（本発明の第１の実施形態に係る移動通信システムの構成）
　図１乃至図１０を参照して、本発明の第１の実施形態に係る移動通信システムの構成について説明する。本実施形態に係る移動通信システムは、ＬＴＥ-Ａｄｖａｎｃｅｄ方式の移動通信システムである。 (Configuration of mobile communication system according to the first embodiment of the present invention)
The configuration of the mobile communication system according to the first embodiment of the present invention will be described with reference to FIG. 1 to FIG. The mobile communication system according to the present embodiment is an LTE-Advanced mobile communication system.
　図１に示すように、本実施形態に係る移動通信システムでは、移動局ＵＥは、無線基地局ｅＮＢに対して、ＰＵＣＣＨ（Ｐｈｙｓｉｃａｌ　Ｕｐｌｉｎｋ　Ｃｏｎｔｒｏｌ　Ｃｈａｎｎｅｌ、物理上りリンク制御チャネル）を介して制御信号を送信し、ＰＵＳＣＨ（Ｐｈｙｓｉｃａｌ　Ｕｐｌｉｎｋ　Ｓｈａｒｅｄ　Ｃｈａｎｎｅｌ、物理上りリンク共有チャネル）を介してデータ信号を送信するように構成されている。 As shown in FIG. 1, in the mobile communication system according to the present embodiment, the mobile station UE transmits a control signal to the radio base station eNB via a PUCCH (Physical Uplink Control Channel, physical uplink control channel). The data signal is transmitted via the PUSCH (Physical Uplink Shared Channel, physical uplink shared channel).
　また、本実施形態に係る移動通信システムでは、無線基地局ｅＮＢは、移動局ＵＥに対して、ＰＤＣＣＨ（Ｐｈｙｓｉｃａｌ　Ｄｏｗｎｌｉｎｋ　Ｃｏｎｔｒｏｌ　Ｃｈａｎｎｅｌ、物理下りリンク制御チャネル）を介して制御信号を送信し、ＰＤＳＣＨ（Ｐｈｙｓｉｃａｌ　Ｄｏｗｎｌｉｎｋ　Ｓｈａｒｅｄ　Ｃｈａｎｎｅｌ、物理下りリンク共有チャネル）を介してデータ信号を送信するように構成されている。 Further, in the mobile communication system according to the present embodiment, the radio base station eNB transmits a control signal to the mobile station UE via PDCCH (Physical Downlink Control Channel, physical downlink control channel), and PDSCH (Physical). A data signal is transmitted via a Downlink Shared Channel (physical downlink shared channel).
　また、図２に示すように、本実施形態に係る移動通信システムでは、搬送周波数Ｆ１乃至Ｆ５の複数のＣＣが用いられるように構成されている。ここで、本実施形態に係る移動通信システムでは、移動局ＵＥは、所定数のＣＣ（図２の例では、例えば、搬送周波数Ｆ１乃至Ｆ３の３つのＣＣ）を用いたＣＡを行うことができる。 Further, as shown in FIG. 2, the mobile communication system according to the present embodiment is configured such that a plurality of CCs having carrier frequencies F1 to F5 are used. Here, in the mobile communication system according to the present embodiment, the mobile station UE can perform CA using a predetermined number of CCs (in the example of FIG. 2, for example, three CCs of the carrier frequencies F1 to F3). .
　図３に示すように、無線基地局ｅＮＢは、送信部１１と、受信部１２と、制御部１３とを具備している。 As illustrated in FIG. 3, the radio base station eNB includes a transmission unit 11, a reception unit 12, and a control unit 13.
　送信部１１は、移動局ＵＥに対して、ＰＤＳＣＨを介して、ＲＲＣ（Ｒａｄｉｏ　Ｒｅｓｏｕｒｃｅ　Ｃｏｎｔｒｏｌ）情報要素として、「ＭｅａｓＣｏｎｆｉｇ」を送信するように構成されている。 The transmission unit 11 is configured to transmit “MeasConfig” as an RRC (Radio Resource Control) information element to the mobile station UE via the PDSCH.
　図４に、かかる「ＭｅａｓＣｏｎｆｉｇ」に含まれる情報要素の一例を示す。 FIG. 4 shows an example of information elements included in the “MeasConfig”.
