Abstract
"MéTODO PARA TRANSMISSãO E RECEPçãO DE DADOS EM UM SISTEMA DE COMUNICAçãO MóVEL". Um método de transmissão de PLP em um sistema de comunicação móvel é fornecido. A estação base determina uma velocidade de dados de encaminhamento de acordo com a informação de DRC recebida de uma estação móvel, lê EPs temporários de um tamanho total máximo das memórias provisórias, determina se os EPs temporários podem ser transmitidos na velocidade de dados, forma uma combinação de EPs lógicos dos EPs temporários se os EPs temporários podem ser transmitidos na velocidade de dados e o tamanho total dos EPs temporários é igual ou maior que o limite, e transmite os EPs lógicos em um PLP.
