1. A network node, comprising:
one or more transceivers;
one or more memory components; and
one or more processors communicatively coupled to the one or more transceivers and the one or more memory components, the one or more processors configured to:
transmit, via the one or more transceivers, a first measurement signal;
receive, via the one or more transceivers, a first response signal, the first response signal corresponding to the first measurement signal;
transmit, to a user equipment (UE) via the one or more transceivers, a second measurement signal, the first and second measurement signals being on different frequencies, delivered via different radio access technologies (RATs), or both;
receive, from the UE via the one or more transceivers, a second response signal, the second response signal corresponding to the second measurement signal; and
determine a first roundtrip time (RTT) between the UE and the network node based on the second measurement signal, the second response signal, and a first network node group delay (GD), the first network node GD determined based on the first measurement signal and the first response signal.
