The invention relates to a wireless communication technology, in particular to a method, send DCI and uplink transmission system and device, used to solve the problems existing in the current DCI technology does not support the LTEA system, it is difficult to make the network side user terminal uplink transmission scheduling problem. The embodiment of the invention includes methods of sending DCI: the network generated for scheduling uplink transmission DCI sent by the network side; the generated DCI; among them, the DCI includes the following information: resource indication information for indicating the allocation of resources; modulation indication information for indicating modulation encoding order transmission block data; indication information for indicating whether the transmission of a new data transmission block; mapping instruction information for the corresponding relationship between instruction transmission block and the codeword; pre encoding indication information for indicating uplink transmission rank size and the precoding codeword index. The method of adopting the embodiment of the invention can improve the efficiency of uplink transmission.
