Method for transmitting channel state information report, user equipment, processing device and storage medium, and method for receiving channel state information report and base station

A user equipment (UE), the UE comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• receiving radio resource control (RRC) configuration information related to channel state information (CSI) reporting;
• receiving downlink control information (DCI) that triggers the CSI reporting;
• based on the RRC configuration information and the DCI, determining a measurement resource for the CSI reporting and an uplink resource for the CSI reporting;
• and
• based on that a time difference between the measurement resource and the uplink resource satisfies a predetermined condition, performing partial CSI reporting,
• wherein, performing of the partial CSI reporting comprises calculating only part of the set of CSI values and transmitting an indicator for the partial CSI reporting and partial CSI including the calculated CSI values on the uplink resource, and
• wherein the indicator for the partial CSI reporting indicates whether the partial CSI reporting is performed and the indicator is encoded separately from the partial CSI.

A base station (BS), the BS comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• transmitting, to a user equipment (UE), radio resource control (RRC) configuration information related to channel state information (CSI) reporting;
• transmitting, to the UE, downlink control information (DCI) that triggers the CSI reporting;
• and
• receiving on an uplink resource for the CSI reporting, from the UE, an indicator for a partial CSI reporting and partial CSI including only part of a set of CSI values configured based on the RRC configuration information,
• wherein, based on that a time difference between a measurement resource for the CSI reporting and an uplink resource for the CSI reporting determined based on the RRC configuration information and the DCI satisfies a predetermined condition, the partial CSI reporting is performed by the UE, and
• wherein the indicator for the partial CSI reporting indicates whether the partial CSI reporting is performed and the indicator is encoded separately from the partial CSI.
