  • Publication number: 20240089040
    Abstract: Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

  • Publication number: 20240086730
    Abstract: At least one processor identifies dependency relationships among libraries in a repository of libraries. Using the dependency relationships among libraries, at least one machine learning model can be created that predicts with a confidence value a dependency between a given library and a target library. An L layer tree-like graph can be created, using the dependency relationships among libraries and an application package. L can be configurable. Versions of the libraries to use can be determined by running the at least one machine learning model for each pair of nodes having a dependency relationship in the L layer tree-like graph, the at least one machine learning model identifying the dependency relationship with a confidence value, where pairs of nodes having largest confidence values are selected as the versions of the libraries to use in the application package.

  • Patent number: 11929446
    Abstract: Provided is a preparation method of a detector material. The present disclosure epitaxially grows a buffer layer on a surface of a gallium arsenide substrate, deposits a silicon dioxide layer on the buffer layer, and etches the silicon dioxide layer on the buffer layer according to a strip pattern by photolithography and etching to form strip growth regions with continuous changes in width. Finally, a molecular beam epitaxy (MBE) technology is used to epitaxially grow the detector material in the strip growth regions under set epitaxy growth conditions. Because of the same mobility of atoms arriving at the surface of the substrate, numbers of atoms migrating to the strip growth regions are different due to different widths of the strip growth regions, such that compositions of the material change with the widths of the strip growth regions or a layer thickness changes with the widths of the strip growth regions.
