Abstract
The present invention relates to various methods for performing quasi co-location (QCL) and apparatuses supporting the same. As an embodiment of the present invention, a method for performing quasi co-location (QCL) for a new carrier type (NCT) by a terminal in a wireless access system may include the steps of: receiving a higher layer signal including a QCL reference CRS information parameter indicating CRS information of a reference carrier; receiving a physical downlink control channel (PDCCH) signal including a PDSCH remapping and quasi co-location indicator (PQI) field; receiving a CSI-RS of a QCLed NCT and a CRS of a reference carrier on the basis of a PQI field and a QCL reference CRS information parameter; and performing frequency tracking of the NCT and the reference carrier on the basis of the CSI-RS of the NCT and the CRS of the reference carrier.
