　3rd Generation Partnership Project（3GPP）は、5th generation mobile communication system（5G、New Radio（NR）又はNext Generation（NG）とも呼ばれる）を仕様化し、さらに、Beyond 5G、5G Evolution或いは6Gと呼ばれる次世代の仕様化も進めている。 The 3rd Generation Partnership Project (3GPP) has specified the 5th generation mobile communication system (also called 5G, New Radio (NR) or Next Generation (NG)), and the next generation specification called Beyond 5G, 5G Evolution or 6G We are also proceeding with

The gist is to comprise a communication unit that receives an information element from a network, and a control unit that controls multiplexing of the uplink control information to the uplink shared channel based on the information element.
　本開示は、基地局であって、第１優先度の上りリンク共有チャネルに対する第２優先度の上りリンク制御情報の多重に関する有効化及び無効化の少なくともいずれか１つを明示的又は暗黙的に示す情報要素を端末に送信する通信部と、前記情報要素に基づいて、前記上りリンク共有チャネルを介した上りリンク信号の受信を想定する制御部と、を備える、ことを要旨とする。 The present disclosure is a base station, explicitly or implicitly at least one of enabling and disabling of multiplexing of uplink control information of the second priority for the uplink shared channel of the first priority and a control unit that assumes reception of an uplink signal via the uplink shared channel based on the information element.

　以下、実施形態を図面に基づいて説明する。なお、同一の機能や構成には、同一又は類似の符号を付して、その説明を適宜省略する。 Hereinafter, embodiments will be described based on the drawings. Note that the same or similar reference numerals are given to the same functions and configurations, and the description thereof will be omitted as appropriate.
　［実施形態］
　（１）無線通信システムの全体概略構成
　図１は、実施形態に係る無線通信システム10の全体概略構成図である。無線通信システム10は、5G New Radio（NR）に従った無線通信システムであり、Next Generation-Radio Access Network 20（以下、NG-RAN20、及び端末200（以下、UE200）を含む。 [Embodiment]
(1) Overall Schematic Configuration of Radio Communication System FIG. 1 is an overall schematic configuration diagram of a radio communication system 10 according to an embodiment. The radio communication system 10 is a radio communication system according to 5G New Radio (NR), and includes a Next Generation-Radio Access Network 20 (hereinafter NG-RAN 20 and a terminal 200 (hereinafter UE 200).
　なお、無線通信システム10は、Beyond 5G、5G Evolution或いは6Gと呼ばれる方式に従った無線通信システムでもよい。 Note that the wireless communication system 10 may be a wireless communication system according to a system called Beyond 5G, 5G Evolution, or 6G.
　NG-RAN20は、無線基地局100A（以下、gNB100A）及び無線基地局100B（以下、gNB100B）を含む。なお、gNB及びUEの数を含む無線通信システム10の具体的な構成は、図１に示した例に限定されない。 NG-RAN 20 includes a radio base station 100A (hereinafter gNB100A) and a radio base station 100B (hereinafter gNB100B). Note that the specific configuration of the radio communication system 10 including the number of gNBs and UEs is not limited to the example shown in FIG.
　NG-RAN20は、実際には複数のNG-RAN Node、具体的には、gNB（又はng-eNB）を含み、5Gに従ったコアネットワーク（5GC、不図示）と接続される。なお、NG-RAN20及び5GCは、単に「ネットワーク」と表現されてもよい。 NG-RAN 20 actually includes multiple NG-RAN Nodes, specifically gNBs (or ng-eNBs), and is connected to a 5G-compliant core network (5GC, not shown). Note that NG-RAN 20 and 5GC may simply be referred to as a "network".
　gNB100A及びgNB100Bは、5Gに従った無線基地局であり、UE200と5Gに従った無線通信を実行する。gNB100A、gNB100B及びUE200は、複数のアンテナ素子から送信される無線信号を制御することによって、より指向性の高いビームBMを生成するMassive MIMO（Multiple-Input Multiple-Output）、複数のコンポーネントキャリア（CC）を束ねて用いるキャリアアグリゲーション（CA）、及びUEと２つのNG-RAN Nodeそれぞれとの間において同時２以上のトランスポートブロックに通信を行うデュアルコネクティビティ（DC）などに対応することができる。 gNB100A and gNB100B are 5G-compliant radio base stations and perform 5G-compliant radio communication with UE200. gNB100A, gNB100B and UE200 generate BM beams with higher directivity by controlling radio signals transmitted from multiple antenna elements Massive MIMO (Multiple-Input Multiple-Output), multiple component carriers (CC ), and dual connectivity (DC) that simultaneously communicates with two or more transport blocks between the UE and each of the two NG-RAN Nodes.
　また、無線通信システム10は、複数の周波数レンジ（FR）に対応する。図２は、無線通信システム10において用いられる周波数レンジを示す。 Also, the wireless communication system 10 supports multiple frequency ranges (FR). FIG. 2 shows the frequency ranges used in wireless communication system 10. As shown in FIG.
　図２に示すように、無線通信システム10は、FR1及びFR2に対応する。各FRの周波数帯は、次のとおりである。 As shown in FIG. 2, the wireless communication system 10 supports FR1 and FR2. The frequency bands of each FR are as follows.
　・FR1：410 MHz～7.125 GHz
　・FR2：24.25 GHz～52.6 GHz
　FR1では、15, 30又は60kHzのSub-Carrier Spacing（SCS）が用いられ、5～100MHzの帯域幅（BW）が用いられてもよい。FR2は、FR1よりも高周波数であり、60,又は120kHz（240kHzが含まれてもよい）のSCSが用いられ、50～400MHzの帯域幅（BW）が用いられてもよい。 ・FR1: 410MHz to 7.125GHz
・FR2: 24.25 GHz to 52.6 GHz
In FR1, a Sub-Carrier Spacing (SCS) of 15, 30 or 60 kHz may be used and a bandwidth (BW) of 5-100 MHz may be used. FR2 is higher frequency than FR1 and may use an SCS of 60 or 120 kHz (240 kHz may be included) and a bandwidth (BW) of 50-400 MHz.
　なお、SCSは、numerologyと解釈されてもよい。numerologyは、3GPP TS38.300において定義されており、周波数ドメインにおける一つのサブキャリア間隔と対応する。 It should be noted that SCS may be interpreted as numerology. numerology is defined in 3GPP TS38.300 and corresponds to one subcarrier spacing in the frequency domain.
　さらに、無線通信システム10は、FR2の周波数帯よりも高周波数帯にも対応する。具体的には、無線通信システム10は、52.6GHzを超え、71GHzまたは114.25GHzまでの周波数帯に対応する。このような高周波数帯は、便宜上「FR2x」と呼ばれてもよい。 Furthermore, the wireless communication system 10 also supports frequency bands higher than the FR2 frequency band. Specifically, the wireless communication system 10 supports frequency bands above 52.6 GHz and up to 71 GHz or 114.25 GHz. Such high frequency bands may be conveniently referred to as "FR2x".
　高周波数帯では位相雑音の影響が大きくなる問題を解決するため、52.6GHzを超える帯域を用いる場合、より大きなSub-Carrier Spacing（SCS）を有するCyclic Prefix-Orthogonal Frequency Division Multiplexing（CP-OFDM）／Discrete Fourier Transform - Spread（DFT-S-OFDM）を適用してもよい。 Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM)/ Discrete Fourier Transform - Spread (DFT-S-OFDM) may be applied.
　図３は、無線通信システム10において用いられる無線フレーム、サブフレーム及びスロットの構成例を示す。 FIG. 3 shows a configuration example of radio frames, subframes and slots used in the radio communication system 10. FIG.
　図３に示すように、１スロットは、１４シンボルで構成され、SCSが大きく（広く）なる程、シンボル期間（及びスロット期間）は短くなる。SCSは、図３に示す間隔（周波数）に限定されない。例えば、480kHz、960kHzなどが用いられてもよい。 As shown in FIG. 3, one slot consists of 14 symbols, and the larger (wider) the SCS, the shorter the symbol period (and slot period). The SCS is not limited to the intervals (frequencies) shown in FIG. For example, 480 kHz, 960 kHz, etc. may be used.
　また、１スロットを構成するシンボル数は、必ずしも１４シンボルでなくてもよい（例えば、２８、５６シンボル）。さらに、サブフレーム当たりのスロット数は、SCSによって異なっていてよい。 Also, the number of symbols forming one slot does not necessarily have to be 14 symbols (for example, 28 or 56 symbols). Furthermore, the number of slots per subframe may vary between SCSs.
　なお、図３に示す時間方向（t）は、時間領域、シンボル期間又はシンボル時間などと呼ばれてもよい。また、周波数方向は、周波数領域、リソースブロック、サブキャリア、バンド幅部分（BWP: Bandwidth part）などと呼ばれてもよい。 Note that the time direction (t) shown in FIG. 3 may be called the time domain, symbol period, symbol time, or the like. Also, the frequency direction may be called a frequency domain, resource block, subcarrier, bandwidth part (BWP), or the like.
