HeterCSI

Gold definitionUpdated Apr 2, 2026

Definition

HeterCSI is a channel-adaptive pretraining framework for wireless foundation models, designed to overcome the dual heterogeneity of Channel State Information (CSI) across scale and scenario. It improves generalization and training efficiency by managing gradient dynamics in heterogeneous CSI pretraining.
