Abstract

método e aparelho para indicação de acesso aleatório, e, meio de armazenamento legível por computador não transitório. são descritos um método e aparelho de indicação de acesso aleatório e um meio de armazenamento, relacionado ao campo técnico das comunicações. o método compreende: uma estação base de serviço enviando sinalização de indicação de acesso aleatório, a sinalização de indicação de acesso aleatório indicando, para um terminal, um painel de antena alvo e/ou feixe alvo para enviar um preâmbulo de acesso aleatório; e o terminal recebendo a sinalização de indicação de acesso aleatório e determinando, de acordo com a sinalização de indicação de acesso aleatório, o painel da antena alvo e/ou feixe alvo para enviar o preâmbulo de acesso aleatório. nas modalidades da presente descrição, uma estação base de serviço envia sinalização de indicação de acesso aleatório para um terminal, de modo que o terminal pode determinar um painel de antena alvo e/ou feixe alvo para enviar um preâmbulo de acesso aleatório em conformidade. desta forma, quando o terminal tem vários painéis de antena, o terminal pode determinar com precisão qual painel de antena usar para iniciar o acesso aleatório, facilitando assim uma melhoria na precisão e na taxa de sucesso do acesso aleatório e reduzindo o atraso do acesso aleatório.
