本発明は一般的には通信に関する。より詳細には媒体アクセス制御に関する。
上述したように、ここに詳述した種々の実施例は既存システムと互換性があるように展開されるかもしれない。IEEE802.11(e)の機能セット(先行の802.11標準と後方互換性がある)は、先行する標準に導入された機能と共に、本節で要約される種々の機能を含む。これらの機能の詳述に対してはそれぞれのIEEE802.11標準を参照のこと。
上述したように、先行のMACの種々の非効率的機能は後続版に提示された。例えば、64Mbpsに対して11Mbps用に設計された非常に長いプリアンブルは非効率を招く。レートの上昇に従ってMACプロトコルデータユニット(MPDU)は縮小し続けるため、種々のフレーム間隔および/またはプリアンブルを一定に保つことは関連するチャネル利用の減少を意味する。例えば、高データレートのMIMO MPDU送信信号は72μsecのプリアンブルがある802.11(g)に比べ、わずか数マイクロセカンドの長さかもしれない。SIFS、信号拡張および/またはプリアンブルのような遅延を除去または減少させると、スループットおよびチャネル利用度が向上するだろう。
ここに詳述する実施例において、ネットワークは実際のアクセスポイントがある場合または無い場合の動作をサポートするかもしれない。実際のAPが存在する場合、それは例えば有線の太いパイプ接続(例えばケーブル、ファイバ、DSLもしくはT1/T3、イーサネット)または家庭娯楽用サーバに接続されるかもしれない。この場合、実際のAPはネットワーク内の装置の間を流れるデータの大部分のためのソースとシンクであるかもしれない。
上述したように、ピアツーピア(または、簡単に「ピア-ピア」と呼ばれる)送信により、1つのSTAは、データを最初にAPに送ることなく、直接別のSTAに送信できる。ここに詳述された種々の態様はピアツーピア送信と共に用いるために採用されるかもしれない。一実施例において、さらに先で詳述するように、直接リンクプロトコル(DLP)が、適応されるかもしれない。図17にシステム100内のピアツーピア通信の例を図示する。この例において、図1に図示したシステム100と同様であるかもしれないシステム100は1UTから別のUTへの直接送信ができるように適応される(この例においては、UT106AとUT106Bとの間の伝送が例示されている)。UT106は、ここに詳述するように、WLAN120上のAP104との通信を直接実行するかもしれない。
ここに詳述されるように、説明した種々の実施例は既存システムの改善を提供する。それにも拘わらず、既に現存する既存システムの広い展開を考えると、システムが現在の既存システムおよび/または既存ユーザ端末との後方互換性を持つことは望ましいかもしれない。ここに用いられるように、用語「新クラス」は既存システムと区別するために用いられる。新クラスシステムは、ここに詳述した態様または機能の1つ以上を組み込むかもしれない。新クラスシステムの例は、図35−52を参照して以下で説明するMIMO OFDMシステムである。さらに、以下に詳述する新クラスシステムと既存システムの相互運用のための態様は、ここに詳述した任意の特定の改良がそのようなシステムに含まれているか否かに関係なく、これから展開される他のシステムにも適用できる。
既存システムとの相互運用性のための方法の他の実施例を図53に図示する。図15を参照して上で詳述したようなMACフレームの例1500を示す。スロット区間5310が定められているスロットモードが導入される。スロット区間5310は、MIMOパイロット区間5315およびスロットギャップ5320を含む。図示したようにパイロット5315は、EDCAのような規則に従って動作する他の端末(APを含む)による干渉からチャネルを確保するために挿入される。変更されたMACフレーム5330は、媒体の制御を保持するために挿入されたパイロット5315と共にMACフレーム1500を実質的に含む。当業者には明白であるように、図53は単に例示である。スロットモードは、種々の例をここに詳述したMACフレームのいずれかに組み込まれるかもしれない。
以下で詳述されるのは、追加的態様と同様に上で導入された種々の態様を例示する一実施例である。この例において、MIMOを用いた拡張802.11 WLANが例示される。種々のMACの拡張を、対応するデータおよびMAC層並びに物理層で用いるためのメッセージ構造と同様に詳述する。当業者はWLANの機能の例示的サブセットだけが開示されていることを認識し、ここの教示を種々のシステムとの相互運用性と同様に802.11の既存システムとの相互運用性に容易に適応させるだろう。
この一実施例において、柔軟性のあるフレーム集約が容易にされる。図35に1つの集約されたフレームの中に1つ以上のMACフレーム(または、フラグメント)のカプセル化を図示する。フレーム集約は、集約されたフレーム3520内の1つ以上のMACフレーム(またはフラグメント)3510のカプセル化を認める。フレーム集約は以下に詳述するヘッダ圧縮を組み込むかもしれない。集約MACフレーム3520はPSDU3530を形成する。このPSDUは単一のPPDUとして送信されるかもしれない。集約MACフレーム3520は、形式データ、管理または制御のカプセル化したフレーム(またはフラグメント)3510を含むかもしれない。プライバシーが動作中の場合、フレームのペイロードは暗号化されるかもしれない。暗号化されたフレームのMACフレームヘッダは「妨害無し」で送信される。
