Description

端末及び通信方法Terminal and communication method
　本発明は、無線通信システムにおける端末及び通信方法に関する。 The present invention relates to a terminal and communication method in a wireless communication system.
　３ＧＰＰ（3rd Generation Partnership Project）では、システム容量の更なる大容量化、データ伝送速度の更なる高速化、無線区間における更なる低遅延化等を実現するために、５ＧあるいはＮＲ（New Radio）と呼ばれる無線通信方式（以下、当該無線通信方式を「ＮＲ」という。）の検討が進んでいる。５Ｇでは、１０Ｇｂｐｓ以上のスループットを実現しつつ無線区間の遅延を１ｍｓ以下にするという要求条件を満たすために、様々な無線技術及びネットワークアーキテクチャの検討が行われている（例えば非特許文献１）。 In the 3GPP (3rd Generation Partnership Project), 5G or NR (New Radio) and NR (New Radio) are being used in order to further increase the system capacity, further increase the data transmission speed, and further reduce the delay in the wireless section. A radio communication system called "NR" (the radio communication system is hereinafter referred to as "NR") is under study. In 5G, various radio technologies and network architectures are being studied in order to meet the requirements of realizing a throughput of 10 Gbps or more and keeping the delay in the radio section to 1 ms or less (for example, Non-Patent Document 1).
　さらに、３ＧＰＰ標準化において、ＵＲＬＬＣ（Ultra-Reliable and Low Latency Communications）技術の拡張に関して、ＰＵＣＣＨ（Physical Uplink Control Channel）キャリアスイッチング（carrier switching）が検討されている。ＰＵＣＣＨキャリアスイッチングは、ＴＤＤ（Time Division Duplex）方式において、ＨＡＲＱ－ＡＣＫ（Hybrid Automatic Repeat reQuest-ACKnowledgement)フィードバックのレイテンシを削減する方法として検討されている（例えば非特許文献２）。 Furthermore, in the 3GPP standardization, PUCCH (Physical Uplink Control Channel) carrier switching is being considered for extension of URLLC (Ultra-Reliable and Low Latency Communications) technology. PUCCH carrier switching is being studied as a method of reducing HARQ-ACK (Hybrid Automatic Repeat reQuest-ACKnowledgement) feedback latency in the TDD (Time Division Duplex) scheme (eg, Non-Patent Document 2).
　例えば、ＨＡＲＱ－ＡＣＫを送信するスロットがダウンリンクに割り当てられている場合、ＰＵＣＣＨキャリアスイッチングが実行される場合がある。一方、ＨＡＲＱ－ＡＣＫを送信するスロットがダウンリンクに割り当てられている場合であっても、端末内でＵＣＩ（Uplink Control Information）多重が実行可能であった場合、ＰＵＣＣＨキャリアスイッチングを実行せずに、当該端末はＨＡＲＱ－ＡＣＫを送信することができる。すなわち、処理動作の実行順によって、ＵＣＩが送信されるチャネルが異なることがあった。 For example, PUCCH carrier switching may be performed if a slot for transmitting HARQ-ACK is assigned to the downlink. On the other hand, even if the slot for transmitting HARQ-ACK is assigned to the downlink, if UCI (Uplink Control Information) multiplexing can be executed in the terminal, without executing PUCCH carrier switching, The terminal may send HARQ-ACK. In other words, the channel through which the UCI is transmitted may differ depending on the execution order of the processing operations.
　本発明は上記の点に鑑みてなされたものであり、無線通信システムにおいて、ＵＣＩ（Uplink Control Information）を送信する手順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 of the present invention is to determine a procedure for transmitting UCI (Uplink Control Information) in a wireless communication system.
