Title:
CONFIGURATIONS FOR OMITTING CHANNEL STATE INFORMATION
Document Type and Number:
WIPO Patent Application WO/2021/056376
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to use one or more channel state information (CSI) omission configurations for omitting portions of a CSI report. For example, a UE may receive a trigger to report CSI, and the UE may identify that a payload of the CSI report exceeds a capacity of resources for transmitting the report. As such, the UE may determine to use one or more CSI omission configurations, where each CSI omission configuration may correspond to dropping different portions of the CSI report. The selection of the CSI omission configuration to use may be based on a set of parameters associated with CSI reporting. In some cases, the UE selects the CSI omission configuration based on an explicit indication from the base station. Additionally or alternatively, the UE may implicitly determine the CSI omission configuration based on the parameters.
