　また、ＮＲでは、端末に予めＰＤＳＣＨ（Physical Downlink Shared Channel）のリソースを設定しておき、ＤＣＩ（Downlink Control Information）でａｃｔｉｖａｔｉｏｎ／ｒｅｌｅａｓｅを行うダウンリンクＳＰＳ（Semi-Persistent Scheduling）が規定されており、これにより、低遅延のデータ受信が可能となっている（例えば、非特許文献１及び非特許文献２）。 Further, in NR, a downlink SPS (Semi-Persistent Scheduling) is defined in which PDSCH (Physical Downlink Shared Channel) resources are set in advance in the terminal and activation / release is performed by DCI (Downlink Control Information). This enables low-delay data reception (for example, Non-Patent Document 1 and Non-Patent Document 2).
　連続する複数のＤＬ（Downlink）スロットに対してＳＰＳによるＰＤＳＣＨがスケジューリングされる場合、当該ＰＤＳＣＨ受信に対応するＨＡＲＱ－ＡＣＫ（Hybrid automatic repeat request Acknowledgement）を送信するためのＰＵＣＣＨ（Physical Uplink Control Channel）が、ＤＬシンボル又はフレキシブルシンボルと衝突する可能性がある。 When PDSCH by SPS is scheduled for a plurality of consecutive DL (Downlink) slots, PUCCH (Physical Uplink Control Channel) for transmitting HARQ-ACK (Hybrid automatic repeat request Acknowledgement) corresponding to the PDSCH reception is performed. , DL symbol or flexible symbol may collide.
　そのため、ＨＡＲＱ－ＡＣＫ送信を次に使用可能なＰＵＣＣＨのタイミングまで遅延させる処理が想定される。しかしながら、ＨＡＲＱ－ＡＣＫ送信を遅延させた場合に、ＨＡＲＱ－ＡＣＫ送信に使用するリソースをどのように決定するかは不明であった。 Therefore, a process of delaying the HARQ-ACK transmission until the timing of the next usable PUCCH is assumed. However, it was unclear how to determine the resources used for HARQ-ACK transmission when the HARQ-ACK transmission was delayed.
　本発明は上記の点に鑑みてなされたものであり、基地局からデータを受信した端末が、当該データの受信に対応するフィードバック情報を基地局に送信するとき使用するリソースを決定することを目的とする。 The present invention has been made in view of the above points, and an object thereof is to determine a resource to be used when a terminal receiving data from a base station transmits feedback information corresponding to the reception of the data to the base station. And.
　開示の技術によれば、ＳＰＳ（Semi persistent scheduling）によるデータを基地局から受信する受信部と、有効な上りリンクリソースまで送信を延期する必要がある前記データに対するＨＡＲＱ－ＡＣＫ（Hybrid automatic repeat request Acknowledgement）フィードバック情報及びＰＵＣＣＨ（Physical Uplink Control Channel）リソース候補から前記フィードバック情報を送信するリソースを決定する制御部と、前記リソースにおいて前記フィードバック情報を前記基地局に送信する送信部とを有する端末が提供される。 According to the disclosed technology, HARQ-ACK (Hybrid automatic feedback request Acknowledgement) for the receiver that receives SPS (Semi persistent feedback) data from the base station and the data that needs to be postponed to a valid uplink resource. ) A terminal having a control unit for determining a resource for transmitting the feedback information from the feedback information and a PUCCH (Physical Uplink Control Channel) resource candidate and a transmission unit for transmitting the feedback information to the base station in the resource is provided. To.

　図１は、本発明の実施の形態における無線通信システムを説明するための図である。本発明の実施の形態における無線通信システムは、図１に示されるように、基地局１０及び端末２０を含む。図１には、基地局１０及び端末２０が１つずつ示されているが、これは例であり、それぞれ複数であってもよい。 FIG. 1 is a diagram for explaining a wireless communication system according to an embodiment of the present invention. The wireless communication system according to the embodiment of the present invention includes a base station 10 and a terminal 20 as shown in FIG. Although FIG. 1 shows one base station 10 and one terminal 20, this is an example, and each of them may be plural.
　基地局１０は、１つ以上のセルを提供し、端末２０と無線通信を行う通信装置である。無線信号の物理リソースは、時間領域及び周波数領域で定義され、時間領域はＯＦＤＭ（Orthogonal Frequency Division Multiplexing）シンボル数で定義されてもよいし、周波数領域はサブキャリア数又はリソースブロック数で定義されてもよい。また、時間領域におけるＴＴＩ（Transmission Time Interval）がスロット又はサブスロットであってもよいし、ＴＴＩがサブフレームであってもよい。 The base station 10 is a communication device that provides one or more cells and performs wireless communication with the terminal 20.