　DMRSは、参照信号の一種であり、各種チャネル用に準備される。ここでは、特に断りがない限り、下りデータチャネル、具体的には、PDSCH（Physical Downlink Shared Channel）用のDMRSを意味してよい。但し、上りデータチャネル、具体的には、PUSCH（Physical Uplink Shared Channel）用のDMRSは、PDSCH用のDMRSと同様と解釈されてもよい。 DMRS is a type of reference signal and is prepared for various channels. Here, unless otherwise specified, it may mean a downlink data channel, specifically DMRS for PDSCH (Physical Downlink Shared Channel). However, an uplink data channel, specifically, a DMRS for PUSCH (Physical Uplink Shared Channel) may be interpreted in the same way as a DMRS for PDSCH.
　DMRSは、デバイス、例えば、コヒーレント復調の一部分として、UE200におけるチャネル推定に用い得る。DMRSは、PDSCH送信に使用されるリソースブロック（RB）のみに存在してよい。 DMRS can be used for channel estimation in devices, eg, UE 200, as part of coherent demodulation. DMRS may reside only in resource blocks (RBs) used for PDSCH transmission.
　DMRSは、複数のマッピングタイプを有してよい。具体的には、DMRSは、マッピングタイプA及びマッピングタイプBを有する。マッピングタイプAでは、最初のDMRSは、スロットの２又は３番目のシンボルに配置される。マッピングタイプAでは、DMRSは、実際のデータ送信がスロットのどこで開始されるかに関係なく、スロット境界を基準にしてマッピングされてよい。最初のDMRSがスロットの２又は３番目のシンボルに配置される理由は、制御リソースセット（CORESET：control resource sets）の後に最初のDMRSを配置するためと解釈されてもよい。 A DMRS may have multiple mapping types. Specifically, DMRS has mapping type A and mapping type B. For mapping type A, the first DMRS is placed in the 2nd or 3rd symbol of the slot. In mapping type A, the DMRS may be mapped relative to slot boundaries, regardless of where in the slot the actual data transmission begins. The reason the first DMRS is placed in the second or third symbol of the slot may be interpreted as to place the first DMRS after the control resource sets (CORESET).
　マッピングタイプBでは、最初のDMRSがデータ割り当ての最初のシンボルに配置されてよい。すなわち、DMRSの位置は、スロット境界に対してではなく、データが配置されている場所に対して相対的に与えられてよい。 In mapping type B, the first DMRS may be placed in the first symbol of data allocation. That is, the position of the DMRS may be given relative to where the data is located rather than relative to slot boundaries.
　また、DMRSは、複数の種類（Type）を有してよい。具体的には、DMRSは、Type 1及びType 2を有する。Type 1とType 2とは、周波数領域におけるマッピング及び直交参照信号（orthogonal reference signals）の最大数が異なる。Type 1は、単一シンボル（single-symbol）DMRSで最大４本の直交信号を出力でき、Type 2は、二重シンボル（double-symbol）DMRSで最大８本の直交信号を出力できる。 In addition, DMRS may have multiple types (Type). Specifically, DMRS has Type 1 and Type 2. Type 1 and Type 2 differ in mapping in the frequency domain and the maximum number of orthogonal reference signals. Type 1 can output up to 4 orthogonal signals with single-symbol DMRS, and Type 2 can output up to 8 orthogonal signals with double-symbol DMRS.
　（２）無線通信システムの機能ブロック構成
　次に、無線通信システム10の機能ブロック構成について説明する。 (2) Functional Block Configuration of Radio Communication System Next, the functional block configuration of the radio communication system 10 will be described.
　第１に、UE200の機能ブロック構成について説明する。 First, the functional block configuration of the UE200 will be explained.
　図４は、UE200の機能ブロック構成図である。図４に示すように、UE200は、無線信号送受信部210、アンプ部220、変復調部230、制御信号・参照信号処理部240、符号化/復号部250、データ送受信部260及び制御部270を備える。 FIG. 4 is a functional block diagram of the UE200. As shown in FIG. 4, the UE 200 includes a radio signal transmission/reception unit 210, an amplifier unit 220, a modem unit 230, a control signal/reference signal processing unit 240, an encoding/decoding unit 250, a data transmission/reception unit 260, and a control unit 270. .
　無線信号送受信部210は、NRに従った無線信号を送受信する。無線信号送受信部210は、Massive MIMO、複数のCCを束ねて用いるCA、及びUEと２つのNG-RAN Nodeそれぞれとの間において同時に通信を行うDCなどに対応する。 The radio signal transmitting/receiving unit 210 transmits/receives radio signals according to NR. The radio signal transmitting/receiving unit 210 supports Massive MIMO, CA that bundles multiple CCs, and DC that simultaneously communicates between the UE and each of the two NG-RAN Nodes.
　アンプ部220は、PA (Power Amplifier)/LNA (Low Noise Amplifier)などによって構成される。アンプ部220は、変復調部230から出力された信号を所定の電力レベルに増幅する。また、アンプ部220は、無線信号送受信部210から出力されたRF信号を増幅する。 The amplifier section 220 is configured by a PA (Power Amplifier)/LNA (Low Noise Amplifier) and the like. Amplifier section 220 amplifies the signal output from modem section 230 to a predetermined power level. In addition, amplifier section 220 amplifies the RF signal output from radio signal transmission/reception section 210 .
　変復調部230は、所定の通信先（gNB100又は他のgNB）毎に、データ変調／復調、送信電力設定及びリソースブロック割当などを実行する。変復調部230では、Cyclic Prefix-Orthogonal Frequency Division Multiplexing（CP-OFDM）／Discrete Fourier Transform - Spread（DFT-S-OFDM）が適用されてもよい。また、DFT-S-OFDMは、上りリンク（UL）だけでなく、下りリンク（DL）にも用いられてもよい。 The modulation/demodulation unit 230 executes data modulation/demodulation, transmission power setting, resource block allocation, etc. for each predetermined communication destination (gNB 100 or other gNB). The modem unit 230 may apply Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM)/Discrete Fourier Transform-Spread (DFT-S-OFDM). Also, DFT-S-OFDM may be used not only for uplink (UL) but also for downlink (DL).
　制御信号・参照信号処理部240は、UE200が送受信する各種の制御信号に関する処理、及びUE200が送受信する各種の参照信号に関する処理を実行する。 The control signal/reference signal processing unit 240 executes processing related to various control signals transmitted and received by the UE 200 and processing related to various reference signals transmitted and received by the UE 200.
　具体的には、制御信号・参照信号処理部240は、gNB100から所定の制御チャネルを介して送信される各種の制御信号、例えば、無線リソース制御レイヤ（RRC）の制御信号を受信する。また、制御信号・参照信号処理部240は、gNB100に向けて、所定の制御チャネルを介して各種の制御信号を送信する。 Specifically, the control signal/reference signal processing unit 240 receives various control signals transmitted from the gNB 100 via a predetermined control channel, for example, radio resource control layer (RRC) control signals. Also, the control signal/reference signal processing unit 240 transmits various control signals to the gNB 100 via a predetermined control channel.
　制御信号・参照信号処理部240は、Demodulation Reference Signal（DMRS）、及びPhase Tracking Reference Signal （PTRS）などの参照信号（RS）を用いた処理を実行する。 The control signal/reference signal processing unit 240 executes processing using reference signals (RS) such as Demodulation Reference Signal (DMRS) and Phase Tracking Reference Signal (PTRS).
　DMRSは、データ復調に用いるフェージングチャネルを推定するための端末個別の基地局～端末間において既知の参照信号（パイロット信号）である。PTRSは、高い周波数帯で課題となる位相雑音の推定を目的した端末個別の参照信号である。 A DMRS is a known reference signal (pilot signal) between a terminal-specific base station and a terminal for estimating the fading channel used for data demodulation. PTRS is a terminal-specific reference signal for estimating phase noise, which is a problem in high frequency bands.
　なお、参照信号には、DMRS及びPTRS以外に、Channel State Information-Reference Signal（CSI-RS）、Sounding Reference Signal（SRS）、及び位置情報用のPositioning Reference Signal（PRS）が含まれてもよい。 In addition to DMRS and PTRS, reference signals may include Channel State Information-Reference Signal (CSI-RS), Sounding Reference Signal (SRS), and Positioning Reference Signal (PRS) for position information.
　また、チャネルには、制御チャネルとデータチャネルとが含まれる。制御チャネルには、PDCCH（Physical Downlink Control Channel）、PUCCH（Physical Uplink Control Channel）、RACH（Random Access Channel）、Random Access Radio Network Temporary Identifier(RA-RNTI)を含むDownlink Control Information (DCI)）、及びPhysical Broadcast Channel（PBCH）などが含まれる。 Also, the channel includes a control channel and a data channel. Control channels include Physical Downlink Control Channel (PDCCH), Physical Uplink Control Channel (PUCCH), Random Access Channel (RACH), Downlink Control Information (DCI) including Random Access Radio Network Temporary Identifier (RA-RNTI), and Physical Broadcast Channel (PBCH) etc. are included.
