Abstract: A server device, which includes a communication interface; a memory; and a processor operatively connected to the communication interface and the memory. The memory is configured to store a first database including identifiers of access points and location information. The processor is configured to: receive, from an external electronic device through the communication interface, an identifier of at least one access point including a first access point collected by the external device and an identifier of a base station, identify location information matching the identifier of the at least one access point and/or the identifier of the base station in the first database, and update location information matching an identifier of the first access point in the first database based on the identified location information.

Abstract: A method and an apparatus for cancelling interference in a wireless communication system are provided. The method includes acquiring interference signal information on a reception signal received from a base station based on a preconfigured constellation set, and cancelling an interference signal from the reception signal by using the acquired interference signal information. Accordingly, reception performance in a cell edge can be improved by acquiring dominant interference signal information.
