  • Patent number: 11405865
    Abstract: Embodiments of this application provide a multistation coordination-based data transmission method and apparatus. The method includes: receiving, by a station, second data of another station, different from the station, in a coordination group to which the station belongs; sending, by the station, first data to the other station, so that the other station generates a second aggregated frame that includes the first data and the second data; and sending, by the station, a first aggregated frame to an access point. The first aggregated frame includes the first data and the second data. This reduces a transmit power of a single station, and prolongs a service lifespan of the station.

  • Patent number: 11374870
    Abstract: This disclosure relates to the field of data communication, and provides a network congestion notification method, an agent node, and a computer device. When receiving a first data packet, an agent node adds a source queue pair number to a first data packet to obtain a second data packet, and sends the second data packet to a receive end by using a network node. In a process of forwarding the second data packet, if the network node detects network congestion, the network node generates a first congestion notification packet carrying the source queue pair number, and sends the first congestion notification packet to the agent node. Further, the agent node sends the first congestion notification packet to a transmit end, so that the transmit end decreases a sending rate of a data flow to which the first data packet belongs.
