Description

端末装置、基地局装置、方法、および、集積回路Terminal equipment, base station equipment, methods, and integrated circuits
　本発明は、端末装置、基地局装置、方法、および、集積回路に関する。
　本願は、２０１９年９月３０日に日本に出願された特願２０１９－１７９８９０号について優先権を主張し、その内容をここに援用する。 The present invention relates to terminal devices, base station devices, methods, and integrated circuits.
The present application claims priority with respect to Japanese Patent Application No. 2019-179890 filed in Japan on September 30, 2019, the contents of which are incorporated herein by reference.
　セルラ－移動通信の無線アクセス方式および無線ネットワーク（以下、「Ｌｏｎｇ　Ｔｅｒｍ　Ｅｖｏｌｕｔｉｏｎ（ＬＴＥ：登録商標）」、または、「Ｅｖｏｌｖｅｄ　Ｕｎｉｖｅｒｓａｌ　Ｔｅｒｒｅｓｔｒｉａｌ　Ｒａｄｉｏ　Ａｃｃｅｓｓ：ＥＵＴＲＡ」と称する。）、およびコアネットワーク（以下、「Ｅｖｏｌｖｅｄ　Ｐａｃｋｅｔ　Ｃｏｒｅ：ＥＰＣ」）が、第三世代パートナーシッププロジェクト（３ｒｄ　Ｇｅｎｅｒａｔｉｏｎ　Ｐａｒｔｎｅｒｓｈｉｐ　Ｐｒｏｊｅｃｔ：３ＧＰＰ）において検討されている。 Wireless access system and wireless network for cellular mobile communication (hereinafter referred to as "Long Term Evolution (LTE: registered trademark)" or "Evolved Universal Terrestrial Radio Access: EUTRA"), and core network (hereinafter referred to as "Evolved"). "Packet Core: EPC") is being considered in the 3rd Generation Partnership Project (3GPP).
　また、３ＧＰＰにおいて、第５世代のセルラ－システムに向けた無線アクセス方式および無線ネットワーク技術として、ＬＴＥの拡張技術であるＬＴＥ－Ａｄｖａｎｃｅｄ　Ｐｒｏおよび新しい無線アクセス技術であるＮＲ（Ｎｅｗ　Ｒａｄｉｏ　ｔｅｃｈｎｏｌｏｇｙ）の技術検討および規格策定が行われている（非特許文献１）。また第５世代セルラーシステムに向けたコアネットワークである、５ＧＣ（５　Ｇｅｎｅｒａｔｉｏｎ　Ｃｏｒｅ　Ｎｅｔｗｏｒｋ）の検討も行われている（非特許文献２）。 In addition, in 3GPP, as a wireless access method and wireless network technology for the 5th generation cellular system, technical studies of LTE-Advanced Pro, which is an extended technology of LTE, and NR (New Radio technology), which is a new wireless access technology. And standards have been established (Non-Patent Document 1). In addition, 5GC (5 Generation Core Network), which is a core network for the 5th generation cellular system, is also being studied (Non-Patent Document 2).
　ＬＴＥの技術の一つとして、周波数間（Ｉｎｔｅｒ－Ｆｒｅｑｕｅｎｃｙ）および／または無線アクセス技術間（Ｉｎｔｅｒ－ＲＡＴ、ＲＡＴ間）の測定のためにギャップが必要であるか否かを示す端末能力（ＵＥ　Ｃａｐａｂｉｌｉｔｙ）情報をバンドごとに基地局装置に通知する仕組みが導入されているが、Ｉｎｔｅｒ－ＲＡＴのＮＲについては常にギャップが必要であるとみなし、上記通知する仕組みが導入されていなかった。そこでＮＲを考慮した仕組み導入する検討が進められている（非特許文献１６）。 As one of the LTE technologies, a terminal capability (UE Capacity) indicating whether or not a gap is necessary for measurement between frequencies (Inter-Freequency) and / or between wireless access technologies (Inter-RAT, RAT). ) A mechanism for notifying the base station device of information for each band has been introduced, but it is always considered that a gap is necessary for the NR of Inter-RAT, and the above-mentioned notification mechanism has not been introduced. Therefore, studies are underway to introduce a mechanism that takes NR into consideration (Non-Patent Document 16).
