本公开涉及通信应用的技术领域,尤其涉及一种混合自动重传请求的传输方法、终端及基站。The present disclosure relates to the technical field of communication applications, and in particular, to a transmission method, a terminal, and a base station of a hybrid automatic repeat request.
目前5G中在确定动态混合自动重传请求确认(HARQ-ACK)反馈码本时,需要首先确定在同一个物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)进行反馈的物理下行控制信道(Physical Downlink Control Channel,PDCCH)检测机会集合。其中,3GPP协议中规定PUCCH资源使用的PUCCH格式包括:PUCCH格式0、PUCCH格式1、PUCCH格式2、PUCCH格式3和PUCCH格式4。当前存在的问题是,由于不同PDCCH检测机会中传输的下行控制信息(Downlink Control Information,DCI)包含的PUCCH资源指示(PUCCH resource indicator,PRI,也称为ARI)可以指示不同的PUCCH资源,终端无法确定在同一个时隙slot反馈HARQ-ACK的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或半持续性调度(Semi-Persistent Scheduling,SPS)释放对应的DCI是否属于在同一个PUCCH进行反馈的PDCCH检测机会集合,导致可能出现基站和终端对于HARQ-ACK反馈资源理解不一致的情况,影响***传输性能。In the current 5G, when determining a dynamic hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback codebook, it is necessary to first determine a physical downlink control channel that is fed back on the same physical uplink control channel (PUCCH). The Physical Downlink Control Channel (PDCCH) detects a set of opportunities. The PUCCH format that specifies the PUCCH resource usage in the 3GPP protocol includes: PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, and PUCCH format 4. The current problem is that the PUCCH resource indicator (PRI, also referred to as ARI) included in the Downlink Control Information (DCI) transmitted by the PDCCH detection opportunity may indicate different PUCCH resources, and the terminal cannot Determining whether the corresponding downlink DCI of the Physical Downlink Shared Channel (PDSCH) or the Semi-Persistent Scheduling (SPS) of the HARQ-ACK in the same slot is fed back in the same PUCCH for feedback. The PDCCH detection opportunity set may cause inconsistencies in the understanding of the HARQ-ACK feedback resources by the base station and the terminal, and affect the system transmission performance.
例如,如图1和图2所示,假设高层信令配置PDSCH至HARQ-ACK检测的slot个数为1~8,在时隙n至时隙n+7中PDSCH的DCI均指示对应的HARQ-ACK反馈信息在时隙n+8进行传输。DCI中的计数下行分配索引(Counter-Downlink Assignment Indicator,C-DAI)和PRI指示如图中所示。终端无法确定在所述情况下时隙n至时隙n+7中PDSCH的DCI是否属于在 同一个PUCCH进行反馈的PDCCH检测机会集合,如在图1中,终端理解为时隙n至时隙n+3中PDSCH对应的反馈信息在时隙n+8中PRI=00对应的PUCCH资源上传输,时隙n+4至时隙n+7中PDSCH对应的反馈信息在时隙n+8中PRI=01对应的PUCCH资源上传输。在图2中,终端理解为时隙n至时隙n+7中PDSCH对应的反馈信息都在时隙n+8中PRI=01对应的PUCCH资源上传输。For example, as shown in FIG. 1 and FIG. 2, it is assumed that the number of slots in the high-level signaling configuration PDSCH-to-HARQ-ACK detection is 1-8, and the DCI of the PDSCH in the slot n to the slot n+7 indicates the corresponding HARQ. The -ACK feedback information is transmitted in time slot n+8. The Counter-Downlink Assignment Indicator (C-DAI) and PRI indications in the DCI are as shown in the figure. The terminal cannot determine whether the DCI of the PDSCH in the slot n to the slot n+7 belongs to the PDCCH detection opportunity set fed back in the same PUCCH in the case described, as in FIG. 1, the terminal understands that the slot n to the slot The feedback information corresponding to the PDSCH in n+3 is transmitted on the PUCCH resource corresponding to PRI=00 in the slot n+8, and the feedback information corresponding to the PDSCH in the slot n+4 to the slot n+7 is in the slot n+8. The PUCCH resource corresponding to PRI=01 is transmitted. In FIG. 2, the terminal understands that the feedback information corresponding to the PDSCH in the slot n to the slot n+7 is transmitted on the PUCCH resource corresponding to PRI=01 in the slot n+8.
对于超高可靠超低时延通信(URLLC)业务,由于时延要求较高,如果限制在一个slot内仅能传输一个PUCCH,则会增加反馈时延,因此需要支持UE在一个slot内传输至少两个PUCCH。但是在使用动态码本时,目前还没有办法确定在同一个slot进行反馈的PDSCH或SPS释放对应的HARQ-ACK是否在所述slot内的同一个PUCCH上传输。For the ultra-high-reliability ultra-low latency communication (URLLC) service, because the delay requirement is high, if only one PUCCH can be transmitted in one slot, the feedback delay is increased, so the UE needs to support at least one slot in the slot. Two PUCCHs. However, when using the dynamic codebook, there is currently no way to determine whether the HARQ-ACK corresponding to the PDSCH or SPS release that is fed back in the same slot is transmitted on the same PUCCH in the slot.

