Description

ユーザ端末及び無線通信方法User terminal and wireless communication method
　本開示は、次世代移動通信システムにおけるユーザ端末及び無線通信方法に関する。 The present disclosure relates to a user terminal and a wireless communication method in a next-generation mobile communication system.
　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）、New　Radio（ＮＲ）、３ＧＰＰ　Ｒｅｌ．１５以降などともいう）も検討されている。 A successor system to LTE (for example, 5th generation mobile communication system (5G), 5G+(plus), New Radio (NR), 3GPP Rel.15 or later) is also under consideration.
　既存のＬＴＥシステム（例えば、ＬＴＥ　Ｒｅｌ．８－１４）では、ユーザ端末（User　Equipment（ＵＥ））は、下り制御チャネル（例えば、Physical　Downlink　Control　Channel（ＰＤＣＣＨ））を介して伝送される下り制御情報（Downlink　Control　Information（ＤＣＩ）、ＤＬアサインメント等ともいう）に基づいて、下り共有チャネル（例えば、Physical　Downlink　Shared　Channel（ＰＤＳＣＨ））の受信を制御する。また、ユーザ端末は、ＤＣＩ（ＵＬグラント等ともいう）に基づいて、上り共有チャネル（例えば、Physical　Uplink　Shared　Channel（ＰＵＳＣＨ））の送信を制御する。 In the existing LTE system (for example, LTE Rel.8-14), the user terminal (User Equipment (UE)) has downlink control information transmitted via a downlink control channel (for example, Physical Downlink Control Channel (PDCCH)). Controls the reception of downlink shared channels (for example, Physical Downlink Shared Channel (PDSCH)) based on (also called Downlink Control Information (DCI), DL assignment, etc.). Further, the user terminal controls transmission of an uplink shared channel (for example, Physical Uplink Shared Channel (PUSCH)) based on DCI (also referred to as UL grant).
　既存のＬＴＥシステム（例えば、ＬＴＥ　Ｒｅｌ．８－１３）においては、ユーザ端末（User　Equipment（ＵＥ））が基地局に対して、周期的及び／又は非周期的にチャネル状態情報（Channel　State　Information（ＣＳＩ））を送信する。ＵＥは、上り制御チャネル（Physical　Uplink　Control　Channel（ＰＵＣＣＨ））及び／又は上り共有チャネル（Physical　Uplink　Shared　Channel（ＰＵＳＣＨ））を用いて、ＣＳＩを送信する。 In an existing LTE system (for example, LTE Rel. 8-13), a user terminal (User Equipment (UE)) periodically and/or aperiodically transmits channel state information (Channel State Information (UE)) to a base station. CSI)) is transmitted. The UE transmits the CSI using an uplink control channel (Physical Uplink Control Channel (PUCCH)) and/or an uplink shared channel (Physical Uplink Shared Channel (PUSCH)).
　将来の無線通信システム（例えば、ＮＲ）において、複数の送信ポイント（送受信ポイント、パネルなど）を用いる送信が検討されている。 In future wireless communication systems (eg NR), transmission using multiple transmission points (transmission/reception points, panels, etc.) is being considered.
　しかしながら、複数の送信ポイントの間でチャネル状態情報（ＣＳＩ）が異なる。複数の送信ポイントに対するＣＳＩ報告が適切に行われなければ、通信品質が劣化するおそれがある。 However, the channel state information (CSI) differs between multiple transmission points. If CSI reporting is not properly performed to a plurality of transmission points, communication quality may deteriorate.
　そこで、本開示は、複数の送信ポイントに対するＣＳＩ報告を適切に行うユーザ端末及び無線通信方法を提供することを目的の１つとする。 Therefore, an object of the present disclosure is to provide a user terminal and a wireless communication method that appropriately perform CSI reporting to a plurality of transmission points.
