Title (EN) SCHEDULING OF USERS FOR MULTI-USER TRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM
(FR) PLANIFICATION D'UTILISATEURS EN VUE D'UNE TRANSMISSION À UTILISATEURS MULTIPLES DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract:
(EN) There is provided a method and corresponding arrangements for scheduling users with different Guard Interval, GI, length for multi-user transmission in a wireless communication system, where each of the users is associated with a GI length. The proposed technology involves grouping at least a subset of the users into at least two groups according to GI length for transmission in allocated transmission opportunity, TXOP, resources. In this way, by dynamically scheduling at least part of the users for group-wise transmission according to GI length, the spectral efficiency can be improved. The proposed technology allows for higher scheduling flexibility when different users have different GI length requirements.
(FR) L'invention concerne un procédé et des dispositifs correspondants permettant de planifier des utilisateurs ayant une longueur d'intervalle de garde GI différente en vue d'une transmission à utilisateurs multiples dans un système de communication sans fil, chacun des utilisateurs étant associé à une longueur de GI. La technique proposée consiste à regrouper au moins un sous-ensemble des utilisateurs en au moins deux groupes en fonction de la longueur de GI en vue d'une transmission dans des ressources attribuées d'opportunité de transmission TXOP. La planification dynamique d'au moins une partie des utilisateurs en vue d'une transmission par groupe en fonction de la longueur de GI permet donc d'améliorer l'efficacité spectrale. La technique proposée permet une plus grande flexibilité de planification lorsque différents utilisateurs ont différentes exigences de longueur de GI.
