Title
(EN) POINT-TO-MULTIPOINT SHARED-ACCESS FULL-DUPLEX WIRELESS DUPLEXING SCHEME ASSOCIATED WITH SPATIAL DIVERSITY

Abstract
(EN) A wireless communication network for communicating information between a base station and a plurality of UEs is described. In accordance with a first aspect the base station concurrently transmits to and receives from a plurality of UEs using a spatial diversity and a frequency division multiplexing, FDM, communication. In accordance with a second aspect the base station concurrently transmits to and receives from a plurality of UEs using a frequency division multiplexing, FDM, communication without spatial diversity. In accordance with a third aspect the base station concurrently transmits to and receives from a plurality of UEs using a spatial diversity and a time division multiplexing, TDM, communication. In accordance with a fourth aspect the base station concurrently transmits to and receives from a plurality of UEs a time division multiplexing, TDM, communication without spatial diversity, and wherein the UEs employ beamforming for inter-UE-interference suppression.
(FR) La présente invention concerne un réseau de communication sans fil pour communiquer des informations entre une station de base et une pluralité d'interfaces utilisateurs (UE). Selon un premier aspect, la station de base émet simultanément vers et reçoit d'une pluralité d'UE à l'aide d'une diversité spatiale et d'un multiplexage par répartition en fréquence (FDM). Selon un second aspect, la station de base transmet simultanément à une pluralité d'UE et reçoit en provenance d'une pluralité d'UE à l'aide d'un multiplexage par répartition en fréquence (FDM), sans diversité spatiale. Selon un troisième aspect, la station de base émet simultanément vers et reçoit d'une pluralité d'UE à l'aide d'une diversité spatiale et d'une communication par multiplexage par répartition dans le temps (TDM). Selon un quatrième aspect, la station de base transmet simultanément et reçoit en provenance d'une pluralité d'UE une communication par multiplexage par répartition dans le temps (TDM), sans diversité spatiale, et les UE employant une formation de faisceau pour une suppression d'interférence inter-UE.
