REGULATORY LIMIT COMPLIANT PACKET PRIORITY-BASED ADAPTIVE TRANSMIT POWER CONTROLLER

Abrégé

A wireless device includes one or more antennas coupled to a transmit (TX) chain. The TX chain is configured to generate output RF signals using baseband signals. The TX chain includes a TX power controller configured to classify a packet of the output RF signals into a priority category of a plurality of priority categories based on priority information within the packet. The TX power controller is further to determine a time average specific absorption rate (TAS) energy budget of the wireless device. The TAS energy budget is based on a pre-configured regulatory power limit (e.g., SAR transmit power limit) of the wireless device over a time interval. Transmission power for transmitting the packet is determined based on the priority category and the TAS energy budget. The packet is encoded for transmission via the one or more antennas using the determined transmission power.
