A method for indicating a transmission parameter, comprising: when multi-user multi-input multi-output MIMO data are transmitted, using an indication signaling in a downlink control information format to indicate joint encoded parameters; characterized in that: the indication signaling includes 3 bits and has 8 values; wherein a first value indicates one layer, antenna port 7 and scrambling identity SCID=0 for the case that a single transport block is enabled, and indicates two layers, antenna ports 7 and 8 and SCID = 0 for the case that two transport blocks are enabled; a second value indicates one layer, antenna port 7 and SCID=1 for the case that a single transport block is enabled, and indicates two layers, antenna ports 7 and 8 and SCID = 1 for the case that two transport blocks are enabled; a third value indicates one layer, antenna port 8 and SCID = 0 for the case that a single transport block is enabled, and indicates three layers and antenna ports 7 to 9 for the case that two transport blocks are enabled; a fourth value indicates one layer, antenna port 8 and SCID =1 for the case that a single transport block is enabled, and indicates four layers and antenna ports 7 to 10 for the case that two transport blocks are enabled; a fifth value indicates two layers and antenna ports 7 and 8 for the case that a single transport block is enabled, and indicates five layers and antenna ports 7 to 11 for the case that two transport blocks are enabled; a sixth value indicates three layers and antenna ports 7 to 9 for the case that a single transport block is enabled, and indicates six layers and ports 7 to 12 for the case that two transport blocks are enabled; a seventh value indicates four layers and antenna ports 7 to 10 for the case that a single transport block is enabled, and indicates seven layers and antenna ports 7 to 13 for the case that two transport blocks are enabled; an eighth value indicates reserved for the case that a single transport block is enabled, and indicates eight layers and antenna ports 7 to 14 for the case that two transport blocks are enabled. the indication signaling includes 3 bits and has 8 values; wherein a first value indicates one layer, antenna port 7 and scrambling identity SCID=0 for the case that a single transport block is enabled, and indicates two layers, antenna ports 7 and 8 and SCID = 0 for the case that two transport blocks are enabled; a second value indicates one layer, antenna port 7 and SCID=1 for the case that a single transport block is enabled, and indicates two layers, antenna ports 7 and 8 and SCID = 1 for the case that two transport blocks are enabled; a third value indicates one layer, antenna port 8 and SCID = 0 for the case that a single transport block is enabled, and indicates three layers and antenna ports 7 to 9 for the case that two transport blocks are enabled; a fourth value indicates one layer, antenna port 8 and SCID =1 for the case that a single transport block is enabled, and indicates four layers and antenna ports 7 to 10 for the case that two transport blocks are enabled; a fifth value indicates two layers and antenna ports 7 and 8 for the case that a single transport block is enabled, and indicates five layers and antenna ports 7 to 11 for the case that two transport blocks are enabled; a sixth value indicates three layers and antenna ports 7 to 9 for the case that a single transport block is enabled, and indicates six layers and ports 7 to 12 for the case that two transport blocks are enabled; a seventh value indicates four layers and antenna ports 7 to 10 for the case that a single transport block is enabled, and indicates seven layers and antenna ports 7 to 13 for the case that two transport blocks are enabled; an eighth value indicates reserved for the case that a single transport block is enabled, and indicates eight layers and antenna ports 7 to 14 for the case that two transport blocks are enabled.
