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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods, apparatus and systems for handling additional power backoff","description":"Methods, apparatus and systems are described for a wireless transmit/receive unit (WTRU) to manage its transmission power.
