1. A method for a wireless device, WD, configured to communicate with a network node, the method comprising:
receiving a configuration of a channel state information, CSI, reference signal resource set from the network node, the CSI reference signal resource set comprising a plurality of single symbol and single antenna port reference signal resources in at least one slot, the received configuration comprising an indicator indicating that the single antenna port of all of the plurality of reference signal resources in the set are the same;
receiving from the network node reference signal resources in accordance with the configuration of the CSI reference signal resource set; and
based on the indicator, using the received reference signal resources as a set of tracking reference signals.
