As shown in FIG. 4, when the PUCCH and the N PUSCHs overlap in the time domain, which PUSCH the operation shown in the above A1) -A3) is applied is hereinafter A'1)-. The terminal 20 may be determined by the rule shown in A'4). The rule is applied in both cases of CA (Carrier Aggregation) and non-CA. In the case of CA, the processing for overlap is limited to CCs of the same PUCCH group. That is, it is assumed that the PUCCH and the N PUSCHs are in the same PUCCH group CC.

The terminal 20 cannot skip the PUSCH determined to multiplex the UCI, and always transmits it. The MAC layer generates a MAC PDU for the PUSCH determined to multiplex the UCI. In C1), there is no prioritization of LCH, and a single PHY priority is assumed. It may be assumed that there is no PUSCH repeated transmission.
Ｃ２）ＣＧ－ＰＵＳＣＨの場合、すべてのＰＵＳＣＨを送信するものと想定し、いずれのＰＵＳＣＨにＵＣＩを多重するかを端末２０は決定する。端末２０は、ＵＣＩを多重すると決定されたＰＵＳＣＨをスキップすることはできず、必ず送信する。ＵＣＩを多重すると決定されたＰＵＳＣＨに対して、ＭＡＣレイヤはＭＡＣ　ＰＤＵを生成する。なお、Ｃ２）ではＬＣＨの優先順位付けはなく、単一のＰＨＹ優先度、ＰＵＳＣＨ繰り返し送信なしを想定する。 C2) In the case of CG-PUSCH, it is assumed that all PUSCHs are transmitted, and the terminal 20 determines to which PUSCH the UCI is to be multiplexed.

Do not start transmission in the middle of repeated transmission opportunities. In other cases, for example, when "startingFromRV0-r16" is set to "on", transmission can be started from the repeated transmission opportunity associated with RV (RedundancyVersion) = 0. For example, when the RV sequence is {0,2,3,1}, transmission can be started from the beginning of the repeated transmission opportunity. Further, for example, when the RV sequence is {0,3,0,3}, transmission can be started from the odd-numbered number of repeated transmission opportunities, for example, the beginning and the third. Further, for example, when the RV sequence is {0,0,0,0}, transmission can be started from any transmission opportunity of the repeated transmission opportunity.

When the terminal 20 detects that the transmission opportunity of the second PUSCH from the front in the time domain overlaps with the PUCCH in the time domain among the four transmission opportunities shown in the example of FIG. 6, FIG. It may be determined that the UCI of the PUCCH cannot be included in the PUSCH of the second transmission opportunity because the PUSCH is not transmitted at the first transmission opportunity for the time of the example.

　図７は、ＵＬチャネルがオーバラップする例（５）を示す図である。図７は、繰り返し送信が設定されたＣＧ－ＰＵＳＣＨの複数の送信機会のうちのある送信機会とＰＵＣＣＨとが時間領域において重複した例を示す。図７の例では、時間方向において、前の方から４つのＰＵＳＣＨの送信機会が設定されている。時間方向において前の方から２番目のＰＵＳＣＨの送信機会は時間領域においてＰＵＣＣＨと重複している。例えば、端末２０は、当該ＰＵＣＣＨと時間領域において重複した送信機会が繰り返し送信の時間に関して最初の送信機会ではないと判定する。端末２０は、図７の例に示される４つの送信機会のうち、時間に関して最初の送信機会ではＰＵＳＣＨの送信を行わなかったとする。この場合において、端末２０は、図７の例に示される４つの送信機会のうち、時間方向において前の方から２番目のＰＵＳＣＨの送信機会においてＰＵＳＣＨの送信を行わなくてもよい。その後、時間方向において３番目及び４番目の送信機会において、端末２０は、ＰＵＳＣＨの送信を行わなくてもよい。 FIG. 7 is a diagram showing an example (5) in which UL channels overlap. FIG. 7 shows an example in which a certain transmission opportunity among a plurality of transmission opportunities of the CG-PUSCH set to be repeatedly transmitted and the PUCCH overlap in the time domain. In the example of FIG. 7, four PUSCH transmission opportunities are set from the front in the time direction. The transmission opportunity of the second PUSCH from the front in the time domain overlaps with the PUCCH in the time domain. For example, the terminal 20 determines that the transmission opportunity that overlaps with the PUCCH in the time domain is not the first transmission opportunity with respect to the time of repeated transmission. It is assumed that the terminal 20 does not transmit the PUSCH at the first transmission opportunity in terms of time among the four transmission opportunities shown in the example of FIG. In this case, the terminal 20 does not have to transmit the PUSCH at the transmission opportunity of the second PUSCH from the front in the time direction among the four transmission opportunities shown in the example of FIG. After that, at the third and fourth transmission opportunities in the time direction, the terminal 20 does not have to transmit the PUSCH.

