1. A user equipment (UE), comprising:
a transceiver;
a memory; and
a processor,
wherein the transceiver, the memory, and/or the processor are configured to:
receive, from a network node, a plurality of tracking resource sets comprising a first tracking resource set and a second tracking resource set;
process the first tracking resource set and the second tracking resource set to determine one or more positioning related quantities; and
estimate a position of the UE based on the one or more positioning related quantities and/or report the one or more positioning related quantities to a network entity,
wherein the first tracking resource set comprises a first plurality of reference signal resources, and the second tracking resource set comprises a second plurality of reference signal resources,
wherein the first plurality of reference signal resources and the second plurality of reference signal resources are mapped in a frequency domain into different subcarriers which are staggered in a same bandwidth or resource blocks relative to each other within a same subframe,
wherein the first plurality of reference signal resources of the first tracking resource set are transmitted from a same antenna port of the network node or are quasi-co-located (QCL′d) reference signals with the second plurality of reference signal resources of the second tracking resource set, and
wherein subcarrier offsets of the plurality of reference signal resources of the respective tracking resource set are different from subcarrier offsets of the plurality of reference signal resources of all other tracking resource sets such that each subcarrier contains reference signal resources of no more than one of the plurality of tracking resource sets.
