A method for allowing wireless communication between an access point and a wireless station in a wireless communication network includes: providing at least one from a combination of a 2.4 GHz frequency band and a 5 GHz frequency band; providing a frequency band including a 6 GHz frequency band for allowing wireless data communication; assigning a first data communication channel having a first frequency bandwidth in the frequency band including the 6 GHz frequency band between the access point and the wireless station; and transmitting data packets between the access point and the wireless station via the first data communication channel in the frequency band including the 6 GHz frequency band. Each of the 2.4 GHz frequency band and the 5 GHz frequency band includes a plurality of subchannels having a first base frequency bandwidth of 20 MHz, and the frequency band including the 6 GHz frequency band includes a plurality of subchannels having a second base frequency bandwidth that is larger than the first base frequency bandwidth.
