Abstract
Description
上記の一次局および上記の少なくとも1つの二次局の一方である少なくとも1つの送信局から、上記の一次局および上記の少なくとも1つの二次局の他方である少なくとも1つの受信局に送信されるデータを、マッピングする工程と、
上記のデータマッピングに循環シフトを適用する工程であって、この循環シフトが、マッピングされるべきデータブロックの数に依存して調整される工程と
を含む方法が提案される。
Claims (8)
- 一次局と少なくとも1つの二次局との間で通信リソースを割り当てる方法であって、
前記一次局および前記少なくとも1つの二次局の一方である少なくとも1つの送信局から、前記一次局および前記少なくとも1つの二次局の他方である少なくとも1つの受信局に送信されるデータを、マッピングする工程と、
前記データマッピングに循環シフトを適用する工程であって、該循環シフトが、マッピングされるべきデータブロックの数に依存して調整される工程と
を含むことを特徴とする方法。 - 当該方法が、OFDM通信方法に適用され、前記循環シフトが、OFDM符号ごとに異なり、シフトの差の大きさが、分散化された態様でリソース要素群にマッピングされるべきデータブロックの数に依存することを特徴とする請求項1記載の方法。
- 第1のOFDM符号(すなわち符号インデックスがn=0であるOFDM符号)に適用されるシフトをS0、前記マッピングされるべきデータブロックの数をNdとして、n番目のOFDM符号に適用される前記シフトが、S(n)=S0+F(n,Nd)により表されることを特徴とする請求項1または2記載の方法。
- 前記循環シフトは、前記マッピングされるべきデータブロックの数が、サブキャリアの数の約数であるか否かに依存することを特徴とする請求項1から3いずれか1項記載の方法。
- 一続きの連続したリソース要素にマッピングされる群に、データ符号をグループ化する工程であって、1つの群に含まれる前記一続きの連続したリソース要素の数が、送信アンテナの数に等しくされる工程を、さらに含むことを特徴とする請求項1から4いずれか1項記載の方法。
- 前記循環シフトが、前記一次局のセルのIDの関数であることを特徴とする請求項1から5いずれか1項記載の方法。
- 前記循環シフトが、時間のシフト、コードのシフト、周波数のシフト、およびアンテナのシフトのうちの、少なくとも1つを包含していることを特徴とする請求項1から6いずれか1項記載の方法。
- 少なくとも1つの他の局との通信のためにリソースを割り当てる手段を含む無線局であって、少なくとも当該無線局から前記少なくとも1つの他の局に送信されるデータをマッピングする手段と、該データマッピングに循環シフトを適用する手段であって、該循環シフトが、マッピングされるべきデータブロックの数に依存して調整される手段とを含むことを特徴とする無線局。
