Abstract

本发明实施例提供了一种增强型下行控制信道的发送方法、检测方法和装置，所述方法包括：基站根据确定的移动台的聚合级别，选择为所述移动台分配的搜索空间中，对应所述聚合级别的一个候选位置，在所选择的候选位置上向所述移动台发送增强型下行控制信道(ePDCCH)(401)；基站根据预先设定的聚合级别为1时所分配的搜索空间中频域上最低的资源块上的驻留增强型控制信道元素(eCCE)的索引，以及预先设定的eCCE与天线端口之间的对应关系，确定导频参考符号的天线端口(402)；基站在所确定的天线端口对应的资源上向所述移动台发送所述导频参考符号(403)。本发明实施例提供的方法和装置，可以降低移动台进行信道估计的复杂度。
