Abstract

PROCESSO PARA A DETERMINAçãO DE UM VALOR DA POTêNCIA DE TRANSMISSãO PARA UM SINAL A SER EMITIDO POR UMA ESTAçãO TRANSMISSORA PARA UMA ESTAçãO RECEPTORA, BEM COMO, DISPOSITIVO. A invenção se refere a um processo para a determinação de um valor da potência de transmissão para um sinal (S1, S2, S3) a ser transmitido de uma estação transmissora (NodeB) para uma estação receptora (UE), no lado de transmissão, para um primeiro valor da potência de transmissão é estimada a posição de um primeiro valor (P1, P2, P3) provável da potência de recepção da estação receptora (UE), em um intervalo da potência de recepção (I1, I2, I3) predeterminado. De acordo com a invenção, um segundo valor a ser empregado para a transmissão da potência de transmissão no lado de transmissão é determinado de tal modo que, no caso de seu emprego, um segundo valor (P1<39>, P2<39>, P3<39>) provável da potência de recepção fica mais próximo do centro do intervalo da potência de recepção (I1, I2, I3) predeterminado do que o primeiro valor (P1, P2, P3) provável da potência de recepção.
