Abstract

"MéTODO DE CONTROLE DE TAXA DE TRANSMISSãO, ESTAçãO RáDIO BASE E CONTROLADOR DE REDE DE RáDIO". Um método de controle de taxa de transmissão inclui: a medição, em uma estação rádio base, de uma potência de recepção de um DPCH transmitido a partir da estação móvel; a extração, na estação rádio base, de um tamanho de bloco de dados de transmissão dos dados de usuário de enlace ascendente a partir de um E-DPCCH; a aquisição, na estação rádio base, de uma relação de potência de recepção do EDPDCH para o DPCCH, o qual corresponde ao tamanho de bloco de dados de transmissão; o cálculo, na estação rádio base, de uma potência de recepção do E-DPDCH com base na potência de recepção medida e na relação de potência de recepção adquirida; o cálculo, na estação rádio base, de uma taxa de transmissão relativa dos dados de usuário de enlace ascendente com base na potência de recepção calculada; a notificação, na estação rádio base, da taxa de transmissão relativa dos dados de usuário de enlace ascendente para a estação móvel através de um E-RGCH; e o controle, na estação móvel, da taxa de transmissão dos dados de usuário de enlace ascendente com base na taxa de transmissão relativa notificada.
