APPARATUS AND METHOD OF SOLVING CCE CONFUSION

摘要

PURPOSE: A method for canceling CCE(Control Channel Element) scrambling and apparatus thereof are provided to prevent CCE scrambling in a wireless communication system in order to process PDCCH. CONSTITUTION: A processor(122) receives a plurality of CCEs from a base station(110). The processor performs blind decoding by CCE aggregation. The processor confirms a CCE group level in PDCCH transmission based on a blind decoding result. A mapping method of control information is related to the CCE group level in PDCCH.
