Title (EN) TECHNIQUES UTILIZING STEP SIZE ADAPTATION FOR DIFFERENTIAL BEAMFORMING IN WIRELESS NETWORKS
(FR) TECHNIQUES UTILISANT UNE ADAPTATION DE TAILLE PAR ÉTAPES POUR UNE FORMATION DE FAISCEAU DIFFÉRENTIELLE DANS DES RÉSEAUX SANS FIL
Abstract:
(EN) An embodiment of the present invention provides a method used in transmit beam forming, comprising, providing differential feedback by using variable differential codebooks across a plurality of feedbacks wherein the differential codebooks may have different shapes, and/or spans, and/or the numbers of codewords across feedbacks.
(FR) L'invention concerne, selon un mode de réalisation, un procédé utilisé dans la formation de faisceaux de transmission, consistant à utiliser une rétroaction différentielle par l'utilisation de listes de codage différentielles variables sur une pluralité de rétroactions, lesdites listes pouvant avoir des formes et/ou des étendues différentes, et/ou des nombres différents de mots codés sur les rétroactions.
