Description

端末、無線通信方法及び基地局Terminal, wireless communication method and base station
　本開示は、次世代移動通信システムにおける端末、無線通信方法及び基地局に関する。 The present disclosure relates to terminals, wireless communication methods, and base stations in next-generation mobile communication systems.
　Universal　Mobile　Telecommunications　System（ＵＭＴＳ）ネットワークにおいて、更なる高速データレート、低遅延などを目的としてLong　Term　Evolution（ＬＴＥ）が仕様化された（非特許文献１）。また、ＬＴＥ（Third　Generation　Partnership　Project（３ＧＰＰ）　Release（Ｒｅｌ．）８、９）の更なる大容量、高度化などを目的として、ＬＴＥ－Ａｄｖａｎｃｅｄ（３ＧＰＰ　Ｒｅｌ．１０－１４）が仕様化された。 In the Universal Mobile Telecommunications System (UMTS) network, Long Term Evolution (LTE) has been specified for the purpose of further high data rate, low delay, etc. (Non-Patent Document 1). In addition, LTE-Advanced (3GPP Rel. 10-14) has been specified for the purpose of further increasing the capacity and sophistication of LTE (Third Generation Partnership Project (3GPP) Release (Rel.) 8, 9).
　ＬＴＥの後継システム（例えば、5th　generation　mobile　communication　system（５Ｇ）、５Ｇ＋（plus）、6th　generation　mobile　communication　system（６Ｇ）、New　Radio（ＮＲ）、３ＧＰＰ　Ｒｅｌ．１５以降などともいう）も検討されている。 LTE successor systems (for example, 5th generation mobile communication system (5G), 5G+ (plus), 6th generation mobile communication system (6G), New Radio (NR), 3GPP Rel. 15 and later) are also being considered. .
　将来の無線通信システム（例えば、ＮＲ）において、複数の端末（ユーザ端末（user　terminal）、User　Equipment（ＵＥ））が、超高密度かつ高トラヒックな環境下で通信を行うことが想定される。 In future wireless communication systems (for example, NR), it is assumed that multiple terminals (user terminals, user equipment (UE)) will communicate in an ultra-high-density and high-traffic environment.
　このような環境下において、下りリンク（ＤＬ）のリソースと比較し、上りリンク（ＵＬ）のリソースが不足することが想定される。 Under such an environment, it is assumed that uplink (UL) resources will be insufficient compared to downlink (DL) resources.
　しかしながら、これまでのＮＲ仕様においては、上りリンクのリソースを増大させる方法について、十分検討がなされていない。当該方法を適切に制御できなければ、遅延の増大やカバレッジ性能の低下など、システム性能が低下するおそれがある。 However, in the NR specifications so far, sufficient consideration has not been given to methods for increasing uplink resources. Failure to properly control the method may result in degraded system performance, such as increased delay and reduced coverage performance.
　そこで、本開示は、リソースの利用効率を高める端末、無線通信方法及び基地局を提供することを目的の１つとする。 Therefore, one of the objects of the present disclosure is to provide a terminal, a wireless communication method, and a base station that improve resource utilization efficiency.
　本開示の一態様に係る端末は、下りリンク（ＤＬ）リソースと上りリンク（ＵＬ）リソースとが周波数分割多重可能なリソースの設定情報と、測定用のＤＬ参照信号の時間リソースに関する情報と、を受信する受信部と、前記リソースの設定情報、前記時間リソースに関する情報、及び、前記測定用のＤＬ参照信号の測定に関する能力情報の報告、の少なくとも１つに基づいて、前記測定用のＤＬ参照信号に基づく測定を制御する制御部と、を有する。 A terminal according to an aspect of the present disclosure provides resource configuration information for which downlink (DL) resources and uplink (UL) resources can be frequency division multiplexed, and information about time resources of DL reference signals for measurement. Based on at least one of the receiving unit to receive, the resource configuration information, the information on the time resource, and a report of capability information on measurement of the DL reference signal for measurement, the DL reference signal for measurement and a control unit for controlling the measurement based on.
　本開示の一態様によれば、リソースの利用効率を高めることができる。 According to one aspect of the present disclosure, resource utilization efficiency can be improved.

　アンライセンスバンド（例えば、２．４ＧＨｚ帯、５ＧＨｚ帯、６ＧＨｚ帯など、アンライセンススペクトラム、シェアードスペクトラムと呼ばれてもよい）では、例えば、Ｗｉ－Ｆｉシステム、Licensed-Assisted　Access（ＬＡＡ）をサポートするシステム（ＬＡＡシステム）等の複数のシステムが共存することが想定されるため、当該複数のシステム間での送信の衝突回避及び／又は干渉制御が必要となると考えられる。 (unlicensed band)
In unlicensed bands (eg, 2.4 GHz band, 5 GHz band, 6 GHz band, etc., may be called unlicensed spectrum, shared spectrum), for example, Wi-Fi system, Licensed-Assisted Access (LAA) is supported Since it is assumed that a plurality of systems such as a system (LAA system) coexist, transmission collision avoidance and/or interference control among the plurality of systems is considered necessary.
　既存のＬＴＥシステム（例えば、Ｒｅｌ．１３）のＬＡＡでは、データの送信装置は、アンライセンスバンドにおけるデータの送信前に、他の装置（例えば、基地局、ユーザ端末、Ｗｉ－Ｆｉ装置など）の送信の有無を確認するリスニングを行う。当該リスニングは、Listen　Before　Talk（ＬＢＴ）、Clear　Channel　Assessment（ＣＣＡ）、キャリアセンス、チャネルのセンシング、センシング、チャネルアクセス動作（channel　access　procedure）、共有スペクトルチャネルアクセス動作（shared　spectrum　channel　access　procedure）、エネルギー検出（Energy　Detection（ＥＤ））などと呼ばれてもよい。 In LAA of the existing LTE system (eg, Rel.13), the data transmission device, before transmitting data in the unlicensed band, other devices (eg, base stations, user terminals, Wi-Fi devices, etc.) of Perform listening to check for transmission. The listening includes Listen Before Talk (LBT), Clear Channel Assessment (CCA), carrier sense, channel sensing, sensing, channel access procedure, shared spectrum channel access procedure, energy It may be called detection (Energy Detection (ED)) or the like.
