1. A method by a wireless device for restricting channel state information, CSI, measurement comprises:
receiving, from a network node, information identifying a first subset of channel state information-reference signal, CSI-RS, resources comprising one or more parameters identifying a first subset of physical resource blocks (PRBs) to be used in performing CSI measurements, the first subset of CSI-RS resources being associated with a first portion of a frequency band that is less than all of the frequency band, wherein the information received from the network node further identifies a first CSI reporting type of a plurality of CSI reporting types for reporting the CSI associated with the first subset of CSI-RS resources; and
performing CSI measurements in the first subset of CSI-RS resources being associated with the first portion of the frequency band.
