Abstract

a presente invenção se refere a técnicas para comunicação sem fio em um dispositivo sem fio. um método inclui a identificação de uma prioridade do dispositivo sem fio durante um intervalo de transmissão de um faixa do espectro de radiofrequência compartilhado por uma pluralidade de entidades operacionais da rede; identificação de uma ausência de um tipo de transmissão predeterminado em cada um dentre vários slots de avaliação de canal livre (cca) do intervalo de transmissão, em que cada um dos vários slots de cca é associado a uma prioridade mais alta que a prioridade identificada do dispositivo sem fio; e comunicação através da faixa do espectro de radiofrequência com base, pelo menos em parte, na ausência identificada do tipo de transmissão predeterminado em cada um dos vários slots de cca associados à prioridade mais alta do que a prioridade do dispositivo sem fio.
