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.

Abstract: This application relates to the field of wireless communications and self-driving/intelligent driving, and in particular, to the field of collaborative radars. In a solution of this application, a first apparatus receives first information from a second apparatus; the first apparatus determines, based on the first information, priorities of a plurality of time-frequency resources included in a first time-domain range; and the first apparatus determines a first time-frequency resource in the plurality of time-frequency resources, where a priority of the first time-frequency resource is not lower than a priority of a time-frequency resource other than the first time-frequency resource in the plurality of time-frequency resources. A time-frequency resource with a comparatively high priority is selected to send a radar signal, to reduce a probability of a resource collision, and reduce or avoid interference between radars, especially collaborative radars.

Abstract: In the method, a terminal device receives first downlink control information from a network device, where the first downlink control information includes a first hybrid automatic repeat request (HARQ) process number. The terminal device receives, on a first frequency band, a first data packet carrying a first transport block, and receives, on a second frequency band, a second data packet carrying a second transport block, where the first HARQ process number corresponds to the first transport block on the first frequency band and the second transport block on the second frequency band. The terminal device performs joint decoding on the first data packet and the second data packet. The first transport block is the same as the second transport block. By using the method and the apparatus provided in the embodiments of the present invention, data transmission reliability in a multi-band transmission scenario can be improved.

Abstract: Embodiments of the present disclosure provide a data transmission method, a network device, and a terminal device. A network device configures N groups of scheduling information based on a requirement of a terminal device group, configures at least one piece of downlink data based on M groups of scheduling information in the N groups of scheduling information, and sends first downlink data to a first terminal device in a first transmission time unit. Correspondingly, the first terminal device determines the N groups of scheduling information, and detects the first downlink data in the first transmission time unit based on the N groups of scheduling information. In the process, the first downlink data can be successfully transmitted through a plurality of transmissions and one successful detection, thereby implementing highly reliable data transmission. In addition, not only low reliability of PDCCH dynamic scheduling is avoided without introducing a large quantity of control overheads, but also link adaptation can be obtained.
