Title
(EN) NON-ORTHOGONAL MULTIPLE ACCESS CONFIGURATION IN SPLIT BASE STATION ARCHITECTURES
(FR) CONFIGURATION D'ACCÈS MULTIPLE NON ORTHOGONAL DANS DES ARCHITECTURES DE STATIONS DE BASE DIVISÉES
Abstract
(EN)
The present disclosure describes techniques and apparatuses for non-orthogonal multiple access (NOMA) configuration procedures in split base station architectures, including the configuration of user equipment (UE) for NOMA transmission. The base station (120) receives a trigger (310; 410; 510; 610; 710; 810; 910; 1010) relating to a UE (110). Responsive to the trigger, the base station configures the UE to perform NOMA transmission by at least one of a Central Unit (121) of the base station transmitting a first message including the NOMA configuration to a Distributed Unit (122) of the base station and transmitting a second message including the NOMA configuration to the UE, the Central Unit transmitting the second message including the NOMA configuration to the UE, or the Distributed Unit transmitting a third message including the NOMA configuration to the Central Unit and the Central Unit transmitting the second message including the NOMA configuration to the UE.

La présente invention concerne des techniques et des appareils pour des procédures de configuration d'accès multiple non orthogonal (NOMA) dans des architectures de stations de base divisées, comprenant la configuration d'un équipement utilisateur (UE) pour une transmission NOMA. La station de base (120) reçoit un déclenchement (310, 410, 510, 610, 710, 810, 910, 1010) qui se rapporte à un UE (110). En réponse au déclenchement, la station de base configure l'UE afin d'effectuer une transmission NOMA par une unité centrale (121) de la station de base transmettant un premier message comprenant la configuration NOMA à une unité distribuée (122) de la station de base et transmettant un deuxième message comprenant la configuration NOMA à l'UE, et/ou l'unité centrale transmettant le deuxième message comprenant la configuration NOMA à l'UE, et/ou l'unité distribuée transmettant un troisième message comprenant la configuration NOMA à l'unité centrale et l'unité centrale transmettant le deuxième message comprenant la configuration NOMA à l'UE.
