Abstract

A method for transmitting data at a high rate in a wireless LAN is provided. A wireless access pointrequests reliable node information from a wireless terminal having a transfer rate equal to or less than a predetermined transfer rate if data to be transmitted to the terminal occurs. The terminal produces a frame containing information related to reliable nodes that can communicate with the terminal and information of greatest transfer rates between the reliable nodes and the terminal, and transmits the frame to the access point. The access point selects an optimal relay node from the reliable nodes, based on the greatest transfer rates between the reliable nodes and the access point and transfer rates between the reliable nodes and the terminal, and determines if a relay gain exists when using the optimal node. If the relay gain exists, the access point performs relay transmission to the terminal; otherwise, it performs direct transmission to it.

Description

technical field [0001] The invention relates to a method for sending frames at a high rate, in particular to a method for sending frames at a high rate in a wireless local area network (LAN). Background technique [0002] LAN was developed as a wired network system in its initial stage. LAN has been developed rapidly mainly through small and medium-sized companies. With the rapid development of wireless communication technology, LAN is combined with wireless technology to develop into a wireless LAN widely used in various fields at present. [0003] Due to the fact that it is wireless, a wireless LAN allows a terminal to be used wherever it is in a specific area. will now refer to figure 1 The wireless LAN will be specifically described. [0004] figure 1 is a block diagram showing the configuration of a wireless LAN. In the wireless LAN, wireless terminals 110 , 120 , 130 , 140 and 150 are located around one access point (AP) 100 . The AP 100 may be connected to othe...