　当該送信装置は、例えば、下りリンク（ＤＬ）では基地局（例えば、gNodeB（ｇＮＢ）、ネットワーク（ＮＷ）と呼ばれてもよい）、上りリンク（ＵＬ）ではユーザ端末（ＵＥ）であってもよい。また、送信装置からのデータを受信する受信装置は、例えば、ＤＬではユーザ端末、ＵＬでは基地局（ＮＷ）であってもよい。 The transmitting device may be, for example, a base station (eg, gNodeB (gNB), may also be referred to as a network (NW)) on the downlink (DL) and a user terminal (UE) on the uplink (UL). good. Also, the receiving device that receives data from the transmitting device may be, for example, a user terminal in DL and a base station (NW) in UL.
　既存のＬＴＥシステムのＬＡＡでは、当該送信装置は、ＬＢＴにおいて他の装置の送信がないこと（アイドル状態）が検出されてから所定期間（例えば、直後又はバックオフの期間）後にデータ送信を開始する。 In the LAA of the existing LTE system, the transmitting device is detected that there is no transmission of other devices in the LBT (idle state) for a predetermined period (eg, immediately after or backoff period) after starting data transmission .
　将来の無線通信システム（例えば、５Ｇ、５Ｇ＋、New　Radio（ＮＲ）、３ＧＰＰ　Ｒｅｌ．１５以降などともいう）でもアンライセンスバンドの利用が検討されている。アンライセンスバンドを用いるＮＲシステムは、ＮＲ－Unlicensed（Ｕ）システム、ＮＲ　ＬＡＡシステムなどと呼ばれてもよい。 Future wireless communication systems (for example, 5G, 5G+, New Radio (NR), 3GPP Rel. 15 and later) are also considering the use of unlicensed bands. An NR system using an unlicensed band may be called an NR-Unlicensed (U) system, an NR LAA system, or the like.
　ライセンスバンドとアンライセンスバンドとのデュアルコネクティビティ（Dual　Connectivity（ＤＣ））、アンライセンスバンドのスタンドアローン（Stand-Alone（ＳＡ））なども、ＮＲ－Ｕに含まれてもよい。 NR-U may also include dual connectivity (DC) between licensed and unlicensed bands, stand-alone (SA) for unlicensed bands, and the like.
　ＮＲ－Ｕにおけるノード（例えば、基地局、ＵＥ）は、他システム又は他オペレータとの共存のため、ＬＢＴによりチャネルが空いていること（idle）を確認してから、送信を開始する。 A node (eg, base station, UE) in NR-U starts transmission after confirming that the channel is idle by LBT for coexistence with other systems or operators.
　ＮＲ－Ｕにおいて、基地局（例えば、ｇＮＢ）又はＵＥは、ＬＢＴ結果がアイドルである場合に送信機会（Transmission　Opportunity（ＴｘＯＰ））を獲得し、送信を行う。基地局又はＵＥは、ＬＢＴ結果がビジーである場合（LBT-busy）に、送信を行わない。送信機会の時間は、チャネル占有時間（Channel　Occupancy　Time（ＣＯＴ））と呼ばれてもよい。 In NR-U, the base station (eg, gNB) or UE acquires a transmission opportunity (TxOP) and transmits when the LBT result is idle. The base station or UE does not transmit if the LBT result is busy (LBT-busy). The time of transmission opportunity may be referred to as the Channel Occupancy Time (COT).
　なお、LBT-idleは、ＬＢＴの成功（LBT　success）で読み替えられてもよい。LBT-busyは、ＬＢＴの失敗（LBT　failure）で読み替えられてもよい。 It should be noted that LBT-idle may be read as LBT success. LBT-busy may be read as LBT failure.
（ＸＤＤ）
　Ｒｅｌ．１４までのＬＴＥにおいては、周波数分割複信（Frequency　Division　Duplex（ＦＤＤ））をメインに実用化され、時分割複信（Time　Division　Duplex（ＴＤＤ））にも対応した。 (XDD)
Rel. In LTE up to 14, frequency division duplex (FDD) was mainly put into practical use, and time division duplex (TDD) was also supported.
　一方、Ｒｅｌ．１５からのＮＲにおいては、ＴＤＤがメインに検討され、同時にＦＤＤにも対応（例えば、ＬＴＥバンドのマイグレーション等）した。 On the other hand, Rel. In NR from 15, TDD was mainly considered, and at the same time, FDD was also supported (for example, LTE band migration, etc.).
　ＦＤＤにおいては、ＤＬ受信及びＵＬ送信を同時に行うことができ、遅延削減の観点で好ましい。一方で、ＦＤＤにおいては、ＤＬ及びＵＬのリソース比は固定（例えば、１対１）である。 In FDD, DL reception and UL transmission can be performed simultaneously, which is preferable from the viewpoint of delay reduction. On the other hand, in FDD, the DL and UL resource ratio is fixed (eg, 1:1).