　基地局１０は、複数のセル（複数のＣＣ（コンポーネントキャリア））を束ねて端末２０と通信を行うキャリアアグリゲーションを行うことが可能である。キャリアアグリゲーションでは、１つのプライマリセル（PCell, Primary Cell）と１以上のセカンダリセル（SCell, Secondary Cell）が使用される。 The base station 10 can perform carrier aggregation that bundles a plurality of cells (a plurality of CCs (component carriers)) and communicates with the terminal 20. In carrier aggregation, one primary cell (PCell, Primary Cell) and one or more secondary cells (SCell, Secondary Cell) are used.
　基地局１０は、同期信号及びシステム情報等を端末２０に送信する。同期信号は、例えば、ＮＲ－ＰＳＳ及びＮＲ－ＳＳＳである。システム情報は、例えば、ＮＲ－ＰＢＣＨあるいはＰＤＳＣＨにて送信され、ブロードキャスト情報ともいう。図１に示されるように、基地局１０は、ＤＬ（Downlink）で制御信号又はデータを端末２０に送信し、ＵＬ（Uplink）で制御信号又はデータを端末２０から受信する。なお、ここでは、ＰＵＣＣＨ、ＰＤＣＣＨ等の制御チャネルで送信されるものを制御信号と呼び、ＰＵＳＣＨ、ＰＤＳＣＨ等の共有チャネルで送信されるものをデータと呼んでいるが、このような呼び方は一例である。 The base station 10 transmits a synchronization signal, system information, and the like to the terminal 20. Synchronous signals are, for example, NR-PSS and NR-SSS. The system information is transmitted by, for example, NR-PBCH or PDSCH, and is also referred to as broadcast information. As shown in FIG. 1, the base station 10 transmits a control signal or data to the terminal 20 by DL (Downlink), and receives the control signal or data from the terminal 20 by UL (Uplink). Here, what is transmitted on a control channel such as PUCCH or PDCCH is called a control signal, and what is transmitted on a shared channel such as PUSCH or PDSCH is called data. Such a name is an example. Is.
　端末２０は、スマートフォン、携帯電話機、タブレット、ウェアラブル端末、Ｍ２Ｍ（Machine-to-Machine）用通信モジュール等の無線通信機能を備えた通信装置である。図１に示されるように、端末２０は、ＤＬで制御信号又はデータを基地局１０から受信し、ＵＬで制御信号又はデータを基地局１０に送信することで、無線通信システムにより提供される各種通信サービスを利用する。なお、端末２０をＵＥと呼び、基地局１０をｇＮＢと呼んでもよい。 The terminal 20 is a communication device having a wireless communication function such as a smartphone, a mobile phone, a tablet, a wearable terminal, and a communication module for M2M (Machine-to-Machine).

　端末２０は、複数のセル（複数のＣＣ）を束ねて基地局１０と通信を行うキャリアアグリゲーションを行うことが可能である。キャリアアグリゲーションでは、１つのプライマリセルと１以上のセカンダリセルが使用される。また、ＰＵＣＣＨを有するＰＵＣＣＨ－ＳＣｅｌｌが使用されてもよい。 The terminal 20 can perform carrier aggregation that bundles a plurality of cells (a plurality of CCs) and communicates with the base station 10. Carrier aggregation uses one primary cell and one or more secondary cells. Moreover, PUCCH-S Cell having PUCCH may be used.
　図２は、ＤＣ（Dual connectivity）が実行される場合における無線通信システムの構成例を示す。図２に示すとおり、ＭＮ（Master Node）となる基地局１０Ａと、ＳＮ（Secondary Node）となる基地局１０Ｂが備えられる。基地局１０Ａと基地局１０Ｂはそれぞれコアネットワークに接続される。端末２０は基地局１０Ａと基地局１０Ｂの両方と通信を行うことができる。 FIG. 2 shows a configuration example of a wireless communication system when DC (Dual connectivity) is executed. As shown in FIG. 2, a base station 10A serving as an MN (MasterNode) and a base station 10B serving as an SN (SecondaryNode) are provided. Base station 10A and base station 10B are each connected to the core network. The terminal 20 can communicate with both the base station 10A and the base station 10B.
　ＭＮである基地局１０Ａにより提供されるセルグループをＭＣＧ（Master Cell Group）と呼び、ＳＮである基地局１０Ｂにより提供されるセルグループをＳＣＧ（Secondary Cell Group）と呼ぶ。また、ＤＣにおいて、ＭＣＧは１つのＰＣｅｌｌと１以上のＳＣｅｌｌから構成され、ＳＣＧは１つのＰＳＣｅｌｌ（Primary SCG Cell）と１以上のＳＣｅｌｌから構成される。 The cell group provided by the MN base station 10A is called an MCG (Master Cell Group), and the cell group provided by the SN base station 10B is called an SCG (Secondary Cell Group).

　図３を参照して、本発明の実施の形態における通信システムの基本的な動作例を説明する。この動作は、後述する実施例に対して基本的に共通の動作である。 A basic operation example of the communication system according to the embodiment of the present invention will be described with reference to FIG. This operation is basically a common operation with respect to the examples described later.
