Abstract: An RRC connection release control method and an apparatus are applied to the field of mobile communication technologies and relate to the field of artificial intelligence (AI) and machine learning algorithms. When a first application of a terminal runs in a foreground, a timing duration of a first timer is set based on a timing duration corresponding to the first application, where the first timer starts when the terminal is in an RRC connected state, and when the terminal exchanges information with a network device, the first timer is reset, so as to control release of an RRC connection of the terminal based on the first timer.

Abstract: In a storage medium management method, a controller receives an address space request that requests the provision of an address space in a target storage medium for an operating system, the target storage medium having two different types of storage media. The Controller determines a first address space in the target storage medium based on the address space request, and a physical address of the first address space to a target virtual address, which is managed by the operating system. The controller then provides to an operating system a first address space requested by the address space request, such that the first address space is directly managed by an operating system, without manual configuration or restart of an electronic device.

Abstract: Embodiments of this disclosure provide a channel state feedback method and apparatus. The method includes: A terminal device receives first indication information from a network device. The terminal device reduces a first value of first information to a second value based on the first indication information. The second value is used to determine channel state feedback information. The first information includes channel state indicator CQI information or signal-to-interference-plus-noise ratio SINR information. The channel state feedback information determined based on the second value is more accurate than channel state feedback information determined based on the first value. This can improve accuracy of the channel state feedback information.
