Abstract: A method by which a base station transmits a reference signal to a terminal in a wireless communication system is disclosed. Particularly, the method comprises the steps of determining a reference signal resource interval expressed as a unit of one or more resource blocks (RBs), setting reference signal resources for a downlink bandwidth defined by a plurality of RBs, according to the reference signal resource interval, and transmitting the reference signal to the terminal by using the set reference signal resources, wherein the reference signal resource interval is determined on the basis of the number of reference signal antenna ports for which quasi co-location (QCL) can be assumed.

Abstract: A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system. The method is performed by a User Equipment (UE) configured to use a Physical Uplink Control Channel (PUCCH) format 3. The UE determines a PUCCH format and a PUCCH resource through which ACK/NACK information for downlink transmission in a downlink subframe set including M downlink subframes is to be transmitted, wherein M>1. The UE transmits the ACK/NACK information using the PUCCH format and the PUCCH resource in one uplink subframe. A plurality of serving cells are configured for the UE and include one Primary Cell (PCell) and at least one Secondary Cell (SCell).
