摘要： Embodiments of this application provide a data scheduling method, an apparatus, and a system, to improve resource allocation flexibility when one piece of DCI schedules a plurality of TBs. A network device sends, to a terminal device, DCI used to schedule N TBs. After determining that a downlink channel that carries first M TBs in the N TBs is transmitted in consecutive first downlink time units, the network device sends the downlink channel carrying the M TBs to the terminal device in the first downlink time units. The terminal device receives the downlink channel carrying the M TBs. After determining that ACKs/NACKs corresponding to the M TBs are transmitted in consecutive first uplink time units, the terminal device sends the ACKs/NACKs corresponding to the M TBs to the network device in the first uplink time units. A start time of the first downlink time units is determined based on an end time of transmission of the DCI and a first delay, and a start time of the first uplink time units is determined based on an end time of the first downlink time units and a second delay.

摘要： This application provides a reference signal sequence transmission method. The method includes: generating a reference signal sequence based on a frame number of a radio frame; mapping at least a part of reference signals in the reference signal sequence to a resource position that corresponds to the radio frame and that is used to transmit the at least a part of reference signals; and sending the at least a part of reference signals or an orthogonal reference signal at the resource position, where the orthogonal reference signal is obtained by multiplying the at least a part of reference signals by a preset orthogonal code. When the reference signal sequence is generated, the reference signal sequence is generated based on the frame number of the radio frame, so that reference signal sequences in any two radio frames in each cell are different. Therefore, when a receiving device performs in-phase combination on received reference signal sequences in a plurality of radio frames, interference caused by a reference signal of an interfering cell to a reference signal of a local cell is reduced.
