Abstract: A reliable wireless communication system needs good wireless signal detection and interference management. Traditional thinking for interference management mostly relies on interference cancellation or receiver design. In such a design, an interference issue occurs when a receiver is incapable of handling it. Various interference management embodiments are presented in the disclosure. Using HARQ retransmission incorporated with parameter changes, interference management may be improved through interference source control for more effective signal detection and interference management. Additionally, early termination parameters for decoding operation may be learned and implemented separately or jointly with HARQ retransmission. Furthermore, estimated interference power may be improved using machine-learning algorithm based on decoding statistics of the decoder.

Abstract: In a grant based system, a user equipment (UE) sends data in an uplink in a request-grant process. The UE first sending a scheduling request, a gNodeB processing the request and scheduling a grant sometime in future, then UE then either sending data if the grant is sufficient or requesting for another grant with more capacity to accommodate data sending. Such a proceeding could cause serious latency in network access. Described in the present patent disclosure are embodiments to reduce the access time by giving proactive grants through inspecting downlink (DL) data sent to the UE or uplink data being transmitted from the UE. The uplink data may be predictive since it maybe in lieu of requirement for sending a TCP acknowledgement for the DL TCP data scheduled earlier. For voice calls, a ML system for system may be deployed to predict when proactive UL grants may be given.

Abstract: In a typical data plane application, there is a packet dispatcher which receives packets from the underlying subsystem for distribution among various threads/processes for further processing. These threads/processes may run on various processing elements (PEs) and pass through multiple stages of processing. As new generation system-on-a-chip (SoC) architectures have multiple heterogeneous clusters with corresponding PEs, packet processing may traverse through multiple PEs in different clusters. Since latencies/performance for different clusters/PEs may be different, packet processing on the SoC may take a variable amount of time, which may lead to unpredictable latencies. The present disclosure provides embodiments to solve the problem of packet processing on heterogeneous clusters/PEs by providing a fast path enabler to the applications for SoC architecture awareness.

Abstract: System and method embodiments are disclosed for wireless channel information sharing to improve system performance in a wireless communication system. A software convergence layer is incorporated to query and keep track of all clients connected with the wireless communication system through different wireless technologies, such as 5G and/or WLAN. The shared channel information may be modeled into a set of coordinates. For each coordinate, a set of operational parameters, such as beamforming weights, Tx and Rx rate, Tx power, and Rx gain on a per-channel basis are determined. These operational parameters are passed onto schedulers of the different wireless technologies, which then use these operational parameters when clients are around corresponding coordinates.

Abstract: System and method embodiments are disclosed for high availability management for open radio access network (O-RAN). The O-RAN may be deployed on cloud with the O-CU deployed on a region cloud, O-RUs deployed on a cell site O-Cloud, and O-DUs deployed on an edge cloud. Each O-RU may comprise one or more RF clusters, computation clusters, and interface clusters. O-RU instances and O-DU instances may be instantiated with redundancy on the cell site O-Cloud and on the edge cloud, respectively, to serve one or more users. Local and central high-availability (HA) managers may be used to monitor O-RU instance performance for failure prediction/detection and to monitor internal states of each O-DU instance. In response to O-RU instance failure or O-DU internal states beyond/below state thresholds, new O-RU or O-DU instances may be instantiated as replacement instances for O-Cloud high availability management.

Abstract: Described in the present disclosure are system and method embodiments for 5G and WLAN private network convergence to improve Quality of service (QoS) and Quality of experience (QoE) by switching, steering or splitting the traffic using a cognitive layer. The Cognitive layer may sense signal conditions and learn user preferences for traffic allocation between available Wi-Fi and 5G networks. In embodiments, the cognitive layer may comprise an Artificial Intelligence (AI) or Machine Learning (ML) module, signal conditions sensor, and user QoS/QoE aware schedulers. A cloud-based service controller may be incorporated to make decisions on user QoS and QoE allocation based on the cognitive layer input. Implementation of the network convergence embodiments may improve QoS/QoE.

Abstract: Advances in wireless technologies have resulted in the ability of a 5G communication system to support multiple wireless communication applications. Each of these applications requires special handling in all layers and more so in scheduler and physical layer. The present disclosure presents embodiments of dynamical creating a computation instance with a slice of resources allocated for each scheduling input. Each computation instance may be independently managed, controlled, and customized according to the specific requirements of the corresponding scheduling input. Such a dynamic resource allocation allows large number of slices in PHY layer. Furthermore, when overloading happens, one scheduling inputs may be migrated from one distribution unit (DU) to another DU without interruption for end users during scheduling migration. Accordingly, efficiency and robustness of a 5G communication system may be improved to serve multiple wireless communication applications.

Abstract: System and method embodiments are disclosed to improve radio access network coverage area, increase throughput, and reduce power consumption in user equipment (UE). Downlink (DL) and uplink (UL) are disaggregated in one or more radio units (RUs). A UE receives DL data packets from a DL RU and uploads UL data packets to a UL RU disaggregated from the DL RU. The UL RU couples to a distributed unit (DU) directly or via the DL RU such that an acknowledgment or error message for successful or unsuccessful reception of the UL data packets may be sent back to the UE via the DL RU. The DU may track a UE motion trajectory and re-map UL traffic from one UL RU to another UL RU. Embodiments of DL/UL disaggregation may improve power efficiency and be advantageous for various applications such as internet of things, cyber physical systems, 5G communications, etc.

Abstract: With advanced compute capabilities and growing convergence of wireless standards, it is desirable to run multiple wireless standards, e.g., 4G, 5G NR, and Wi-Fi, on a single signal processing system, e.g., a system on a chip (SoC).
