Abstract
Description
図1は、本発明が適用されるLTEシステムの構造を示す図である。
図1を参照すれば、図示のように、LTEシステムの無線アクセスネットワークは、次世代基地局(Evolved Node B、以下、ENB、Node B、または基地局と称する)105,110,115,120と、MME(Mobility Management Entity)125と、S−GW(Serving−Gateway)130とで構成される。ユーザ端末(User Equipment、以下、UEまたは端末と称する)135は、ENB 105〜120及びS−GW 130を介して外部ネットワークに接続する。
図2を参照すれば、LTEシステムの無線プロトコルは、端末及びENBでそれぞれPDCP(Packet Data Convergence Protocol)205,240、RLC(Radio Link Control)210,235、MAC(Medium Access Control)215,230で構成される。PDCP(Packet Data Convergence Protocol)205,240は、IPヘッダー圧縮/復元などの動作を担当し、無線リンク制御(Radio Link Control、以下、RLCと称する)210,235は、PDCP PDU(Packet Data Unit)を適切なサイズに再構成し、ARQ動作などを行う。MAC 215,230は、1つの端末に構成された様々なRLC階層装置と接続され、RLC PDUをMAC PDUに多重化し、MAC PDUからRLC PDUを逆多重化する動作を行う。物理階層220,225は、上位階層データをチャネルコーディング及び変調し、OFDMシンボルを生成して無線チャネルで伝送するか、または無線チャネルを介して受信したOFDMシンボルを復調し、チャネルデコーディングし、上位階層に伝達する動作を行う。
図3を参照すれば、1つの基地局では、一般的に様々な周波数帯域にわたって多重キャリアが送出され、受信される。例えば、基地局305で中心周波数がf1のキャリア315と中心周波数がf3のキャリア310が送出されるとき、従来、1つの端末が前記2つのキャリアのうち1つのキャリアを利用してデータを送受信した。しかし、キャリア集積能力を有している端末は、同時に複数個のキャリアからデータを送受信することができる。基地局305は、キャリア集積能力を有している端末330に対しては、状況によってさらに多くのキャリアを割り当てることによって、前記端末330の伝送速度を高めることができる。
以下、本発明を説明するにあたって、端末が任意の順方向キャリアを介してデータを受信するか、または任意の逆方向キャリアを介してデータを伝送するというのは、前記キャリアを特徴づける中心周波数及び周波数帯域に対応するセルで提供する制御チャネルとデータチャネルを利用してデータを送受信することと同一の意味を有する。また、以下、本発明の実施形態は、説明の便宜のために、LTEシステムを仮定して説明されるが、本発明は、キャリア集積をサポートする各種無線通信システムに適用されることができる。
前記第1タイマーを使用する理由は、既存動作でSCellを活性化または不活性化させるとき、Activation/Deactivation MAC Control Elementを使用してどのSCellを活性化または不活性化させるかを通知したが、前記第1タイマーを使用することによって、Activation/Deactivation MAC Control Elementを使用せずに不活性化させる機能を提供することにある。
また、当該SCellを再活性化(reactivate:既に活性化状態であるが、前記SCellに該当するcorresponding bitが1に設定されたActivation/Deactivation MAC CEを受信する場合)させるActivation/Deactivation MAC CEを受信する度に再開始する(413)。前記第1タイマーは、mフレームの時間長さを有するタイマーであり、RRC(Radio Resource Control)階層のメッセージなどで設定可能である。
前記第2タイマーを使用する理由は、端末が当該SCellに対してサウンディング基準信号(SRS:Sounding Reference Symbol)伝送とCQI/PMI/RI/PTIの伝送を中断するために時間を与えるためのものであり、また、第2タイマーが満了する定められた時点に動作を中止し、基地局の性能に悪影響を及ぼさないようにすることに目的がある。前記CQI/PMI/RI/PTIに対する詳細な説明は、次の通りである。
−CQI(Channel Quality Indicator):チャネル品質指示子:ビットエラー確率10%を満たす推薦伝送フォーマット
−PMI(Precoding Matrix Index):プレコーディングマトリックスインデックス:closed−loop spatial multiplexingに使用されるインデックス
−RI(Rank Indicator):ランク指示子:推薦する伝送ランク
−PTI(Precoder Type Indication):プレコーダータイプ指示子
前記第2タイマーが始まった後に行う前記動作のうち、端末と基地局間の相互作用と無関係であり、端末が定められた時点に動作を中止しなければならない必要がない動作は、第2タイマーが満了する前に先に中断することができる。このような動作の例は、次の通りである。
−SCellからのPDCCH(Physical Downlink Control CHannel)モニタリング中断
−サウンディング基準信号(SRS:Sounding Reference Symbol)伝送中断
−チャネル状態情報報告(CSI reporting)中断
−CQI/PMI/RI/PTIの伝送中断
その後、第2タイマーが満了すれば、当該SCellは、不活性化される(419)。前記第2タイマーは、nサブフレームの時間を有し、nは、0以上の整数であり、固定された値の使用が可能である(例えば、n=8などが使用可能である)。第2タイマー満了後に、サウンディング基準信号(SRS:Sounding Reference Symbol)伝送とCQI/PMI/RI/PTIの伝送とを中断する。
端末は、8ビットのビットマップが含まれたActivation/Deactivation MAC CEを受信し、新規に活性化するSCellがあるか否かを確認して、もしあれば、当該SCellを活性化する(501)。より具体的には、端末は、MAC CEを受信する前に不活性化されているSCellを確認し、MAC CEを受信したとき、不活性化されているSCellに対してMAC CEのビットマップに「活性化」表示されているSCellを活性化する。前記Activation/Deactivation MAC CEは、活性化するSCellを決定する決定信号と称することができる。
端末は、上位階層605とデータなどを送受信し、制御メッセージ処理部607を介して制御メッセージを送受信し、送信時に、制御部609の制御によって多重化装置603を介して多重化後、送信機を介してデータを伝送し(601)、受信時に、制御部609の制御によって受信機で物理信号を受信した後(601)、逆多重化装置603で受信信号を逆多重化し、それぞれメッセージ情報によって上位階層605または制御メッセージ処理部607に伝達する。
提案する方式を使用すれば、搬送波集積技術を使用する場合、SCellを不活性化するとき、2つのタイマーを介して行うことによって、誤動作を防止し、正確な動作を行うことができる。
