Abstract

"CODIFICAçãO ACK/NAK DE HARQ PARA UM DISPOSITIVO DE COMUNICAçãO DURANTE A TRANFERêNCIA SUAVE". A invenção descreve um método para a seleção de velocidade através de um dispositivo de comunicação para o enlace ascendente aprimorado durante a transferência suave em um sistema de comunicação sem fio incluindo uma primeira etapa de recebimento da informação do escalonador. Esta informação pode incluir um ou mais dentre escalonamento, um limite de velocidade, um limite de margem de energia, e uma persistência. A etapa seguinte inclui a determinação de uma velocidade de dados para um enlace ascendente aprimorado durante a transferência suave utilizando a informação. A etapa seguinte inclui a transmissão para uma estação base servidora em um canal de enlace ascendente aprimorado na velocidade de dados determinada pela etapa de determinação.