　Ｓ１０１において、ＲＲＣシグナリングにより、基地局１０は端末２０に、ダウンリンクＳＰＳの設定情報、ＰＵＣＣＨリソースの設定情報、スロットフォーマットの設定情報等を送信し、端末２０はこれらの設定情報を受信する。なお、本実施の形態は、ダウンリンクＳＰＳを対象としているので、以降、「ＳＰＳ」はダウンリンクＳＰＳを意味する。 In S101, the base station 10 transmits downlink SPS setting information, PUCCH resource setting information, slot format setting information, and the like to the terminal 20 by RRC signaling, and the terminal 20 receives these setting information. Since the present embodiment targets the downlink SPS, "SPS" hereinafter means the downlink SPS.
　スロットフォーマットの設定情報は、例えば、ｔｄｄ－ＵＬ－ＤＬ－ＣｏｎｆｉｇｕｒａｔｉｏｎＣｏｍｍｏｎあるいはｔｄｄ－ＵＬ－ＤＬ－ＣｏｎｆｉｇｕｒａｔｉｏｎＤｅｄｉｃａｔｅｄであり、この設定情報により１以上のスロットにおける各スロットの各シンボルにおけるＴＤＤ構成が、ＤＬ、ＵＬ、フレキシブルのいずれかであるかが設定される。以降、この設定情報をセミスタティックＴＤＤ設定情報と呼ぶ。また、フレキシブルのことをＦと記載する場合がある。端末２０は、基本的に、セミスタティックＴＤＤ設定情報に従って、各スロットの各シンボルのＤＬ／ＵＬ／Ｆを判断する。 The setting information of the slot format is, for example, tdd-UL-DL-ConnectionCommon or tdd-UL-DL-ConfigurationDedicated, and the TDD configuration in each symbol of each slot in one or more slots is DL, UL, and the setting information. Whether it is flexible or not is set. Hereinafter, this setting information will be referred to as semi-static TDD setting information. Further, flexible may be described as F. The terminal 20 basically determines DL / UL / F of each symbol of each slot according to the semi-static TDD setting information.
　また、Ｓ１０１における設定情報として、スロットフォーマットをダイナミックに切り替えることを可能とするための、スロットフォーマットの複数の候補が通知されてもよい。この設定情報は例えばＳｌｏｔＦｏｒｍａｔＣｏｍｂｉｎａｔｉｏｎｓＰｅｒＣｅｌｌである。この情報は、スロットフォーマット（ＳＦ）のＩＤからなる情報なので、以降、これをＳＦＩ設定情報と呼ぶ。 Further, as the setting information in S101, a plurality of candidates for the slot format may be notified to enable the dynamic switching of the slot format. This setting information is, for example, SlotFormatCombinationsPerCell. Since this information consists of slot format (SF) IDs, it will be referred to as SFI setting information hereafter.
　Ｓ１０２において、端末２０は、ＳＰＳの設定をａｃｔｉｖａｔｅするＤＣＩを基地局１０から受信し、Ｓ１０３において、ＳＰＳの設定によるＰＤＳＣＨリソースでデータを受信する。Ｓ１０４において、端末２０は、ＤＣＩにより指定された時間位置のスロットのＰＵＣＣＨリソース（ＵＬスケジューリングがある場合はＰＵＳＣＨリソースでもよい）で、ＳＰＳ　ＨＡＲＱ－ＡＣＫを基地局１０に送信する。以下、ＳＰＳの設定による１又は複数のＰＤＳＣＨリソースでのデータ受信に対応するＨＡＲＱ－ＡＣＫを「ＳＰＳ　ＨＡＲＱ－ＡＣＫ」と記載する。以下、なお、ＳＰＳ　ＨＡＲＱ－ＡＣＫをＨＡＲＱ－ＡＣＫと呼ぶ場合がある。また、ＨＡＲＱ－ＡＣＫをＨＡＲＱ情報、ＨＡＲＱ応答、フィードバック情報等と呼んでもよい。 In S102, the terminal 20 receives the DCI that activates the SPS setting from the base station 10, and in S103, receives the data in the PDSCH resource set by the SPS. In S104, the terminal 20 transmits SPS HARQ-ACK to the base station 10 with the PUCCH resource (or the PUSCH resource if there is UL scheduling) of the slot at the time position specified by DCI. Hereinafter, HARQ-ACK corresponding to data reception by one or more PDSCH resources by setting SPS is described as "SPS HARQ-ACK". Hereinafter, SPS HARQ-ACK may be referred to as HARQ-ACK. Further, HARQ-ACK may be referred to as HARQ information, HARQ response, feedback information and the like.
