Abstract: This application provides a communication method and apparatus. A terminal device receives a correspondence between reporting information and a to-be-activated TCI state, and a configured one-to-one correspondence between at least one TCI state and at least one first field, so that the terminal device can determine a to-be-activated TCI state and a first field corresponding to the TCI state. Therefore, on the basis of an existing mechanism of TCI state activation, based on reporting information of a terminal, the terminal device can autonomously activate a TCI state, and associate the TCI state with a corresponding field, so that signaling overheads and an indication delay are reduced, to improve performance of data transmission, and achieve good forward compatibility.
