A communication method and apparatus are provided, to ensure in-order data scheduling in a scenario in which a PUCCH is transmitted in a plurality of cells. A network device sends first scheduling information and second scheduling information to a terminal device, where the first scheduling information is used to schedule a first PDSCH and a first PUCCH, the second scheduling information is used to schedule a second PDSCH and a second PUCCH, a time domain resource of the second PDSCH is located after that of the first PDSCH, a PUCCH is used to carry HARQ feedback information of a PDSCH, and the first PUCCH and the second PUCCH are located in different cells. The following scheduling result is not expected: The second PUCCH is located before the first PUCCH; or the first PUCCH and the second PUCCH are located in different reference time units, and the second PUCCH is located before the first PUCCH; or the first PUCCH and the second PUCCH are located in one reference time unit.
