Method for Assigning Number of Control Channel Candidates and Number of Blind Detection Times, Base Station, and User Equipment

A base station, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory stores instructions to program the processor to:
• determine a first aggregation level set {L1i} comprising N aggregation levels for aggregating control channel elements (CCE) into Enhanced Physical Downlink Control Channels (EPDCCH), wherein i is a positive integer that ranges from 1 to N, and N is a positive integer;
• determine the number of EPDCCH candidates corresponding to each aggregation level in the set {L1i};
• determine a second aggregation level set {L2j} comprising M aggregation levels, wherein j is a positive integer that ranges from 1 to M, set {L2j} is a subset of set {L1i} and M is less than or equal to N, and the number of EPDCCH candidates corresponding to L2j in the set {L2j} is greater than or equal to the number of EPDCCH candidates corresponding to L2j in the set {L1i};
• and
• determine the number of EPDCCH candidates corresponding to each aggregation level in the set {L2j}.

A user equipment (UE), comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory stores instructions to program the processor to:
• determine a first aggregation level set {L1i} comprising N aggregation levels for aggregating control channel elements (CCE) into Enhanced Physical Downlink Control Channels (EPDCCH), wherein i is a positive integer that ranges from 1 to N, and N is a positive integer;
• determine the number of blind detection times corresponding to each aggregation level in the set {L1i};
• determine a second aggregation level set {L2j} comprising M aggregation levels, wherein j is a positive integer that ranges from 1 to M, set {L2j} is a subset of set {L1i} and M is less than or equal to N, and the number of blind detection times corresponding to L2j in the set {L2j} is greater than or equal to the number of blind detection times corresponding to L2j in the set {L1i};
• and
• determine the number of blind detection times corresponding to each aggregation level in the set {L2j}.
