Description

移動局および無線基地局Mobile stations and radio base stations
　本発明は、移動局および無線基地局に関する。 The present invention relates to a mobile station and a radio base station.
　３ＧＰＰで仕様化が進められているＬＴＥ（Ｌｏｎｇ　Ｔｅｒｍ　Ｅｖｏｌｕｔｉｏｎ）-Ａｄｖａｎｃｅｄ方式の移動通信システムでは、「ＣＡ（Ｃａｒｒｉｅｒ　Ａｇｇｒｅｇａｔｉｏｎ）」を行うことが検討されている。 In the LTE (Long Term Evolution) -Advanced mobile communication system, which is being specified by 3GPP, it is considered to perform "CA (Carrier Aggregation)".
　ＬＴＥ-Ａｄｖａｎｃｅｄ方式の移動通信システムでは、移動局ＵＥは、１つの無線基地局ｅＮＢとの間で、異なる周波数帯域の複数の「Ｃｏｍｐｏｎｅｎｔ　Ｃａｒｒｉｅｒ（ＣＣ）」を同時に用いて、ＣＡを行うことができるように構成されている。 In the LTE-Advanced mobile communication system, the mobile station UE can perform CA with a single radio base station eNB using a plurality of “Component Carriers (CC)” in different frequency bands at the same time. It is configured as follows.
　また、ＣＡが行われる場合、移動局ＵＥは、無線基地局からの指示に応じて、複数のＣＣの中から、１つをＰＣＣ（Ｐｒｉｍａｒｙ　Ｃｏｍｐｏｎｅｎｔ　Ｃａｒｒｅｒ）として設定し、その他をＳＣＣ（Ｓｅｃｏｎｄａｒｙ　Ｃｏｍｐｏｎｅｎｔ　Ｃａｒｒｅｒ）として設定するように構成されている。 In addition, when CA is performed, the mobile station UE sets one of a plurality of CCs as a PCC (Primary Component Carrer) and the other as a SCC (Secondary Component Carrer) in response to an instruction from the radio base station. ) Is configured to set as.
　また、ＬＴＥ-Ａｄｖａｎｃｅｄ方式では、ＣＡを行うことができる周波数帯域の組み合わせ（「Ｂａｎｄ　Ｃｏｍｂｉｎａｔｉｏｎ」）に加えて、かかる周波数帯域の組み合わせに対して、該当周波数帯域の組み合わせに含まれる１つ又は複数のＣＣの帯域幅の組み合わせ（「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」）を規定することが提案されている（非特許文献１～４参照）。 In addition, in the LTE-Advanced scheme, in addition to the combination of frequency bands that can perform CA ("Band Combination"), one or more of the combinations of the frequency bands are included in the combination of the corresponding frequency bands. It has been proposed to define CC bandwidth combinations ("Supported CC Bandwidth Combinations") (see Non-Patent Documents 1 to 4).
　しかしながら、非特許文献３及び４で示される方法では、既存のＬＴＥ-Ａｄｖａｎｃｅｄ方式では、移動局ＵＥは、自身が対応する「Ｂａｎｄ　Ｃｏｍｂｉｎａｔｉｏｎ」において、自身が対応する「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」に含まれる帯域幅よりも大きい帯域幅のＣＣで運用された場合には、ＣＡを行うことができないという問題点があった。 However, in the methods shown in Non-Patent Documents 3 and 4, in the existing LTE-Advanced scheme, the mobile station UE is included in the “Supported CC Bandwidth Combinations” that it supports in the “Band Combination” that it supports. When operated with a CC having a bandwidth larger than the bandwidth, there is a problem that CA cannot be performed.
　特に、ＬＴＥ-Ａｄｖａｎｃｅｄ方式の移動通信システムにおいて、特定の周波数帯域において、移動局ＵＥは、対象としないＣＣの帯域幅の組み合わせにて運用が行われていた場合に、かかる特定の周波数帯域内のＣＣを用いてＣＡを行うことができていたにも関わらず、かかる拡張の後には、かかる特定の周波数帯域内のＣＣを用いてＣＡを行うことができなくなってしまうという問題点があった。 In particular, in a mobile communication system of the LTE-Advanced scheme, in a specific frequency band, when the mobile station UE is operated with a combination of CC bandwidths not targeted, the mobile station UE In spite of having been able to perform CA using CC, there has been a problem that after such expansion, CA cannot be performed using CC within the specific frequency band.
