A system and method to optimize the number of uplink and downlink slots (12, 16), given the maximum number of crossed slots between any two cells (10, 14) is disclosed. The present invention effectively assigns a direction (i.e. uplink or downlink) to every slot (12, 16) in every cell (10, 14) of the system, taking into account the trade-off between: a) avoiding base-to-base or mobile-to-mobile interference; and b) matching the slot assignment of every cell as closely as possible to the local traffic conditions. The present invention assigns users to slots (12, 16) according to their transmission power requirements in order to allow conflicting slot-to-cell assignments between two cells (10, 14) in the same geographic region.
L'invention concerne un système et un procédé d'optimisation du nombre d'intervalles de liaison montante et descendante (12, 16), étant donné le nombre maximum d'intervalles croisés entre deux cellules (10, 14) quelconques. L'invention permet d'attribuer effectivement une direction (c'est à dire montante ou descendante) à chaque intervalle (12, 16) dans chacune des cellules (10, 14) du système, prenant en compte l'arbitrage entre a) éviter l'interférence de base à base ou de mobile à mobile, et b) faire correspondre l'attribution d'intervalle de chaque cellule (12, 16) aussi rapproché que possible concernant les conditions locales de trafic. L'invention attribue des intervalles (12, 16) aux utilisateurs en fonction de leurs besoins de puissance d'émission de façon à permettre des attributions conflictuelles intervalle à cellule entre deux cellules (10, 14) de la même région géographique.
