Description
本出願は、2017年6月10日に出願した米国仮特許出願第62/517,916号、2017年6月19日に出願した米国仮特許出願第62/522,044号、および2018年6月7日に出願した米国特許出願第16/003,047号の利益および優先権を主張するものである。3つのすべての出願は、以下に完全に記載されるかのように、すべての適用可能な目的で、その全体が参照により本明細書に組み込まれる。
図1は、本開示の態様が実行される場合がある例示的なワイヤレス通信ネットワーク100を示す。たとえば、ワイヤレス通信ネットワーク100は、ニューラジオ(NR)または5Gネットワークであり得る。NRネットワークは、本開示のいくつかの態様に従って、いくつかの送信のために低密度パリティチェック(LDPC)コーディングを使用することができる。たとえば、ダウンリンク上の基地局(BS)110またはアップリンク上のユーザ機器(UE)120などの送信デバイスは、ワイヤレス通信ネットワーク100内の受信デバイスに対する送信のために情報ビットを符号化することができる。送信デバイスは、LDPCコードを使用して、いくつかの送信のために情報ビットを符号化する。LDPCコードに関連する基本グラフは、基本グラフの下側部分の中にペアワイズの行直交性を有し得る。ダウンリンク上のUE120またはアップリンク上のBS110などの受信デバイスは、送信デバイスから符号化された送信を受信し、送信を復号して、情報を取得する。受信デバイスは、よりフレキシブルなデコーダスケジューリングのためにデコーダ内でペアワイズの行直交性を活用し得る。
(たとえば、NRなどの)多くの通信システムは誤り訂正コードを使用する。誤り訂正コードは、一般に、データストリーム内に冗長性を取り入れることによって、これらのシステム内の(たとえば、空気媒体上で)情報転送の固有の不信頼性を補償する。低密度パリティ検査(LDPC)コードは、反復コーディングシステムを使用する1つのタイプの誤り訂正コードである。Gallagerコードは、「正規」LDPCコードの例である。正規LDPCコードは、そのパリティチェック行列(PCM)の要素Hの大部分が「0」である線形ブロックコードである。
ニューラジオ(NR)において、いくつかのチャネルのチャネルコーディングのために、低密度パリティチェック(LDPC)が使用される。図7〜図10に関して上記で説明したように、LDPCコードは、変数ノードとチェックノードとを含む基本グラフによって定義され、基本グラフは、変数ノードに対応する列とチェックノードに対応する行とを有する、対応するパリティチェック行列(PCM)によって表され得る。基本グラフ内のエッジは、PCM内にエントリを有する。準巡回(quasi-cyclic)LDPCコードは、第i番目の列および第j番目の行に対して、PCM内の非ゼロエントリ内に整数の巡回リフティング値Vi,jを有する。巡回リフティング値は、基本グラフがリフトされたグラフを取得するためにリフトされるとき、エッジの巡回置換に対応する。リフトの数Zは、リフティング値またはリフティングサイズ値である。様々なブロック長をサポートするために、基本グラフに対する様々なZ値が使用される。それぞれのサポートされるリフトに対して、リフティングサイズおよび巡回リフティング値に応じて、シフト係数が計算される:
Pi,j=f(Vi,j, Z)
LDPC符号化の前に短縮が適用され得る。システマティックビットがパンクチャリングされ得る。
