Method and apparatus for transmitting/receiving downlink signal considering antenna port relationship in wireless communication system

摘要

The present invention relates to a wireless communication system, and more specifically, to a method and an apparatus for transmitting or receiving a downlink signal considering an antenna port relationship. The method for enabling a terminal to receive a physical downlink sharing channel (PDSCH) signal in the wireless communication system according to one embodiment of the present invention can determine a PDSCH start symbol index according to the predetermined priority and receive the PDSCH signal therethrough. The PDSCH start symbol index can be determined when a PDSCH start symbol value included in a PDSCH resource element mapping and Quasi co-location Indicator (PQI) parameter set is determined by an upper layer. The PDSCH start symbol index can be determined according to the PDSCH start symbol value for a cell receiving the PDSCH when the PDSCH start symbol value included in the PQI parameter set is not determined by the 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, when a PDSCH start symbol value contained in a PDSCH resource element mapping and Quasi co-location Indicator (PQI) parameter set is configured for the UE by a higher layer, the start symbol index is determined according to the PDSCH start symbol value contained in the PQI parameter set, wherein, when the PDSCH start symbol value contained in the PQI parameter set is not configured for the UE by the higher layer, and a PDSCH start symbol value for a cell via which the PDSCH is received is configured by the higher layer, the start symbol index is determined according to the PDSCH start symbol value for the cell via which the PDSCH is received.