　開示の技術によれば、上り制御情報を運ぶチャネルに適用するキャリアスイッチングと、上り制御情報を運ぶチャネルと上り制御情報を運ぶチャネルとに適用する多重化のうち、少なくとも一つを実行する制御部と、前記キャリアスイッチング及び前記多重化の少なくとも一つが適用された上り制御情報を運ぶチャネルを送信する送信部とを有し、前記制御部は、下り制御情報によるダイナミックキャリアスイッチングと、予め規定されたセミスタティックキャリアスイッチングのいずれかを上り制御情報を運ぶチャネルに適用する端末が提供される。 According to the disclosed technique, a control unit that performs at least one of carrier switching applied to a channel carrying uplink control information and multiplexing applied to a channel carrying uplink control information and a channel carrying uplink control information and a transmitting unit that transmits a channel carrying uplink control information to which at least one of the carrier switching and the multiplexing is applied, wherein the control unit performs dynamic carrier switching according to downlink control information, and a predefined A terminal is provided that applies any of semi-static carrier switching to channels carrying uplink control information.
　開示の技術によれば、無線通信システムにおいて、ＵＣＩ（Uplink Control Information）を送信する手順を決定することができる。 According to the disclosed technology, it is possible to determine a procedure for transmitting UCI (Uplink Control Information) in a wireless communication system.

In addition, the embodiment described below is an example, and the embodiment to which the present invention is applied is not limited to the following embodiment.

The existing technology is, for example, existing NR or LTE, but is not limited to existing NR or LTE.
　図１は、本発明の実施の形態における無線通信システムの例（１）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 example (1) of a wireless communication system according to an embodiment of the present invention. A wireless communication system according to an embodiment of the present invention includes a base station 10 and terminals 20, as shown in FIG. Although one base station 10 and one terminal 20 are shown in FIG. 1, this is an example and there may be more than one.
　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. A physical resource of a radio signal is defined in the time domain and the frequency domain. The time domain may be defined by the number of OFDM symbols, and the frequency domain may be defined by the number of subcarriers or resource blocks. Also, a TTI (Transmission Time Interval) in the time domain may be a slot, or a TTI may be a subframe.
　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ＰＣｅｌｌ（プライマリセル）と１以上のＳＣｅｌｌ（セカンダリセル）が使用される。 The base station 10 can perform carrier aggregation in which multiple cells (multiple CCs (component carriers)) are bundled and communicated with the terminal 20 . In carrier aggregation, one PCell (primary cell) and one or more SCells (secondary cells) 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, etc. to the terminal 20. Synchronization signals are, for example, NR-PSS and NR-SSS. System information is transmitted, for example, on NR-PBCH or PDSCH, and is also called broadcast information. As shown in FIG. 1, the base station 10 transmits control signals or data to the terminal 20 on DL (Downlink) and receives control signals or data from the terminal 20 on UL (Uplink). Here, what is transmitted on control channels such as PUCCH and PDCCH is called a control signal, and what is transmitted on a shared channel such as PUSCH and PDSCH is called data. 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 with a wireless communication function, such as a smartphone, mobile phone, tablet, wearable terminal, or M2M (Machine-to-Machine) communication module. As shown in FIG. 1 , the terminal 20 receives control signals or data from the base station 10 on the DL and transmits control signals or data to the base station 10 on the UL, thereby performing various functions provided by the wireless communication system. Use communication services. Note that the terminal 20 may be called UE, and the base station 10 may be called gNB.
　図２は、本発明の実施の形態における無線通信システムの例（２）を説明するための図である。図２は、デュアルコネクティビティ（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に示されるとおり、マスタノード（ＭＮ：Master Node）となる基地局１０Ａと、セカンダリノード（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３０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 is a diagram for explaining example (2) of the wireless communication system according to the embodiment of the present invention. FIG. 2 shows a configuration example of a radio communication system when dual connectivity (DC) is performed. As shown in FIG. 2, a base station 10A serving as a master node (MN: Master Node) and a base station 10B serving as a secondary node (SN: Secondary Node) are provided. The base station 10A and the base station 10B are connected to the core network 30 respectively. Terminal 20 can communicate with both base station 10A and 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マスタセルグループ（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セカンダリセルグループ（ＳＣＧ：Secondary Cell Group）と呼ぶ。また、デュアルコネクティビティにおいて、ＭＣＧは１つのＰＣｅｌｌと０以上のＳＣｅｌｌから構成され、ＳＣＧは１つのＰＳＣｅｌｌ（Primary SCG Cell）と０以上のＳＣｅｌｌから構成される。 A cell group provided by the base station 10A, which is the MN, is called a master cell group (MCG), and a cell group provided by the base station 10B, which is the SN, is called a secondary cell group (SCG). call. In dual connectivity, an MCG is composed of one PCell and 0 or more SCells, and an SCG is composed of one PSCell (Primary SCG Cell) and 0 or more SCells.