The PUCCH may be transmitted by dropping the PUSCH of the transmission opportunity without generating the PUCCH, or if there is another PUSCH, the PUSCH may be multiplexed with the other PUSCH.
　当該送信機会で、送信すべきデータが存在する場合であっても、当該送信機会のＰＵＳＣＨはドロップされてもよく、後続の送信機会は当該データを送信してもよい。 Even if there is data to be transmitted at the transmission opportunity, the PUSCH of the transmission opportunity may be dropped, and the data may be transmitted at the subsequent transmission opportunity.
　上述のＨ１）－Ｈ４）に示される例では、ＣＧ－ＰＵＳＣＨの繰り返し送信の場合に、複数のＰＵＳＣＨの送信機会のうちのいずれかの送信機会がＰＵＣＣＨと時間領域において重複した場合の端末２０の動作例が説明されている。しかしながら、実施例は、ＣＧ－ＰＵＳＣＨの繰り返し送信の場合に限定されず、ＤＧ－ＰＵＳＣＨの繰り返し送信の場合に適用されてもよい。 In the example shown in H1) -H4) above, in the case of repeated transmission of CG-PUSCH, in the case of the transmission opportunity of one of a plurality of PUSCHs, the transmission opportunity of the terminal 20 overlaps with the PUCCH in the time domain. An example of operation is explained. However, the embodiment is not limited to the case of repeated transmission of CG-PUSCH, and may be applied to the case of repeated transmission of DG-PUSCH.
　ＤＧ－ＰＵＳＣＨの繰り返し送信の場合、端末２０は、全てのＰＵＳＣＨの送信をスキップしてもよく、あるいは全てのＰＵＳＣＨの送信を行ってもよい。 In the case of repeated transmission of DG-PUSCH, the terminal 20 may skip the transmission of all PUSCHs, or may transmit all PUSCHs.
　ＤＧ－ＰＵＳＣＨの繰り返し送信の場合において、複数のＰＵＳＣＨの送信機会のうち、時間方向において途中の送信機会から送信してもよいか否か、時間方向において後続の送信機会の扱いをどうするかについて、上述の実施例を適用することが可能である。 In the case of repeated transmission of DG-PUSCH, whether or not transmission may be performed from an intermediate transmission opportunity in the time direction among the transmission opportunities of a plurality of PUSCHs, and how to handle the subsequent transmission opportunity in the time direction. It is possible to apply the above embodiment.
　図５－図７において、ＣＧ－ＰＵＳＣＨの繰り返し送信がスロット単位で行われている例が示されているが、本実施例は、この例には限定されない。例えば、ＣＧ－ＰＵＳＣＨの繰り返し送信は、シンボル単位で行われてもよい。なお、ＣＧ－ＰＵＳＣＨの繰り返し送信がスロット単位で行われる場合をＰＵＳＣＨ　ｒｅｐｅｔｉｔｉｏｎ　ｔｙｐｅ　Ａと呼び、ＣＧ－ＰＵＳＣＨの繰り返し送信がシンボル単位で行われる場合をＰＵＳＣＨ　ｒｅｐｅｔｉｔｉｏｎ　ｔｙｐｅ　Ｂと呼んでもよい。 5 to 7 show an example in which CG-PUSCH is repeatedly transmitted in slot units, but this embodiment is not limited to this example. For example, repeated transmission of CG-PUSCH may be performed in symbol units. The case where the repeated transmission of CG-PUSCH is performed in slot units may be referred to as PUSCH reproduction type A, and the case where the repeated transmission of CG-PUSCH is performed in symbol units may be referred to as PUSCH repetition type B.
