Methods, systems, and devices for wireless communication are described. A user equipment (UE) may detect and report blockage conditions based on measuring signal strengths of reference signals. A UE may determine a slew rate for the signal strength, corresponding to a rate of change of a signal strength parameter (e.g., a reference signal received power (RSRP) or a received signal strength indicator (RSSI)) with respect to time, and report the slew rate to a base station to indicate signal strength degradation (e.g., due to a blockage). In some examples, the UE may define multiple slew rates associated with different rates of change of the signal strength parameter with respect to time. When the UE crosses a level of slew rate, the UE may indicate this to the base station to initiate mitigation procedures. In some examples, the techniques described herein may be extended to reporting slew rates for multiple beams.
