One example method includes obtaining at least two signature sequences used to perform multiple access for at least two to-be-sent data packets by a user equipment. The user equipment processes the at least two data packets by respectively using corresponding signature sequences, to obtain at least two transmit sequences. The user equipment sends the at least two transmit sequences to a network device on a same time-frequency resource. Then the network device obtains the at least two signature sequences used by the user equipment to send the at least two transmit sequences, and separately detects a corresponding transmit sequence based on each signature sequence, to obtain the at least two data packets. The user equipment can transmit a plurality of data packets on a same time-frequency resource in a same slot.
