Description

Method, device and system for generating feedback information

technical field

本申请涉及通信领域。This application relates to the field of communications.

Background technique

为了提高HARQ-ACK(Hybrid Automatic Repeat Request-ACK，混合自动重传请求确认)反馈的可靠性，NR(New Radio，新无线)引入半静态的类型一码本(type I codebook)。这种码本的长度是根据RRC(Radio Resource Control，无线资源控制)信令预先确定的，这样的好处是可以避免由于用户设备(UE)漏检PDCCH(Physical Downlink Control Channel，物理下行控制信道)而导致的码本生成错误。In order to improve the reliability of HARQ-ACK (Hybrid Automatic Repeat Request-ACK, hybrid automatic repeat request confirmation) feedback, NR (New Radio, new wireless) introduces a semi-static type I codebook. The length of this codebook is pre-determined according to RRC (Radio Resource Control, radio resource control) signaling. resulting in codebook generation errors.

在现有技术中，当承载HARQ-ACK信息的PUCCH(Physical Uplink Control Channel，物理上行控制信道)对应的时域资源与PUSCH(Physical Uplink Shared Channel，物理上行共享信道)对应的时域资源重叠时，该PUCCH不会被发送，相应的原本由该PUCCH承载的HARQ-ACK信息将由PUSCH承载。如果上述的HARQ-ACK信息对应的是type I codebook，为了保证UE能够有足够的时间生成相应的HARQ-ACK比特，UE不在PDSCH#1对应的HARQ-ACK比特生成ACK(positive acknowledgement，确认)，而是直接设为NACK(Negative acknowledgement，否认)。In the prior art, when the time domain resources corresponding to the PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) carrying HARQ-ACK information overlap with the time domain resources corresponding to the PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) , the PUCCH will not be sent, and the corresponding HARQ-ACK information originally carried by the PUCCH will be carried by the PUSCH. If the above HARQ-ACK information corresponds to the type I codebook, in order to ensure that the UE has enough time to generate the corresponding HARQ-ACK bits, the UE does not generate ACK (positive acknowledgment, confirmation) for the HARQ-ACK bits corresponding to PDSCH#1, Instead, it is directly set to NACK (Negative acknowledgment, denial).

以图1为例，图1是PDCCH监测机会的一个示例的示意图，示出了调度PDSCH的PDCCH对应的PDCCH监测机会(PO#2)的起始晚于调度PUSCH的PDCCH对应的PDCCH监测机会(PO#1)的情况。如图1所示，UE在PO#1(PDCCH monitoring occasion#1)中检测到PDCCH#1，或者说，PDCCH#1对应的PDCCH监测机会(monitoring occasion)为PO#1，PDCCH#1调度PUSCH#1；UE在PO#2(PDCCH monitoring occasion#1)中检测到PDCCH#2，或者说，PDCCH#2对应的PDCCH监测机会为PO#2，PDCCH#2调度PDSCH#1；根据PDCCH#2中包含的指示信息，承载PDSCH#1的HARQ-ACK信息的PUCCH#1与该PUSCH#1在时域上重叠。由于PO#2的起始时间晚于PO#1，为了确保UE有足够的时间生成HARQ-ACK信息并填充至PUSCH#1，在PUSCH#1上承载的类型1的HARQ-ACK码书(Type 1 HARQ-ACK codebook)中对应于PDSCH#1的HARQ-ACK信息比特会被置为NACK。由于type 1 HARQ-ACK codebook所有信息比特的默认值都为NACK。因此，这意味着，UE无需根据是否成功接收PDSCH#1而生成PDSCH#1所对应的HARQ-ACK信息。或者说，无论UE是否成功接收PDSCH#1，PUSCH#1中所承载的type 1 HARQ-ACK codebook中与PDSCH#1对应的HARQ-ACK信息被UE设置为NACK。这样UE在生成PUSCH中的type 1 HARQ-ACK codebook时，无需考虑PDSCH#1是否成功接收，以便保证UE有足够的时间生成相应的信息。Taking FIG. 1 as an example, FIG. 1 is a schematic diagram of an example of a PDCCH monitoring opportunity, which shows that the start of the PDCCH monitoring opportunity (PO#2) corresponding to the PDCCH scheduling PDSCH is later than the PDCCH monitoring opportunity corresponding to the PDCCH scheduling PUSCH ( PO#1) case. As shown in Figure 1, the UE detects PDCCH#1 in PO#1 (PDCCH monitoring occasion#1), or in other words, the PDCCH monitoring occasion (monitoring occasion) corresponding to PDCCH#1 is PO#1, and PDCCH#1 schedules PUSCH #1; UE detects PDCCH#2 in PO#2 (PDCCH monitoring occasion#1), or in other words, the PDCCH monitoring opportunity corresponding to PDCCH#2 is PO#2, and PDCCH#2 schedules PDSCH#1; according to PDCCH#2 The indication information included in the PUCCH #1 carrying the HARQ-ACK information of the PDSCH #1 overlaps with the PUSCH #1 in the time domain. Since the start time of PO#2 is later than that of PO#1, in order to ensure that the UE has enough time to generate HARQ-ACK information and fill it into PUSCH#1, the type 1 HARQ-ACK codebook (Type 1) carried on PUSCH#1 1 HARQ-ACK codebook) The HARQ-ACK information bits corresponding to PDSCH#1 will be set to NACK. Since the default value of all information bits in the type 1 HARQ-ACK codebook is NACK. Therefore, this means that the UE does not need to generate HARQ-ACK information corresponding to PDSCH#1 according to whether PDSCH#1 is successfully received. In other words, regardless of whether the UE successfully receives PDSCH#1, the HARQ-ACK information corresponding to PDSCH#1 in the type 1 HARQ-ACK codebook carried in PUSCH#1 is set as NACK by the UE. In this way, when the UE generates the type 1 HARQ-ACK codebook in the PUSCH, it does not need to consider whether PDSCH#1 is successfully received, so as to ensure that the UE has enough time to generate corresponding information.

