Data sending method and apparatus

A method of receiving data, comprising:

• performing, by user equipment, detection on a downlink control channel to obtain downlink control information, wherein the downlink control information comprises scheduling indication information and location indication information, and the scheduling indication information is used to indicate a frequency-domain location of data in a first subframe;
• determining, by the user equipment, a time-domain location of the data in the first subframe according to the location indication information in the downlink control information or a preamble signal received in an unlicensed spectrum before the downlink control channel, wherein the location indication information is used to indicate the time-domain location of the data in the first subframe;
• and
• receiving, by the user equipment, the data according to the frequency-domain location and the time-domain location of the data.

User equipment, comprising:

• a processor, configured to perform detection on a downlink control channel to obtain downlink control information, wherein the downlink control information comprises scheduling indication information and location indication information, and the scheduling indication information is used to indicate a frequency-domain location of data in a first subframe, wherein
• the processor is further configured to determine a time-domain location of the data in the first subframe according to the location indication information in the downlink control information or a preamble signal received in an unlicensed spectrum before the downlink control channel, wherein the location indication information is used to indicate the time-domain location of the data in the first subframe;
• and
• a receiver, configured to receive the data in the unlicensed spectrum according to the frequency-domain location and the time-domain location of the data.
