(FR) DISPOSITIF DE COMMANDE, NŒUD DE RÉSEAU ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) The invention relates to a control device and a network node comprising such a control device (100). The control device (100) comprises a processor (102) configured to: a) obtain at least one pilot signal (410n) associated with a user device (400); b) compute an uplink channel estimation (GUL) based on the at least one pilot signal (410n); c) compute an uplink detector (UUL) based on the complex conjugate of the uplink channel estimation (GUL) and a current uplink transmit power allocation (PULcurrent), d) derive uplink Signal-to-lnterference and Noise Ratios, SINRs, based on the complex conjugate of the channel estimation (GUL), e) compute a new uplink transmit power allocation (PULnew) by taking the ratio of the current uplink transmit power allocation (PULcurrent) to the uplink SINRs; compute a downlink precoder (UDL) based on the uplink detector (UUL). Furthermore, the invention also relates to corresponding methods, a wireless communication system, a computer program, and a computer program product.
(FR) L'invention porte un dispositif de commande et sur un nœud de réseau comprenant un tel dispositif de commande (100). Le dispositif de commande (100) comprend un processeur (102) configuré pour : a) obtenir au moins un signal pilote (41 On) associé à un dispositif utilisateur (400) ; b) calculer une estimation de canal de liaison montante (GUL) sur la base du ou des signaux pilotes (41 On) ; c) calculer un détecteur de liaison montante (UUL) sur la base du conjugué complexe de l'estimation de canal de liaison montante (GUL) et d'une attribution de puissance d'émission de liaison montante courante (P ULcurrent ), d) trouver des rapports signal sur brouillage plus bruit, SINR, de liaison montante sur la base du conjugué complexe de l'estimation de canal (GUL), e) calculer une nouvelle attribution de puissance d'émission de liaison montante (P ULnew ) par prise du rapport de l'attribution de puissance d'émission de liaison montante courante (P ULcurrent ) sur les SINR de liaison montante ; calculer un précodeur de liaison descendante (UDL) sur la base du détecteur de liaison montante (UUL). En outre, l’invention porte également sur des procédés correspondants, sur un système de communication sans fil, sur un programme informatique et sur un produit-programme informatique.