　ＰＵＳＣＨ　ｒｅｐｅｔｉｔｉｏｎ　ｔｙｐｅ　Ｂにおいて、ｉｎｖａｌｉｄ　ｓｙｍｂｏｌにｙほってｎｏｍｉｎａｌ　ｒｅｐｅｔｉｔｉｏｎから複数のａｃｔｕａｌ　ｒｅｐｅｔｉｔｉｏｎが決定された場合、当該ａｃｔｕａｌ　ｒｅｐｅｔｉｔｉｏｎに対して上述のＨ１）－Ｈ４）に示される例を適用してもよい。 In the PUSCH representation type B, when a plurality of actual repitations are determined from the negative symbol y, the example shown in H1) -H4) above may be applied to the actual repitation.
　上述のＨ１）－Ｈ４）に示される例は、繰り返し送信を行わないＰＵＣＣＨのみを対象としてもよく、繰り返し送信を行うＰＵＣＣＨを対象としてもよい。 The example shown in H1) -H4) above may target only the PUCCH that does not repeatedly transmit, or may target the PUCCH that repeatedly transmits.
　なお、上述の繰り返し送信は、同じトランスポートブロック（すなわち、ＭＡＣ　ＰＤＵ）の繰り返し送信を意味してもよい。 Note that the above-mentioned repeated transmission may mean repeated transmission of the same transport block (that is, MAC PDU).
　上述のＨ１）－Ｈ４）に示される例によれば、ＰＵＣＣＨと複数のＰＵＳＣＨのうちのいずれかのＰＵＳＣＨとが少なくとも時間領域で重複する場合のうちの特定のケースにおいて、端末２０が、ＰＵＣＣＨのＵＣＩをＰＵＳＣＨに含める動作及びＰＵＳＣＨの送信をスキップする動作が明確化される。端末２０が、ＰＵＣＣＨのＵＣＩをＰＵＳＣＨに含める動作については、ＰＵＳＣＨの繰り返し送信無しの場合と同じ動作にすることができる。また、端末２０が、ＰＵＣＣＨのＵＣＩをＰＵＳＣＨに含ない動作については、不要な（あるいは追加の機能を必要とする）ＰＵＳＣＨ送信を回避できる。 According to the example shown in H1) -H4) above, in a specific case where the PUCCH and the PUSCH of any of the plurality of PUSCHs overlap at least in the time domain, the terminal 20 is the PUCCH. The operation of including the UCI in the PUSCH and the operation of skipping the transmission of the PUSCH are clarified. The operation of the terminal 20 including the UCI of the PUCCH in the PUSCH can be the same as the operation without the repeated transmission of the PUSCH. Further, for the operation in which the terminal 20 does not include the UCI of the PUCCH in the PUSCH, it is possible to avoid unnecessary (or additional functions) PUSCH transmission.
