Title
(EN) ASSIGNING CELL AND RESOURCE BLOCKS BY OPTIMIZING INTERFERENCE
(FR) PROCÉDÉ ET APPAREIL DE COMMUNICATION SANS FIL PERMETTANT D'ATTRIBUER UNE CELLULE ET DES BLOCS DE RESSOURCES
Abstract
(EN)
A method and apparatus for assigning a cell and resource blocks (e.g. subcarriers, timeslots, orthogonal codes, etc.) to a wireless transmit/receive unit (WTRU) in a wireless communication system including a resource management unit and a plurality of cells having resource blocks are disclosed. The WTRU is currently associated with a particular one of the cells-. Path losses between the WTRU and cells neighboring the particular cell are determined. The average level of inter- cell interference on each resource block at each cell neighboring the particular cell is then determined. A signal -to -interference ratio (SIR) is then determined to support a guaranteed bit rate of the WTRU on an uplink.

La présente invention concerne un procédé et un appareil permettant d'attribuer une cellule et des blocs de ressources à des unités d'émission ou/et réception sans fil (WTRU) dans un système de communication sans fil comportant une unité de gestion de ressources et une pluralité de cellules dotées de blocs de ressources. Le procédé selon l'invention consiste, le WTRU étant actuellement associé à une cellule donnée parmi lesdites cellules : à déterminer l'affaiblissement de propagation entre le WTRU et les cellules voisines de la cellule donnée; puis à déterminer le niveau moyen d'interférence intercellulaire sur chaque bloc de ressources au niveau de chaque cellule voisine de la cellule donnée; et à déterminer ensuite un rapport signal sur interférence (SIR) permettant de prendre en charge un débit binaire garanti sur le WTRU sur une liaison montante.
