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.

Abstract: A data transmission method and a communications device resolve an existing problem that use of an unlicensed spectrum is interfered with between LTE devices when a padding is sent. The method includes: performing, by a communications device, CCA on an unlicensed spectrum; and when determining that the unlicensed spectrum is in an idle state, sending, by the communications device on a preset band resource in the unlicensed spectrum, a signal indicating that the communications device uses the unlicensed spectrum, where the preset band resource is a partial band resource in the unlicensed spectrum. Mutual interference between communications devices when the unlicensed spectrum is used is eliminated.

Abstract: The present invention provides a method for sending and receiving control information, an apparatus and a communication system. The method for sending control information includes: setting respective control bits in a downlink control information (DCI) format to generate control information applied by a network side to a terminal, wherein indication information indicating whether to swap a corresponding relationship between a transmission block and a codeword is not carried in a control bit in the DCI format, if a dedicated demodulation reference signal used to demodulate data is preconfigured by the network side for the terminal and respective codewords correspond to the same number of layers; and the indication information is carried in a control bit in the DCI format, if the dedicated demodulation reference signal used to demodulate data is not preconfigured by the network side for the terminal; and sending the generated control information to the terminal.
