Patent

CA 2248515

The invention relates to mobile cellular communication systems in which asymmetric access to a time division duplex (TDD) communication channel is provided. The channel is divided (by TDD) into slots which are allocated to either uplink communication or downlink communication by the base station in each cell. Timing of slots, and thus of compulsory uplink and downlink slots, is co-ordinated across the cells of a system.

L'invention porte sur des systèmes de communication mobiles cellulaires offrant l'accès asymétrique à un canal de communication à duplexage par répartition dans le temps. Le canal est divisé (par duplexage par répartition dans le temps) en créneaux qui sont attribués soit à la communication de liaison montante, soit à la communication de liaison descendante par la station de base de chaque cellule. La synchronisation des créneaux, et par conséquent des créneaux de liaison ascendante et de liaison descendante, est coordonnée pour l'ensemble des cellules d'un système.
