Abstract:
1. A method for determination of transmission rate in a wireless communication comprising a wireless router and a plurality of user devices, comprising the steps of: all user devices obtain channel information of their respective communication channels from the wireless router using a reciprocity method, when the wireless router broadcasts signals, and calculate the S/N rate (SNRori) of said channels; a user device transmits signals to the wireless router at a transmission rate determined by SNRori; said user device detects another user device that transmits signals to the wireless router, to obtain channel information of the other user device; said user device uses relation between its channel information and the channel information of the other user device to calculate an actual S/N rate (SNRproj) of its communication channel under the influence of the other user device; said user device uses the obtained SNRproj to adjust said transmission rate and starts to transmit signals; and after a predetermined period time, the wireless router stops to accept data transmission from all user devices.
