Abstract

1/1 resumo “operações de avaliação de canal limpo lte-u” a tecnologia sujeita prevê a realização de avaliação de canal limpo (cca) em lte-u. as transmissões podem ser monitorizadas em um recurso reservado para cca. uma energia das transmissões é detectada ao longo de um período mais curto que uma partição atribuída no recurso reservado para cca. um sinalizador pode ser transmitido em uma partição atribuída a uma entidade sem fio para cca em resposta à detecção de um canal limpo com base na monitorização. em outro aspecto, uma transmissão de sinalizador para a cca e uma temporização para a monitorização são adaptadas em resposta à detecção das transmissões para um número consecutivo de períodos de cca. além disso, a tecnologia sujeita provê ajustar a uma potência máxima para transmissão de um sinalizador em uma partição atribuída a uma estação móvel para cca em resposta à detecção de um canal limpo com base na monitorização.
