The present invention provides a method and device for transmitting a reference signal sequence. The method includes: determining a position of an eCCE or an eREG mapped to an ePDCCH in a resource block pair; determining, according to corresponding relationship between the position of the eCCE or the eREG in the resource block pair and the antenna port of the reference signal; and transmitting a reference sequence over the antenna port of the reference signal, herein, the corresponding relationship between the position of the eCCE or the eREG in the resource block pair and the antenna port of the reference signal includes that the positions of at least two eCCEs or at least two eREGs correspond to one of the antenna ports of the reference signal. The technical solution provided in embodiments of the present invention can solve the problem that the capability of performing channel estimation for an ePDCCH by using a reference signal sequence is reduced since the reference signal sequence cannot be transmitted through an antenna port in the case that the number of the antenna ports is limited. |
