  • Patent number: 11863393
    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.

  • Patent number: 11785669
    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. In the present disclosure, two baseband processors are used with each processor dedicated for one type of signal processing, such as 5G or Wi-Fi. The two baseband processors are interlinked via a chip-to-chip interconnect link for ingress and egress data transfer between the two processors. These two processors share an Ethernet link for benefits including cost saving, reduction in overall chipset power, and reduced form factor of the enclosure. Application of the disclosed embodiments may realize concurrent 5G Fronthaul and Wi-Fi traffic processing on the same Ethernet link. Such an application may be applied to other related scenarios, including Ethernet link sharing for dual Wi-Fi baseband processors, and Ethernet link sharing for Wi-Fi and gNodeB deployments, etc.

  • Publication number: 20230026248
    Abstract: Advances in wireless technologies have resulted in the ability of a wireless communication system to support wireless communications of different standards, e.g., 5G, LTE, and Wi-Fi. Different Wireless standards have aspects which are very different from each other. Described in the present disclosure are embodiments of architecture with hardware and software split to allow implementation of different wireless standards along a configurable signal process path. The configurable signal process path comprises software configurable operators that may be configured in a desired level of granularity to load desirable software to process signals of various standards on the same hardware. Embodiments of the disclosed architecture with hybrid hardware and software implementation may improve system operation efficiency and lower system complexity to serve communications across multiple wireless standards.

  • Patent number: 9008734
    Abstract: A wireless communication device is disclosed that is capable of reduced power consumption. Uplink and downlink sub-frames in a WiMAX, 802.16m or LTE environment often include several vacant symbols during which power-hungry hardware and software components need not operate at full power. By analyzing a physical layer beacon and control information of a received signal, the specific locations of data bursts can be determined, as well as periods of needed operation of a receiver module to effectively decode those data bursts. The receiver module can otherwise be controlled to operate in a LOW power state during remaining periods of vacant time, thereby conserving power consumption and extending battery life.

  • Patent number: 8112697
    Abstract: A method and apparatus for buffering an encoded signal having a plurality of codewords for a turbo decoder is provided. The method comprises de-interleaving each sub-block of the codeword received at the turbo-decoder; and storing LLRs of the de-interleaved codeword LLRs into an input buffer. Thereafter, each of punctured locations, if any, in the de-interleaved codeword is indicated to a read logic for enabling the latter to fill in each of those locations with a pre-determined LLR value as and when a read request corresponding to one of those locations arrives. This method obviates the need for storing the pre-determined LLRs at the punctured locations into the input buffer and thereby cuts down the input latency of turbo decoder significantly for higher code rates.