　かかる場合、具体的には、移動局ＵＥは、対象としないＣＣの帯域幅の組み合わせで運用が行われていた場合に、かかる特定の周波数帯域において、報知情報を受信することができなくなってしまう可能性があった。 In such a case, specifically, when the mobile station UE is operated with a combination of CC bandwidths that are not targeted, the mobile station UE cannot receive broadcast information in the specific frequency band.

（本発明の第１の実施形態に係る移動通信システム）
　図１乃至図６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。 (Mobile communication system according to the first embodiment of the present invention)
With reference to FIG. 1 thru | or FIG. 6, the mobile communication system which concerns on the 1st Embodiment of this invention is demonstrated. The mobile communication system according to the present embodiment is an LTE-Advanced mobile communication system.
　なお、本実施形態に係る移動通信システムにおいて、移動局ＵＥは、無線基地局ｅＮＢとの間で、周波数帯域Ｆ１のＣＣ及び周波数帯域Ｆ２のＣＣを同時に用いて、信号の送受信を行うことができるように構成されている、すなわち、ＣＡを行うことができるように構成されている。 In the mobile communication system according to the present embodiment, the mobile station UE can transmit and receive signals to and from the radio base station eNB by simultaneously using the CC of the frequency band F1 and the CC of the frequency band F2. That is, it is comprised so that CA can be performed.
　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に対して、周波数帯域Ｆ１のＣＣが「ＰＣＣ」として設定され、周波数帯域Ｆ２のＣＣが「ＳＣＣ」として設定されているものとする。 As shown in FIG. 1, in the mobile communication system according to the present embodiment, the CC of the frequency band F1 is set as “PCC” and the CC of the frequency band F2 is set as “SCC” for the mobile station UE. It shall be.
　図２に示すように、移動局ＵＥは、管理部１１と、送信部１２と、受信部とを具備している。 As shown in FIG. 2, the mobile station UE includes a management unit 11, a transmission unit 12, and a reception unit.
　管理部１１は、ＣＡを行うことができる周波数帯域の組み合わせ（図３に示す「Ｅ-ＵＴＲＡ　Ｂａｎｄ　Ｃｏｍｂｉｎａｔｉｏｎ」）のうち、移動局ＵＥが対応する周波数帯域の組み合わせを管理するように構成されている。 The management unit 11 is configured to manage a combination of frequency bands that the mobile station UE corresponds to among combinations of frequency bands that can perform CA (“E-UTRA Band Combination” illustrated in FIG. 3). .
　また、管理部１１は、移動局ＵＥが対応する周波数帯域の組み合わせにおいて、ＣＡを行うことができる周波数帯域内のＣＣの帯域幅の組み合わせ（図３に示す「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」）のうち、移動局ＵＥが対応する帯域幅の組み合わせを管理するように構成されている。 Further, the management unit 11 includes a combination of CC bandwidths within a frequency band in which CA can be performed in a combination of frequency bands supported by the mobile station UE ("Supported CC Bandwidth Combinations" illustrated in FIG. 3). The mobile station UE is configured to manage a combination of corresponding bandwidths.
　例えば、本実施形態に係る移動通信システムでは、図３に示すように、「Ｅ-ＵＴＲＡ　Ｂａｎｄ　Ｃｏｍｂｉｎａｔｉｏｎ」及び「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」が規定されていてもよい。 For example, in the mobile communication system according to the present embodiment, “E-UTRA Band Combination” and “Supported CC Bandwidth Combinations” may be defined as shown in FIG.
　図３に示すように、本実施形態に係る移動通信システムにおいて、１つの「Ｅ-ＵＴＲＡ　Ｂａｎｄ　Ｃｏｍｂｉｎａｔｉｏｎ」に対して、複数の「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」を規定することができる。 As shown in FIG. 3, in the mobile communication system according to this embodiment, a plurality of “Supported CC Bandwidth Combinations” can be defined for one “E-UTRA Band Combination”.