以图2为例，图2是PDCCH监测机会的另一个示例的示意图，示出了调度PDSCH的PDCCH对应的PDCCH监测机会(PO#2)早于调度PUSCH的PDCCH对应的PDCCH监测机会(PO#1)的情况。如图2所示，PDCCH#1调度PUSCH#1，PDCCH#1对应的PDCCH监测机会为PO#1，或者说，UE在PO#1中检测到PDCCH#1；PDCCH#2调度PDSCH#1，PDCCH#2对应的PDCCH监测机会为PO#2，或者说，UE在PO#2中检测到PDCCH#2；根据PDCCH#1中包含的指示信息，承载该PDSCH的HARQ-ACK信息的PUCCH#1与该PUSCH#1在时域上重叠。由于PO#2的起始时间早于PO#1，UE有足够的时间生成HARQ-ACK信息并填充至PUSCH#1，因此在PUSCH#1上承载的对应于PDSCH#1的HARQ-ACK信息比特即为ACK。Taking FIG. 2 as an example, FIG. 2 is a schematic diagram of another example of a PDCCH monitoring opportunity, which shows that the PDCCH monitoring opportunity (PO#2) corresponding to the PDCCH scheduling PDSCH is earlier than the PDCCH monitoring opportunity (PO#2) corresponding to the PDCCH scheduling PUSCH 1) Situation. As shown in Figure 2, PDCCH#1 schedules PUSCH#1, and the PDCCH monitoring opportunity corresponding to PDCCH#1 is PO#1. In other words, the UE detects PDCCH#1 in PO#1; PDCCH#2 schedules PDSCH#1, The PDCCH monitoring opportunity corresponding to PDCCH#2 is PO#2, or the UE detects PDCCH#2 in PO#2; according to the indication information contained in PDCCH#1, PUCCH#1 carrying the HARQ-ACK information of the PDSCH It overlaps with this PUSCH #1 in the time domain. Since the start time of PO#2 is earlier than PO#1, UE has enough time to generate HARQ-ACK information and fill it into PUSCH#1, so the HARQ-ACK information bits corresponding to PDSCH#1 carried on PUSCH#1 That is ACK.

发明内容Contents of the invention

发明人发现，在上述type 1 HARQ-ACK codebook在PUSCH中发送的情况下，UE是否处理相应的PDSCH(例如，PDSCH#1)是根据相应的PDCCH监测机会确定的。当引入了多TRP PDCCH的情况下，一个PDCCH对应两个PDCCH候选(candidate)，而这两个PDCCH候选所对应的PDCCH监测机会有可能不同，如图3所示，图3是PDCCH监测机会的再一个示例的示意图，示出了用于调度PUSCH的PDCCH对应两个不同的PDCCH监测机会(PO#1，PO#2)，并且，用于调度PDSCH的PDCCH也对应两个不同的PDCCH监测机会(PO#3，PO#4)的情况。具体的说，PUSCH对应的PDCCH对应两个不同的PDCCH监测机会和/或PDSCH对应的PDCCH对应两个不同PDCCH监测机会的情况下，如果不做进一步的规定，根据现有的方法，由于不确定哪个PDCCH监测机会可以作为参考PDCCH监测机会，UE无法确定哪些PDSCH需要处理(例如，需要反馈ACK)，哪些PDSCH无需额外处理(例如，按照默认值设置为NACK)。The inventors found that, in the case that the above type 1 HARQ-ACK codebook is sent in the PUSCH, whether the UE processes the corresponding PDSCH (for example, PDSCH#1) is determined according to the corresponding PDCCH monitoring opportunity. When multiple TRP PDCCHs are introduced, one PDCCH corresponds to two PDCCH candidates (candidates), and the PDCCH monitoring opportunities corresponding to the two PDCCH candidates may be different, as shown in Figure 3, Figure 3 is the PDCCH monitoring opportunity A schematic diagram of another example shows that the PDCCH used to schedule the PUSCH corresponds to two different PDCCH monitoring opportunities (PO#1, PO#2), and the PDCCH used to schedule the PDSCH also corresponds to two different PDCCH monitoring opportunities (PO#3, PO#4) case. Specifically, if the PDCCH corresponding to the PUSCH corresponds to two different PDCCH monitoring opportunities and/or the PDCCH corresponding to the PDSCH corresponds to two different PDCCH monitoring opportunities, if no further provisions are made, according to the existing method, due to uncertain Which PDCCH monitoring opportunity can be used as a reference PDCCH monitoring opportunity, and the UE cannot determine which PDSCHs need to be processed (for example, ACK needs to be fed back) and which PDSCHs do not require additional processing (for example, set as NACK by default).

在本申请实施例中，第一信息对应两个PDCCH监听机会是指：终端设备在两个PDCCH监听机会接收该第一信息。同理，第一DCI对应两个PDCCH监测机会是指：终端设备在两个PDCCH监测机会接收该第一DCI。In this embodiment of the present application, the fact that the first information corresponds to two PDCCH monitoring opportunities means that the terminal device receives the first information in two PDCCH monitoring opportunities. Similarly, the fact that the first DCI corresponds to two PDCCH monitoring opportunities means that the terminal device receives the first DCI in two PDCCH monitoring opportunities.

