Design of signal synchronization for wireless devices in a mode of long reach extension

摘要

1 / 1 Summary "project of sync signal for wireless devices in a mode of extension of long range" systems and methods related to a sync signal (18) is particularly well suited to wireless devices (22) in a wide coverage area (16) of a cu00e9l Ula (14) in a cellular communications network (10) are disclosed.In one method, a base station (12) transmits a synchronization signal (18) that includes multiple repetitions of a basic block synchronization during a time of consistency of a downlink channel on which the sync signal (18) is transmitted.The multiple repetitions of the basic block synchronization during the time of coherence allows a coherent combination during the detection of the sync signal (18) in the wireless devices (22) located in the mobile communications network (10).This combination of coherent makes it possible, for example, wireless devices (22) located in a coverage area wide (16) of a cell (14) served by the base station (12) to synchronize the cell (14) by using a sync signal (18) shorter than what would be required If only non coherent combination were used.
