Abstract
seleção de sinal de referência de posicionamento sob demanda para esquemas ed posicionamento de diferênca dupla. técnicas são proporcionadas para configurar recursos de sinal de referência de posicionamento (prs) sob demanda em métodos de posicionamento de dupla diferença (dd). um método ilustrativo para proporcionar uma solicitação de sinal de referência de posicionamento sob demanda inclui receber vários valores de medição de sinal de referência de posicionamento de um equipamento do usuário alvo e pelo menos um nó de referência, determinar um ou mais sinais de referência de posicionamento sob demanda baseado, pelo menos em parte, na informação de identificação de sinal associada a cada um dos vários valores de medição de sinal de referência de posicionamento e enviar uma indicação de um ou mais sinais de referência de posicionamento sob demanda para qualquer um dentre os equipamentos de usuário alvo, o pelo menos um nó de referência, ou ambos.