　また、データチャネルには、PDSCH（Physical Downlink Shared Channel）、及びPUSCH（Physical Uplink Shared Channel）などが含まれる。データとは、データチャネルを介して送信されるデータを意味する。データチャネルは、共有チャネルと読み替えられてもよい。 In addition, data channels include PDSCH (Physical Downlink Shared Channel) and PUSCH (Physical Uplink Shared Channel). Data means data transmitted over a data channel. A data channel may be read as a shared channel.
　ここで、制御信号・参照信号処理部240は、下りリンク制御情報（DCI）を受信してもよい。DCIは、既存のフィールドとして、DCI Formats、Carrier indicator（CI）、BWP indicator、FDRA（Frequency Domain Resource Allocation）、TDRA（Time Domain Resource Allocation）、MCS（Modulation and Coding Scheme）、HPN（HARQ Process Number）、NDI（New Data Indicator）、RV（Redundancy Version）などを格納するフィールドを含む。 Here, the control signal/reference signal processing unit 240 may receive downlink control information (DCI). DCI has existing fields such as DCI Formats, Carrier indicator (CI), BWP indicator, FDRA (Frequency Domain Resource Allocation), TDRA (Time Domain Resource Allocation), MCS (Modulation and Coding Scheme), HPN (HARQ Process Number) , NDI (New Data Indicator), RV (Redundancy Version), etc.

The value stored in the RV field is an information element that specifies the data redundancy to which DCI is applied.
　実施形態では、制御信号・参照信号処理部240は、第１優先度の上りリンク共有チャネル（PUSCH）に対する第２優先度の上りリンク制御情報（UCI）の多重に関する有効化及び無効化の少なくともいずれか１つを明示的又は暗黙的に示す情報要素をネットワークから受信する通信部を構成する。 In the embodiment, the control signal/reference signal processing unit 240 at least either enables or disables multiplexing of the second priority uplink control information (UCI) for the first priority uplink shared channel (PUSCH). constitutes a communication unit that receives from the network an information element that explicitly or implicitly indicates one of
　符号化/復号部250は、所定の通信先（gNB100又は他のgNB）毎に、データの分割／連結及びチャネルコーディング／復号などを実行する。 The encoding/decoding unit 250 performs data segmentation/concatenation, channel coding/decoding, etc. for each predetermined communication destination (gNB 100 or other gNB).
　具体的には、符号化/復号部250は、データ送受信部260から出力されたデータを所定のサイズに分割し、分割されたデータに対してチャネルコーディングを実行する。また、符号化/復号部250は、変復調部230から出力されたデータを復号し、復号したデータを連結する。 Specifically, the encoding/decoding unit 250 divides the data output from the data transmission/reception unit 260 into pieces of a predetermined size, and performs channel coding on the divided data. Also, encoding/decoding section 250 decodes the data output from modem section 230 and concatenates the decoded data.
　データ送受信部260は、Protocol Data Unit (PDU)ならびにService Data Unit (SDU)の送受信を実行する。具体的には、データ送受信部260は、複数のレイヤ（媒体アクセス制御レイヤ（MAC）、無線リンク制御レイヤ（RLC）、及びパケット・データ・コンバージェンス・プロトコル・レイヤ（PDCP）など）におけるPDU/SDUの組み立て／分解などを実行する。また、データ送受信部260は、HARQ（Hybrid Automatic Repeat Request）に基づいて、データの誤り訂正及び再送制御を実行する。 The data transmission/reception unit 260 executes transmission/reception of Protocol Data Unit (PDU) and Service Data Unit (SDU). Specifically, the data transmitting/receiving unit 260 performs PDU/SDU in multiple layers (medium access control layer (MAC), radio link control layer (RLC), packet data convergence protocol layer (PDCP), etc.). Assemble/disassemble etc. The data transmission/reception unit 260 also performs data error correction and retransmission control based on HARQ (Hybrid Automatic Repeat Request).
　制御部270は、UE200を構成する各機能ブロックを制御する。実施形態では、制御部270は、PUSCHに対するUCIの多重を制御する制御部を構成する。制御部270は、PUSCHの優先度とUCIの優先度が同じ場合に、PUSCHに対するUCIの多重を制御してもよい。制御部270は、PUSCHの優先度がUCIの優先度と異なる場合に、PUSCHに対するUCIの多重を制御してもよい。 The control unit 270 controls each functional block that configures the UE200. In the embodiment, the control unit 270 constitutes a control unit that controls multiplexing of UCI to PUSCH. Control section 270 may control multiplexing of UCI to PUSCH when the priority of PUSCH and the priority of UCI are the same. The control unit 270 may control multiplexing of UCI to PUSCH when the priority of PUSCH is different from the priority of UCI.
　ここで、PUSCH及びUCIの優先度としては、第１優先度及び第２優先度が想定されてもよい。第１優先度は、第２優先度と異なる。PUSCH及びUCIの優先度として、HP（High Priority）及びLP（Low Priority）の２タイプについて例示する。第１優先度がHPであり、第２優先度がLPであってもよく、第１優先度がLPであり、第２優先度がHPであってもよい。UCIの優先度として３タイプ以上の優先度が定められてもよい。 Here, as the priority of PUSCH and UCI, the first priority and the second priority may be assumed. The first priority is different from the second priority. Two types of HP (High Priority) and LP (Low Priority) are exemplified as the priority of PUSCH and UCI. The first priority may be HP and the second priority may be LP, or the first priority may be LP and the second priority may be HP. Three or more types of priority may be defined as the UCI priority.
　このような前提下において、PUSCHの優先度がUCIの優先度と異なる場合においては、制御部270は、NG RAN20（gNB100）から受信する情報要素に基づいて、第１優先度のPUSCHに対する第２優先度のUCIの多重を制御してもよい。 Under this premise, when the priority of PUSCH is different from the priority of UCI, the control unit 270, based on the information elements received from the NG RAN 20 (gNB 100), sets the second Priority UCI multiplexing may be controlled.
　UCIは、１以上のTBに対する確認応答（HARQ-ACK）を含んでもよい。UCIは、リソースのスケジューリングを要求するSR（Scheduling Request）を含んでもよく、チャネルの状態を表すCSI（Channel State Information）を含んでもよい。 A UCI may contain an acknowledgment (HARQ-ACK) for one or more TBs. The UCI may include an SR (Scheduling Request) requesting resource scheduling, and may include a CSI (Channel State Information) representing the channel state.
　なお、制御部270は、上述した制御信号・参照信号処理部240を制御しており、制御信号・参照信号処理部240は、UCIが多重されたPUSCHを介して、上りリンク信号を送信する通信部を構成してもよい。 Note that the control unit 270 controls the control signal/reference signal processing unit 240 described above, and the control signal/reference signal processing unit 240 performs communication for transmitting an uplink signal via PUSCH multiplexed with UCI. may constitute a part.
　第２に、gNB100の機能ブロック構成について説明する。 Second, the functional block configuration of gNB100 will be explained.
　図５は、gNB100の機能ブロック構成図である。図５に示すように、gNB100は、受信部110、送信部120及び制御部130を有する。 FIG. 5 is a functional block configuration diagram of gNB100. As shown in FIG. 5, the gNB 100 has a receiver 110, a transmitter 120 and a controller .
　受信部110は、UE200から各種信号を受信する。受信部110は、PUCCH又はPUSCHを介してUL信号を受信してもよい。 The receiving unit 110 receives various signals from the UE200. The receiver 110 may receive the UL signal via PUCCH or PUSCH.
　送信部120は、UE200に各種信号を送信する。送信部120は、PDCCH又はPDSCHを介してDL信号を送信してもよい。実施形態では、送信部120は、第１優先度のPUSCHに対する第２優先度のUCIの多重に関する有効化及び無効化の少なくともいずれか１つを明示的又は暗黙的に示す情報要素をUE200に送信する通信部を構成する。 The transmission unit 120 transmits various signals to the UE200. Transmitting section 120 may transmit the DL signal via PDCCH or PDSCH. In the embodiment, the transmitting unit 120 transmits to the UE 200 an information element that explicitly or implicitly indicates at least one of enabling and disabling multiplexing of the second priority UCI to the first priority PUSCH. configures a communication unit that
　制御部130は、gNB100を制御する。制御部130は、UE200に送信する情報要素に基づいて、PUSCHを介した上りリンク信号の受信を想定する制御部を構成する。例えば、制御部130は、UE200に送信する情報要素が有効化を明示的又は暗黙的に示す場合に、PUSCHに多重されたUCIの受信を想定してもよい。制御部130は、UE200に送信する情報要素が無効化を明示的又は暗黙的に示す場合に、PUSCHに多重されたUCIの受信を想定しなくてもよい。 The control unit 130 controls the gNB100. Control section 130 configures a control section that assumes reception of uplink signals via PUSCH based on information elements to be transmitted to UE 200 . For example, control section 130 may assume reception of UCI multiplexed on PUSCH when an information element to be transmitted to UE 200 explicitly or implicitly indicates activation. Control section 130 may not assume reception of UCI multiplexed on PUSCH when the information element to be transmitted to UE 200 explicitly or implicitly indicates invalidation.
