Abstract

La présente demande divulgue, selon des modes de réalisation, un procédé de réception d'un signal de référence de positionnement (PRS) et un équipement utilisateur (UE). Le procédé de réception d'un PRS comprend : un UE reçoit des informations d'indication de signal de référence de positionnement apériodique (A-PRS), détermine selon les informations d'indication d'A-PRS un ensemble de ressources A-PRS déclenché par chaque TRP et reçoit ensuite, sur chaque ressource A-PRS dans l'ensemble de ressources A-PRS déclenché par chaque TRP, de façon à obtenir des résultats de mesure reçus de chaque PRS, les résultats de mesure de PRS obtenus étant des résultats de mesure des ressources A-PRS. Le procédé de réception d'un PRS permet à un UE d'obtenir des résultats de mesure de ressources A-PRS par déclenchement de la réception de ressources A-PRS lorsque l'UE se déplace et que la durée d'un PRS périodique n'a pas été atteinte. Par conséquent, la précision de positionnement d'OTDOA sur la base d'un PRS peut être améliorée et le retard de positionnement peut être réduit.
