Title
(EN) METHOD OF DETERMINING DOPPLER FREQUENCY TRANSMISSION BEAM IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
(FR) PROCÉDÉ POUR DÉTERMINER UN FAISCEAU D'ÉMISSION DE FRÉQUENCE DOPPLER DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL ASSOCIÉ
Abstract
(EN)
A method of transmitting a signal, which is transmitted by a transmitting end in a wireless communication system, is disclosed in the present specification. Specifically, the method includes the steps of receiving Doppler information on a plurality of transmission beams from a receiving end; selecting a beam combination using the received Doppler information, wherein the beam combination is selected from a plurality of beam combinations depending on effective Doppler spread values of the beam combinations, wherein each of the beam combinations consists of two or more transmission beams among the plurality of transmission beams; and transmitting the signal to the receiving end using at least one transmission beam included in the selected beam combination.

La présente invention concerne un procédé d'émission d'un signal, qui est émis par une extrémité d'émission dans un système de communication sans fil. De manière spécifique, le procédé comprend les étapes consistant à recevoir des informations Doppler sur une pluralité de faisceaux d'émission à partir d'une extrémité de réception; à sélectionner une combinaison de faisceaux à l'aide des informations Doppler reçues, la combinaison de faisceaux étant sélectionnée parmi une pluralité de combinaisons de faisceaux en fonction de valeurs d'étalement Doppler effectives des combinaisons de faisceaux, chacune des combinaisons de faisceaux comprenant au moins deux faisceaux d'émission parmi la pluralité de faisceaux d'émission; et à émettre le signal à destination de l'extrémité de réception à l'aide d'au moins un faisceau d'émission inclus dans la combinaison de faisceaux sélectionnée.
