1. A method comprising:
- receiving a radio-frequency (RF) signal via a configurable front-end of a wireless device;
determining a power metric for the wireless device, wherein the power metric indicates an amount of available power to the wireless device;
determining a link quality metric based at least in part on a signal from a circuit to harvest power from the received RF signal;
determining a configuration of the configurable front-end based at least in part on the power metric and the link quality metric; and
configuring the configurable front-end based at least in part on the determined configuration.

Abstract
Method and apparatus for controlling the power consumption of a wireless device are provided. A wireless device may include a configurable radio frequency (RF) front-end that may be configured to use fewer hardware stages and/or processing steps to reduce power consumption based at least in part on a signal quality, detected interference, or system information associated with a received RF signal. In some implementations, the configurable RF front-end may be configured to consume less power while receiving strong RF signals and configured to consume more power while receiving weak RF signals.

11. A wireless device comprising:
-
a configurable front-end configured to receive an RF signal; a controller; and a memory configured to store instructions that, when executed by the controller, cause the wireless device to; determine a power metric, wherein the power metric indicates an amount of available power to the wireless device; determine a link quality metric based at least in part on a signal from a circuit to harvest power from the received RF signal; determine a configuration of the configurable front-end based at least in part on the power metric and the link quality metric; and configure the configurable front-end based at least in part on the determined configuration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method comprising:
-
receiving a radio-frequency (RF) signal via a configurable front-end of a wireless device; determining an operating metric based at least in part on a signal indicating an amount of power harvested from the received RF signal; configuring the configurable front-end to increase power consumption in response to determining that the operating metric is less than a first threshold; and configuring the configurable front-end to decrease power consumption in response to determining that the operating metric is greater than a second threshold. - View Dependent Claims (22, 23, 24, 25, 26)
