknowledgement/negative acknowledgement (ACK/NACK) information in a carrier aggregation based wireless communication system, comprising:
- aggregating a first time division duplex (TDD) cell having a first uplink downlink (UD) configuration and a second TDD cell having the first UD configuration;
transmitting ACK/NACK information corresponding to the first TDD cell through a UL subframe (SF) on the first TDD cell; and
transmitting ACK/NACK information corresponding to the second TDD cell through a UL SF on the second TDD cell,wherein UL SF timing on the first TDD cell is provided as a UL SF set according to the first UD configuration, and UL SF timing on the second TDD cell is provided based on a subset belonging to a UL SF set according to the first UD configuration,wherein SF configurations according to UD configurations are as follows,

Abstract
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus for a terminal transmitting ACK/NACK information in a carrier aggregation-based wireless communication system, comprising the steps of: aggregating a first TDD cell having a first UD configuration and a second TDD cell having the first UD configuration; transmitting ACK/NACK information corresponding to the first TDD cell through a UL SF on the first TDD cell; and transmitting ACK/NACK information corresponding to the second TDD cell through a UL SF on the second TDD cell, wherein the timing of the UL SF on the first TDD cell is provided as a UL SF set according to the first UD configuration, and the timing of the UL SF on the second TDD cell is provided based on a subset under the UL SF set according to the first UD configuration.
