METHOD AND APPARATUS FOR TRANSMITTING UPLINK DATA

摘要

Provided are a method and apparatus for transmitting uplink data. The method for transmitting data in a uplink subframe comprises the steps of: determining whether or not a hybrid automatic retransmission request-acknowledgement (HARQ-ACK) and uplink control information (UCI) are being simultaneously transmitted in the uplink subframe; selecting either the HARQ-ACK or UCI on the basis of the HARQ-ACK state for HARQ-ACK upon the occurrence of simultaneous transmission; and transmitting the selected HARQ-ACK or UCI in the uplink subframe.

1. A method for transmitting data in uplink subframe, the method comprising:
determining whether hybrid automatic retransmission request-acknowledgement (HARQ-ACK) and uplink control information (UCI) are simultaneously transmitted in the uplink subframe; selecting one of the HARQ-ACK and the UCI depending on the state of the HARQ-ACK, if the simultaneous transmission occurs; and transmitting the selected one of the HARQ-ACK and the UCI in the uplink subframe, wherein the UCI includes at least one of periodic reporting channel state information (CSI) and sounding reference signal (SRS), wherein the state of the HARQ-ACK is one of ACK, non-acknowledgement (NACK), and discontinuous transmission (DTX), and wherein the UCI is selected and transmitted in the uplink subframe if the state of the HARQ-ACK is the DTX or the NACK.
