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

摘要

A method is provided for receiving uplink control information (UCI) in a wireless access system supporting a carrier aggregation. An evolved Node-B (eNB) transmits, to a user equipment (UE), two or more physical downlink shared channels (PDSCHs) via two or more downlink component carriers, respectively. The eNB receives, from the UE, the UCI for the two or more downlink component carriers. The UCI includes acknowledgement information and channel quality information (CQI) for each of the two or more downlink carriers. The UCI is performed by using a channel coding with respect to the UCI according to a payload size of the UCI when the UCI is transmitted by using a physical uplink control channel (PUCCH) format 3. The UCI is performed by using a rate matching with respect to the channel coded UCI for the PUCCH format 3.

1. A method of receiving uplink control information (UCI) in a wireless access system supporting a carrier aggregation, the method performed by a evolved Node-B (eNB) and comprising:
transmitting, to a user equipment (UE), two or more physical downlink shared channels (PDSCHs) via two or more downlink component carriers, respectively; and receiving, from the UE, the UCI for the two or more downlink component carriers, wherein the UCI includes acknowledgement information and channel quality information (CQI) for each of the two or more downlink carriers, wherein the UCI is performed by using a channel coding with respect to the UCI according to a payload size of the UCI when the UCI is transmitted by using a physical uplink control channel (PUCCH) format 3, wherein the UCI is performed by using a rate matching with respect to the channel coded UCI for 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.
