Abstract

Embodiments of the present invention provide a control channel resource transmission method including: obtaining, by a user equipment, a configuration parameter in a candidate control channel set according to a preset protocol and/or higher-layer signaling sent by a base station, where the higher-layer signaling is used to notify the configuration parameter; determining an antenna port according to the obtained configuration parameter; receiving, by using the antenna port, a control channel or a control channel element sent by the base station; and determining, by the base station, the antenna port according to the same configuration parameter as that of the user equipment, and sending, by using the antenna port, the control channel or the control channel element to the user equipment. The embodiments of the present invention are applicable to control channel resource transmission.
