Embodiment Construction

[0075] In the following description, for purposes of explanation rather than limitation, specific details are set forth, such as specific architectures, interfaces, techniques, etc., in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0076] The present invention relates to a base station in a wireless communication system, which may be a mobile communication system like Universal Mobile Telecommunications System (UMTS) and / or Long Term Evolution (LTE). The system is also a system that uses or operates according to a synchronous time division scheme such as a time division duplex system (TDD). In the example of...

Abstract

A first base station (14) in a wireless communication system (10) operating according to a synchronised time division scheme detects interference of uplink communication, determines the delay of the interference in relation to an own communication structure (CS1), detects aerial interface identifying data of the source of interference identifying a further base station and sends an indication of the further base station interfering uplink communication to the interference handling node (22). The indication is accompanied by identification data comprising aerial interface identifying data of the further base station and distance data determining the distance (D1) between the first and the further base station. The interference handling node (37) receives the indication with accompanying identification data, investigates the identification data in order to determine the identity of a candidate for the further base station and orders the candidate base station to perform an interference limitation activity.

Description

technical field [0001] The present invention relates to interference between base stations in a wireless communication system. More specifically, the present invention relates to a method and a computer program product for handling interference in a wireless communication system operating according to a synchronous time division scheme, an interference handling node in such a wireless communication system, a method for handling interference in such a wireless communication system A method for reporting interference in a wireless communication system and a first base station in such a wireless communication system. Background technique [0002] Today, there are many mobile communication systems using synchronous time division schemes such as time division duplex systems (TDD). One example of such a scheme is Time Division Long Term Evolution (TD-LTE). [0003] These types of systems provide base stations with some communication structure, such as frames or subframes provide...
