A method for a user equipment (UE) to adjust a layer 3 (L3) filter coefficient, comprises initializing a first filter coefficient of a first filter and a second filter coefficient of a second filter based on a primary filter coefficient of a primary filter, the primary filter coefficient being received from an associated wireless network entity; adjusting the primary filter coefficient by one of: setting the primary filter coefficient to the first filter coefficient if a first difference between a measurement result of the primary filter and a first measurement result of the first filter is less than a first coefficient threshold and setting the primary filter coefficient to the second filter coefficient if a second difference between the measurement result of the primary filter and a second measurement result of the second filter is less than a second coefficient threshold; and applying the adjusted primary filter coefficient to measurements of one or more cells in an active cell set. The first and second coefficient thresholds may be based upon empirical offline data relating to signal qualities, traffic conditions, applied primary filter coefficients, UE performance data such as call drop numbers and rates, and mobility data etc.. May be used when measuring the signal quality of cells in a UMTS system (eg RSCP, Ec/Io). |
