Abstract

Des aspects de la présente invention concernent une paire de dispositifs de communication sans fil communiquant de façon sans fil avec un système de réseau d'une manière coordonnée. Les dispositifs de communication sans fil de la paire peuvent être en communication l'un avec l'autre par l'intermédiaire d'une liaison poste à poste sans fil. Un dispositif de communication sans fil primaire peut communiquer une première partie d'une transmission à entrées multiples et sorties multiples (MIMO) par l'intermédiaire de communications cellulaires et une seconde partie de la transmission MIMO par l'intermédiaire de la liaison poste à poste, ceci peut permettre au dispositif de communication sans fil principal de communiquer avec le système de réseau à un débit de données supérieur et/ou à un rang MIMO plus élevé.
