Abstract: A coordinated transmission control method, apparatus, and system are disclosed. A primary access point and a secondary access point determine whether to perform coordinated transmission through inter-cell configuration parameter sharing and based on a dual decision condition of an interference test, further determine an anti-interference beamforming manner based on a specific cell configuration parameter, and determine whether to perform coordinated transmission with reference to the dual decision condition of the interference test, so that the access points can learn an interference status in advance, thereby preventing unnecessary retransmission resulting from interference caused during actual coordinated transmission, and improving communication efficiency.

Abstract: The disclosure relates to the wireless transmission field, and discloses a data transmission method and apparatus. An example method includes: A transmit end generates a data packet; and the transmit end sends the data packet to a receive end, where the data packet includes at least two pieces of video service data having different priorities, and the pieces of video service data having different priorities are carried on different communications resources for transmission.