　端末２０は、Ｓ１０２又はその前後において、スロットフォーマットをダイナミックに指定するＤＣＩを基地局１０から受信する場合もある。このＤＣＩは、ＳＦＩ設定情報で設定された複数のスロットフォーマットのＩＤのうち、実際に使用するＩＤを指定する制御情報である。端末２０は、このＤＣＩでスロットフォーマットを指定された場合には、セミスタティックＴＤＤ設定情報に代えて、当該スロットフォーマットに従って、各スロットの各シンボルのＤＬ／ＵＬ／Ｆを判断する。このＤＣＩの情報をダイナミックＳＦＩ指定情報（又は、ダイナミックＳＦＩ、又はＳＦＩ）と呼ぶ。 The terminal 20 may receive DCI from the base station 10 that dynamically specifies the slot format at or before and after S102. This DCI is control information that specifies an ID that is actually used among a plurality of slot format IDs set in the SFI setting information. When the slot format is specified by this DCI, the terminal 20 determines DL / UL / F of each symbol of each slot according to the slot format instead of the semi-static TDD setting information. This DCI information is referred to as dynamic SFI designation information (or dynamic SFI, or SFI).
　前述したとおり、端末２０は、ＳＰＳによるデータ受信の度に、ａｃｔｉｖａｔｉｏｎ　ＤＣＩにより、ＰＵＣＣＨリソースでＨＡＲＱ－ＡＣＫを送信する時間位置（スロット）を指定される。 As described above, each time the terminal 20 receives data by the SPS, the activation DCI specifies a time position (slot) for transmitting HARQ-ACK with the PUCCH resource.
　しかしながら、特に、端末２０に複数の短周期のＳＰＳが設定される場合には、指定された時間位置のスロットにおけるＴＤＤのＤＬ／ＵＬの設定（セミスタティックＴＤＤ設定情報又はダイナミックＳＦＩ指定情報による設定）によっては、ＰＵＣＣＨリソースが設定されるシンボル位置が、ＤＬシンボルあるいはＦシンボルと衝突してしまい、ＨＡＲＱ－ＡＣＫを送信できないことが考えられる。 However, in particular, when a plurality of short-cycle SPS are set in the terminal 20, the DL / UL setting of the TDD in the slot at the specified time position (setting based on the semi-static TDD setting information or the dynamic SFI designation information). Depending on the situation, it is conceivable that the symbol position where the PUCCH resource is set collides with the DL symbol or the F symbol, and HARQ-ACK cannot be transmitted.
　ＰＵＣＣＨリソースと、ＤＬシンボルあるいはＦシンボルとが衝突した場合に、ＨＡＲＱ－ＡＣＫをドロップすることが考えられるが、ＨＡＲＱ－ＡＣＫをドロップすることでＰＤＳＣＨの再送が必要となる。そのため、ＨＡＲＱ－ＡＣＫのドロップは遅延が大きくなるため望ましくない。 It is conceivable to drop HARQ-ACK when the PUCCH resource collides with the DL symbol or F symbol, but by dropping HARQ-ACK, PDSCH retransmission is required. Therefore, dropping HARQ-ACK is not desirable because it causes a large delay.
　図４は、ＳＰＳ　ＨＡＲＱ－ＡＣＫの例を示す図である。図４に、上述した衝突の例が示される。図４の例では、ＰＤＳＣＨを受信したスロットの直後のスロットから３スロット目のスロットが、ＨＡＲＱ－ＡＣＫ送信のためのスロットとして指定されているが、当該スロットがＤＬに該当する場合に、ＨＡＲＱ－ＡＣＫがドロップされる。 FIG. 4 is a diagram showing an example of SPS HARQ-ACK. FIG. 4 shows an example of the collision described above. In the example of FIG. 4, the third slot from the slot immediately after the slot that received the PDSCH is designated as the slot for HARQ-ACK transmission, but when the slot corresponds to DL, HARQ- ACK is dropped.
　本実施の形態では、ＰＵＣＣＨリソースとＤＬシンボル／Ｆシンボルとの衝突によるＨＡＲＱ－ＡＣＫのドロップを回避可能としている。 In this embodiment, it is possible to avoid dropping HARQ-ACK due to a collision between the PUCCH resource and the DL symbol / F symbol.
　具体的には、例えば、図４に示すように、端末２０は、ＰＵＣＣＨリソースとＤＬシンボル／Ｆシンボルとの衝突が発生すると判断した場合に、次の利用可能なＵＬのリソースまで送信を延期してＨＡＲＱ－ＡＣＫを送信する。 Specifically, for example, as shown in FIG. 4, when the terminal 20 determines that a collision between a PUCCH resource and a DL symbol / F symbol occurs, transmission is postponed until the next available UL resource. HARQ-ACK is sent.
　３ＧＰＰ会合にて、ＴＤＤにおいてＰＵＣＣＨが少なくとも１つの「ＤＬ又はＦシンボル」と衝突することによるＳＰＳ　ＨＡＲＱ－ＡＣＫのドロップを回避するために、リリース１７の強化（enhancement）を行うことが合意されている。 At the 3GPP meeting, it was agreed to enhance Release 17 to avoid dropping SPS HARQ-ACK due to PUCCH colliding with at least one "DL or F symbol" in TDD. ..
