Title (EN) CODEBOOK SUBSET RESTRICTION DESIGN FOR MIMO
(FR) CONCEPTION DE RESTRICTION DE SOUS-ENSEMBLE DE LIVRE DE CODES POUR MIMO
Abstract:
(EN) Aspects of the present disclosure relate to techniques for codebook subset restriction (CSR). In some cases, a user equipment (UE) receives, from a network entity, codebook subset restriction (CSR) information. The UE determines, based on the CSR information, a restricted beam set for a plurality of antenna panels, determines precoding matrix indicator (PMI) feedback for the antenna panels subject to restricted beam set, and provides the PMI feedback to the network entity.
(FR) Des aspects de la présente invention concernent des techniques pour une restriction de sous-ensemble de livre de codes (CSR). Dans certains cas, un équipement d'utilisateur (UE) reçoit, en provenance d'une entité de réseau, des informations de restriction de sous-ensemble de livre de codes (CSR). L'UE détermine, sur la base des informations de CSR, un ensemble restreint de faisceaux pour une pluralité de panneaux d'antenne, détermine des informations en retour d'indicateur de matrice de précodage (PMI) pour les panneaux d'antenne soumis à l'ensemble restreint de faisceaux, et fournit les informations en retour de PMI à l'entité de réseau.