　本開示の一態様に係るユーザ端末は、複数の送信ポイントにそれぞれ対応する複数のチャネル状態情報（ＣＳＩ）報告に関する設定情報を受信し、前記複数のＣＳＩ報告に関する少なくとも１つの指示を受信する受信部と、前記少なくとも１つの指示に基づいて、前記複数のＣＳＩ報告を行う制御部と、を有することを特徴とする。 A user terminal according to an aspect of the present disclosure receives a setting information regarding a plurality of channel state information (CSI) reports respectively corresponding to a plurality of transmission points, and receives at least one instruction regarding the plurality of CSI reports. And a control unit that performs the plurality of CSI reports based on the at least one instruction.
　本開示の一態様によれば、複数の送信ポイントに対するＣＳＩ報告を適切に行うことができる。 According to one aspect of the present disclosure, it is possible to appropriately perform CSI reporting to a plurality of transmission points.

（複数ＴＲＰ送信）
　将来の無線通信システム（例えば、Ｒｅｌ．１６以降）では、複数の送信ポイントからそれぞれノンコヒーレントなＤＬ（例えば、ＰＤＳＣＨ）送信が行われることが検討されている。複数の送信ポイントからノンコヒーレントとなるＤＬ信号（又は、ＤＬチャネル）を協調して行う送信は、ＮＣＪＴ（Non-Coherent　Joint　Transmission）と呼んでもよい。 (Multiple TRP transmission)
In future wireless communication systems (for example, Rel. 16 and later), it is considered that non-coherent DL (for example, PDSCH) transmission is performed from each of a plurality of transmission points. Transmission in which DL signals (or DL channels) that are non-coherent from a plurality of transmission points are cooperatively performed may be called NCJT (Non-Coherent Joint Transmission).
　また、本開示において、送信ポイントは、送受信ポイント（Transmission/Reception　Point：ＴＲＰ）、パネル（panel、アンテナパネル、複数のアンテナ素子）、アンテナ、アンテナポート、又はセルと読み替えられてもよい。送信ポイント（ＴＲＰ、パネルなど）は、例えば、ビーム、spatial　filter、Reference　Signal（ＲＳ）リソース、擬似コロケーション（Quasi　Co-Location（ＱＣＬ））、送信設定指示（Transmission　Configuration　Indication（ＴＣＩ））、又はそれらをグルーピングした概念で置き換えることができる。 Also, in the present disclosure, a transmission point may be read as a transmission/reception point (Transmission/Reception Point: TRP), a panel (panel, an antenna panel, a plurality of antenna elements), an antenna, an antenna port, or a cell. The transmission point (TRP, panel, etc.) is, for example, a beam, a spatial filter, a Reference Signal (RS) resource, a pseudo collocation (Quasi Co-Location (QCL)), a transmission configuration indication (Transmission Configuration Indication (TCI)), or those. Can be replaced by the concept of grouping.
　複数の送信ポイントからそれぞれ送信されるノンコヒーレントのＰＤＳＣＨのスケジューリングを１以上のDownlink　Control　Information（ＤＣＩ）を用いて制御することも想定される。一例として、複数の送信ポイントから送信されるＰＤＳＣＨをスケジューリングするために、複数の下り制御チャネル（例えば、ＰＤＣＣＨ）及びＤＣＩの少なくとも一つが利用される。 It is also envisioned to control the scheduling of non-coherent PDSCHs transmitted from multiple transmission points using one or more Downlink Control Information (DCI). As an example, at least one of a plurality of downlink control channels (for example, PDCCH) and DCI is used to schedule PDSCHs transmitted from a plurality of transmission points.
　この場合、異なる送信ポイントからそれぞれ送信されるＰＤＳＣＨを同じリソース（例えば、時間及び周波数リソース）に割当てて送信することも考えられる。例えば、同じコードワード（ＣＷ）に対応するＰＤＳＣＨを異なるレイヤで送信する構成（図１Ａ参照）、異なるＣＷに対応するＰＤＳＣＨを送信する構成（図１Ｂ参照）がサポートされる。 In this case, it is possible to allocate PDSCHs transmitted from different transmission points to the same resource (for example, time and frequency resource) and transmit the same. For example, a configuration for transmitting PDSCHs corresponding to the same codeword (CW) in different layers (see FIG. 1A) and a configuration for transmitting PDSCHs corresponding to different CWs (see FIG. 1B) are supported.