　ここで、上記Ａ、Ａ′、Ｂ、Ｃ、Ｄ、Ｅ、Ｆ及びＧの条件のうち複数が同時に満たされる場合の端末２０の動作が明確ではなかった。例えば、１以上のＰＵＳＣＨ送信が設定又は指示され、少なくとも一つのＰＵＳＣＨに繰り返し送信が設定又は指示され、いずれかのＰＵＳＣＨとＰＵＣＣＨとが少なくとも時間領域でオーバラップし、少なくとも一つのＰＵＳＣＨリソースで送信すべきデータがなく、ＰＵＳＣＨのスキップが可能であり、論理チャネルの優先度及び／又は物理レイヤにおける優先度が設定又は指示される場合の端末２０の動作が規定されていなかった。 Here, the operation of the terminal 20 when a plurality of the above conditions A, A', B, C, D, E, F and G are satisfied at the same time is not clear. For example, one or more PUSCH transmissions are set or instructed, at least one PUSCH is set or instructed to repeatedly transmit, and either PUSCH and PUCCH overlap at least in the time domain and are transmitted by at least one PUSCH resource. There was no data to be written, PUSCH could be skipped, and the operation of the terminal 20 when the priority of the logical channel and / or the priority in the physical layer was set or instructed was not specified.
　そこで、所定の条件が満たされた場合、所定の方法でＰＵＳＣＨとＰＵＣＣＨのオーバラップを解決してもよい。なお、以下、優先度の記載について、高い優先順位をＨＰ（Higher priority）、低い優先順位をＬＰ（Lower priority）と記載する。ＨＰ及びＬＰは、物理レイヤにおける優先度であってもよく、例えば論理チャネルのような上位レイヤにおける優先度であってもよい。優先順位が３以上ある場合、優先順位を２グループに分けて優先度が高いグループをＨＰ、優先度が低いグループをＬＰとしてもよい。 Therefore, if a predetermined condition is satisfied, the overlap between PUSCH and PUCCH may be resolved by a predetermined method. Hereinafter, regarding the description of the priority, the high priority is described as HP (Higher priority) and the low priority is described as LP (Lower priority). HP and LP may be priorities in the physical layer, or may be priorities in higher layers such as logical channels. When the priority is 3 or more, the priority may be divided into two groups, the group with high priority may be referred to as HP, and the group with low priority may be referred to as LP.
　例えば、上記所定の条件は、以下１）－５）に示される条件であってもよい。 For example, the above-mentioned predetermined conditions may be the conditions shown in 1) -5) below.
１）１以上のＰＵＳＣＨ送信が設定又は指示される場合。
２）少なくとも一つのＰＵＳＣＨに繰り返し送信が設定又は指示される場合。
３）いずれかのＰＵＳＣＨとＰＵＣＣＨとが少なくとも時間領域でオーバラップする場合。
４）少なくとも一つのＰＵＳＣＨリソースで送信すべきデータがなく、当該ＰＵＳＣＨ送信のスキップが可能である場合。上記Ｂ１）又はＢ２）に示されるルールに基づいてＰＵＳＣＨ送信がスキップできる場合であってもよい。
５）論理チャネルの優先度及び／又は物理レイヤにおける優先度が設定又は指示される場合。 1) When one or more PUSCH transmissions are set or instructed.
2) When repeated transmission is set or instructed to at least one PUSCH.
3) When either PUSCH and PUCCH overlap at least in the time domain.
4) When there is no data to be transmitted by at least one PUSCH resource and the PUSCH transmission can be skipped. It may be the case that the PUSCH transmission can be skipped based on the rule shown in B1) or B2) above.
5) When the priority of the logical channel and / or the priority in the physical layer is set or specified.
　例えば、上記所定の方法は、以下提案１）－提案３）に示される方法であってもよい。 For example, the above-mentioned predetermined method may be the method shown in Proposal 1) -Proposal 3) below.
提案１）優先度ごとにチャネル間のオーバラップを処理した後、異なる優先度を有するチャネル間のオーバラップを処理する。
提案２）高い優先度を有するチャネルに係るオーバラップを処理した後、処理後の高い優先度を有するチャネルに基づいて、低い優先度を有するチャネルに係るオーバラップを処理する。
提案３）高い優先度を有するチャネルにオーバラップする低い優先度を有するチャネルをドロップした後、優先度ごとにチャネル間のオーバラップを処理する。 Proposal 1) After processing the overlap between channels for each priority, handle the overlap between channels with different priorities.
Proposal 2) After processing the overlap related to the channel having high priority, the overlap related to the channel having low priority is processed based on the channel having high priority after processing.