　ＴＤＤにおいては、ＤＬ及びＵＬリソースの比率を変更することが可能であり、例えば、ＤＬのトラヒックが相対的に大きい一般的な環境において、ＤＬリソース量を増加させ、ＤＬのスループット向上を図ることが可能である。 In TDD, it is possible to change the ratio of DL and UL resources, for example, in a general environment where DL traffic is relatively large, it is possible to increase the amount of DL resources and improve DL throughput. It is possible.
　一方で、Ｒｅｌ．１６までのＴＤＤによる送受信の時間比を考慮すると、ＵＬ信号／チャネルの送信機会が、ＤＬ信号／チャネルの受信機会に対して少なくなるケースが考えられる。このようなケースだと、ＵＥは頻繁なＵＬ信号／チャネルの送信を行うことができず、重要なＵＬ信号／チャネルの送信の遅延が発生することが懸念される。また、ＤＬ受信機会と比較してＵＬ送信機会が少なくなるため、ＵＬ送信機会における信号／チャネルの混雑も懸念される。さらに、ＴＤＤではＵＬ信号／チャネルの送信を行うことができる時間リソースが限定されるため、例えば繰り返し送信（Repetition）によるＵＬカバレッジ拡張技術の適用も限定的となってしまう。 On the other hand, Rel. Considering the time ratio of transmission and reception with TDD up to 16, there may be cases where the transmission opportunities for UL signals/channels are less than the reception opportunities for DL signals/channels. In such a case, the UE may not be able to transmit UL signals/channels frequently, which may cause delays in transmission of critical UL signals/channels. Signal/channel congestion at UL transmission opportunities is also a concern, as there are fewer UL transmission opportunities compared to DL reception opportunities. Furthermore, in TDD, the time resource for transmitting UL signals/channels is limited, so the application of UL coverage extension technology by, for example, repetition transmission (Repetition) is also limited.
　将来の無線通信システム（例えば、Ｒｅｌ．１７／１８以降）において、ＵＬ及びＤＬに対してＴＤＤと周波数分割複信（Frequency　Division　Duplex（ＦＤＤ））とを組み合わせた分割複信方法が導入されることが検討されている。 In future wireless communication systems (eg, Rel.17/18 and later), a division duplex method that combines TDD and Frequency Division Duplex (FDD) for UL and DL will be introduced. is being considered.
　当該分割複信方法は、ＸＤＤ（Cross　Division　Duplex）と呼ばれてもよい。ＸＤＤは、ＴＤＤバンドの１コンポーネントキャリア（ＣＣ）内における、又は、複数のＣＣにおける、ＤＬ及びＵＬを周波数分割多重する（ＤＬ及びＵＬを同時に利用可能な）複信方法を意味してもよい。当該複信方法が複数のＣＣに適用される場合、あるＣＣでＤＬを利用可能である時間リソースにおいて、別のＣＣではＵＬを利用可能であることを意味してもよい。当該複数のＣＣは、同一バンドにおけるＣＣであってもよい。 The division duplex method may be called XDD (Cross Division Duplex). XDD may refer to a duplexing method that frequency division multiplexes the DL and UL within one component carrier (CC) of the TDD band or on multiple CCs (DL and UL can be used simultaneously). If the duplexing method is applied to multiple CCs, it may mean that UL is available on another CC in time resources where DL is available on another CC. The plurality of CCs may be CCs in the same band.
　図１Ａは、Ｒｅｌ．１６までに規定されるＴＤＤの設定の一例を示す図である。図１Ａに示す例において、ＵＥに対し、１つのコンポーネントキャリア（ＣＣ）（セル、サービングセルと呼ばれてもよい）の帯域幅で、ＴＤＤのスロット／シンボルの設定が行われる。 Fig. 1A shows the Rel. 16 is a diagram showing an example of setting of TDD defined up to 16. FIG. In the example shown in FIG. 1A, a UE is configured with TDD slots/symbols in the bandwidth of one component carrier (CC) (cell, which may also be called a serving cell).
　図１Ａに示す例では、ＤＬスロットとＵＬスロットの時間比は、４：１である。このような従来のＴＤＤにおけるスロット／シンボルの設定では、ＵＬ時間リソースを十分に確保できず、ＵＬ送信遅延の発生やカバレッジ性能低下の恐れがある。 In the example shown in FIG. 1A, the time ratio between DL slots and UL slots is 4:1. With such a conventional TDD slot/symbol setting, sufficient UL time resources cannot be secured, and there is a risk of occurrence of UL transmission delay and degradation of coverage performance.
　図１Ｂは、ＸＤＤの構成の一例を示す図である。図１Ｂの例では、１コンポーネントキャリア（ＣＣ）内で、ＤＬの受信に用いられるリソースと、ＵＬの送信に用いられるリソースと、が時間的に重複する。このようなリソースの構成によれば、ＵＬリソースを確保することができ、リソースの利用効率の向上を図ることができる。 FIG. 1B is a diagram showing an example of the configuration of XDD. In the example of FIG. 1B, resources used for DL reception and resources used for UL transmission overlap in time within one component carrier (CC). According to such a resource configuration, it is possible to secure UL resources and improve the utilization efficiency of resources.
　例えば、図１Ｂに示す例のように、１ＣＣにおける周波数領域のうち、両端をＤＬに構成し、そのＤＬでＵＬリソースを挟むような構成とすることで、近隣のキャリアとのクロスリンク干渉（Cross　Link　Interference（ＣＬＩ））の発生を回避及び緩和することができる。また、ＤＬリソースとＵＬリソースとの境界には、ガードのための領域が設定されてもよい。 For example, as in the example shown in FIG. 1B , both ends of the frequency domain in one CC are configured as DL, and by configuring the DL to sandwich the UL resource, cross-link interference with neighboring carriers (Cross It is possible to avoid and mitigate the occurrence of Link Interference (CLI). Also, a guard area may be set at the boundary between the DL resource and the UL resource.
