METHOD FOR SENDING AND RECEIVING CONTROL INFORMATION, APPARATUS AND COMMUNICATION SYSTEM

摘要

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.

主权项

1. A method for sending control information, comprising:
generating, by a network side, downlink control information (DCI) for a terminal, wherein the DCI does not include a transmission block to codeword swap flag control bit in case that a dedicated demodulation reference signal used to demodulate data is preconfigured by the network side for the terminal, and the DCI includes the transmission block to codeword swap flag control bit in case that the dedicated demodulation reference signal used to demodulate data is not preconfigured by the network side for the terminal; and sending, by the network side, the generated DCI to the terminal.
