Title:
CHANNEL STATE INFORMATION FEEDBACK SCHEMES FOR FD-MIMO
Document Type and Number:
WIPO Patent Application WO/2016/105120
Kind Code:
A1
Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method of operating a user equipment (UE). The method includes receiving a configuration message comprising a reporting type of channel state information (CSI). The method further includes calculating, in response to the configuration message, a CSI report comprising at least one precoding matrix indicator (PMI) associated with a codebook including a plurality of vectors, wherein each vector in the codebook represents a selection of a pair of antenna ports and a co-phasing between two antenna ports of the pair. The method further includes transmitting the CSI report on an uplink channel.
