摘要：
A Multi-Input Multi-Output (MIMO) transmission based method for transmitting and receiving Downlink Control Information (DCI) is provided. The method includes if it is determined that two TBs are currently needed to be dispatched, indicating information of layer numbers and precoding matrixes of uplink MIMO transmission with a precoding information domain in DCI for dispatching the uplink MIMO transmission, and transmitting the DCI, and if it is determined that one Transport Block (TB) is currently needed to be dispatched, indicating the information of the layer numbers and precoding matrixes of the uplink MIMO transmission with redundant information in the DCI and precoding information domain, and transmitting the DCI. The present invention may save bit number of the precoding information domain and reduce the signaling overheads of the DCI.
