Abstract: Embodiments of the present invention provide an uplink information transmission method, a terminal device, and an access network device. The method includes: obtaining, by a terminal device, indication information for sending uplink information on a first symbol set of a target carrier; and sending, by the terminal device, the uplink information in a second time in a time occupied by the first symbol set. The second time is a time in the time occupied by the first symbol set other than a first time, and is a time in which the terminal device is allowed to access a channel of the target carrier to send the uplink information.

Abstract: The present disclosure provides a method and an apparatus for transmitting control data. The method includes: determining, by a terminal device, at least one target cell from at least one unlicensed cell; and transmitting, by the terminal device, control data in the target cell. This can implement transmission of the control data on an unlicensed spectrum resource, so that the control data can be transmitted not merely on a licensed spectrum resource, and communication reliability and user experience can be improved. In addition, this can reduce licensed spectrum resource overheads in a communication process, and increase a capacity of a communications system that has a limited quantity of licensed spectrum resources.

Abstract: A data receiving/transmitting method, a device, a storage medium, and a program product are provided. The data receiving method is applied to a terminal device in a new radio NR system, and the data receiving method may include: receiving, by the terminal device on a first carrier in a first time unit, first control information sent by an access network device, where the first control information is used to indicate a first start symbol on which a first data channel is received; and receiving, by the terminal device in the first time unit or a time unit after the first time unit, the first data channel on the first carrier starting from the first start symbol. In this solution, the terminal device can listen to a control channel and receive a data channel without being restricted to using some fixed subframes, thereby improving data receiving flexibility.

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.
