14. A terminal comprising:
a processor;
a transceiver; and
a memory configured to store one or more programs, wherein the processor is configured to invoke and execute the computer programs stored in the memory to cause the transceiver to:
receive downlink control information (DCI) scheduling preset information from a network device;
receive the preset information from the network device according to the DCI, the preset information at least comprising point-to-multipoint (PTM) transmission information; and
feed back hybrid automatic repeat request (HARQ) response information of the preset information to the network device, the HARQ response information comprising HARQ response information of the PTM transmission information, wherein the preset information comprises a plurality of pieces of PTM transmission information, and the transceiver configured to feed back the HARQ response information of the preset information to the network device is configured to:
feed back HARQ response information of the plurality of pieces of PTM transmission information to the network device by using a same uplink (UL) resource;
wherein if the network device indicates that the plurality of pieces of PTM transmission information are received by the terminal in a plurality of time slots, receiving, by the network device, the HARQ response information of the plurality of pieces of PTM transmission information fed back by the terminal by using the same UL resource comprises:
if a same UL resource is used for the HARQ response information of the plurality of pieces of PTM transmission information, and scrambling codes used for DCIs scheduling the plurality of pieces of PTM transmission information are partially the same,
receiving, by the network device, the HARQ response information of all PTM transmission information fed back by the terminal by using the UL resource.
