Abstract

A method of generating Acknowledgement/Negative Acknowledgement (ACK/NACK) information by a user equipment (UE) in a wireless communication system is discussed. The method includes receiving, by the UE from a base station (BS), a plurality of codewords through a plurality of downlink frequency bands related to a plurality of downlink carriers, wherein the UE is configured with a 1-codeword mode or a 2-codeword mode for each of the plurality of downlink frequency bands independently, and wherein a number of supported codewords is one for the 1-codeword mode or two for the 2-codeword mode; determining, by the UE, a total number of ACK/NACK bits, wherein the total number of ACK/NACK bits is determined based on a total number of the plurality of downlink carriers and the number of supported codewords; and generating, by the UE, a sequence of the ACK/NACK bits based on the total number of the ACK/NACK bits.

Claims23

Dependent claims

A method performed by a user equipment (UE) for transmitting acknowledgement/negative acknowledgement (ACK/NACK) information in a wireless communication system, the method comprising:

receiving at least one transport block (TB) for at least one carrier aggregation (CA) downlink component carrier (DL CC) among a plurality of CA DL CCs that are configured for the UE in the wireless communication system;
generating the ACK/NACK information for the plurality of CA DL CCs, based on the at least one TB received for the at least one CA DL CC;
and
transmitting the ACK/NACK information via a physical uplink control channel (PUCCH),
wherein the plurality of CA DL CCs comprises (i) at least one first CA DL CC configured for a one-TB transmission mode, and (ii) at least one second CA DL CC configured for a two-TB transmission mode, and
wherein generating the ACK/NACK information for the plurality of CA DL CCs comprises:
concatenating ACK/NACK bits for the plurality of CA DL CCs based on (i) a CA DL CC index for each of the plurality of CA DL CCs, and (ii) a transmission mode for each of the plurality of CA DL CCs,
wherein concatenating the ACK/NACK bits for the plurality of CA DL CCs comprises concatenating (i) one ACK/NACK bit for each of the at least one first CA DL CC configured for the one-TB transmission mode, and (ii) two ACK/NACK bits for each of the at least one second CA DL CC configured for the two-TB transmission mode, and
wherein the ACK/NACK bits are concatenated such that ACK/NACK bits associated with CA DL CCs having smaller CA DL CC indices precede ACK/NACK bits associated with CA DL CCs having larger CA DL CC indices.
