Method and device to minimize interference in a converged LMR/LTE communication device

A converged LMR/LTE communications device for minimizing interference when operating in a land mobile radio (LMR) narrowband communication system and a long term evolution (LTE) broadband communication system, the converged LMR/LTE communications device comprising:

• a processor that performs:
• determining a first LMR received signal strength indicator (RSSI) at the converged LMR/LTE communications device;
• determining a first LTE Reference Symbol Receive Power (RSRP) at the converged LMR/LTE communications device;
• determining whether an intersection of the first LMR RSSI and the first LTE RSRP falls within an interference range on a predetermined graph, the predetermined graph based upon an LMR frequency band and an LTE frequency band that the converged LMR/LTE communications device is currently utilizing;
• and
• decreasing bit rate for LTE transmissions for the converged LMR/LTE communications device responsive to determining that the intersection of the first LMR RSSI and the first LTE RSRP is within the interference range.
