1. A secondary cell activation method, comprising:
receiving, by a terminal device, second indication information from a network device, wherein the second indication information indicates a report quantity of a second channel state information (CSI) report;
sending, by the terminal device, first indication information to the network device, wherein the sending the first indication information comprises sending the second CSI report to the network device based on the second indication information, and wherein the first indication information indicates receive beam direction information of the terminal device and the second CSI report comprises the receive beam direction information, wherein 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, wherein the first indication information comprises a valid indication, wherein the valid indication indicating that the receive beam direction information is valid causes the network device to configure the CSI-RS resource based on the receive beam direction information, wherein the valid indication indicating that the receive beam direction information is invalid indicates that the receive beam direction information is one of an intermediate beam sweeping result or an invalid measurement result, and wherein the valid indication indicating that the receive beam direction information is invalid causes the network device to ignore the receive beam direction information;
receiving, by the terminal device, configuration information from the network device, wherein the configuration information configures the CSI-RS resource;
sending, by the terminal device, an invalid CSI report to the network device, wherein the invalid CSI report being invalid indicates that secondary cell activation has started; and
sending, by the terminal device, a first CSI report to the network device, wherein the first CSI report is obtained based on the CSI-RS resource, and wherein the first CSI report is used to activate the secondary cell, and wherein the first CSI report is a valid CSI report indicating that the secondary cell activation is completed.
