Abstract: front page image
(EN)To supply a method for control channel inter-cell interference avoiding and a base station so that inter-cell interference is avoided and the lowest demodulation threshold of the control channel is reduced, is the technical problem to be solved by the present invention. The method includes that the base station executes the following steps: classifying the terminals in each cell, wherein edge terminal is included; determining time domain locations for sending down control channels corresponding to the scheduling of each type of terminals, and enabling the time domain locations for sending down the control channels, which are corresponding to the scheduling of edge terminals in adjacent cells, to be separated; and according to the determined time domain locations, sending down the control channels corresponding to the scheduling of each type of terminals, wherein the control channel corresponding to the scheduling of edge terminals is sent down with power greater than that of other types of terminals.
(FR)L'invention concerne un procédé permettant d'éviter le brouillage intercellulaire du canal de commande et une station de base permettant d'éviter le brouillage intercellulaire et de réduire le seuil de démodulation le plus bas du canal de commande. Le procédé consiste à faire en sorte que la station de base exécute les étapes suivantes : classer les terminaux dans chaque cellule, y compris un terminal de bord ; déterminer des positions dans le domaine temporel pour l'envoi de canaux de commande correspondant à la planification de chaque type de terminal, et permettre la séparation des positions dans le domaine temporel auxquelles les canaux de commande sont envoyés en sens descendant, ces positions correspondant à la planification de terminaux de bord dans des cellules adjacentes ; et, selon les positions déterminées dans le domaine temporel, envoyer en sens descendant les canaux de commande correspondant à la planification de chaque type de terminal, le canal de commande correspondant à la planification de terminaux de bord étant envoyé en sens descendant avec une puissance supérieure à celle d'autres types de terminaux.
