Increase in the channel utilization level of efficiency in a wireless communication system with terminals with high throughput and existing terminals

摘要

A wireless communication method of a wireless communication system having a wireless base station (1), wireless terminal stations (2) belonging to a first group which is capable of performing wireless communication while sharing a plurality of different frequency channels, and wireless terminal stations (3) belonging to a second group which is capable of performing wireless communication by using one frequency channel, wherein a first communication period and a second communication period is alternately repeated. In this method, at least one wireless terminal station (2,3) belonging to the first group or the second group communicates with the wireless base station (1) by using a first frequency channel in the first communication period. Direct communication between at least two wireless terminal stations (2a,2b,2c) belonging to the first group by using a second frequency channel without through the wireless base station (1) is performed in the first communication period. Then, at least one wireless terminal station (2a,2b,2c) belonging to the first group communicates with the wireless base station (1) by using both the first frequency channel and the second frequency channel in the second communication period.
