- the time length is set as a scheduling unit of a data channel (including DL data channel and / or UL data channel, also simply referred to as data). It is contemplated to use a changeable time unit (eg, at least one of a slot, a minislot, and a predetermined number of symbols).
- a data channel including DL data channel and / or UL data channel, also simply referred to as data. It is contemplated to use a changeable time unit (eg, at least one of a slot, a minislot, and a predetermined number of symbols).
- the slot is a unit of time based on the neurology (for example, subcarrier interval and / or symbol length) applied by the user terminal.
- the number of symbols per slot may be determined according to the subcarrier interval. For example, when the subcarrier interval is 15 kHz or 30 kHz, the number of symbols per slot may be 7 or 14 symbols. On the other hand, when the subcarrier interval is 60 kHz or more, the number of symbols per slot may be 14 symbols.
- the subcarrier interval and the symbol length are inversely related. For this reason, if the symbols per slot are the same, the slot length becomes shorter as the subcarrier interval becomes higher (wider). On the other hand, the slot length becomes longer as the subcarrier interval becomes lower (narrower).
- the mini slot is a unit of time shorter than the slot.
- a mini-slot may be composed of a smaller number of symbols (for example, 1 to (slot length-1) symbols, for example, 2 or 3 symbols).
- the same neurology (eg, subcarrier spacing and / or symbol length) as the slot may be applied to the minislot within the slot, or a different neurology (eg, higher sub-slot than the slot).
- a carrier interval and / or a symbol length shorter than a slot) may be applied.
- the mini-slot may be composed of 2, 4, or 7 symbols, and may be PDSCH or PUSCH that can flexibly set the start symbol position.
- a PDSCH that is not a minislot may be a PDSCH having a start symbol position of the 0th to 3rd symbols in the slot and having a predetermined symbol length or more.
- a PUSCH that is not a mini-slot may be a PUSCH having a start symbol position of the 0th symbol in the slot and having a predetermined symbol length or longer.
- PDSCH and PUSCH that are not mini-slots may be called PDSCH / PUSCH mapping type A, and PDSCH and PUSCH that are mini-slots may be called PDSCH / PUSCH mapping type B.
- DMRSs may be inserted at different positions according to the PDSCH / PUSCH mapping type.

- a slot can be composed of, for example, 7 symbols or 14 symbols
- a minislot can be composed of 1 to (slot length-1) symbols.
- FIG. 1 shows a case where PUSCH is scheduled over K slots.
- PUCCH multi-slot scheduling is being studied for PUCCH. For example, when scheduling is performed in slot units, PUCCH is allocated to a plurality of slots.
- a configuration in which PUCCH is assigned to a plurality of slots is also referred to as PUCCH multi-slot scheduling or PUCCH multi-slot transmission.
- the configuration (format, PUCCH format (PF), etc.) for the uplink control channel (for example, PUCCH) used for UCI transmission is also used.
- PUCCH uplink control channel
- LTE Rel. 15 it is considered to support five types of PF0 to PF4.
- the name of PF shown below is only an illustration and a different name may be used.
- PF 0 and 1 are PFs used for transmission of UCI (for example, acknowledgment information (HARQ-ACK: Hybrid Automatic Repeat reQuest-Acknowledge, ACK or NACK)) of 2 bits or less (up to 2 bits). Since PF0 can be assigned to 1 or 2 symbols, it is also referred to as short PUCCH or sequence-based short PUCCH, etc. On the other hand, since PF1 can be assigned to 4-14 symbols, long PUCCH In PF1, the same resource block (physical resource) is obtained by time domain block spreading using at least one of cyclic shift (CS) and orthogonal spreading code (for example, OCC (Orthogonal Cover Code)). Multiple users within a block (PRB: Physical Resource Block)
- the terminal may be code division multiplexed (CDM).
- PF2-4 transmits more than 2 bits (more than 2 bits) UCI (for example, channel state information (CSI) (or CSI and HARQ-ACK and / or scheduling request (SR))) PF used. Since PF2 can be assigned to one or two symbols, it is also called a short PUCCH or the like. On the other hand, since PFs 3 and 4 can be assigned to 4-14 symbols, they are also called long PUCCHs. In PF4, a plurality of user terminals may be CDM using block spreading in the (frequency domain) before DFT.