　ＰＵＣＣＨが少なくとも１つの「ＤＬシンボル又はＦシンボル」と衝突することによるＳＰＳ　ＨＡＲＱ－ＡＣＫのドロップを回避するためのｅｎｈａｎｃｅｍｅｎｔの方法として、端末２０は、最初に利用可能な有効なＰＵＣＣＨリソースまでＨＡＲＱ－ＡＣＫ送信を延期する。 As an acknowledgment method to avoid dropping SPS HARQ-ACK due to the PUCCH colliding with at least one "DL symbol or F symbol", the terminal 20 has HARQ-ACK up to the first available valid PUCCH resource. Postpone transmission.
　ＳＰＳ　ＨＡＲＱ－ＡＣＫ送信を延期するため、いずれのＰＵＣＣＨリソースを使用してＳＰＳ　ＨＡＲＱ－ＡＣＫを送信するかを決定することは重要である。ＳＰＳ　ＨＡＲＱ－ＡＣＫを送信するために決定されたＰＵＣＣＨリソースが、他のＵＬチャネル（例えばＰＵＣＣＨ又はＰＵＳＣＨ）と時間領域でオーバラップしないか多重されない場合、データから対応するＨＡＲＱ－ＡＣＫまでのオフセットを示すＫ１値を有効なＰＵＣＣＨリソースが存在するスロット又はサブスロットまで増加させればよい。なお、延期には、例えば、Ｋ１値の最大値制限、延期するリソースが適用可能であるか否か等、他の制限が存在する可能性がある。 In order to postpone the SPS HARQ-ACK transmission, it is important to decide which PUCCH resource to use to transmit the SPS HARQ-ACK. If the PUCCH resource determined to transmit the SPS HARQ-ACK does not overlap or overlap with other UL channels (eg PUCCH or PUSCH) in the time domain, it indicates the offset from the data to the corresponding HARQ-ACK. The K1 value may be increased to the slot or subslot in which a valid PUCCH resource resides. In addition, there may be other restrictions on the postponement, such as the maximum value limit of the K1 value and whether or not the deferred resource is applicable.
　一方、延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫを送信するために決定されたＰＵＣＣＨリソースが、他のＵＬチャネル（例えばＰＵＣＣＨ又はＰＵＳＣＨ）と時間領域でオーバラップするか多重される場合、延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫ送信をいずれのスロット又はサブスロットで実行するか決定した結果は、ＵＬ多重化動作に影響を与える可能性がある。 On the other hand, if the PUCCH resource determined to transmit the deferred SPS HARQ-ACK overlaps or is multiplexed in the time domain with another UL channel (eg PUCCH or PUSCH), the deferred SPS HARQ- The result of deciding in which slot or subslot the ACK transmission is performed may affect the UL multiplexing operation.
　ここで、ＳＰＳ　ＨＡＲＱ－ＡＣＫの延期に関して、いずれのスロット又はサブスロットにおけるＰＵＣＣＨリソースを使用して送信するかを決定する必要がある。ＳＰＳ　ＨＡＲＱ－ＡＣＫを除く他のＵＣＩタイプ向けのＰＵＣＣＨリソースが、ＳＰＳ　ＨＡＲＱ－ＡＣＫを送信するリソースの候補となる場合、例えば、以下１）－３）に示される事項を決定する必要が生じる。 Here, regarding the postponement of SPS HARQ-ACK, it is necessary to determine which slot or subslot the PUCCH resource is used for transmission. When PUCCH resources for other UCI types other than SPS HARQ-ACK are candidates for resources to transmit SPS HARQ-ACK, for example, it is necessary to determine the items shown in 1) -3) below.
１）１つのスロット又はサブスロットにおける延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫを送信するＰＵＣＣＨリソース候補を定義する条件
２）１つのスロット又はサブスロットにおけるＰＵＣＣＨリソース候補
３）１つのスロット又はサブスロットにおけるＰＵＣＣＨリソース候補のうち、いずれの候補を使用するか 1) Conditions for defining PUCCH resource candidates for transmitting postponed SPS HARQ-ACK in one slot or subslot 2) PUCCH resource candidates in one slot or subslot 3) PUCCH resource candidates in one slot or subslot Which candidate to use
　そこで、上記１）－３）に示される事項を図５に示されるフローチャートで決定してもよい。図５は、本発明の実施の形態におけるＳＰＳ　ＨＡＲＱ－ＡＣＫ送信の例を説明するためのフローチャートである。ステップＳ２０１において、端末２０は、延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫ送信用のＰＵＣＣＨリソース候補を定める条件を決定する。なお、当該条件は、予め仕様により決定されていてもよいし、端末２０が動的に決定してもよい。 Therefore, the matters shown in 1) -3) above may be determined by the flowchart shown in FIG. FIG. 5 is a flowchart for explaining an example of SPS HARQ-ACK transmission according to the embodiment of the present invention. In step S201, the terminal 20 determines the conditions for determining the PUCCH resource candidate for the postponed SPS HARQ-ACK transmission. The conditions may be determined in advance by specifications, or may be dynamically determined by the terminal 20.

