Abstract
(EN)
A method for estimating a channel in a wireless communication system in which a plurality of terminals and a base station communicate with each other, according to one embodiment of the present invention, comprises the steps of: receiving reference signals transmitted through a plurality of slots; and estimating a channel by using the reference signals. Here, for the channel estimation, the number of reference signals received through at least one slot among the plurality of slots is different from the number of reference signals received through the other slots.
(FR)
L'invention concerne un procédé d'estimation de canal dans un système de communication sans fil dans lequel une pluralité de terminaux et une station de base communiquent ensemble, comportant dans un mode de réalisation les étapes consistant à: recevoir des signaux de référence transmis par l'intermédiaire d'une pluralité de fenêtres et à estimer un canal au moyen desdits signaux de référence. Ici, pour l'estimation de canal, le nombre de signaux de référence reçus par l'intermédiaire d'au moins une fenêtre parmi la pluralité de fenêtres est différent du nombre de signaux de référence reçus par l'intermédiaire des autres fenêtres.
