METHOD AND DEVICE FOR TRANSMITTING REFERENCE SIGNAL SEQUENCE

摘要

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.

1. A method for transmitting a reference signal sequence at a UE or a base station serving the UE, comprising:
determining a position of an enhanced control channel element (eCCE) or an enhanced resource element group (eREG) mapped to an enhanced physical downlink control channel (ePDCCH) in a resource block pair; determining, according to a corresponding relationship between a position of the eCCE or the eREG in the resource block pair and an antenna port of the reference signal, the antenna port of the reference signal, wherein 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 comprises that the positions of at least two eCCEs or at least two eREGs correspond to one of antenna ports of the reference signal; and transmitting a reference signal sequence over the antenna port of the reference signal.
