Abstract
【解決手段】通信システムを介して相対的に大量の情報を搬送し、MIMOアンテナ・システムを活用できるようにするために、順方向リンク信号チャネルが提供され、通信システムがMIMOシステムのアンテナ素子のうちの任意の1つを使用してトラフィック情報を再送できるようにするスワッピング情報や、チャネル割当て情報が含まれる。さらに通信システムを介して相対的に大量の情報を搬送するように対処するために、逆方向リンク信号情報の形式は、(1)逆方向リンク信号情報が時分割多重化される、(2)逆方向リンク情報が相対的に高位の変調で変調される、および(3)逆方向リンク情報に追加のチャネルが提供される、という3つのメカニズムのうちの任意の1つまたは任意の組合せを使用して修正される。
