Method and apparatus for transmitting channel quality control information using PUCCH format 3 in a wireless access system

摘要

A method of transmitting uplink control information (UCI) in a wireless access system supporting carrier aggregation. A user equipment (UE) receives two or more physical downlink shared channels (PDSCHs) via two or more downlink component carriers, respectively. The UE performs channel coding with respect to the UCI according to a payload size of the UCI including acknowledgement information and channel quality information (CQI) for each of the two or more downlink carriers. The UE performs rate matching with respect to the channel coded UCI for a physical uplink control channel (PUCCH) format 3. The UE transmits the rate matched UCI using the PUCCH format 3.

1. A method of transmitting uplink control information (UCI) in a wireless access system supporting carrier aggregation, the method performed by a user equipment (UE) and comprising:
receiving two or more physical downlink shared channels (PDSCHs) via two or more downlink component carriers, respectively; performing channel coding with respect to the UCI according to a payload size of the UCI including acknowledgement information and channel quality information (CQI) for each of the two or more downlink component carriers; performing rate matching with respect to the channel coded UCI for a physical uplink control channel (PUCCH) format 3; and transmitting the rate matched UCI using the PUCCH format 3, wherein the channel coding is performed by using a (32, O) code when the payload size of the UCI is less than or equal to 11 bits, wherein the channel coding is performed by using two (32, O) codes when the payload size of the UCI is greater than or equal to 12 bits, and wherein ‘O’ is the payload size of the UCI.
