    摘要： Methods and systems are provided to allow signals for multiple service slices using sub-bands that are part of a system bandwidth. In some cases the signals for a given service slice are self-contained within the sub-band in the sense that channels for initial access and ongoing communications are all located within the sub-band. A receiver that is only accessing the given service slice need only be capable of receiving the sub-band. The method may involve, in a first sub-band predefined for a first service slice, transmitting first initial access information for a first service associated with the first service slice. The method further involves, in a second sub-band predefined for a second service slice, transmitting second initial access information for a second service associated with the second service slice. The second sub-band is different from the first sub-band.

    摘要： Methods and Devices that provide mechanisms for an air interface capability exchange are disclosed. The air interface capability exchange enables a user equipment device to signal its air interface configuration capabilities to a network device to facilitate software configurable air interface (SoftAI) optimization. The air interface capability exchange involves a UE device signaling information regarding an air interface configuration capability type of the device's air interface. The air interface configuration capability type identifies whether the device supports multiple air interface configurations of the air interface. The UE device may also transmit information regarding air interface configuration options that it supports. The network device may determine a configuration for the UE device's air interface based at least in part on the information provided by the UE device.

    摘要： A system and method includes implementing, by a base station (BS), a reliable ultra-low latency transmission mechanism in a grant-free uplink transmission scheme having defined therein contention transmission unit (CTU) access regions and a plurality of CTUs. Implementing the reliable ultra-low latency transmission mechanism includes defining a reliable ultra-low latency CTU (RULL-CTU) access region from a portion of the CTU access regions of the grant-free transmission scheme, defining an RULL-CTU mapping scheme by mapping at least a portion of plurality of CTUs to the RULL-CTU access region to define a plurality of RULL-CTUs, defining a reliable ultra-low latency user equipment (RULL-UE) mapping scheme by defining rules for mapping a plurality of RULL-UEs to the plurality of RULL-CTUs in an initial pattern for initial transmissions in a first transmission time interval (TTI), and a regrouped pattern for redundant transmissions in a second TTI subsequent to the first TTI.

    摘要： 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.
