Abstract
(EN) A method includes selecting a subset k of N accessible antennas to use to process a transmission received at the N antennas and sent by a user equipment, and processing the transmission from the user equipment at least by using baseband information from the k antennas. An apparatus includes one or more processors and one or more memories including computer program code. The one or more memories and the computer program code are configured to, with the one or more processors, cause the apparatus to perform at least the following: selecting a subset k of N accessible antennas to use to process a transmission received at the N antennas and sent by a user equipment; and processing the transmission from the user equipment at least by using baseband information from the k antennas. Additional apparatus, computer programs, and computer program products are disclosed.
(FR) L'invention concerne un procédé consistant à sélectionner un sous-ensemble k de N antennes accessibles à utiliser pour traiter une transmission reçue au niveau des N antennes et envoyée par un équipement utilisateur, et pour traiter la transmission provenant de l'équipement utilisateur au moins à l'aide d'informations de bande de base provenant des antennes k. L'invention concerne également un appareil comprenant au moins un processeur et au moins une mémoire comprenant un code de programme informatique. Ladite au moins une mémoire et le code de programme informatique sont conçus, avec ledit au moins un processeur, pour susciter la réalisation par l'appareil d'au moins les étapes suivantes : sélectionner un sous-ensemble k de N antennes disponibles devant être utilisé pour traiter une transmission reçue au niveau des N antennes et envoyée par un équipement utilisateur; et traiter la transmission provenant de l'équipement utilisateur au moins à l'aide d'informations de bande de base provenant des antennes k. Un appareil additionnel, des programmes informatiques et des produits de programmes informatiques sont également décrits.
