Abstract:
1. A method of wireless communication, comprising: configuring at least one virtual cell identifier (ID) for an enhanced physical downlink control channel (ePDCCH) to be transmitted to a user equipment (UE), each virtual cell ID being separately configured from a physical cell ID of a serving cell, and the ePDDCCH being associated with at least one ePDCCH resource set of a plurality of ePDCCH resource sets configured for the UE; determining a first ePDCCH decoding candidate from a plurality of ePDCCH decoding candidates used by the UE to attempt to decode the ePDCCH in a first search space; determining a first virtual cell ID for the first ePDCCH decoding candidate, the first virtual cell ID being associated with the at least one ePDCCH resource set of the plurality of ePDCCH resource sets configured for the UE; scrambling the ePDCCH with a scrambling sequence that is based at least in part on the first virtual cell ID; and transmitting, to the UE, the scrambled ePDCCH using the first ePDCCH decoding candidate.
