摘要： A handover method in a master-slave network, and a master device, and slave devices are provided. The method includes when a master device or a first slave device determines that a user device needs to be handed over to a second slave device, the first slave device sends, to the second slave device, a first identifier of a first network interface allocated by the first slave device to the user device, and first network connection information used after the user device establishes a connection to the first network interface of the first slave device. The first identifier of the first network interface and a second identifier of the user device correspond on a one-to-one basis. The first slave device deactivates the first network interface and the second slave device activates a second network interface.

摘要： Embodiments of the present disclosure provide a data transmission method and an apparatus. The method mainly includes: forming multiple antennas of a BS (base station) into a cross polarization antenna array, and calculating a weighted matrix of a to-be-transmitted data stream of the BS according to channel information between the BS and an MS (mobile station); performing weighted processing on the to-be-transmitted data stream of the BS according to the weighted matrix, and sending a data stream that has undergone the weighted processing from the BS to the MS. The embodiments of the present disclosure may enhance the demodulation performance because the cross polarization antenna array is adopted at the BS, and certain irrelevancy exists between cross antennas; therefore, the embodiments of the present disclosure may significantly enhance the overall performance of sending the data stream from a BS side to an MS side.

摘要： A channel management method and device for a wireless local area network (WLAN) in rail transport, where the method includes instructing, by the controller, a to-be-changed trackside access point (AP) to change an operating channel from an operating channel of a first vehicle-mounted AP on a first vehicle to an operating channel of a second vehicle-mounted AP on a second vehicle, where the to-be-changed trackside AP for the first vehicle is behind the first vehicle, and a distance of the to-be-changed trackside AP to the first vehicle exceeds a preset threshold. Because operating channels of two vehicle-mounted APs are different, interference between vehicle-mounted APs on one vehicle and a next vehicle is low. Moreover, a trackside AP behind a previous vehicle is instructed to change a channel such that a vehicle-mounted AP does not need to change a channel. Therefore, a handover time is short.
