Claim 19:
20. A system 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 system comprising:
user equipment (UE) that receives instructions from a gNodeB to go through release with redirect to an eNodeB, wherein the UE or the gNode B lacks Voice over New Radio (VoNR) support;
the gNodeB that receives an indication that the UE attempting to transition to 4G LTE experienced a voice call setup failure at the eNodeB; and
the eNodeB that receives instructions from the gNodeB to dynamically adjust a 4G LTE reference signal power level based on the voice call setup failure occurring within a predetermined time period.
