Abstract

"SELEçãO DA VELOCIDADE DE ENLACE ASCENDENTE APRIMORADA POR UM DISPOSITIVO DE COMUNICAçãO DURANTE TRANSFERêNCIA SUAVE". Um método para a seleção da velocidade por um dispositivo de comunicação para o enlace ascendente aprimorado durante a transferência suave em um sistema de comunicação sem fio inclui a primeira etapa de receber informação de um escalonador. Esta informação pode incluir um ou mais do escalonamento, um limite de velocidade, um limite de margem de energia, e uma persistência. A etapa seguinte inclui determinar a velocidade de dados para o enlace ascendente aprimorado durante a transferência suave utilizando a informação. A etapa seguinte inclui transmitir para uma estação base servidora em um canal de enlace ascendente aprimorado na velocidade de dados determinada pela etapa de determinar.