　自己干渉の処理の複雑さを考慮すると、基地局のみがＤＬリソース及びＵＬリソースを同時に使用することが考えられる。つまり、ＤＬ及びＵＬが時間的に重複しているリソースでは、あるＵＥがＤＬリソースを使用し、別のＵＥがＵＬリソースを使用する構成としてもよい。 Considering the complexity of self-interference processing, it is conceivable that only the base station uses DL resources and UL resources at the same time. That is, in resources where DL and UL temporally overlap, a configuration may be adopted in which one UE uses DL resources and another UE uses UL resources.
　図２は、ＸＤＤの構成の一例を示す図である。図２に示す例では、ＴＤＤバンドのＤＬリソースの一部をＵＬリソースとし、ＤＬとＵＬとが一部時間的に重複する構成としている。 FIG. 2 is a diagram showing an example of the configuration of XDD. In the example shown in FIG. 2, a part of the DL resource of the TDD band is used as the UL resource, and the DL and the UL are partially overlapped in terms of time.
　図２に示す例において、ＤＬのみの期間は、複数のＵＥ（図２では、ＵＥ＃１及びＵＥ＃２）のそれぞれがＤＬチャネル／信号を受信する。 In the example shown in FIG. 2, each of the multiple UEs (UE#1 and UE#2 in FIG. 2) receives the DL channel/signal during the DL-only period.
　また、ＤＬ及びＵＬが時間的に重複する期間では、あるＵＥ（図２の例では、ＵＥ＃１）がＤＬチャネル／信号の受信を行い、別のＵＥ（図２の例では、ＵＥ＃２）がＵＬチャネル／信号の送信を行う。この期間では、基地局は、ＤＬ及びＵＬの同時送受信を行う。 Also, in the period when the DL and UL temporally overlap, a certain UE (UE # 1 in the example of FIG. 2) performs reception of the DL channel / signal, and another UE (UE # 2 in the example of FIG. 2 ) carries out the transmission of the UL channels/signals. During this period, the base station performs simultaneous DL and UL transmission and reception.
　さらに、ＵＬのみの期間は、複数のＵＥのそれぞれがＵＬチャネル／信号を送信する。 Furthermore, during UL-only periods, each of the multiple UEs transmits UL channels/signals.
　既存の（例えば、Ｒｅｌ．１５／１６までに規定される）ＮＲでは、ＵＥ用キャリアにおけるＤＬ周波数リソース及びＵＬ周波数リソースは、それぞれＤＬ帯域幅部分（Bandwidth　Part（ＢＷＰ））及びＵＬ　ＢＷＰとして設定される。ＤＬ／ＵＬの周波数リソースを別のＤＬ／ＵＬの周波数リソースに切り替えるためには、複数のＢＷＰの設定とＢＷＰのアダプテーションのメカニズムとが必要である。 In the existing NR (for example, defined by Rel.15/16), the DL frequency resource and UL frequency resource in the UE carrier are set as DL bandwidth part (BWP) and UL BWP, respectively. be. In order to switch a DL/UL frequency resource to another DL/UL frequency resource, multiple BWP configurations and a BWP adaptation mechanism are required.
　また、既存のＮＲでは、ＵＥ用ＴＤＤキャリアにおける時間リソースは、ＴＤＤ設定において、ＤＬ、ＵＬ及びフレキシブル（ＦＬ）の少なくとも１つとして設定される。 Also, in the existing NR, the time resource in the TDD carrier for UE is configured as at least one of DL, UL and flexible (FL) in TDD configuration.
　ＸＤＤ動作に対する時間ドメイン及び周波数ドメインのリソースの設定方法が、検討されている。例えば、図２のＵＥ＃１に対しては、ＸＤＤのリソース（ＤＬ及びＵＬが重複する期間）を、既存のＤＬリソースと同様に設定することで（例えば、周波数ドメインリソース割り当て（ＦＤＲＡ）を用いてＵＬリソースの部分の使用を避けた上で）、仕様／ＵＥへの影響を最小限に抑えることができる（図３Ａ参照）。 How to configure time domain and frequency domain resources for XDD operation is being considered. For example, for UE #1 in FIG. 2, by setting the XDD resource (the period in which DL and UL overlap) in the same way as the existing DL resource (for example, using frequency domain resource allocation (FDRA) (while avoiding using part of the UL resource for the UE), the impact on the specification/UE can be minimized (see Figure 3A).
　また、例えば、図２のＵＥ＃２に対しては、ＸＤＤのリソースを、既存のＵＬリソースと同様に設定することで（例えば、周波数ドメインリソース割り当て（ＦＤＲＡ）を用いてＤＬリソースの部分の使用を避けた上で）、仕様／ＵＥへの影響を最小限に抑えることができる（図３Ｂ参照）。 Further, for example, for UE #2 in FIG. 2, XDD resources are configured in the same way as existing UL resources (for example, frequency domain resource allocation (FDRA) is used to use the DL resource part (while avoiding
　ところで、上記ＸＤＤ構成において、端末が測定（メジャメント（Measurement）、メジャメント動作と呼ばれてもよい）を行うことが考えられる。 By the way, in the above XDD configuration, it is conceivable that the terminal performs measurement (which may also be referred to as measurement or measurement operation).
