Abstract

A user equipment may be configured to perform UE indication to temporarily suspend report occasions. In some aspects, the user equipment may receive report configuration information from a base station, the report configuration information identifying a report parameter to provide in a channel state information (CSI) report, and determine a predicted value of the report parameter based on a plurality of historic measurements. Further, the user equipment may determine to suspend transmission of the report parameter based on the predicted value, and transmit a report suspension message to the base station, the report suspension message indicating that the UE has implemented a temporary suspension of reporting of the report parameter in the CSI report.

Claims (49)

1. A method of wireless communication at a user equipment (UE), comprising:

receiving report configuration information from a base station, the report configuration information identifying a report parameter to provide in a channel state information (CSI) report and a periodicity for transmitting the CSI report;

determining, for one or more future reporting occasions that are based on the periodicity, a predicted value of the report parameter based on a plurality of historic measurements; and

transmitting, based on the predicted value, a report suspension message to the base station, the report suspension message indicating that the UE is not reporting the report parameter in the CSI report in the one or more future reporting occasions.

2. The method of claim 1 , further comprising:

determining a measurement value associated with the report parameter;

determining an actual value of the report parameter based on the measurement value;

determining that a difference between the predicted value and the actual value is greater than a threshold value; and

resuming provision of the report parameter in the CSI report based on the difference being greater than the threshold value.

3. The method of claim 2 , further comprising transmitting, subsequently to the report suspension message, a report resumption message to the base station based on the actual value being greater than the threshold value, the report resumption message indicating that the UE is reporting the report parameter in at least a portion of the one or more future reporting occasions.

4. The method of claim 1 , wherein determining the predicted value of the report parameter comprises determining the predicted value of the report parameter based at least in part on providing the plurality of historic measurements as input to a machine learning model.

5. The method of claim 1 , wherein determining the predicted value of the report parameter comprises determining the predicted value of the report parameter based at least in part on providing the plurality of historic measurements as input to a recurrent neural network.

6. The method of claim 1 , wherein determining the predicted value of the report parameter comprises determining the predicted value of the report parameter based on a mobility state of the UE.
