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： 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 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： Systems and methods of scheduling grant-based traffic and mapping resources for grant-free traffic are provided. Grant-based traffic is scheduled in a first frequency partition, and grant-free traffic is mapped in a second frequency partition. In a first option, grant-based traffic is also scheduled in part of the first partition, but in a limited manner that ensures a given device's transmission and retransmissions do not all experience interference with the grant-based traffic. In another option, some grant-free traffic is mapped to part of the second partition and is spread in frequency across the second partition.

摘要： Methods and systems are provided for allocating resources including VoIP (voice over Internet Protocol) and Non-VoIP resources. In some embodiments, multiplexing schemes are provided for use with OFDMA (orthogonal frequency division multiplexing access) systems, for example for use in transmitting VoIP traffic. In some embodiments, various HARQ (Hybrid Automatic request) techniques are provided for use with OFDMA systems. In various embodiments, there are provided methods and systems for dealing with issues such as Handling non-full rate vocoder frames, VoIP packet jitter handling, VoIP capacity increasing schemes, persistent and non-persistent assignment of resources in OFDMA systems.

摘要： Systems and methods are provided that facilitate multiple switching points within a slot. A slot format indication is conveyed to a user equipment which indicates which symbols within a slot are uplink, downlink or unknown. Some formats feature half-slot switching meaning that a switch from uplink to downlink transmission takes place twice within a slot. Switching on a more frequent basis can deliver improved latency.