　図１Ａでは、第１の送信ポイントから送信されるＰＤＳＣＨ（ＣＷ＃１に対応）がレイヤ１及び２の少なくとも一つを利用し、第２の送信ポイントから送信されるＰＤＳＣＨ（ＣＷ＃１に対応）がレイヤ３及び４の少なくとも一つを利用して同じ時間及び周波数リソースに割当てられる場合を示している。 In FIG. 1A, the PDSCH (corresponding to CW#1) transmitted from the first transmission point uses at least one of layers 1 and 2 and the PDSCH (corresponding to CW#1) transmitted from the second transmission point. ) Is assigned to the same time and frequency resource using at least one of layers 3 and 4.
　図１Ｂでは、第１の送信ポイントから送信されるＰＤＳＣＨ（ＣＷ＃１に対応）と、第２の送信ポイントから送信されるＰＤＳＣＨ（ＣＷ＃２に対応）が同じ時間及び周波数リソースに割当てられる場合を示している。 In FIG. 1B, when the PDSCH (corresponding to CW#1) transmitted from the first transmission point and the PDSCH (corresponding to CW#2) transmitted from the second transmission point are allocated to the same time and frequency resource. Is shown.
　また、図１Ｃに示すように、複数ＴＲＰ送信において、複数のＰＤＳＣＨが、異なるMultiple　Input　Multiple　Output（ＭＩＭＯ）レイヤにおいて送信されてもよい。また、複数のＰＤＳＣＨの時間リソース及び周波数リソースが重複してもよい。 Also, as shown in FIG. 1C, in multiple TRP transmission, multiple PDSCHs may be transmitted in different Multiple Input Multiple Output (MIMO) layers. Also, the time resources and frequency resources of multiple PDSCHs may overlap.
　ＵＥは、複数のＴＲＰを用いる通信（例えば、複数ＴＲＰ送信）を上位レイヤシグナリング（設定情報）によって設定されてもよい。ＵＥは、複数のＴＲＰを用いる通信のために、複数のＴＲＰにそれぞれ対応する複数のリソースの割り当てを示す情報（上位レイヤシグナリング及びＤＣＩの少なくとも１つ）を通知されてもよい。 The UE may set communication using multiple TRPs (for example, multiple TRP transmissions) by upper layer signaling (configuration information). For communication using a plurality of TRPs, the UE may be notified of information (at least one of higher layer signaling and DCI) indicating allocation of a plurality of resources respectively corresponding to the plurality of TRPs.
　複数のＴＲＰは、同期（synchronous）ネットワークに属していてもよいし、非同期（asynchronous）ネットワークに属していてもよい。また、複数のＴＲＰは、理想バックホール（ideal　backhaul）を介して接続されてもよいし、非理想バックホール（non-ideal　backhaul）を介して接続されてもよい。 -A plurality of TRPs may belong to a synchronous network or may belong to an asynchronous network. Further, a plurality of TRPs may be connected via an ideal backhaul or a non-ideal backhaul.
（ＢＷＰ）
　将来の無線通信システム（例えば、ＮＲ、５Ｇ又は５Ｇ＋）では、既存のＬＴＥシステム（例えば、ＬＴＥ　Ｒｅｌ．８－１３）より広い帯域幅（例えば、１００～８００ＭＨｚ）のキャリア（コンポーネントキャリア（Component　Carrier：ＣＣ）、セル又はシステム帯域等ともいう）を割り当てることが検討されている。 (BWP)
In a future wireless communication system (eg, NR, 5G or 5G+), a carrier (component carrier (Component Carrier: 100 to 800 MHz)) having a wider bandwidth (eg, 100 to 800 MHz) than an existing LTE system (eg, LTE Rel.8-13). CC), cell or system band, etc.) is being considered.