　しかしながら、上記非特許文献１６による検討では、ＮＲのバンド情報が格納されている既存の情報要素を用いてギャップの要否を通知する仕組みを提案しているが、端末装置が既存のギャップ要否の通知を行っているのかＮＲを考慮したギャップ要否の通知を行っているのかをネットワークが識別する仕組みが提示されていないという課題があった。また、ＮＲにおけるギャップ要否の通知、およびＭＲ－ＤＣ（Ｍｕｌｔｉ－Ｒａｄｉｏ　Ｄｕａｌ　Ｃｏｎｎｅｃｔｉｖｉｔｙ）におけるギャップ要否の通知については未だ仕様化されていない。 However, in the examination according to Non-Patent Document 16 above, although a mechanism for notifying the necessity of a gap by using an existing information element in which NR band information is stored is proposed, the terminal device needs an existing gap. There is a problem that a mechanism for the network to identify whether the notification is given or the notification of the necessity of the gap in consideration of the NR is not presented. Further, the notification of the necessity of a gap in NR and the notification of the necessity of a gap in MR-DC (Multi-Radio Dual Connectivity) have not yet been specified.

　ＵＥ１２２はＥ－ＵＴＲＡ１００に対応、ＮＲ１０６に対応、またはＥ－ＵＴＲＡ１００およびＮＲ１０６の両方に対応した端末装置である。非特許文献３、および／または（ａｎｄ／ｏｒ）非特許文献９に記載の通り、ＵＥ１２２が、Ｅ－ＵＴＲＡ１００、および／またはＮＲ１０６を介してコア網と接続する際、ＵＥ１２２と、Ｅ－ＵＴＲＡ１００、および／またはＮＲ１０６との間に、無線ベアラ（ＲＢ：Ｒａｄｉｏ　Ｂｅａｒｅｒ）と呼ばれる論理経路が確立される。ＣＰに用いられる無線ベアラは、シグナリング無線ベアラ（ＳＲＢ：Ｓｉｇｎａｌｉｎｇ　Ｒａｄｉｏ　Ｂｅａｒｅｒ）と呼ばれ、ＵＰに用いられる無線ベアラは、データ無線ベアラ（ＤＲＢ　Ｄａｔａ　Ｒａｄｉｏ　Ｂｅａｒｅｒ）と呼ばれる。各ＲＢは、ＲＢ識別子（ＲＢ　Ｉｄｅｎｔｉｔｙ，またはＲＢ　ＩＤ）が割り当てられ、一意に識別される。ＳＲＢ用ＲＢ識別子は、ＳＲＢ識別子（ＳＲＢ　Ｉｄｅｎｔｉｔｙ，またはＳＲＢ　ＩＤ）と呼ばれ、ＤＲＢ用ＲＢ識別子は、ＤＲＢ識別子（ＤＲＢ　Ｉｄｅｎｔｉｔｙ，またはＤＲＢ　ＩＤ）と呼ばれる。 UE 122 is a terminal device compatible with E-UTRA100, NR106, or both E-UTRA100 and NR106. As described in Non-Patent Document 3 and / or (and / or) Non-Patent Document 9, when the UE 122 connects to the core network via the E-UTRA100 and / or the NR106, the UE 122 and the E-UTRA100, A logical path called a radio bearer (RB: Radio Bearer) is established between and / or NR106. The radio bearer used for CP is called a signaling radio bearer (SRB: Signaling Radio Bearer), and the radio bearer used for UP is called a data radio bearer (DRB Data Radio Bearer). Each RB is assigned an RB identifier (RB Identity or RB ID) and is uniquely identified. The SRB RB identifier is called an SRB identifier (SRB Identity or SRB ID), and the DRB RB identifier is called a DRB identifier (DRB Identity or DRB ID).
　非特許文献３に記載の通り、ＵＥ１２２の接続先コア網がＥＰＣ１０４である場合、ＵＥ１２２と、Ｅ－ＵＴＲＡ１００、および／またはＮＲ１０６との間に確立された各ＤＲＢは更に、ＥＰＣ１０４内を経由する各ＥＰＳ（Ｅｖｏｌｖｅｄ　Ｐａｃｋｅｔ　Ｓｙｓｔｅｍ）ベアラと一意に紐づけられる。各ＥＰＳベアラは、ＥＰＳベアラ識別子（Ｉｄｅｎｔｉｔｙ，またはＩＤ）が割り当てられ、一意に識別される。また同一のＥＰＳベアラを通るデータは同一のＱｏＳが保証される。 As described in Non-Patent Document 3, when the core network to which the UE 122 is connected is the EPC 104, each DRB established between the UE 122 and the E-UTRA 100 and / or the NR 106 further passes through the EPC 104. It is uniquely linked to the EPS (Evolved Packet System) bearer. Each EPS bearer is assigned an EPS bearer identifier (Identity, or ID) and is uniquely identified. Also, the same QoS is guaranteed for the data passing through the same EPS bearer.
