Title:
無線通信システムにおける下りリンク制御チャネルのための参照信号アンテナポート決定方法及びそのための装置
Document Type and Number:
Japanese Patent JP5933039
Kind Code:
B2
Abstract:
Abstract: The present invention relates to a method of transmitting a downlink control channel including one or more control channel elements to a terminal by a base station in a wireless communication system. In particular, the method includes: allocating an antenna port of a demodulation-reference signal (DM-RS) to the one or more control channel elements that configure the downlink control channel; and transmitting the downlink control channel to the terminal by using the DM-RS of the allocated antenna port, wherein the antenna port of the DM-RS is determined on the basis of the number of control channel elements per resource block.
