Method adjacent auxiliary channel transmission, radio communication systems and apparatus

The present invention discloses an adjacent auxiliary channel transmission method, and a wireless communication system apparatus, including the adjacent channels to select the desired access point for wireless communication from a wireless transmission channel means and allows the now adjacent channels there is adjacent channel signals are transmitted auxiliary, auxiliary transmission signal is generated to determine the manner of the existing signal adjacent to the selected channel; generating an auxiliary transmission signal in a wireless communication apparatus according to a local auxiliary transmission signal generation mode determined, and transmitting the auxiliary signal corresponding to the adjacent channel. The method of the present invention, an auxiliary transmit adjacent channels a wireless communication transmission channel device, suppressing a wireless communication apparatus transmitting channel interference to adjacent channels, narrowing the protection bandwidth between the wireless communication transmission channel with adjacent channel devices, improved spectrum utilization efficiency; improve coverage performance of wireless communication transmission channel means adjacent channel.