　なお、デュアルコネクティビティは２つの通信規格を利用した通信方法であってもよく、どのような通信規格が組み合わされてもよい。例えば、当該組み合わせは、ＮＲと６Ｇ規格、ＬＴＥと６Ｇ規格のいずれでもよい。また、デュアルコネクティビティは３以上の通信規格を利用した通信方法であってもよく、デュアルコネクティビティとは異なる他の名称で呼ばれてもよい。 Note that dual connectivity may be a communication method using two communication standards, and any communication standards may be combined. For example, the combination may be either NR and 6G standard or LTE and 6G standard. Also, dual connectivity may be a communication method using three or more communication standards, and may be called by other names different from dual connectivity.
　本実施の形態における処理動作は、図１に示されるシステム構成で実行されてもよいし、図２に示されるシステム構成で実行されてもよいし、これら以外のシステム構成で実行されてもよい。 The processing operations in the present embodiment may be executed in the system configuration shown in FIG. 1, may be executed in the system configuration shown in FIG. 2, or may be executed in a system configuration other than these. .
　３ＧＰＰ標準化において、強化されたＩｏＴ（Internet of Things）及びＵＲＬＬＣ（Ultra-reliable and low latency communication）をＮＲでサポートすることが検討されている。さらに、ＵＲＬＬＣの要件に対応するため、ＨＡＲＱ－ＡＣＫのフィードバックの強化が検討されている。 　In 3GPP standardization, support for enhanced IoT (Internet of Things) and URLLC (Ultra-reliable and low latency communication) in NR is being considered. Furthermore, enhancement of HARQ-ACK feedback is being considered to meet URLLC requirements.
　図３は、ＰＵＣＣＨキャリアスイッチングの例（１）を示す図である。ＨＡＲＱフィードバックのため、ＰＵＣＣＨキャリアスイッチングが検討されている。図３に示されるように、ＰＵＣＣＨが送信されるセル１において、タイミングＴ１のＰＤＳＣＨに対応するＨＡＲＱ－ＡＣＫが、Ｋ１値未満のタイミングＴ２のＰＵＣＣＨで送信されるとき、セル１におけるタイミングＴ２はＤＬであるため送信することができず、セル１がＵＬとなるタイミングＴ３ではＫ１値を超える。そこで、タイミングＴ２がＵＬであるセル２において、ＰＵＣＣＨが送信される。なお、Ｋ１値は、ＰＤＳＣＨからＨＡＲＱフィードバックまでのタイミングを示すパラメータであってもよい。 FIG. 3 is a diagram showing an example (1) of PUCCH carrier switching. PUCCH carrier switching is being considered for HARQ feedback. As shown in FIG. 3, in cell 1 where PUCCH is transmitted, when HARQ-ACK corresponding to PDSCH at timing T1 is transmitted at PUCCH at timing T2 less than the K1 value, timing T2 in cell 1 is DL Therefore, the K1 value is exceeded at timing T3 when cell 1 becomes UL. Therefore, PUCCH is transmitted in cell 2 whose timing T2 is UL. Note that the K1 value may be a parameter indicating the timing from PDSCH to HARQ feedback.
　ＨＡＲＱ－ＡＣＫ含むＵＣＩ（Uplink Control Information）のＵＥ内多重（intra-UE multiplexing）は、セミスタティックＤＬシンボル、ＳＳＢ（SS/PBCH block）シンボル及びＳＦＩ（Slot Format Indication）と衝突することに起因するＵＬチャネルのキャンセル以前に実行される。 Intra-UE multiplexing of UCI (Uplink Control Information) including HARQ-ACK is semi-static DL symbol, SSB (SS / PBCH block) symbol and UL due to collision with SFI (Slot Format Indication) Executed before channel cancellation.
