1. A method in a user equipment, UE, for reporting channel state information, CSI, to a network, the method comprising:
determining a number of subbands of a bandwidth part, BWP, to report CSI;
determining a CSI computation time including a CSI computation delay requirement;
performing CSI estimation for a plurality of the number of subbands based on the CSI computation time; and
reporting the CSI report for at least one of the number of subbands, determining the CSI computation time comprising determining the CSI computation delay requirement, and determining the CSI computation delay comprising applying CSI computation delay requirement Z1 and their primes Z′1 for wideband frequency granularity to subband frequency granularity.
