Present disclosure generally relates to wireless communication and particularly relates to system and method for dynamic multicarrier allocation to NB-IoT devices. Method includes receiving from PMS, PRB utilization data for a time slot or data packets, and comparing PRB utilization duration in received PRB utilization data with pre-defined threshold PRB utilization duration. Requesting via NB-IoT eNB, cumulative NACK percentage report corresponding to ARFCN/PRB, if PRB utilization duration is less than a pre-defined threshold. Method includes selecting, ARFCN/PRB for a time slot, based on PRB utilization data and cumulative NACK percentage report and pre-defined value. Method includes establishing connection between NB-IoT enabled devices and NB-IoT eNB, upon transmitting via LTE eNB, information associated with selected ARFCN/PRB for time slot, to NB-IoT eNB. Method includes notifying LTE eNB, representative of utilization of ARFCN/PRB as non-anchor carrier. Method includes allocating ARFCN/PRB as non-anchor carrier to schedule NB-IoT enabled devices for data transfer in selected time slot.
