ePDCCH Transmitting And Receiving Method, Base Station And User Equipment
First Claim
1. An enhanced physical downlink control channel (ePDCCH) transmitting method, comprising:
- a base station determining a candidate enhanced control channel element (eCCE) index for transmitting an ePDCCH in an ePDCCH resource set;
the base station determining an enhanced resource element group (eREG) index to which the candidate eCCE index for transmitting the ePDCCH is mapped;
the base station sending the ePDCCH to a terminal according to a determined result; and
wherein, the eCCE is a discretely mapped eCCE (D-eCCE), and a mapping relationship between the eCCE index and the eREG index comprises at least one of the following;
the ePDCCH resource set comprising k D-eCCE groups divided according to a sequence of D-eCCE indexes, in a same D-eCCE group, each D-eCCE being mapped to a same eREG index group, each eREG index group comprising a plurality of eREG indexes, and when different D-eCCEs of the same D-eCCE group are mapped to a same eREG index, the same eREG index corresponding to the different D-eCCEs being located on different resource blocks.
