In user equipments (UEs) with multiple radios, interference between those radios may be reduced by monitoring radio performance and adjusting aggressor transmit power levels to ensure victim and aggressor performance stay within desired operational levels. Various factors may determine when a reduced power approach is desired. Such factors may include aggressor transmit power, received signal strength indicator, victim error rate, throughput loss, coverage impact, etc. Various methods of reducing transmit power may be used. For example, for Long Term Evolution communications, a power headroom report may be altered to adjust a modulation coding scheme and bandwidth allocated for a particular UE. For Bluetooth communications a power control mechanism may be overridden to ensure a device stays within a desired transmit power. A power reduction loop may be employed to monitor a device's transmit power.
