Abstract: A terminal device generates at least two pieces of HARQ-ACK information based on a plurality of received PDSCHs, and sends the at least two pieces of HARQ-ACK information to a network device. Each piece of HARQ-ACK information includes an ACK or a NACK fed back for one or more PDSCHs. When a piece of HARQ-ACK information includes ACKs or NACKs fed back for a plurality of PDSCHs, at least one of the following of the plurality of PDSCHs corresponding to the HARQ-ACK information is the same: port groups to which ports of DMRSs used to demodulate the PDSCHs belong, identifiers of enabled transport blocks carried in the plurality of PDSCHs, and PDCCH configurations of a plurality of PDCCHs used to schedule the plurality of PDSCHs.

Abstract: This application provides a data sending and receiving method. The method includes: receiving, by a terminal device, a first PDCCH and a second PDCCH, where the first PDCCH is used to schedule a first PDSCH, and the first PDSCH is used to transmit first data; determining, based on the first PDCCH and the second PDCCH, a first resource used to transmit the first data, where the first resource is a part or all of a resource of the first PDSCH; and receiving, by the terminal device, the first data from a network device on the first resource. The first resource is determined with reference to the first PDCCH and the second PDCCH, to avoid a problem that receiving performance of the first PDSCH and the second PDCCH may deteriorate when a resource of the second PDCCH overlaps the resource of the first PDSCH.
