Abstract

本发明提供一种参考信号序列的传输方法及设备，包括：确定ePDCCH映射的eCCE或eREG在资源块对中的位置；根据所述eCCE或所述eREG在所述资源块对中的位置与参考信号的天线端口的对应关系，确定所述参考信号的天线端口；在所述参考信号的天线端口传输参考信号序列；其中，所述eCCE或所述eREG在所述资源块对中的位置与所述参考信号的天线端口的对应关系包括至少二个eCCE或至少二个eREG的位置与所述参考信号的天线端口的一个对应。应用本发明实施例提供的技术方案，可以解决在天线端口有限的情况下，不能通过天线端口传输参考信号序列而降低了采用参考信号序列对ePDCCH进行信道估计的能力的问题。
