Title (EN) METHODS AND APPARATUS FOR ACQUIRING CHANNEL STATE INFORMATION WITH CHANNEL RECIPROCITY
(FR) PROCÉDÉS ET APPAREIL D'ACQUISITION D'INFORMATIONS D'ÉTAT DE CANAL ASSOCIÉS À LA RÉCIPROCITÉ DE CANAL
Abstract:
(EN) The techniques described herein relate to methods, apparatus, and computer readable media configured to provide for wireless techniques related to channel reciprocity. A channel estimation process between a mobile device and a base station is configured. The channel estimation process includes estimating a set of channel characteristics for an uplink direction of the wireless communication channel based on signals transmitted by the mobile device over the first set of antennas, and receiving a report associated with a set of channel characteristics for a downlink direction of the wireless communication channel from the mobile device, wherein the mobile device generates the report based on the estimated set of channel characteristics for the downlink direction of the wireless communication channel corresponding to the first set of antennas.
(FR) La présente invention concerne des techniques associées à des procédés, un appareil et des supports lisibles par ordinateur, configurés pour fournir des techniques sans fil associées à la réciprocité de canal. Un processus d'estimation de canal entre un dispositif mobile et une station de base est configuré. Le processus d'estimation de canal consiste à estimer un ensemble de caractéristiques de canal pour une direction de liaison montante du canal de communication sans fil sur la base de signaux transmis par le dispositif mobile sur un premier ensemble d'antennes, et à recevoir du dispositif mobile un rapport associé à un ensemble de caractéristiques de canal pour une direction de liaison descendante du canal de communication sans fil, le dispositif mobile générant le rapport sur la base de l'ensemble estimé de caractéristiques de canal pour la direction de liaison descendante du canal de communication sans fil correspondant au premier ensemble d'antennes.