- UCI for example, channel state information (CSI) (or CSI and HARQ-ACK and / or scheduling request (SR)
- PF2 can be assigned to one or two symbols, it is also called a short PUCCH or the like.
- PFs 3 and 4 can be assigned to 4-14 symbols, they are also called long PUCCHs.
- a plurality of user terminals may be CDM using block spreading in the (frequency domain) before DFT.
- Allocation of resources (for example, PUCCH resources) used for transmission of the uplink control channel is performed using higher layer signaling and / or downlink control information (DCI).
- the higher layer signaling is, for example, at least one of RRC (Radio Resource Control) signaling, system information (for example, RMSI: Remaining Minimum System Information, OSI: Other system information, MIB: Master Information Block, SIB: System Information Block).
- RRC Radio Resource Control
- system information for example, RMSI: Remaining Minimum System Information
- OSI Remaining Minimum System Information
- MIB Master Information Block
- SIB System Information Block
- broadcast information PBCH: Physical Broadcast Channel.
- UCI for example, A / N
- the base station specifies the UCI transmission timing / transmission period to the UE using downlink control information and / or higher layer signaling.
- the A / N feedback timing is flexibly set in a period after the downlink control information for notifying the transmission timing / transmission period of the A / N and / or the corresponding PDSCH.
- UCI transmission and UL data (UL-SCH) transmission occur at the same timing, UCI and UL data are multiplexed and transmitted on PUSCH (UCI). piggyback on PUSCH and UCI on PUSCH).
- TDD time division duplex
- TDD time division duplex
- uplink and downlink are time division multiplexed in the same frequency band.
- DL / UL allocation configuration can be set semi-statically by cell-specific (that is, a channel commonly received by UEs in the cell) or UE-specific higher layer signaling.
- the special subframe is divided into three parts: a downlink part (DwPTS: downlink pilot time slot), a guard interval (GP), and an uplink part (UpPTS: uplink pilot time slot).
- DwPTS downlink pilot time slot
- GP guard interval
- UpPTS uplink pilot time slot
- the “subframe” may be read as “slot”.
- TDD and multi-slot scheduling are applied to a wireless communication system, the following rules (regulations, conditions, and restrictions on operation in user terminals) are being studied.
- Kc is 4 or more
- slot # 0 the start slot.
- Values that can be set as Kc are 1, 2, 4, and 8.
- the value of Kc is set by RRC signaling.
- PUCCH transmission can be performed in the Kc slot section after slot # 0 (for example, when all Kc slots are UL slots)
- the user terminal starts PUCCH transmission symbols in slot # 0, the number of symbols, the PRB position, the PUCCH format, etc. Are transmitted in slot # 0.
- multi-slot transmission is performed in the Kc slot section using the same start symbol, number of symbols, PUCCH format, and the like as slot # 0.
- the PRB positions after slot # 1 can change depending on the presence of frequency hopping and its setting. That is, when frequency hopping between slots is set, PUCCH transmission is performed in slot # 1 using a PRB different from slot # 0.
- uplink transmission is allocated to slots # 0, # 1, # 4, and # 5 in time-sequential slots # 0 to # 5. It has been.
- Slot # 2 is assigned downlink transmission.
- Slot # 3 is set as a special slot (the above-mentioned special subframe is replaced with a special slot).
- PUCCH transmission uplink transmission started from slot # 0 is continued until slot # 1. Thereafter, PUCCH transmission is not performed in slot # 2 to which downlink transmission is assigned. In slot # 3 corresponding to the special slot, when at least a part of the PUCCH transmission symbols set in the slot is a DL symbol in the slot, PUCCH transmission is not performed. Then, PUCCH transmission suspended in slot # 2 is resumed in slots # 4 and # 5.
- a slot to which uplink transmission is not assigned (a slot to which downlink transmission is assigned) or at least a part of a PUCCH transmission symbol set in the slot is UL in the slot. Even if the transmission of PUCCH is interrupted by being set as a symbol that cannot be transmitted (for example, DL symbol), the transmission of PUCCH is resumed in the slot where the subsequent PUCCH transmission is possible, and the specified Kc The PUCCH for the slot is transmitted.
- Kd is 3 or more
- the values that can be set as Kd are 1, 2, 4, and 8.
- the value of Kd is set by RRC signaling.
