A network node for a wireless communication system includes a processor and a transceiver, the processor being configured to generate a set of at least two synchronization signal sequences; construct a synchronization signal for each synchronization signal sequence to create a set of synchronization signals, such that each of the synchronization signals in the set of synchronization signals has an auto correlation and cross correlation below a threshold value with any other synchronization signal in the set of synchronization signals; generate a set of directional beam patterns, wherein each beam pattern in the set of directional beam patterns corresponds to one of the synchronization signals in the set of synchronization signals; and wherein the transceiver is configured to transmit the synchronization signals in the set of synchronization signals using the beam pattern for each synchronization signal over a same time frequency resource.
