A communication method and device are provided. They are used in mobile communication system of LTE Type2 TDD. The method includes: a first communication apparatus sends radio frames to a second communication apparatus, every half-frame of the radio frame comprises a data time slot and a Downlink Pilot Time Slot, the data time slot is used to transmit data. The Downlink Pilot Time Slot is used to carry the synchronizing information. And the data time slot is shorter than the original data time slot about a first time slot.

La présente invention concerne un procédé et un dispositif de communication utilisés dans un système de communications mobiles LTE TDD de type 2. Le procédé comprend: la transmission par un premier appareil de communication de trames radio vers un second appareil de communication, chaque demi-trame de la trame radio comportant un intervalle de temps de données, et un intervalle de temps de symboles pilotes de liaison descendante, l'intervalle de temps de données étant utilisé pour transmettre des données. L'intervalle de temps de symboles pilotes de liaison descendante est utilisé pour transporter l'information de synchronisation. L'intervalle de temps de données est plus court que l'intervalle de temps de données d'origine d'environ un premier intervalle de temps.
