    Abstract: Embodiments of the present invention provide a method for transmitting uplink control information and an apparatus, applicable to a multi-carrier system. A user terminal receives physical layer signaling from a network device, where the physical layer signaling includes first indication information. The user terminal determines, according to the first indication information, a bit quantity of periodic CSI that can be sent on a channel resource or a piece quantity of periodic CSI that can be sent on a channel resource. The user terminal determines, according to the bit quantity or the piece quantity of the periodic CSI that can be sent, to-be-sent periodic CSI from periodic CSI corresponding to multiple downlink carriers. The user terminal sends HARQ-ACK information and the to-be-sent periodic CSI on the channel resource.

    Abstract: 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.