３）延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫ送信用のＰＵＣＣＨリソース候補は、仕様又はＲＲＣ設定に加えてＤＣＩによる通知により設定されてもよい。例えば、ＤＣＩフォーマットは、ＵＥ固有ＤＣＩが使用されてもよいし、データのスケジューリングを伴ってもよいし伴わなくてもよいし、新たなＤＣＩフォーマットが使用されてもよい。また、ＤＣＩフォーマットは、グループコモンＤＣＩが使用されてもよいし、既存機能の通知を伴ってもよいし伴わなくてもよいし、新たなＤＣＩフォーマットが使用されてもよい。 3) The postponed PUCCH resource candidate for SPS HARQ-ACK transmission may be set by notification by DCI in addition to the specification or RRC setting. For example, the DCI format may use UE-specific DCI, may or may not be accompanied by data scheduling, or a new DCI format may be used. Further, the DCI format may be a group common DCI, may or may not be accompanied by notification of existing functions, or a new DCI format may be used.
　ＤＣＩフィールドについて、１又は複数のフィールドが、ステップＳ２０１で決定される条件に基づいて決定されるＰＵＣＣＨリソース候補を通知してもよい。当該ＤＣＩフィールドは、新たなＤＣＩフィールドであってもよいし、既存のＤＣＩフィールドのうち、使用されない他の機能の目的（ＲＶ，ＨＰＮ，ＭＣＳ，ＦＤＲＡ等）のためのフィールドを再解釈するものであってもよい。 Regarding the DCI field, one or more fields may notify the PUCCH resource candidate determined based on the condition determined in step S201. The DCI field may be a new DCI field or is a reinterpretation of an existing DCI field for the purpose of other unused functions (RV, HPN, MCS, FDRA, etc.). There may be.
　ＤＣＩによる通知方法について、ステップＳ２０１における条件によって設定されたＰＵＣＣＨリソースは、複数のＰＵＣＣＨリソースグループに分割されてもよい。例えば、ＵＣＩ種別及び優先度に基づいて、ＰＵＣＣＨリソースは、７つのＰＵＣＣＨリソースグループ｛ＨＰ　ＳＰＳ　ＨＡＲＱ－ＡＣＫリソース、ＨＰ　ｄｙｎａｍｉｃ　ＨＡＲＱ－ＡＣＫリソース、ＨＰ　ＳＲリソース、ＬＰ　ＳＰＳ　ＨＡＲＱ－ＡＣＫリソース、ＬＰ　ＨＡＲＱ－ＡＣＫリソース、ＬＰ　ＳＲリソース、ＬＰ　ＣＳＩリソース｝に分割されてもよい。 Regarding the notification method by DCI, the PUCCH resource set by the condition in step S201 may be divided into a plurality of PUCCH resource groups.

The DCI notification field and field length may be set by RRC signaling or may be defined by specification.
　図６は、本発明の実施の形態におけるＳＰＳ　ＨＡＲＱ－ＡＣＫ送信に使用するリソースを通知する例（１）を示す図である。図６に示されるように、ＤＣＩが複数の場合は各フィールドが、ＤＣＩが１つの場合は各ビットが、ＲＲＣ設定又は仕様により延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫ送信用のＰＵＣＣＨリソース候補にマッピングされてもよい。図６の例では、ＨＰ　ｄｙｎａｍｉｃ　ＨＡＲＱ－ＡＣＫリソース及びＨＰ　ＳＰＳ　ＨＡＲＱ－ＡＣＫリソースが、ＰＵＣＣＨリソース候補として設定される。図６に示されるリソースグループは、ステップＳ２０１で決定された条件を適用し、ステップＳ２０２で決定されたＲＲＣ設定又は仕様に基づくリソースグループであってもよい。 FIG. 6 is a diagram showing an example (1) of notifying a resource used for SPS HARQ-ACK transmission in the embodiment of the present invention. As shown in FIG. 6, each field is mapped to a PUCCH resource candidate for SPS HARQ-ACK transmission postponed by the RRC setting or specification when there is a plurality of DCIs, and each bit is mapped to a PUCCH resource candidate when there is one DCI. May be good. In the example of FIG. 6, the HP dynamic HARQ-ACK resource and the HP SPS HARQ-ACK resource are set as PUCCH resource candidates. The resource group shown in FIG. 6 may be a resource group based on the RRC setting or specification determined in step S202 by applying the conditions determined in step S201.