- the user terminal After slot # 0, when PUSCH transmission can be performed in the Kd slot section (for example, when all the Kd slots are UL slots), the user terminal starts PUSCH transmission symbols, number of symbols, PRB position, and transport block in slot # 0. The size, modulation scheme, DMRS pattern, etc. are determined, and transmission is performed in slot # 0. Further, multi-slot transmission is performed in the Kd slot section using the same start symbol, number of symbols, transport block size, modulation scheme, DMRS pattern, and the like as slot # 0.
- the PRB positions after slot # 1 can change depending on the presence of frequency hopping and its setting. That is, when frequency hopping between slots is set, PUSCH transmission is performed in slot # 1 using a PRB different from slot # 0.
- the DL / UL allocation configuration is the same as in the case of the above-described PUCCH, and a description thereof will be omitted.
- PUSCH transmission In PUSCH transmission, uplink transmission started from slot # 0 is continued until slot # 1. Thereafter, since downlink transmission is assigned to slot # 2, uplink transmission cannot be performed, and continuous PUSCH transmission is interrupted. In PUSCH transmission, when continuous transmission is interrupted in this way, subsequent PUSCH transmission is not performed (cancelled) at that time. For example, PUSCH transmission is not resumed in slot # 4 to which uplink transmission is assigned.
- PUCCH transmission and PUSCH transmission in TDD are different (ruled) in terms of user terminal operations. For this reason, some considerations occur when performing UCI on PUSCH in TDD (see FIG. 3).
- transmission may be interrupted by a slot to which uplink transmission is assigned (for example, slot # 2 in FIG. 3).
- the inventors of the present application control UCI on PUSCH based on at least one of the DL / UL allocation configuration and the relationship between consecutive slots of PUCCH and PUSCH specified by multi-slot scheduling. I was inspired by that. Thereby, even if TDD and multi-slot scheduling are applied, UCI on PUSCH can be appropriately performed.

- a plurality of arrangement relationships (case 1-6) shown in FIGS. 4 and 5 can be considered.
- Slot configuration 1 shows a configuration in which the PUCCH transmission period is included in the PUSCH transmission period. That is, the disclosure position of PUCCH (start position on the time axis (time domain)) is later than the start position of PUSCH, and the end position of PUCCH (end position on the time axis (time domain)) is greater than the end position of PUSCH. Too early.
- Slot configurations 2 and 3 show a configuration in which a PUCCH transmission period and a PUSCH transmission period partially overlap.
- the disclosure position of PUCCH is later than the start position of PUSCH, and the end position of PUCCH is later than the end position of PUSCH.
- slot configuration 3 the disclosure position of PUCCH is earlier than the start position of PUSCH, and the end position of PUCCH is earlier than the end position of PUSCH.
- Slot configuration 4 shows a configuration in which the PUCCH transmission period includes the PUSCH transmission period. That is, the PUCCH disclosure position is earlier than the PUSCH start position, and the PUCCH end position is later than the PUSCH end position.
- Slot configuration 5 shows a configuration in which the transmission period of PUCCH and the transmission period of PUSCH (including a reference signal) are set to be the same. That is, the PUCCH disclosure position and the PUSCH start position are equal, and the PUCCH end position and the PUSCH end position are equal.
- Slot configuration 6 shows a case where the transmission period of PUCCH and the transmission period of PUSCH (including a reference signal) are set so as not to overlap. That is, PUCCH and PUSCH are orthogonal.

(If not). That is, the multi-slot PUCCH / PUSCH transmission is not interrupted by a slot to which uplink transmission is not assigned (a slot to which downlink transmission is assigned or a special slot). In such a case, UCI on PUSCH is performed in all slots for Kc. Specifically, as shown in FIG. 6, UCI on PUSCH is performed in slots # 0 to # 3.
- UCI mapping pattern and UL data rate matching and puncture control in UCI on PUSCH may be common to all slots constituting the multi-slot.
- case 1-2 a case will be described in which there are slots (or special slots) to which downlink transmission is allocated in the DL / UL allocation configuration for Kc slots from the start position. That is, multi-slot PUCCH / PUSCH transmission is interrupted by a slot (or special slot) to which downlink transmission is assigned. In such a case, the following two controls (options) can be considered.
- the rules for PUSCH multi-slot scheduling are applied to PUCCH multi-slot scheduling.