　一方、当該将来の無線通信システムでは、当該キャリア全体で送信及び／又は受信（送受信）する能力（capability）を有するユーザ端末（Wideband(WB)　UE、single　carrier　WB　UE等ともいう）と、当該キャリア全体で送受信する能力を有しないユーザ端末（Bandwidth（BW）　reduced　UE等ともいう）とが混在することが想定される。 On the other hand, in the future wireless communication system, a user terminal (also referred to as Wideband (WB) UE, single carrier WB UE, etc.) having a capability of transmitting and/or receiving (transmitting/receiving) in the entire carrier, It is assumed that user terminals (also called Bandwidth (BW) reduced UE, etc.) that do not have the ability to send and receive as a whole are mixed.
　このように、将来の無線通信システムでは、サポートする帯域幅において複数のユーザ端末が混在すること（various　BW　UE　capabilities）が想定されるため、キャリア内に一以上の部分的な周波数帯域を準静的に設定（configure）することが検討されている。当該キャリア内の各周波数帯域（例えば、５０ＭＨｚ又は２００ＭＨｚなど）は、部分帯域又は帯域幅部分（Bandwidth　part：ＢＷＰ）等と呼ばれる。 In this way, in future wireless communication systems, it is assumed that multiple user terminals are mixed in the supported bandwidth (various BW UE capabilities), so one or more partial frequency bands are quasi-static in the carrier. It is being considered to configure it dynamically. Each frequency band (for example, 50 MHz or 200 MHz) in the carrier is called a partial band or a bandwidth part (BWP).
　ＢＷＰのアクティブ化（activation）又は非アクティブ化（deactivation）が制御されてもよい。ここで、ＢＷＰのアクティブ化とは、当該ＢＷＰを利用可能な状態である（又は当該利用可能な状態に遷移する）ことであり、ＢＷＰの設定情報（configuration）（ＢＷＰ設定情報）のアクティブ化又は有効化等とも呼ばれる。また、ＢＷＰの非アクティブ化とは、当該ＢＷＰを利用不可能な状態である（又は当該利用不可能な状態に遷移する）ことであり、ＢＷＰ設定情報の非アクティブ化又は無効化等とも呼ばれる。ＢＷＰがスケジューリングされることで、このＢＷＰがアクティブ化されることになる。また、当該複数のＢＷＰの少なくとも一つのアクティブ化又は非アクティブ化が制御されてもよい。 The activation or deactivation of BWP may be controlled. Here, activation of the BWP means that the BWP is in a usable state (or transits to the usable state), and activation of BWP setting information (configuration) (BWP setting information) or Also called activation etc. The deactivation of the BWP means that the BWP is in an unusable state (or transits to the unusable state), and is also called deactivation or invalidation of the BWP setting information. Scheduling the BWP will activate the BWP. Further, activation or deactivation of at least one of the plurality of BWPs may be controlled.
（リソースセッティング及び報告セッティング）
　Ｒｅｌ．１５においては、ＵＥが、ＣＳＩのために、少なくとも１つのリソースセッティング（ＣＳＩ－ＲＳリソース設定（configuration））と、少なくとも１つの報告セッティング（ＣＳＩ報告設定（configuration））と、を設定されることが規定されている。 (Resource setting and reporting setting)
Rel. At 15, the UE may be configured for CSI with at least one resource setting (CSI-RS resource configuration) and at least one reporting setting (CSI reporting configuration). It is prescribed.
　例えば、図２に示すように、ＵＥは、リソースセッティング＃０，＃１，＃２を上位レイヤパラメータ（例えば、CSI-ResourceConfig）によって設定されてもよい。各リソースセッティングは、複数のＣＳＩ－ＲＳリソースセット（例えば、ＣＳＩ－ＲＳリソースセット＃０、＃１，＃２）を含んでもよい。各ＣＳＩ－ＲＳリソースセットは、複数のＣＳＩ－ＲＳリソースを含んでもよい。 For example, as shown in FIG. 2, the UE may set resource settings #0, #1, and #2 by an upper layer parameter (for example, CSI-ResourceConfig). Each resource setting may include multiple CSI-RS resource sets (eg, CSI-RS resource sets #0, #1, #2). Each CSI-RS resource set may include multiple CSI-RS resources.
