Abstract: Embodiments of the present disclosure provide a data communication method, a terminal device, and a network device. In the solution, a terminal device receives first indication information in a first time period; and the terminal device transmits first information in a second time period, where a duration of the first time period is a first time unit, a duration of the second time period is a second time unit, and a duration of the second time unit is greater than a duration of the first time unit. In this way, although the terminal device receives the first indication information in a first time unit N, the terminal device transmits the first information in a second time unit M whose duration is greater than that of the first time unit.

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.
