Title
(EN) DYNAMIC GROUP FORMATION FOR GROUP BASED POSITIONING REFERENCE SIGNAL LISTEN BEFORE TALK PROCEDURES
(FR) FORMATION DE GROUPE DYNAMIQUE POUR PROCÉDURES D'ACCÈS MULTIPLE AVEC ÉCOUTE DE PORTEUSE DE SIGNAL DE RÉFÉRENCE DE POSITIONNEMENT BASÉES SUR UN GROUPE
Abstract
(EN) Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an initiator UE, a group formation communication indicating a group that the UE is associated with for a group positioning reference signal (PRS) Listen Before Talk (LBT) procedure. The UE may transmit, to the initiator UE, an indication that the UE should not be associated with the group based at least in part on performing the group PRS LBT procedure. Numerous other aspects are provided.
(FR) Divers aspects de la présente divulgation portent d'une manière générale sur la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut recevoir, en provenance d'un UE initiateur, une communication de formation de groupe indiquant un groupe auquel est associé l'UE pour une procédure d'accès multiple avec écoute de porteuse (LBT) de signal de référence de positionnement (PRS) de groupe. L'UE peut émettre, vers l'UE initiateur, une indication selon laquelle l'UE ne devrait pas être associé au groupe sur la base, au moins en partie, de la réalisation de la procédure de LBT de PRS de groupe. La divulgation concerne également de nombreux autres aspects.
