Claim 0:
1. A secondary cell activation method, comprising:
sending, by an access network device to a terminal device, an activation command for activating a secondary cell;
sending, by the access network device to 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;
sending, by the access network device to the terminal device, the first reference signal, and
wherein the first configuration information comprises a reference signal sending time, wherein the reference signal sending time of the first reference signal is a relative 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.
