1. A method for communication, comprising:
receiving, at a terminal device, from a network device an indication for the terminal device to activate a target cell in a frequency range 2;
determining a condition as to whether the target cell and a transmit beam of the target cell for the terminal device are known to the terminal device, wherein the determining the condition includes:
determining whether the terminal device has reported the transmit beam to the network device during a predetermined period prior to receiving the indication;
determining, based on the condition, a delay for the terminal device to activate the target cell; and
activating the target cell based on the delay.