　ＵＥは、複数の報告セッティング＃０，＃１を上位レイヤパラメータ（例えば、CSI-ReportConfig）によって設定されてもよい。報告セッティング＃０は、リソースセッティング＃０，＃１に関連付けられていてもよく、報告セッティング＃１は、リソースセッティング＃０，＃２に関連付けられていてもよい。 The UE may configure multiple report settings #0, #1 by upper layer parameters (eg CSI-ReportConfig). Report setting #0 may be associated with resource settings #0, #1, and report setting #1 may be associated with resource settings #0, #2.
　Ｒｅｌ．１５においては、ＣＳＩ－ＲＳ（ＣＳＩ－ＲＳリソース）設定として、周期的ＣＳＩ－ＲＳ（Ｐ－ＣＳＩ－ＲＳ）、セミパーシステント（semi-persistent：準持続的）ＣＳＩ－ＲＳ（ＳＰ－ＣＳＩ－ＲＳ）、非周期的ＣＳＩ－ＲＳ（Ａ－ＣＳＩ－ＲＳ）、がサポートされる。 Rel. In No. 15, as CSI-RS (CSI-RS resource) settings, periodic CSI-RS (P-CSI-RS), semi-persistent (semi-persistent) CSI-RS (SP-CSI-RS) ), aperiodic CSI-RS (A-CSI-RS), are supported.
　また、Ｒｅｌ．１５においては、ＣＳＩ報告として、周期的ＣＳＩ（Ｐ－ＣＳＩ）報告、セミパーシステントＣＳＩ（ＳＰ－ＣＳＩ）報告、非周期的ＣＳＩ（Ａ－ＣＳＩ）報告、がサポートされる。ＳＰ－ＣＳＩ報告として、ＰＵＣＣＨ上ＳＰ－ＣＳＩ報告（SP-CSI　Reporting　on　PUCCH）、ＰＵＳＣＨ上ＳＰ－ＣＳＩ報告（SP-CSI　Reporting　on　PUSCH）、がサポートされる。 Also, Rel. In 15, the periodic CSI (P-CSI) report, the semi-persistent CSI (SP-CSI) report, and the aperiodic CSI (A-CSI) report are supported as CSI reports.

　図３は、Ｒｅｌ．１５におけるＣＳＩ－ＲＳ設定に対するＣＳＩ報告のトリガリング又はアクティベーションの方法の一例を示す図である。 Figure 3 shows Rel. 16 is a diagram showing an example of a method of triggering or activating a CSI report for CSI-RS configuration in FIG.
　ＳＲＳ（Sounding　Reference　Signal）送信が、Ｐ－ＳＲＳ、ＳＰ－ＳＲＳ、Ａ－ＳＲＳに分類されるのと同様、ＣＳＩ報告は、Ｐ－ＣＳＩ報告、ＳＰ－ＣＳＩ報告、Ａ－ＣＳＩ報告に分類されてもよい。 Just as SRS (Sounding Reference Signal) transmissions are classified into P-SRS, SP-SRS, and A-SRS, CSI reports are classified into P-CSI reports, SP-CSI reports, and A-CSI reports. Good.
　ＣＳＩ－ＲＳ設定としてＰ－ＣＳＩ－ＲＳが設定された場合、Ｐ－ＣＳＩ報告、ＰＵＣＣＨ上のＳＰ－ＣＳＩ報告、ＰＵＳＣＨ上のＳＰ－ＣＳＩ報告、Ａ－ＣＳＩ報告がサポートされる。Ｐ－ＣＳＩ報告は、ＲＲＣパラメータによって設定され、ＵＥは動的なトリガ（triggering）又はアクティベーション（activation）を受信しない。 When P-CSI-RS is set as CSI-RS setting, P-CSI report, SP-CSI report on PUCCH, SP-CSI report on PUSCH, and A-CSI report are supported. The P-CSI report is set by the RRC parameter and the UE does not receive any dynamic triggering or activation.
