Abstract: A method and system to decode PDCCH in LTE advanced systems is disclosed. The method adds the adjacent carrier information as LTE-Advanced bits in the PDCCH. The method proposes two approaches such as circular linked list and scrambled approach in adding the adjacent carrier information in the PDCCH. These approaches provide information of all the scheduled PDCCH for an UE. A circular linked list informs the starts position of adjacent PDCCH where UE has its data. Scrambling approach has all the scheduled PDCCH information in current carrier with different scrambling code which is known by the UE. Therefore, by decoding only current carrier UE knows PDCCHs that are scheduled for its data. The method reduces the complexity to a great extent with increase in little overhead.