　ここで、送信部１１は、情報要素「ＭｅａｓＯｂｊｅｃｔＴｏＲｅｍｏｖｅＬｉｓｔ」及び「ＭｅａｓＯｂｊｅｃｔＴｏＡｄｄＭｏｄＬｉｓｔ」によって、移動局ＵＥにおける測定対象の周波数を指定するように構成されている。 Here, the transmission unit 11 is configured to specify the frequency to be measured in the mobile station UE by the information elements “MeasObjectToRemoveList” and “MeasObjectToAddModList”.
　また、送信部１１は、情報要素「ＲｅｐｏｒｔＣｏｎｆｉｇＴｏＲｅｍｏｖｅＬｉｓｔ」や「ＲｅｐｏｒｔＣｏｎｆｉｇＴｏＡｄｄＭｏｄＬｉｓｔ」によって、移動局ＵＥにおける測定報告（Ｍｅａｓｕｒｅｍｅｎｔ　Ｒｅｐｏｒｔ）の送信条件を指定するように構成されている。 Further, the transmission unit 11 is configured to specify the transmission condition of the measurement report (Measurement Report) in the mobile station UE by the information elements “ReportConfigToRemoveList” and “ReportConfigToAddModList”.

　一方、「ｇａｐＯｆｆｓｅｔ」に「ｇｐ１」が設定されている場合、測定ギャップの周期は「８０ｍｓ」となり、測定ギャップの開始位置は「ＩＮＴＥＧＥＲ」に設定されている値（０～７９）によって特定されるサブフレームとなる。 On the other hand, when “gp1” is set in “gapOffset”, the period of the measurement gap is “80 ms”, and the start position of the measurement gap is specified by the value (0 to 79) set in “INTERGER”. It becomes a subframe.
　なお、ＬＴＥ方式（Ｒｅｌ.８/Ｒｅｌ.９）に対応している移動局ＵＥは、ＣＡに対応していないため、すなわち、複数のＣＣを用いて通信を行うことができないため、無線基地局ｅＮＢは、「ＭｅａｓＧａｐＣｏｎｆｉｇ」において、測定ギャップを設定すべきＣＣを特定する必要がない。 In addition, since the mobile station UE corresponding to the LTE scheme (Rel. 8 / Rel. 9) does not support CA, that is, cannot communicate using a plurality of CCs, the radio base station The eNB does not need to specify a CC for which a measurement gap should be set in “MeasGapConfig”.
　これに対して、送信部１１は、ＬＴＥ方式（Ｒｅｌ.１０）に対応している移動局ＵＥに対して、情報要素「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０（図４に示すＢ）」によって、移動局ＵＥにおいて設定すべき測定ギャップを指定するように構成されている。 On the other hand, the transmission unit 11 sets, in the mobile station UE, the information element “MeasGapConfigList-r10 (B shown in FIG. 4)” for the mobile station UE corresponding to the LTE scheme (Rel. 10). It is configured to specify the measurement gap to be performed.
　ここで、ＬＴＥ方式（Ｒｅｌ.１０）に対応している移動局ＵＥが、ＣＡを行っている場合にのみ、送信部１１は、「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０（図４に示すＢ）」によって、移動局ＵＥにおいて設定すべき測定ギャップを指定するように構成されていてもよい。 Here, only when the mobile station UE corresponding to the LTE scheme (Rel. 10) is performing CA, the transmission unit 11 uses the “MeasGapConfigList-r10 (B shown in FIG. 4)” as a mobile station. It may be configured to specify a measurement gap to be set in the UE.
　すなわち、ＬＴＥ方式（Ｒｅｌ.１０）に対応している移動局ＵＥが、ＣＡを行っていない場合には、送信部１１は、「ＭｅａｓＧａｐＣｏｎｆｉｇ（図４に示すＡ）」によって、移動局ＵＥにおいて設定すべき測定ギャップを指定するように構成されていてもよい。 That is, when the mobile station UE corresponding to the LTE scheme (Rel. 10) does not perform CA, the transmission unit 11 sets in the mobile station UE by “MeasGapConfig (A shown in FIG. 4)”. It may be configured to specify a measurement gap to be performed.
　具体的には、送信部１１は、図６に示すように、「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０」内の情報要素「ｃｃ-ｉｄ」に、測定ギャップを設定すべきＣＣの識別情報を指定するように構成されている。 Specifically, as illustrated in FIG. 6, the transmission unit 11 is configured to specify the identification information of the CC in which the measurement gap is to be set in the information element “cc-id” in “MeasGapConfigList-r10”. ing.