- PUSCH multi-slot scheduling when PUSCH transmission is interrupted by a slot to which uplink transmission is not assigned (a slot to which downlink transmission is assigned or a special slot), the subsequent PUSCH transmission is canceled. .
- PUCCH multi-slot scheduling Such rules also apply to PUCCH multi-slot scheduling. For this reason, when PUCCH transmission is interrupted by a slot to which uplink transmission is not assigned (a slot to which downlink transmission is assigned or a special slot), subsequent PUCCH transmission is canceled. On the other hand, UCI on PUSCH is performed in a slot before the PUSCH transmission is interrupted and in which the PUSCH and the PUCCH are scheduled simultaneously.
- UCI on PUSCH is performed in slots # 0 and # 1.
- PUCCH transmission is not performed even in slots # 4 and # 5 to which uplink transmission is allocated after interruption of PUCCH / PUSCH transmission.
- slots # 4 and # 5 PUSCH is not transmitted.

- UCI on PUSCH is performed in slots # 0 and # 1.
- PUSCH transmission is not performed in slots # 4 and # 5 to which uplink transmission is allocated after PUCCH / PUSCH transmission is interrupted.
- PUCCH transmission is performed in slots # 4 and # 5. In this way, the number of UCI transmission slots can be ensured regardless of whether UCI on PUSCH is applied, and UCI quality can be improved.
- transmission of uplink data and uplink control information (UCI on PUSCH) using the uplink shared channel is performed even when the data channel and / or the control channel are flexibly scheduled. Can be done appropriately.
- UCI on PUSCH can be appropriately performed even when time division duplex (TDD) and multi-slot scheduling are applied.
- the scheduling may be performed by the radio base station (gNB), and the following control may be performed by the user terminal.
- gNB radio base station
- PUCCH / PUSCH can be transmitted in all slots to which multi-slot PUCCH / PUSCH is assigned. For example, even when the DL / UL allocation configuration is set, if all slots to which multi-slot PUCCH / PUSCH are allocated are uplink slots (the designated multi-slot is a slot other than uplink transmission). Etc.). That is, multi-slot PUCCH / PUSCH transmission is not interrupted by the DL / UL allocation configuration.
- Case 2-1 is further classified. In this case, it is assumed that the end slots of PUCCH and PUSCH coincide (see FIG. 9). In such case 2-1a, the following control (option) can be considered.
- This option cancels (drops) the transmission started first among the PUCCH transmission and the PUSCH transmission, and only the transmission started later is performed.
- PUCCH transmission is canceled and only PUSCH transmission is performed.
- the transmission started first is canceled as much as possible or the transmission data is dropped at the user terminal. By doing so, it becomes possible to control new scheduling information with priority over old scheduling information in time, so that a low-delay service can be appropriately realized.
- Case 2-1 is further classified.
- the start position (start slot) of the scheduled PUCCH multislot is ahead of the start position of the PUSCH as in the previous case 2-1 a, but the end of the PUCCH Assume that the slot is earlier than the end slot of PUSCH (see FIG. 10).
- the following control (option) can be considered.
- UCI on PUSCH is performed in a slot where PUCCH and PUSCH overlap.

