Abstract: This application discloses a data reporting method, a data receiving method, and a related apparatus. In this application, a terminal device reports, to a network device, one group of information used to indicate scheduling bandwidth thresholds and/or scheduling MCS thresholds. Compared with directly reporting thresholds, in this application, fewer bits can be occupied, thereby reducing overheads.

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: This application provides a communication method and device. The method includes: A terminal device receives a reference signal from a network device, wherein the reference signal is not in a channel state information-reference signal (CSI-RS) resource set, configured with repetition on; and performs radio link monitoring (RLM) measurement or beam failure detection (BFD) measurement on the reference signal. According to the communication method and device provided in this application, the terminal device expects that the resource configured by the network device for performing BFD or RLM is not any resource in the CSI-RS resource set configured with the repetition on.

Abstract: This application provides a beam failure recovery method and an apparatus. The method includes: A terminal device receives configuration information of a cell, where the configuration information of the cell includes M beam failure detection resource groups and M candidate beam resource groups, the M beam failure detection resource groups are in a one-to-one correspondence with the M candidate beam resource groups, and M is an integer. When M is an integer greater than 1, and a beam failure occurs in at least one of the M beam failure detection resource groups, the terminal device sends, by using a first media access control control element (MAC CE), beam failure recovery information corresponding to the cell. According to the beam failure recovery method provided in this application, beam failure recovery can be performed in time.
