Abstract

La présente invention concerne un procédé de communication sans fil, au moyen duquel l'interférence d'une liaison croisée peut être obtenue par une utilisation correcte d'une ressource de réseau, et il n'y a pas de conflit avec la transmission de données lors de l'obtention de l'interférence de la liaison croisée. Le procédé est appliqué dans un système duplex à répartition dans le temps, et de multiples dispositifs réseau dans le système allouent dynamiquement une bande passante en tant que ressource de liaison montante ou ressource de liaison descendante respectivement. Le procédé consiste à déterminer qu'un premier dispositif réseau n'a pas de transmission de données dans une première période de temps; mesurer une intensité de signal dans une bande passante du système dans la première période de temps; et déterminer, en fonction de l'intensité de signal mesurée, un degré d'interférence généré lorsqu'un autre dispositif réseau dans un système envoie un signal sans fil.
