Abstract

"CONTROLE DE POTêNCIA DE CONVERGêNCIA RáPIDA PARA SISTEMAS DE COMUNICAçãO SEM FIO" São descritas técnicas para ajustar rapidamente uma SIR meta para um valor final necessário para obter uma BLER meta especificada para uma transmissão de dados. O loop externo pode ser implementado com múltiplos modos. A SIR meta pode ser mantida fixa em um modo de espera, ajustada em grandes etapas ou degraus descendentes para acelerar a convergência em um modo de captação e ajustada por uma pequena etapa descendente e uma grande etapa ascendente para blocos bons e apagados, respectivamente, em um modo de seguimento. Vários esquemas podem ser usados para ajustar a SIR meta em etapas descendentes maiores no modo de captação. Tais esquemas podem ser usados mesmo se dados são transmitidos intermitentemente, a BLER meta é ajustada para um valor baixo e/ou múltiplos canais de transporte são usados para transmissão de dados. A SIR meta pode ser amplificada em uma quantidade particular ao passar do modo de captação para o modo de seguimento.
