Abstract: This application provides a beam failure recovery method, an apparatus, and a system. In this solution, a terminal device receives first configuration information from a network device, and performs cell-level beam failure recovery or transmission reception point level (TRP-level) beam failure recovery based on the first configuration information. The first configuration information is used to configure a plurality of sets of beam failure detection resources and a plurality of sets of candidate beam resources. Based on this solution, the terminal device may perform partial beam failure recovery based on the plurality of sets of beam failure detection resources and the plurality of sets of candidate beam resources, so that the terminal device can detect a TRP-level beam failure and recover the TRP-level beam failure in time. This effectively improves smooth system evolution.

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: A reference signal transmission method and a communications device are described. The method includes determining, by a first communications device, a first frequency band based on a first initial resource index, a second initial resource index, a first configured bandwidth, and a second configured bandwidth. The first initial resource index is greater than or equal to the second initial resource index, and the first initial resource index is less than or equal to a sum of the second initial resource index and the second configured bandwidth. The method further includes receiving, by the first communications device, a reference signal on the first frequency band. When this application is implemented, an actual transmission bandwidth of the reference signal can be accurately determined.

Abstract: A PTRS processing method and an apparatus. The method includes: receiving, by a terminal, first indication information and second indication information from a network device, where the first indication information is used to indicate a time-domain location at which a PTRS is to be sent by the terminal, and the second indication information is used to indicate an offset of an initial time-domain location to which the PTRS is mapped by the terminal; mapping, by the terminal, the PTRS to one or more DFT-s-OFDM symbols based on the first indication information and the second indication information; and sending, by the terminal, the one or more DFT-s-OFDM symbols. In this way, the PTRS mapped to the DFT-s-OFDM symbol is offset at a DFT-s-OFDM symbol level, so that PTRS collision between terminals can be avoided to an extent, thereby improving phase tracking precision.

Abstract: This application provides a reference signal communication method and communication apparatus. The method includes determining a resource block offset of a frequency domain position of a phase tracking reference signal (PTRS) based on a frequency domain density of the PTRS, an identifier of a terminal device, and a first bandwidth, in accordance with a ratio of the first bandwidth to the frequency domain density of the PTRS being a non-integer. The first bandwidth is a bandwidth scheduled by a network device for the terminal device. The method further includes sending or receiving the PTRS based on the resource block offset of the frequency domain position of the PTRS.
