1. A radiation power level control method for a wireless user equipment (UE) device, the method comprising:
- determining that a current transmission event involving the wireless UE device is commenced outside a time duration from a last transmission event; and
responsive to the determining, disregarding a power data history associated with the wireless UE device in computing a Specific Absorption Rate (SAR) value for the wireless UE device during the current transmission event.

Abstract
A radiation power level control scheme for a wireless user equipment (UE) device. In one embodiment, a method comprises determining that a current transmission event involving the wireless UE device is commenced outside a time duration from a last transmission event. If so, responsive to the determining, the method involves disregarding or resetting a power data history associated with the wireless UE device in computing a Specific Absorption Rate (SAR) value for the wireless UE device during the current transmission event. Otherwise, at least a portion of the power data history may be used in computing the SAR values.

9. A non-transitory computer-readable medium containing instructions stored thereon which, when executed by one or more processors of a wireless user equipment (UE) device disposed in a network environment, facilitate radiation power level control of the wireless UE device, the nonvolatile storage computer-readable medium comprising:
-
program instructions for determining that a current transmission event involving the wireless UE device is commenced outside a time duration from a last transmission event; and program instructions, responsive to the determining, for disregarding a power data history associated with the wireless UE device in computing a Specific Absorption Rate (SAR) value for the wireless UE device during the current transmission event. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A network node comprising:
-
a component for tracking and maintaining a history of power data for a wireless UE device served by the network node, wherein the power data comprises data tracked over a time window relative to one or more variables on a per transmission event basis for the wireless UE device; a Specific Absorption Rate (SAR) determining module for determining a SAR value for the wireless UE device during a current transmission event involving the wireless UE device, wherein the SAR determining module is configured to disregard the history of power data if the current transmission event occurred outside a time duration from a last transmission event involving the wireless UE device; and an adjustment and notification module configured to facilitate at least one of the following if the SAR value exceeds a SAR threshold of the wireless UE device;
(i) providing a notification to a user of the wireless UE device, (ii) reducing a transmission power level of the wireless UE device during the current transmission event, (iii) changing a modulation and coding scheme (MCS) used in respect of the current transmission event, (iv) terminating the current transmission event, and (v) delaying the current transmission event. - View Dependent Claims (18, 19, 20)
