Abstract

A method and an apparatus of transmitting control information in a wireless communication systema are provided. The method includes transmitting first control information and second control information through an uplink component carrier (UL CC), wherein the first control information is for a first downlink component carrier (DL CC), and the second control information is for a second DL CC.

Claims

1. A method of transmitting an acknowledgement (ACK)/negative acknowledgement (NACK) from a user equipment (UE) supporting carrier aggregation in a multiple carrier system, the method comprising:

receiving, by a UE, a first downlink (DL) channel on a first DL component carrier (CC) and a second DL channel on a second DL CC;

determining, by the UE, a single uplink (UL) CC used for transmitting feedback information for the first DL channel and the second DL channel via a physical uplink control channel (PUCCH); and

transmitting, by the UE to a base station (BS), an ACK/NACK feedback indicating both ACK/NACK information for the first DL channel and ACK/NACK information for the second DL channel on the single UL CC,

wherein the ACK/NACK feedback is transmitted both on a first PUCCH resource of a first antenna port and on a second PUCCH resource of a second antenna port, and

wherein the first antenna port and the second antenna port are configured for the UE.

2. The method of claim 1, wherein the ACK/NACK feedback includes a channel quality indicator (CQI) of at least one of the first DL channel and the second DL channel.

3. The method of claim 2, further comprising:

receiving, from the BS, a periodicity of the CQI,

wherein the CQI is transmitted on the PUCCH periodically.

4. The method of claim 3, wherein the resource used for the transmission of the PUCCH is determined by the BS.

5. A mobile station for transmitting an acknowledgement (ACK)/negative acknowledgement (NACK) in a multiple carrier system, comprising:

a radio frequency (RF) unit configured to;

support carrier aggregation associated with a plurality of downlink (DL) component carriers (CCs); and

receive a first downlink (DL) channel on a first DL component carrier (CC) and a second DL channel on a second DL CC; and

a processor operably coupled with the RF unit and configured to;

determine a single uplink (UL) CC used for transmitting feedback information for a first DL channel and a second DL channel via a physical uplink control channel (PUCCH); and

transmit, to a base station (BS), an ACK/NACK feedback indicating both ACK/NACK information for the first DL channel and ACK/NACK information for the second DL channel on the single UL CC,

wherein the ACK/NACK feedback is transmitted both on a first PUCCH resource of a first antenna port and on a second PUCCH resource of a second antenna port, and

wherein the first antenna port and the second antenna port are configured for the mobile station.

6. The mobile station of claim 5, wherein the ACK/NACK feedback includes a channel quality indicator (CQI) of at least one of the first DL channel and the second DL channel.

7. The mobile station of claim 6, wherein the RF unit is further configured to:

receive, from the BS, a periodicity of the CQI,

wherein the CQI is transmitted on the PUCCH periodically.

8. The mobile station of claim 7, wherein the resource used for the transmission of the PUCCH is determined by the BS.
