Methods, systems, and devices are described for wireless communication. The method may include determining, at a wireless device, a logical identifier (ID) as a pseudo-random function of a physical device ID of the wireless device and a synchronization channel index, where the synchronization channel index corresponds to an instance of a periodically repeating synchronization channel in a radio frame. The wireless device may be a base station in a serving cell, such that the synchronization channel may be to synchronize a downlink to communicate with a user equipment (UE) operating in a narrow-band cellular internet of things. The method may also include generating a secondary synchronization signal (SSS) for each instance of the periodically repeating synchronization channel in the frame based at least in part on the logical ID and the corresponding synchronization channel index, and transmitting the frame from the wireless device. |
