METHOD AND APPARATUS FOR POWER AUTOSCALING IN A RESOURCE-CONSTRAINED NETWORK
An electronic device may adaptively manage power consumption associated with transmission and/or reception of signals by the electronic device, wherein the adaptive power management may comprise adjusting transmit power and/or one or more power-related thresholds used during transmission or reception operations in the electronic device. Adjustments to the transmit power and/or the one or more power-related thresholds may be determined based on comparison between power measurement associated with signals received by said electronic device with original transmit power for the signals. The reception power measurement may be determined based on detected received signal strength indication (RSSI). The original transmit power may be determined based on signal transmission information embedded in at least one frame carried via said signals. The original transmission power may be embedded as an equivalent isotropic radiated power (EIRP) value.
