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.
Claims8
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.
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.
