    Abstract: 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.

    Abstract translation: 无线通信系统技术领域本发明涉及一种无线通信系统，更具体地，涉及考虑天线端口关系发送或接收下行链路信号的方法和装置。 根据本发明的一个实施例，在无线通信系统中使终端能够接收物理下行链路共享信道（PDSCH）信号的方法可以根据预定优先级确定PDSCH起始符号索引并通过其接收PDSCH信号。 当PDSCH资源元素映射和准协同指示符（PQI）参数集中包含的PDSCH起始符号值由上层确定时，可以确定PDSCH起始符号索引。 当包含在PQI参数组中的PDSCH起始符号值不由上层确定时，可以根据接收PDSCH的小区的PDSCH开始符号值来确定PDSCH起始符号索引。
