First Claim
1. A system for forming a network for a plurality of wireless communication apparatuses in a self-organized distributed manner without having a relationship of a controlling station and a controlled station, in a communication environment provided with a plurality of channels, wherein each communication station sets a transmission pause period in accordance with whether a neighboring station is a neighbor station or a next neighbor station and in accordance with a channel used for transmission from the neighboring station at a transmission scheduled time of the neighboring station.

Abstract
A communication station forms a multi-channel self-organized distribution type wireless network effectively without providing an unnecessary transmission pause period. The communication station refers to neighbor apparatus information described in a beacon received from a neighbor station to judge whether or not a beacon transmission channel of a corresponding next neighbor station matches a transmission scheduled channel of its own. In a case where these channels match, a transmission pause period for the next neighbor station is provided and the transmission is postponed. Accordingly, blocking against the beacon reception from the next neighbor station by the neighbor station can be avoided and provision of an unnecessary transmission pause period is not required so that the throughput is improved.
