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: 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 provide an information transmission method and device. The method includes: reporting, by a UE, a CQI value to an eNB; receiving, by the UE, an MCS value sent by the eNB, where the MCS value is determined by the eNB according to the CQI value; and receiving, by the UE, PDSCH data according to the MCS value, where the CQI value and the MCS value are determined according to a second set of tables, where a modulation scheme that can be supported by the second set of tables is higher than 64QAM. The embodiments of the present invention can improve system performance and reduce waste of feedback resources.