在一些实施例中，第一信息用于指示用于承载所述PDSCH对应的HARQ-ACK信息的PUCCH的时域位置，并且，该PUCCH与前述PUSCH在时域上重叠。也即，如果原本用于承载PDSCH对应的HARQ-ACK信息的PUCCH与前述PUSCH在时域上重叠，则终端设备不发送该PUCCH，而原本由PUCCH所承载的PDSCH对应的HARQ-ACK信息由该PUSCH承载。In some embodiments, the first information is used to indicate the time domain position of the PUCCH used to carry the HARQ-ACK information corresponding to the PDSCH, and the PUCCH overlaps with the aforementioned PUSCH in the time domain. That is, if the PUCCH originally used to carry the HARQ-ACK information corresponding to the PDSCH overlaps with the aforementioned PUSCH in the time domain, the terminal device does not send the PUCCH, and the HARQ-ACK information corresponding to the PDSCH originally carried by the PUCCH is determined by the PUCCH. PUSCH bearer.

例如，该第一信息为另一个DCI(称为第二DCI)，该第二DCI调度了上述PDSCH并且指示了承载该PDSCH的HARQ-ACK信息的PUCCH的时域位置。一般来说，该PDSCH对应的HARQ-ACK信息原本在上述PUCCH上承载，但是，由于该PUCCH与前述PUSCH在时域上重叠，则终端设备不再发送PUCCH，而该PDSCH对应的HARQ-ACK信息通过上述PUSCH承载并传输。For example, the first information is another DCI (called second DCI), and the second DCI schedules the PDSCH and indicates the time domain position of the PUCCH carrying the HARQ-ACK information of the PDSCH. Generally speaking, the HARQ-ACK information corresponding to the PDSCH is originally carried on the above-mentioned PUCCH. However, since the PUCCH overlaps with the aforementioned PUSCH in the time domain, the terminal device no longer sends the PUCCH, and the HARQ-ACK information corresponding to the PDSCH Carried and transmitted through the above PUSCH.

在本申请实施例中，PUSCH中包含的HARQ-ACK码本为类型1的HARQ-ACK码本(type 1 HARQ-ACK codebook)。In the embodiment of the present application, the HARQ-ACK codebook included in the PUSCH is a type 1 HARQ-ACK codebook (type 1 HARQ-ACK codebook).

在本申请实施例中，第一PDCCH监测机会晚于第二PDCCH监测机会是指：第一PDCCH监测机会的起始符号不早于第二PDCCH监测机会的结束符号。In this embodiment of the present application, the fact that the first PDCCH monitoring opportunity is later than the second PDCCH monitoring opportunity means that the start symbol of the first PDCCH monitoring opportunity is not earlier than the end symbol of the second PDCCH monitoring opportunity.

在一些实施例中，第一PDCCH监测机会是指，上述第一信息对应的两个PDCCH监测机会中较晚一个。In some embodiments, the first PDCCH monitoring opportunity refers to the later one of the two PDCCH monitoring opportunities corresponding to the above first information.

例如，该第一PDCCH监测机会是指，上述第一信息对应的两个PDCCH监测机会中起始符号较晚的一个，或者结束符号较晚的一个。For example, the first PDCCH monitoring opportunity refers to the one with a later start symbol or the later end symbol among the two PDCCH monitoring opportunities corresponding to the above first information.

在一些实施例中，第一PDCCH监测机会是指，上述第一信息对应的两个PDCCH监测机会中较早一个。In some embodiments, the first PDCCH monitoring opportunity refers to the earlier one of the two PDCCH monitoring opportunities corresponding to the above first information.

例如，该第一PDCCH监测机会是指，上述第一信息对应的两个PDCCH监测机会中起始符号较早的一个，或者结束符号较早的一个。For example, the first PDCCH monitoring opportunity refers to the one with the earlier start symbol or the earlier end symbol among the two PDCCH monitoring opportunities corresponding to the first information.

在一些实施例中，第二PDCCH监测机会是指，上述第一DCI对应的两个PDCCH监测机会中较晚的一个。In some embodiments, the second PDCCH monitoring opportunity refers to the later one of the two PDCCH monitoring opportunities corresponding to the first DCI.

例如，该第二PDCCH监测机会是指，上述第一DCI对应的两个PDCCH监测机会中起始符号较晚的一个，或者结束符号较晚的一个。For example, the second PDCCH monitoring opportunity refers to the one with a later start symbol or the later end symbol among the two PDCCH monitoring opportunities corresponding to the first DCI.

在一些实施例中，第二PDCCH监测机会是指，上述第一DCI对应的两个PDCCH监测机会中较早的一个。In some embodiments, the second PDCCH monitoring opportunity refers to the earlier one of the two PDCCH monitoring opportunities corresponding to the first DCI.

例如，该第二PDCCH监测机会是指，上述第一DCI对应的两个PDCCH监测机会中起始符号较早的一个，或者结束符号较早的一个。For example, the second PDCCH monitoring opportunity refers to the one with the earlier start symbol or the earlier end symbol among the two PDCCH monitoring opportunities corresponding to the first DCI.

下面结合具体的示例对本申请实施例的方法进行说明。The method in the embodiment of the present application will be described below with reference to specific examples.

在一些实施例中，如前所述，第一DCI对应两个PDCCH监测机会，并且，第一信息也对应两个PDCCH监测机会。In some embodiments, as mentioned above, the first DCI corresponds to two PDCCH monitoring opportunities, and the first information also corresponds to two PDCCH monitoring opportunities.

