Claim 11:
12. One or more non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed by at least one computing device, cause the computing device to perform operations for dynamically adjusting a 4G LTE reference signal power level to match a 5G NR coverage footprint to avoid voice over 4G fallback failures for 5G subscribers, the operations comprising:
receiving an indication, at a gNodeB, that user equipment (UE) attempting to transition to 4G LTE experienced a voice call setup failure at an eNodeB;
determining the UE was instructed by the gNodeB to go through release with redirect to the eNodeB;
based on the voice call setup failure occurring within a predetermined time period, communicating, by the gNodeB, to the eNodeB to dynamically adjust a 4G LTE reference signal power level.
