Abstract: This application provides a method to improve resource utilization efficiency of an uplink control channel that carries feedback information. A terminal device receives one or more downlink channels carried in one or more first time units, the first time units belonging to in a time unit set; determines a second time unit for carrying feedback information corresponding to the downlink channels according to a first association relationship between the time unit set and the second time unit; determines a first codebook; and sends uplink control information including the first codebook in the second time unit. When one of the downlink channels is received in first time units that belong to a subset of the time unit set, and there is a second association relationship between the subset of the time unit set and the second time unit, the first codebook includes only feedback information corresponding to the downlink channel carried in the first time units in the subset.
