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 the present disclosure provide methods for sending and receiving feedback information, user equipment, and an access network device, relate to the field of communications technologies. In one embodiment, UE receives, in a downlink subframe in a preconfigured downlink subframe subset, downlink data that is sent by an access network device by using a downlink shared channel and a DAI index indicator and a DAI total quantity indicator that are sent by using a downlink control channel. The UE determines an uplink subframe for sending feedback information corresponding to the downlink shared channel. The UE determines a codebook of the feedback information according to the downlink assignment index DAI index indicator and the DAI total quantity indicator. The UE performs channel coding on the feedback information according to the codebook. The UE sends the channel coded feedback information.
