A method is proposed for managing communications in a wireless network in which a first communication is set up or established on a plurality of carriers between a first sender device and a receiver device, the network comprising a set of at least one second sender device for which a second communication has to be established simultaneously with said first communication.Such a method comprises steps of: allocating a set comprising at least one carrier among said plurality of carriers to each second sender device; obtaining (, for each second sender device, a level of reception power of a predetermined signal sent by said second sender device on the set of carrier(s) that have been allocated to it; estimating a rate of disturbance of said first communication by one said or several said second communications as a function of the power level(s) obtained for the second sender device(s); authorizing the second sender device(s), for which the estimated rate(s) of disturbance is or are below a predefined threshold, to set up a said second communication on the plurality of carriers.
