    Abstract: In a control channel resource transmission method, user equipment (UE) obtains 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. The UE determines an antenna port according to the obtained configuration parameter, and then receives, through the antenna port, a control channel or a control channel element sent by the base station. The base station determines the antenna port according to the same configuration parameter as that of the user equipment, and sends, by using the antenna port, the control channel or the control channel element to the user equipment.

    Abstract: To facilitate sending a reference signal in a wireless communication environment, a transmitter sends a reference signal in a first time-frequency resource to a user equipment (UE); the transmitter sends data information in a first portion of a second time-frequency resource different from the first time-frequency resource to the UE; and the transmitter excludes data information from being sent in a second portion of the second time-frequency resource. The second portion of the second time-frequency resource is designated for use by another transmitter for sending another reference signal to the UE.

    Abstract: Embodiments of the present invention disclose an interference suppression method and a related device and system. The method includes: sending, on a specified time-frequency resource, a first reference signal or a first reference signal group to an interfered-with end; receiving interfering source information sent by the interfered-with end, where the interfering source information includes an interference identifier used for indicating whether a potential interfering source causes interference to the interfered-with end; and if the interference identifier in the interfering source information indicates that the potential interfering source sending the reference signal on the specified time-frequency resource causes interference to the interfered-with end, determining that the potential interfering source is an interfering source, otherwise, determining that the potential interfering source is a non-interfering source. According to the present invention, mutual interference between uplink and downlink signals of terminals located in a same cell or different cells can be suppressed.
