Samsung patents phone method to boost signal power during safety limits

Samsung has been granted a patent for a method that allows a phone to transmit certain radio signals at higher power levels than its standard safety limit. The device identifies when a safety event, such as a specific absorption rate (SAR) limit, is active and then boosts the power for specific message types that require it, while keeping other messages within the reduced limit.

Why it mattersThis filing details a technical adjustment to how phones manage their radio power during safety checks, which could help maintain connection stability without exceeding long-term exposure limits.

In the filing’s own words

An electronic device is provided. The electronic device includes a processor and an RF device, the processor configured to identify transmission powers respectively corresponding to a plurality of messages, identify the maximum output power of the electronic device on the basis of its state, control the RF device to, when at least one first transmission power corresponding to at least one first message of the plurality of messages is less than the maximum output power, provide a first RF signal having the maximum output power for transmission of the at least one first message, and control the RF device to, when at least one second transmission power corresponding to at least one second message of the plurality of messages is less than the maximum output power, provide a second RF signal having a power greater than the maximum output power for transmission of the at least one second message.

What exactly they claim (claim 1)

1. An electronic device, comprising: at least one radio frequency (RF) device, memory storing instructions; and at least one processor communicatively coupled to the at least one RF device and the memory, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to: identify an allowable output power of the electronic device that is reduced from a maximum output power of the electronic device according to an occurrence of a specific absorption rate (SAR) event, identify message types to be transmitted among a first type of messages type and a second types of messages, control, in case that a first transmission power determined for transmitting the first type of messages is larger than the allowable output power, the at least one RF device to provide a first RF signal having the allowable output power to transmit at least one message of the first type while the SAR event is occurring, and control, in case that a second transmission power determined for transmitting the second type of messages is larger than the allowable output power, the at least one RF device to provide a second RF signal having a power larger than the allowable output power, to transmit at least one message of the second type while the SAR event is occurring.
