Title
(EN) USER-EQUIPMENT-COORDINATION SET FOR A WIRELESS NETWORK
(FR) ENSEMBLE DE COORDINATION D'ÉQUIPEMENT UTILISATEUR POUR UN RÉSEAU SANS FIL
Abstract
(EN)
This document describes techniques and apparatuses for a user equipment (UE)-coordination set for a wireless network. In aspects, a base station (120) specifies a set of UEs (110) to form a UE-coordination set (306) for joint transmission and reception of data intended for a target UE (112) within the UE-coordination set. The base station selects one of the UEs within the UE-coordination set to act as a coordinating UE (111) for the UE-coordination set and transmits a request message that directs the coordinating UE to coordinate the joint transmission and reception of the data intended for the target UE. Then, the base station transmits a downlink signal to each UE within the UE-coordination set. Each UE within the UE-coordination set demodulates and samples the downlink signal and then forwards the samples to the coordinating UE, which combines the samples and processes the combined samples to provide decoded data.

L'invention concerne des techniques et des appareils pour un ensemble de coordination d'équipement utilisateur (UE) pour un réseau sans fil. Selon certains aspects, une station de base (120) spécifie un ensemble d'UE (110) pour former un ensemble de coordination d'UE (306) pour une transmission et une réception conjointes de données destinées à un UE cible (112) dans l'ensemble de coordination d'UE. La station de base sélectionne l'un des UE à l'intérieur de l'ensemble de coordination d'UE pour agir en tant qu'UE de coordination (111) pour l'ensemble de coordination d'UE et transmet un message de requête qui dirige l'UE de coordination pour coordonner la transmission et la réception conjointe des données destinées à l'UE cible. Ensuite, la station de base transmet un signal de liaison descendante à chaque UE dans l'ensemble de coordination d'UE. Chaque UE dans l'ensemble de coordination d'UE démodule et échantillonne le signal de liaison descendante et transmet ensuite les échantillons à l'UE de coordination, qui combine les échantillons et traite les échantillons combinés pour fournir des données décodées.
