In this regard, a WDS is configured to determine both the separate downlink and uplink propagation delays between a central unit and a plurality of remote units. It is not presumed that the downlink propagation delay and the uplink propagation delay in the WDS are symmetric to provide a more accurate determination of propagation delay. Therefore, it is possible to determine the downlink and uplink propagation delays with improved accuracy, thus enabling more precise location identification in the WDS.

The UE may modulate and code information for uplink transmissions using the identified MCS table.

Each path identifier indicates a route that the respective flow takes in the physical network to reach the respective destination tunnel endpoint. The path identifier and the flow identifier of the respective flows are then transmitted to a controller of the virtual network.