　ＳＰ－ＣＳＩ報告に対し、ＵＥは、ＰＵＣＣＨ上の報告のためのアクティベーションコマンドをＭＡＣ　ＣＥによって受信する、又はＰＵＳＣＨ上の報告のためのＤＣＩ上のトリガを受信する。当該ＤＣＩは、ＳＰ－ＣＳＩ報告用の無線ネットワーク一時識別子（Radio　Network　Temporary　Identifier：ＲＮＴＩ）（例えば、ＳＰ－ＣＳＩ－ＲＮＴＩ、ＳＰ－ＣＳＩ　Ｃ－ＲＮＴＩ（ＳＰ－ＣＳＩ　Cell－ＲＮＴＩ））によって巡回冗長検査（Cyclic　Redundancy　Check：ＣＲＣ）ビットがマスキング（スクランブル）されたＤＣＩであってもよい。ＵＥは、所定のディアクティベーション（リリース）信号を受信した場合、又はアクティベーションコマンド（トリガ）によって開始される所定のタイマが満了した場合、ＳＰ－ＣＳＩ－ＲＳの測定及びＳＰ－ＣＳＩ報告を停止してもよい。 For the SP-CSI report, the UE receives an activation command for reporting on PUCCH by MAC CE, or receives a trigger on DCI for reporting on PUSCH. The DCI is a cyclic redundancy check by a Radio Network Temporary Identifier (RNTI) for reporting SP-CSI (eg, SP-CSI-RNTI, SP-CSI C-RNTI (SP-CSI Cell-RNTI)). It may be DCI with (Cyclic Redundancy Check: CRC) bits masked (scrambled). The UE stops SP-CSI-RS measurement and SP-CSI reporting when it receives a predetermined deactivation (release) signal or when a predetermined timer started by an activation command (trigger) expires. You may.
　Ａ－ＣＳＩ報告は、ＤＣＩによってトリガされる。Ａ－ＣＳＩ報告は、アクティベーションコマンドを用いてもよい。 A-CSI reporting is triggered by DCI. The A-CSI report may use an activation command.
　ＣＳＩ－ＲＳ設定としてＳＰ－ＣＳＩ－ＲＳが設定された場合、ＰＵＣＣＨ上のＳＰ－ＣＳＩ報告、ＰＵＳＣＨ上のＳＰ－ＣＳＩ報告、Ａ－ＣＳＩ報告がサポートされる。 When SP-CSI-RS is set as the CSI-RS setting, SP-CSI report on PUCCH, SP-CSI report on PUSCH, and A-CSI report are supported.
　ＣＳＩ－ＲＳ設定としてＡ－ＣＳＩ－ＲＳが設定された場合、Ａ－ＣＳＩ報告がサポートされる。 When A-CSI-RS is set as the CSI-RS setting, A-CSI reporting is supported.
　複数のＴＲＰを用いる通信においては、異なるＴＲＰに対して異なるＣＳＩが必要となる。しかしながら、Ｒｅｌ．１５においては、１つのＴＲＰに対するＣＳＩが規定されているため、複数のＴＲＰを用いる通信において、複数のＴＲＰに対するＣＳＩの報告及び設定をどのように行うかが明らかでない。 In communication using multiple TRPs, different CSIs are required for different TRPs. However, Rel. In C.15, CSI for one TRP is defined, and therefore, in communication using a plurality of TRPs, it is not clear how to report and set CSI for a plurality of TRPs.
　そこで、本発明者らは、複数の送信ポイントにそれぞれ対応する複数のＣＳＩ報告の設定（例えば、リソースセッティング、報告セッティング）又は指示（例えば、アクティベーション、ディアクティベーション、又はトリガ）の動作を着想した。 Therefore, the inventors have conceived the operation of setting (eg, resource setting, report setting) or instruction (eg, activation, deactivation, or trigger) of a plurality of CSI reports respectively corresponding to a plurality of transmission points. did.

