Title: SYSTEM AND METHOD FOR FLEXIBLE CHANNEL STATE INFORMATION-REFERENCE SIGNAL TRANSMISSION
Abstract:
System and method for flexible channel state information-reference signal transmission A method by a wireless device is provided for restricting channel state information (CSI) measurement. The method includes receiving, from a network node, information identifying a first subset of channel state information-reference signal (CSI-RS) resources to be used in performing CSI measurements. The first subset of CSI-RS resources are associated with a first portion of a frequency band that is less than all of the frequency band. CSI measurements are performed in the first subset of CSI-RS resources that are associated with the first portion of the frequency band.
