A data scheduling method, performed by a base station, using an unlicensed spectrum resource, comprising: sending a configuration message to a user equipment, wherein the configuration message comprises configuration parameter information of at least one unlicensed-spectrum serving cell; and sending a scheduling command according to the configuration parameter information to the user equipment, so as to send data to or receive data from the user equipment over the at least one unlicensed-spectrum serving cell, wherein the scheduling command is used for sending or receiving the data; wherein the configuration parameter information comprises a feedback parameter corresponding to the data, wherein the feedback parameter includes a start position and an end position of a scheduled Orthogonal Frequency Division Multiplexing, OFDM, symbol of the at least one unlicensed-spectrum serving cell or of a scheduled, Physical Resource Block, PRB, of the at least one unlicensed-spectrum serving cell or positions of the first N OFDM symbols and/or positions of the former N PRBs, which are used to locate a position of feedback data in a foregoing feedback message, where N is a positive integer, wherein the method further comprises: receiving from or sending to the user equipment a data feedback message corresponding to the data, wherein in the data feedback message, feedback information is a one-to-one correspondence with the data, wherein the one-to-one correspondence is determined according to the feedback parameter in the configuration parameter information and wherein for the feedback information at each position, one piece of data is corresponding to the feedback information at this position, where the feedback information is used to feed back a data receiving status at this position. sending a configuration message to a user equipment, wherein the configuration message comprises configuration parameter information of at least one unlicensed-spectrum serving cell; and sending a scheduling command according to the configuration parameter information to the user equipment, so as to send data to or receive data from the user equipment over the at least one unlicensed-spectrum serving cell, wherein the scheduling command is used for sending or receiving the data; wherein the configuration parameter information comprises a feedback parameter corresponding to the data, wherein the feedback parameter includes a start position and an end position of a scheduled Orthogonal Frequency Division Multiplexing, OFDM, symbol of the at least one unlicensed-spectrum serving cell or of a scheduled, Physical Resource Block, PRB, of the at least one unlicensed-spectrum serving cell or positions of the first N OFDM symbols and/or positions of the former N PRBs, which are used to locate a position of feedback data in a foregoing feedback message, where N is a positive integer, wherein the method further comprises: receiving from or sending to the user equipment a data feedback message corresponding to the data, wherein in the data feedback message, feedback information is a one-to-one correspondence with the data, wherein the one-to-one correspondence is determined according to the feedback parameter in the configuration parameter information and wherein for the feedback information at each position, one piece of data is corresponding to the feedback information at this position, where the feedback information is used to feed back a data receiving status at this position.
