ENHANCED CHANNEL STATE INFORMATION REPORTING FOR DOWNLINK CONTROL CHANNEL

摘要

The present invention provides methods, apparatuses and a computer program product for enhanced CSI reporting for ePDCCH. The present invention includes deriving, at a user equipment, channel state information for estimating the downlink channel state relevant to downlink control channel, generating, at the user equipment, a channel state information report relevant to downlink control channel including a channel quality indicator and frequency domain information, wherein the channel quality indicator is related to link adaptation parameters, and transmitting the channel state information report relevant to downlink control channel to a base station.