　（３）レートマッチング
　以下において、レートマッチングについて説明する。具体的には、UCIをUL SCHに多重するケースにおけるUCIのレートマッチングについて説明する。ここでは、UCIとして、HARQ-ACK、CSI Part 1、CSI Part 2について例示する。なお、HARQ-ACK、CSI-Part 1及びCSI-Part 2は別々に実行される。 (3) Rate Matching Rate matching will be described below. Specifically, UCI rate matching in the case of multiplexing UCI to UL SCH will be described. Here, HARQ-ACK, CSI Part 1, and CSI Part 2 are exemplified as UCI. Note that HARQ-ACK, CSI-Part 1 and CSI-Part 2 are performed separately.
　図６に示すように、”X0、X1、…”のビット系列を有するHARQ-ACKに対してチャネル符号化が適用されることによって”C00、C01、…”のビット系列が得られる。このようなビット系列に対してレートマッチングが適用される。レートマッチング後のビット系列（EUCI）は、EUCI＝NL×Q’ACK×Qmによって表されてもよい。 As shown in FIG. 6, a bit sequence of "C00, C01, ..." is obtained by applying channel coding to HARQ-ACK having a bit sequence of " X0 , X1, ...". Rate matching is applied to such bit sequences. The bit sequence after rate matching (E UCI ) may be represented by E UCI =N L ×Q′ ACK ×Q m .
　NLは、PUSCHの送信レイヤの数である。Qmは、PUSCHの変調条件である。例えば、Q’ACKは、以下の式によって表される（TS38.212 V16.3.0 §6.3.2.4.1.1 “HARQ-ACK”）。 NL is the number of PUSCH transmission layers. Q m is the PUSCH modulation condition. For example, Q' ACK is represented by the following formula (TS38.212 V16.3.0 §6.3.2.4.1.1 "HARQ-ACK").

　なお、Q’ACKは、係数（β）によって定義される項目（左側）及びスケーリングファクタ（α）によって定義される項目（右側）の最小値である。従って、HARQ-ACKの送信に用いるRE（Resource Element）は、スケーリングファクタ（α）によって制限され得ることに留意すべきである。 Note that Q' ACK is the minimum value of the item (left side) defined by the coefficient (β) and the item (right side) defined by the scaling factor (α). Therefore, it should be noted that the RE (Resource Element) used for HARQ-ACK transmission may be limited by the scaling factor (α).
　図７に示すように、”Y0、Y1、…”のビット系列を有するCSI Part 1に対してチャネル符号化が適用されることによって”C00、C01、…”のビット系列が得られる。このようなビット系列に対してレートマッチングが適用される。レートマッチング後のビット系列（EUCI）は、EUCI＝NL×Q’CSI-part1×Qmによって表されてもよい。 As shown in FIG. 7, a bit sequence of "C00, C01, ..." is obtained by applying channel coding to CSI Part 1 having a bit sequence of "Y0, Y1, ...". Rate matching is applied to such bit sequences. The bit sequence after rate matching (E UCI ) may be represented by E UCI =N L ×Q′ CSI-part1 ×Q m .
　NLは、PUSCHの送信レイヤの数である。Qmは、PUSCHの変調条件である。例えば、Q’CSI-part1は、以下の式によって表される（TS38.212 V16.3.0 §6.3.2.4.1.2 “CSI part 1”）。 NL is the number of PUSCH transmission layers. Q m is the PUSCH modulation condition. For example, Q' CSI- part1 is represented by the following formula (TS38.212 V16.3.0 §6.3.2.4.1.2 "CSI part 1").

　なお、Q’ACKは、係数（β）によって定義される項目（左側）及びスケーリングファクタ（α）によって定義される項目（右側）の最小値である。従って、CSI Part 1の送信に用いるRE（Resource Element）は、スケーリングファクタ（α）によって制限され得ることに留意すべきである。 Note that Q' ACK is the minimum value of the item (left side) defined by the coefficient (β) and the item (right side) defined by the scaling factor (α). Therefore, it should be noted that the RE (Resource Element) used for transmitting CSI Part 1 can be limited by the scaling factor (α).
　図８に示すように、”Z 0、Z1、…”のビット系列を有するCSI Part 2に対してチャネル符号化が適用されることによって”C00、C01、…”のビット系列が得られる。このようなビット系列に対してレートマッチングが適用される。レートマッチング後のビット系列（EUCI）は、EUCI＝NL×Q’CSI-part2×Qmによって表されてもよい。 As shown in FIG. 8, a bit sequence of "C00, C01, ..." is obtained by applying channel coding to CSI Part 2 having a bit sequence of " Z0 , Z1, ...". Rate matching is applied to such bit sequences. The bit sequence after rate matching (E UCI ) may be represented by E UCI =N L ×Q′ CSI-part2 ×Q m .
　NLは、PUSCHの送信レイヤの数である。Qmは、PUSCHの変調条件である。例えば、Q’CSI-part2は、以下の式によって表される（TS38.212 V16.3.0 §6.3.2.4.1.3 “CSI part 2”）。 NL is the number of PUSCH transmission layers. Q m is the PUSCH modulation condition. For example, Q' CSI- part2 is represented by the following formula (TS38.212 V16.3.0 §6.3.2.4.1.3 "CSI part 2").

　なお、Q’ACKは、係数（β）によって定義される項目（左側）及びスケーリングファクタ（α）によって定義される項目（右側）の最小値である。従って、CSI Part 2の送信に用いるRE（Resource Element）は、スケーリングファクタ（α）によって制限され得ることに留意すべきである。 Note that Q' ACK is the minimum value of the item (left side) defined by the coefficient (β) and the item (right side) defined by the scaling factor (α). Therefore, it should be noted that the RE (Resource Element) used for transmitting CSI Part 2 can be limited by the scaling factor (α).
　（４）動作例
　以下において、実施形態の動作例について説明する。以下においては、LP UCIをHP PUSCHに多重するケース、LP UCI及びHP UCIをHP PUSCHに多重するケースについて説明する。LP UCI及びHP UCIをHP PUSCHに多重するケースにおいても、LP UCIがHP PUSCHに多重されるため、説明簡略化のために、LP UCIをHP PUSCHに多重するケースについて例示する。 (4) Operation Example An operation example of the embodiment will be described below. In the following, a case of multiplexing LP UCI with HP PUSCH and a case of multiplexing LP UCI and HP UCI with HP PUSCH will be described. Even in the case of multiplexing LP UCI and HP UCI to HP PUSCH, LP UCI is multiplexed to HP PUSCH, so for the sake of simplicity of explanation, the case of multiplexing LP UCI to HP PUSCH will be exemplified.
　このようなケースにおいては、LP UCIの多重によってHP PUSCHのリソースが減少するため、HP PUSCHのリソースを適切に確保するために、HP PUSCHに対するLP UCIの多重を有効化する否かの選択が要求される。以下においては、HP PUSCHに対するLP UCIの多重を有効化するか否かを選択する方法について説明する。 In such a case, multiplexing of LP UCI reduces HP PUSCH resources, so in order to appropriately secure HP PUSCH resources, it is necessary to select whether to enable LP UCI multiplexing for HP PUSCH. be done. A method for selecting whether to enable multiplexing of LP UCI to HP PUSCH is described below.
　（４．１）動作例１
　動作例１では、上述した係数（β）として、新たな係数（new β）が定義（追加）される。新たな係数（new β）は、PUSCHの優先度がUCIの優先度と異なるケースで適用される係数である。新たな係数（new β）の取り得る範囲（以下、拡張範囲）は、既定範囲において係数（β）が取り得る値の最小値”1.000”よりも小さい値を含む。拡張範囲は、少なくとも”0”を含んでもよい。既定範囲とは、TS38.213 V16.5.0 §9.3 “UCI reporting in physical uplink shared channel”で規定される範囲であってもよい。 (4.1) Operation example 1
In operation example 1, a new coefficient (new β) is defined (added) as the coefficient (β) described above. A new coefficient (new β) is a coefficient applied when the priority of PUSCH is different from that of UCI. The possible range of the new coefficient (new β) (hereinafter referred to as extended range) includes values smaller than the minimum value "1.000" of the possible values of the coefficient (β) in the default range. The extended range may include at least "0". The default range may be the range specified in TS38.213 V16.5.0 §9.3 “UCI reporting in physical uplink shared channel”.