　しかしながら、ＸＤＤ構成においてメジャメント動作を行う場合、リソースの管理に問題が生じる恐れがある。例えば、ＤＬ参照信号（例えば、同期信号ブロック（ＳＳＢ）及チャネル状態情報参照信号（ＣＳＩ－ＲＳ）の少なくとも一方など）が送信されるリソース、及び、受信信号強度（例えば、Received　Signal　Strength　Indicator（ＲＳＳＩ））の測定が行われるリソース、の少なくとも１つがＸＤＤ構成におけるリソース（特に、ＵＬリソース）に設定／指示される場合、ＵＥは、メジャメント動作及びＵＬ送信の動作を同時に行うことができない。 However, when performing measurement operations in the XDD configuration, there is a risk of resource management problems. For example, a resource on which a DL reference signal (eg, at least one of a synchronization signal block (SSB) and a channel state information reference signal (CSI-RS)) is transmitted, and a received signal strength (eg, a Received Signal Strength Indicator (RSSI )) resource on which the measurement is performed, at least one of is set / indicated to the resource in the XDD configuration (in particular, the UL resource), the UE can not perform the measurement operation and the UL transmission operation at the same time.
　既存の仕様（Ｒｅｌ．１６まで）においても、ＵＥがメジャメントを行うシンボル上では、ＵＬ送信が行われないことが規定されている。 Even in existing specifications (up to Rel. 16), it is stipulated that UL transmission is not performed on symbols on which the UE measures.
　一方、ＤＬ参照信号が送信されるリソース、及び、受信信号強度の測定が行われるリソース、の少なくとも１つがＸＤＤ構成におけるＤＬリソースに設定／指示される場合、ＵＥは、当該ＤＬリソースにおいてメジャメントを行うことができる。 On the other hand, if at least one of the resources in which the DL reference signal is transmitted and the resources in which the received signal strength is measured is set/instructed to the DL resources in the XDD configuration, the UE performs measurements in the DL resources. be able to.
　しかしながら、この場合、ＸＤＤ構成におけるＤＬリソースにおける測定は、近傍のＵＥからのＵＬ送信／電力から影響を受けることが懸念される。 However, in this case there is concern that measurements on DL resources in XDD configuration will be affected by UL transmission/power from nearby UEs.
　図４は、ＸＤＤリソースにおけるメジャメントの一例を示す図である。図４に示す例では、図２に示したような複数のＵＥ（ＵＥ＃１及びＵＥ＃２）に対するＸＤＤリソースが設定される。図２に示したように、図４のＸＤＤリソースにおいてＵＥ＃１はＤＬ受信を行い、ＵＥ＃２はＵＬ送信を行う。 FIG. 4 is a diagram showing an example of measurements in XDD resources. In the example shown in FIG. 4, XDD resources are configured for multiple UEs (UE#1 and UE#2) as shown in FIG. As shown in FIG. 2, UE#1 performs DL reception and UE#2 performs UL transmission in the XDD resource of FIG.
　図４に示す例では、ＵＥ＃１及びＵＥ＃２のそれぞれがメジャメントを行う時間リソースが異なる。このようなケースにおいて、どのようにメジャメント動作を実現するかについて検討が十分でない。 In the example shown in FIG. 4, UE#1 and UE#2 use different time resources for making measurements. In such a case, sufficient consideration has not been given as to how to implement the measurement operation.
　また、将来の無線通信システム（例えば、Ｒｅｌ．１８／１９以降）において、ＵＥにおいて、同じ時間リソースにおけるＤＬ受信及びＵＬ送信を行うこと（サポートされること）も検討されている。 Also, in future wireless communication systems (for example, Rel.18/19 and later), UEs are considering performing (supporting) DL reception and UL transmission in the same time resource.
　本開示において、同じ時間リソースにおけるＤＬ受信及びＵＬ送信、ＤＬ受信リソース及びＵＬ送信リソースが周波数分割多重（ＦＤＭ）される送受信、同時送受信動作、同時送受信、全二重（Full　Duplex（ＦＤ））通信、サブバンド非重複全二重（Subband　non-overlapping　full　duplex）、サブバンド非重複全二重通信、ＸＤＤ、ＸＤＤ通信、ＸＤＤ動作、時間周波数分割多重、時間周波数分割多重通信、時間周波数分割多重動作、は互いに読み替えられてもよい。 In the present disclosure, DL reception and UL transmission in the same time resource, transmission and reception in which DL reception resource and UL transmission resource are frequency division multiplexed (FDM), simultaneous transmission and reception operation, simultaneous transmission and reception, full duplex (FD) communication , subband non-overlapping full duplex, subband non-overlapping full duplex communication, XDD, XDD communication, XDD operation, time frequency division multiplexing, time frequency division multiplexing communication, time frequency division multiplexing operation , may be read interchangeably.
　サブバンド非重複全二重通信は、上述のＸＤＤリソースにおいて行われてもよい。 Sub-band non-overlapping full-duplex communication may be performed on the XDD resources described above.
　サブバンド非重複全二重通信におけるＤＬリソースでは、ＵＥは、任意のセルからのデータ／制御情報の受信と、周辺セルを含む複数のセルを対象とするメジャメント動作と、の少なくとも１つを行うことが考えられる。 In the DL resource in subband non-overlapping full-duplex communication, the UE performs at least one of reception of data / control information from any cell and measurement operation targeting a plurality of cells including neighboring cells. can be considered.
　サブバンド非重複全二重通信におけるＵＬリソースでは、ＵＥは、任意のセルへのデータ／制御情報の送信と、（例えば、メジャメントのための）ＵＬ参照信号及び（例えば、ランダムアクセスのための）ＰＲＡＣＨの送信と、の少なくとも１つを行うことが考えられる。 For UL resources in sub-band non-overlapping full-duplex communication, the UE can transmit data/control information to any cell, and UL reference signals (eg, for measurements) and It is conceivable to perform at least one of transmission of PRACH and
　このようなサブバンド非重複全二重通信において、ＵＥが同時送受信できる信号／チャネルに関する検討が十分でない。 In such subband non-overlapping full-duplex communication, there is not enough consideration of signals/channels that UEs can simultaneously transmit and receive.
