Abstract

um projeto de forma de onda de canal físico de acesso aleatório (prach) para satisfazer as exigências com relação à largura de banda de canal ocupada em rede de comunicações sem fio elaa é fornecido. em uma alternativa, prach compreende múltiplos segmentos no domínio do tempo/frequência em um subquadro. em uma outra alternativa, prach compreende múltiplos segmentos no domínio do tempo/frequência através de dois ou mais subquadros ao usar salto entre subquadros. em um aspecto vantajoso, pdcch ativa a alocação dinâmica do recurso prach para facilitar o procedimento de acesso a canal de ouvir antes de falar (lbt) em portadoras não licenciadas. a alocação aperiódica e dinâmica de recurso prach melhora eficiência e taxa de sucesso de prach.
