Title (EN) CHANNEL STATE INFORMATION ACQUISITION IN A WIRELESS COMMUNICATION SYSTEM
(FR) ACQUISITION D’INFORMATIONS D’ÉTAT DE CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract:
(EN) This invention presents a method for uplink SRS transmission in MU-MIMO wireless communication systems comprising the BS reserving resources for SRS transmission and multiplexing the reserved resources among neighboring cells and among multiple UEs allocated to the same SRS transmission resource; the BS estimating the CQI of each UE through the uplink channel; and the BS allocating the same resource to a group of UEs to transmit uplink SRSs based on the estimated CQI and the QoS requirement.
(FR) La présente invention concerne un procédé pour une émission de signal de référence de sondage (SRS) de liaison montante dans des systèmes de communication sans fil à entrées multiples, sorties multiples (MIMO) multi-utilisateurs (MU) comprenant les opérations suivantes : la station de base (BS) réserve des ressources pour une émission de SRS et effectue un multiplexage des ressources réservées parmi des cellules voisines et parmi de multiples équipements utilisateur (UE) attribués à la même ressource d’émission de SRS ; la BS estime l'indicateur de qualité de canal (CQI) de chaque UE par l’intermédiaire du canal de liaison montante ; et la BS attribue la même ressource à un groupe d’UE pour émettre des SRS de liaison montante sur la base du CQI estimé et de l’exigence de qualité de service (QoS).
