Abstract: A fingerprint unlocking method and a terminal are provided. The method may be applied to a terminal having an in-screen fingerprint detection function. When the terminal is in a screen-locked state, the terminal determines whether an operation of a user meets a preset condition. If the operation of the user meets the preset condition, a fingerprint recognition identifier is displayed on a touch display screen of the terminal. A display area of the fingerprint recognition identifier is an area in which fingerprint recognition can be performed. The method resolves a problem that the user cannot perform fingerprint unlocking because the user cannot see a position of a fingerprint detector.

Abstract: This application provides a phase tracking reference signal (PTRS) sending method and apparatus. The method includes: implicitly determining, by a terminal device based on obtained uplink grant information and a preset rule, a to-be-sent PTRS and an antenna port for carrying the to-be-sent PTRS, where the antenna port is selected from an antenna port set, and the to-be-sent PTRS is one or more of all available PTRSs; and putting the to-be-sent PTRS on the antenna port, and sending the to-be-sent PTRS on the antenna port. This implicit indication method can effectively reduce air interface signaling overheads and improve air interface efficiency.

Abstract: Embodiments of this application disclose a beam usage method, including: A first communication device determines a first beam and a second beam, where the first beam and the second beam are beams of a same type. The first communication device determines, according to a first rule, a beam used for a first control resource set, where the beam used for the first control resource set is the first beam and/or the second beam. In this way, the first communication device correctly applies a beam, that is indicated by a network device, to a channel corresponding to a control resource set, so that the channel corresponding to the control resource set is transmitted through the correct beam, to improve communication transmission performance.
