Abstract: This application discloses a downlink data sending method, a downlink data receiving method, and an apparatus, and relates to the communication field, to resolve a problem that feedback information fails to be sent, and consequently, a retransmission probability of downlink data is increased, and data transmission efficiency is reduced. When at least two of P PDSCHs in one slot overlap in time domain, a network device cancels sending of partially overlapping PDSCHs. If one first PDSCH whose sending is canceled is the last repetition in PDSCH repetitions of first data, and a terminal device receives another repetition in the PDSCH repetitions of the first data before the first PDSCH, the terminal device still sends feedback information for the first data to the network device in a feedback slot corresponding to the first PDSCH.
