Techniques are provided for adaptively changing a periodicity of measuring signal characteristics for a UE in a relatively high speed environment based on one or more signal characteristics being outside of a threshold. Periodicity of measuring signal characteristics may be made directly by changing an interval at which measurements are taken. In certain examples, periodicity of measuring signal characteristics may be made indirectly by changing the length of a discontinuous reception (DRX) cycle. Some techniques provide one or more radio link monitoring (RLM) parameters may be modified based on a determination that a UE is in a high speed environment or measured signal characteristics are outside of a threshold.