　例えば、メジャメントのためのＤＬ受信動作及びＵＬ送信動作を同時に行うことができるか否かと、サービングセルとのデータの同時送受信を行うことができるか否かとについて、ＵＥに要求される機能が共通か異なるかについて検討が十分でない。また、データとは異なるビームを利用する、メジャメントのためのＵＬ参照信号／ランダムアクセスチャネルのの送信及びＤＬ受信動作を同時に行うことができるか否かと、サービングセルとのデータの同時送受信を行うことができるか否かとについて、ＵＥに要求される機能が共通か異なるかについて検討が十分でない。 For example, whether the DL reception operation and UL transmission operation for measurement can be performed at the same time, and whether it is possible to perform simultaneous transmission and reception of data with the serving cell, the functions required of the UE are common or different. Insufficient consideration of whether In addition, whether or not it is possible to simultaneously perform transmission and DL reception operations of the UL reference signal/random access channel for measurement, which uses a beam different from the data, and simultaneous transmission and reception of data with the serving cell can be performed. Regarding whether or not it is possible, there is not sufficient consideration of whether the functions required of the UE are the same or different.
　また、ＸＤＤ構成が利用されるバンド（ＴＤＤバンド）には、アンライセンスバンド（アンライセンスドバンド、アンライセンスＴＤＤバンド、ＮＲ－Unlicensed（Ｕ）システム、又は、シェアードスペクトラムと呼ばれてもよい）の周波数帯が含まれることが検討されている。 In addition, the band (TDD band) in which the XDD configuration is used includes the unlicensed band (unlicensed band, unlicensed TDD band, NR-Unlicensed (U) system, or shared spectrum) frequency. The inclusion of obi is being considered.
　しかしながら、アンライセンスバンドの周波数においてＸＤＤを利用する方法について検討が十分でない。 However, there is not enough research on how to use XDD in unlicensed band frequencies.
　例えば、アンライセンスバンドの周波数においてＸＤＤを利用する際に、基地局のＤＬ送信中に、ＵＥが一部の帯域（周波数リソース）においてＵＬ送信を開始する場合に以下のような問題が発生する恐れがある：
　・ＬＢＴを行わずに当該ＵＬ送信を開始する場合、干渉が発生する。
　・ＤＬチャネル／信号の受信電力が、ＸＤＤのリソースを含むＬＢＴを行う帯域に影響を与え、ＵＬ送信のためのＬＢＴが失敗する。
　・上記干渉／ＬＢＴの失敗を避けるためにガード期間（時間リソース）／ガードサブキャリア（周波数リソース）を設定することは、リソース利用の効率化を抑制する。 For example, when using XDD in the frequency of the unlicensed band, during the DL transmission of the base station, the following problems may occur if the UE starts UL transmission in some bands (frequency resources) There is:
- If the UL transmission is started without LBT, interference will occur.
• The received power of the DL channel/signal impacts the LBT band including XDD resources, and the LBT for UL transmission fails.
- Setting the guard period (time resource) / guard subcarrier (frequency resource) to avoid the above interference / LBT failure suppresses the efficiency of resource utilization.
　これらの検討が十分でない場合、リソース利用効率を適切に向上させることができず、システム性能が低下するおそれがある。 If these considerations are not sufficient, resource utilization efficiency may not be improved appropriately, and system performance may decline.
　そこで本発明者らは、上記問題を解決する方法を着想した。 Therefore, the inventors came up with a method to solve the above problem.

＜第１の実施形態＞
　第１の実施形態では、ＸＤＤリソースにおけるメジャメント動作について説明する。 <First embodiment>
In the first embodiment, a measurement operation in XDD resources will be described.
　ＵＥは、ＤＬ参照信号（例えば、測定用のＤＬ参照信号）に関連する特定の時間リソースにおいて、ＸＤＤリソースが設定されないと想定（assume）／期待（expect）してもよい。また、ＵＥは、ＤＬ参照信号（例えば、測定用のＤＬ参照信号）に関連する特定の時間リソースにおいて、ＸＤＤリソースが設定されると想定（assume）／期待（expect）しなくてもよい。 The UE may assume/expect that XDD resources are not configured in specific time resources associated with DL reference signals (eg, DL reference signals for measurement). Also, the UE may not assume/expect that the XDD resource will be configured in a specific time resource associated with the DL reference signal (eg, DL reference signal for measurement).
　当該ＤＬ参照信号に関連する特定の時間リソースは、例えば、ＤＬ参照信号がマップされる時間リソース（例えば、シンボル）、ＤＬ参照信号のマッピングされる時間リソースを含む時間的に前／後の特定数（例えば、１）の時間リソース（例えば、シンボル）、及び、ＤＬ参照信号を含む時間リソース（例えば、スロット）、の少なくとも１つであってもよい。 A specific time resource associated with the DL reference signal is, for example, a time resource (e.g., symbol) to which the DL reference signal is mapped, a specific number of temporally before/after including the time resource to which the DL reference signal is mapped. (eg, 1) time resources (eg, symbols) and/or time resources (eg, slots) including DL reference signals.
　当該ＤＬ参照信号は、ＳＳＢ、ＣＳＩ－ＲＳ、モビリティのためのＣＳＩ－ＲＳ、ＲＳＳＩ測定用リソース、及び、ＰＲＳの少なくとも１つであってもよい。 The DL reference signal may be at least one of SSB, CSI-RS, CSI-RS for mobility, RSSI measurement resource, and PRS.
