Signalling method, intended to be implemented by a base station of a cellular telecommunications network, this base station controlling at least one cell of the network, the signalling method comprising: - a step of assignment, to an interfering terminal attached to said cell and identified by the base station as being likely to interfere with at least one communication set up by another terminal (T1', T2) attached to said cell or to a neighbouring cell: ∘ of a so-called open network temporary identifier (RNTIo1), intended to be shared by a predetermined number of interfering terminals attached to the cell controlled by the base station; said method characterized in that said assignment step further comprises the assignment ∘ of a code making it possible to identify the interfering terminal out of this predetermined number of interfering terminals; and in that said method further comprises: - a step of publication of this open network temporary identifier to the terminals attached to said cell and/or to at least one other cell controlled by the base station and neighbouring said cell and/or to at least one base station controlling a cell neighbouring said cell; - a step of sending to the interfering terminal, in at least one configuration message, of the open network temporary identifier (RNTIo1) and of the code which are assigned to it; and - a step of insertion of this code, into a field of a physical control channel intended for the interfering terminal and allocating transmission resources on the cellular network to the interfering terminal, this physical channel being coded using the open network temporary identifier assigned to the interfering terminal and transmitted over the network. - a step of assignment, to an interfering terminal attached to said cell and identified by the base station as being likely to interfere with at least one communication set up by another terminal (T1', T2) attached to said cell or to a neighbouring cell: ∘ of a so-called open network temporary identifier (RNTIo1), intended to be shared by a predetermined number of interfering terminals attached to the cell controlled by the base station; said method characterized in that said assignment step further comprises the assignment ∘ of a code making it possible to identify the interfering terminal out of this predetermined number of interfering terminals; ∘ of a so-called open network temporary identifier (RNTIo1), intended to be shared by a predetermined number of interfering terminals attached to the cell controlled by the base station; ∘ of a code making it possible to identify the interfering terminal out of this predetermined number of interfering terminals; - a step of publication of this open network temporary identifier to the terminals attached to said cell and/or to at least one other cell controlled by the base station and neighbouring said cell and/or to at least one base station controlling a cell neighbouring said cell; - a step of sending to the interfering terminal, in at least one configuration message, of the open network temporary identifier (RNTIo1) and of the code which are assigned to it; and - a step of insertion of this code, into a field of a physical control channel intended for the interfering terminal and allocating transmission resources on the cellular network to the interfering terminal, this physical channel being coded using the open network temporary identifier assigned to the interfering terminal and transmitted over the network.
