在无线通信系统中通过考虑天线端口关系收发下行链路信号的方法和设备
摘要：
本发明涉及一种无线通信系统，并且更加特别地，公开一种用于通过考虑天线端口关系发送或者接收下行链路信号的方法和设备。根据本发明的一个实施例的用于在无线通信系统中用户设备解码增强的物理下行链路控制信道(EPDCCH)的方法包括下述步骤：确定EPDCCH的天线端口的准共置(QCL)；和基于关于EPDCCH的天线端口的QCL解码EPDCCH。用户设备能够基于关于PDSCH的QCL假定的类型确定在EPDCCH解调参考信号的天线端口与不同的参考信号的天线端口之间的QCL假定。
摘要（英）：

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 decoding an enhanced physical downlink control channel (EPDCCH) in the wireless communication system, according to one embodiment of the present invention, comprises the steps of: determining a quasi co-location (QCL) of an antenna port of the EPDCCH; and decoding the EPDCCH based on the QCL with respect to the antenna port of the EPDCCH. The user equipment can determine a QCL assumption between an antenna port of an EPDCCH demodulation reference signal and an antenna port of a different reference signal based on the type of a QCL assumption with respect to a PDSCH.
