Abstract: Embodiments of the present invention provide a node grouping method, a node, and an access point (AP). The method comprises: receiving a grouping request sent by an AP; according to the grouping request, obtaining a received signal strength indicator (RSSI); obtaining a group Identity (ID) of a group determined according to the RSSI. In the embodiment of the present invention, nodes are grouped according to the RSSI, so as to solve the problems of contention collision and low network performance in a large-scale network, avoid the problem of unfair throughput incurred by the near-far effect, and reduce the phenomena of hidden terminals.

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.
