Abstract: A method for indicating downlink control signaling and a related device are provided. The method includes: generating, by an access network device, indication information, and sending the indication information to a first terminal device by using downlink control signaling, where the indication information is used by the first terminal device to obtain information about an antenna port that is used by a second terminal device and that is corresponding to a demodulation reference signal, and the second terminal device is a terminal device currently performing spatial multiplexing together with the first terminal device. This implements interference detection performed by the first terminal device on a plurality of users.

Abstract: Embodiments of the present invention relate to a radio link reestablishment method and a controller. The method includes: if after sending downlink signaling or downlink data for designated times, a controller receives no corresponding acknowledgment returned by a user equipment in a cell dedicated channel state, or the controller receives a radio link failure indication message sent by a base station corresponding to the user equipment, the controller instructs the user equipment to re-search for a cell to trigger a cell update procedure, thereby improving reliability of a communications service, and ensuring normal running of the communications service.
