The present invention provides a method and device for transmitting a reference signal sequence. The method comprises: determining a position of an eCCE or an eREG mapped to an ePDCCH in a resource block pair; determining, according to correspondence between the position of the eCCE or the eREG in the resource block pair and an antenna port of a reference signal, the antenna port of the reference signal; and transmitting a reference signal sequence over the antenna port of the reference signal, the correspondence between the position of the eCCE or the eREG in the resource block pair and the antenna port of the reference signal comprising that the positions of at least two eCCEs or at least two eREGs correspond to one of 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 of limited antenna ports. |