　以上の実施形態１－２によれば、複数のＴＲＰに対応する複数のＣＳＩ報告に対して、アクティベーション、ディアクティベーション、トリガの少なくとも１つを適切に行うことができる。また、１つのＰＤＣＣＨ又はＭＡＣ　ＣＥを用いて、アクティベーション、ディアクティベーション、トリガの少なくとも１つを行うため、シグナリングのオーバヘッドを抑えることができる。 According to the above-described Embodiment 1-2, at least one of activation, deactivation, and trigger can be appropriately performed on a plurality of CSI reports corresponding to a plurality of TRPs. Moreover, since at least one of activation, deactivation and trigger is performed using one PDCCH or MAC CE, signaling overhead can be suppressed.
＜実施形態２＞
　ＵＥは、異なるＴＲＰに対する複数の報告セッティングの間のマッピングを用いて、少なくとも１つの報告セッティングを決定してもよい。 <Embodiment 2>
The UE may use the mapping between multiple reporting settings for different TRPs to determine at least one reporting setting.
　Ｒｅｌ．１５においてＵＥは、図２に示すように、ＣＳＩ－ＲＳリソースセッティングと報告セッティングの間のマッピングを設定される。 Rel. At 15, the UE is configured with a mapping between CSI-RS resource settings and reporting settings, as shown in FIG.
　更に、ＵＥは、図６に示すように、異なる報告セッティングの間のマッピングを用いてもよい。 Furthermore, the UE may use the mapping between different reporting settings as shown in FIG.
　例えば、ＴＲＰ＃０用の報告セッティング＃０に、ＴＲＰ＃１用の報告セッティング＃１が関連付けられている場合、ＵＥは、ＴＲＰ＃０用の報告セッティング＃０をアクティベート、ディアクティベート、又はトリガされることに応じて、その報告セッティングに関連付けられたＴＲＰ＃１用の報告セッティング＃１をアクティベート、ディアクティベート、又はトリガされてもよい。 For example, if the reporting setting #0 for TRP#0 is associated with the reporting setting #1 for TRP#1, the UE activates, deactivates, or triggers the reporting setting #0 for TRP#0. In response, report setting #1 for TRP#1 associated with that report setting may be activated, deactivated, or triggered.
　ＵＥは、次の実施形態２－１、２－２の少なくとも１つに従ってマッピングを設定されてもよい。 The UE may be configured with mapping according to at least one of the following Embodiments 2-1 and 2-2.
　以上の実施形態２－１によれば、ＵＥは、マッピングを用いて、少なくとも１つのＴＲＰに対する報告セッティングを決定することができる。また、マッピングに関する情報をＵＥに通知する必要がないため、シグナリングのオーバヘッドを抑えることができる。 According to the above embodiment 2-1, the UE can determine the report setting for at least one TRP using the mapping. Moreover, since it is not necessary to notify the UE of information regarding mapping, signaling overhead can be suppressed.
《実施形態２－１》
　ＵＥは、異なるＴＲＰに対する報告セッティングの間の暗示的マッピングを用いてもよい。 <<Embodiment 2-1>>
The UE may use an implicit mapping between reporting settings for different TRPs.
　ＵＥは、次の選択肢１、２の少なくとも１つによって報告セッティングをアクティベートされてもよい。ＵＥは、同様にして、報告セッティングをディアクティベート又はトリガされてもよい。 UE may activate reporting settings by at least one of the following alternatives 1, 2. The UE may similarly deactivate or trigger reporting settings.
《《選択肢１》》
　異なるＴＲＰの間において、同じ報告セッティングＩＤ同士が関連付けられてもよい。 <<<<Option 1>>>>
The same report setting ID may be associated with each other between different TRPs.
　ＵＥは、ＴＲＰ＃ｉの報告セッティング＃Ｘをアクティベートされる場合、ＴＲＰ＃ｊの報告セッティング＃Ｘ（同じ報告セッティングＩＤ）もアクティベートされてもよい。 When the UE activates the report setting #X of TRP#i, the UE may also activate the report setting #X of TRP#j (the same report setting ID).
