Description
"3GPP TS 25.309 V.6.6.0 FDD Enhanced Uplink Overall description Stage 2 (Release 6)"、3GPP、2006年3月
図1は、本実施形態に係る無線通信システム10の全体概略構成図である。図1に示すように、無線通信システム10は、無線基地局100、無線ネットワーク制御装置200(以下、RNC200)及び移動機300A,300Bによって構成される。なお、無線通信システム10に含まれる無線基地局や移動機の数は、図1に示す数に限定されない。
図2は、無線基地局100の機能ブロック構成図である。図2に示すように、無線基地局100は、無線信号送受信部101、ベースバンド信号処理部103、ネットワークI/F部105、パラメータ選択部107、通信制御部109及びテーブル格納部111を備える。なお、以下、本発明との関連がある部分について主に説明する。したがって、無線基地局100は、無線基地局100としての機能を実現する上で必須な、図示しない或いは説明を省略したブロック(電源部など)を備える場合があることに留意されたい。
(ii) Reference E-TFCI
(iii) Reference E-TFCI PowerOffset
(iv) E-DCH HARQ Offset
(v) Maximum Set of E-DPDCHs
(vi) E-TFCI Table Index
(vii) E-TTI
E-TFCI Table Index及びE-TTIは、送信パワーオフセットの演算に使用するE-TFCIのテーブルを定義(指定)するパラメータであり、送信パワーオフセットの演算には影響を与えない。なお、(1式)を用いた演算では、E-TFCI Table Index及びE-TTIによって、E-TFCIのテーブルが確定していることを前提とする。
図3は、RNC200の機能ブロック構成図である。図3に示すように、RNC200は、ネットワークI/F部201及びパラメータ通知部203を備える。なお、以下、本発明との関連がある部分について主に説明する。したがって、RNC200は、RNC200としての機能を実現する上で必須な、図示しない或いは説明を省略したブロック(電源部など)を備える場合があることに留意されたい。
次に、無線通信システム10の動作について説明する。具体的には、無線基地局100及びRNC200が移動機300Aの送信パワーを制御する動作について説明する。
無線通信システム10によれば、無線基地局100には、移動機300A(300B)が送信するE-DPDCHのE-TFCIと、βedとが対応付けられたE-TFCI/βedテーブルTBが格納される。このため、無線基地局100は、移動機300A(300B)との間において生起された呼毎にそれぞれのE-TFCIにおけるβedを演算し、それぞれのSGとE-TFCIとの対応テーブルを作成する必要がない。また、選択されたβedと対応付けられているE-TFCIに基づいて、SGの決定に用いられる所定パラメータを、既存の無線ネットワーク制御装置〜無線基地局間、及び無線ネットワーク制御装置〜移動機間のメッセージを用いて送受信することができる。
上述したように、本発明の一実施形態を通じて本発明の内容を開示したが、この開示の一部をなす論述及び図面は、本発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施の形態が明らかとなろう。
