Abstract

uma rede de comunicações está sendo acessada por um dispositivo sem fio associado a uma classe de cobertura selecionada de um conjunto de classes de cobertura. o dispositivo sem fio desempenha um método que compreende iniciar o acesso de rede para a rede de comunicações por transmitir uma sequência de preâmbulo para acesso aleatório em um canal de acesso aleatório físico durante uma oportunidade de início definida pela classe de cobertura do dispositivo sem fio. cada classe de cobertura pode estar associada a um número único de repetições da transmissão de sequência de preâmbulo.
