Patent ID: 11881905
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 5:
6. A base station (BS) comprising:
a transceiver configured to transmit, to a user equipment (UE), configuration information on an aperiodic channel state information (CSI) reporting, configuration information on a non-zero power channel state information reference signal (NZ CSI-RS) resource for channel measurement, configuration information on a zero power channel state information reference signal (ZP CSI-RS) resource for interference measurement, configuration information on a NZP CSI-RS resource for interference measurement, and configuration information on a report for a layer 1 signal-to-interference-plus-noise ratio (L1-SINR) measurement; and
a processor operably coupled to the transceiver, the processor configured to determine at least one reference signal on the NZP CSI-RS resource for channel measurement, the ZP CSI-RS resource for interference measurement, and the NZP CSI-RS resource for interference measurement,
wherein the transceiver is further configured to:
transmit, to the UE, the at least one reference signals; and
receive, from the UE, the aperiodic CSI reporting comprising information on at least one L1-SINR value based on the L1-SINR measurement on the at least one reference signal, and

wherein the at least one L1-SINR value comprises a main SINR value and a differential SINR value.