　ここで、管理部１１は、移動局ＵＥが対応する「Ｅ-ＵＴＲＡ　Ｂａｎｄ　Ｃｏｍｂｉｎａｔｉｏｎ」として、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」及び「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」の組み合わせ（図３に示す「５，１」）について管理するように構成されていてもよい。 Here, the management unit 11 has a combination of “E-UTRA Band # 5” and “E-UTRA Band # 1” as “E-UTRA Band Combination” supported by the mobile station UE (“5, shown in FIG. 3). 1 ") may be managed.
　また、管理部１１は、下りリンクにおいて移動局ＵＥが対応する「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」として、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」内の「１０ＭＨｚ」及び「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内の「１０ＭＨｚ」の組み合わせ（図３に示す「ＤＬ：１０＋１０」）について管理するように構成されていてもよい。 In addition, the management unit 11 sets “Supported CC Bandwidth Combinations” supported by the mobile station UE in the downlink as “10 MHz” in “E-UTRA Band # 5” and “10 MHz in“ E-UTRA Band # 1 ”. ”(“ DL: 10 + 10 ”shown in FIG. 3) may be managed.
　また、管理部１１は、上りリンクにおいて移動局ＵＥが対応する「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」として、下りリンクと同様の組み合わせを管理するように構成されていてもよい。 Also, the management unit 11 may be configured to manage the same combination as the downlink as “Supported CC Bandwidth Combinations” that the mobile station UE supports in the uplink.
　送信部１２は、移動局ＵＥが通信中の無線基地局ｅＮＢに対して、各種信号を送信するように構成されている。 The transmission unit 12 is configured to transmit various signals to the radio base station eNB with which the mobile station UE is communicating.
　例えば、移動局ＵＥが、本実施形態に係る移動通信システムにおいて規定されている「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」の少なくとも１つに対応している場合には、送信部１２は、無線基地局ｅＮＢに対して、移動局ＵＥが対応している「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」ではなく、移動局ＵＥにおいて所定期間内に処理可能な最大データ量を通知するように構成されている。 For example, when the mobile station UE supports at least one of “Supported CC Bandwidth Combinations” defined in the mobile communication system according to the present embodiment, the transmission unit 12 Thus, instead of “Supported CC Bandwidth Combinations” supported by the mobile station UE, the mobile station UE is configured to notify the maximum amount of data that can be processed within a predetermined period.
　ここで、かかる所定期間は、所定数（例えば、１つ）のサブフレームであってもよいし、所定数の（例えば、１つ）のＴＴＩ（Ｔｒａｎｓｍｉｓｓｉｏｎ　Ｔｉｍｅ　Ｉｎｔｅｒｖａｌ）であってもよい。 Here, the predetermined period may be a predetermined number (for example, one) subframes or a predetermined number (for example, one) TTI (Transmission Time Interval).
　また、送信部１２は、上述の最大データ量として、リソースブロック数を通知するように構成されていてもよい。 Also, the transmission unit 12 may be configured to notify the number of resource blocks as the above-described maximum data amount.
　例えば、送信部１２は、かかる最大データ量について、「ＵＥ　Ｃａｐａｂｉｌｉｔｙ（能力情報）」内の所定ビットによって通知するように構成されていてもよい。 For example, the transmission unit 12 may be configured to notify the maximum data amount by a predetermined bit in “UE Capability (capability information)”.
　受信部１３は、移動局ＵＥが通信中の無線基地局ｅＮＢから、各種信号を受信するように構成されている。 The receiving unit 13 is configured to receive various signals from the radio base station eNB with which the mobile station UE is communicating.
　例えば、受信部１３は、かかる無線基地局ｅＮＢから、スケジューリング情報を含む制御情報や、報知情報や、下りデータ等を受信するように構成されている。 For example, the receiving unit 13 is configured to receive control information including scheduling information, broadcast information, downlink data, and the like from the radio base station eNB.
　ここで、受信部１２は、本実施形態に係る移動通信システムにおいて規定されている「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」の少なくとも１つに対応している場合には、ＣＡに用いられ得る「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」及び「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内のＣＣの全帯域幅において、ＰＤＣＣＨを介して送信される制御情報を受信するように構成されていてもよい。 Here, if the receiving unit 12 corresponds to at least one of “Supported CC Bandwidth Combinations” defined in the mobile communication system according to the present embodiment, “E-UTRA Band” that can be used for CA is used. Control information transmitted via the PDCCH may be received in the entire bandwidth of the CC in “# 5” and “E-UTRA Band # 1”.
