Method for efficiently transmitting physical channel in multi-carrier aggregation state to support broadband
First Claim
1. A method for transmitting data by a user equipment (UE) in a wireless access system supporting multi-carriers, the method comprising:
- receiving an uplink (UL) grant information for a first UL component carrier (CC) from a base station (BS) through a first downlink (DL) CC among a plurality of DL CCs, wherein the first UL CC is linked with a second DL CC other than the first DL CC;
transmitting UL data to the BS through UL resources of the first UL CC indicated by the UL grant information; and
receiving, from the base station and through the first DL CC through which the UL grant information was received, feedback information indicating a reception status of the transmitted UL data,wherein the first DL CC among the plurality of DL CCs is specified as a DL CC for receiving the feedback information.

Abstract
The present invention relates to a wireless connection system, and more specifically to a method for efficiently transmitting a control channel in a multi-carrier aggregation state. According to one aspect of the invention, a method for enabling a terminal to transmit data in a broadband wireless connection system that supports multiband comprises the steps of: receiving uplink acknowledgement information from a base station through a first downlink component carrier among plural downlink component carriers available in the terminal; transmitting data to the base station through an uplink resource indicated by the uplink acknowledge information; and receiving feedback information from the base station through the first control channel of the first downlink component carrier, wherein the feedback information indicates whether there is an error in the reception of the transmitted data.

9. A user equipment (UE) operated in a wireless access system supporting multi-carriers, the UE comprising:
-
a processor; and a radio frequency (RF) module for transceiving a radio frequency (RF) signal externally under a control of the processor, wherein the processor, upon receiving an uplink (UL) grant information for a first UL component carrier (CC) from a base station (BS) through a first downlink (DL) CC among a plurality of DL CCs, transmits UL data to the BS through UL resources of the first UL CC indicated by the UL grant information, and receives, from the base station and through the first DL CC through which the UL grant information was received, feedback information indicating a reception status of the transmitted UL data, wherein the first UL CC is linked with a second DL CC other than the first DL CC, and wherein the first DL CC among the plurality of DL CCs is specified as a DL CC for receiving the feedback information. - View Dependent Claims (10, 11, 12)
