Claim of US Patent No. 9,504,028

1. A method of determining a blind detection mode comprising:
an evolved Node B, eNB, determining a blind Enhanced Physical Downlink Control Channel, E-PDCCH, detection mode of a User
Equipment, UE, in a sub-frame according to system configuration information, and a blind detection capability of the UE; and

the eNB notifying the UE of the determined blind E-PDCCH detection mode of the UE in the sub-frame;
wherein the eNB determining the blind E-PDCCH detection mode of the UE in the sub-frame according to the system configuration
information, and the blind detection capability of the UE comprises:

the eNB determining a set of Enhanced-Control Channel Element, E-CCE, aggregation levels, at which the UE needs to perform
blind E-PDCCH detection in the sub-frame, according to the system configuration information, and the blind detection capability
of the UE; and

the eNB determining a number of times, that blind detection is performed, corresponding to each E-CCE aggregation level in
the set of E-CCE aggregation levels.