　非特許文献９に記載の通り、ＵＥ１２２の接続先コア網が５ＧＣ１１０である場合、ＵＥ１２２と、Ｅ－ＵＴＲＡ１００、および／またはＮＲ１０６との間に確立された一つまたは複数のＤＲＢは更に、５ＧＣ１１０内に確立されるＰＤＵ（Ｐａｃｋｅｔ　Ｄａｔａ　Ｕｎｉｔ）セッションの一つに紐づけられる。各ＰＤＵセッションには、一つまたは複数のＱｏＳフローが存在する。各ＤＲＢは、紐づけられているＰＤＵセッション内に存在する、一つまたは複数のＱｏＳフローと対応付け（ｍａｐ）されてもよいし、どのＱｏＳフローと対応づけられなくてもよい。各ＰＤＵセッションは、ＰＤＵセッション識別子（Ｉｄｅｎｔｉｔｙ，またはＩＤ）で識別される。また各ＱｏＳフローは、ＱｏＳフロー識別子で識別される。また同一のＱｏＳフローを通るデータは同一のＱｏＳが保証される。 As described in Non-Patent Document 9, when the core network to which the UE 122 is connected is 5GC110, one or more DRBs established between the UE 122 and the E-UTRA100 and / or NR106 are further within the 5GC110. It is linked to one of the PDU (Packet Data Unit) sessions established in. There is one or more QoS flows in each PDU session. Each DRB may be associated (mapped) with one or more QoS flows existing in the associated PDU session, or may not be associated with any QoS flow. Each PDU session is identified by a PDU session identifier (Identity, or ID). Each QoS flow is identified by a QoS flow identifier. Further, the same QoS is guaranteed for the data passing through the same QoS flow.
　ＥＰＣ１０４には、ＰＤＵセッション、および／またはＱｏＳフローは存在せず、５ＧＣ１１０にはＥＰＳベアラは存在しない。言い換えると、ＵＥ１２２がＥＰＣ１０４と接続している際、ＵＥ１２２はＥＰＳベアラの情報を持ち、ＵＥ１２２が５ＧＣ１１０と接続している際、ＵＥ１２２はＰＤＵセッション、および／またはＱｏＳフローの情報を持つ。 There is no PDU session and / or QoS flow in EPC104 and no EPS bearer in 5GC110. In other words, when the UE 122 is connected to the EPC 104, the UE 122 has information on the EPS bearer, and when the UE 122 is connected to the 5GC110, the UE 122 has information on the PDU session and / or the QoS flow.

The PHY200 is connected to a higher-level MAC (Medium Access Control layer) 202, which will be described later, by a transport channel (Transport Channel). Data moves between MAC202 and PHY200 via the transport channel. Data is transmitted and received between the UE 122 and the PHY of the eNB 102 via the radio physical channel.
　ＭＡＣ２０２は、多様な論理チャネル（Ｌｏｇｉｃａｌ　Ｃｈａｎｎｅｌ）を多様なトランスポートチャネルにマッピングを行う媒体アクセス制御層（媒体アクセス制御レイヤ）である。ＭＡＣ２０２は、後述する上位のＲＬＣ（Ｒａｄｉｏ　Ｌｉｎｋ　Ｃｏｎｔｒｏｌ　ｌａｙｅｒ）２０４と、論理チャネルで接続される。論理チャネルは、伝送される情報の種類によって大きく分けられ、制御情報を伝送する制御チャネルとユ－ザ情報を伝送するトラフィックチャネルに分けられる。ＭＡＣ２０２は、間欠受送信（ＤＲＸ・ＤＴＸ）を行うためにＰＨＹ２００の制御を行う機能、ランダムアクセス（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ）手順を実行する機能、送信電力の情報を通知する機能、ＨＡＲＱ制御を行う機能などを持つ（非特許文献７）。 MAC202 is a medium access control layer (medium access control layer) that maps various logical channels to various transport channels. The MAC 202 is connected to a higher-level RLC (Radio Link Control layer) 204, which will be described later, via a logical channel. The logical channel is roughly classified according to the type of information to be transmitted, and is divided into a control channel for transmitting control information and a traffic channel for transmitting user information. The MAC202 has a function of controlling PHY200 for intermittent transmission (DRX / DTX), a function of executing a random access (Random Access) procedure, a function of notifying transmission power information, a function of performing HARQ control, and the like. Has (Non-Patent Document 7).
