Abstract

"BALANCEAMENTO DE INTERFERêNCIA EM UM SISTEMA DE COMUNICAçãO SEM FIO". A presente invenção refere-se a um método para balancear a distribuição de interferência entre as células de rádio em um sistema de comunicação sem fio que compreende células nas quais os blocos de subveículos são utilizados para a usadas. Um número de células adjacentes constrói um grupamento de células. Mais ainda, a presente invenção refere-se a um método correspondente adaptado para utilização em um sistema no qual antenas de múltiplos feixes ou múltiplas antenas são utilizadas. Mais ainda, a presente invenção refere-se a estações de base para executar o método acima assim como um sistema de comunicação que compreende as estações de base. Para reduzir as grandes variações de SIR média sem causar uma estimativa de SIR adicional, um problema de medição e de cálculo como introduzido com o controle de potência da invenção sugere agrupar os blocos de subveículos em uma pluralidade de conjuntos de blocos de subveículos em cada célula de um grupamento de células, para determinar os níveis de potência de transmissão para cada uma das células do dito grupamento de células, e atribuir níveis de potência de transmissão aos conjuntos de blocos de subveículos.
