METHODS AND APPARATUS FOR DOWNLINK CONTROL CHANNELS TRANSMISSIONS IN WIRELESS COMMUNICATIONS SYSTEMS |
| 摘要 |
An antenna port for an extended Physical Downlink Control CHannel (ePDCCH) transmission is determined based on at least an identifier for a leading extended Control Channel Element (eCCE) within the ePDCCH and an identifier for a user equipment (UE) to receive the ePDCCH transmission, and based on whether the ePDCCH transmission is localized or distributed. The determined antenna port is a DeModulation Reference Signal (DMRS) port to which the UE is assigned. Symbols are mapped in sequence to resource elements (REs) and transmitted via the determined antenna port to the UE. |

1. A base station, comprising:
a controller configured to determine a DeModulation Reference Signal (DMRS) antenna port for an extended Physical Downlink Control CHannel (ePDCCH) transmission based on an index for a first extended Control Channel Element (eCCE) within the ePDCCH and an identifier for a user equipment (UE) to receive the ePDCCH transmission; and a transmitter configured to transmit symbols via the determined DMRS antenna port to the UE. |
