ADVANCED FEEDBACK AND REFERENCE SIGNAL TRANSMISSIONS FOR MIMO WIRELESS COMMUNICATION SYSTEMS

WIPO Patent Application WO/2016/148464

A1

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 user equipment (UE) capable of communicating with a base station includes a transceiver configured to receive a signal comprising a CSI process configuration, wherein the CSI process configuration comprises a plurality of CSI-RS resource configurations to identify CSI-RS resources, and a controller configured to derive a first PMI index, i11 utilizing a first non-precoded CSI-RS on a first non-precoded CSI-RS resource, derive a second PMI index, i12 utilizing a second non-precoded CSI-RS on a second non-precoded CSI-RS resource, derive a third PMI index, i2 utilizing a beamformed CSI-RS on a beamformed CSI-RS resource, and cause the transceiver to transmit a CSI feedback comprising the three PMI indices i11, i12 and i2 to the base station. A base station capable of communicating with UE a transmitter configured to transmit a signal comprising a CSI process configuration, wherein the CSI process configuration comprises a plurality of CSI-RS resource configurations.
