摘要： Embodiments of this application provide a multi-screen unlocking method and an electronic device. The method is as follows: In response to receiving a first operation performed by a user on an electronic device, a first display displays a first screen lock interface, and a second display displays a second screen lock interface, where the first screen lock interface is different from the second screen lock interface. The second display displays a second unlocked interface in response to receiving a second operation performed by the user on the second display. A second application indicates the electronic device to switch from a screen-locked state to an unlocked state, and sends a first message to a first application. In response to the first message, the first application displays a first unlocked interface by using the first display. The first display is locked by using the first application, and the second display is locked by using the second application. The first application and the second application are two independent applications. In this way, the first display and the second display may display two different screen lock interfaces, thereby implementing differentiated display on each screen.

摘要： This application relates to the field of wireless communication technologies, and discloses an antenna subarray, an antenna array, and a polarization reconfiguration method and apparatus, to provide a polarization reconfigurable antenna and a manner for performing polarization reconfiguration on an antenna. The antenna subarray includes m antenna elements. m is an integer greater than or equal to 2. The m antenna elements are placed at an interval of 360/m degrees in sequence. A distance between any two adjacent antenna elements is less than 0.5 times an operating wavelength. The distance between any two antenna elements is controlled within 0.5λ, so that polarization reconfiguration may be implemented. In addition, compared with a conventional array antenna, a polarization reconfigurable antenna including such an antenna subarray has a small antenna diameter and a small spacing, and may avoid generation of a grating lobe during large-angle scanning.

摘要： This application relates to the field of wireless communication, and in particular, to an access method in a wireless communication system, to resolve a problem in the conventional technology that a network device cannot flexibly indicate one or more types of terminal devices to access a cell or be barred from accessing the cell. The method includes: A network device sends at least one piece of first information to a first terminal device, where the at least one piece of first information indicates at least one of a first access capability and first access permission. The first terminal device determines, based on the at least one piece of first information, whether the network device has a capability for access of the first terminal device and/or whether access of the first terminal device is allowed.

摘要： An information processing method, a terminal device, and a network device are provided. In one method, a first bit in downlink control information includes two bits, a bit status of the first bit may belong to a first state set or may be a second state, and a terminal device may perform multi-TB scheduling or single-TB scheduling based on the first bit. When the bit status of the first bit belongs to the first state set, the first state set is {01, 10, 11}, N=4, and the downlink control information includes a first field, the bit status of the first bit can be used to determine a quantity L of TBs scheduled by the downlink control information, and a bit status of five bits of the first field can be used to determine HARQ process numbers of the L TBs and information about the L TBs, so that the downlink control information supports scheduling for any quantity of TBs in N TBs, and may indicate any HARQ process number and any NDI information used for each scheduled TB. This improves scheduling flexibility.