图5是PDCCH监测机会的一个示例的示意图，示出了第二PDCCH监测机会为第一DCI对应的两个PDCCH监测机会中较晚的一个，并且，第一PDCCH监测机会为第一信息对应的两个PDCCH监测机会中较早的一个的情况。5 is a schematic diagram of an example of a PDCCH monitoring opportunity, showing that the second PDCCH monitoring opportunity is the later one of the two PDCCH monitoring opportunities corresponding to the first DCI, and the first PDCCH monitoring opportunity is the one corresponding to the first information. The case of the earlier of the two PDCCH monitoring opportunities.

如图5所示，UE检测到基站的指示信息，该指示信息指示UE反馈type 1 HARQ-ACK codebook。本申请对上述指示信息不做限制。As shown in Figure 5, the UE detects the indication information from the base station, and the indication information instructs the UE to feed back a type 1 HARQ-ACK codebook. This application does not limit the above instruction information.

此外，UE检测到DCI format#1，该DCI格式用于调度PUSCH#1，并且，该DCI格式对应PDCCH#1和PDCCH#2，其中，PDCCH#1和PDCCH#2对应相同的DCI比特；PDCCH#1是指在PO#1中的PDCCH候选；PDCCH#2是指在PO#2中的PDCCH候选。In addition, the UE detects DCI format#1, which is used to schedule PUSCH#1, and the DCI format corresponds to PDCCH#1 and PDCCH#2, where PDCCH#1 and PDCCH#2 correspond to the same DCI bit; PDCCH #1 refers to the PDCCH candidate in PO#1; PDCCH#2 refers to the PDCCH candidate in PO#2.

此外，UE检测到DCI format#2，该DCI格式用于调度PDSCH#1，并且，该DCI格式指示PDSCH#1的HARQ-ACK信息所在的位置，也即，承载Type 1 HARQ-ACK codebook的PUCCH#1的位置。此外，该DCI格式对应PDCCH#3和PDCCH#4，其中，PDCCH#3和PDCCH#4对应相同的DCI比特；PDCCH#3是指在PO#3中的PDCCH候选；PDCCH#4是指在PO#4中的PDCCH候选。In addition, the UE detects DCI format#2, which is used to schedule PDSCH#1, and the DCI format indicates the location of the HARQ-ACK information of PDSCH#1, that is, the PUCCH carrying the Type 1 HARQ-ACK codebook #1 location. In addition, the DCI format corresponds to PDCCH#3 and PDCCH#4, where PDCCH#3 and PDCCH#4 correspond to the same DCI bit; PDCCH#3 refers to the PDCCH candidate in PO#3; PDCCH#4 refers to the PDCCH candidate in PO#3; PDCCH candidates in #4.

在图5的示例中，由于该PUSCH#1与PUCCH#1在时域上重叠，因此UE不会发送PUCCH#1，而原本由PUCCH#1所承载的Type 1 HARQ-ACK codebook则由PUSCH#1承载。In the example in Figure 5, since the PUSCH#1 and PUCCH#1 overlap in the time domain, the UE will not send PUCCH#1, and the Type 1 HARQ-ACK codebook originally carried by PUCCH#1 is sent by PUSCH#1 1 bearer.

在上述例子中，将DCI format#1对应的两个PDCCH监测机会(PO#1，PO#2)中较晚的一个(PO#2)作为参考PDCCH监测机会(称为第二PDCCH监测机会)；将DCI format#2对应的两个PDCCH监测机会(PO#3，PO#4)中较早的一个(PO#3)作为参考PDCCH监测机会(称为第一PDCCH监测机会)。比较第二PDCCH监测机会(PO#2)和第一PDCCH监测机会(PO#3)，由于PO#3晚于PO#2，因此，UE没有能力为PDSCH#1生成HARQ-ACK信息比特值，因此，UE不为PDSCH#1返ACK而是将该PUSCH中包含的Type 1 HARQ-ACK codebook中PDSCH#1对应的比特设为NACK。In the above example, the later one (PO#2) of the two PDCCH monitoring opportunities (PO#1, PO#2) corresponding to DCI format#1 is used as the reference PDCCH monitoring opportunity (called the second PDCCH monitoring opportunity) ; The earlier one (PO#3) of the two PDCCH monitoring opportunities (PO#3, PO#4) corresponding to DCI format#2 is used as a reference PDCCH monitoring opportunity (referred to as the first PDCCH monitoring opportunity). Comparing the second PDCCH monitoring opportunity (PO#2) and the first PDCCH monitoring opportunity (PO#3), since PO#3 is later than PO#2, the UE has no ability to generate HARQ-ACK information bit value for PDSCH#1, Therefore, the UE does not return ACK for PDSCH#1 but sets the bit corresponding to PDSCH#1 in the Type 1 HARQ-ACK codebook contained in the PUSCH to NACK.

在上述例子中，将DCI format#1对应的两个PDCCH监测机会(PO#1，PO#2)中较晚的一个作为第二PDCCH监测机会，更具体地说是两个PDCCH监测机会中起始符号较晚的一个，或者说，两个PDCCH监测机会中结束符号较晚的一个作为第二PDCCH监测机会。In the above example, the later one of the two PDCCH monitoring opportunities (PO#1, PO#2) corresponding to DCI format#1 is used as the second PDCCH monitoring opportunity, more specifically, the starting point of the two PDCCH monitoring opportunities The later one of the start symbols, or in other words, the later one of the two PDCCH monitoring opportunities is used as the second PDCCH monitoring opportunity.

