1. A secondary cell activation method, comprising:
receiving, by a terminal device, activation signaling of a secondary cell sent by a network device, wherein the activation signaling comprises at least one piece of first quasi co-location indication information; and activating, by the terminal device, the secondary cell based on the activation signaling;
wherein when the at least one of first quasi co-location indication information comprises a transmission configuration indicator (TCI) state identifier (ID), after receiving the activation signaling of the secondary cell, the terminal device determines a receive beam based on the TCI state ID carried in the activation signaling, and detects and receives a synchronization signal/physical broadcast channel block (SSB) by using the receive beam determined by using a TCI state corresponding to the TCI state ID, to complete activation of the secondary cell.
