METHOD AND APPARATUS OF DOWNLINK SIGNALING FOR PARTIALLY PRECODED CSI-RS AND CSI FEEDBACK |
摘要 |
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). User equipment (UE) is configured to receive two types of channel state information (CSI) reference signals (CSI-RS), the first containing more antenna ports and measured less often than the second. A first CSI report is based on first type CSI-RS and a second CSI report on the second type CSI-RS. The second type CSI-RS is at least partially precoded in response to the first CSI report, is precoded for the specific UE, and is transmitted more often than the first type CSI-RS, while the first type CSI-RS is not precoded. The first CSI report contains a first precoding matrix indicator (PMI) parameter and the second CSI report contains only a second PMI parameter of a two-PMI codebook, where the first PMI parameter is a long-term and wideband PMI. The first PMI is derived from measuring the first type CSI-RS in a plurality of subframes and resource blocks. |
