Title:
METHOD AND APPARATUS FOR TRANSMITTING ACK/NACK INFORMATION
Document Type and Number:
WIPO Patent Application WO/2012/165795
Kind Code:
A3
Abstract:
The present invention is provided a method for transmitting ACK/NACK information. The method is applicable for a situation that uplink-downlink configurations of multiple Component Carriers (CCs) of a Carrier Aggregation (CA) are different. The method include: transmitting, by a NodeB, a UL grant to a UE, the UL grant includes a UL Downlink Assignment Index (DAI); receiving, by the UE, the UL grant and obtaining the UL DAI in the UL grant; and transmitting, by the UE, ACK/NACK information on a Physical Uplink Shared Channel (PUSCH), wherein the length of the ACK/NACK information or the number of elements of the ACK/NACK bundling is determined according to the UL DAI value of a CC that the PUSCH belongs to.
