Abstract

a presente invenção refere-se a um sistema de comunicações sem fio (100) que compartilha uma banda predeterminada com outro sistema de comunicação sem fio. cada terminal (120, 130) inicia um processamento de detectar um sinal sem fio na banda predeterminada em um tempo predeterminado compartilhado entre os terminais (120, 130). os terminais (120, 130) iniciam cada um uma transmissão de sinal sem fio, usando entre a mesma banda ou em bandas diferentes as banda incluídas na banda predeterminada em um tempo em que um estado no qual um sinal sem fio não é detectado na banda predeterminada continuou por uma extensão de tempo predeterminada, o dito tempo sendo compartilhado entre os terminais (120, 130).
