摘要： Systems and methods related to a synchronization signal (18) suited for wireless devices (22) in an extended coverage area (16) of a cell (14) of a cellular communications network (10) are disclosed. In embodiments, a base station (12) transmits a synchronization signal (18) including multiple repetitions of a basic synchronization block during a coherence time of a downlink channel over which the synchronization signal (18) is transmitted. The multiple repetitions of the basic synchronization block during the coherence time enable coherent combining during detection of the synchronization signal (18) at wireless devices (22) located in the cellular communications network (10). This coherent combining enables, for example, wireless devices (22) located in an extended coverage area (16) of a cell (14) served by the base station (12) to synchronize to the cell (14) using a shorter synchronization signal (18) than would be required if only non-coherent combining were used.

摘要： An arrangement for controlling energy consumption of a network node associated with a cell includes a terminal activity monitor (16) configured to detect active terminals served by the cell. A transmission controller (18) is connected to the terminal activity monitor and is configured to restrict transmission downlink in the cell during time periods when there are no active terminals served by the cell. During these time periods transmission is restricted to intermittent transmission of information assisting active terminals not served by the cell in finding the cell.
