SPECIFIC ABSORPTION RATE BACKOFF IN POWER HEADROOM REPORT
First Claim
1. A method of wireless communication, comprising:
- receiving an uplink transmission grant from a serving base station;
determining a maximum power reduction for uplink transmissions at a mobile device;
determining a specific absorption rate (SAR)-related power reduction;
comparing the maximum power reduction with the SAR-related power reduction; and
adjusting transmission power according to the SAR-related power reduction in response to the SAR-related power reduction exceeding the maximum power reduction.

Abstract
Uplink transmission power adjustment is provided by a mobile device receiving an uplink transmission grant from a serving base station. The mobile device determines a maximum power reduction for uplink transmissions and a SAR-related power reduction. The mobile device compares these values and adjusts transmission power according to the SAR-related power reduction in response to the SAR-related power reduction exceeding the maximum power reduction. A power headroom report is generated when the determined SAR-related power reduction exceeds a previous SAR-related power reduction. This power headroom report is transmitted from the mobile device to the serving base station under various conditions.
