Abstract A method for receipt of at least one Downlink Control Information (DCI) in a communication system supporting Carrier Aggregation (CA), the method comprising the steps of: receiving information representative of presence of carrier indicator by higher layer signaling from a Node B; receiving information representative of at least one cell index by higher layer signaling from the Node B; defining an UE specific search space based on aggregation level, an UE ID, and at least one carrier indicator value, where the UE specific search space includes a set of Physical Downlink Control CHannel (PDCCH) candidates based on the aggregation level; decoding at least one PDCCH including at least one DCI respectively by the UE ID; and acquiring the at least one DCI, wherein the at least one carrier indicator value is based on the at least one cell index. 4810365 1 (GHMailersnP89559A[J1 29/10/2013 [Fig. 16] 0 NODE 8 BROADCASTS PDCCH- SIZE CONFIGURATIONS 1610 FDCCH SIZE CONFIGURATION 1,2, 3. 4), 22.3, 4, 5}, (3, 4, 5, 61. f(4. 5, 6. 71 13,4,5,61 1620 NODE 3 TRANSMITS POAICH 1630 liE DETERMINES POOCH SIZE [Fig. 17] c CD C.
