Abstract
Wireless communications systems, methods, and techniques related to signaling and determining slot and mini-slot structures are provided. A first wireless communication device transmits a first signal according to a first numerology including at least a first tone spacing. The first signal indicates a second numerology including at least a second tone spacing. The first wireless communication device transmits a second signal according to the second numerology. The first signal includes a physical broadcast channel (PBCH) signal. The second numerology is independent from the first numerology. Different slot/mini-slot structures may be utilized for varying channel types to support mixed numerology arrangements. Embodiments may utilize single and varied slot structures; single slot structures may be decoupled from transmission numerology and varied slot structures may be defined based on reference numerology. Other aspects, embodiments, and features are also claimed and described.
