Abstract

terminal de usuário e método de radiocomunicação. um terminal de usuário inclui: uma seção de controle configurada para determinar uma relação espacial, em um caso onde informações de relação espacial indicando a relação espacial de transmissão de enlace ascendente específica não são configuradas ou em um caso onde um parâmetro específico é configurado pelas informações de relação espacial, com base em se ou não um deslocamento de tempo entre recepção de um primeiro canal de controle de enlace descendente e recepção de um canal de enlace descendente escalonado pelo primeiro canal de controle de enlace descendente é igual ou maior que um limiar; e uma seção de transmissão configurada para desempenhar a transmissão de enlace ascendente específica utilizando a relação espacial.
