Abstract: A system and method identifying at least one aggressor cell. The method comprises transmitting at least one subframe from at least one base station of a first set of base stations to a second set of base stations, wherein the at least one subframe further comprises of at least one downlink subframe, at least uplink subframe and at least one special subframe. The second set of base stations decodes the at least one received subframe, and maps each of the at least one received downlink subframe, at least one received uplink subframe and at least one received special subframe of the at least one received subframe to at least one expected subframe. Lastly, at least one aggressor cell is determined based on a mismatch of the at least one received subframe and the at least one expected subframe.

Abstract: System and method for synchronizing at least one small cell with at least one macro cell in a heterogeneous network. The method comprises the at least one small cell triggering an NB-IoT modem for a clock reference signal. The NB-IoT modem detects a first synchronization signal and a second synchronization signal, the first synchronization signal and the second synchronization signal being transmitted by at least one NB-IoT cell connected to the at least one macro cell. The NB-IoT modem synchronizes the at least one small cell with the at least one macro cell based on at least one of the first synchronization signal and the second synchronization signal.

Abstract: A system and method, for identification of the user equipment with IMS PDN connectivity issues, and proactively recovering the PDN connectivity for said user equipment is disclosed. The disclosure provides triggering the System initiated detach with re-attach required request, to user equipment by checking the current IMS PDN state of said VoLTE user equipment to recover the IMS PDN connectivity. The present disclosure provides a novel automatic method for maintaining IMS PDN connection providing continuous voice call connectivity and improving the overall connectivity and user experience of the wireless network.

Abstract: A system and method to provide identification of the Tune Away in DSDS device, wherein identification of such Tune Away in DSDS device and mitigation of such Tune Away is done by Aperiodic CQI, Hybrid Automatic Repeat Request (HARQ) and Pro-Active scheduling based on periodicity and duration of Tune Away to minimize HSI degradation in DSDS devices. This disclosure provides improved throughput for network subscriptions in multi-SIM, multi-RATs wireless devices by preventing downlink scheduling in Tune Away periods and minimize radio resource wastage occurring due to DSDS UEs as well as improving HSI performance in such UEs by preventing lower layer retransmissions and conserve radio resources that are wasted in carrying those retransmissions earlier. The disclosure increases throughput performance for the data session in a DSDS device ecosystem and prevent substantial decline in average throughput experienced at DSDS UE.

Abstract: A system and method for mitigating at least one aggressor cell. The method comprises categorizing at least one user equipment connected to the at least one aggressor cell [102A, 102B, 102C, 102D] based on a position of the at least one user equipment within a coverage area of the at least one aggressor cell [102A, 102B, 102C, 102D]. The at least one user equipment positioned at the center of the coverage area of the at least one aggressor cell [102A, 102B, 102C, 102D] is scheduled for downlink transmission in at least one special subframe. The at least one aggressor cell [102A, 102B, 102C, 102D] reduces transmission power of the at least one special subframe by a pre-determined value and transmits the at least one special subframe to a first set of base stations [102E, 102F].
