Abstract
sistema e método para acesso aleatório físico base ado em feixe um método em um dispositivo sem fio para executar acesso aleatório para um nó de rede. o método compreende receber um conjunto de sinais de referência específicos de feixe downlink, brs, a partir do nó de rede, e determinar um brs preferido com base na potência de sinal recebido para cada brs. o método também compreende selecionar, com base no brs preferido, um recurso de acesso aleatório a ser usado para transmitir uma tentativa de acesso aleatório para o nó de rede, bem como usar o recurso de acesso aleatório selecionado ao transmitir uma tentativa de acesso aleatório para o nó de rede, pelo que a seleção de recurso de acesso aleatório indica para o nó de rede qual feixe downlink é preferido pelo dispositivo sem fio a ser usado para transmissões downlink.