　言い換えると、HP PUSCHに対するLP UCIの多重に関する有効化及び無効化の少なくともいずれか１つを明示的又は暗黙的に示す情報要素は、NG RAN20（gNB100）から受信するDCIに含まれ、UCIのレートマッチングにおいてUCIを構成するビット数に乗算される新たな係数（β）を指定する第１情報要素であってもよい。新たな係数（β）は、NG RAN20（gNB100）から受信するDCIに含まれるフィールド（例えば、beta_offset indicator field）によって指定され得る。すなわち、新たな係数（β）が”0”である場合に、HP PUSCHに対するLP UCIの多重が無効化される。一方で、新たな係数（β）が”0”よりも大きな値である場合に、HP PUSCHに対するLP UCIの多重が有効化される。 In other words, an information element that explicitly or implicitly indicates at least one of enabling and disabling multiplexing of LP UCI to HP PUSCH is included in the DCI received from NG RAN20 (gNB100), and the rate of UCI It may be a first information element specifying a new factor (β) by which the number of bits forming the UCI is multiplied in matching. The new factor (β) may be specified by a field (eg, beta_offset indicator field) included in DCI received from NG RAN20 (gNB100). That is, when the new coefficient (β) is "0", multiplexing of LP UCI to HP PUSCH is disabled. On the other hand, multiplexing of LP UCI to HP PUSCH is enabled when the new coefficient (β) is greater than "0".
　このようなケースにおいて、DCIは、PUSCHの優先度がUCIの優先度と同じであるケース（以下、same priority multiplexing）で用いる係数（β）、PUSCHの優先度がUCIの優先度と異なるケース（以下、different priority multiplexing）で用いる新たな係数（β）を別々に指定する情報要素を含んでもよい。same priority multiplexingで用いる係数（β）を指定する情報要素としては、既に定義されたbeta_offset indicator field（以下、existing beta_offset indicator field）が用いられてもよい。different priority multiplexingで用いる新たな係数（β）を指定する情報要素としては、新たに定義（追加）されるbeta_offset indicator field（以下、new beta_offset indicator field）が用いられてもよい。 In such cases, DCI is a factor (β) used in cases where the priority of PUSCH is the same as the priority of UCI (hereinafter, same priority multiplexing), and a case where the priority of PUSCH is different from the priority of UCI ( An information element that separately specifies a new coefficient (β) to be used in different priority multiplexing may be included. An already defined beta_offset indicator field (hereinafter, existing beta_offset indicator field) may be used as an information element that specifies the coefficient (β) used in same priority multiplexing. As an information element specifying a new coefficient (β) used in different priority multiplexing, a newly defined (added) beta_offset indicator field (hereinafter, new beta_offset indicator field) may be used.
　さらに、same priority multiplexingで用いる係数（β）及びdifferent priority multiplexingで用いる新たな係数（β）に関する設定（以下、beta-offset configuration）は、RRCメッセージ（パラメータ）によって別々に設定されてもよい。beta-offset configurationは、beta_offset indicator fieldによって指定し得る係数（β）の候補（beta-offset table）であると考えてもよい。same priority multiplexingに関するbeta-offset configurationは、既に定義されたUCI-OnPUSCHによって設定されてもよい。different priority multiplexingに関するbeta-offset configurationは、新たに定義（追加）されるUCI-OnPUSCH-diffPrioによって設定されてもよい。 Furthermore, the settings for the coefficient (β) used in same priority multiplexing and the new coefficient (β) used in different priority multiplexing (hereinafter referred to as beta-offset configuration) may be set separately by RRC messages (parameters). A beta-offset configuration may be thought of as a candidate (beta-offset table) for coefficients (β) that may be specified by the beta_offset indicator field. The beta-offset configuration for same priority multiplexing may be set by the already defined UCI-OnPUSCH. A beta-offset configuration for different priority multiplexing may be set by a newly defined (added) UCI-OnPUSCH-diffPrio.
　例えば、係数（β）がexisting beta_offset indicator fieldによって指定される場合に、係数（β）は、UCI-OnPUSCHによって設定されたbeta-offset tableの中から選択される。一方で、新たな係数（β）がnew beta_offset indicator fieldによって指定される場合に、新たな係数（β）は、UCI-OnPUSCH-diffPrioによって設定されたbeta-offset tableの中から選択される。 For example, if the coefficient (β) is specified by the existing beta_offset indicator field, the coefficient (β) is selected from the beta-offset table set by UCI-OnPUSCH. On the other hand, if the new factor (β) is specified by the new beta_offset indicator field, the new factor (β) is selected from the beta-offset table set by UCI-OnPUSCH-diffPrio.
　ここで、NG RAN20及びUE200の動作について図９を参照しながら説明する。図９では、HP PUSCHに対するLP UCIの多重を有効化するか否かに関する動作について主として説明する。 Here, the operations of NG RAN 20 and UE 200 will be described with reference to FIG. FIG. 9 mainly describes the operation regarding whether to enable multiplexing of LP UCI to HP PUSCH.
　図９に示すように、ステップS10において、UE200は、UE Capabilityを含むメッセージをNG-RAN20に送信する。UE Capabilityは、新たな係数（β）に対応する機能をUE200が有しているか否かを明示的又は暗黙的に示す情報要素を含んでもよい。 As shown in FIG. 9, in step S10, UE 200 transmits a message including UE Capability to NG-RAN 20. UE Capability may include an information element that explicitly or implicitly indicates whether the UE 200 has the capability to support the new coefficient (β).
　ステップS11において、UE100は、RRCメッセージをNG-RAN20から受信する。RRCメッセージは、different priority multiplexingに関するUCI-OnPUSCH-diffPrioを含んでもよい。RRCメッセージは、same priority multiplexingに関するUCI-OnPUSCHを含んでもよい。 　In step S11, the UE 100 receives the RRC message from the NG-RAN 20. The RRC message may contain UCI-OnPUSCH-diffPrio for different priority multiplexing. The RRC message may contain UCI-OnPUSCH for same priority multiplexing.
　ステップS12において、UE200は、PDCCHを介してDCIをNG-RAN20から受信する。DCIは、different priority multiplexingで用いる新たな係数（β）を指定する第１情報要素（new beta_offset indicator field）を含んでもよい。DCIは、same priority multiplexingで用いる係数（β）を指定する情報要素（existing beta_offset indicator field）を含んでもよい。 In step S12, UE 200 receives DCI from NG-RAN 20 via PDCCH. DCI may include a first information element (new beta_offset indicator field) that specifies a new coefficient (β) to be used in different priority multiplexing. DCI may contain an information element (existing beta_offset indicator field) that specifies the coefficient (β) used in same priority multiplexing.
　ステップS13において、UE200は、新たな係数（β）が”0”よりも大きい場合に、HP PUSCHに対するLP UCIの多重を有効化する。UE200は、LP UCIをHP PUSCHに多重した上で、HP PUSHを介して上りリンク信号を送信する。一方で、UE200は、新たな係数（β）が”0”である場合に、HP PUSCHに対するLP UCIの多重を無効化する。UE200は、LP UCIをHP PUSCHに多重せずに、HP PUSHを介して上りリンク信号を送信する。 In step S13, the UE 200 enables multiplexing of LP UCI to HP PUSCH when the new coefficient (β) is greater than "0". The UE 200 multiplexes the LP UCI to the HP PUSCH and then transmits an uplink signal via the HP PUSH. On the other hand, the UE 200 disables multiplexing of LP UCI to HP PUSCH when the new coefficient (β) is "0". UE 200 transmits an uplink signal via HP PUSH without multiplexing LP UCI on HP PUSCH.
　このような構成によれば、beta-offset configuration（beta-offset table）を柔軟に設定することができるため、HP PUSCHのリソースの減少を柔軟に抑制しながら、HP PUSCHの信頼性が向上することができる。 With this configuration, the beta-offset configuration (beta-offset table) can be flexibly set, so HP PUSCH reliability can be improved while flexibly suppressing HP PUSCH resource reduction. can be done.
　なお、動作例１では、係数（β）が動的に指定されるケース（Dynamic beta-offset）が想定されているため、動作例１は、DG（Dynamic Grant） PUSCHに適用されてもよい。新たな係数（β）を指定するnew beta_offset indicator fieldは、新たな係数（β）を指定するbitと読み替えられてもよい。 In operation example 1, a case (Dynamic beta-offset) in which the coefficient (β) is dynamically specified is assumed, so operation example 1 may be applied to DG (Dynamic Grant) PUSCH. A new beta_offset indicator field that specifies a new coefficient (β) may be read as a bit that specifies a new coefficient (β).
　（４．２）動作例２
　動作例２では、新たなDCI field（以下、new DCI field）が定義（追加）される。new DCI fieldは、HP PUSCHに対するLP UCIの多重に関する有効化及び無効化の少なくともいずれか１つを指定するフィールドである。 (4.2) Operation example 2
In operation example 2, a new DCI field (hereinafter referred to as new DCI field) is defined (added). The new DCI field is a field that specifies at least one of enabling and disabling multiplexing of LP UCI to HP PUSCH.