　なお、「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０」に設定される情報要素「ＭｅａｓＧａｐＣｏｎｆｉｇ」は、図５に示す情報要素「ＭｅａｓＧａｐＣｏｎｆｉｇ」と同一である。 The information element “MeasGapConfig” set in “MeasGapConfigList-r10” is the same as the information element “MeasGapConfig” shown in FIG.
　したがって、送信部１１は、「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０」内の情報要素「ｃｃ-ｉｄ」及び「ＭｅａｓＧａｐＣｏｎｆｉｇ」によって、ＣＣと測定ギャップ（周期及び開始位置）との組み合わせを指定することによって、移動局ＵＥにおいて設定すべき測定ギャップを指定することができる。 Therefore, the transmission unit 11 specifies the combination of CC and measurement gap (cycle and start position) by the information elements “cc-id” and “MeasGapConfig” in “MeasGapConfigList-r10”, thereby allowing the mobile station UE to The measurement gap to be set can be specified.
　なお、図６の例では、「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０」には、最大で８個のＣＣと測定ギャップ（周期及び開始位置）との組み合わせが設定可である。 In the example of FIG. 6, “MeasGapConfigList-r10” can set a combination of a maximum of eight CCs and measurement gaps (period and start position).
　また、「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０」で指定される「ＭｅａｓＧａｐＣｏｎｆｉｇ」は、複数のＣＣで共通であってもよい。すなわち、同じ測定ギャップの周期と開始位置が、複数のＣＣに共通に適用されてもよい。また、測定ギャップの開始位置が、ＣＣごとに固定的にずれるように構成されていてもよい。 In addition, “MeasGapConfig” specified by “MeasGapConfigList-r10” may be common to a plurality of CCs. That is, the same measurement gap period and start position may be commonly applied to a plurality of CCs. Further, the start position of the measurement gap may be configured to be fixedly shifted for each CC.
　受信部１２は、移動局ＵＥによって送信された「Ｍｅａｓｕｒｅｍｅｎｔ　Ｒｅｐｏｒｔ」を受信するように構成されている。 The receiving unit 12 is configured to receive “Measurement Report” transmitted by the mobile station UE.
　制御部１３は、受信部１２によって受信された「Ｍｅａｓｕｒｅｍｅｎｔ　Ｒｅｐｏｒｔ」に基づいて、移動局ＵＥがハンドオーバすべきであるか否かについて判定するように構成されている。 The control unit 13 is configured to determine whether or not the mobile station UE should be handed over based on the “Measurement Report” received by the receiving unit 12.
　また、制御部１３は、送信部１１に対して、移動局ＵＥがＬＴＥ方式（Ｒｅｌ.１０）に対応しているか否かについて、或いは、移動局ＵＥがＣＡを行っているか否かについて通知するように構成されている。 Further, the control unit 13 notifies the transmission unit 11 as to whether or not the mobile station UE is compatible with the LTE scheme (Rel. 10), or whether or not the mobile station UE is performing CA. It is configured as follows.
　図７に示すように、移動局ＵＥは、受信部２１と、測定部２２と、送信部２３とを具備している。 As shown in FIG. 7, the mobile station UE includes a receiving unit 21, a measuring unit 22, and a transmitting unit 23.
　受信部２１は、無線基地局ｅＮＢによって送信された「ＭｅａｓＣｏｎｆｉｇ」を受信するように構成されている。 The receiving unit 21 is configured to receive “MeasConfig” transmitted by the radio base station eNB.
　測定部２２は、無線基地局ｅＮＢによって送信された「ＭｅａｓＣｏｎｆｉｇ」に基づいて、無線基地局ｅＮＢによって指定された測定（Ｍｅａｓｕｒｅｍｅｎｔ）を行うように構成されている。 The measurement unit 22 is configured to perform measurement specified by the radio base station eNB based on “MeasConfig” transmitted by the radio base station eNB.
　具体的には、測定部２２は、「ＭｅａｓＣｏｎｆｉｇ」によって指定された測定ギャップにおいて、「ＭｅａｓＣｏｎｆｉｇ」によって指定された測定対象の周波数における測定を行うように構成されている。 Specifically, the measurement unit 22 is configured to perform measurement at the measurement target frequency designated by “MeasConfig” in the measurement gap designated by “MeasConfig”.
