Abstract

CONTROLE DE POTÊNCIA DE UMA ESTAÇÃO DE TRANSMISSÃO EM UMA REDE SEM FIO. Uma rede sem fio inclui uma estação base e uma estação transmissora para estender a cobertura sem fio da estação base. Os dados de enlace descendente são enviados pela estação base e transmitidos através da estação transmissora para uma estação móvel, onde os dados de enlace descendente são associados com um preâmbulo que é enviado diretamente a partir da estação base para a estação móvel. Uma potência de transmissão da estação transmissora é ajustada para transmitir dados de enlace descendente da estação transmissora para a estação móvel para reduzir uma diferença entre um primeiro nível de potência do preambulo recebido na estação móvel e um segundo nível de potência de dados de enlace descendente recebidos na estação móvel. A potência de transmissão de enlace ascendente da estação móvel para os dados enviados para a estação transmissora ajustada para compensar a diferença na perda de percurso da estação móvel para a estação base e da estação móvel para a estação transmissora e para compensar a diferença no nível de ruido mais interferência na estação transmissora com comparação dom o da estação base.
