Channel state information prediction in a wireless network

A method performed by a network apparatus in a wireless network, the method comprising:

• receiving, from a User Equipment (UE), a UE capability information and the plurality of channel parameters;
• and
• determining a length of an observation window (OW) and a length of a prediction window (PW) based on the UE capability information and the plurality of channel parameters,
• wherein the UE capability information includes candidate value of a N4 parameter indicating a length of discrete fourier transform (DFT) vector.

A User Equipment (UE) in a wireless network, the UE comprising:

• a memory;
• and
• a controller coupled to the memory and configured to:
• measure a channel in an observation window (OW),
• determine a spectral estimation of the channel in the OW,
• determine a plurality of channel parameters based on the spectral estimation of the channel in the OW, and
• transmit, to a network apparatus, a UE capability information and the plurality of channel parameters,
• wherein the UE capability information includes candidate value of a N4 parameter indicating a length of discrete fourier transform (DFT) vector.