在上述例子中，将DCI format#2对应的两个PDCCH监测机会(PO#3，PO#4)中较早的一个作为第一PDCCH监测机会，更具体地说是两个PDCCH监测机会中起始符号较早的一个，或者说，两个PDCCH监测机会中结束符号较早的一个作为第一 PDCCH监测机会。In the above example, the earlier one of the two PDCCH monitoring opportunities (PO#3, PO#4) corresponding to DCI format#2 is used as the first PDCCH monitoring opportunity, more specifically, the first PDCCH monitoring opportunity among the two PDCCH monitoring opportunities The one whose start symbol is earlier, or in other words, the one whose end symbol is earlier among the two PDCCH monitoring opportunities is used as the first PDCCH monitoring opportunity.

图6是PDCCH监测机会的另一个示例的示意图，示出了第二PDCCH监测机会为第一DCI对应的两个PDCCH监测机会中较晚的一个，并且，第一PDCCH监测机会为第一信息对应的两个PDCCH监测机会中较晚的一个的情况。FIG. 6 is a schematic diagram of another example of a PDCCH monitoring opportunity, showing that the second PDCCH monitoring opportunity is the later one of the two PDCCH monitoring opportunities corresponding to the first DCI, and the first PDCCH monitoring opportunity is the one corresponding to the first information. The case of the later one of the two PDCCH monitoring opportunities.

在图6的示例中，与图5是示例不同的是，将DCI format#2对应的两个PDCCH监测机会(PO#3，PO#4)中较晚的一个(PO#4)作为参考PDCCH监测机会(称为第一PDCCH监测机会)。比较第二PDCCH监测机会(PO#2)和第一PDCCH监测机会(PO#4)，由于PO#4晚于PO#2，因此，UE没有能力为PDSCH#1生成HARQ-ACK信息比特值，因此，UE不为PDSCH#1返ACK而是将该PUSCH中包含的Type 1 HARQ-ACK codebook中PDSCH#1对应的比特设为NACK。In the example in Figure 6, the difference from the example in Figure 5 is that the later one (PO#4) of the two PDCCH monitoring opportunities (PO#3, PO#4) corresponding to DCI format#2 is used as the reference PDCCH A monitoring opportunity (referred to as the first PDCCH monitoring opportunity). Comparing the second PDCCH monitoring opportunity (PO#2) and the first PDCCH monitoring opportunity (PO#4), since PO#4 is later than PO#2, the UE has no ability to generate the HARQ-ACK information bit value for PDSCH#1, Therefore, the UE does not return ACK for PDSCH#1 but sets the bit corresponding to PDSCH#1 in the Type 1 HARQ-ACK codebook contained in the PUSCH to NACK.

在上述例子中，将DCI format#2对应的两个PDCCH监测机会(PO#3，PO#4)中较晚的一个作为第一PDCCH监测机会，更具体地说是两个PDCCH监测机会中起始符号较晚的一个，或者说，两个PDCCH监测机会中结束符号较晚的一个作为第一PDCCH监测机会。In the above example, the later one of the two PDCCH monitoring opportunities (PO#3, PO#4) corresponding to DCI format#2 is used as the first PDCCH monitoring opportunity, more specifically, the starting point of the two PDCCH monitoring opportunities The later one of the start symbols, or in other words, the later one of the two PDCCH monitoring opportunities is used as the first PDCCH monitoring opportunity.

图7是PDCCH监测机会的又一个示例的示意图，示出了第二PDCCH监测机会为第一DCI对应的两个PDCCH监测机会中较早的一个，并且，第一PDCCH监测机会为第一信息对应的两个PDCCH监测机会中较晚的一个的情况。7 is a schematic diagram of another example of a PDCCH monitoring opportunity, showing that the second PDCCH monitoring opportunity is the earlier one of the two PDCCH monitoring opportunities corresponding to the first DCI, and the first PDCCH monitoring opportunity is the first information corresponding to the first PDCCH monitoring opportunity. The case of the later one of the two PDCCH monitoring opportunities.

在图7的示例中，与图5的示例不同的是，将DCI format#1对应的两个PDCCH监测机会(PO#1，PO#2)中较早的一个(PO#1)作为参考PDCCH监测机会(称为第二PDCCH监测机会)；将DCI format#2对应的两个PDCCH监测机会(PO#3，PO#4)中较晚的一个(PO#4)作为参考PDCCH监测机会(称为第一PDCCH监测机会)。比较第二PDCCH监测机会(PO#1)和第一PDCCH监测机会(PO#4)，由于PO#4晚于PO#1，因此，UE没有能力为PDSCH#1生成HARQ-ACK信息比特值，因此，UE不为PDSCH#1返ACK而是将该PUSCH中包含的Type 1 HARQ-ACK codebook中PDSCH#1对应的比特设为NACK。In the example of FIG. 7, the difference from the example of FIG. 5 is that the earlier one (PO#1) of the two PDCCH monitoring opportunities (PO#1, PO#2) corresponding to DCI format#1 is used as the reference PDCCH A monitoring opportunity (called the second PDCCH monitoring opportunity); the later one (PO#4) of the two PDCCH monitoring opportunities (PO#3, PO#4) corresponding to DCI format#2 is used as a reference PDCCH monitoring opportunity (called is the first PDCCH monitoring opportunity). Comparing the second PDCCH monitoring opportunity (PO#1) and the first PDCCH monitoring opportunity (PO#4), since PO#4 is later than PO#1, the UE has no ability to generate the HARQ-ACK information bit value for PDSCH#1, Therefore, the UE does not return ACK for PDSCH#1 but sets the bit corresponding to PDSCH#1 in the Type 1 HARQ-ACK codebook contained in the PUSCH to NACK.

