    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: Embodiments of the present invention provide an uplink control information transmission method, user equipment, and a base station. In a first uplink demodulation reference signal (UL DMRS) pattern, resource elements (Res) in one orthogonal frequency division multiplexing (OFDM) symbol in an uplink subframe are used to carry the UL DMRS. The method includes: mapping, by user equipment (UE), uplink control information (UCI) to REs in the uplink subframe according to the first UL DMRS pattern, where an OFDM symbol in which the REs carrying the UCI are located is adjacent to the OFDM symbol in which the REs carrying the UL DMRS are located; and sending, by the UE to a base station, the uplink subframe that carries the UCI.

    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.
