1. A method of facilitating a cell search process in a wireless communication network that transmits synchronization signals to allow user equipment to synchronize with cells and transmits reference signals to allow user equipment to detect cell identities, the method comprising: defining a set of synchronization signal sequences to be used for generating individual ones of the synchronization signals; defining a set of reference signal sequences to be used for generating individual ones of the reference signals; and linking the synchronization signal sequences to the reference signal sequences according to a defined mapping to thereby enable user equipment to determine cell identities based on mapping detected synchronization signal sequences to corresponding reference signal sequences according to the defined mapping.
