METHOD AND APPARATUS FOR CHANNEL STATE INFORMATION REFERENCE SIGNAL(CSI-RS)

WIPO Patent Application WO/2018/174695

A1

Methods and apparatuses for channel state information reference signal (CSI-RS) reporting. A method for operating a user equipment (UE) includes receiving and decoding higher-layer configuration information for N CSI reporting settings and M Resource settings. The method also includes receiving downlink control information (DCI) that includes a DCI field for requesting aperiodic CSI reporting. The method further includes calculating a CSI according to the configuration information and the DCI and transmitting the calculated CSI on an uplink (UL) channel. N is at least one, M is greater than one, and the DCI field includes a selection of one out of XSTATE configured states.
