In accordance with an embodiment, the DSP 206 may be further configured to determine whether the LTE-enabled base station established the carrier measurement for NR for a new carrier that is the second NR carrier that has a highest received signal strength indicator (RSSI) at the FWA UE 104A (or the mobile UE 104B) from among a plurality of RSSIs associated with a plurality of different beams of RF signals received at the communication device 102, based on the acquired information of the one or more SSBs. The second NR carrier is assigned to the FWA UE based on the established carrier measurement for NR for the second NR carrier.

The DSP 206 may be further configured to validate the beam acquisition at the FWA UE 104A (or the mobile UE 104B) for the non-standalone access to the beam of RF signals in the NR frequency as successful based on a match of the acquired PCI of the NR-enabled base station and the PCI associated with the beam of RF signals that has the highest received signal strength. The DSP 206 may be further configured to initiate an uplink communication (e.g., from the FWA UE 104A (or the mobile UE 104B) to the second base station 108) by application of beam reciprocity to the communicated beam of RF signals in the NR frequency.
