    Abstract: The present invention relates to the field of communications technologies, and in particular, to a data scheduling method and apparatus, so as to resolve a problem that performing data scheduling on a data node by different evolved NodeBs participating in CA may cause a case in which a range supported by a processing capability of the data node is exceeded, or may cause a case in which the data node cannot fully leverage a processing capability of the data node. The method includes: sending, by the data node, scheduling limitation indication information to a first communications node; receiving, by the data node, data scheduling information that is sent by the first communications node to the data node; and sending, by the data node, uplink data to the first communications node, or receiving, by the data node, downlink data sent by the first communications node according to the data scheduling information.

    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: Embodiments of the present invention provide an uplink control information sending method, an uplink control information receiving method, an apparatus, and a system. The method includes: receiving, by a terminal device, channel indication information from an access network device on a physical control channel; determining the channel resource set that is of N channel resource sets and that matches a type or a size of the UCI as a first channel resource set; determining a channel resource that is in the first channel resource set and that is indicated by the channel indication information; and sending uplink control information UCI to the access network device on the channel resource. A quantity of bits that need to be added to the channel indication information in the embodiments of the present invention is less than that in the prior art.

    Abstract: The present disclosure discloses a data transmission method, a device, and a system, relates to the communications field, and can resolve a prior-art problem that a receive end cannot correctly receive data because a starting moment of sending information on a license-exempt spectrum cannot be determined. A specific solution is as follows: A first device detects first information of a first serving cell in a preset time period of a first subframe on a first time resource or a first time set of a subframe on a first time resource, determines a starting position of a second time resource according to the first information, and detects second information of the first serving cell in a second time set of a subframe on the second time resource. The present disclosure is used for data transmission.
