OG exemplary drawing
 
1. A user equipment (UE) for decoding control information, the UE comprising:
a receiver configured to receive control information through a Physical Downlink Control Channel (PDCCH) at a subframe k;
a decoder configured to monitor a set of PDCCH candidates for the received control information, the set of PDCCH candidates being defined in terms of search spaces,
wherein:
the decoder is configured to monitor a UE-specific search space of the PDCCH, among the search spaces, at multiple levels of control channel elements (CCEs),
the CCE is a resource unit including a number of resource elements for transmission of the control information,
the UE-specific search space is given based on a variable of Yk for the subframe k defined by: Yk=(A*Yk-1) mod D, where A and D are predetermined values, and
Yk in the subframe k is based on an UE identifier.