　例えば、ＤＬ参照信号の時間リソースが上位レイヤパラメータ／ＤＣＩにより設定されてもよい。この場合、ＵＥは、設定されたＤＬ参照信号の時間リソース（又は、当該時間リソースを含む時間的に前／後の特定数の時間リソース、当該時間リソースを含むスロット）に対して、ＸＤＤリソースが設定されないと想定してもよい。 For example, the time resource of the DL reference signal may be configured by a higher layer parameter/DCI. In this case, the UE, for the time resources of the configured DL reference signal (or a specific number of temporally forward / backward time resources including the time resources, slots including the time resources), the XDD resource is It may be assumed that it is not set.
　また、ＵＥは、ＤＬ参照信号に関連する特定の時間リソースにおいて、ＸＤＤリソースが設定されると想定／期待してもよい。 Also, the UE may assume/expect that the XDD resource will be configured in a specific time resource associated with the DL reference signal.
　このとき、ＵＥは、ＸＤＤリソースと時間領域で重複するＤＬ参照信号に基づくメジャメント（又は、ＤＬ参照信号に基づくメジャメントの報告）を行わなくてもよい。また、ＵＥは、当該ＤＬ参照信号の受信を行わなくてもよい。また、ＵＥは、ＤＬ参照信号の受信に関する設定／指示を無視してもよい。 At this time, the UE does not need to perform measurements based on DL reference signals that overlap in the time domain with XDD resources (or report measurements based on DL reference signals). Also, the UE may not receive the DL reference signal. Also, the UE may ignore the configuration/instruction regarding reception of DL reference signals.
　ＤＬ参照信号の時間リソース／ＸＤＤリソースは、上位レイヤパラメータ／ＤＣＩによりそれぞれ別々に設定されてもよい。ＤＬ参照信号の時間リソースの一部がＸＤＤリソースと重複する場合、ＵＥは、当該ＤＬ参照信号に基づくメジャメント（又は、ＤＬ参照信号に基づくメジャメントの報告）を行わなくてもよい。あるいは、ＵＥは、ＸＤＤリソースと重複しないＤＬ参照信号の一部のリソースに基づくメジャメント（又は、当該一部のリソースに基づくメジャメントの報告）を行ってもよい。 The time resources/XDD resources of the DL reference signal may be configured separately by higher layer parameters/DCI. When part of the time resource of the DL reference signal overlaps with the XDD resource, the UE does not need to perform measurements based on the DL reference signal (or report measurements based on the DL reference signal). Alternatively, the UE may perform measurements based on some resources of the DL reference signal that do not overlap with the XDD resources (or report measurements based on the part of the resources).
　また、ＵＥは、ＸＤＤリソースにおけるメジャメントに関するＵＥ能力情報（UE　Capability　Information）を報告してもよい。当該ＵＥ能力情報は、ＵＥが、ＸＤＤリソースにおいてメジャメントを行うことが可能か否かで定義されてもよい。 Also, the UE may report UE Capability Information regarding measurements in XDD resources. The UE capability information may be defined by whether or not the UE can perform measurements on XDD resources.
　ＵＥは、当該ＵＥ能力情報（例えば、ＸＤＤリソースにおけるメジャメントが可能であることを示す情報）を報告した場合、ＤＬ参照信号に関連する特定の時間リソースにおいて、ＸＤＤリソースが設定されると想定／期待してもよい。 When the UE reports the UE capability information (for example, information indicating that the XDD resource can be measured), the UE assumes/expects that the XDD resource is configured in a specific time resource related to the DL reference signal. You may
　当該ＤＬ参照信号に関連する特定の時間リソースは、例えば、ＤＬ参照信号がマップされる時間リソース（例えば、シンボル）、ＤＬ参照信号のマッピングされる時間リソースを含む時間的に前／後の特定数（例えば、１）の時間リソース（例えば、シンボル）、及び、ＤＬ参照信号を含む時間リソース（例えば、スロット）、の少なくとも１つであってもよい。 A specific time resource associated with the DL reference signal is, for example, a time resource (e.g., symbol) to which the DL reference signal is mapped, a specific number of temporally before/after including the time resource to which the DL reference signal is mapped. (eg, 1) time resources (eg, symbols) and/or time resources (eg, slots) including DL reference signals.
　当該ＤＬ参照信号は、ＳＳＢ、ＣＳＩ－ＲＳ、モビリティのためのＣＳＩ－ＲＳ、ＲＳＳＩ測定用リソース、及び、ＰＲＳの少なくとも１つであってもよい。 The DL reference signal may be at least one of SSB, CSI-RS, CSI-RS for mobility, RSSI measurement resource, and PRS.
　また、ＵＥは、特定の上位レイヤシグナリングに基づいて、ＤＬ参照信号と重複するＸＤＤリソースの設定を無視するかを判断してもよい。ＵＥは、特定の上位レイヤパラメータを受信した場合、ＤＬ参照信号と重複するＸＤＤリソースの設定を無視すると判断してもよい。 Also, the UE may determine whether to ignore the configuration of XDD resources that overlap with the DL reference signal based on specific higher layer signaling. The UE may decide to ignore the configuration of XDD resources that overlap with the DL reference signal if certain higher layer parameters are received.
　なお、当該ＵＥ能力情報は、特定の周波数レンジ（例えば、ＦＲ２）向けに規定されてもよいし、各周波数レンジ（例えば、ＦＲ１／ＦＲ２（ＦＲ２－１／ＦＲ２－２））向けに別々に規定されてもよい。 Note that the UE capability information may be defined for a specific frequency range (eg, FR2) or defined separately for each frequency range (eg, FR1/FR2 (FR2-1/FR2-2)). may be
　図５Ａ及び図５Ｂは、第１の実施形態に係るＸＤＤリソースの設定の一例を示す図である。図５Ａに示す例では、ＤＬ参照信号がマッピングされるシンボルにおいてＸＤＤリソースが設定されない。図５Ａに示す例では、ＤＬ参照信号がマッピングされるシンボル以外のリソースにおいて、ＸＤＤリソースの設定が可能である。 FIGS. 5A and 5B are diagrams showing an example of XDD resource settings according to the first embodiment. In the example shown in FIG. 5A, XDD resources are not configured in symbols to which DL reference signals are mapped. In the example shown in FIG. 5A, XDD resources can be configured in resources other than symbols to which DL reference signals are mapped.
