Abstract

são aqui divulgados um detector de unidade de recurso ativo e um método de utilização do mesmo. um método de realização de detecção de unidades de recursos ativos entre uma pluralidade de unidades de recursos potenciais inclui a recepção de um sinal agregado contendo pilotos ativos transmitidos através de unidades de recursos ativos via transmissões de acesso aleatório. os pilotos ativos são então detectados e respectivamente associados com as unidades de recursos ativos de acordo com um mapeamento de unidade de piloto-a-recurso.
