Abstract
【解決手段】データパケットを含むフレームを送出する装置が、それと同じチャネルの同じサブチャネルで装置間通信に係るネットワークコンテキスト情報も送出する(310)。他装置から送出されたフレームを捉えた装置はネットワークコンテキスト情報を複数フレームに亘り蓄積し(312)それに基づくフィードバック情報を送出元装置に供給する(314)。これにより、各装置は、自装置と通信可能な状態にある複数の他装置間で同一サブチャネルの使用に関しコンフリクトが発生することを防ぐ。
【選択図】図3
Description
Claims (4)
- 複数のサブチャネルを有するチャネルを介し複数の装置間でフレームを随時やりとりする通信システムであって、
各装置が、他装置に送りたいデータパケットを含むフレームを送出するときに、それと同じチャネルの同じサブチャネルでそのデータパケットに係るネットワークコンテキスト情報も送出するよう、且つ、他装置から送出されたフレームを捉えたときに、ネットワークコンテキスト情報を複数フレームに亘り蓄積して作成したフィードバック情報を当該他装置に供給するよう、構成されており、
上記フィードバック情報の供給により、各装置が、自装置と通信可能な状態にある複数の他装置間で同一サブチャネルの使用に関しコンフリクトが発生することを防ぐ通信システム。 - 請求項1記載の通信システムであって、フィードバック情報を装置間の直接通信により供給する通信システム。
- 請求項1記載の通信システムであって、フィードバック情報を他装置を介した装置間の間接通信により供給する通信システム。
- 請求項1記載の通信システムであって、フィードバック情報がコンフリクトの有無を示す情報を含む通信システム。
