Abstract
(EN)
There is provided a method of wireless transmission between a base station (gNB) and a group of UEs (UE1-UE4). The base station transmits (102) a group Downlink Control Information (DCI) message to the group of UEs on a downlink control channel (PDCCH). The group DCI message comprises a group DCI indicating at least a first UE in the group and a second UE in the group which are scheduled to receive a transmission of data on a downlink data channel. The base station (gNB) transmits (103) a first data transmission to the first UE and a second data transmission to the second UE in accordance with the group DCI on the downlink data channel. The first data transmission and the second data transmission are spatially multiplexed.

L'invention concerne un procédé de transmission sans fil entre une station de base (gNB) et un groupe d'équipements utilisateur (UE) (UE1-UE4). La station de base transmet (102) un message d'informations de commande de liaison descendante (DCI) de groupe au groupe d'UE sur un canal de commande de liaison descendante (PDCCH). Le message de DCI de groupe comprend des DCI de groupe indiquant au moins un premier UE dans le groupe et un deuxième UE dans le groupe qui sont planifiés pour recevoir une transmission de données sur un canal de données de liaison descendante. La station de base (gNB) transmet (103) une première transmission de données au premier UE et une deuxième transmission de données au deuxième UE conformément aux DCI de groupe sur le canal de données de liaison descendante. La première transmission de données et la deuxième transmission de données sont multiplexées spatialement.
