Abstract

L'invention concerne des procédés et systèmes de commande de l'attribution de puissance d'éléments de ressource de messages de commande en liaison descendante transmis sur un canal de commande en liaison descendante dans un réseau de communication. Les procédés impliquent généralement l'ajustement du niveau de puissance des éléments de ressource transmis dans une partition des éléments de ressource, tout en n'ajustant généralement pas le niveau de puissance des éléments de ressource transmis dans une autre partition des éléments de ressource. En ajustant le niveau de puissance des éléments de ressource transmis dans seulement une des partitions, le rapport de signal à interférence et bruit (SINR) au niveau du terminal mobile auquel le message de commande en liaison descendante est transmis, peut être amélioré sans diminuer de façon significative ou autrement affecter de manière négative le SINR de terminaux mobiles situés dans des cellules adjacentes. De manière générale, les procédés permettent la réduction ou l'atténuation de l'interférence entre les cellules sur le canal de commande en liaison descendante.
