Abstract: According to various embodiments, a method performed by a user equipment (UE) in a wireless communication system, comprising: receiving, from a base station, a channel state information (CSI)-reference signal (RS) during an observation window (OW); predicting at least one first type CSI report during the OW; transmitting, to the base station, the at least one predicted first type CSI report during the OW and a second type CSI report at an end of the OW based on the received CSI-RS. The linear prediction based method is used for CSI-feedback in the wireless communication network, in situations where high/medium velocity feedback (i.e., Doppler) is present. The method can be used to enable a CSI-Type 2 codebook feedback feature during a mobility scenario.
