  • Publication number: 20210357200
    Abstract: The management of applications in a computing environment often involves a significant number of computing operations, such as acquiring the application, deploying data objects in various locations, and configuring the application with respect to the deployed device. Conventional computing environments may provide inadequate support throughout a typical application life cycle, especially for a computing environment distributed across many devices. Instead, the computing environment may be represented in a deployable object hierarchy that may be distributed to various devices. An application management service may therefore be provided to install representations of the application in the object hierarchy, and to support many other aspects of the application life cycle, such as application discovery, sharing, updating, and removal.

  • Publication number: 20210352734
    Abstract: Enabling the co-existence of contention based random access (CBRA) and contention free random access (CFRA) is an effective technique to improve network flexibility and usage of network resources. In some embodiments, all available communication opportunities in the CBRA schedule and all available communication opportunities in the CFRA schedule may be used to generate a final schedule Different subsets of preamble indices are employed to ensure that both CBRA and CFRA communications can co-exist. In other embodiments, all available communication opportunities in the CBRA schedule, but only the dedicated communication opportunities in the CFRA schedule, may be used to generate a final schedule. As a result, a smaller subset of preamble indices is used.