Proposal 3) Overlapping to a channel with a high priority After dropping a channel with a low priority, the overlap between the channels is processed for each priority.

As in the above proposal 1), the terminal 20 may process the overlap between channels having different priorities after processing the overlap between channels for each priority. That is, if there is no data to be transmitted in the PUSCH repeated transmission, the PUSCH transmission at the transmission opportunity can be skipped, and the PUCCHs of the same priority overlap at a certain transmission opportunity, the solution is to use channels of different priorities. It does not have to be related to overlap. For example, when PUCCHs having the same priority overlap, the terminal 20 may solve the problem by the method shown in H1) -H4) above.
　ステップＳ１１において、端末２０は、優先度ごとにチャネル間のオーバラップを処理する。続くステップＳ１２において、端末２０は、異なる優先度を有するチャネル間のオーバラップを処理する。ステップＳ１２において、以下１）－４）に示される方法で、異なる優先度を有するチャネル間のオーバラップを解決してもよい。 In step S11, the terminal 20 processes the overlap between channels for each priority. In a subsequent step S12, the terminal 20 handles the overlap between channels having different priorities. In step S12, the overlap between channels having different priorities may be resolved by the method shown in 1) -4) below.
１）送信されることが確定しているＨＰチャネル（例えば、ＰＵＣＣＨ、ＵＣＩを伴うＰＵＳＣＨ、スキップが許可されていないＤＧ－ＰＵＳＣＨ等）と、ＬＰチャネルのオーバラップに対して、ＨＰチャネルを優先してＬＰチャネルをドロップしてもよい。 1) Priority is given to HP channels for overlap between HP channels that are confirmed to be transmitted (for example, PUCCH, PUSCH with UCI, DG-PUSCH that is not allowed to skip, etc.) and LP channels. You may drop the LP channel.
２）スキップされ得るＰＵＳＣＨ－ＨＰと、ＬＰチャネルとのオーバラップとに対して、ＰＵＳＣＨ－ＨＰにＭＡＣ　ＰＤＵを生成し、オーバラップするＬＰチャネルはドロップしてもよい。すなわち、ＰＵＳＣＨが繰り返し送信であるか否か、データがあるか否か、繰り返し送信のうち送信開始可能な送信機会であるか否か、には依存しなくてもよい。 2) For the overlap between the PUSCH-HP that can be skipped and the LP channel, a MAC PDU is generated in the PUSCH-HP, and the overlapping LP channel may be dropped. That is, it does not have to depend on whether or not the PUSCH is a repetitive transmission, whether or not there is data, and whether or not the repetitive transmission is a transmission opportunity at which transmission can be started.
３）スキップされ得るＰＵＳＣＨ－ＨＰと、ＬＰチャネルとのオーバラップとに対して、ＰＵＳＣＨ－ＨＰにＭＡＣ　ＰＤＵを生成しなくてもよい。すなわち、ＰＵＳＣＨが繰り返し送信であるか否か、データがあるか否か、繰り返し送信のうち送信開始可能な送信機会であるか否か、には依存しなくてもよい。 3) It is not necessary to generate a MAC PDU in the PUSCH-HP for the overlap between the PUSCH-HP that can be skipped and the LP channel. That is, it does not have to depend on whether or not the PUSCH is a repetitive transmission, whether or not there is data, and whether or not the repetitive transmission is a transmission opportunity at which transmission can be started.
