Abstract: The present invention provides a method for sending and receiving control information, an apparatus and a communication system. The method for sending control information includes: setting respective control bits in a downlink control information (DCI) format to generate control information applied by a network side to a terminal, wherein indication information indicating whether to swap a corresponding relationship between a transmission block and a codeword is not carried in a control bit in the DCI format, if a dedicated demodulation reference signal used to demodulate data is preconfigured by the network side for the terminal and respective codewords correspond to the same number of layers; and the indication information is carried in a control bit in the DCI format, if the dedicated demodulation reference signal used to demodulate data is not preconfigured by the network side for the terminal; and sending the generated control information to the terminal.

Abstract: The present invention relates to an interference control method and device. The interference control method includes: performing neighboring cell measurement, and selecting at least one neighboring cell whose signal transmission strength is larger than signal transmission strength of a serving cell from measured neighboring cells as an interfering cell; parsing a physical broadcast channel PBCH of the interfering cell to obtain the number of antenna ports of the interfering cell; obtaining a cell reference signaling CRS location of the interfering cell according to a physical cell identifier PCI and the number of antenna ports of the interfering cell; and performing interference control according to information of the CRS location.