　ここで、ＰＵＣＣＨキャリアスイッチングがセミスタティック設定に基づいてサポートされ、かつ端末２０が無効なシンボルとの衝突を条件とする所定のルールに基づいてＰＵＣＣＨキャリアを決定するとき、ＰＵＣＣＨキャリアスイッチングとＵＥ内多重の実行順がＵＬ送信結果に影響を及ぼす。 Here, PUCCH carrier switching and intra-UE multiplexing when PUCCH carrier switching is supported based on semi-static configuration and terminal 20 determines the PUCCH carrier based on a predetermined rule conditional on collision with invalid symbols. order of execution affects the UL transmission result.
　図４は、ＰＵＣＣＨキャリアスイッチングの例（２）を示す図である。仮に、ＵＥ内多重がＰＵＣＣＨキャリアスイッチングよりも先に実行される場合、図４の例では、ＰＵＳＣＨセルにおけるＤＧ（Dynamic grant）－ＰＵＳＣＨにおいて、ＨＡＲＱ－ＡＣＫが送信される。一方、ＰＵＣＣＨキャリアスイッチングがＵＥ内多重よりも先に実行される場合、図４の例では、ＰＵＣＣＨ候補セルのＰＵＣＣＨにおいてＨＡＲＱ－ＡＣＫが送信されると決定され、さらにＵＥ内多重により、ＰＵＳＣＨセルにおけるＣＧ（Configured grant）－ＰＵＳＣＨにおいて、ＨＡＲＱ－ＡＣＫが送信される。 FIG. 4 is a diagram showing an example (2) of PUCCH carrier switching. If intra-UE multiplexing is performed prior to PUCCH carrier switching, HARQ-ACK is transmitted in DG (Dynamic grant)-PUSCH in the PUSCH cell in the example of FIG. On the other hand, when PUCCH carrier switching is performed before intra-UE multiplexing, in the example of FIG. 4, it is determined that HARQ-ACK is transmitted in PUCCH of the PUCCH candidate cell, and further intra-UE multiplexing in the PUSCH cell HARQ-ACK is transmitted on CG (Configured grant)-PUSCH.

Note that PUCCHs to be multiplexed may be assigned to the same carrier or may be assigned to different carriers.
１）１ＰＵＣＣＨのリソースが、他のＰＵＣＣＨのリソースにオーバラップするとき。
２）１ＰＵＣＣＨを含むスロットが、他のＰＵＣＣＨを含むスロットにオーバラップするとき。又は２つのＰＵＣＣＨが同一スロットに含まれるとき。
３）１ＰＵＣＣＨのリソースが、他のＰＵＣＣＨを含むスロットにオーバラップするとき。 1) When one PUCCH resource overlaps another PUCCH resource.
2) When a slot containing one PUCCH overlaps a slot containing another PUCCH. Or when two PUCCHs are included in the same slot.
3) When one PUCCH resource overlaps a slot containing another PUCCH.
　上記１）－３）のいずれが適用されるかは、ＵＣＩタイプにより異なってもよい。例えば、ダイナミックＨＡＲＱ－ＡＣＫとＳＰＳ　ＨＡＲＱ－ＡＣＫの多重化の場合、上記２）が適用されてもよい。また、例えば、ＨＡＲＱ－ＡＣＫとＣＳＩの多重の場合、上記１）が適用されてもよい。なお、スロットは、各キャリアのＳＣＳに基づいて定義される。 Which of the above 1)-3) is applied may differ depending on the UCI type. For example, in the case of multiplexing dynamic HARQ-ACK and SPS HARQ-ACK, 2) above may be applied. Also, for example, in the case of multiplexing HARQ-ACK and CSI, 1) above may be applied. A slot is defined based on the SCS of each carrier.
　また、図５、図６、図７及び図８に示される動作において、以下１）－４）に示されるＵＣＩ多重化に係るルールが適用されてもよい。 Also, in the operations shown in FIGS. 5, 6, 7 and 8, the rules related to UCI multiplexing shown in 1)-4) below may be applied.
