Application: Modem performance enhancement via smart transmission power distribution (Patent ID: US20230379844A1)

The patent filed by MediaTek Inc. describes a power-adjusting method for uplink transmission in user equipment (UE). The method involves increasing transmission power in response to the UE transmitting a first packet carrying a specific message to a network node. Additionally, the method includes decreasing transmission power when the UE transmits a second packet carrying normal data to the network node, with the average of the transmission powers meeting a power requirement based on time averaged power density or specific absorption rate.

The patent further details the specific messages that trigger the power adjustments, such as Transmission Control Protocol (TCP) ACK, TCP NACK, Radio Link Control (RLC) Status Protocol Data Unit (PDU), or high sensitivity traffic with latency. The UE described in the patent includes a radio frequency signal processing device and a processor that adjusts transmission power based on the type of packet being transmitted. The computer-readable medium stores instructions for the UE to execute the power-adjusting steps, ensuring efficient uplink transmission based on the specific message being sent.