　例えば、図４（ａ）に示すように、移動局ＵＥが、下りリンクにおいて、「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」として、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」内の「１０ＭＨｚ」及び「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内の「１０ＭＨｚ」の組み合わせに対応している場合であっても、本実施形態に係る移動通信システムにおいて、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」内において「１０ＭＨｚ」の帯域幅のＣＣが用いられ、かつ、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内において「２０ＭＨｚ」の帯域幅のＣＣが用いられている場合には、図４（ｂ）に示すように、受信部１３は、ＰＤＣＣＨを介して送信される制御情報については、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内のＣＣの「２０ＭＨｚ」の全帯域幅において受信するように構成されていてもよい。 For example, as illustrated in FIG. 4A, the mobile station UE transmits “Supported CC Bandwidth Combinations” as “Supported CC Bandwidth Combinations” as “10 MHz” and “E-UTRA Band # 1” in “E-UTRA Band # 5”. In the mobile communication system according to the present embodiment, a CC having a bandwidth of “10 MHz” is used in “E-UTRA Band # 5” even when the combination of “10 MHz” is supported. In addition, when a CC having a bandwidth of “20 MHz” is used in “E-UTRA Band # 1”, the receiving unit 13 transmits the data via the PDCCH as shown in FIG. For the control information to be used, in the full bandwidth of “20 MHz” of CC in “E-UTRA Band # 1” It may be configured to trust.
　ここで、ＰＤＣＣＨを介して送信される制御情報は、各ＣＣの全帯域幅に割り当てられているが、一般的に、伝送速度は低いため、受信部１３が、ＣＡで用いられ得る「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」及び「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内のＣＣの全帯域幅において、ＰＤＣＣＨを介して送信される制御情報を受信したとしても、処理負荷が劇的に増加するということはない。 Here, although the control information transmitted via the PDCCH is allocated to the entire bandwidth of each CC, since the transmission rate is generally low, the receiving unit 13 can use “E− Even if control information transmitted via PDCCH is received in the entire bandwidth of CC in “UTRA Band # 5” and “E-UTRA Band # 1”, the processing load does not increase dramatically. .
　また、受信部１３は、ＰＣＣ及びＳＣＣにおけるＰＤＳＣＨを介して通信を行う際に、ＰＣＣで送信される下りデータサイズ及びＳＣＣで送信される下りデータサイズの合計を、該当移動局ＵＥにおいて受信可能な最大データサイズとして、ＰＤＳＣＨを介して下りデータを受信するように構成されていてもよい。 Further, when performing communication via the PDSCH in the PCC and the SCC, the receiving unit 13 can receive the total of the downlink data size transmitted in the PCC and the downlink data size transmitted in the SCC at the corresponding mobile station UE. The maximum data size may be configured to receive downlink data via the PDSCH.
　例えば、本実施形態に係る移動通信システムにおいて、移動局ＵＥに対する「ＰＣＣ」として「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」内のＣＣが設定されており、「ＳＣＣ」として「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内のＣＣが設定されている場合について考える。 For example, in the mobile communication system according to the present embodiment, CC in “E-UTRA Band # 5” is set as “PCC” for the mobile station UE, and “E-UTRA Band # 1” is set as “SCC”. Let us consider a case in which the CC is set.
　また、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」内において「１０ＭＨｚ」の帯域幅のＣＣが用いられており、かつ、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内において「２０ＭＨｚ」の帯域幅のＣＣが用いられている場合について想定する。 Also, a CC with a bandwidth of “10 MHz” is used in “E-UTRA Band # 5”, and a CC with a bandwidth of “20 MHz” is used in “E-UTRA Band # 1”. Assuming that
　かかる場合、「２０ＭＨｚ」の帯域幅まで対応可能な移動局ＵＥの受信部１３は、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内のＣＣ（ＳＣＣ）上でＰＤＳＣＨを介して下りデータを受信可能である。 In such a case, the receiving unit 13 of the mobile station UE that can handle a bandwidth of “20 MHz” can receive downlink data via the PDSCH on the CC (SCC) in the “E-UTRA Band # 1”.
