Abstract
"MéTODO PARA CONTROLAR NìVEIS DE POTêNCIA DETRANSMISSãO EM UM SISTEMA DE COMUNICAçãO DUPLEXPOR DIVISãO DE TEMPO DE ESPECTRO ESPALHADO,SISTEMA DE COMUNICAçãO DUPLEX POR DIVISãO DETEMPO DE ESPECTRO ESPALHADO, E, ESTAçãO DECOMUNICAçãO". A invenção controla níveis de potência detransmissão em uma estação de comunicação duplex por divisãode tempo de espectro espalhado. Uma primeira estação decomunicação (110) transmite uma comunicação a uma segundaestação de comunicação (112). A segunda estação recebe acomunicação e mede seu nível de potência recebido. Baseado,em parte, no nível de potência da comunicação recebida, umaestimativa de perda de trajeto e uma estimativa de perda de trajetode longo prazo são determinadas. Uma qualidade da estimativa deperda de trajeto também é determinada baseada na diferença detempo entre estimativa da perda de trajeto e o intervalo de tempode transmissão seguinte. O nível de potência de transmissão parauma comunicação da segunda estação para a primeira estação ébaseado, em parte, em ponderar a estimativa de perda de trajeto ea estimativa de perda de trajeto de longo prazo em resposta aqualidade de estimativas.
