摘要： 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.

摘要： With advanced compute capabilities and growing convergence of wireless standards, there is requirement to run multiple wireless standards, e.g., 4G, 5G, and Wi-Fi, on a single hardware together. Typical solution includes reserving some computing resources for specific wireless standards. Such a resource strategy may not be optimized or efficient according to the real needs for various wireless standards. The present disclosure presents embodiments of using a unified resource controller to take multiple scheduling inputs across various wireless standards, allocate resources among a plurality of configurable processing units, and manage hardware components for data path accelerations including forward error correction, and signal processing implementation. The multiplexing multiple wireless technologies based on spectral utilization may improve the efficiency in power consumption and hardware resources utilization.

摘要： Enhanced Common Packet Radio Interface (eCPRI) based Fronthaul forms the foundation for open radio access network (O-RAN). O-RAN envisages splitting the radio into two parts, a Distributed Unit (DU) and Radio Units (RU), interconnected using high speed Fronthaul links. O-RAN and eCPRI for 5G/NR place demands for high speed Fronthaul with low latency, and high network bandwidth requirements. In the present disclosure, embodiments for configurable eCPRI Fronthaul solutions are disclosed. Various hardware accelerator implementations are presented for control plane and user plane traffic. The hardware accelerator implementation may support DU and RRU functionality required by eCPRI with minimal software intervention. The configurable eCPRI Fronthaul may support different data flows and meet different performance demands of DU and RRU. Scalable architecture may be applied for the configurable eCPRI Fronthaul to allow stacking of multiple hardware accelerators via a high-speed network interconnect, and overall performance and throughput may be improved.

摘要： 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). Such an implementation may require simultaneously receiving and transmitting signals corresponding to each wireless standard and also signal processing according to respective requirements. Typical solutions involve providing separate hardware blocks specific to each wireless standard, which in turn requires more area on the SoC and consumes more power. Embodiments of the present disclosure provide a unified hardware that may process signals across different standards in both a transmitting direction and a receiving direction simultaneously.

摘要： With advanced compute capabilities and growing convergence of wireless standards and artificial intelligence (AI) applications, there is a requirement to run multiple wireless standards, e.g., 4G LTE, 5G NR and Wi-Fi, and AI on a single hardware together. Typical solutions include reserving some compute resources for specific wireless standards and a dedicated AI resource due to different precision compared to baseband processing. Typical solutions for signal processing with converged wireless standards and machine learning (ML) applications include having dedicated hardware acceleration and reserving some commutating or processing resources for specific wireless standards and a dedicated AI operation. Such approaches result in inefficient use of resources and lack of operation flexibility. The present patent document discloses embodiments to leverage commonalities in hardware acceleration for converged baseband and AI operators, thus achieving improved efficiency in power consumption and improved hardware resources utilization.

摘要： System and method embodiments are disclosed for scalable open radio access network (O-RAN) fronthaul traffic processing for distributed unit and radio unit. The system may be placed in an O-DU or an O-RU as a scalable O-RAN fronthaul traffic processing unit. O-RAN fronthaul traffic processing may be implemented in unified architecture with hardware-software (HW-SW) interaction in the form of Rx/Tx input descriptors and Rx/Tx output status descriptors. In the transmit direction, fronthaul packets are created with eCPRI header from a symbol memory where RB allocations are stored. In the receive path, from an ingress queues of Ethernet, resource block allocations are created and stored in the symbol memory. The discloses HW-SW interaction mechanism may be agnostic to cores of different architectures, support both RU and DU modes, and provides multiple transport encapsulation formats with scalability to meet various fronthaul traffic processing requirements.

摘要： Embodiments of unified wireless architecture are disclosed to support multiple types of outer transceiver operation across different wireless standards. In the unified wireless architecture, processing chains of different RAT specifications may be configured using a single digital signal processing or hardware accelerator chain. An interface/boundary between a signal processing engine (SPE) and an outer transceiver (OTRX) may be identified as complex number data samples for all RATs. The OTRX may take RAT-specific unique processing steps away from SPE. Pipelined hardware Accelerator blocks may be configured to perform operations across different RATs with controls over bandwidth, latency, and power.

摘要： 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. Biasing for the estimated interference power may be implemented separately or jointly with early termination parameter learning and/or HARQ retransmission request with parameter changes to improve signal detection and interference management.

摘要： 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.