　言い換えると、HP PUSCHに対するLP UCIの多重に関する有効化及び無効化の少なくともいずれか１つを明示的又は暗黙的に示す情報要素は、NG RAN20（gNB100）から受信するDCIに含まれ、有効化及び無効化の少なくともいずれか１つを指定する第２情報要素（new DCI field）であってもよい。new DCI fieldは、1bitで構成されてもよい。例えば、”0”は、HP PUSCHに対するLP UCIの多重の有効化を意味し、”1”は、HP PUSCHに対するLP UCIの多重の無効化を意味してもよい。逆に、”0”は、HP PUSCHに対するLP UCIの多重の無効化を意味し、”1”は、HP PUSCHに対するLP UCIの多重の有効化を意味してもよい。 In other words, an information element that explicitly or implicitly indicates at least one of enabling and disabling multiplexing of LP UCI to HP PUSCH is included in the DCI received from NG RAN20 (gNB100), enabling and It may be a second information element (new DCI field) that specifies at least one of the invalidations. The new DCI field may consist of 1 bit. For example, "0" may mean enable multiplexing of LP UCI to HP PUSCH, and "1" may mean disable multiplexing of LP UCI to HP PUSCH. Conversely, "0" may mean disabling multiplexing of LP UCI for HP PUSCH, and "1" may mean enabling multiplexing of LP UCI for HP PUSCH.
　ここで、new DCI fieldを含むDCIとしては、対応するPUSCHをスケジューリングするためのUL Grant DCIが用いられてもよく、対応するPUCCHと関連付けられた下りリンクチャネルをスケジューリングするためのDL Grant DCIが用いられてもよい。new DCI fieldを含むDCIとしては、対応するPUSCH及び対応するPUCCHとは無関係に送信されるDCIが用いられてもよい。 Here, as the DCI including the new DCI field, the UL Grant DCI for scheduling the corresponding PUSCH may be used, and the DL Grant DCI for scheduling the downlink channel associated with the corresponding PUCCH is used. may be A DCI that is transmitted independently of the corresponding PUSCH and the corresponding PUCCH may be used as the DCI including the new DCI field.
　動作例２では、HP PUSCHに対するLP UCIの多重が有効化されており、かつ、RRCメッセージ（パラメータ）に含まれるPUSCH-Config又はCG（Configured Grant）-UCI-OnPUSCHによってDynamic beta-offsetが設定されている場合に、new DCI fieldを含むDCIに含まれるbeta_offset indicator fieldは、same priority multiplexing及びdifferent priority multiplexingで用いる係数（β）を指定してもよい。動作例２では、動作例１とは異なり、新たな係数（β）を指定するnew beta_offset indicator fieldが定義される必要がないことに留意すべきである。 In operation example 2, multiplexing of LP UCI to HP PUSCH is enabled, and Dynamic beta-offset is set by PUSCH-Config or CG (Configured Grant)-UCI-OnPUSCH included in the RRC message (parameter). , the beta_offset indicator field included in the DCI containing the new DCI field may specify the factor (β) used for same priority multiplexing and different priority multiplexing. Note that in operation example 2, unlike operation example 1, it is not necessary to define a new beta_offset indicator field that specifies a new coefficient (β).
　ここで、NG RAN20及びUE200の動作について図１０を参照しながら説明する。図１０では、HP PUSCHに対するLP UCIの多重を有効化するか否かに関する動作について主として説明する。 Here, the operations of the NG RAN 20 and the UE 200 will be explained with reference to FIG. FIG. 10 mainly describes the operation regarding whether to enable multiplexing of LP UCI to HP PUSCH.
　図１０に示すように、ステップS20において、UE200は、UE Capabilityを含むメッセージをNG-RAN20に送信する。UE Capabilityは、new DCI fieldに対応する機能をUE200が有しているか否かを明示的又は暗黙的に示す情報要素を含んでもよい。 As shown in FIG. 10, in step S20, UE 200 transmits a message including UE Capability to NG-RAN 20. UE Capability may include an information element that explicitly or implicitly indicates whether the UE 200 has the capability corresponding to the new DCI field.
　ステップS21において、UE100は、RRCメッセージをNG-RAN20から受信する。RRCメッセージは、same priority multiplexing及びdifferent priority multiplexingの双方に関するUCI-OnPUSCH又はCG UCI-OnPUSCHを含んでもよい。 　In step S21, the UE 100 receives the RRC message from the NG-RAN 20. The RRC message may include UCI-OnPUSCH or CG UCI-OnPUSCH for both same priority multiplexing and different priority multiplexing.
　ステップS22において、UE200は、PDCCHを介してDCIをNG-RAN20から受信する。DCIは、HP PUSCHに対するLP UCIの多重に関する有効化及び無効化の少なくともいずれか１つを指定する第２情報要素（new DCI field）を含む。DCIは、same priority multiplexing及びdifferent priority multiplexingで用いる係数（β）を指定するbeta_offset indicator fieldを含んでもよい。 In step S22, UE 200 receives DCI from NG-RAN 20 via PDCCH. DCI includes a second information element (new DCI field) that specifies at least one of enabling and disabling multiplexing of LP UCI to HP PUSCH. A DCI may include a beta_offset indicator field that specifies the factor (β) used in same priority multiplexing and different priority multiplexing.
　ステップS23において、UE200は、HP PUSCHに対するLP UCIの多重の有効化をnew DCI fieldが指定する場合に、HP PUSCHに対するLP UCIの多重を有効化する。UE200は、LP UCIをHP PUSCHに多重した上で、HP PUSHを介して上りリンク信号を送信する。一方で、UE200は、HP PUSCHに対するLP UCIの多重の無効化をnew DCI fieldが指定する場合に、HP PUSCHに対するLP UCIの多重を無効化する。UE200は、LP UCIをHP PUSCHに多重せずに、HP PUSHを介して上りリンク信号を送信する。 In step S23, the UE 200 enables LP UCI multiplexing for HP PUSCH when the new DCI field specifies enabling LP UCI multiplexing for HP PUSCH. The UE 200 multiplexes the LP UCI to the HP PUSCH and then transmits an uplink signal via the HP PUSH. On the other hand, the UE 200 disables LP UCI multiplexing for HP PUSCH when the new DCI field specifies disabling LP UCI multiplexing for HP PUSCH. UE 200 transmits an uplink signal via HP PUSH without multiplexing LP UCI to HP PUSCH.
　このような構成によれば、new DCI fieldを1bitで表すことができるため、DCIのオーバヘッドの増大を抑制しながら、HP PUSCHに対するLP UCIの多重を無効化することができ、HP PUSCHの信頼性を向上することができる。 With such a configuration, since the new DCI field can be represented by 1 bit, it is possible to disable multiplexing of LP UCI to HP PUSCH while suppressing an increase in DCI overhead, thereby increasing the reliability of HP PUSCH. can be improved.
　なお、new DCI fieldを含むDCIとしてUL Grant DCIが用いられる場合には、動作例２は、DG PUSCHに適用されてもよい。new DCI fieldを含むDCIとしてDL Grant DCIが用いられる場合には、動作例２は、DG PUSCHに適用されてもよく、CG PUSCHに適用されてもよい。new DCI fieldを含むDCIとしてPUSCH及びPUCCHとは無関係なDCIが用いられる場合には、動作例２は、DG PUSCHに適用されてもよく、CG PUSCHに適用されてもよい。動作例２は、係数（β）が動的に指定されるケース（Dynamic beta-offset）に適用されてもよく、係数（β）が準静的に指定されるケース（Semi-static beta-offset）に適用されてもよい。 Note that when UL Grant DCI is used as the DCI including the new DCI field, operation example 2 may be applied to DG PUSCH. When DL Grant DCI is used as the DCI including the new DCI field, operation example 2 may be applied to DG PUSCH and may be applied to CG PUSCH. When DCI unrelated to PUSCH and PUCCH is used as the DCI including the new DCI field, Operation Example 2 may be applied to DG PUSCH and may be applied to CG PUSCH. Operation example 2 may be applied to the case where the coefficient (β) is dynamically specified (Dynamic beta-offset), or to the case where the coefficient (β) is semi-statically specified (Semi-static beta-offset ) may be applied to
　（４．３）動作例３
　動作例３では、特定DCI（以下、Special DCI）が定義（追加）される。Special DCIは、特定フィールドに格納された情報要素の組合せによって、HP PUSCHに対するLP UCIの多重に関する有効化及び無効化の少なくともいずれか１つを指定する。有効化は、活性化と読み替えられてもよく、無効化は、非活性化と読み替えられてもよい。 (4.3) Operation example 3
In operation example 3, a specific DCI (hereinafter referred to as Special DCI) is defined (added). Special DCI specifies at least one of enabling and disabling multiplexing of LP UCI for HP PUSCH by a combination of information elements stored in a specific field. Validation may be read as activation, and invalidation may be read as deactivation.
　言い換えると、HP PUSCHに対するLP UCIの多重に関する有効化及び無効化の少なくともいずれか１つを明示的又は暗黙的に示す情報要素は、NG RAN20（gNB100）から受信する特定DCI（Special DCI）に含まれる特定フィールドに格納された情報要素の組合せによって構成される第３情報要素であってもよい。 In other words, an information element that explicitly or implicitly indicates at least one of enabling and disabling multiplexing of LP UCI to HP PUSCH is included in the specific DCI (Special DCI) received from NG RAN20 (gNB100). It may be a third information element configured by a combination of information elements stored in the specified field.