在上述例子中，将DCI format#1对应的两个PDCCH监测机会(PO#1，PO#2)中较早的一个作为第二PDCCH监测机会，更具体地说是两个PDCCH监测机会中起始符号较早的一个，或者说，两个PDCCH监测机会中结束符号较早的一个作为第二PDCCH监测机会。In the above example, the earlier one of the two PDCCH monitoring opportunities (PO#1, PO#2) corresponding to DCI format#1 is used as the second PDCCH monitoring opportunity, more specifically, the starting point of the two PDCCH monitoring opportunities The one with the earlier start symbol, or in other words, the one with the earlier end symbol among the two PDCCH monitoring opportunities is used as the second PDCCH monitoring opportunity.

图8是PDCCH监测机会的再一个示例的示意图，示出了第二PDCCH监测机会为第一DCI对应的两个PDCCH监测机会中较早的一个，并且，第一PDCCH监测机会为第一信息对应的两个PDCCH监测机会中较早的一个的情况。8 is a schematic diagram of another example of a PDCCH monitoring opportunity, showing that the second PDCCH monitoring opportunity is the earlier one of the two PDCCH monitoring opportunities corresponding to the first DCI, and the first PDCCH monitoring opportunity is the first information corresponding to the first PDCCH monitoring opportunity. The case of the earlier one of the two PDCCH monitoring opportunities.

在图8的示例中，与图5的示例不同的是，将DCI format#1对应的两个PDCCH监测机会(PO#1，PO#2)中较早的一个(PO#1)作为参考PDCCH监测机会(称为第二PDCCH监测机会)。比较第二PDCCH监测机会(PO#1)和第一PDCCH监测机会(PO#3)，由于PO#3晚于PO#1，因此，UE没有能力为PDSCH#1生成HARQ-ACK信息比特值，因此，UE不为PDSCH#1返ACK而是将该PUSCH中包含的Type 1 HARQ-ACK codebook中PDSCH#1对应的比特设为NACK。In the example of Figure 8, the difference from the example of Figure 5 is that the earlier one (PO#1) of the two PDCCH monitoring opportunities (PO#1, PO#2) corresponding to DCI format#1 is used as the reference PDCCH A monitoring opportunity (referred to as a second PDCCH monitoring opportunity). Comparing the second PDCCH monitoring opportunity (PO#1) and the first PDCCH monitoring opportunity (PO#3), since PO#3 is later than PO#1, the UE has no ability to generate HARQ-ACK information bit value for PDSCH#1, Therefore, the UE does not return ACK for PDSCH#1 but sets the bit corresponding to PDSCH#1 in the Type 1 HARQ-ACK codebook contained in the PUSCH to NACK.

在一些实施例中，如前所述，第一DCI对应一个PDCCH监测机会，第一信息对应两个PDCCH监测机会。In some embodiments, as mentioned above, the first DCI corresponds to one PDCCH monitoring opportunity, and the first information corresponds to two PDCCH monitoring opportunities.

图9是PDCCH监测机会的一个示例的示意图，示出了第二PDCCH监测机会为第一DCI对应的PDCCH监测机会，第一PDCCH监测机会为第一信息对应的两个PDCCH监测机会中较早的一个的情况。Figure 9 is a schematic diagram of an example of a PDCCH monitoring opportunity, showing that the second PDCCH monitoring opportunity is the PDCCH monitoring opportunity corresponding to the first DCI, and the first PDCCH monitoring opportunity is the earlier of the two PDCCH monitoring opportunities corresponding to the first information A case.

如图9所示，UE检测到基站的指示信息，该指示信息指示UE反馈type 1 HARQ-ACK codebook。本申请对上述指示信息不做限制。As shown in Figure 9, the UE detects the indication information from the base station, and the indication information indicates that the UE feeds back a type 1 HARQ-ACK codebook. This application does not limit the above instruction information.

此外，UE检测到DCI format#1，该DCI格式用于调度PUSCH#1，并且，该DCI格式对应PDCCH#1；PDCCH#1是指在PO#1中的PDCCH候选。In addition, the UE detects DCI format#1, the DCI format is used to schedule PUSCH#1, and the DCI format corresponds to PDCCH#1; PDCCH#1 refers to the PDCCH candidate in PO#1.

此外，UE检测到DCI format#2，该DCI格式用于调度PDSCH#1，并且，该DCI格式指示PDSCH#1的HARQ-ACK信息所在的位置，也即，承载Type 1 HARQ-ACK codebook的PUCCH#1的位置。此外，该DCI格式对应PDCCH#2和PDCCH#3，其中，PDCCH#2和PDCCH#3对应相同的DCI比特；PDCCH#2是指在PO#2中的PDCCH候选；PDCCH#3是指在PO#3中的PDCCH候选。In addition, the UE detects DCI format#2, which is used to schedule PDSCH#1, and the DCI format indicates the location of the HARQ-ACK information of PDSCH#1, that is, the PUCCH carrying the Type 1 HARQ-ACK codebook #1 location. In addition, the DCI format corresponds to PDCCH#2 and PDCCH#3, where PDCCH#2 and PDCCH#3 correspond to the same DCI bit; PDCCH#2 refers to the PDCCH candidate in PO#2; PDCCH#3 refers to the PDCCH candidate in PO#2; PDCCH candidates in #3.

