  • Patent number: 11265957
    Abstract: A Central Unit (CU) receives Fifth Generation Core (5GC) N2 signaling and generates Fifth Generation New Radio (5GNR) RRC signaling. The CU receives 5GC N1 signaling. The CU converts a first portion of the 5GNR RRC signaling into LTE RRC signaling and converts a first portion of the 5GC N1 signaling into LTE Non-Access Signaling (NAS). The CU transfers LTE Physical Layer High (PHY-H) signaling to an LTE Physical Layer Low (PHY-L) in an LTE Distributed Unit (DU). The CU transfers 5GNR PHY-H signaling to an 5GNR PHY-L in a 5GNR DU. The LTE DU receives the LTE PHY-H signaling and transfers the LTE RRC signaling and the LTE NAS signaling to LTE User Equipment (UE). The 5GNR DU receives the 5GNR PHY-H signaling and transfers the second portion of the 5GNR RRC signaling and the second portion of the 5GC N1 signaling to a 5GNR UE.

  • Publication number: 20220029751
    Abstract: In a wireless data network, a Distributed Unit (DU) receives Uplink (UL) server data from server applications in wireless User Equipment (UEs). The DU processes the UL server data with an UL DU Hybrid Automatic Repeat Request (HARQ), generates UL HARQ Acknowledgements (ACKs) based on the UL server data, and transfers the UL server data to a Central Unit (CU). The CU receives the UL server data, processes the UL server data with an UL CU MAC, and transfers the UL server data. The CU receives (Downlink) DL server data for the server applications in the wireless UEs and transfers the DL server data to the DU. The DU receives the DL server data from the CU, processes the DL server data with a DL DU MAC comprising a DL DU HARQ, and transfers the DL server data and the UL HARQ ACKs to the wireless UEs.

  • Publication number: 20210382646
    Abstract: File access statistics associated with a content file are maintained by a file tier agent of a secondary storage system. The content file is accessible via a primary storage system. A target storage tier corresponding to the file access statistics associated with the content file is determined according to one or more policies. At least a portion of data of the content file is migrated to the determined storage tier while accessibility of the content file via the primary storage system is maintained.

  • Patent number: 11191060
    Abstract: In a wireless network, a Distributed Unit (DU) receives Uplink (UL) data from User Equipment (UE) and a Central Unit (CU) receives Downlink (DL) data for the UE. When DL-centric applications in the UE use the DL, the CU executes most network applications and the DU executes a few network applications. When the DL-centric applications use the UL, the DU executes the network applications and the CU transfers the UL data to the core. When UL-centric applications in the UE use the DL, the CU routes the DL data to the DU, and the DU executes the network applications. When the UL-centric applications use the UL, the DU executes a few network applications and the CU executes most network applications to route the data to the core. Advantageously, the DU and the CU are optimized to process UL/DL data for a user application based on whether the user application is UL-centric or DL-centric.

  • Publication number: 20210265006
    Abstract: Provided herein are methods and associated compositions, kits, systems, devices and instruments useful for genetic analysis where there is/are a sequence(s) similar to the gene of interest in a sample. In the methods, a combined copy number for related genes (e.g., a gene of interest and its pseudogene) can be determined via an assay. In addition, relative amounts of the related genes, i.e., a ratio of the related genes can be determined via the assay. Using the data of the combined copy number and the ratio of the related genes, the genotype of the gene of interest (as well as its pseudogene(s), if desired) can be determined with high accuracy.

  • Patent number: 11102693
    Abstract: Systems and methods are described for assigning a mobility parameter to a wireless device. One or more measurement reports may be collected at an access node from the wireless device. A pathloss change for the wireless device may be calculated based on the collected measurement reports. When the calculated pathloss change exceeds a threshold, the wireless device may be instructed to report surplus transmit power at the access node. The reported surplus transmit power may be correlated to preset location environments and a position of the wireless device classified based on the correlation. A mobility parameter may be assigned for the wireless device.

  • Patent number: 10757584
    Abstract: A base station configures a TDD carrier to have a first TDD configuration for serving of a first UE and to have a second TDD configuration for serving of a second UE concurrently with the serving of the first UE. Such configuring causes the second UE to engage in an uplink communication in at least one subframe in which the first UE engages in a downlink communication, which could lead to interference issues. Therefore, the base station causes the second UE to apply uplink beamforming, so as to help minimize interference resulting from the second UE engaging in the uplink communication in the at least one subframe in which the first UE engages in the downlink communication.