図36にMACヘッダ3680、それに続くフレーム本体3650(オクテットの可変数Nを含むかもしれない)およびフレームチェックシンボル(FCS)3655(この例では4オクテット)を含む既存MACフレーム3600を図示する。この従来技術のMACフレームフォーマットは802.11eで詳述されている。MACヘッダ3660はフレーム制御フィールド3610(2オクテット)、デュレーション/IDフィールド3615(2オクテット)、シーケンス制御フィールド3635(2オクテット)、およびQoS制御フィールド3645(2オクテット)を含む。さらに、4個のアドレスフィールド、アドレス1 3620、アドレス2 3625、アドレス3 3630、およびアドレス4 3640(それぞれ6オクテット)が含まれる。また、これらのアドレスはそれぞれTA、RA、SA、およびDAと呼ばれるかもしれない。TAは送信端末のアドレスである。RAは受信端末のアドレスである。SAは送信元端末のアドレスである。DAは受信先端末のアドレスである。
適応型調整機能(ACF)はHCCAおよびEDCAの拡張であり、MIMO PHYによって動作可能とされた高データレートでの動作に適した柔軟性、高能率、低待ち時間のスケジューリングされた動作を可能とするものである。図41にACFで使用するためのスケジューリングされたアクセス期間フレーム(SCAP)の一実施例を例示する。SCHEDメッセージ4120を用いて、APは、同時に1つ以上のAP−STA、STA−APまたはSTA−STAのTXOPを、スケジューリングされたアクセス期間として知られる期間4130にわたりスケジューリングする。これらのスケジューリングされた送信信号はスケジューリングされた送信信号4140として特定される。SCHEDメッセージ4120は上で詳述した既存HCCAポーリングの代替である。一実施例において、SCAPの最大許容値は4msecである。
SCHEDの受信誤りからの回復のためにAPは種々の手順を用いるかもしれない。例えば、STAがSCHEDメッセージを復号できない場合、TXOPを利用することはできないだろう。スケジューリングされたTXOPが割当てられた開始時刻に始まらない場合、APは、未使用のスケジューリングされたTXOPの開始後の1PIFSにおいて送信することによって、回復を開始するかもしれない。APは未使用のスケジューリングされたTXOPの期間をCAPとして用いるかもしれない。CAPの間、APは1つ以上のSTAに送信するか、またはSTAをポーリングするかもしれない。このポーリング信号はスケジューリングされたTXOPを見逃したSTAまたは別のSTA向けかもしれない。CAPは次のスケジューリングされたTXOPに先立って終了する。
上述したように、SCAPはFRACH送信信号に専用の部分、および/または、MIMO STAがEDCA手順を用いるかもしれない部分を含むかもしれない。これらの競合ベースのアクセス期間はSCAPに対するNAV設定によって保護されるかもしれない。
一般的にフレーム間間隔を縮減する種々の方法は上で詳述した。ここでは、本実施例におけるフレーム間間隔縮減に関するいくつかの例を例示する。スケジューリングされた送信について、TXOPの開始時刻はSCHEDメッセージ内で示される。送信STAは、媒体がアイドル状態あることを決定することなく、SCHEDメッセージに示された正確な開始時刻にスケジューリングされたTXOPを開始するかもしれない。上述したように、SCAPの間のスケジューリングされた連続したAP送信信号は最小のIFSなしで送信される。
図45に、図41を参照して導入し、さらに先で詳述するSCHEDメッセージを例示する。SCHEDメッセージ4120は、スケジューリングされたアクセス期間(SCAP)の期間に、1つ以上のAP−STA、STA−AP、およびSTA−STA TXOPを割当てる複数のポーリングメッセージである。SCHEDメッセージを用いて、ポーリングおよび競合オーバーヘッドを抑え、また不要IFSを除去できる。
図49に既存802.11 PPDU4970を図示する。このPPDUは、PLCPプリアンブル4975(12OFSMシンボル)、PLCPヘッダ4910、可変長PSDU4945、6ビットのテール4950、および可変長パッド4955を含む。PPDU4970の一部4960が、符号化率=1/2のBPSKを用いて送信されるSIGNALフィールド(1OFDMシンボル)、およびSIGNAL4980で示される変調フォーマットおよびレートで送信される可変長データフィールド4985を含む。PLCPヘッダ4910は、SIGNAL4980および16ビットのサービスフィールド4940を含む。(サービスフィールドはDATA4985に含まれ、そのフォーマットに従って送信される)。SINGNALフィールド4980はレート4915(4ビット)、確保したフィールド4920(1ビット)、長さ4925(12ビット)、パリティビット4930、およびテール4935(6ビット)を含む。
