Abstract: A method embodiment includes implementing, by a base station (BS), a grant-free uplink transmission scheme. The grant-free uplink transmission scheme defines a first contention transmission unit (CTU) access region in a time-frequency domain, defines a plurality of CTUs, defines a default CTU mapping scheme by mapping at least some of the plurality of CTUs to the first CTU access region, and defines a default user equipment (UE) mapping scheme by defining rules for mapping a plurality of UEs to the plurality of CTUs.

Abstract: Systems, methods, and apparatuses for providing waveform adaptation are provided. In an example, a method is provided for identifying a plurality of candidate waveforms, and selecting one of the candidate waveforms for data transmission. The candidate waveforms may be identified in accordance with one or more criteria, such as a transmission capability of the transmitting device, a reception capability of the receiving device, a desired Peak-to-Average-Power-Ratio (PAPR) characteristic, adjacent channel interference (ACI) rejection requirements, spectrum localization requirements, and other criteria. The waveform selected for data transmission may be selected in accordance with one or more waveform selection criteria, such as traffic characteristic, application types, etc.

Abstract: Methods and devices are provided for communicating data in a wireless channel. In one example, a method includes adapting the transmission time interval (TTI) length of transport container for transmitting data in accordance with a criteria. The criteria may include (but is not limited to) a latency requirement of the data, a buffer size associated with the data, a mobility characteristic of a device that will receive the data. The TTI lengths may be manipulated for a variety of reasons, such as for reducing overhead, satisfy quality of service (QoS) requirements, maximize network throughput, etc. In some embodiments, TTIs having different TTI lengths may be carried in a common radio frame. In other embodiments, the wireless channel may partitioned into multiple bands each of which carrying (exclusively or otherwise) TTIs having a certain TTI length.
