Abstract
A communication method includes: a terminal device determining a first time unit for receiving downlink data, determining, based on a nonnegative integer k1 corresponding to the downlink data, a second time unit in which feedback information corresponding to the downlink data is located, where a length of the first time unit is greater than or equal to a length of the second time unit, k1 represents a quantity of time units from the first time unit to the second time unit, and the length of the second time unit is less than one slot, and sending, in the second time unit, a feedback codebook to the network device, where the feedback codebook includes the feedback information corresponding to the downlink data. A transmission latency of downlink data is reduced.