Abstract
Description
第1の態様では、マルチスロットスケジューリングにおいて、PUCCHについて指定されたスロット数(Kc)と、PUSCHについて指定されたスロット数(Kd)とが等しく、かつ、開始位置(マルチスロットの最初のスロット)がPUCCHとPUSCHで一致している場合の制御について説明する。
ケース1-1では、上記開始位置からのKc分のスロットが、DL/UL割り当て構成において、全て上りリンク送信が割り当てられている場合(Kc分のスロットに上りリンク送信以外のスロットが含まれていない場合)について説明する。すなわち、上りリンク伝送が割り当てられていないスロット(下りリンク伝送が割り当てられたスロット又は特別スロット)によって、マルチスロットのPUCCH/PUSCH送信が中断されることがない。このような場合、Kc分の全てのスロットにおいて、UCI on PUSCHが行われる。具体的には、図6に示されるようにスロット#0-#3におて、UCI on PUSCHが行われる。
ケース1-2では、上記開始位置からのKc分のスロットが、DL/UL割り当て構成において、下りリンク送信が割り当てられたスロット(又は特別スロット)が存在する場合について説明する。すなわち、下りリンク送信が割り当てられたスロット(又は特別スロット)によって、マルチスロットのPUCCH/PUSCH送信が中断される。このような場合、以下の2つの制御(オプション)が考えられる。
このオプションでは、PUSCHのマルチスロットスケジューリングにおけるルールが、PUCCHのマルチスロットスケジューリングに適用される。上述のように、PUSCHのマルチスロットスケジューリングでは、上りリンク伝送が割り当てられていないスロット(下りリンク伝送が割り当てられたスロット又は特別スロット)によりPUSCH送信を中断した場合、以降のPUSCH送信はキャンセルされる。
このオプションでは、PUCCHのマルチスロットスケジューリングのルールと、PUSCHのマルチスロットスケジューリングのルールの双方が維持される。さらに、PUSCH送信が中断される前のスロットであって、PUSCH及びPUCCHが同時にスケジューリングされているスロットではUCI on PUSCHが行われる。
第2の態様では、マルチスロットスケジューリングにおいて、PUCCHについて指定されたスロット数(Kc)と、PUSCHについて指定されたスロット数(Kd)とが異なる場合、及び/又は、開始位置(マルチスロットの最初のスロット)がPUCCHとPUSCHで一致していない場合の制御について説明する。
このケースでは、マルチスロットのPUCCH/PUSCHが割り当てられた全てのスロットで、PUCCH/PUSCHを送信できる場合について説明する。これは例えば、DL/UL割り当て構成が設定された場合でも、マルチスロットのPUCCH/PUSCHが割り当てられた全てのスロットが、上りリンクスロットである場合(指定されたマルチスロットに上りリンク送信以外のスロットが含まれていない場合)などである。すなわち、マルチスロットのPUCCH/PUSCH送信が、DL/UL割り当て構成によって中断されることがない。
ケース2-1はさらに分類される。このケースでは、PUCCH及びPUSCHの終了スロットは一致しているものとする(図9参照)。このようなケース2-1aでは、以下の制御(オプション)が考えられる。
このオプションでは、PUCCHとPUSCHとが重複するスロットにおいて、UCI on PUSCHが行われる。重複しないスロット、すなわち、PUCCHの送信のみが指定されているスロットについては、PUCCHのみの送信が行われる。このようにすることで、UCIの送信開始時間とULデータの送信開始時間を維持しつつ両者を送信することができるため、端末処理負担増加を抑圧することができる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信についてのみ行われ、後から開始される送信はキャンセルする。上記図9においては、PUCCH送信のみが行われ、PUSCH送信はキャンセルされる。このようにすることで、端末はUCI送信開始以降PUSCHの送信処理をする必要がなくなることから、端末処理負担を軽減することができる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信をキャンセル(ドロップ)し、後から開始される送信のみが行われる。上記図9においては、PUCCH送信がキャンセルされ、PUSCH送信のみが行われる。なお、先に開始された送信については、ユーザ端末において、可能な限りキャンセル、又は、送信データのドロップが行われる。このようにすることで、時間的に新しいスケジューリング情報を古いスケジューリング情報よりも優先して制御することができるようになるため、低遅延サービスを適切に実現することができる。
ケース2-1はさらに分類される。このケース2-1bでは、スケジューリングされたPUCCHのマルチスロットの開始位置(開始スロット)が、PUSCHの開始位置よりも先であることは、先のケース2-1aと同様であるが、PUCCHの終了スロットがPUSCHの終了スロットよりも早いものとする(図10参照)。このようなケース2-1bでは、以下の制御(オプション)が考えられる。
