Various embodiments of the disclosure may provide a system for low-latency initial access to non-standalone 5G NR network. The system may include the communication device 102 (FIG. 1) that comprises the front-end RF circuitry 214 (FIG. 2) and the DSP 206 (FIG. 2) that may be communicatively coupled to the front-end RF circuitry 214. The DSP 206 may be configured to establish a short-range wireless communication link (e.g. the short-range wireless communication link 116) with the FWA UE 104A (or the mobile UE 104B) (FIG. 1) that is in a specified proximal range of the communication device. The DSP 206 may be further configured to determine that the FWA UE 104A (or the mobile UE 104B) is in a RRC connected state over a LTE network, based on the established short-range wireless communication link. The DSP 206 may be further configured to detect whether a first NR carrier is assigned to the FWA UE independent of use of the communication device 102 for the NR carrier assignment, based on the established short-range wireless communication link. The DSP 206 may be further configured to determine that a carrier measurement for NR is established at the FWA UE 104A (or the mobile UE 104B) by a LTE-enabled base station (such as the first base station 106) in the RRC connected state, based on the established short-range wireless communication link and at least one of an absence of the assignment of the first NR carrier to the FWA UE 104A (or the mobile UE 104B) or a received signal characteristic associated with the assigned first NR carrier is less than a signal quality threshold. The DSP 206 may be further configured to control an assignment of a second NR carrier, having the received signal characteristic greater than the signal quality threshold, to the FWA UE 104A (or the mobile UE 104B) for non-standalone initial access to a beam of RF data signals in the second NR carrier at the FWA UE 104A (or the mobile UE 104B), where the beam of RF data signals in the second NR carrier may be communicated (or relayed), by the communication device 104, from a NR-enabled base station (such as the second base station 108) to the FWA UE 104A (or the mobile UE 104B) for the assignment of the second NR carrier at the FWA UE 104A (or the mobile UE 104B) based on at least the determination that the carrier measurement for NR is established at the FWA UE 104A (or the mobile UE 104B).
