    Abstract: This application discloses communication methods and communication apparatuses. A terminal device receives indication information from a network device. The indication information includes one or more indication parameters. The terminal device obtains one or more pieces of configuration information based on the indication parameters. The terminal device performs uplink or downlink data transmission according to the one or more pieces of configuration information. Each pieces of configuration information includes information of a starting location and information of a quantity of time domain symbols in a slot that are occupied by uplink data or downlink data. Each piece of configuration information is selected from a first set of configuration information or a second set of configuration information. The first set of configuration information corresponds to a first mapping type of a physical downlink shared channel (PDSCH) and the second set of configuration information corresponds to a second mapping type of the PDSCH.

    Abstract: Embodiments of the present invention provide a control channel position determining method, a device, and a processor-readable storage medium. A terminal device determines an available unlicensed band set and a control channel resource group, and determines at least one first unlicensed band to which at least one of control channel resource groups belongs, based on bitmap information or offset information. The at least one first unlicensed band belongs to the available unlicensed band set. Compared with that a control channel resource group is semi-statically configured to belong to a first unlicensed band, according to the embodiments of the present invention, no matter how an available unlicensed band included in an available unlicensed band set changes, a first unlicensed band to which at least one control channel resource group belongs can always be determined, thereby ensuring normal communication.

    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.
