Title (EN) COMMUNICATION DEVICES FOR MULTIPLE GROUP COMMUNICATIONS
(FR) DISPOSITIF DE COMMUNICATION POUR LES COMMUNICATIONS EN GROUPES MULTIPLES
Abstract:
(EN) A base station for communicating with multiple groups of wireless communication devices is described. The base station includes a processor and executable instructions stored in memory that is in electronic communication with the processor. The base station determines a number of wireless communication devices. The base station also splits the number of wireless communication devices into groups. The base station further determines a precoding matrix for each group. The base station additionally transmits a beamformed signal to each group using the precoding matrix for each group.
(FR) L'invention concerne une station de base servant à communiquer avec une pluralité de groupes de dispositifs de communication sans fil. La station de base comprend un processeur et des instructions exécutables stockées dans une mémoire qui est en communication électronique avec le processeur. La station de base détermine un certain nombre de dispositifs de communication sans fil. La station de base répartit également ces dispositifs de communication sans fil en groupes. La station de base détermine également une matrice de précodage pour chaque groupe. La station de base envoie en outre à chaque groupe un signal formé en faisceau, en utilisant la matrice de précodage de chaque groupe.