在图9的示例中，由于该PUSCH#1与PUCCH#1在时域上重叠，因此UE不会发送PUCCH#1，而原本由PUCCH#1所承载的Type 1 HARQ-ACK codebook则由PUSCH#1承载。In the example in Figure 9, since the PUSCH#1 and PUCCH#1 overlap in the time domain, the UE will not send PUCCH#1, and the Type 1 HARQ-ACK codebook originally carried by PUCCH#1 is sent by PUSCH#1 1 bearer.

在上述例子中，将DCI format#1对应的PDCCH监测机会(PO#1)作为参考PDCCH监测机会(称为第二PDCCH监测机会)；将DCI format#2对应的两个PDCCH监测机会(PO#2，PO#3)中较早的一个(PO#2)作为参考PDCCH监测机会(称为第一PDCCH监测机会)。比较第二PDCCH监测机会(PO#1)和第一PDCCH监测机会(PO#2)，由于PO#2晚于PO#1，因此，UE没有能力为PDSCH#1生成HARQ-ACK信息比特，因此，UE不为PDSCH#1返ACK而是将该PUSCH中包含的Type 1 HARQ-ACK codebook中PDSCH#1对应的比特设为NACK。In the above example, the PDCCH monitoring opportunity (PO#1) corresponding to DCI format#1 is used as a reference PDCCH monitoring opportunity (called the second PDCCH monitoring opportunity); two PDCCH monitoring opportunities (PO#1) corresponding to DCI format#2 are used as 2, the earlier one (PO#2) of PO#3) is used as a reference PDCCH monitoring opportunity (referred to as the first PDCCH monitoring opportunity). Comparing the second PDCCH monitoring opportunity (PO#1) and the first PDCCH monitoring opportunity (PO#2), since PO#2 is later than PO#1, the UE has no ability to generate HARQ-ACK information bits for PDSCH#1, so , the UE does not return ACK for PDSCH#1 but sets the bit corresponding to PDSCH#1 in the Type 1 HARQ-ACK codebook contained in the PUSCH to NACK.

在上述例子中，将DCI format#2对应的两个PDCCH监测机会(PO#2，PO#3)中较早的一个作为第一PDCCH监测机会，更具体地说是两个PDCCH监测机会中起始符号较早的一个，或者说，两个PDCCH监测机会中结束符号较早的一个作为第一PDCCH监测机会。In the above example, the earlier one of the two PDCCH monitoring opportunities (PO#2, PO#3) corresponding to DCI format#2 is used as the first PDCCH monitoring opportunity, more specifically, the first PDCCH monitoring opportunity among the two PDCCH monitoring opportunities The one whose start symbol is earlier, or in other words, the one whose end symbol is earlier among the two PDCCH monitoring opportunities is used as the first PDCCH monitoring opportunity.

图10是PDCCH监测机会的另一个示例的示意图，示出了第二PDCCH监测机会为第一DCI对应的PDCCH监测机会，并且，第一PDCCH监测机会为第一信息对应的两个PDCCH监测机会中较晚的一个的情况。10 is a schematic diagram of another example of a PDCCH monitoring opportunity, showing that the second PDCCH monitoring opportunity is the PDCCH monitoring opportunity corresponding to the first DCI, and the first PDCCH monitoring opportunity is one of the two PDCCH monitoring opportunities corresponding to the first information The case of the later one.

在图10的示例中，与图9的示例不同的是，将DCI format#2对应的两个PDCCH监测机会(PO#2，PO#3)中较晚的一个(PO#3)作为参考PDCCH监测机会(称为第一PDCCH监测机会)。比较第二PDCCH监测机会(PO#1)和第一PDCCH监测机会(PO#3)，由于PO#3晚于PO#1，因此，UE没有能力为PDSCH#1生成HARQ-ACK信息比特值，因此，UE不为PDSCH#1返ACK而是将该PUSCH中包含的Type 1 HARQ-ACK codebook中PDSCH#1对应的比特设为NACK。In the example of FIG. 10, different from the example of FIG. 9, the later one (PO#3) of the two PDCCH monitoring opportunities (PO#2, PO#3) corresponding to DCI format#2 is used as the reference PDCCH A monitoring opportunity (referred to as the first PDCCH monitoring opportunity). Comparing the second PDCCH monitoring opportunity (PO#1) and the first PDCCH monitoring opportunity (PO#3), since PO#3 is later than PO#1, the UE has no ability to generate HARQ-ACK information bit value for PDSCH#1, Therefore, the UE does not return ACK for PDSCH#1 but sets the bit corresponding to PDSCH#1 in the Type 1 HARQ-ACK codebook contained in the PUSCH to NACK.

在上述例子中，将DCI format#2对应的两个PDCCH监测机会(PO#2，PO#3)中较晚的一个作为第一PDCCH监测机会，更具体地说是两个PDCCH监测机会中起始符号较晚的一个，或者说，两个PDCCH监测机会中结束符号较晚的一个作为第一PDCCH监测机会。In the above example, the later one of the two PDCCH monitoring opportunities (PO#2, PO#3) corresponding to DCI format#2 is used as the first PDCCH monitoring opportunity, more specifically, the starting point of the two PDCCH monitoring opportunities The later one of the start symbols, or in other words, the later one of the two PDCCH monitoring opportunities is used as the first PDCCH monitoring opportunity.

在一些实施例中，如前所述，第一DCI对应两个PDCCH监测机会，第一信息对应一个PDCCH监测机会。In some embodiments, as mentioned above, the first DCI corresponds to two PDCCH monitoring opportunities, and the first information corresponds to one PDCCH monitoring opportunity.

