Scheduling a data channel corresponding to a control channel

A base station, comprising:

• a receiver;
• a processor, configured to determine a first time period in which an end moment of a first control channel is located in a first transmission time interval (TTI), wherein the first TTI comprises at least two time periods, and a start moment of a data channel corresponding to a control channel that ends in each of the at least two time periods is located in a different TTI;
• and
• a transmitter, configured to send, to a terminal in the first TTI, control information carried on the first control channel, wherein the control information is configured to schedule a first data channel corresponding to the first control channel;
• wherein the processor is further configured to determine, based on the first time period, a second TTI in which a start moment of the first data channel is located;
• wherein the transmitter is further configured to send data of the first data channel to the terminal in the second TTI determined by the processor;
• or
• wherein the receiver is configured to receive, in the second TTI determined by the processor, data that is of the first data channel and that is sent by the terminal.

A terminal, comprising:

• a receiver, configured to receive, in a first time period in which an end moment of a first control channel is located in a first transmission time interval (TTI), control information that is carried on the first control channel and that is sent by a base station, wherein the first TTI comprises at least two time periods, a start moment of a data channel corresponding to a control channel that ends in each of the at least two time periods is located in a different TTI, and the control information is configured to schedule a first data channel corresponding to the first control channel;
• a processor, configured to determine, based on the first time period, a second TTI in which a start moment of the first data channel corresponding to the first control channel is located;
• and
• a transmitter, configured to send data of the first data channel to the base station based on the control information in the second TTI determined by the processor;
• or
• wherein the receiver is further configured to receive, based on the control information in the second TTI determined by the processor, data that is of the first data channel and that is sent by the base station.
