Title:
APPARATUS AND METHOD FOR TRANSCEIVING CHANNEL STATE INFORMATION
Document Type and Number:
WIPO Patent Application WO/2017/217819
Kind Code:
A1
Abstract:
A method of an evolved Node B (eNB) in a wireless environment is provided. The method includes receiving, from a user equipment (UE), a plurality of channel state information (CSI) feedback respectively corresponding to a plurality of CSI processes that are respectively allocated a plurality of precoding matrix indexes (PMIs), determining a modulation and coding scheme (MCS) value based on the plurality of received CSI feedback, and transmitting, to the UE, data modulated based on the determined MCS value by cyclically using the plurality of PMIs, wherein the plurality of CSI feedback may each include information on a channel quality indication (CQI) as to a PMI allocated to a CSI process corresponding to each of the plurality of CSI feedback.