图11是PDCCH监测机会的一个示例的示意图，示出了第二PDCCH监测机会为第一DCI对应的两个PDCCH监测机会中较晚的一个，并且，第一PDCCH监测机会为第一信息对应的PDCCH监测机会的情况。11 is a schematic diagram of an example of a PDCCH monitoring opportunity, showing that the second PDCCH monitoring opportunity is the later one of the two PDCCH monitoring opportunities corresponding to the first DCI, and the first PDCCH monitoring opportunity is the one corresponding to the first information. The status of PDCCH monitoring opportunities.

如图11所示，UE检测到基站的指示信息，该指示信息指示UE反馈type 1 HARQ-ACK codebook。本申请对上述指示信息不做限制。As shown in Figure 11, the UE detects the indication information from the base station, and the indication information instructs the UE to feed back a type 1 HARQ-ACK codebook. This application does not limit the above instruction information.

此外，UE检测到DCI format#2，该DCI格式用于调度PDSCH#1，并且，该DCI格式指示PDSCH#1的HARQ-ACK信息所在的位置，也即，承载Type 1 HARQ-ACK codebook的PUCCH#1的位置。此外，该DCI格式对应PDCCH#3，PDCCH#3是指在PO#3中的PDCCH候选。In addition, the UE detects DCI format#2, which is used to schedule PDSCH#1, and the DCI format indicates the location of the HARQ-ACK information of PDSCH#1, that is, the PUCCH carrying the Type 1 HARQ-ACK codebook #1 location. In addition, the DCI format corresponds to PDCCH #3, and PDCCH #3 refers to a PDCCH candidate in PO #3.

在图11的示例中，由于该PUSCH#1与PUCCH#1在时域上重叠，因此UE不会发送PUCCH#1，而原本由PUCCH#1所承载的Type 1 HARQ-ACK codebook则由PUSCH#1承载。In the example in Figure 11, since the PUSCH#1 and PUCCH#1 overlap in the time domain, the UE will not send PUCCH#1, and the Type 1 HARQ-ACK codebook originally carried by PUCCH#1 is sent by PUSCH#1 1 bearer.

在上述例子中，将DCI format#1对应的两个PDCCH监测机会(PO#1，PO#2)中较晚的一个(PO#2)作为参考PDCCH监测机会(称为第二PDCCH监测机会)；将DCI format#2对应的PDCCH监测机会(PO#3)作为参考PDCCH监测机会(称为第一PDCCH监测机会)。比较第二PDCCH监测机会(PO#2)和第一PDCCH监测机会(PO#3)，由于PO#3晚于PO#2，因此，UE没有能力为PDSCH#1生成HARQ-ACK信息比特值，因此，UE不为PDSCH#1返ACK而是将该PUSCH中包含的Type 1 HARQ-ACK codebook中PDSCH#1对应的比特设为NACK。In the above example, the later one (PO#2) of the two PDCCH monitoring opportunities (PO#1, PO#2) corresponding to DCI format#1 is used as the reference PDCCH monitoring opportunity (called the second PDCCH monitoring opportunity) ; Use the PDCCH monitoring opportunity (PO#3) corresponding to DCI format#2 as a reference PDCCH monitoring opportunity (referred to as the first PDCCH monitoring opportunity). Comparing the second PDCCH monitoring opportunity (PO#2) and the first PDCCH monitoring opportunity (PO#3), since PO#3 is later than PO#2, the UE has no ability to generate HARQ-ACK information bit value for PDSCH#1, Therefore, the UE does not return ACK for PDSCH#1 but sets the bit corresponding to PDSCH#1 in the Type 1 HARQ-ACK codebook contained in the PUSCH to NACK.

图12是PDCCH监测机会的一个示例的示意图，示出了第二PDCCH监测机会为第一DCI对应的两个PDCCH监测机会中较早的一个，并且，第一PDCCH监测机会为第一信息对应的PDCCH监测机会的情况。Fig. 12 is a schematic diagram of an example of a PDCCH monitoring opportunity, showing that the second PDCCH monitoring opportunity is the earlier one of the two PDCCH monitoring opportunities corresponding to the first DCI, and the first PDCCH monitoring opportunity is the one corresponding to the first information The status of PDCCH monitoring opportunities.

在图12的示例中，与图11的示例不同的是，将DCI format#1对应的两个PDCCH监测机会(PO#1，PO#2)中较早的一个(PO#1)作为参考PDCCH监测机会(称为第二PDCCH监测机会)。比较第二PDCCH监测机会(PO#1)和第一PDCCH监测机会(PO#3)，由于PO#3晚于PO#1，因此，UE没有能力为PDSCH#1生成HARQ-ACK信息比特值，因此，UE不为PDSCH#1返ACK而是将该PUSCH中包含的Type 1 HARQ-ACK codebook中PDSCH#1对应的比特设为NACK。In the example in Figure 12, the difference from the example in Figure 11 is that the earlier one (PO#1) of the two PDCCH monitoring opportunities (PO#1, PO#2) corresponding to DCI format#1 is used as the reference PDCCH A monitoring opportunity (referred to as a second PDCCH monitoring opportunity). Comparing the second PDCCH monitoring opportunity (PO#1) and the first PDCCH monitoring opportunity (PO#3), since PO#3 is later than PO#1, the UE has no ability to generate HARQ-ACK information bit value for PDSCH#1, Therefore, the UE does not return ACK for PDSCH#1 but sets the bit corresponding to PDSCH#1 in the Type 1 HARQ-ACK codebook contained in the PUSCH to NACK.
