Abstract

"SISTEMA E MéTODO PARA COMBINAR COMANDOS DE CONTROLE DE FORçA DURANTE O HANDOFF SUAVE EM SISTEMAS CELULARES DS/CDMA" Trata-se de estações móveis em comunicação com várias estações base em um sistema celular CDMA (como quando suportando o handoff suave) que não utilizam a regra "ouro da chapada" convencional para estimar a qualidade dos comandos de controle de força das estações base. As estações móveis estimam a qualidade da qualidade dos links da estação base. Se qualquer estação base exibir a qualidade do link acima de um limite predeterminado e se esta estação base estiver requisitando a redução de força, a força é reduzida por uma valor predeterminado, delta. Caso contrário, a força é ajustada para cima ou para baixo por um valor menor ou igual a delta de acordo com os sinais de controle de força recebidos a partir de cada estação base em conjunto com um peso determinado a partir da qualidade do sinal do link de cada estação base.
