Title (EN) A METHOD AND APPARATUS USING A BASE CODEBOOK STRUCTURE FOR BEAMFORMING
(FR) PROCÉDÉ ET APPAREIL UTILISANT UNE STRUCTURE DE LIVRE DE CODES DE BASE POUR LA FORMATION DE FAISCEAUX
Abstract:
(EN) Techniques for a precoding scheme for wireless communications are described. A method and apparatus may comprise a first device for a communications system to determine a beamforming structure for a closed loop transmit beamforming scheme using channel information, one or more scaling factors and one or more integers to represent a complex vector. The beamforming structure may include a codeword, a codebook and a codeword index. Other embodiments are described and claimed.
(FR) L'invention concerne un schéma de codage préalable pour des communications sans fil. Un procédé et un appareil peuvent comporter un premier dispositif pour un système de communications afin de déterminer une structure de formation de faisceau pour un schéma de formation de faisceaux de transmission en boucle fermée à l'aide d'informations de canal, d'un ou de plusieurs facteurs d'échelle et d'un ou plusieurs nombres entiers afin de représenter un vecteur complexe. La structure de formation de faisceaux peut inclure un mot de code, un livre de codes et un index de mots de code. L'invention concerne également d'autres modes de réalisation.
