    摘要： Spectrum access for Internet of things (IOT) applications including receiving information about expected use by a primary user of a spectrum band in a radio frequency spectrum. The spectrum band is classified into at least two working modes based on the expected use. The spectrum band is sensed to determine a current access pattern of the primary user. Based on the classifying and the sensing, one of the working modes is selected as a current working mode of the primary user. Transmissions are scheduled on the spectrum band using a current schedule that is responsive to the current working mode of the primary user. If the current working mode of the primary user changes, the sensing, selecting, scheduling, and determining whether the current working mode has changed are re-performed. Otherwise, the transmission scheduling and determining if the current working mode has changed are re-performed.

    摘要： Methods and apparatus for managing quality of service of computing resources are presented. For example, a method implemented on a processor for managing quality of service of computing resources includes identifying, by the processor, one or more devices of a user on a network of the user; obtaining, by the processor, at least one management module for the identified one or more devices; installing the at least one management module in the processor; monitoring, by the processor, the one or more devices of the user for a problem; and determining, by the processor, a domain in which a root cause of the problem resides and, optionally, the root cause of the problem. The management module comprises information pertaining to a corresponding device. Further, the method may detect quality of service (QoS) problems and determine if the problems reside in a user domain or a service provider domain.
