Abstract

L'invention concerne un procédé mis en œuvre par un nœud de réseau (1610A, 1610B, 1800, 2002, 2104) pour déterminer une attribution de bloc de ressources en vue de planifier un équipement utilisateur, UE, (1612A, 1612B, 1612C, 1612D, 1700, 2002, 2106) dans une communication en liaison montante, le procédé consistant à déterminer (601) une classe de puissance d'UE d'un UE. Le procédé consiste en outre à déterminer (603) un emplacement d'UE de l'UE. Le procédé consiste en outre à déterminer (605) un type de schéma d'accès multiple, MAS, pour l'UE. Le procédé consiste en outre à déterminer (607) une attribution de bloc de ressources pour l'UE sur la base de la classe de puissance d'UE, de l'emplacement d'UE et du type de MAS pour l'UE. Le procédé consiste en outre à attribuer (609) le bloc de ressources pour l'UE. En outre, ou en variante, une disponibilité de bloc de ressources est connue et le type de MAS pour l'UE est déterminé sur la base de la classe de puissance d'UE, de l'emplacement d'UE et des blocs de ressources disponibles.
