Within the set of ports for particular CSI-RS resource, one or more port groups may further be configured. Each port group identifies a group of ports associated with a channel. In some examples, a port group identifies the ports on which CSI may be measured. Other ports within the set of ports that are outside the port group may be utilized for interference measurement.
