Abstract:
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.