１）２つのＰＵＣＣＨが同一のキャリアに配置されている場合、多重化後のＰＵＣＣＨは当該同一のキャリアに配置されてもよい。例えば、ダイナミックＨＡＲＱ－ＡＣＫ及びＳＰＳ　ＨＡＲＱ－ＡＣＫが同一のキャリアＣＣ＃０にある場合、多重化後のＰＵＣＣＨは、ダイナミックＨＡＲＱ－ＡＣＫのＰＵＣＣＨリソースであってもよい。 1) When two PUCCHs are mapped to the same carrier, the multiplexed PUCCH may be mapped to the same carrier. For example, if dynamic HARQ-ACK and SPS HARQ-ACK are on the same carrier CC#0, the PUCCH after multiplexing may be the PUCCH resource for dynamic HARQ-ACK.
２）２つのＰＵＣＣＨが同一のキャリアに配置されている場合、多重化後のＰＵＣＣＨは当該同一のキャリアに配置されてもよい。例えば、ＳＰＳ　ＨＡＲＱ－ＡＣＫ及びＣＳＩが同一のキャリアＣＣ＃０にある場合、多重化後のＰＵＣＣＨは、ＣＳＩのＰＵＣＣＨリソースであってもよい。 2) When two PUCCHs are mapped to the same carrier, the multiplexed PUCCH may be mapped to the same carrier. For example, when SPS HARQ-ACK and CSI are on the same carrier CC#0, the PUCCH after multiplexing may be the PUCCH resource of CSI.
３）２つのＰＵＣＣＨが異なるキャリアに配置されている場合、多重化後のＰＵＣＣＨは、選択されたＵＣＩタイプと同じＵＣＩタイプのＰＵＣＣＨが配置されるキャリアに配置されてもよい。例えば、ダイナミックＨＡＲＱ－ＡＣＫがＣＣ＃１、ＳＰＳ　ＨＡＲＱ－ＡＣＫがＣＣ＃２に配置されている場合、多重化後のＰＵＣＣＨは、ダイナミックＨＡＲＱ－ＡＣＫ配置されるＣＣ＃１に配置されてもよい。 3) When two PUCCHs are mapped to different carriers, the multiplexed PUCCH may be mapped to a carrier on which PUCCHs of the same UCI type as the selected UCI type are mapped. For example, if dynamic HARQ-ACK is mapped to CC#1 and SPS HARQ-ACK is mapped to CC#2, PUCCH after multiplexing may be mapped to CC#1, which is mapped to dynamic HARQ-ACK.
４）２つのＰＵＣＣＨが異なるキャリアに配置されている場合、多重化後のＰＵＣＣＨは、選択されたＵＣＩタイプと同じＵＣＩタイプのＰＵＣＣＨが配置されるキャリアに配置されてもよい。例えば、ＳＰＳ　ＨＡＲＱ－ＡＣＫがＣＣ＃２、ＣＳＩがＣＣ＃３に配置されている場合、多重化後のＰＵＣＣＨは、ＳＰＳ　ＨＡＲＱ－ＡＣＫが配置されるＣＣ＃２に配置されてもよい。 4) When two PUCCHs are mapped to different carriers, the multiplexed PUCCH may be mapped to a carrier on which PUCCHs of the same UCI type as the selected UCI type are mapped. For example, if SPS HARQ-ACK is assigned to CC#2 and CSI is assigned to CC#3, PUCCH after multiplexing may be assigned to CC#2 to which SPS HARQ-ACK is assigned.
　また、図５、図６、図７及び図８に示される動作において、以下１）－３）に示されるようにダイナミック又はセミスタティックなＰＵＣＣＨキャリアスイッチングがあるＰＵＣＣＨに適用されてもよい。 Also, in the operations shown in FIGS. 5, 6, 7 and 8, dynamic or semi-static PUCCH carrier switching may be applied to PUCCH as shown in 1)-3) below.
