Abstract
A User Equipment (UE) monitors a set of Physical Downlink Control Channel (PDCCH) candidates for control information received from a base station at subframe k. The set of PDCCH candidates to monitor are defined in terms of search spaces. The UE monitors a UE-specific search space, among the search spaces, at each of aggregation levels (L) of 1, 2, 4 and 8 control channel elements (CCEs), the CCE being a resource unit comprising a specific number of resource elements and used for transmission of the control information. The L CCEs correspond to a first PDCCH candidate among the set of PDCCH candidates of the search space at a subframe k are located at positions given by: L*{(Y)mod(floor(C))}+i, wherein i−0, . . . , L−1, where Yis defined by: Y−(A*Y+B) mod D. The variable C is determined based on the number of CCEs (N) divided by the aggregation level (L), and A, B, and D are predetermined constant values predetermined regardless of the aggregation levels L. The UE decodes the control information of the PDCCH.
