Question: In E-UTRA, when applying Layer 3 filtering to measurement results according to 3GPP specifications, how is the filter coefficient 'a' determined for Non-Radio Access Technology (NR) measurements?
Option 1: a = 1/2(k/4) where k is a fixed value defined in the UE's configuration.
Option 2: a = 1/2(ki/4) where ki is the filterCoefficient for the corresponding measurement quantity of the i:th QuantityConfigNR, indicated by quantityConfigSet in MeasObjectNR.
Option 3: a = k/2 where k is derived from the UE's current cell ID.
Option 4: a is a constant value (e.g., 0.5) for all NR measurements.
Explanation: For Non-Radio Access Technology (NR) measurements, the filter coefficient 'a' used in Layer 3 filtering is specifically determined based on the filterCoefficient (ki) of the i:th QuantityConfigNR, as indicated by quantityConfigSet in MeasObjectNR. This approach allows for tailored filtering based on the specific measurement quantity being evaluated, preserving the time characteristics of the filter across different input rates.