１）対象ＰＵＣＣＨが多重化されていないＰＵＣＣＨ（ＵＣＩタイプが１つ）である場合、ＵＣＩタイプに基づいてＰＵＣＣＨキャリアスイッチングが適用されてもよい。例えば、ダイナミックＨＡＲＱ－ＡＣＫのＰＵＣＣＨである場合、ダイナミックＰＵＣＣＨキャリアスイッチングが適用されてもよい。例えばＳＰＳ　ＨＡＲＱ－ＡＣＫのＰＵＣＣＨである場合、当該ＳＰＳ　ＨＡＲＱ－ＡＣＫにセミスタティックＰＵＣＣＨキャリアスイッチングが適用可能である場合、セミスタティックＰＵＣＣＨキャリアスイッチングが適用されてもよい。例えば、ＣＳＩのＰＵＣＣＨである場合、当該ＣＳＩにセミスタティックＰＵＣＣＨキャリアスイッチングが適用可能でない場合、ＰＵＣＣＨキャリアスイッチングは当該ＣＳＩのＰＵＣＣＨに適用されなくてもよい。 1) If the target PUCCH is a non-multiplexed PUCCH (one UCI type), PUCCH carrier switching may be applied based on the UCI type. For example, in the case of dynamic HARQ-ACK PUCCH, dynamic PUCCH carrier switching may be applied. For example, in the case of SPS HARQ-ACK PUCCH, if semi-static PUCCH carrier switching is applicable to the SPS HARQ-ACK, semi-static PUCCH carrier switching may be applied. For example, in the case of a PUCCH of CSI, PUCCH carrier switching may not be applied to the PUCCH of that CSI if semi-static PUCCH carrier switching is not applicable to that CSI.
２）対象ＰＵＣＣＨが多重化後のＰＵＣＣＨである場合、多重化後のＰＵＣＣＨリソースのＵＣＩタイプに基づいてＰＵＣＣＨキャリアスイッチングが適用されてもよい。例えば、ダイナミックＨＡＲＱ－ＡＣＫとＳＰＳ　ＨＡＲＱ－ＡＣＫを多重化後のＰＵＣＣＨが、ダイナミックＨＡＲＱ－ＡＣＫが設定されるＰＵＣＣＨリソースで送信される場合、ダイナミックＰＵＣＣＨキャリアスイッチングが適用されてもよい。例えば、ＳＰＳ　ＨＡＲＱ－ＡＣＫとＣＳＩを多重化後のＰＵＣＣＨが、ＣＳＩが設定されるＰＵＣＣＨリソースで送信される場合、かつセミスタティックＰＵＣＣＨキャリアスイッチングがＳＰＳ　ＨＡＲＱ－ＡＣＫに適用可能である場合、ＰＵＣＣＨキャリアスイッチングは多重化後のＰＵＣＣＨに適用されなくてもよい。 2) If the target PUCCH is the multiplexed PUCCH, PUCCH carrier switching may be applied based on the UCI type of the multiplexed PUCCH resource. For example, dynamic PUCCH carrier switching may be applied when PUCCH after multiplexing dynamic HARQ-ACK and SPS HARQ-ACK is transmitted on PUCCH resources configured with dynamic HARQ-ACK. For example, when PUCCH after multiplexing SPS HARQ-ACK and CSI is transmitted on PUCCH resources in which CSI is configured, and when semi-static PUCCH carrier switching is applicable to SPS HARQ-ACK, PUCCH carrier switching may not be applied to PUCCH after multiplexing.
