Description
本実施の形態では、ユーザの回線品質情報に応じて適応変調が適用される場合に、ユーザデータが送信されるデータCHのランク数に応じたランクオフセットを用いて、制御情報の符号化率を設定する場合について説明する。制御情報は、例えば、ACK/NACK、RI、CQI等であり、制御情報は、ユーザデータと時間多重されて、端末装置(以下「端末」と省略する)から基地局装置(以下「基地局」と省略する)に送信される。
実施の形態1では、データCHがランク送信される場合に、データCHのランク数に応じたランクオフセットを用いて、制御情報の符号化率を設定する場合について説明した。本実施の形態では、データCH及び制御CHがランク送信される場合に、データCHのランク数と制御CHのランク数との組み合わせに基づいたランクオフセットを用いて、制御情報の符号化率を設定する場合について説明する。
つまり、符号化率設定部122aは、ユーザの回線品質情報に応じて適応的に設定されるユーザデータの符号化率を基準値とし、ユーザデータと時間多重される制御情報の種類、及び、データCHのランク数と制御CHのランク数との組み合わせに応じて基準値を補正し、補正後の基準値を、制御情報の符号化率とするようにした。例えば、ユーザデータと時間多重される制御情報の符号化率R’controlを、ユーザデータの符号化率Rdataと、制御情報毎のPUSCHオフセットΔPUSCHoffsetと、データCHのランク数に応じたランクオフセットΔRANKoffsetにより、式(4)を用いて設定する。
