Problems solved by technology

[0029] However, frequency allocation to different cells reduces the available uplink resources per cell very significantly (e.g. by a factor of 1 / 3 or 1 / 7) and thus reduces the overall system throughput
For the internal area of ​​the cell, this is a waste of resources
[0030] Frequency reuse of e.g. 1 / 3 only outside the cell is possible, but still wastes too much resources

Embodiment Construction

[0066] A mobile network according to the invention comprises mobile terminals and base stations.

[0067] Each of said mobile terminals is connected to one or more of said base stations, and the base stations are then connected to the core network via a base station controller.

[0068] A mobile terminal comprises mobile terminal functionality for transmitting and receiving in a single frequency network, eg an OFDM network, ie the mobile terminal can be connected to the mobile network via a base station.

[0069] Furthermore, the mobile terminal according to the invention comprises means for assessing in which cell or cell area the mobile terminal has generated interference by means of downlink interference or path loss measurements, and the mobile terminal comprises means for requesting to be scheduled to the Means wherein the mobile terminal generates a dedicated subset of the most interfering cell or cell area.

[0070] A base station comprises the functionality of a base ...

Abstract

The invention concerns a method for coordination of the interference in the uplink between cells (C1,C6) of a single frequency network with the frequency band used for uplink being subdivided into at least two subsets (F1 F2...FR), whereby a dedicated subset (F1) of said at least two subsets (F1 F2...FR) is selected to be burdened more by inter-cell interference and is allocated under observation of the strong inter-cell interference in this dedicated subset to mobile terminals located in a first cell (C1), and mobile terminals (T2) located in the border area of a second cell (C6) of said cells neighbored to the first cell and causing the strongest interference in said first cell (C1) are based on further network criteria tried to be scheduled to said dedicated subset (F1), a base station, a mobile terminal and a mobile network therefor.

Description

[0001] Cross References to Related Applications [0002] The present invention is based on European priority application EP 05291278.9, the content of which is hereby incorporated by reference. technical field [0003] The invention relates to a method for coordinating interference in the uplink between cells of a single frequency network by subdividing the frequency band used for the uplink into at least two subsets, wherein: [0004] selecting a dedicated subset of the at least two subsets that is more burdened by inter-cell interference, and assigning the dedicated subset in case strong inter-cell interference is observed in the dedicated subset assigned to a mobile terminal located in a first cell of the plurality of cells or in an area of ​​the first cell; and [0005] Attempts, based on additional network criteria, to place in the border region of a second cell of the plurality of cells adjacent to the first cell and in the first cell or the first cell of the first cell...
