Wireless communication method, wireless communication apparatus, and wireless communication system
First Claim
1. A wireless communication method of a wireless communication system having a wireless base station, wireless terminal stations belonging to a first group which is capable of performing wireless communication while sharing a plurality of different frequency channels, and wireless terminal stations 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, the method comprising:
- communicating between at least one wireless terminal station belonging to the first group or the second group and the wireless base station by using a first frequency channel in the first communication period, performing direct communication between at least two wireless terminal stations belonging to the first group by using a second frequency channel without through the wireless base station in the first communication period; and
communicating between at least one wireless terminal station belonging to the first group and said wireless base station by using both the first frequency channel and the second frequency channel.

Abstract
In a wireless communication system having a wireless base station, wireless terminal stations belonging to a first group which performs wireless communication while sharing different frequency channels, and wireless terminal stations belonging to a second group which performs wireless communication by using one frequency channel, a first communication period and a second communication period is alternately repeated. In this system, a wireless terminal station belonging to the first or the second group communicates with the wireless base station by using a first frequency channel in the first communication period. Direct communication between two wireless terminal stations belonging to the first group by using a second frequency channel without through the wireless base station is performed in the first communication period. Then, a wireless terminal station belonging to the first group communicates with the wireless base station by using both the first and the second frequency channels.
