Abstract

posicionamento de equipamento de usuário (ue) com base em tempo de ida e volta (rtt) auxiliado por superfície inteligente reconfigurável (ris). são reveladas técnicas para posicionamento. em um aspecto, uma entidade de posicionamento recebe um relatório indicando um modo de operação de uma superfície inteligente reconfigurável (ris) associada a pelo menos uma estação base, recebe uma) medição de diferença de tempo de transmissão até recepção (tx- rx para um nó de rede envolvido em uma sessão de posicionamento de tempo de ida e volta (rtt) com um equipamento de usuário (ue), determina uma medição de diferença de tempo de recepção até transmissão (rx-tx) para o ue, a medição de diferença de tempo rx-tx representando uma diferença entre um tempo de recepção no ue de um sinal de referência de posicionamento de enlace descendente a partir da ris e um tempo de transmissão a partir do ue de um sinal de referência de posicionamento de enlace ascendente em direção à ris, e calcula uma distância entre o ue e a ris com base, pelo menos em parte, na medição de diferença de tempo tx-rx e na medição de diferença de tempo rx-tx.
