Uplink control information transmitting/receiving method and device in a wireless communication system

摘要

The present invention relates to a method for a terminal to transmit acknowledgement information in a wireless communication system including: determining whether the transmission of a scheduling request is set in one uplink subframe, where acknowledgement information on downlink transmission in a downlink subframe set including M(M≧1) downlink subframes is to be transmitted; and transmitting the acknowledgement information by using a Physical Uplink Control Channel (PUCCH) format and the resource. Here, if there is no Semi-Persistent Scheduling releasing Physical Downlink Control Channel (PDCCH) in the downlink subframe set, if the acknowledgement information corresponds to only one Physical Downlink Shared Channel (PDSCH) indicated by the detection of a corresponding PDCCH received on only a Primary Cell in the downlink subframe set, and if a Downlink Assignment Index value of the PDCCH is 1, the acknowledgement information and the scheduling request may be transmitted using PUCCH format 1b.

1. A method for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a User Equipment (UE) configured to use Physical Uplink Control Channel (PUCCH) format 3 in a wireless communication system, the method comprising:
determining that transmission of a scheduling request is configured in one uplink subframe in which the PUCCH format 3 transmission of ACK/NACK information for downlink transmission in a downlink subframe set including M downlink subframes is to be transmitted, wherein M≧1; determining a PUCCH format and resource based on the determination that the scheduling request transmission is configured in the one uplink subframe; and transmitting the ACK/NACK information using the determined PUCCH format and resource, wherein, when the PUCCH format 3 transmission of the ACK/NACK information coincides with the one uplink subframe for the transmission of the scheduling request, the ACK/NACK information and the scheduling request are transmitted using PUCCH format 1b in the one uplink subframe when the ACK/NACK information corresponds only to one Semi-Persistent Scheduling (SPS) release Physical Downlink Control Channel (PDCCH) having a Downlink Assignment Index (DAI) value of 1 in the downlink subframe set or only to one Physical Downlink Shared Channel (PDSCH) indicated by detection of a corresponding PDCCH having a DAI value of 1 that is received only on a Primary Cell (PCell) in the downlink subframe set.
