Abstract: A method of downlink channel state information (DL CSI) computation and reporting is proposed to support high velocity in new radio (NR) systems. In a first novel aspect, two CSI reference slots are defined. CSI reference slot for CSI measurement is defined for determining which CSI-RS/SSB occasion(s) is used for computing CSI. CSI reference slot for CSI computation is defined for determining the slot where UE assumes the CSI computation should be based upon the channel at that time onwards. In a second novel aspect, UE can be configured with a CSI computation period consisting of one or N slots and can be divided into multiple sub-periods without overlap. UE can be configured to compute and report wideband CSI and subband CSI for the whole CSI computation period and/or for each sub-period.