《《選択肢２》》
　異なるＴＲＰの間の報告セッティングＩＤが、特定の式によって関連付けられてもよい。 <<<<Option 2>>>>
Report setting IDs between different TRPs may be related by a particular formula.
　ＵＥは、ＴＲＰ＃ｉの報告セッティング＃Ｘ（Ｘ＝０，１，…，Ｎ－１）をアクティベートされる場合、ＴＲＰ＃ｊの報告セッティング＃（Ｎ－Ｘ－１）もアクティベートされてもよい。ここで、Ｎは報告セッティングの総数であってもよい。 If the UE activates the reporting setting #X (X=0, 1,..., N-1) of TRP#i, the reporting setting #(N−X−1) of TRP#j may also be activated. .. Here, N may be the total number of reporting settings.
《実施形態２－２》
　ＵＥは、ＵＥは、異なるＴＲＰに対する報告セッティングの間の明示的マッピングを用いてもよい。 <<Embodiment 2-2>>
The UE may use an explicit mapping between the reporting settings for the UE.
　ＵＥは、上位レイヤパラメータによって、複数の報告セッティングの間のマッピングを設定されてもよい。ＵＥは、複数のＴＲＰの１つの報告セッティングのアクティベーション、ディアクティベーション、トリガの少なくとも１つの指示を受信した場合、マッピングに基づいて、当該報告セッティングに関連付けられた、他のＴＲＰの報告セッティングに対して、同じ指示を適用してもよい。 UE may be configured with a mapping between multiple reporting settings by higher layer parameters. When the UE receives at least one indication of activation, deactivation, trigger of one reporting setting of multiple TRPs, the UE may report to another TRP's reporting setting associated with that reporting setting based on the mapping. Alternatively, the same instructions may be applied.
　例えば、図７に示すように、複数のＴＲＰを用いるケースに対する報告セッティングの上位レイヤパラメータ（ＲＲＣ情報要素、例えば、CSI-MeasConfig）が、報告セッティングのマッピングを示す情報（例えば、Ｌ１（レイヤ１、ＤＣＩ）におけるＳＰ－ＣＳＩ報告用のトリガ状態のリスト、CSI-SemiPersistentOnPUSCH-TriggerStateList）を含んでもよい。このリストは、当該報告マッピングに関連付けられた、他のＴＲＰの報告セッティング（ＣＳＩ報告設定）のＩＤ（例えば、CSI-SemiPersistentOnPUSCH-TriggerState、CSI-ReportConfigId）を示してもよい。 For example, as shown in FIG. 7, the upper layer parameter (RRC information element, eg, CSI-MeasConfig) of the report setting for the case of using multiple TRPs is information indicating the mapping of the report setting (eg, L1 (layer 1, CSI-SemiPersistentOnPUSCH-TriggerStateList), a list of trigger states for SP-CSI reporting in DCI). This list may indicate the ID (eg, CSI-SemiPersistentOnPUSCH-TriggerState, CSI-ReportConfigId) of the report setting (CSI report setting) of another TRP associated with the report mapping.
　ＴＲＰ＃０に対するリストに示される、関連付けられた報告セッティングＩＤは、ＴＲＰ＃１に対して設定される報告セッティングＩＤを示してもよい。ＴＲＰ＃１に対するリストに示される、関連付けられた報告セッティングＩＤは、ＴＲＰ＃０に対して設定される報告セッティングＩＤを示してもよい。 The associated report setting ID shown in the list for TRP#0 may indicate the report setting ID set for TRP#1. The associated report setting ID shown in the list for TRP#1 may indicate the report setting ID set for TRP#0.
　以上の実施形態２－２によれば、ＵＥは、マッピングを用いて、少なくとも１つのＴＲＰに対する報告セッティングを決定することができる。また、マッピングを柔軟に設定できる。 According to the above Embodiment 2-2, the UE can determine the report setting for at least one TRP by using the mapping. In addition, the mapping can be set flexibly.
