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
UE: receives radio resource control configuration associated with a CSI report; receives trigger information for triggering a report of a set of CSI values configured by means of the radio resource control configuration; determines a measurement resource for the CSI report and an uplink resource for the CSI report, on the basis of the radio resource configuration and trigger information; and performs a partial CSI report in which only a part of the set of CSI values is calculated and the calculated CSI value is transmitted in the uplink resource, on the basis of which the time differential between the measurement resource and the uplink resource satisfies a predetermined condition.
1 . A method performed by a user equipment (UE), the method 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 a set of CSI values configured based on the RRC configuration information 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.
2 . The method of claim 1 ,
wherein the predetermined condition comprises:
the time difference is smaller than a CSI computation time T 1 predefined based on full CSI reporting in which the entirety of the set of CSI values is calculated and greater than a time T 2 based on an end of the measurement resource for the partial CSI reporting.
3 . The method of claim 2 , further comprising:
based on that the time difference is greater than T 1 , performing the full CSI reporting,
wherein performing of the full CSI reporting comprises calculating the entirety of the set of CSI values is calculated and transmitting the calculated set of CSI values on the uplink resource.
4 . The method of claim 1 ,
wherein the measurement resource is not later than the uplink resource.
5 . The method of claim 1 ,
wherein the RRC configuration information comprises configuration information related to the partial CSI reporting.
6 . 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.
7 . 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.
8 . The BS of claim 7 ,
wherein the predetermined condition comprises:
the time difference is smaller than a CSI computation time T 1 predefined based on full CSI reporting in which the entirety of the set of CSI values is calculated and greater than a time T 2 based on an end of the measurement resource for the partial CSI reporting.
9 . The BS of claim 8 ,
wherein,
based on that the time difference is greater than T 1 , the full CSI reporting is performed by the UE, and
wherein, based on that the full CSI reporting is performed, the entirety of the set of CSI values is calculated by the UE and the calculated set of CSI values is received on the uplink resource.
10 . The BS of claim 7 ,
wherein the measurement resource is not later than the uplink resource.
11 . The BS of claim 7 ,
wherein the RRC configuration information comprises configuration information related to the partial CSI reporting.
