Systems and techniques are provided for wireless communications. For example, a process can include receiving, from a first network entity a request to identify one or more additional network entities available for communication with a wireless communication device. A process can include transmitting, to a second network entity included in the one or more additional network entities, timing information indicative of a difference between first synchronization information associated with the first network entity and second synchronization information associated with the second network entity. A process can include receiving, from the second network entity, subframe allocation information corresponding to periodic advertisements (PAs) between the second network entity and the wireless communication device. A process can include receiving, from the second network entity, a PA based on the subframe allocation information.
