摘要： A traffic control method includes an access point configured to decrease a value of a receive window (RWND) field in a Transmission Control Protocol (TCP) packet sent to a target station to obtain a modified TCP packet. The access point sends a downlink frame including the modified TCP packet to the target station. The TCP packet belongs to a non-key service.

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.

摘要： A contention adjustment method for use in an apparatus and a system in a wireless local area network. The method includes acquiring an air interface occupancy time ratio of a terminal that is in a service operating state, and adjusting an uplink data sending threshold of the terminal according to the air interface occupancy time ratio of the terminal, where the air interface occupancy time ratio of the terminal is a ratio of an air interface occupancy time of the terminal to an air interface time, and the air interface occupancy time of the terminal is a ratio of a volume of data sent by the terminal to an air interface data sending rate of the terminal in the air interface time. The present disclosure may avoid that a terminal with a stronger demand excessively preempts a terminal with a weaker demand.

摘要： A congestion control method includes that a first access point receives a first indication from a second access point; and the first access point performs traffic control on a non-key service of the first access point based on the first indication. The first access point is a neighboring access point of the second access point, and an operating channel of the first access point and an operating channel of the second access point overlap.

摘要： A wireless device and a radio frequency channel calibration method, where the wireless device includes a first radio frequency circuit and a second radio frequency circuit that operate on a same frequency band, and a processor. The first radio frequency circuit is configured to send a calibration signal using a calibration antenna. The second radio frequency circuit is configured to receive the calibration signal using each of at least two to-be-calibrated antennas. The second radio frequency circuit corresponds to at least two radio frequency channels, the at least two radio frequency channels respectively correspond to the at least two to-be-calibrated antennas. The processor is configured to determine a device phase difference of each of the at least two radio frequency channels, and calibrate a corresponding radio frequency channel using the device phase difference of each of the at least two radio frequency channels.