目前在NR通信***中,支持HARQ-ACK反馈使用动态码本方案。Currently in the NR communication system, the HARQ-ACK feedback is supported using a dynamic codebook scheme.
在配置用户使用动态码本方案时,DCI格式1_0中包含2比特的计数DAI;DCI格式1_1中包含2比特的计数DAI和2比特的总DAI,该DCI格式1_0和DCI格式1_1为3GPP协议中规定的DCI格式。When configuring the user to use the dynamic codebook scheme, the DCI format 1_0 includes a 2-bit count DAI; the DCI format 1_1 includes a 2-bit count DAI and a 2-bit total DAI, and the DCI format 1_0 and the DCI format 1_1 are in the 3GPP protocol. The specified DCI format.
下行DCI中的计数DAI指在反馈窗口内,按照先载波索引增加然后PDCCH检测机会索引增加的顺序,到目前载波和目前PDCCH检测机会为止,所有DCI格式1_0或者DCI格式1_1调度的PDSCH传输和DCI格式1_0指示下行SPS释放的累积个数。下行DCI中的总DAI指在反馈窗口内,到目前PDCCH检测机会为止,所有DCI格式1_0或者DCI格式1_1调度的PDSCH传输和DCI格式1_0指示下行SPS释放的个数,会逐个PDCCH检测机会进行更新。其中反馈窗口为M个PDCCH检测机会的集合,基于高层信令配置的最大和最小数据到反馈之间的间隔,UE可以确定出用于DCI格式1_0或者DCI格式1_1传输的PDCCH检测机会集合,对应DCI调度的PDSCH或SPS释放在同一个PUCCH反馈HARQ-ACK。The count DAI in the downlink DCI refers to the PDSCH transmission and DCI scheduled by all DCI formats 1_0 or DCI format 1_1 in the feedback window according to the order in which the first carrier index is increased and then the PDCCH detection opportunity index is increased, up to the current carrier and the current PDCCH detection opportunity. The format 1_0 indicates the cumulative number of downlink SPS releases. The total DAI in the downlink DCI refers to the number of PDSCH transmissions scheduled by the DCI format 1_0 or DCI format 1_1 and the number of downlink SPS releases indicated by the DCI format 1_1 in the feedback window, which will be updated one by one. . The feedback window is a set of M PDCCH detection opportunities. Based on the interval between the maximum and minimum data to feedback configured by the high layer signaling, the UE may determine a PDCCH detection opportunity set for DCI format 1_0 or DCI format 1_1 transmission, corresponding to The DCI scheduled PDSCH or SPS release feedback HARQ-ACK on the same PUCCH.
在确定PDSCH或者下行SPS释放的DCI和对应的HARQ-ACK之间的反馈时序时,HARQ-ACK反馈信息所在的时隙和在反馈时隙中使用的PUCCH资源通过高层信令和/或DCI中不同的信息域指示确定。具体的,高 层信令配置给终端一个或者最多8个HARQ时序值,并通过DCI中包含的3比特HARQ时序指示信息确定HARQ-ACK反馈信息的传输时隙。In determining the feedback timing between the PDSCH or the downlink SPS released DCI and the corresponding HARQ-ACK, the time slot in which the HARQ-ACK feedback information is located and the PUCCH resource used in the feedback slot pass through higher layer signaling and/or DCI Different information fields indicate ok. Specifically, the high layer signaling configures one or a maximum of eight HARQ timing values to the terminal, and determines a transmission time slot of the HARQ-ACK feedback information by using the 3-bit HARQ timing indication information included in the DCI.
对于PUCCH资源指示,在RRC连接建立之前,基站通过高层信令配置给终端16个PUCCH资源。在RRC连接建立之后,基站通过RRC信令配置给终端最多4个PUCCH资源集合。如果终端传输的UCI比特数小于等于2,则使用第一个PUCCH资源集合;如果终端传输的UCI比特数大于2小于等于N2,则使用第二个PUCCH资源集合;如果终端传输的UCI比特数大于N2小于等于N3,则使用第三个PUCCH资源集合;如果终端传输的UCI比特数大于N3小于等于1706,则使用第四个PUCCH资源集合;其中N2和N3为RRC信令配置的值。第一个PUCCH资源集合中最多包含32个PUCCH资源,其它的PUCCH资源集合中最多包含8个PUCCH资源。如果PUCCH资源集合中的PUCCH资源个数小于等于8,基站通过DCI中包含的3比特PUCCH资源指示信息确定HARQ-ACK反馈使用的PUCCH资源;如果PUCCH资源集合中的PUCCH资源个数大于8,基站通过DCI中包含的3比特PUCCH资源指示信息和DCI所在PDCCH的最小控制信道单元CCE编号隐式确定HARQ-ACK反馈使用的PUCCH资源。For the PUCCH resource indication, the base station allocates 16 PUCCH resources to the terminal through high layer signaling before the RRC connection is established. After the RRC connection is established, the base station configures the terminal with a maximum of 4 PUCCH resource sets through RRC signaling. If the number of UCI bits transmitted by the terminal is less than or equal to 2, the first PUCCH resource set is used; if the number of UCI bits transmitted by the terminal is greater than 2 and less than or equal to N2, the second PUCCH resource set is used; if the UCI bit number transmitted by the terminal is greater than If N2 is less than or equal to N3, a third PUCCH resource set is used; if the number of UCI bits transmitted by the terminal is greater than N3 and less than or equal to 1706, a fourth PUCCH resource set is used; wherein N2 and N3 are values configured by RRC signaling. A maximum of 32 PUCCH resources are included in the first PUCCH resource set, and a maximum of 8 PUCCH resources are included in other PUCCH resource sets. If the number of PUCCH resources in the PUCCH resource set is less than or equal to 8, the base station determines, by using the 3-bit PUCCH resource indication information included in the DCI, the PUCCH resource used by the HARQ-ACK feedback; if the number of PUCCH resources in the PUCCH resource set is greater than 8, the base station The PUCCH resource used for HARQ-ACK feedback is implicitly determined by the 3-bit PUCCH resource indication information included in the DCI and the minimum control channel element CCE number of the PDCCH where the DCI is located.