　特定DCIのフォーマットとしては、DL DCI Format 1_0、DL DCI Format 1_1、DL DCI Format 1_2、UL DCI Format 0_0、UL DCI Format 0_1及びUL DCI Format 0_2の中から選択された１以上のフォーマットが用いられてもよい。Special DCIは、新たに定義（追加）されるRNTI（例えば、UM（Unacknowledged Mode）-RNTI、UL Multiplexing-RNTI）によってスクランブルされてもよい。 As the specific DCI format, one or more formats selected from DL DCI Format 1_0, DL DCI Format 1_1, DL DCI Format 1_2, UL DCI Format 0_0, UL DCI Format 0_1 and UL DCI Format 0_2 are used. good too. Special DCI may be scrambled by newly defined (added) RNTI (eg, UM (Unacknowledged Mode)-RNTI, UL Multiplexing-RNTI).
　特定フィールドとしては、DCIに含まれるフィールドとして既に定義されたフィールドが用いられてもよい。特定フィールドは、以下に示すフィールドであってもよい。 A field already defined as a field included in DCI may be used as the specific field. The specified fields may be the fields shown below.
　第１に、特定フィールドとしては、RV field、HPN field及びbeta_offset indicator fieldの中から選択された１以上のフィールドが用いられてもよい。例えば、UE200は、RV、HPN及びbeta_offset indicatorの全てが”0”である第１条件が満たされた場合に、HP PUSCHに対するLP UCIの多重を活性化してもよい。或いは、UE200は、第１条件が満たされた場合に、HP PUSCHに対するLP UCIの多重を非活性化してもよい。 First, one or more fields selected from RV field, HPN field, and beta_offset indicator field may be used as the specific field. For example, the UE 200 may activate multiplexing of LP UCI to HP PUSCH when the first condition that RV, HPN and beta_offset indicator are all "0" is satisfied. Alternatively, the UE 200 may deactivate multiplexing of LP UCI to HP PUSCH when the first condition is satisfied.
　第２に、特定フィールドとしては、RV field、HPN field、beta_offset indicator field、MCS field及びFRDA fieldの中から選択された１以上のフィールドが用いられてもよい。例えば、UE200は、RV、HPN及びbeta_offset indicatorの全てが”0”であり、MCSの全てのbitが”1”であり、かつ、μ=0のFRDA Type 2のFRDAの全てのbitが”0”である第２条件が満たされた場合に、HP PUSCHに対するLP UCIの多重を非活性化してもよい。UE200は、RV、HPN及びbeta_offset indicatorの全てが”0”であり、MCSの全てのbitが”1”であり、かつ、μ=0のFRDA Type 2のFRDA以外のFRDAの全てのbitが”1”である第２条件が満たされた場合に、HP PUSCHに対するLP UCIの多重を非活性化してもよい。或いは、UE200は、第２条件が満たされた場合に、HP PUSCHに対するLP UCIの多重を活性化してもよい。 Second, as the specific field, one or more fields selected from RV field, HPN field, beta_offset indicator field, MCS field and FRDA field may be used. For example, UE200 has RV, HPN and beta_offset indicator all "0", all bits of MCS are "1", and all bits of FRDA of FRDA Type 2 with μ=0 are "0" ” may deactivate multiplexing of the LP UCI to the HP PUSCH if the second condition is satisfied. For UE200, RV, HPN and beta_offset indicator are all "0", all bits of MCS are "1", and all bits of FRDA other than FRDA Type 2 with μ=0 are " Multiplexing of LP UCI to HP PUSCH may be deactivated if a second condition of 1" is met. Alternatively, the UE 200 may activate multiplexing of LP UCI to HP PUSCH when the second condition is satisfied.
　すなわち、UE200は、第１条件が満たされた場合に、HP PUSCHに対するLP UCIの多重を活性化し、第２条件が満たされた場合に、HP PUSCHに対するLP UCIの多重を非活性化してもよい。或いは、UE200は、第２条件が満たされた場合に、HP PUSCHに対するLP UCIの多重を活性化し、第１条件が満たされた場合に、HP PUSCHに対するLP UCIの多重を非活性化してもよい。 That is, the UE 200 may activate multiplexing of LP UCI for HP PUSCH when the first condition is satisfied, and deactivate multiplexing of LP UCI for HP PUSCH when the second condition is satisfied. . Alternatively, the UE 200 may activate multiplexing of LP UCI for HP PUSCH when the second condition is satisfied, and deactivate multiplexing of LP UCI for HP PUSCH when the first condition is satisfied. .
　ここで、NG RAN20及びUE200の動作について図１１を参照しながら説明する。図１１では、HP PUSCHに対するLP UCIの多重を有効化するか否かに関する動作について主として説明する。 Here, the operations of the NG RAN 20 and the UE 200 will be explained with reference to FIG. FIG. 11 mainly describes the operation regarding whether to enable multiplexing of LP UCI to HP PUSCH.
　図１１に示すように、ステップS30において、UE200は、UE Capabilityを含むメッセージをNG-RAN20に送信する。UE Capabilityは、Special DCIに対応する機能をUE200が有しているか否かを明示的又は暗黙的に示す情報要素を含んでもよい。 As shown in FIG. 11, in step S30, UE 200 transmits a message including UE Capability to NG-RAN 20. UE Capability may include an information element that explicitly or implicitly indicates whether the UE 200 has the capability to support Special DCI.
　ステップS31において、UE100は、RRCメッセージをNG-RAN20から受信する。RRCメッセージは、same priority multiplexing及びdifferent priority multiplexingの双方に関するUCI-OnPUSCH又はCG UCI-OnPUSCHを含んでもよい。 　In step S31, the UE 100 receives the RRC message from the NG-RAN 20. The RRC message may include UCI-OnPUSCH or CG UCI-OnPUSCH for both same priority multiplexing and different priority multiplexing.
　ステップS32において、UE200は、PDCCHを介してSpecial DCIをNG-RAN20から受信する。Special DCIは、特定フィールドに格納された情報要素の組合せによって構成される第３情報要素（例えば、RV、HPN、beta_offset indicatorなど）を含む。 In step S32, UE 200 receives Special DCI from NG-RAN 20 via PDCCH. Special DCI includes a third information element (eg, RV, HPN, beta_offset indicator, etc.) composed of a combination of information elements stored in specific fields.
　ステップS33において、UE200は、Special DCIに含まれる第３情報要素が第１条件（又は第２条件）を満たす場合に、HP PUSCHに対するLP UCIの多重を有効化する。UE200は、LP UCIをHP PUSCHに多重した上で、HP PUSHを介して上りリンク信号を送信する。一方で、UE200は、Special DCIに含まれる第３情報要素が第２条件（又は第１条件）を満たす場合に、HP PUSCHに対するLP UCIの多重を無効化する。UE200は、LP UCIをHP PUSCHに多重せずに、HP PUSHを介して上りリンク信号を送信する。 In step S33, the UE 200 enables multiplexing of LP UCI to HP PUSCH when the third information element included in Special DCI satisfies the first condition (or second condition). The UE 200 multiplexes the LP UCI to the HP PUSCH and then transmits an uplink signal via the HP PUSH. On the other hand, UE 200 disables multiplexing of LP UCI to HP PUSCH when the third information element included in Special DCI satisfies the second condition (or first condition). UE 200 transmits an uplink signal via HP PUSH without multiplexing LP UCI on HP PUSCH.
　このような構成によれば、追加的なDCI fieldを定義する必要がないため、DCIのオーバヘッドの増大を抑制しながら、HP PUSCHに対するLP UCIの多重を無効化することができ、HP PUSCHの信頼性を向上することができる。 With such a configuration, there is no need to define an additional DCI field, so it is possible to disable multiplexing of LP UCI to HP PUSCH while suppressing an increase in DCI overhead, thereby increasing the reliability of HP PUSCH. can improve sexuality.
　なお、動作例３は、DG PUSCHに適用されてもよく、CG PUSCHに適用されてもよい。動作例３は、係数（β）が動的に指定されるケース（Dynamic beta-offset）に適用されてもよく、係数（β）が準静的に指定されるケース（Semi-static beta-offset）に適用されてもよい。 Note that operation example 3 may be applied to DG PUSCH or may be applied to CG PUSCH. Operation example 3 may be applied to the case where the coefficient (β) is dynamically specified (Dynamic beta-offset), or to the case where the coefficient (β) is semi-statically specified (Semi-static beta-offset ) may be applied to
　（４．４）動作例４
　動作例４では、新たなメッセージ（以下、MAC CE（Control Element）メッセージ）が定義（追加）される。MAC CEメッセージは、HP PUSCHに対するLP UCIの多重に関する活性化及び非活性化の少なくともいずれか１つを指定する。 (4.4) Operation example 4
In operation example 4, a new message (hereinafter referred to as MAC CE (Control Element) message) is defined (added). The MAC CE message specifies at least one of activation and deactivation regarding multiplexing of LP UCI to HP PUSCH.
