Abstract
(EN)

Embodiments of this application provide a control information sending method and apparatus. A network device generates first control information for a first TB, where the first TB includes n code block (CB) groups, where N is a maximum quantity of CB groups included in the first TB; each CB group includes at least one CB; the first control information includes N control information fields, and the N control information fields are in correspondence with the maximum N CB groups included in the first TB; and a control information field i in the N control information fields is used to indicate whether a CB group corresponding to the control information field i is to be sent or received, and i∈[1, N]. In this way, a quantity of bits included in downlink control information can remain fixed, thereby reducing blind detection complexity of a terminal device.
