Methods and apparatus for a wireless communication network. A method performed by a base station comprises determining a set of transmission resources, out of a number of sets of transmission resources, based on a property associated with a synchronization signal of the base station. The synchronization signal is one or more of: a Primary Synchronization Signal, PSS; a Secondary Synchronization Signal, SSS; and an Enhanced Synchronization Signal, ESS. The mthod further comprises transmitting the synchronization signal and/or system information in the determined set of transmission resources. The property relates to at least one of: a symbol sequence comprised in the synchronization signal; a scrambling code used on the synchronization signal; and a transmission resource used for transmission of the synchronization signal.
