Abstract: A cell beam indication method and a related terminal device for receiving configuration information sent by a network device, where the configuration information is used to configure at least one cell group, and each cell group includes a first cell and a second cell. The terminal device determines, based on a first beam indicated via a first cell in a first cell group, a second beam corresponding to the first cell group, where the first cell group includes at least one multi-beam cell. The terminal device determines, based on the second beam, a third beam of a second cell in the first cell group. This method may be used for a multi-beam cell, to indicate that a common beam can be used for the multi-beam cell in a form of a cell group.

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.

Abstract: Example reference signal measurement methods, example resource indication methods, and example apparatuses are provided. One example method includes receiving at least one reference signal from a network device. Channel state information can then be determined based on some or all of the at least one reference signal. The channel state information can then be reported to the network device based on first duration. When it is determined to activate a first antenna panel and measure the at least one reference signal by using the first antenna panel, the first duration can be determined based on a first constraint relationship. The first antenna panel can be currently not activated.
