Abstract

POSICIONAMENTO PASSIVO COM ASSISTÊNCIA DE ENLACE LATERAL. Técnicas são fornecer para posicionamento passivo de equipamento de usuário (UE) com assistência de enlace lateral. Um método exemplificativo para posicionamento passivo inclui receber um primeiro sinal de referência de posicionamento a partir de uma primeira estação em um primeiro horário, receber um segundo sinal de referência de posicionamento a partir de uma segunda estação em um segundo horário, receber dados de assistência de posicionamento associados a sinais de referência de posicionamento recebidos por um equipamento de usuário próximo, determinar uma diferença de temporização de sinal de referência com base pelo menos em parte no primeiro horário e no segundo horário, e determinar uma localização atual com base pelo menos em parte na diferença de temporização de sinal de referência e nos dados de assistência de posicionamento
