Abstract: Example reference signal transmission methods and apparatus are described. In one example method, a base station divides a transmission bandwidth into a plurality of frequency domain units, and sends reference signal sending configuration information to a terminal. The terminal transmits a reference signal on one or more frequency domain units. The one or more frequency domain units and another frequency domain unit form a part of the transmission bandwidth supported by the base station. The terminal sends the reference signal on the one or more frequency domain units to the base station based on the reference signal sending configuration information.

Abstract: Embodiments of this application disclose a communication method, and a related device and system. The method includes: receiving, by a reception point, first indication information, where the first indication information is used to indicate a time-frequency resource location of a first demodulation reference signal of first data; receiving, by the reception point, second indication information, where the second indication information is used to indicate a time-frequency resource location of a second demodulation reference signal; and determining, by the reception point, a time-frequency resource location of the first data based on the time-frequency resource location of the second demodulation reference signal, and demodulating the first data based on the first demodulation reference signal. Receiving performance of the reception point can be improved. On the premise that a resource conflict does not occur, two base stations communicate with a terminal device by using a time-frequency resource allocated by a second base station.

Abstract: This application provides a wireless communication method and a communication apparatus. The method includes a terminal device receives a data frame from a second device by using a first device, and notifies the first device when the terminal device determines that a communication data block from the first device is not successfully received. After determining a protocol data packet corresponding to the communication data block, the first device notifies the second device that the first protocol data packet is not successfully transmitted. After determining a data unit that is in the data frame and that corresponds to the communication data block, the terminal device notifies the second device through second-step feedback.

Abstract: This application provides a data sending method and a communication apparatus. The method includes: A first node determines, based on a quality of a channel between the first node and a second node, a sending time for starting to send data, where the first node is one of several candidate previous-hop nodes of the second node. The first node starts to send the data to the second node at the sending time. According to the data sending method, when a node needs to send data to a next-hop node of the node, the node may determine, based on quality of a channel between the node and the next-hop node of the node, a sending time for starting to send the data.