　例えば、移動局ＵＥが、搬送周波数Ｆ１乃至Ｆ３のキャリアを用いたＣＡを行っている場合に、「ＭｅａｓＣｏｎｆｉｇ」によって測定対象の周波数として「Ｆ４」が指定され、「ＭｅａｓＣｏｎｆｉｇ」によって搬送周波数Ｆ２のＣＣにおいて測定ギャップを設定すべきであると指定された場合（すなわち、「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０」内に「ｃｃ-ｉｄ＝Ｆ２」が設定されている場合）には、測定部２２は、図８に示すように、搬送周波数Ｆ２のＣＣにおける測定ギャップにおいて、周波数Ｆ４における測定を行うように構成されている。 For example, when the mobile station UE performs CA using carriers of the carrier frequencies F1 to F3, “F4” is designated as the frequency to be measured by “MeasConfig”, and the CC of the carrier frequency F2 is designated by “MeasConfig” 8 indicates that the measurement gap should be set (that is, when “cc-id = F2” is set in “MeasGapConfigList-r10”), the measurement unit 22 is shown in FIG. As described above, the measurement at the frequency F4 is performed in the measurement gap in the CC of the carrier frequency F2.
　また、移動局ＵＥが、搬送周波数Ｆ１乃至Ｆ３のキャリアを用いたＣＡを行っている場合に、「ＭｅａｓＣｏｎｆｉｇ」によって測定対象の周波数として「Ｆ４」及び「Ｆ５」が指定され、「ＭｅａｓＣｏｎｆｉｇ」によって搬送周波数Ｆ２のＣＣにおいて測定ギャップを設定すべきであると指定された場合（すなわち、「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０」内に「ｃｃ-ｉｄ＝Ｆ２」が設定されている場合）には、測定部２２は、図９に示すように、搬送周波数Ｆ２のＣＣにおける測定ギャップにおいて、周波数Ｆ４及びＦ５における測定を行うように構成されている。 In addition, when the mobile station UE performs CA using carriers of the carrier frequencies F1 to F3, “F4” and “F5” are designated as measurement target frequencies by “MeasConfig”, and carried by “MeasConfig”. When it is specified that the measurement gap should be set in the CC of the frequency F2 (that is, when “cc-id = F2” is set in “MeasGapConfigList-r10”), the measurement unit 22 As shown in FIG. 9, the measurement is performed at the frequencies F4 and F5 in the measurement gap at the CC of the carrier frequency F2.
　さらに、移動局ＵＥが、搬送周波数Ｆ１乃至Ｆ３のキャリアを用いたＣＡを行っている場合に、「ＭｅａｓＣｏｎｆｉｇ」によって測定対象の周波数として「Ｆ４」及び「Ｆ５」が指定され、「ＭｅａｓＣｏｎｆｉｇ」によって搬送周波数Ｆ２及びＦ３のＣＣにおいて測定ギャップを設定すべきであると指定された場合（すなわち、「ＭｅａｓＧａｐＣｏｎｆｉｇＬｉｓｔ-ｒ１０」内に「ｃｃ-ｉｄ＝Ｆ２」及び「ｃｃ-ｉｄ＝Ｆ３」が設定されている場合）には、測定部２２は、図１０に示すように、搬送周波数Ｆ２及びＦ３のＣＣにおける測定ギャップにおいて、周波数Ｆ４及びＦ５における測定を行うように構成されている。 Further, when the mobile station UE performs CA using carriers of the carrier frequencies F1 to F3, “F4” and “F5” are designated as measurement target frequencies by “MeasConfig”, and carried by “MeasConfig”. When it is specified that the measurement gap should be set in the CCs of the frequencies F2 and F3 (that is, “cc-id = F2” and “cc-id = F3” are set in “MeasGapConfigList-r10”) In the case), the measurement unit 22 is configured to perform measurements at the frequencies F4 and F5 in the measurement gap in the CC of the carrier frequencies F2 and F3, as shown in FIG.
　ここで、測定部２２は、ＣＡ対象のＣＣから特定のＣＣが削除された場合には、かかる特定のＣＣに適用されていた測定ギャップについては暗示的に解除するように構成されていてもよい。 Here, when a specific CC is deleted from a CA target CC, the measurement unit 22 may be configured to implicitly cancel a measurement gap that has been applied to the specific CC. .
　送信部２３は、上述の測定結果が「ＭｅａｓＣｏｎｆｉｇ」によって指定された報告条件を満たした場合、無線基地局ｅＮＢに対して、かかる測定結果を含む「Ｍｅａｓｕｒｅｍｅｎｔ　Ｒｅｐｏｒｔ」を送信するように構成されている。 The transmission unit 23 is configured to transmit “Measurement Report” including the measurement result to the radio base station eNB when the above-described measurement result satisfies the reporting condition specified by “MeasConfig”. .