　ＲＬＣ２０４は、後述する上位のＰＤＣＰ（Ｐａｃｋｅｔ　Ｄａｔａ　Ｃｏｎｖｅｒｇｅｎｃｅ　Ｐｒｏｔｏｃｏｌ　Ｌａｙｅｒ）２０６から受信したデ－タを分割（Ｓｅｇｍｅｎｔａｔｉｏｎ）し、下位層（下位レイヤ）が適切にデ－タ送信できるようにデ－タサイズを調節する無線リンク制御層（無線リンク制御レイヤ）である。また、ＲＬＣ２００は、各デ－タが要求するＱｏＳ（Ｑｕａｌｉｔｙ　ｏｆ　Ｓｅｒｖｉｃｅ）を保証するための機能も持つ。すなわち、ＲＬＣ２０４は、デ－タの再送制御等の機能を持つ（非特許文献６）。 The RLC204 divides the data received from the upper PDCP (Packet Data Convergence Protocol Layer) 206, which will be described later, and adjusts the data size so that the lower layer (lower layer) can appropriately transmit the data. It is a wireless link control layer (wireless link control layer). The RLC 200 also has a function for guaranteeing the QoS (Quality of Service) required by each data. That is, the RLC 204 has a function such as data retransmission control (Non-Patent Document 6).
　ＰＤＣＰ２０６は、ユーザデータであるＩＰパケット（ＩＰ　Ｐａｃｋｅｔ）を無線区間で効率的に伝送するためのパケットデータ収束プロトコル層（パケットデータ収束プロトコルレイヤ）である。ＰＤＣＰ２０６は、不要な制御情報の圧縮を行うヘッダ圧縮機能を持ってもよい。また、ＰＤＣＰ２０６は、デ－タの暗号化の機能も持ってもよい（非特許文献５）。 PDCP206 is a packet data convergence protocol layer (packet data convergence protocol layer) for efficiently transmitting an IP packet (IP Packet) which is user data in a wireless section. The PDCP206 may have a header compression function that compresses unnecessary control information. The PDCP206 may also have a data encryption function (Non-Patent Document 5).

　上記のメッセージおよび情報要素をベースに、ＥＵＴＲＡでＲＡＴ間測定にＮＲを考慮したＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素の設定について説明する。 Based on the above message and information element, the setting of the BandInfoEUTRA information element in consideration of NR for the measurement between RATs in EUTRA will be described.
