1. A method in a new radio, NR, base station for determining Channel State Information Interference Measurement resources, CSI-IM resources, for interference measurement, the NR base station spectrum sharing with a Long Term Evolution, LTE, base station, the method comprising:
determining a CSI-IM pattern for a CSI-IM resource, wherein the CSI-IM pattern is defined by one or more first OFDM symbols and a first frequency shift; and
transmitting a Channel State Information Reference Signal, CSI-RS, according to a CSI-RS pattern, the CSI-RS pattern being defined by a second OFDM symbol and a second frequency shift, the first frequency shift and the second frequency shift do not overlap and the one or more first OFDM symbols overlap with the second OFDM symbol.
