Abstract

1/1 resumo “técnicas para avaliar canal livre em uma banda de espectro de radiofrequência não licenciada” trata-se de técnicas descritas para comunicações sem fio que utilizam múltiplos procedimentos de avaliações de canal livre (cca) para acesso a uma banda de espectro de radiofrequência. um primeiro procedimento de cca é realizado para determinar a disponibilidade da banda de espectro de radiofrequência e para competir pelo uso da banda de espectro de radiofrequência entre várias operadoras coordenadas que realizam transmissão na banda de espectro de radiofrequência. um primeiro procedimento de cca bem-sucedido resulta em conseguir a competição para a banda de espectro de radiofrequência por um período de transmissão que é coordenado entre a quantidade de operadoras coordenadas. mediante o primeiro procedimento de cca bem-sucedido, um segundo procedimento de cca é realizado durante um período de transmissão descontínua (dtx) no período de transmissão para determinar a disponibilidade contínua da banda de espectro de radiofrequência. a sincronização dos períodos de dtx é determinada com base na sincronização de transmissões de rádio que têm prioridade de uso da banda de espectro de radiofrequência.
