EPDCCH candidate determining method and device
The present invention discloses an enhanced physical downlink control channel (EPDCCH) candidate determining method and device, and relates to the field of wireless communications, so as to avoid EPDCCH blocking and improve reliability of control information transmission. The method of the present invention includes: determining an EPDCCH resource set p in a subframe k, where the EPDCCH resource set p includes NECCE,p,k=q×r enhanced control channel elements (ECCEs), an EPDCCH candidate of an EPDCCH with an aggregation level being L corresponds to L ECCEs having consecutive reference numerals, and an EPDCCH candidate is capable of carrying an EPDCCH; and determining the number of EPDCCH candidates at the aggregation level L of a carrier corresponding to an index Cellindex and an ECCE corresponding to each EPDCCH candidate, where the ECCE corresponding to each EPDCCH candidate at the aggregation level L is related to the index Cellindex.
