A method for implementing parallel multiuser data transmission, comprising: a primary node acquiring a transmission opportunity, TXOP, or a service period, SP; and the primary node utilizing a control/management frame carrying uplink multiuser control information to instruct a secondary node to perform uplink multiuser data transmission in the transmission opportunity or the service period, the control/management frame at least comprises a frame header and a frame body; wherein the frame header comprises: a transmission address field, a receiving address field and a frame control field, the transmission address field is used for indicating address information of a device for transmitting a feedback frame, the receiving address field is used for indicating destination information of receiving the feedback frame, and the frame control field is used for indicating that the frame where the frame control field is located is a feedback frame carrying multiple pieces of user data acknowledgement/paging information; and the frame body comprises: an acknowledgement/paging control field, M null acknowledgement/paging information fields, and N acknowledgement/paging information fields, wherein each acknowledgement/paging information field or null acknowledgement/paging information field corresponds to one user of uplink multiuser data transmission, and an expression "M+N" represents a total number of users; wherein the null acknowledgement/paging information field is used for instructing uplink multiuser to transmit uplink data at the beginning of a transmission period, first scheduling a certain user or some users to perform the uplink multiuser data transmission during multi-frame transmission, or instructing a user to perform uplink retransmission, wherein the acknowledgement/paging control field comprises: a frame format control field, a user number field and a paging indication field, wherein the frame format control field is used for indicating that the control/management frame is used for the acknowledgement/paging of uplink multiuser data, the user number field is used for indicating how many acknowledgement/paging information fields and null acknowledgement/paging information fields subsequently, a value of the user number field is the numbers of users "M+N" in the uplink multiuser data transmission, and the paging indication field is used for indicating whether the corresponding user is still able to transmit uplink data in a subsequent uplink multiuser radio frame. the primary node utilizing a control/management frame carrying uplink multiuser control information to instruct a secondary node to perform uplink multiuser data transmission in the transmission opportunity or the service period, the control/management frame at least comprises a frame header and a frame body; wherein the frame header comprises: a transmission address field, a receiving address field and a frame control field, the transmission address field is used for indicating address information of a device for transmitting a feedback frame, the receiving address field is used for indicating destination information of receiving the feedback frame, and the frame control field is used for indicating that the frame where the frame control field is located is a feedback frame carrying multiple pieces of user data acknowledgement/paging information; and the frame body comprises: an acknowledgement/paging control field, M null acknowledgement/paging information fields, and N acknowledgement/paging information fields, wherein each acknowledgement/paging information field or null acknowledgement/paging information field corresponds to one user of uplink multiuser data transmission, and an expression "M+N" represents a total number of users; wherein the null acknowledgement/paging information field is used for instructing uplink multiuser to transmit uplink data at the beginning of a transmission period, first scheduling a certain user or some users to perform the uplink multiuser data transmission during multi-frame transmission, or instructing a user to perform uplink retransmission, wherein the acknowledgement/paging control field comprises: a frame format control field, a user number field and a paging indication field, wherein the frame format control field is used for indicating that the control/management frame is used for the acknowledgement/paging of uplink multiuser data, the user number field is used for indicating how many acknowledgement/paging information fields and null acknowledgement/paging information fields subsequently, a value of the user number field is the numbers of users "M+N" in the uplink multiuser data transmission, and the paging indication field is used for indicating whether the corresponding user is still able to transmit uplink data in a subsequent uplink multiuser radio frame.
