Optionally, before step X03, the method may further include: X04: Receive downlink control information sent by a base station, where the downlink control information includes an indication of a rule for mapping the uplink information onto the first sequence, an indication of the timeslot-level sequence, and a time-frequency resource for sending the second sequence. This step may be performed by the wireless transceiver Y02 in the user equipment. After X04, the method may optionally include: X05: Receive downlink data sent by the base station.
For example, the user equipment receives the DCI (downlink control information) sent by the base station. The DCI includes scheduling information required by the user equipment for receiving the downlink data. Optionally, the DCI further includes an indication of a rule for mapping the ACK onto the first sequence when the user equipment generates the first sequence, an indication of the timeslot-level sequence when the user equipment performs a spectrum spreading operation, and time and frequency resources used for sending the second sequence. For example, the DCI may include an OVSF code. The user equipment generates, according to the OVSF code, the first sequence indicating the ACK and NACK. The DCI may further include an index number of the timeslot-level sequence, a generation parameter of the timeslot-level sequence, or the like, where the index number is used to indicate a timeslot-level sequence in a timeslot-level sequence set, and the generation parameter is used to generate the timeslot-level sequence. The DCI may further include a start time at which the second sequence is sent, a frequency of a subcarrier on which the second sequence is sent, a quantity of retransmission times of the second sequence, and the like.
