Data transmission method and apparatus

A data transmission method, the method comprising:

• receiving, by a network device, at least two transmit sequences sent by a user equipment, wherein the at least two transmit sequences are sent using at least two signature sequences, the at least two signature sequences obtained by the user equipment based on a scheduling acknowledgment message sent by the network device;
• obtaining, by the network device, the at least two signature sequences used by the user equipment to send the at least two transmit sequences;
• and
• separately detecting, by the network device, a corresponding transmit sequence based on each signature sequence, to obtain at least two data packets.

A data transmission apparatus, the data transmission apparatus comprising:

• at least one processor;
• a non-transitory memory coupled to the at least one processor and storing execution instructions for execution by the at least one processor, the execution instructions instructing the at least one processor to:
• obtain at least two signature sequences based on a scheduling acknowledgment message sent by a network device, wherein the at least two signature sequences are used to perform multiple access for at least two to-be-sent data packets;
• process the at least two to-be-sent data packets by respectively using corresponding signature sequences, to obtain at least two transmit sequences;
• and
• send the at least two transmit sequences on a same time-frequency resource.
