The UE may monitor the radio link and may determine whether the radio link can support a lowest acceptable link quality according to a hysteresis-based comparison that uses threshold values to determine error rates associated with a physical control channel. The UE may also identify itself to the network as a link-budget-limited device, and the network may enable special link-budget enhancing features for the UE, including boosting the power of the resource elements (REs) carrying physical channel signaling/data to the UE. The UE may detect the presence of power boost and may estimate/determine the power boost level. The UE may modify the threshold values based on the power boost detection and/or results of the power boost level estimation/determination, and may use the modified threshold values for determining radio link quality during radio link monitoring."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio link monitoring for link-budget-limited devices","description":"A link-budget-limited wireless communication device (UE) may implement improved radio link monitoring procedures for enhancing the link-budget of the UE.
