Abstract

A secondary cell activation method and an apparatus, the method including sending, by a terminal device, first indication information to a network device, where the first indication information indicates receive beam direction information of the terminal device, and where the receive beam direction information is associated with a channel state information reference signal (CSI-RS) resource for activating a secondary cell of the terminal device, receiving, by the terminal device, configuration information from the network device, where the configuration information configures the CSI-RS resource, and sending, by the terminal device, a first channel state information (CSI) report to the network device, where the first CSI report is obtained based on the CSI-RS resource, and where the first CSI report is used to activate the secondary cell.
