UPLINK CONTROL INFORMATION TRANSMISSION METHOD AND APPARATUS IN MULTI-CARRIER SYSTEM |
摘要 |
<p>A method for transmitting uplink control information of a user equipment in a multi-carrier system is provided. The method includes: transmitting each of acknowledgement/not-acknowledgement (ACK/NACK) for downlink data transmitted by a base station through multiple downlink component carriers; and transmitting channel state information indicating a state of a downlink channel to the base station, wherein each of the ACK/NACK and the channel state information are allocated to the same uplink control channel resource in a subframe, and if each of the ACK/NACK and the channel state information are reserved to be transmitted on the same subframe, each of the ACK/NACK only is transmitted. Accordingly, a user equipment can transmit uplink control information while preserving a single-carrier property of an uplink signal in a multi-carrier system using carrier aggregation.</p> |
