Abstract: A bandwidth adjustment method includes: determining a bandwidth update value of a channel of a first network system and a bandwidth update value of a channel of a second network system and a bandwidth update value of a protective bandwidth according to a request of a user or a channel condition, so that updated bandwidths of the channels of the first network system and the second network system meet the request of the user or are adapted to requirements of channel conditions. By using the technical schemes, a network resource can be adjusted between multiple network systems when the multiple network systems share one network resource, thereby helping improve the application efficiency of a bandwidth resource and ensuring anti-interference capabilities of the network systems.

Abstract: Embodiments of the present invention relate to a data transmission method, an access point, a relay node, and a data node for packet aggregation. The data transmission method for packet aggregation includes: determining an aggregation relay node in a service area, for aggregating a Medium Access Control (MAC) frame that is sent by a data node to an access point (AP) and is forwarded by the aggregation relay node; and receiving an aggregated MAC frame sent by the aggregation relay node, where the aggregated MAC frame is a MAC frame that is sent by the data node and is aggregated by the aggregation relay node. According to the embodiments of the present invention, a relay node is selectively used to aggregate data, so that aggregated packet data quickly reaches a scale for transmission, and the packet data is sent to a destination node within a short time, thereby significantly enhancing quality of service of a delay-sensitive application service.

Abstract: The present invention discloses a channel reservation method and a communications device. The method includes: generating, by a first device, a first indication frame, where the first indication frame is used for indicating a moment at which a second device sends a channel reservation frame, and the channel reservation frame is used for reserving a channel to be used when the first device sends data to the second device; and sending, by the first device, the first indication frame to multiple second devices. In the channel reservation method, a sender device in a data transmission process indicates a moment at which a receiver device sends a channel reservation frame, so that multiple receiver devices in the data transmission process send channel reservation frames at the same time, which avoids contention between the receiver devices in current data transmission, thereby reducing a collision probability, and reducing system overheads.
