Technology for a user equipment (UE) operable to decode a channel state information reference signal (CSI-RS) resource received from a Next Generation NodeB (gNB) is disclosed. The UE can decode a downlink control channel signal received from the gNB in a first bandwidth part. The downlink control channel signal may include an index of a second bandwidth part, and an indication of a CSI-RS transmission in the second bandwidth part having the index. The UE can switch from the first bandwidth part to the second bandwidth part. The UE can decode the CSI-RS transmission received from the gNB in the second bandwidth part.
