Abstract: Embodiments are provided for supporting variable sub-carrier spacing and symbol duration for transmitting OFDM or other waveform symbols and associated cyclic prefixes. The symbol duration includes the useful symbol length and its associated cyclic prefix length. The variable sub-carrier spacing and symbol duration is determined via parameters indicating the sub-carrier spacing, useful symbol length, and cyclic prefix length. An embodiment method, by a network or a network controller, includes establishing a plurality of multiple access block (MAB) types defining different combinations of sub-carrier spacing and symbol duration for waveform transmissions. The method further includes partitioning a frequency and time plane of a carrier spectrum band into a plurality of MAB regions comprising frequency-time slots for the waveform transmissions. The MAB types are then selected for the MAB regions, wherein one MAB type is assigned to one corresponding MAB region.

Abstract: Assigning traffic to be transported over either the primary band or the complementary band of a unified air interface based on quality of service (QoS) constraints of the traffic may allow for improved network resource utilization efficiency. In one example, traffic having deterministic QoS constraints is assigned to the primary band, while traffic having statistical QoS constraints is assigned to the complementary band when the complementary band is capable of satisfying the statistical QoS constraints of the traffic. If a condition on the complementary band prevents it from satisfying the statistical QoS constraint of the traffic, then the traffic is assigned to the primary band.

Abstract: Performing wireless transmissions over a unified air interface that span portions of both the primary band and the complementary band may provide improved throughput and spectral efficiency in next generation networks. Wireless transmissions spanning both the licensed and unlicensed spectrum carry data in different frame formats over the respective primary and complementary bands. For example, frames communicated over the primary band may have a different channel structure (e.g., different size, placement, orientation, etc.) than frames communicated over the complementary band. Wireless transmissions spanning the licensed and unlicensed spectrum may also utilize different access schemes and/or waveforms over the respective primary and complementary bands. Embodiment unified air interfaces may be dynamically configurable via software defined radio (SDR) signaling instructions.

Abstract: Data heterogeneity has been shown to reduce the convergence speed and model accuracy in existing federated learning (FL) and distributed learning (DL) based artificial intelligence or machine learning (AI/ML) model training processes. In some embodiments, a group of devices participating in an FL or DL based AI/ML model training process is divided into clusters, e.g., based on similarities in their data class distributions, and each device is configured with a cascaded AI/ML model that includes a first AI/ML sub-model and a second AI/ML sub-model that are cascaded. For each device, one of the cascaded sub-models is a common AI/ML sub-model that is common to all devices in the group, and the other sub-model is a cluster-specific AI/ML sub-model that is common to the cluster that the device has been assigned to within the group of devices. A multi-stage training process for the cascaded AI/ML model is also provided.

Abstract: Systems and methods of reporting wireless channel state information are provided. With the provided system and method, in a situation where there are multiple UEs which are close to each other, such that channel conditions may be similar for the multiple UEs, one of the UEs is configured to report interference information on a time pattern that has at least two measurement time durations for which interference is to be measured, for example, only for a subset of N consecutive measurement time durations. Other UEs may be configured to report interference information for different time patterns, for example different subsets of the N time slots.