　図７は、本発明の実施の形態におけるＳＰＳ　ＨＡＲＱ－ＡＣＫ送信に使用するリソースを通知する例（２）を示す図である。図７に示されるように、ＲＲＣシグナリングにより設定される、１又は複数のＰＵＣＣＨリソース候補を含む複数のグループセットのうち、ＤＣＩにより１つのグループセットが通知され、ＤＣＩが複数の場合は各フィールドが、ＤＣＩが１つの場合は各ビットが、当該１つのグループのＰＵＣＣＨリソース候補にマッピングされてもよい。図７に示されるように、適用するグループセットは、マッピングを示すフィールドとは異なるフィールドで通知されてもよいし、マッピングを示すフィールドのＬＳＢ又はＭＳＢで通知されてもよいし、他のＤＣＩで通知されてもよい。 FIG. 7 is a diagram showing an example (2) of notifying a resource used for SPS HARQ-ACK transmission in the embodiment of the present invention. As shown in FIG. 7, among a plurality of groupsets including one or a plurality of PUCCH resource candidates set by RRC signaling, one groupset is notified by DCI, and when there are a plurality of DCIs, each field is displayed. , When there is one DCI, each bit may be mapped to the PUCCH resource candidate of the one group. As shown in FIG. 7, the groupset to be applied may be notified in a field different from the field showing the mapping, in the LSB or MSB of the field showing the mapping, or in another DCI. You may be notified.
　延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫを送信するために１つのリソースの候補が通知された場合、当該リソースの候補は延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫを送信するために常に使用されてもよい。延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫを送信するために複数のリソースの候補が通知された場合、後述する方法で複数のリソースの候補の中から使用するリソースを選択する。 If one resource candidate is notified to send a postponed SPS HARQ-ACK, the resource candidate may always be used to send the postponed SPS HARQ-ACK. When multiple resource candidates are notified in order to send the postponed SPS HARQ-ACK, the resource to be used is selected from the multiple resource candidates by the method described later.
　ステップＳ２０３において、決定された候補のうち、いずれのリソースを延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫ送信用のＰＵＣＣＨリソースとして使用するか決定する。ＰＵＣＣＨリソースは、少なくとも一つの順序付け又はＰＵＣＣＨリソース候補に係る所定の条件によって決定されてもよい。例えば、延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫ送信によるＵＬ送信に対する影響を考慮する場合、以下の１）－４）のケースが想定される。 In step S203, it is determined which of the determined candidates is used as the PUCCH resource for the postponed SPS HARQ-ACK transmission. PUCCH resources may be determined by at least one ordering or predetermined conditions relating to PUCCH resource candidates. For example, when considering the effect of postponed SPS HARQ-ACK transmission on UL transmission, the following cases 1) -4) are assumed.
ケース１）延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫのみが、送信するスロット又はサブスロットにある場合（すなわち、延期されていないＳＰＳ　ＨＡＲＱ－ＡＣＫ、動的ＨＡＲＱ－ＡＣＫ、他のＵＣＩは同一スロット又はサブスロットで送信されない場合）。 Case 1) When only the postponed SPS HARQ-ACK is in the transmitting slot or subslot (that is, the undeferred SPS HARQ-ACK, dynamic HARQ-ACK, other UCIs are in the same slot or subslot. If not sent).
　ケース１は、基本的なケースであって、多重が不要であり、延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫのみを対象とするＨＡＲＱ－ＡＣＫコードブックを使用する。ＰＵＣＣＨリソース選択は３ステップで構成され、第１にリソースの候補を順序付けし、第２に要件に基づいて選択し、第３に選択結果に基づいて対応する処理を行う。ケース１では、延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫと同一のスロット又はサブスロットでオーバラップする他のＵＣＩを想定しない。順序付けされたリソースの候補は、延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫを送信するとき、端末２０は、当該順序の先頭のリソースの候補から順に使用するリソースを選択又は選択する処理を実行してもよい。 Case 1 is a basic case, which does not require multiplexing and uses a HARQ-ACK codebook that targets only postponed SPS HARQ-ACK. PUCCH resource selection consists of three steps: first, resource candidates are ordered, second, selection is made based on requirements, and third, corresponding processing is performed based on the selection result. Case 1 does not assume another UCI that overlaps in the same slot or subslot as the postponed SPS HARQ-ACK. When the ordered resource candidates transmit the postponed SPS HARQ-ACK, the terminal 20 may execute a process of selecting or selecting a resource to be used in order from the resource candidate at the head of the order.
　ケース１において、端末２０は、以下１）－６）に示される特定のルールに基づいて、リソースの候補に順序付けを行ってもよい。 In case 1, the terminal 20 may order the resource candidates based on the specific rules shown in 1) -6) below.
