lte user equipment (ue) receiver performance has significant impact to cellular radio network coverage and capacity. it determines the maximum data throughput across the air interface between the lte base station (enb, evolved node b) and the mobile network subscriber ue, thus it determines the total capacity across the air interface. therefore, it is one of the most important measurements to verify the actual receiver performance of individual devices, and a key metric to compare different devices, in particular.this paper shall give an introduction to receiver performance measurements and discusses the measurement metrics as well as the challenges of over the air (ota) measurements.
