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.

Abstract: Wireless communications systems and methods related to decoupling uplink latency using common uplink (UL) burst in Time Division Duplex (TDD) sub-frame structure are disclosed. User equipment (UE) can transmit to a base station a common UL burst in each sub-frame communicated between UE and the base station, wherein he common UL burst comprises at least one of: a physical layer (PHY) acknowledgement (ACK), a scheduling request (SR), a buffer status report (BSR), or a sounding reference signal (SRS). UE can be further configured to transmit scheduled UL payload data in at least one common UL burst of at least one sub-frame communicated between the UE and the base station.