３）対象ＰＵＣＣＨが多重化後のＰＵＣＣＨである場合、多重化後のＰＵＣＣＨに含まれるＵＣＩタイプに基づいてＰＵＣＣＨキャリアスイッチングが適用されてもよい。例えば、多重化後のＰＵＣＣＨが、ダイナミックＨＡＲＱ－ＡＣＫを含む場合、ダイナミックＰＵＣＣＨキャリアスイッチングが適用されてもよい。例えば、多重化後のＰＵＣＣＨが、ダイナミックＨＡＲＱ－ＡＣＫを含まず、セミスタティックＰＵＣＣＨキャリアスイッチングが適用可能なＵＣＩタイプを含む場合、セミスタティックＰＵＣＣＨキャリアスイッチングが適用されてもよい。多重化後のＰＵＣＣＨがダイナミックＨＡＲＱ－ＡＣＫを含む場合又はダイナミックＨＡＲＱ－ＡＣＫを含まず、セミスタティックＰＵＣＣＨキャリアスイッチングが適用可能なＵＣＩタイプを含む場合以外の場合、ＰＵＣＣＨキャリアスイッチングは適用されなくてもよい。 3) If the target PUCCH is the multiplexed PUCCH, PUCCH carrier switching may be applied based on the UCI type included in the multiplexed PUCCH. For example, if the PUCCH after multiplexing contains dynamic HARQ-ACK, dynamic PUCCH carrier switching may be applied. Semi-static PUCCH carrier switching may be applied, for example, if the PUCCH after multiplexing does not include dynamic HARQ-ACK and includes UCI types for which semi-static PUCCH carrier switching is applicable. PUCCH carrier switching may not be applied unless multiplexed PUCCH includes dynamic HARQ-ACK or does not include dynamic HARQ-ACK and includes UCI types for which semi-static PUCCH carrier switching is applicable. .

　上述の実施例により、端末２０において、１又は複数のＵＣＩを送信するとき、ＰＵＣＣＨキャリアスイッチング及び多重化を適切な順序で適用することで、ＵＣＩを送信するリソースを決定することができる。 According to the above embodiment, when transmitting one or more UCIs in the terminal 20, it is possible to determine resources for transmitting the UCIs by applying PUCCH carrier switching and multiplexing in an appropriate order.

Each frame or frames in the time domain may be referred to as a subframe. A subframe may also consist of one or more slots in the time domain. A subframe may be of a fixed length of time (eg, 1 ms) independent of numerology.
　ニューメロロジは、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。ニューメロロジは、例えば、サブキャリア間隔（ＳＣＳ：SubCarrier　Spacing）、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（ＴＴＩ：Transmission　Time　Interval）、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。 A numerology may be a communication parameter that applies to the transmission and/or reception of a signal or channel.

PDSCH (or PUSCH) transmitted using minislots may be referred to as PDSCH (or 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。 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サブフレームは送信時間間隔（ＴＴＩ：Transmission　Time　Interval）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 Transmission Time Interval (TTI), a plurality of consecutive subframes may be called a TTI, and one slot or one minislot may be called a TTI. may That is, at least one of the subframe and TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (eg, 1-13 symbols), or a period longer than 1 ms may be Note that the unit representing the TTI may be called a slot, mini-slot, or the like instead of a subframe.
　ここで、ＴＴＩは、例えば、無線通信におけるスケジューリングの最小時間単位のことをいう。例えば、ＬＴＥシステムでは、基地局が各端末２０に対して、無線リソース（各端末２０において使用することが可能な周波数帯域幅、送信電力など）を、ＴＴＩ単位で割り当てるスケジューリングを行う。なお、ＴＴＩの定義はこれに限られない。 Here, TTI refers to, for example, the minimum scheduling time unit in wireless communication. For example, in the LTE system, the base station performs scheduling to allocate radio resources (frequency bandwidth, transmission power, etc. that can be used by each terminal 20) to each terminal 20 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.
　なお、１スロット又は１ミニスロットがＴＴＩと呼ばれる場合、１以上のＴＴＩ（すなわち、１以上のスロット又は１以上のミニスロット）が、スケジューリングの最小時間単位となってもよい。また、当該スケジューリングの最小時間単位を構成するスロット数（ミニスロット数）は制御されてもよい。 When one slot or one minislot is called a TTI, one or more TTIs (that is, one or more slots or one or more minislots) may be the minimum scheduling time unit. Also, the number of slots (the number of mini-slots) constituting the minimum time unit of the scheduling may be controlled.
　１ｍｓの時間長を有するＴＴＩは、通常ＴＴＩ（ＬＴＥ　Ｒｅｌ．８－１２におけるＴＴＩ）、ノーマルＴＴＩ、ロングＴＴＩ、通常サブフレーム、ノーマルサブフレーム、ロングサブフレーム、スロットなどと呼ばれてもよい。通常ＴＴＩより短いＴＴＩは、短縮ＴＴＩ、ショートＴＴＩ、部分ＴＴＩ（partial又はfractional　TTI）、短縮サブフレーム、ショートサブフレーム、ミニスロット、サブスロット、スロットなどと呼ばれてもよい。 A TTI having a time length of 1 ms may be called a normal TTI (TTI in LTE Rel. 8-12), normal TTI, long TTI, normal subframe, normal subframe, long subframe, slot, or the like. 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.
