Patent ID: 8649365

Claim:
An apparatus, comprising: a receiver unit configured to receive a first synchronization signal, wherein the first synchronization signal has a first operating bandwidth corresponding in size to at least an operating bandwidth of the receiver unit that is a predetermined portion of an operating bandwidth of a network; a synchronization unit configured to provide initial synchronization with the network, wherein the receiver unit is further configured to receive a second synchronization signal, wherein the second synchronization signal has a second operating bandwidth that is outside the first operating bandwidth of the first synchronization signal, wherein the second synchronization signal is provided in a different sequence than the first synchronization signal in a frequency domain, so that the second synchronization signal is not detected during the initial synchronization, wherein the second synchronization signal is configured to depend upon an expected number of narrowband mobile stations, and wherein the apparatus is further configured to perform neighbor cell identification based at least on the second synchronization signal.
