20100248736 | Inter-System Interference Control - It is provided a solution for controlling interference in a cellular telecommunication system. An interference controller of the cellular telecommunication utilizes interference level information received from another cellular telecommunication system in controlling interference towards a target cell suffering from high interference which degrades the grade of service in the target cell. The interference level information comprises information on levels of interference between neighboring cells of the other cellular telecommunication system. The interference controller analyzes the received interference level information and controls communication links in cells of the cellular telecommunication system determined to cause the highest interference towards the target cell. The cells determined to cause the highest interference towards the target cell are determined from the received interference level information. | 09-30-2010 |
20130225159 | Interference Management for Coexisting Radio Systems - The invention relates to apparatuses, a method, computer program and computer-readable medium for resource allocation (selection of channel and maximum allowed transmission power) in a coexisting secondary communications system, overlapping with a primary system. Allocation is performed based on an interference table indicating measured interference per cell of the primary system from other cells of the primary and secondary system. | 08-29-2013 |

20130258979 | Spectrum Sharing - The invention relates to apparatuses, a method, computer program and computer-readable medium. | 10-03-2013 |
20130343315 | Signalling a Muting Pattern to a User Equipment for Time Domain Enhanced Inter-Cell Interference Coordination - A method for controlling radio resource usage in a communications system is described. The method includes defining in a network apparatus, a muting pattern regarding uplink signals that are to be temporarily muted, wherein said uplink signals include higher layer configured uplink signals that are outside the control of a dynamic scheduler of the network apparatus. The defined muting pattern or a part of it is signalled from the network apparatus to one or more user equipment in order to control the user equipment to mute the respective uplink signals according to the signalled muting pattern. | 12-26-2013 |
20140038628 | Apparatus and Method for Communication - Apparatus and method for communication are provided. The solution includes a first server of an operator specific communication system configured to perform the administration and management tasks of the operator specific communication system including one or more radio access technologies, communicate with the respective server of one or more communication systems of another operators, and a second server configured to manage mobility policy of the operator specific communication sys-tem, communicate with the user terminals of the system by transmitting information on inter-system radio access network selection and access, wherein the first and second server are configured each to maintain an interworking data model including information on operator specific cognitive radio parameters and access policies related to networks of one or more operators. | 02-06-2014 |
20140315561 | Inter-System Interference in Communications - An inter-system interference estimation method is disclosed for both primary and secondary radio systems. In the case of a primary system (such as a GSM system), inter-system interference estimation is based on a comparison of cell level measurement statistics before and after secondary spectrum usage in neighbouring cells. In the case of a secondary system (such as an LTE system), inter-system interference estimation is based on a measurement on secondary spectrum before starting transmission on the secondary spectrum. Based on both of the above mentioned inter-system inter-cell interference estimations, a cell-level decision on the secondary spectrum usage is made, and optimization of radio resource allocation inside the systems may be carried out. | 10-23-2014 |
20150245333 | CONFIGURATION OF A SHARED FREQUENCY BAND BETWEEN WIRELESS COMMUNICATIONS SYSTEMS - A receiving node of a first wireless communications system is co-located with a node of a second wireless communications system, said first and second wireless communications systems are configured with frequencies on a shared frequency band. Information identifying a node of the first wireless communications system transmitting on the shared frequency band is received. The received information identifying the transmitting node as an interfering node to the co-located node of the second wireless communications system is transmitted to an entity controlling configuration of the shared frequency band. | 08-27-2015 |
