In accordance with an embodiment, the DSP 206 may be further configured to initiate an uplink communication by application of beam reciprocity to the communicated beam of RF signals in the second NR carrier. The DSP 206 may be further configured to acquire Time Division Duplex (TDD) configuration information from the FWA UE 304 over the established short-range wireless communication link 116, and accordingly start TDD switching in the NR frequency in the 5G NR network 114.

FIGS. 4A, 4B, and 4C collectively, depict a flow chart that illustrates an exemplary method for low-power and low-latency NSA initial access to 5G NR carrier, in accordance with an embodiment of the disclosure. FIGS. 4A, 4B, and 4C are explained in conjunction with elements from FIGS. 1, 2, and 3. With reference to FIGS. 4A to 4C, there is shown a flow chart 400 comprising exemplary operations 402 through 436 by the communication device 102.

At 402, beam acquisition may be initiated in receive-only mode at the communication device 102. The front-end RF circuitry 214 may be set to the receive-only mode, in which the Tx phased array 218 may be deactivated and thus a further communication of input RF signals is deactivated.

At 404, the short-range wireless communication link 116 (e.g., Bluetooth, Wi-Fi, Li-Fi, and the like) may be established with the FWA UE 104A (or the mobile UE 104B) that is in a specified proximal range of the communication device 404.
