CSI Prediction
A technique that uses historical CSI sequences to infer channel states at future time steps. It aims to reduce pilot measurement and feedback overhead and to provide forward-looking scheduling information to the transmitter. Its difficulty lies in the time-varying nature and scenario dependence of wireless channels.
Timeline (last 90 days)
CSI prediction is the use of historical CSI sequences to infer the channel state at several future time instants, which can reduce pilot density or feedback frequency.
Most existing deep learning CSI prediction schemes solidify channel knowledge in model parameters, so that scenario switching requires retraining or extensive fine-tuning.