　言い換えると、HP PUSCHに対するLP UCIの多重に関する有効化及び無効化の少なくともいずれか１つを明示的又は暗黙的に示す情報要素は、NG RAN20（gNB100）から受信するメッセージ（MAC CEメッセージ）に含まれ、HP PUSCHに対するLP UCIの多重の活性化及び非活性化の少なくともいずれか１つを指定する第４情報要素であってもよい。 In other words, an information element that explicitly or implicitly indicates at least one of enabling and disabling multiplexing of LP UCI to HP PUSCH is included in the message (MAC CE message) received from NG RAN20 (gNB100). It may be a fourth information element that specifies at least one of multiple activation and deactivation of LP UCI for HP PUSCH.

The UE 200 may deactivate multiplexing of LP UCI for HP PUSCH when receiving a MAC CE message specifying deactivation of multiplexing of LP UCI for HP PUSCH.
　第２に、HP PUSCHに対するLP UCIの多重の活性化する期間を定義するタイマ（例えば、activation timer）が定義されてもよい。activation timerは、MAC CEメッセージの受信によって起動してもよい。UE200は、activation timerが起動している場合に、HP PUSCHに対するLP UCIの多重を活性化し、activation timerが満了している場合に、HP PUSCHに対するLP UCIの多重を非活性化してもよい。このようなケースにおいて、HP PUSCHに対するLP UCIの多重の非活性化を指定するMAC CEメッセージは定義されなくてもよい。 Second, a timer (eg, activation timer) may be defined that defines multiple activation periods of LP UCI to HP PUSCH. The activation timer may be started upon receipt of a MAC CE message. The UE 200 may activate LP UCI multiplexing for HP PUSCH when the activation timer is activated, and deactivate LP UCI multiplexing for HP PUSCH when the activation timer has expired. In such cases, MAC CE messages specifying multiple deactivations of LP UCI for HP PUSCH may not be defined.
　第３に、HP PUSCHに対するLP UCIの多重の非活性化する期間を定義するタイマ（例えば、deactivation timer）が定義されてもよい。deactivation timerは、MAC CEメッセージの受信によって起動してもよい。UE200は、deactivation timerが起動している場合に、HP PUSCHに対するLP UCIの多重を非活性化し、deactivation timerが満了している場合に、HP PUSCHに対するLP UCIの多重を活性化してもよい。このようなケースにおいて、HP PUSCHに対するLP UCIの多重の活性化を指定するMAC CEメッセージは定義されなくてもよい。 Third, a timer (eg, deactivation timer) may be defined that defines multiple deactivation periods of the LP UCI for the HP PUSCH. A deactivation timer MAY be activated upon receipt of a MAC CE message. The UE 200 may deactivate multiplexing of LP UCI for HP PUSCH when the deactivation timer is activated, and activate multiplexing of LP UCI for HP PUSCH when the deactivation timer has expired. In such cases, MAC CE messages specifying multiple activations of LP UCI for HP PUSCH may not be defined.
　ここで、NG RAN20及びUE200の動作について図１２を参照しながら説明する。図１２では、HP PUSCHに対するLP UCIの多重を有効化するか否かに関する動作について主として説明する。 Here, the operations of the NG RAN 20 and the UE 200 will be explained with reference to FIG. FIG. 12 mainly describes the operation regarding whether to enable multiplexing of LP UCI to HP PUSCH.
　図１２に示すように、ステップS40において、UE200は、UE Capabilityを含むメッセージをNG-RAN20に送信する。UE Capabilityは、MAC CEメッセージに対応する機能をUE200が有しているか否かを明示的又は暗黙的に示す情報要素を含んでもよい。 As shown in FIG. 12, in step S40, UE 200 transmits a message including UE Capability to NG-RAN 20. UE Capability may include an information element that explicitly or implicitly indicates whether the UE 200 has the capability to support MAC CE messages.
　ステップS41において、UE100は、RRCメッセージをNG-RAN20から受信する。RRCメッセージは、same priority multiplexing及びdifferent priority multiplexingの双方に関するUCI-OnPUSCH又はCG UCI-OnPUSCHを含んでもよい。 　In step S41, the UE 100 receives the RRC message from the NG-RAN 20. The RRC message may include UCI-OnPUSCH or CG UCI-OnPUSCH for both same priority multiplexing and different priority multiplexing.
　ステップS42において、UE200は、MAC CEメッセージをNG-RAN20から受信する。MAC CEメッセージは、HP PUSCHに対するLP UCIの多重の活性化及び非活性化の少なくともいずれか１つを指定する第４情報要素を含む。 　In step S42, the UE 200 receives the MAC CE message from the NG-RAN 20. The MAC CE message includes a fourth information element that specifies at least one of multiple activation and deactivation of LP UCI to HP PUSCH.
　ステップS43において、UE200は、MAC CEメッセージが活性化を指定する場合に、activation timerが起動している場合に、或いは、deactivation timerが満了している場合に、HP PUSCHに対するLP UCIの多重を有効化する。UE200は、LP UCIをHP PUSCHに多重した上で、HP PUSHを介して上りリンク信号を送信する。一方で、UE200は、MAC CEメッセージが非活性化を指定する場合に、deactivation timerが起動している場合に、或いは、activation timerが満了している場合に、HP PUSCHに対するLP UCIの多重を無効化する。UE200は、LP UCIをHP PUSCHに多重せずに、HP PUSHを介して上りリンク信号を送信する。 In step S43, the UE 200 enables multiplexing of LP UCI to HP PUSCH when the MAC CE message specifies activation, when the activation timer is running, or when the deactivation timer has expired. become The UE 200 multiplexes the LP UCI to the HP PUSCH and then transmits an uplink signal via the HP PUSH. On the other hand, UE 200 disables multiplexing of LP UCI to HP PUSCH when the MAC CE message specifies deactivation, when the deactivation timer is activated, or when the activation timer expires. become UE 200 transmits an uplink signal via HP PUSH without multiplexing LP UCI on HP PUSCH.
　このような構成によれば、追加的なDCI fieldを定義する必要がないため、DCIのオーバヘッドの増大を抑制しながら、HP PUSCHに対するLP UCIの多重を無効化することができ、HP PUSCHの信頼性を向上することができる。 With such a configuration, there is no need to define an additional DCI field, so it is possible to disable multiplexing of LP UCI to HP PUSCH while suppressing an increase in DCI overhead, thereby increasing the reliability of HP PUSCH. can improve sexuality.

　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、基地局が各ユーザ端末に対して、無線リソース（各ユーザ端末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, 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。 The TTI may be a transmission time unit for channel-encoded data packets (transport blocks), code blocks, codewords, etc., or may be a processing unit for scheduling, link adaptation, etc. 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。 If 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 with 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, etc. A TTI that is shorter than a normal TTI may also 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 so on.
　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。 In addition, long TTI (for example, normal TTI, subframe, etc.) may be read as TTI having a time length exceeding 1 ms, and short TTI (for example, shortened TTI, etc.) is less than the TTI length of long TTI and 1 ms. A TTI having a TTI length greater than or equal to this value may be read as a replacement.
　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、ニューメロロジー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、ニューメロロジー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 frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of neurology, and may be 12, for example. The number of subcarriers included in an RB may be determined based on neumerology.
　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 be configured with one or a plurality of resource blocks.
　なお、１つ又は複数のRBは、物理リソースブロック（Physical RB：PRB）、サブキャリアグループ（Sub-Carrier Group：SCG）、リソースエレメントグループ（Resource Element Group：REG）、PRBペア、RBペアなどと呼ばれてもよい。 One or more RBs are physical resource blocks (PRB), sub-carrier groups (SCG), resource element groups (REG), 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（Resource Element：RE）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 (Resource Element: RE). For example, 1 RE may be a radio resource region of 1 subcarrier and 1 symbol.
　帯域幅部分（Bandwidth Part：BWP）（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ー用の連続する共通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) represents a subset of contiguous common resource blocks (RBs) for a neumerology in a carrier. good. 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。UE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。 BWP may include BWP for UL (UL BWP) and BWP for DL (DL BWP). One or more BWPs may be configured in one carrier for the UE.
　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、UE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 UE 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".
　上述した無線フレーム、サブフレーム、スロット、ミニスロット及びシンボルなどの構造は例示に過ぎない。例えば、無線フレームに含まれるサブフレームの数、サブフレーム又は無線フレームあたりのスロットの数、スロット内に含まれるミニスロットの数、スロット又はミニスロットに含まれるシンボル及びRBの数、RBに含まれるサブキャリアの数、並びにTTI内のシンボル数、シンボル長、サイクリックプレフィックス（Cyclic Prefix：CP）長などの構成は、様々に変更することができる。 The structures such as radio frames, subframes, slots, minislots and symbols described above are only examples. For example, the number of subframes included in a radio frame, the number of slots per subframe or radio frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of Configurations such as the number of subcarriers and the number of symbols in a TTI, symbol length, cyclic prefix (CP) length, etc. can be varied.
