The present invention relates to rapid search space reconfiguration for E-PDCCH in wireless communication system to avoid flashlight interferences from neighbouring cells and to allocate the E-PDCCH on the best physical resource blocks in frequency fluctuation dominated scenarios. The turbine blade includes a platform with an airfoil extending upwardly from the airfoil and a root portion extending downwardly from the platform. After merging of the cover with the book block, a measuring procedure for measuring a mutual actual position of cover relative to book block. The input circuit may be embodied in a memory device and in memory systems.
