Abstract: 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.

Abstract: Embodiments are provided for uplink measurement based mechanism and control using user equipment (UE) centric sounding signals. The mechanism provides an alternative to DL-measurement dominated system control. Based on UL-measurements at TPs, the network obtains knowledge of users' channel and timing information, traffic, and interference, and is thus able to perform better control, including TP and UE clustering and optimization, and power control and link adaptation. In an embodiment method, a TP receives one-to-one mapping information indicating a plurality of UE IDs and a plurality of sounding channels assigned to the corresponding UE IDs. When the TP detects a sounding reference signal (SRS) from a UE, the TP is able to identify the UE using the detected SRS and the one-to-one mapping information. The TP then obtains measurement information for the identified UE, enabling better control and communications for uplink and downlink transmissions between multiple TPs and the UE.

Abstract: A base station may update a SoftAI profile to obtain an updated SoftAI profile specifying a new air interface configuration that was unknown to the base station prior to updating the SoftAI profile. The base station may receive SoftAI configuration information from a network controller, and update the SoftAI profile based on the SoftAI configuration information. The updated SoftAI profile may define a new combination of physical layer parameters, a new waveform, a new modulation coding scheme (MCS), or any other AI configuration parameter, or collection of AI configuration parameters. The SoftAI configuration information, or a separate network instruction, may also specify one or more conditions for using the new air interface configuration to communicate traffic over a wireless link between the base station and a wireless device.

Abstract: It is possible to reduce overhead when dynamically establishing an air interface configuration by communicating a modification instruction along with an index associated with a predefine air interface configuration. The modification instruction identifies a modification to one or more parameters of the predefined air interface configuration associated with the index. Together, the index and the modification indication specify a modified air interface configuration that is different than any of the candidate air interface configurations predefined for the network. The modification instruction allows networks to achieve similar degrees of flexibility while using substantially fewer predefined air interface configurations, which in turn permits the index associated with the selected air interface configuration to be signaled using fewer bits.
