Abstract: Embodiments of the present invention provide a channel-state information process processing method, a network device, and a user equipment, where the channel-state information process processing method includes: after receiving a first channel-state information CSI request sent by a first network device, if CSI corresponding to multiple aperiodic CSI processes has not been reported by a user equipment, dropping CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes, where each CSI process is associated with a channel measurement resource and an interference measurement resource. A problem existing after a CoMP technology is introduced can be solved that the UE cannot implement processing of multiple CSI processes.

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.
