Abstract: The present disclosure relates to a method for sending cell common control reference information. In one example method, before common control information needs to be sent, a base station having M antenna ports generates the cell control reference information used to detect the common control information. The base station maps the common control information and the cell control reference information to one or more resource units (RUs) of N antenna ports. The N antenna ports are a subset of the M antenna ports. The base station uses the one or more RUs to send the common control information and the cell control reference information used to detect the common control information to a user equipment (UE) within a coverage area of the base station.
