Abstract: Disclosed are a method and apparatus for sending information, a method and apparatus for receiving information, a base station and a terminal. The method for sending information includes: configuring semi-persistent scheduling information for indicating N transmission opportunities in a semi-persistent scheduling period, where the N transmission opportunities include M transmission opportunities for transmitting data by a sending end, where N is an integer greater than 1, M is an integer, and 0<M?N; and sending the configured semi-persistent scheduling information to a terminal. Through the present disclosure, the problem, in the related art, that the semi-persistent scheduling cannot meet the requirement of low latency is solved, and scheduling flexibility is improved.

Abstract: 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.

Abstract: 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.

Abstract: A steady state control method for a three-phase double-mode inverter. Off-grid steady state control is composed of outer loop power droop control, voltage feed-forward quasi-resonant control, and inner current loop dead-beat control. Therefore, the response speed of the inverter is raised, and the influence caused by the load fluctuation of a micro-grid is inhibited. Based on the off-grid steady state control, grid-connected steady state control introduces phase lead control to the power droop control. Therefore, the output voltage of the inverter is always slightly ahead of the power grid voltage, which avoids the energy pour backward phenomenon of the inverter due to a phase error, and realizes stable and reliable running in the grid-connected mode.

Abstract: Traps from network devices are filtered and prioritized. Filtering and prioritization can be performed on specific types of traps, traps from specific devices and traps from specific enterprises. Filtering is performed to reduce the number of traps that are processed, and prioritization is performed to indicate the relative importance of the traps. The filtering and prioritization can be performed by a trap daemon, which is executed by a network manager. Priorities and filters can be assigned to the traps, devices and enterprises by a network administrator. This provides the network administrator with great flexibility in managing the traps according to the situation at hand.
