Abstract: A signal transmission method and apparatus are provided. The method includes: obtaining, by a transmitter, a to-be-sent data block; inserting one or more pilot blocks among a plurality of pieces of data of the to-be-sent data block based on an agreed position; and sending, by the transmitter, the to-be-sent data block into which the one or more pilot blocks are inserted. Inserting the one or more pilot blocks among the plurality of pieces of data of the to-be-sent data block can improve a phase noise compensation effect for a receiver without increasing pilot overheads.

Abstract: Embodiments provide a beam switching method and a related device. Under the method a first subframe sent by a base station by using a first beam can be received by a terminal device. The first subframe includes first-order downlink control information and second-order downlink control information. The terminal device can search for the second-order downlink control information based on the first-order downlink control information. The first-order downlink control information includes location indication information of the second-order downlink control information in the first subframe. The terminal device can switch from the first beam to a second beam based on the found second-order downlink control information to receive a second subframe. The downlink control information includes a switching indication field of the second beam. In this way, flexibility of beam switching is improved, load balancing of a control channel is implemented, and a latency of beam switching is reduced.

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.
