Abstract
A User Equipment (UE) receives control information via a Physical Downlink Control Channel (PDCCH) at subframe k. A decoder monitors a set of PDCCH candidates 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 UE-specific search space is given based on a modulus operation using variables Yand C for the subframe k. Yis defined by: Y=(A*Y+B) mod D. C is determined based on the number of CCEs (N) divided by the aggregation level (L). A, B, and D are predetermined constant values regardless of the aggregation levels (L). Yis determined based on a UE identifier having 16-bits when k=0. The decoder decodes the control information of the PDCCH.