　ある実施の形態において、端末装置は、一つ以上の第１のバンドに対するＲＡＴ間測定に測定ギャップが必要であるか否かを示す情報を、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素に含める。第１のバンドは、ＵＥ－ＥＵＴＲＡ－Ｃａｐａｂｉｌｉｔｙ情報要素のｉｎｔｅｒＲＡＴ－Ｐａｒａｍｅｔｅｒｓフィールドの値に含まれる各ＲＡＴの各バンドであってよい。さらにある条件が成り立つ場合において、ＵＥ－ＥＵＴＲＡ－Ｃａｐａｂｉｌｉｔｙ情報要素のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールドの値に含まれるＮＲのバンドに対するＲＡＴ間測定に測定ギャップが必要であるか否かを示す情報を、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素に含めてよい。ある条件とは、（Ａ）ＮＲのバンドに対して測定ギャップが必要か否かを通知する場合、（Ｂ）ＮＲのバンドに対して測定ギャップが必要か否かを通知する能力を持つことをＵＥ－ＥＵＴＲＡ－Ｃａｐａｂｉｌｉｔｙ情報要素に含めた場合、（Ｃ）端末装置のＵＥ－ＥＵＴＲＡ－Ｃａｐａｂｉｌｉｔｙ情報要素のａｃｃｅｓｓＳｔｒａｔｕｍＲｅｌｅａｓｅフィールドが特定のリリースを示す値、または特定のリリースより新しいリリースを示す値を持つ場合、の一部または全部であってよい。 In certain embodiments, the terminal device includes information in the BandInfoEUTRA information element indicating whether or not a measurement gap is required for inter-RAT measurements for one or more first bands. The first band may be each band of each RAT included in the value of the interRAT-Parameters field of the UE-EUTRA-Capacity information element. Further, when a certain condition is satisfied, the BandInfoEUTRA information element provides information indicating whether or not a measurement gap is required for the measurement between RATs for the band of NR included in the value of the irat-Parameters NR field of the UE-EUTRA-Capacity information element. May be included in. A certain condition is that (A) it has the ability to notify the band of NR whether or not a measurement gap is necessary, and (B) it has the ability to notify whether or not a measurement gap is necessary for the band of NR. When included in the UE-EUTRA-Capacity information element, (C) if the GapStratumReleases field of the UE-EUTRA-Capacity information element of the terminal device has a value indicating a specific release or a value indicating a release newer than the specific release. May be part or all of.
　このとき、ある条件を考慮しない既存の動作と区別するために、例えば、図１７で示すように、端末装置がサポートするＮＲのバンド情報を示すための既存のフィールドであるｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールド（ｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲ－ｒ１５、および／またはｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲ－ｖ１５４０）（第１のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールド）とは異なる第２のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールド（例えばｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲ－ｒ１６）を導入してもよい。このとき、端末装置は、第１のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールドで示されるＮＲバンドに対するＮｅｅｄＦｏｒＧａｐｓフィールドをＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素に含めなくてよい。また、このとき、端末装置は、第２のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールドで示されるＮＲバンドに対するＮｅｅｄＦｏｒＧａｐｓフィールドをＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素に含めてよい。 At this time, in order to distinguish from the existing operation that does not consider a certain condition, for example, as shown in FIG. 17, the irat-Parameters NR field (irat), which is an existing field for showing the band information of the NR supported by the terminal device, is used. A second irat-ParametersNR field (eg, irat-ParametersNR-r16) that is different from the -ParametersNR-r15 and / or irat-ParametersNR-v1540) (first irat-ParametersNR field) may be introduced. At this time, the terminal device does not have to include the NeedForGaps field for the NR band indicated by the first irat-Parameters NR field in the BandInfoEUTRA information element. At this time, the terminal device may include the NeedForGaps field for the NR band indicated by the second irat-Parameters NR field in the BandInfoEUTRA information element.
　また、第２のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールドは、図１５で示す、ＵＥ－ＮＲ－Ｃａｐａｂｉｌｉｔｙ情報要素に含まれるｓｕｐｐｏｒｔｅｄＢａｎｄＬｉｓｔＮＲフィールドであってもよい。 Further, the second irat-Parameters NR field may be a supportedBandListNR field included in the UE-NR-DocumentsNR information element shown in FIG.
　また、例えば、端末装置は、測定ギャップが必要なＮＲバンドの情報を第１のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールドに含め、測定ギャップが必要か否かを明示するＮＲバンドの情報を第２のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールドに含めてもよい。これにより、ＮｅｅｄＦｏｒＧａｐｓを示すバンドの数を削減することができ、ＵＥ能力情報メッセージのメッセージサイズを小さくすることができる。また、例えば、端末装置は、測定ギャップが必要なＮＲバンドの情報を第１のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールドに含め、測定ギャップが不要なＮＲバンドの情報を第２のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールドに含めて、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素にＮＲのバンドに関するＮｅｅｄＦｏｒＧａｐｓを含めないようにしてもよい。これにより、ＮｅｅｄＦｏｒＧａｐｓを示すバンドの数を削減することができ、ＵＥ能力情報メッセージのメッセージサイズを小さくすることができる。 Further, for example, the terminal device includes the information of the NR band that requires the measurement gap in the first irat-Parameters NR field, and the information of the NR band that clearly indicates whether or not the measurement gap is necessary is included in the second irat-Parameters NR field. May be included in. As a result, the number of bands indicating NeedForGaps can be reduced, and the message size of the UE capability information message can be reduced. Further, for example, the terminal device includes the information of the NR band requiring the measurement gap in the first irat-Parameters NR field and the information of the NR band not requiring the measurement gap in the second irat-Parameters NR field. The information element may not include NeedForGap for the NR band. As a result, the number of bands indicating NeedForGaps can be reduced, and the message size of the UE capability information message can be reduced.
