Claim 3:
4. A secondary cell activation method, comprising:
receiving, by a terminal device from an access network device, an activation command that indicates activating a secondary cell; and
receiving, by the terminal device, first configuration information of a first reference signal, wherein the first reference signal is a temporary reference signal for activating the secondary cell;
receiving, by the terminal device, the first reference signal according to the first configuration information, wherein the first configuration information comprises a reference signal sending time, wherein the reference signal sending time of the first reference signal is a time difference between a time at which the access network device sends the first reference signal and a time at which the access network device sends the activation command, or is a time at which the access network device sends the first reference signal, and wherein the first configuration information further comprises at least one of the following information:
a reference signal sending indication,
a reference signal period,
a reference signal time domain resource location,
a reference signal frequency domain resource location, and
a reference signal configuration index, wherein the reference signal configuration index indicates a location of reference signal configuration information.
