Throughput Enhancement by Location-Based Power Adjustment in 5G and 6G
The transmission power level is an important parameter in 5G/6G networking because it affects the failure rate if too low, background interference if too high, and battery life of user devices if retransmissions are required, among many other aspects of communications. Disclosed is an AI (artificial intelligence) model to recommend a transmission power level, based on inputs including: current network parameters such as the current throughput or message failure rate or average delay per message; parameters of the planned parameters such as the length and priority of the planned message; and environmental parameters such as the current noise or background interference level. In addition, the AI model adjusts for the distance between the transmitter and receiver, plus any known obscurations, among other inputs. The AI model then provides a recommended power setting for each message, adjusted to provide reliable reception but without wasting excess power.
