A method of providing, for a quadri-antenna user equipment, UE (12, 13), downlink control information used for uplink transmission in a management device of a Long Term Evolution-Advanced, LTE-A network, the method comprising the steps of: determining (S201, S301, S302) an uplink transmission scheme for said quadri-antenna UE (12, 13); semi-statically configuring, by high level signaling, the uplink transmission mode to which said uplink transmission scheme belongs; generating (S203, S303) downlink control information corresponding to said determined uplink transmission scheme, said downlink control information comprising a precoding matrix indicating field, and further comprising a new-data indicating field for a first transmission block and a new-data indicating field for a second transmission block; wherein, a transmission block disabling function is adopted in said determined uplink transmission scheme, a first value of said precoding matrix indicating field is used to represent disablement of one of the said first and second transmission blocks; and a combination of said new-data indicating field for said first transmission block and said new-data indicating field for said second transmission block is used to indicate the transmission disablement of both said two transmission blocks; said downlink control information further comprises respective redundant version fields of modulation-coding modes of said two transmission blocks, wherein, the redundant version field of modulation-coding mode of said disabled transmission block is utilized to represent the pre-coding matrix information of channel coding codeword which is mapped by the transmission block without being disabled; and transmitting (S204, S304) said generated downlink control information to said quadri-antenna UE. determining (S201, S301, S302) an uplink transmission scheme for said quadri-antenna UE (12, 13); semi-statically configuring, by high level signaling, the uplink transmission mode to which said uplink transmission scheme belongs; generating (S203, S303) downlink control information corresponding to said determined uplink transmission scheme, said downlink control information comprising a precoding matrix indicating field, and further comprising a new-data indicating field for a first transmission block and a new-data indicating field for a second transmission block; wherein, a transmission block disabling function is adopted in said determined uplink transmission scheme, a first value of said precoding matrix indicating field is used to represent disablement of one of the said first and second transmission blocks; and a combination of said new-data indicating field for said first transmission block and said new-data indicating field for said second transmission block is used to indicate the transmission disablement of both said two transmission blocks; said downlink control information further comprises respective redundant version fields of modulation-coding modes of said two transmission blocks, wherein, the redundant version field of modulation-coding mode of said disabled transmission block is utilized to represent the pre-coding matrix information of channel coding codeword which is mapped by the transmission block without being disabled; and transmitting (S204, S304) said generated downlink control information to said quadri-antenna UE.
