Abstract

métodos, sistemas e dispositivos são descritos para seleção de nível de potência inicial em um canal de acesso aleatório físico em uma rede de comunicações sem fio. a seleção de nível de potência inicial pode ser considerada para, ou ser feita com base em, uma ou mais condições de canal associadas com o canal de acesso aleatório físico. a seleção de nível de potência inicial pode ter como base a sinalização de níveis de transmissão de potência inicial disponíveis e uma medição de potência recebida de sinal de referência. as características descritas podem ser implementadas como técnicas de aperfeiçoamento de cobertura, por exemplo, para comunicação do tipo de máquina (mtc).
