FIG10 a schematic diagram of the PUCCH resources respectively indicated by DCIO and DCI1. As shown in FIG10, the No. 1 PUCCH resource and the No. 2 PUCCH resource are different PUCCH resources. A quantity of encoded bits that the No. 1 PUCCH resource can carry is greater than that the No. 2 PUCCH resource can. Specifically, because a quantity of bits of UCI required to report only A/N1 may be greatly different from a quantity of bits of UCI required to report both A/N1 and the CSI, DCI1 allocates another PUCCH resource, namely, the No. 2 PUCCH resource. However, the No. 2 resource and the No. 1 resource occupy a same OFDM symbol. To be specific, the CSI, A/N0, and A/N1 that correspond to DCIO and DCI1 are reported at a same moment but by using different PUCCH resources.  FIG11 is a schematic structural diagram of an embodiment of a terminal device according to this application. As shown in FIG11, the terminal device of this embodiment may include a receiving module 11 and a sending module 12. The receiving module 11 is configured to receive a plurality of pieces of downlink control information DCI, where each of the plurality of pieces of DCI is used to trigger reporting of one piece of UCI and indicate a physical uplink control channel PUCCH resource carrying the UCI, the UCI includes at least one piece of channel state information CSI and response information, and PUCCH resources indicated by the plurality of pieces of downlink DCI occupy at least one same orthogonal frequency division multiplexing OFDM symbol. The sending module 12 is configured to send target UCI on a target PUCCH resource, where the target UCI includes UCI triggered by the plurality of pieces of DCI, and the target PUCCH resource is one of the PUCCH resources indicated by the plurality of pieces of DCI.

['2. The method according to claim 1, wherein the PUCCH resources indicated by the plurality of pieces of DCI are a same PUCCH resource, and the sending, by the terminal device, target UCI on a target PUCCH resource comprises: sending, by the terminal device, the target UCI and indication information on the target PUCCH resource, wherein the indication information is used to indicate a type of the target UCI, the type of the target UCI comprises a first type and a second type, UCI of the first type comprises channel state information CSI, and UCI of the second type does not comprise CSI, or, a quantity of bits of UCI of the first type is within a first preset range, and a quantity of bits of UCI of the second type is within a second preset range.', '22. A terminal device, comprising: a receiving module, configured to receive a plurality of pieces of downlink control information DCI, wherein each of the plurality of pieces of DCI is used to trigger reporting of  one piece of UCI and indicate a physical uplink control channel PUCCH resource carrying the UCI, the UCI comprises at least one piece of channel state information CSI and response information, and PUCCH resources indicated by the plurality of pieces of downlink DCI occupy at least one same orthogonal frequency division multiplexing OFDM symbol; and a sending module, configured to send target UCI on a target PUCCH resource, wherein the target UCI comprises UCI triggered by the plurality of pieces of DCI, and the target PUCCH resource is one of the PUCCH resources indicated by the plurality of pieces of DCI.']
