Title
(EN) Minimization drive test with reduced wireless device memory usage
Abstract
(EN)

A mobile wireless communication device efficiently uses memory when performing a minimization drive test (MDT) by storing less than all of the MDT measurements. The mobile wireless communication device receives a control signal comprising MDT configuration parameters indicating at least a measurement interval. When executing the MDT, the mobile wireless communication device measures a signal characteristic of measurement signals in accordance with the MDT configuration parameters to generate a number of measurements for a measurement period. Rather than storing all of the measurements, only a number of log values corresponding to the measurements are stored in memory, where the number of log values is less than the number of measurement values.