１）ＰＵＣＣＨリソース候補のＵＣＩタイプに基づいて順序付けを行ってもよい。例えば、ＳＰＳ　ＨＡＲＱ－ＡＣＫリソースを先頭とし、動的ＨＡＲＱ－ＡＣＫリソース、ＣＳＩリソースの順としてもよい。同一のＵＣＩタイプにおいては、昇順又は降順とするリソースのインデックス又はリソースセットのインデックスに基づいて順序付けを行ってもよいし、リソースの開始シンボル、終了シンボル、長さ、コードレートの少なくとも一つに基づいて順序付けを行ってもよい。ＵＣＩタイプ別の順序は、仕様で定義されてもよいし、ＲＲＣ設定で設定されてもよいし、ＤＣＩにより通知されてもよい。当該ＲＲＣ設定では、ＰＵＣＣＨ－Ｃｏｎｆｉｇに追加される情報要素でＵＣＩのタイプ順が設定されてもよいし、通知する情報要素に基づいてＵＣＩのタイプ順が設定されてもよい。当該ＤＣＩ通知では、ステップＳ２０２におけるＤＣＩに追加されるフィールドでＵＣＩのタイプ順が通知されてもよいし、ステップＳ２０２におけるＤＣＩのフィールドのＬＳＢ又はＭＳＢビットでＵＣＩのタイプ順が通知されてもよい。 1) The ordering may be performed based on the UCI type of the PUCCH resource candidate. For example, the SPS HARQ-ACK resource may be the first, followed by the dynamic HARQ-ACK resource and the CSI resource. In the same UCI type, the ordering may be based on the index of the resource or the index of the resource set in ascending or descending order, or based on at least one of the resource's start symbol, end symbol, length, and code rate. May be ordered. The order by UCI type may be defined in the specifications, set in the RRC settings, or notified by DCI. In the RRC setting, the UCI type order may be set by the information element added to the PUCCH-Config, or the UCI type order may be set based on the information element to be notified. In the DCI notification, the UCI type order may be notified by the field added to the DCI in step S202, or the UCI type order may be notified by the LSB or MSB bit of the DCI field in step S202.
２）ＰＵＣＣＨリソース候補の開始シンボルに基づいて、リソースの候補に順序付けを行ってもよい。例えば、最も早い開始シンボル又は最も遅い開始シンボルを有するリソースの候補を先頭としてもよい。 2) The resource candidates may be ordered based on the start symbol of the PUCCH resource candidate. For example, the candidate resource having the earliest start symbol or the latest start symbol may be the first.
３）ＰＵＣＣＨリソース候補の終了シンボルに基づいて、リソースの候補に順序付けを行ってもよい。例えば、最も早い開始シンボル又は最も遅い終了シンボルを有するリソースの候補を先頭としてもよい。 3) The resource candidates may be ordered based on the end symbol of the PUCCH resource candidate. For example, the candidate resource having the earliest start symbol or the latest end symbol may be the first.
４）ＰＵＣＣＨリソース候補の長さに基づいて、リソースの候補に順序付けを行ってもよい。例えば、最も長い又は最も短い長さのリソースの候補を先頭としてもよい。 4) The resource candidates may be ordered based on the length of the PUCCH resource candidates. For example, the candidate for the longest or shortest resource may be the first.
５）ＰＵＣＣＨリソース候補のコードレートに基づいて、リソースの候補に順序付けを行ってもよい。例えば、最も高い又は最も低いコードレートが適用されるリソースの候補を先頭としてもよい。 5) The resource candidates may be ordered based on the code rate of the PUCCH resource candidates. For example, the candidate resource to which the highest or lowest code rate is applied may be the first.
６）ＰＵＣＣＨリソース候補のインデックスに基づいて、リソースの候補に順序付けを行ってもよい。例えば、リソース又はリソースセットのインデックスを昇順又は降順としてリソースの候補に順序付けを行ってもよい。 6) Resource candidates may be ordered based on the index of PUCCH resource candidates. For example, resource candidates may be ordered in ascending or descending order by indexing a resource or resource set.
　ケース１において、端末２０は、以下要件１）及び要件２）に示される延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫに係る要件を満足する先頭のＰＵＣＣＨリソースを選択してもよい。 In case 1, the terminal 20 may select the first PUCCH resource that satisfies the requirements relating to the postponed SPS HARQ-ACK shown in the following requirements 1) and 2).
要件１）ＴＤＤ衝突に係る要件。無効なシンボルとオーバラップしないことを要件としてもよい。例えば、無効なシンボルとは、セミスタティックなＤＬシンボル、セミスタティックなフレキシブルシンボル、ＳＦＩ通知を考慮したセミスタティックなフレキシブルシンボル（すなわち、ＳＦＩで通知される動的ＤＬシンボル又は動的フレキシブルシンボルあるいはＳＦＩの検出失敗）であってもよい。ここで、ＵＣＩペイロードの範囲は、延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫビット数に対して十分であってもよいし不足していてもよい。あるいは、ＰＲＢの数は、延期されたＳＰＳ　ＨＡＲＱ－ＡＣＫビット数に対して十分であってもよいし不足していてもよい。 Requirement 1) Requirements for TDD collision. It may be a requirement that it does not overlap with invalid symbols. For example, an invalid symbol is a semi-static DL symbol, a semi-static flexible symbol, a semi-static flexible symbol considering SFI notification (that is, a dynamic DL symbol or a dynamic flexible symbol notified by SFI, or an SFI.

It may be postponed, or if the above conditions that allow further delay are not met, the postponed SPS HARQ-ACK transmission may be dropped. Alternatively, the terminal 20 may select the PUCCH resource in the range closest to the payload size of the postponed SPS HARQ-ACK if the requirement 1 is further satisfied if the requirement 1 is applied.