　また、例えば、特定のバンド（例えばＦｒｑｅｕｅｎｃｙ　Ｒａｎｇｅ　２：ＦＲ２）のバンドについては常に測定ギャップが不要であるとみなされてもよい。この場合、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素には、ＦＲ２以外のＮＲバンドに対するＮｅｅｄＦｏｒＧａｐｓフィールドが含まれてよい。また、この場合、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素には、ＦＲ２のＮＲバンドに対するＮｅｅｄＦｏｒＧａｐｓフィールドが含まれなくてもよい。例えば、第２のｉｒａｔ－ＰａｒａｍｅｔｅｒｓＮＲフィールドにはＦＲ２のＮＲバンドと、ＦＲ２以外のＮＲバンドの両方のバンドの情報が含まれる場合に、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素には、ＦＲ２のＮＲバンドに対するＮｅｅｄＦｏｒＧａｐｓフィールドが含まれなくてもよい。 Further, for example, it may be considered that the measurement gap is not always necessary for the band of a specific band (for example, Frequency Range 2: FR2). In this case, the BandInfoEUTRA information element may include a NeedForGaps field for NR bands other than FR2. Further, in this case, the BandInfoEUTRA information element may not include the NeedForGaps field for the NR band of FR2. For example, when the second irat-Parameters NR field contains information on both the NR band of FR2 and the NR band other than FR2, the BandInfoEUTRA information element contains a NeedForGaps field for the NR band of FR2. It does not have to be.
　また、端末装置は、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素に各ＮＲバンドに対する測定ギャップの要否を示す情報を含めることを示す情報をＵＥ－ＥＵＴＲＡ－Ｃａｐａｂｉｌｉｔｙ情報要素に含めてもよい。また、端末装置は、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素に含まれるＲＡＴ間測定のＮｅｅｄＦｏｒＧａｐｓフィールドの数に基づき、ＮＲバンドに対する測定ギャップの要否を示す情報を含まれているか否かを判断してもよい。 Further, the terminal device may include information indicating that the BandInfoEUTRA information element includes information indicating the necessity of the measurement gap for each NR band in the UE-EUTRA-Capacity information element. Further, the terminal device may determine whether or not the terminal device includes information indicating the necessity of the measurement gap with respect to the NR band based on the number of NeedForGaps fields of the inter-RAT measurement included in the BandInfoEUTRA information element.
　また、端末装置は、ＵＥ－ＥＵＴＲＡ－Ｃａｐａｂｉｌｉｔｙ情報要素のａｃｃｅｓｓＳｔｒａｔｕｍＲｅｌｅａｓｅフィールドが特定のリリースを示す値、または特定のリリースより新しいリリースを示す値を持つことで、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素に、ＮＲバンドに対する測定ギャップの要否を示す情報を含まれているか否かを判断してもよい。また、端末装置は、ＢａｎｄＩｎｆｏＥＵＴＲＡ情報要素に、ＮＲバンドに対する測定ギャップの要否を示すフィールドを含めてもよい。これにより、ＮＲを考慮したＲＡＴ間測定の測定ギャップの要否を通知することができる。 In addition, the terminal device has a value indicating a specific release or a value indicating a release newer than the specific release in the accessStratumReleasure field of the UE-EUTRA-Capacity information element, so that the BandInfoEUTRA information element has a measurement gap for the NR band. It may be determined whether or not the information indicating the necessity is included. In addition, the terminal device may include a field indicating the necessity of the measurement gap with respect to the NR band in the BandInfoEUTRA information element. Thereby, it is possible to notify the necessity of the measurement gap of the measurement between RATs in consideration of NR.
　上記のメッセージおよび情報要素をベースとした、ＮＲで周波数間測定および／またはＲＡＴ間測定を考慮したＢａｎｄＩｎｆｏＮＲ情報要素の導入について説明する。 The introduction of the BandInfoNR information element based on the above message and information element and considering the inter-frequency measurement and / or the inter-RAT measurement by NR will be described.
