Title
(EN) ENVIRONMENT-AWARE POSITIONING REFERENCE SIGNAL (PRS)
(FR) SIGNAL DE RÉFÉRENCE DE POSITIONNEMENT SENSIBLE À L'ENVIRONNEMENT (PRS)
Abstract
(EN) Disclosed are various techniques for wireless communication. In an aspect, a method of wireless communication includes determining, based on environment information about an environment in which a user equipment (UE) that is receiving positioning reference signals (PRSs) using a first bandwidth (BW) is operating, a second BW to be used by the UE for receiving PRSs, and transmitting PRSs using the second BW to be used by the UE for receiving PRSs.
(FR) L'invention concerne diverses techniques de communication sans fil. Selon un aspect, un procédé de communication sans fil consiste à déterminer, sur la base d'informations d'environnement concernant un environnement dans lequel fonctionne un équipement utilisateur (UE) qui reçoit des signaux de référence de positionnement (PRS) à l'aide d'une première largeur de bande (BW), une seconde BW destinée à être utilisée par l'UE pour recevoir des PRS, et à transmettre des PRS à l'aide de la seconde BW à utiliser par l'UE pour recevoir des PRS.
