Título (EN) UPLINK POWER CONTROL FOR INTERFERENCE MITIGATION IN FULL- DUPLEX CELLULAR NETWORKS
(FR) COMMANDE DE PUISSANCE DE LIAISON MONTANTE POUR LIMITATION DE BROUILLAGE DANS DES RÉSEAUX CELLULAIRES DE TYPE DUPLEX INTÉGRAL
Resumo:
(EN) Technology described herein relates to technologies for open-loop power control (OLPC) for Full-Duplex (FD) systems that takes UE-to-UE interference and eNB-to-eNB interference into account. Technology is provided whereby a trade-off between UL and DL performance is characterized as a function of a transmit power setting. Technology is provided to mitigate UE-to-UE interference and eNB-to-eNB interference in FD systems. In addition, technology is provided to identify a power setting that will substantially maximize a sum spectral efficiency (SE). In addition, different neighboring cells can set different target power levels based on current interference conditions and current uplink/downlink conditions in each cell.
(FR) La technologie décrite ici concerne des technologies de commande de puissance en boucle ouverte (OLPC, Open-Loop Power Control) pour des systèmes de type duplex intégral (FD, Full Duplex) prenant en compte le brouillage d'équipement utilisateur (UE, User Equipment) à UE et le brouillage d'un nœud B évolué (eNB, Evolved Node B) à un eNB. Une technologie est fournie moyennant quoi un compromis entre performance montante (UL, uplink) et descendante (DL, downlink) est caractérisé en fonction d'un réglage de puissance de transmission. L'invention concerne une technologie pour atténuer le brouillage d'UE à UE et le brouillage d'eNB à eNB dans des systèmes FD. De plus, une technologie est fournie pour identifier un réglage de puissance qui permet de maximiser sensiblement la somme de l'efficacité spectrale (SE, Spectral Efficiency) De plus, des cellules voisines différentes peuvent régler différents niveaux de puissance cibles sur la base des conditions de brouillage actuelles et de conditions de liaison montante/liaison descendante actuelles dans chaque cellule.
