The present application relates to synchronization signal transmission using multiple beams. In an example, a network node may support M beams covering M areas. However, only K<M beams may be used at any time for transmission of synchronization signals. Accordingly, the network node cycles through the K beams allocated to synchronization signal transmission, whereby a synchronization signal is transmitted on K spatially-multiplexed and simultaneously-active beams to reach K coverage areas during a first time period, then next K coverage areas during a second time period, and so on until all of the M coverage areas are reached to restart the cycle. A UE is located in only one coverage area, and would see the synchronization signal beam once during a period of time equal to the time needed to cycle through the M coverage areas.
