Abstract
A method of wireless communication includes configuring a virtual cell identifier (ID) for a user equipment (UE). The method determines a first candidate for an enhanced physical downlink control channel (ePDCCH) for the UE. The method also determines a first virtual cell ID for the first candidate. Furthermore, the method scrambles the ePDCCH based on the first virtual cell ID and transmits, to the UE, the scrambled ePDCCH using the first candidate.
Claims56
A method of wireless communication, comprising:
- configuring at least one virtual cell identifier (ID) for a user equipment (UE);
- determining a first candidate for an enhanced physical downlink control channel (ePDCCH) for the UE;
- determining a first virtual cell ID for the first candidate;
- scrambling the ePDCCH based on the first virtual cell ID;
- and
- transmitting, to the UE, the scrambled ePDCCH using the first candidate.
A method of wireless communication, comprising:
- determining a first set of decoding candidates for an enhanced physical downlink control channel (ePDCCH);
- determining a first virtual cell identifier (ID) for the first set of decoding candidates;
- and
- decoding the ePDCCH based at least in part on the first virtual cell ID and the determined first set of decoding candidates.
An apparatus for wireless communications, comprising:
- means for configuring at least one virtual cell identifier (ID) for a user equipment (UE);
- means for determining a first candidate for an enhanced physical downlink control channel (ePDCCH) for the UE;
- means for determining a first virtual cell ID for the first candidate;
- means for scrambling the ePDCCH based on the first virtual cell ID;
- and
- means for transmitting, to the UE, the scrambled ePDCCH using the first candidate.
