Abstract
This application discloses a communication method and apparatus that activate a secondary cell. If the activated cell is an unknown secondary cell, in response to a terminal device detecting the secondary cell, the terminal device may send indication information to a network device. The indication information is used to trigger the network device to send an RS. In this way, in response to receiving the indication information, the network device may send the RS to the terminal device. Therefore, the terminal device avoids waiting a long period of time for the network device to send a reference signal, which can reduce a delay for activating the secondary cell.