このオプションでは、PUCCHとPUSCHとが重複するスロットにおいて、UCI on PUSCHが行われる。重複しないスロット、すなわち、PUCCHの送信のみが指定されているスロット、及び、PUSCH送信のみが指定されているスロットについては、それぞれの送信が行われる。
このオプションでは、全てのスロットでUCI on PUSCHが行われる。なお、PUCCHとPUSCHとが重複していないスロットについては、重複しているスロットのUCI又は上りデータをコピーして、UCI on PUSCHが行われる。このようにすることで、マルチスロットのPUSCHに対してスロット間で同様にUCI on PUSCHを適用することができるため(すなわちスロットごとに違うマッピングを適用することがないため)、端末処理負担を軽減できる。また、UCIの送信回数を増加できるので、UCIの品質確保も容易となる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信についてのみ行われ、後から開始される送信はキャンセル、又は、重複しないスロットにおいてのみ送信が行われる。具体的には、PUCCH送信のみが行われ、PUSCH送信はキャンセルされる。もしくは、PUCCHのみが指定されているスロット、及び、PUCCH及びPUSCHが重複して指定されているスロット、ではPUCCH送信のみが行われ、さらに、PUSCHのみが指定されているスロットでは、PUSCH送信のみが行われる。このようにすることで、UCIとULデータの両方を送信する機会を設けることができる。また、UCI on PUSCH制御は行わないため、端末処理負担を軽減することができる。
このオプションでは、PUCCH送信とPUSCH送信との内、後に開始された送信についてのみ行われ、先に開始される送信はキャンセル、又は、重複しないスロットにおいてのみ送信が行われる。具体的には、PUSCH送信のみが行われ、PUCCH送信はキャンセルされる。もしくは、PUSCHのみが指定されているスロット、及び、PUCCH及びPUSCHが重複して指定されているスロット、ではPUSCH送信のみが行われ、さらに、PUCCHのみが指定されているスロットでは、PUCCH送信のみが行われる。このようにすることで、時間的に新しいスケジューリング情報を古いスケジューリング情報よりも優先して制御することができるようになるため、低遅延サービスを適切に実現することができる。
ケース2-1はさらに分類される。このケース2-1cでは、スケジューリングされたPUCCHのマルチスロットの開始位置(開始スロット)が、PUSCHの開始位置よりも先であることは、先のケース2-1a、2-1bと同様であるが、PUSCHの終了スロットがPUCCHの終了スロットよりも早いものとする(図11参照)。このようなケース2-1cでは、以下の制御(オプション)が考えられる。
このオプションでは、PUCCHとPUSCHとが重複するスロットにおいて、UCI on PUSCHが行われる。重複しないスロット、すなわち、PUCCHの送信のみが指定されているスロットについては、PUCCHのみの送信が行われる。このようにすることで、UCIの繰り返し回数を確保し、UCIの品質を改善することができる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信についてのみ行われ、後から開始される送信はキャンセルする。上記図11においては、PUCCH送信のみが行われ、PUSCH送信はキャンセルされる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信についてのみ行われ、後から開始される送信はキャンセル、又は、重複しないスロットにおいてのみ送信が行われる。具体的には、PUCCH送信のみが行われ、PUSCH送信はキャンセルされる。もしくは、PUCCHのみが指定されているスロット、及び、PUCCH及びPUSCHが重複して指定されているスロット、ではPUCCH送信のみが行われ、さらに、PUSCHのみが指定されているスロットでは、PUSCH送信のみが行われる。このようにすることで、ユーザ端末は後の送信を考慮する必要がなくなることから、端末処理負担を軽減することができる。
このケースでは、全てのスロットが、DL/UL割り当て構成において、全て上りリンク送信が割り当てられている場合(指定されたマルチスロットに上りリンク送信以外のスロットが含まれていない場合)であることは、ケース2-1と同じである。すなわち、上りリンク伝送が割り当てられていないスロット(下りリンク伝送が割り当てられたスロット又は特別スロット)によって、マルチスロットのPUCCH/PUSCH送信が中断されることがない。
ケース2-2はさらに分類される。このケースでは、PUCCH及びPUSCHの終了スロットは一致しているものとする(図12参照)。このようなケース2-2aでは、以下の制御(オプション)が考えられる。
