Abstract

a presente invenção se refere a métodos e aparelhos para um terminal de usuário (ut) para transmitir dados a um controlador de rede via satélite em um sistema de satélite. o ut pode começar a transmitir, durante um período de tempo, uma primeira parte dos dados utilizando recursos com base em contenção do sistema de satélite antes de receber uma concessão de recursos agendados no link de retorno do sistema de satélite. o ut também pode transmitir, quanto aos recursos com base em contenção, um relatório de status do buffer (bsr) durante o período de tempo. o ut pode encerrar as transmissões de dados quanto aos recursos com base em contenção após um término do período de tempo ou mediante o recebimento da concessão de recursos agendados no link de retorno. após receber a concessão, o ut pode transmitir uma segunda parte dos dados quanto aos recursos agendados no link de retorno.