　図５Ｂに示す例では、ＤＬ参照信号がマッピングされるスロットにおいてＸＤＤリソースが設定されない。図５Ｂに示す例では、ＤＬ参照信号がマッピングされるスロット以外のリソースにおいて、ＸＤＤリソースの設定が可能である。 In the example shown in FIG. 5B, XDD resources are not configured in slots to which DL reference signals are mapped. In the example shown in FIG. 5B, XDD resources can be configured in resources other than slots to which DL reference signals are mapped.
　以上第１の実施形態によれば、ＸＤＤリソースを利用する場合であっても、適切にメジャメントの動作を行うことが可能になる。 As described above, according to the first embodiment, it is possible to appropriately perform the measurement operation even when using the XDD resource.

Each of the one or more periods (frames) that make up a radio frame may be called a subframe. Furthermore, a subframe may consist of one or more slots in the time domain. A subframe may be a fixed time length (eg, 1 ms) independent of numerology.
　ここで、ニューメロロジーは、ある信号又はチャネルの送信及び受信の少なくとも一方に適用される通信パラメータであってもよい。ニューメロロジーは、例えば、サブキャリア間隔（SubCarrier　Spacing（ＳＣＳ））、帯域幅、シンボル長、サイクリックプレフィックス長、送信時間間隔（Transmission　Time　Interval（ＴＴＩ））、ＴＴＩあたりのシンボル数、無線フレーム構成、送受信機が周波数領域において行う特定のフィルタリング処理、送受信機が時間領域において行う特定のウィンドウイング処理などの少なくとも１つを示してもよい。 Here, a numerology may be a communication parameter applied to at least one of transmission and reception of a certain signal or channel.

Each minislot may consist of one or more symbols in the time domain. A minislot may also be referred to as a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in time units larger than a minislot may be referred to as PDSCH (PUSCH) Mapping Type A. PDSCH (or PUSCH) transmitted using minislots may be referred to as PDSCH (PUSCH) mapping type B.
　無線フレーム、サブフレーム、スロット、ミニスロット及びシンボルは、いずれも信号を伝送する際の時間単位を表す。無線フレーム、サブフレーム、スロット、ミニスロット及びシンボルは、それぞれに対応する別の呼称が用いられてもよい。なお、本開示におけるフレーム、サブフレーム、スロット、ミニスロット、シンボルなどの時間単位は、互いに読み替えられてもよい。 Radio frames, subframes, slots, minislots and symbols all represent time units when transmitting signals. Radio frames, subframes, slots, minislots, and symbols may be referred to by other corresponding designations.

　例えば、１サブフレームはＴＴＩと呼ばれてもよいし、複数の連続したサブフレームがＴＴＩと呼ばれてよいし、１スロット又は１ミニスロットがＴＴＩと呼ばれてもよい。つまり、サブフレーム及びＴＴＩの少なくとも一方は、既存のＬＴＥにおけるサブフレーム（１ｍｓ）であってもよいし、１ｍｓより短い期間（例えば、１－１３シンボル）であってもよいし、１ｍｓより長い期間であってもよい。なお、ＴＴＩを表す単位は、サブフレームではなくスロット、ミニスロットなどと呼ばれてもよい。 For example, one subframe may be called a TTI, a plurality of consecutive subframes may be called a TTI, and one slot or one minislot may be called a TTI.

For example, in the LTE system, a base station performs scheduling to allocate radio resources (frequency bandwidth, transmission power, etc. that can be used by each user terminal) to each user terminal on a TTI basis. Note that the definition of TTI is not limited to this.
　ＴＴＩは、チャネル符号化されたデータパケット（トランスポートブロック）、コードブロック、コードワードなどの送信時間単位であってもよいし、スケジューリング、リンクアダプテーションなどの処理単位となってもよい。なお、ＴＴＩが与えられたとき、実際にトランスポートブロック、コードブロック、コードワードなどがマッピングされる時間区間（例えば、シンボル数）は、当該ＴＴＩよりも短くてもよい。 A TTI may be a transmission time unit such as a channel-encoded data packet (transport block), code block, or codeword, or may be a processing unit such as scheduling and link adaptation. Note that when a TTI is given, the time interval (for example, the number of symbols) in which transport blocks, code blocks, codewords, etc. are actually mapped may be shorter than the TTI.

Also, the number of slots (the number of mini-slots) constituting the minimum time unit of the scheduling may be controlled.

A TTI that is shorter than a normal TTI may be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a minislot, a subslot, a slot, and the like.
　なお、ロングＴＴＩ（例えば、通常ＴＴＩ、サブフレームなど）は、１ｍｓを超える時間長を有するＴＴＩで読み替えてもよいし、ショートＴＴＩ（例えば、短縮ＴＴＩなど）は、ロングＴＴＩのＴＴＩ長未満かつ１ｍｓ以上のＴＴＩ長を有するＴＴＩで読み替えてもよい。 Note that the long TTI (e.g., normal TTI, subframe, etc.) may be replaced with a TTI having a time length exceeding 1 ms, and the short TTI (e.g., shortened TTI, etc.) is less than the TTI length of the long TTI and 1 ms A TTI having the above TTI length may be read instead.
