Abstract:
Embodiments of the present invention provide an interference cancellation method for an enhanced physical downlink control channel E-PDCCH, comprising steps of: (1) allocating different orthogonal covering code OCC sequences to different cells and/or different users; and (2) combining a plurality of control channel elements CCEs constituting one PDCCH with a cell-specific OCC sequence and/or a user-specific OCC sequence respectively, so as to enable a user equipment to cancel interference on the PDCCH.