このオプションでは、PUCCHとPUSCHとが重複するスロットにおいて、UCI on PUSCHが行われる。重複しないスロット、すなわち、PUSCHの送信のみが指定されているスロットについては、PUSCHのみの送信が行われる。このようにすることで、UCIの送信開始タイミングとULデータの送信開始タイミングを変更することなく両者を適切な回数送信することができるため、端末処理負担増加を抑圧しつつ品質を確保することができる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信についてのみ行われ、後から開始される送信はキャンセルする。上記図12においては、PUSCH送信のみが行われ、PUCCH送信はキャンセルされる。このようにすることで、ユーザ端末は後の送信を考慮する必要がなくなることから、端末処理負担を軽減することができる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信をキャンセル(ドロップ)し、後から開始される送信のみが行われる。上記図12においては、PUSCH送信がキャンセルされ、PUCCH送信のみが行われる。なお、先に開始された送信については、ユーザ端末において、可能な限りキャンセル、又は、送信データのドロップが行われる。このようにすることで、時間的に新しいスケジューリング情報を古いスケジューリング情報よりも優先して制御することができるようになるため、低遅延サービスを適切に実現することができる。

このオプションでは、PUCCHとPUSCHとが重複するスロットにおいて、UCI on PUSCHが行われる。重複しないスロット、すなわち、PUCCHの送信のみが指定されているスロット、及び、PUSCH送信のみが指定されているスロットについては、それぞれの送信が行われる。このようにすることで、UCIの送信開始時間とULデータの送信開始時間を維持しつつ両者を送信することができるため、端末処理負担増加を抑圧することができる。
このオプションでは、重複する最初のスロットから、PUSCHが指定された最後のスロットまで、UCI on PUSCHが行われる。なお、PUCCHとPUSCHとが重複していないスロットについては、重複しているスロットのUCI又はULデータをコピーして、UCI on PUSCHが行われる。このようにすることで、マルチスロットのPUSCHに対してスロット間で同様にUCI on PUSCHを適用することができるため(すなわちスロットごとに違うマッピングを適用することがないため)、端末処理負担を軽減できる。また、UCIの送信回数を増加できるので、UCIの品質確保も容易となる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信についてのみ行われ、後から開始される送信はキャンセル、又は、重複しないスロットにおいてのみ送信が行われる。具体的には、PUSCH送信のみが行われ、PUCCH送信はキャンセルされる。もしくは、PUSCHのみが指定されているスロット、及び、PUCCH及びPUSCHが重複して指定されているスロット、ではPUSCH送信のみが行われ、さらに、PUCCHのみが指定されているスロットでは、PUCCH送信のみが行われる。このようにすることで、端末処理負担を軽減しつつ、UCIとULデータの送信スロット数を維持することができる。
このオプションでは、PUCCH送信とPUSCH送信との内、後に開始された送信についてのみ行われ、先に開始される送信はキャンセル、又は、重複しないスロットにおいてのみ送信が行われる。具体的には、PUCCH送信のみが行われ、PUSCH送信はキャンセルされる。もしくは、PUCCHのみが指定されているスロット、及び、PUCCH及びPUSCHが重複して指定されているスロット、ではPUCCH送信のみが行われ、さらに、PUSCHのみが指定されているスロットでは、PUSCH送信のみが行われる。このようにすることで、時間的に新しいスケジューリング情報を古いスケジューリング情報よりも優先して制御することができるようになるため、低遅延サービスを適切に実現することができる。
ケース2-2はさらに分類される。このケース2-2cでは、スケジューリングされたPUCCHのマルチスロットの開始位置(開始スロット)が、PUSCHの開始位置よりも先であることは、先のケース2-2a、2-2bと同様であるが、PUSCHの終了スロットがPUCCHの終了スロットよりも早いものとする(図14参照)。このようなケース2-2cでは、以下の制御(オプション)が考えられる。
このオプションでは、PUCCHとPUSCHとが重複するスロットにおいて、UCI on PUSCHが行われる。重複しないスロット、すなわち、PUCCHの送信のみが指定されているスロットについては、PUCCHのみの送信が行われる。このようにすることで、UCIとULデータの両方について、送信スロット数を維持し、品質を確保することができる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信についてのみ行われ、後から開始される送信はキャンセルする。上記図14においては、PUSCH送信のみが行われ、PUCCH送信はキャンセルされる。このようにすることで、端末は後の送信を考慮する必要がなくなることから、端末処理負担を軽減することができる。
