Configuration and detection method and device for enhanced downlink control channel, evolved Node B and terminal

摘要

Disclosed is a configuration method for an enhanced downlink control channel, which configures K ePDCCH detection clusters for a terminal, including: independently configuring an antenna port index of a corresponding demodulation reference signal (DMRS) at the time of detection of each ePDCCH detection cluster or different transmission modes of ePDCCH detection clusters of the K ePDCCH detection clusters; and/or independently configuring a scrambling sequence index of the corresponding DMRS at the time of detection of each ePDCCH detection cluster or different transmission modes of ePDCCH detection clusters of the K ePDCCH detection clusters; and/or independently configuring the correlation between a corresponding DMRS scrambling sequence at the time of detection of each ePDCCH detection cluster or different transmission modes of ePDCCH detection clusters of the K ePDCCH detection clusters and a DMRS scrambling sequence of a physical downlink shared channel PDSCH, and the like. Disclosed at the same time are a detection method and device for an enhanced downlink control channel, a configuration device for an enhanced downlink control channel, a terminal and an evolved node B. The present invention allows an ePDCCH to have stronger stability and configuration flexibility.
