A transmitting device may identify synchronization signals and a set of frequency hopping channels for communications as part of a discovery reference signal (DRS) in an anchor channel. The set of frequency hopping channels may include a sequence to indicate an order for utilizing each hopping channel of the set of hopping channels.

As such, each hopping channel may be utilized an equal number of times within a period of time and have an approximately equal occupancy time to the other hopping channels.
