CA 2668247

A method and apparatus for processing feedback implemented in a wireless transmit/receive unit (WTRU) comprises estimating a channel matrix. The effective channel is calculated and a precoding matrix is selected. Feedback bits are generated and transmitted. The feedback bits relate to non-differential or differential feedback or a combination thereof, or the feedback is a binary sign bit alone or in combination with non-differential feedback.

L'invention concerne un procédé et un appareil de traitement de la rétroaction mis en oeuvre dans une unité d'émission/réception sans fil (WTRU) consistant à évaluer une matrice de canal. Le canal effectif est calculé et une matrice de précodage est sélectionnée. Des bits de rétroaction sont générés et transmis.
