METHOD AND APPARATUS FOR CONFIGURING AND DETECTING AN IMPROVED DOWNLINK CONTROL CHANNEL, IMPROVED BASE STATION AND TERMINAL Russian patent published in 2016 - IPC H04W72/04 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to a wireless communication, which configures and detects an enhanced downlink control channel, and allows an ePDCCH to have stronger stability and configuration flexibility. Enhanced downlink control channel configures K ePDCCH detection clusters for a terminal and comprises: independent 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 independent 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.

EFFECT: invention allows an ePDCCH to have stronger stability and configuration flexibility.
