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.

Description

[0001] Cross-reference related application

[0002] The present application claims the rights of the topic submitted by "Specific ABSorption Rate Backoff in Power Headroom Report", which is described on November 4, 2010, which is clearly explicitly Ensemble this article. Technical field

[0003] Aspects of the present application, generally relate to wireless communication systems, and more particularly to power margin reporting in wireless networks. Background technique

[0004] Wireless communication networks are widely deployed to provide various communication services, such as voice, video, packet data, messaging, broadcasting, etc. These wireless networks can be multi-access networks that can support multiple users by sharing available network resources. An example of such a network is a Universal Land Wireless Access Network (UTRAN). UTRAN is a wireless access network (RAN) that is defined as part of the General Mobile Telecommunications System (UMTS), which is a third gener...
