Title
(EN) A METHOD FOR TRANSMITTING INFORMATION IN A MULTIPLE ANTENNA SYSTEM
(FR) PROCEDE D'EMISSION D'INFORMATIONS DANS UN SYSTEME A ANTENNES MULTIPLES
Abstract
(EN)
A method of transmitting and receiving information in a wireless mobile communication system where a mobile station (MS) has at least one antenna is disclosed. More specifically, the method discloses transmitting information to a base station (BS). Here, the information includes the number of antennas to be used for transmission by the MS and whether the MS supports a collaborative spatial multiplexing (SM) scheme. Furthermore, the method discloses receiving information from the BS. Here, the information includes the number of antennas that can be used by the MS for transmission and a multi-input multi-output (MIMO) matrix to be used by each antenna of the MS.

L'invention concerne un procédé d'émission et de réception d'informations dans un système de communications mobiles sans fil où une station mobile (MS) possède au moins une antenne. Plus spécifiquement, le procédé comporte l'émission d'informations vers une station de base (BS). Ici, les informations comprennent le nombre d'antennes à utiliser pour l'émission par la MS et le fait que la MS prenne en charge ou non un schéma collaboratif de multiplexage spatial (SM). En outre, le procédé comporte la réception d'informations depuis la BS. Ici, les informations comprennent le nombre d'antennes utilisables par la MS pour l'émission et une matrice à entrées et sorties multiples (multi-input, multi-output : MIMO) à utiliser par chaque antenne de la MS.
