Abstract: A coordinated transmission control method, apparatus, and system. 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. An anti-interference beamforming manner is determined based on a specific cell configuration parameter, and whether to perform coordinated transmission is determined with reference to the dual decision condition of the interference test, wherein the primary and secondary access points learn an interference status in advance to prevent unnecessary retransmission resulting from interference caused during actual coordinated transmission, and to improve communication efficiency.

Abstract: The disclosure discloses a mobile photoelectric detection and identification system for low, slow and small targets. The optical detection subsystem and the photoelectric parallel processing and identification subsystem are arranged on the servo subsystem, and the servo subsystem is carried on an installation platform of a vehicle. The optical detection subsystem is configured to collect multi-wavelength band optical information from the target and the background. The co-processing module of various wavelength bands is configured to perform single-frame detection and identification of the target from the image information of the corresponding wavelength band. The information processing main control module is configured to use JPEG image compression, track association and multi-frame combining methods to perform a multi-frame detection and identification on the target. The servo subsystem is configured to complete target tracking according to the multi-frame detection and identification results.

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: Embodiments of this application relate to the wireless transmission field, and disclose a data transmission method and apparatus. The 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.

Abstract: A method includes obtaining multicast-broadcast single-frequency network MBSFN information, where the MBSFN information indicates a same first data sending manner, a same first channel, and a same first time point that are used when a plurality of forwarding devices send multicast data, where the multicast data is received from a control device; and forwarding the multicast data to at least one station device in the first data sending manner on the first channel at the first time point.
