METHOD AND APPARATUS FOR TRANSRECEIVING DOWNLINK SIGNAL BY CONSIDERING ANTENNA PORT RELATIONSHIP IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus for transmitting or receiving a downlink signal by considering an antenna port relationship. A method for user equipment receiving a physical downlink shared channel (PDSCH) signal in the wireless communication system, according to one embodiment of the present invention, comprises the steps of: determining a start symbol index of the PDSCH from the downlink subframe; and receiving the PDSCH signal based on the start symbol index. When the DCI is comprised according to DCI format 1A, and the downlink subframe is a multicast broadcast single frequency network (MBSFN) subframe, the start symbol index can be determined depending on a PDSCH start symbol value which is included in a PDSCH resource element mapping and Quasi co-location indicator (PQI) that is established by an upper layer.

1. A method for receiving a physical downlink shared channel (PDSCH) signal by a user equipment (UE) in a wireless communication system, the method comprising:
determining a start symbol index of the PDSCH in a downlink subframe; and receiving the PDSCH signal based on the start symbol index, wherein the PDSCH is scheduled by downlink control information (DCI), and wherein when the DCI is configured according to DCI format 1A, and the downlink subframe is a Multicast Broadcast Single Frequency Network (MBSFN) subframe, the start symbol index is determined according to a PDSCH start symbol value contained in a PDSCH resource element mapping and Quasi co-location Indicator (PQI) parameter set configured by a higher layer.
