Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of operating a user equipment (UE) for CSI feedback is provided. The method comprises receiving configuration information for the CSI feedback from a base station (BS) and identifying a number of antenna ports for the CSI feedback. The method comprises, if the number of antenna ports is

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.
