Abstract
【解決手段】無線マルチキャリア通信の方法は、アップリンク上の副搬送を、重なり合っていないグループへ分割することと、それぞれホッピングの継続期間および重なり合っていないグループを含んでいる時間周波数ブロックを割り振ることと、直交符号の異なる組を各ユーザに割り当てることと、各ユーザのデータ(またはパイロット)シンボルを、割り振られた時間周波数ブロックにわたって拡散することであって、各ユーザのデータ(またはパイロット)シンボルを、各ユーザに割り当てられた直交符号の異なる組を使用して拡散し、各データ(またはパイロット)シンボルを、時間周波数ブロック内の変調シンボルにマップし、マップされたシンボルに基づいて、直交波形を生成し、直交波形を送信する。

Description
本発明は、概ね、通信、より具体的には、無線通信システムの直交アップリンクにおけるマルチキャリア符号分割多元接続(multi-carrier code division multiple access, MC-CDMA)を支援する技術に関する。
周波数ホッピング スペクトル拡散(frequency hopping spread spectrum, FHSS)通信システムにおいて、データは、異なる周波数サブバンドまたは副搬送波上で、異なる時間間隔において送信される。この時間間隔は、“ホップ期間(hop periods)”とも呼ばれる。これらの周波数サブバンドは、直交周波数分割多重化(orthogonal frequency division multiplexing, OFDM)、他のマルチキャリア変調技術、または何か他の構成によって与えられ得る。FHSSを使用するとき、データ送信は、サブバンドからサブバンドへ擬似ランダムにホップする。このホッピングは、周波数ダイバーシティを与え、データ送信が、狭帯域干渉、ジャミング、フェージング、等のような有害な経路の影響に、より良く耐えることを可能にする。
テム200内の端末の1つである。単純化のために、端末22Oxの送信機部分のみが、図2に示されている。
