adjust a parameter of the predetermined filter operation to reduce an influence of a measurement result with a high interference; and
perform mobility management of the electronic device based on a result of the filtering.

2. The electronic device of claim 1 , wherein the circuitry is further configured to:
judge whether an interference in the result of the measurement satisfies a predetermined condition; and
if the predetermined condition is satisfied, label the result of the measurement as a measurement result with high interference.

3. The electronic device of claim 2 , wherein the circuitry is further configured to:
generate a measurement report containing statistical information on the measurement result with high interference.

4. The electronic device of claim 2 , wherein the circuitry is further configured to:
evaluate whether to report the result of the filtering based on the measurement result with high interference.

5. The electronic device of claim 3 , wherein the circuitry is further configured to:
selectively report the result of the filtering and the statistical information on the measurement result with high interference to a base station according to an evaluation result.

6. The electronic device of claim 2 , wherein the circuitry is further configured to:
correct the measurement result with high interference to eliminate influence on the mobility management from the interference, and output the corrected measurement result.

7. The electronic device of claim 2 , wherein the circuitry is further configured to:
adjust relevant filtering parameters to reduce influence on the mobility management from the measurement result with high interference.

8. The electronic device of claim 1 , wherein the circuitry is further configured to:
reselect a cell in a case that the electronic device is in an idle state; and
report the result of the measurement in a case that the electronic device is in a connected state.

9. A method in a wireless communication system, comprising:
measuring a discovery reference signal of a target cell on an unlicensed frequency in a reference signal measurement timing configuration;
performing Layer-3 filtering on a result of the measurement using a predetermined filter operation;
