摘要： In a data transmission method, a first communications device receives flag information sent by a second communications device. When the flag information indicates that one piece of control information can be used for scheduling of a plurality of transport blocks, the first communications device obtains transport block allocation information, where the transport block allocation information indicates the number of transport blocks scheduled by the control information and a bit state corresponding to each transport block. The first communications device sends data or receives data based on the information. Alternatively, when the flag information indicates that one piece of control information can be used for scheduling of only one transport block, the first communications device obtains HARQ process number information, where the HARQ process number information indicates an HARQ process number corresponding to the transport block scheduled by the control information. The first communications device sends data or receives data based on the information. The foregoing method and device may be applied to a communications system, for example, a V2X, an LTE-V, a V2V, an Internet of Vehicles, an MTC, an LTE-M, an M2M, or an Internet of Things (IoT).

摘要： This application provides a reference signal sending method, a reference signal receiving method, an apparatus, and a device, to provide a reference signal sending or receiving mechanism. A first network device determines at least one frequency reference point based on a first frequency band. The first network device generates a reference signal based on the at least one frequency reference point, and sends the reference signal in the first frequency band. A frequency reference point is determined based on a frequency band. In this case, both the first network device that sends the reference signal and a second network device that receives the reference signal may determine the frequency reference point based on the frequency band, and the two network devices may determine a same reference signal at a same frequency domain location, so that the reference signal sent by the first network device can be correctly detected by the second network device.

摘要： An information receiving method and an apparatus are disclosed. The method includes: receiving, by a terminal device, first power information and second power information from a network device; and determining a first maximum transmission power based on the first power information, and determining a second maximum transmission power based on the second power information, where the first maximum transmission power is a maximum transmission power to be used by the terminal device for transmitting a signal by a first radio access technology, and the second maximum transmission power is a maximum transmission power to be used by the terminal device for transmitting a signal by a second radio access technology. In addition, the terminal device can send uplink signals to the network device by using the first radio access technology and the second radio access technology in a TDM manner, thereby effectively avoiding a technical problem that the terminal device cannot normally transmit a signal because a sum of a transmission power when the first radio access technology is used and a transmission power when the second radio access technology is used may exceed maximum transmission power of the terminal device.
