Abstract
Methods, apparatus and systems are described for a wireless transmit/receive unit (WTRU) to manage its transmission power. A power headroom report (PHR) may be triggered based on changes to backoff or the impacts of backoff. Additional backoff may be used to calculate a maximum output power of the WTRU and may be indicated by a domination indicator to network resources. The WTRU may be configured to eliminate triggers caused by virtual PHRs. Furthermore, the WTRU may be configured to respond to rapid changes to backoff.
