1. A method of performing measurement at a user equipment (UE) in a wireless communication system, the method comprising:

  • receiving measurement configuration information including a plurality of measurement objects and a s-measure value related to a neighbor cell measurement;

    measuring activated serving cells indicated by the plurality of measurement objects to obtain a plurality of measurement results, the activated serving cells including a s-measure associated serving cell and at least one s-measure non-associated serving cell;

    comparing the s-measure value only with a first measured value from the plurality of measurement results, the first measured value being related to the s-measure associated serving cell;

    when the first measured value is lower than the s-measure value, measuring the s-measure associated serving cell and the at least one s-measure non-associated serving cell;

    comparing a measurement of the at least one s-measure non-associated serving cell from with a threshold for a reporting event configured in the UE; and

    transmitting a measurement report of the at least one s-measure non-associated serving cell when the measurement of the at least one s-measure non-associated serving cell satisfies the threshold for the reporting event,wherein the s-measure value is dedicated to the UE and received via radio resource control (RRC) signaling.