　リソースブロック（ＲＢ）は、時間領域及び周波数領域のリソース割当単位であり、周波数領域において、１つ又は複数個の連続した副搬送波（subcarrier）を含んでもよい。ＲＢに含まれるサブキャリアの数は、ニューメロロジに関わらず同じであってもよく、例えば１２であってもよい。ＲＢに含まれるサブキャリアの数は、ニューメロロジに基づいて決定されてもよい。 A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in the RB may be the same regardless of the numerology, and may be 12, for example. The number of subcarriers included in an RB may be determined based on numerology.
　また、ＲＢの時間領域は、１つ又は複数個のシンボルを含んでもよく、１スロット、１ミニスロット、１サブフレーム、又は１ＴＴＩの長さであってもよい。１ＴＴＩ、１サブフレームなどは、それぞれ１つ又は複数のリソースブロックで構成されてもよい。 Also, the time domain of an RB may include one or more symbols and may be 1 slot, 1 minislot, 1 subframe, or 1 TTI long. One TTI, one subframe, etc. may each consist of one or more resource blocks.
　なお、１つ又は複数のＲＢは、物理リソースブロック（ＰＲＢ：Physical　RB）、サブキャリアグループ（ＳＣＧ：Sub-Carrier　Group）、リソースエレメントグループ（ＲＥＧ：Resource　Element　Group）、ＰＲＢペア、ＲＢペアなどと呼ばれてもよい。 One or more RBs are physical resource blocks (PRBs), sub-carrier groups (SCGs), resource element groups (REGs), PRB pairs, RB pairs, etc. may be called.
　また、リソースブロックは、１つ又は複数のリソースエレメント（ＲＥ：Resource　Element）によって構成されてもよい。例えば、１ＲＥは、１サブキャリア及び１シンボルの無線リソース領域であってもよい。 Also, a resource block may be composed of one or more resource elements (RE: Resource Element). For example, 1 RE may be a radio resource region of 1 subcarrier and 1 symbol.
　帯域幅部分（ＢＷＰ：Bandwidth　Part）（部分帯域幅などと呼ばれてもよい）は、あるキャリアにおいて、あるニューメロロジ用の連続する共通ＲＢ（common　resource　blocks）のサブセットのことを表してもよい。ここで、共通ＲＢは、当該キャリアの共通参照ポイントを基準としたＲＢのインデックスによって特定されてもよい。ＰＲＢは、あるＢＷＰで定義され、当該ＢＷＰ内で番号付けされてもよい。 A bandwidth part (BWP) (which may also be called a bandwidth part) may represent a subset of contiguous common resource blocks (RBs) for a certain numerology on a certain carrier. Here, the common RB may be identified by an RB index based on the common reference point of the carrier. PRBs may be defined in a BWP and numbered within that BWP.
　ＢＷＰには、ＵＬ用のＢＷＰ（ＵＬ　ＢＷＰ）と、ＤＬ用のＢＷＰ（ＤＬ　ＢＷＰ）とが含まれてもよい。端末２０に対して、１キャリア内に１つ又は複数のＢＷＰが設定されてもよい。 The BWP may include a BWP for UL (UL BWP) and a BWP for DL (DL BWP). One or more BWPs may be configured for terminal 20 within one carrier.
　設定されたＢＷＰの少なくとも１つがアクティブであってもよく、端末２０は、アクティブなＢＷＰの外で所定の信号／チャネルを送受信することを想定しなくてもよい。なお、本開示における「セル」、「キャリア」などは、「ＢＷＰ」で読み替えられてもよい。 At least one of the configured BWPs may be active, and the terminal 20 may not expect to transmit or receive a given signal/channel outside the active BWP. Note that "cell", "carrier", etc. in the present disclosure may be read as "BWP".
