Method and Apparatus for Adjusting Layer 3 Filter Coefficients

An apparatus for use in a user equipment (UE) to adjust a layer 3 (L3) filter coefficient, the apparatus comprising:

• at least one processor;
• and at least one memory including computer program code;
• the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to:
• initialize 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;
• adjust 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
• apply the adjusted primary filter coefficient to measurements of one or more cells in an active cell set.

A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon, which, when executed by a processing system, cause the processing system to carry out a method comprising the steps of:

• 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
• adjusting the primary filter coefficient by 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.