このオプションでは、PUCCH送信とPUSCH送信との内、先に開始された送信についてのみ行われ、後から開始される送信はキャンセル、又は、重複しないスロットにおいてのみ送信が行われる。具体的には、PUCCH送信のみが行われ、PUSCH送信はキャンセルされる。もしくは、PUCCHのみが指定されているスロット、及び、PUCCH及びPUSCHが重複して指定されているスロット、ではPUCCH送信のみが行われ、さらに、PUSCHのみが指定されているスロットでは、PUSCH送信のみが行われる。このようにすることで、端端末処理負担を軽減しつつも、UCIとULデータ両者を少なくとも1スロットで送信することができる。
このケースでは、DL/UL割り当て構成において、下りリンク送信が割り当てられたスロット(又は特別スロット)が存在する場合について説明する。すなわち、下りリンク送信が割り当てられたスロット(又は特別スロット)によって、マルチスロットのPUCCH/PUSCH送信が中断される。このような場合、以下の2つの制御(オプション)が考えられる。
このオプションでは、PUSCHのマルチスロットスケジューリングにおけるルールが、PUCCHのマルチスロットスケジューリングに適用される。上述のように、PUSCHのマルチスロットスケジューリングでは、上りリンク伝送が割り当てられていないスロット(下りリンク伝送が割り当てられたスロット又は特別スロット)によりPUSCH送信を中断した場合、以降のPUSCH送信はキャンセルされる。
このオプションでは、PUCCHのマルチスロットスケジューリングのルールと、PUSCHのマルチスロットスケジューリングのルールの双方が維持される。さらに、PUSCH送信が中断される前のスロットであって、PUSCH及びPUCCHが同時にスケジューリングされているスロットではUCI on PUSCHが行われる。
次に第3の態様について説明する。ここでは、ロングPUCCHとミニスロット型PUSCHとの衝突(重複)について説明する。図15は、1スロットの構成が示されている。1スロット内に複数のミニスロット型のPUSCH(ショートPUSCH)が、繰り返しで配置されている。具体的には、kd=1~kd=4まで、シートPUSCHの繰り返しが4回設定されている。
このオプションでは、PUCCH(ロングPUCCH)の送信をキャンセル(ドロップ)する。これにより、予め設定されていたショートPUSCHの繰り返しを維持することができ、かつ端末処理負担の増加を抑圧できる。
このオプションでは、ロングPUCCHとショートPUSCHとが重複している部分(期間)では、PUSCHを送信しない。具体的には、kd=3、4では、PUSCHが送信されない。このようにすることで、のちにスケジューリングされた新しい情報を優先的に送信することができ、低遅延データや低遅延UCIを優先的に送信することができるようになる。
このオプションでは、ロングPUCCHとショートPUSCHとが重複している部分(期間)で、UCI on PUSCHを行う。
以下、本実施の形態に係る無線通信システムの構成について説明する。この無線通信システムでは、上記各態様に係る無線通信方法が適用される。なお、上記各態様に係る無線通信方法は、それぞれ単独で適用されてもよいし、少なくとも2つを組み合わせて適用されてもよい。
図19は、本実施の形態に係る無線基地局の全体構成の一例を示す図である。無線基地局10は、複数の送受信アンテナ101と、アンプ部102と、送受信部103と、ベースバンド信号処理部104と、呼処理部105と、伝送路インターフェース106とを備えている。なお、送受信アンテナ101、アンプ部102、送受信部103は、それぞれ1つ以上を含むように構成されてもよい。
図21は、本実施の形態に係るユーザ端末の全体構成の一例を示す図である。ユーザ端末20は、MIMO伝送のための複数の送受信アンテナ201と、アンプ部202と、送受信部203と、ベースバンド信号処理部204と、アプリケーション部205と、を備えている。
なお、上記実施形態の説明に用いたブロック図は、機能単位のブロックを示している。これらの機能ブロック(構成部)は、ハードウェア及び/又はソフトウェアの任意の組み合わせによって実現される。また、各機能ブロックの実現方法は特に限定されない。すなわち、各機能ブロックは、物理的及び/又は論理的に結合した1つの装置を用いて実現されてもよいし、物理的及び/又は論理的に分離した2つ以上の装置を直接的及び/又は間接的に(例えば、有線及び/又は無線を用いて)接続し、これら複数の装置を用いて実現されてもよい。
なお、本明細書において説明した用語及び/又は本明細書の理解に必要な用語については、同一の又は類似する意味を有する用語と置き換えてもよい。例えば、チャネル及び/又はシンボルは信号(シグナリング)であってもよい。また、信号はメッセージであってもよい。参照信号は、RS(Reference Signal)と略称することもでき、適用される標準によってパイロット(Pilot)、パイロット信号などと呼ばれてもよい。また、コンポーネントキャリア(CC:Component Carrier)は、セル、周波数キャリア、キャリア周波数などと呼ばれてもよい。