４）スキップされ得るＰＵＳＣＨ－ＨＰと、ＬＰチャネルとのオーバラップとに対して、スキップされ得るＰＵＳＣＨ－ＨＰと、ＬＰチャネルとのオーバラップとに対して、ＰＵＳＣＨが繰り返し送信であるか否か、データがあるか否か、繰り返し送信のうち送信開始可能な送信機会であるか否か、の少なくとも一つに基づいて、処理を決定してもよい。例えば、ＰＵＳＣＨ－ＨＰの繰り返し送信である場合、ＰＵＳＣＨ－ＨＰにＭＡＣ　ＰＤＵを生成せず、ＰＵＳＣＨ－ＨＰの繰り返し送信でない場合、ＰＵＳＣＨ－ＨＰにＭＡＣ　ＰＤＵを生成してもよい。例えば、ＰＵＳＣＨ－ＨＰの繰り返し送信であって送信開始可能な送信機会ではない場合、ＰＵＳＣＨ－ＨＰにＭＡＣ　ＰＤＵを生成せず、送信開始可能な送信機会である場合、ＰＵＳＣＨ－ＨＰにＭＡＣ　ＰＤＵを生成してもよい。 4) Whether or not the PUSCH is repeatedly transmitted with respect to the overlap between the PUSCH-HP which can be skipped and the LP channel and the overlap between the PUSCH-HP which can be skipped and the LP channel. The process may be determined based on at least one of whether or not there is data and whether or not it is a transmission opportunity that can start transmission among repeated transmissions. For example, in the case of repeated transmission of PUSCH-HP, MAC PDU may not be generated in PUSCH-HP, and in the case of repeated transmission of PUSCH-HP, MAC PDU may be generated in PUSCH-HP. For example, if it is a repeated transmission of PUSCH-HP and it is not a transmission opportunity that can start transmission, a MAC PDU is not generated in PUSCH-HP, and if it is a transmission opportunity that can start transmission, a MAC PDU is generated in PUSCH-HP.

１）ステップＳ２１処理後のＰＵＣＣＨ－ＨＰ／ＰＵＳＣＨ－ＨＰで送信が確定したチャネルがＰＵＣＣＨ－ＬＰ／ＰＵＳＣＨ－ＬＰにオーバラップしている場合、当該ＰＵＣＣＨ－ＬＰ／ＰＵＳＣＨ－ＬＰを除いたチャネルでＬＰチャネルのオーバラップを解決してもよい。ＰＵＳＣＨ－ＬＰの繰り返し送信が含まれる場合、上記Ｈ１）－Ｈ４）の方法を適用してもよい。また、除かれるチャネルはＰＵＳＣＨ－ＬＰに限定されてもよい。また、ＬＰチャネルのオーバラップ解決後に、ＨＰチャネルとオーバラップするＬＰチャネルはドロップされてもよい。 1) When the channel whose transmission is confirmed by PUCCH-HP / PUSCH-HP after the step S21 processing overlaps with PUCCH-LP / PUSCH-LP, LP is performed on the channel excluding the PUCCH-LP / PUSCH-LP. Channel overlap may be resolved. When the repeated transmission of PUSCH-LP is included, the method of H1) -H4) may be applied. Further, the channel to be excluded may be limited to PUSCH-LP. Further, the LP channel that overlaps with the HP channel may be dropped after the overlap of the LP channel is resolved.
２）ステップＳ２１処理後のＰＵＣＣＨ－ＨＰ／ＰＵＳＣＨ－ＨＰで送信が確定したチャネルがＰＵＣＣＨ－ＬＰ／ＰＵＳＣＨ－ＬＰにオーバラップしている場合、さらに、オーバラップしているＬＰチャネルに、ＨＰチャネルとオーバラップしないＰＵＳＣＨ－ＬＰがある場合（例えば図１２のケース）、当該ＰＵＳＣＨ－ＬＰについて、ＰＵＳＣＨが繰り返し送信であるか否か、データがあるか否か、繰り返し送信のうち送信開始可能な送信機会であるか否か、の少なくとも一つに基づいて、処理を決定してもよい。 2) When the channel whose transmission is confirmed by PUCCH-HP / PUSCH-HP after the step S21 processing overlaps with PUCCH-LP / PUSCH-LP, the overlapping LP channel is further combined with the HP channel. When there is a PUSCH-LP that does not overlap (for example, in the case of FIG. 12), whether or not the PUSCH is repeatedly transmitted, whether or not there is data, and a transmission opportunity that can start transmission among the repeated transmissions.
