Title:
METHOD AND APPARATUS FOR REDUCED FEEDBACK MIMO
Document Type and Number:
WIPO Patent Application WO/2017/082634
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). Methods and apparatuses for CSI reporting mechanisms are provided. A user equipment (UE) includes a transceiver and a processor operably connected to the transceiver. The transceiver is configured to receive transmission scheme configuration information, codebook configuration information, and eMIMO-Type configuration information. The processor is configured to calculate, in response to receipt of configuration information that indicates an open-loop diversity operation, a first precoding matrix indicator (PMI) i1 from a codebook. The codebook includes two PMIs i1 and i2 and is determined based on the codebook configuration information. The transceiver is further configured to report the first PMI i1 by transmitting the first PMI i1 on an uplink channel.