　かかる移動局ＵＥは、合計２０ＭＨｚ幅までを受信可能であるため、仮に「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」において「５ＭＨｚ」のＰＤＳＣＨリソースが割り当てられていた場合、かかる移動局ＵＥは「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内のＣＣ（ＳＣＣ）上で、ＰＤＳＣＨを介して「１５ＭＨｚ」の帯域幅の下りデータを受信するように構成されている。 Since such a mobile station UE can receive a total of up to 20 MHz, if a “5 MHz” PDSCH resource is allocated in “E-UTRA Band # 5”, the mobile station UE will be able to receive “E-UTRA Band”. On the CC (SCC) in “# 1”, downlink data having a bandwidth of “15 MHz” is received via the PDSCH.
　さらに、受信部１３は、本実施形態に係る移動通信システムにおいて規定されている「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」の少なくとも１つに対応している場合には、「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃５」及び「Ｅ-ＵＴＲＡ　Ｂａｎｄ＃１」内のＣＣの中心帯域幅（例えば、中心の２８リソースブロック）に割り当てられている報知情報を受信するように構成されていてもよい。 Further, when the reception unit 13 supports at least one of “Supported CC Bandwidth Combinations” defined in the mobile communication system according to the present embodiment, “E-UTRA Band # 5” and “E -You may be comprised so that the alerting | reporting information allocated to the center bandwidth (for example, center 28 resource block) of CC in "UTRA Band # 1" may be received.
　かかる報知情報は、「Ｄｉｓｔｒｉｂｕｔｅｄ」割り当て方式によって割り当てられていてもよいし、「Ｌｏｃａｌｉｚｅｄ」割り当て方式によって割り当てられていてもよい。 The broadcast information may be assigned by the “Distributed” assignment method or may be assigned by the “Localized” assignment method.
　また、受信部１３は、本実施形態に係る移動通信システムにおいて規定されている「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」の少なくとも１つに対応している場合には、無線基地局ｅＮＢからの個別シグナリングを介して、Ｐｃｅｌｌ（ＰＣＣのサービングセル）及びＳｃｅｌｌ（ＳＣＣのサービングセル）における報知情報（ＭＩＢ（Ｍａｓｔｅｒ　Ｉｎｆｏｒｍａｔｉｏｎ　Ｂｌｏｃｋ）やＳＩＢ（Ｓｙｓｔｅｍ　Ｉｎｆｏｒｍａｔｉｏｎ　Ｂｌｏｃｋ）等）を受信するように構成されていてもよい。 In addition, the receiving unit 13 is compatible with at least one of “Supported CC Bandwidth Combinations” defined in the mobile communication system according to the present embodiment, via individual signaling from the radio base station eNB. , Pcell (PCC serving cell) and Scell (SCC serving cell) broadcast information (MIB (Master Information Block), SIB (System Information Block), etc.) may be received.
　或いは、受信部１３は、本実施形態に係る移動通信システムにおいて規定されている「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」の少なくとも１つに対応している場合には、「Ｉｎｔｅｒ-ｃｅｌｌ　Ｈａｎｄｏｖｅｒ」の際に、Ｐｃｅｌｌ及びＳｃｅｌｌにおける報知情報を受信するように構成されていてもよい。 Alternatively, if the receiving unit 13 corresponds to at least one of “Supported CC Bandwidth Combinations” defined in the mobile communication system according to the present embodiment, the receiving unit 13 performs Pcell during “Inter-cell Handover”. And broadcast information in Scell may be received.
　また、受信部１３は、本実施形態に係る移動通信システムにおいて規定されている「Ｓｕｐｐｏｒｔｅｄ　ＣＣ　Ｂａｎｄｗｉｄｔｈ　Ｃｏｍｂｉｎａｔｉｏｎｓ」の少なくとも１つに対応している場合には、移動局ＵＥに対して設定されているＣＡを一度終了した後に、Ｐｃｅｌｌ及びＳｃｅｌｌにおける報知情報を受信し、その後、かかるＣＡを再開するように構成されていてもよい。 In addition, the reception unit 13 is a CA that is set for the mobile station UE when it corresponds to at least one of “Supported CC Bandwidth Combinations” defined in the mobile communication system according to the present embodiment.
