Wireless communication transmit power control based on hybrid automatic repeat request (HARQ) block error rate (BLER)

A Fifth Generation New Radio (5GNR)/Long Term Evolution (LTE) User Equipment (UE) to control power consumption, the 5GNR/LTE UE comprising:

• control circuitry configured to select an initial 5GNR transmit power and an initial LTE transmit power, signal the initial 5GNR transmit power to a 5GNR radio, and signal the initial LTE transmit power to an LTE radio;
• the 5GNR radio configured to transmit initial 5GNR signals at the initial 5GNR transmit power;
• the LTE radio configured to transmit initial LTE signals at the initial LTE transmit power;
• the control circuitry configured to average Uplink (UL) Hybrid Automatic Repeat Request (HARQ) Block Error Rate (BLER) for an error sampling period and compare the average UL HARQ BLER for the error sampling period to an error threshold;
• when the average UL HARQ BLER exceeds the error threshold, the control circuitry configured to select a lower 5GNR transmit power and a higher LTE transmit power, signal the lower 5GNR transmit power to the 5GNR radio, and signal the higher LTE transmit power to the LTE radio;
• and
• the LTE radio configured to transmit subsequent LTE signals at the higher LTE transmit power.