需要说明的是,本公开实施例的上述传输方法是针对仅对URLLC业务使用的传输方法,对于同时支持eMBB和URLLC业务的UE,eMBB业务的PDSCH对应的HARQ-ACK在一个slot内仅能通过一个PUCCH资源传输,URLLC业务的PDSCH对应的HARQ-ACK在一个slot内可以通过一个或多个PUCCH资源传输。It should be noted that the foregoing transmission method in the embodiment of the present disclosure is directed to a transmission method used only for the URLLC service. For a UE that supports both eMBB and URLLC services, the HARQ-ACK corresponding to the PDSCH of the eMBB service can only pass through one slot. For one PUCCH resource transmission, the HARQ-ACK corresponding to the PDSCH of the URLLC service may be transmitted through one or more PUCCH resources in one slot.
另外,当UE同时支持eMBB和URLLC业务传输时,这两种业务对应的ACK/NACK不在同一个PUCCH资源上复用传输。In addition, when the UE supports both the eMBB and the URLLC service transmission, the ACK/NACK corresponding to the two services is not multiplexed and transmitted on the same PUCCH resource.

The DCI corresponding to the HARQ feedback information transmitted on the different PUCCHs in the same time slot is different from the PRI, and can support the terminal to use the multiple PUCCHs to transmit the HARQ feedback information in one slot, so that the terminal can determine the HARQ feedback information in the same time slot.

The DCI corresponding to the HARQ feedback information transmitted on the different PUCCHs in the same time slot is different from the PRI, and can support the terminal to use the multiple PUCCHs to transmit the HARQ feedback information in one slot, so that the terminal can determine the HARQ feedback information in the same time slot. Whether the transmission is performed on the same PUCCH in the time slot, so as to avoid the inconsistency of the understanding of the feedback resources between the current base station and the terminal, in particular, the HARQ feedback delay is reduced for the URLLC service, thereby improving the transmission performance of the system.

At this time, the base station may configure more than one PUCCH resource set for the eMBB service, and if the base station configures the same first PUCCH resource set for the eMBB service and the URLLC service, when the eMBB service uses the PUCCH resource transmission in the first PUCCH resource set.

The DCI corresponding to the HARQ feedback information transmitted on the different PUCCHs in the same time slot is different from the PRI, and can support the terminal to use the multiple PUCCHs to transmit the HARQ feedback information in one slot, so that the terminal can determine the HARQ feedback information in the same time slot.

下面结合具体实施例对本公开实施例的混合自动重传请求的传输方法进行说明。A method for transmitting a hybrid automatic repeat request according to an embodiment of the present disclosure will be described below with reference to specific embodiments.
实施例1:Example 1:
假设一个终端仅支持URLLC业务传输,且在一个时隙中最多有两个时分复用的PUCCH资源可用于传输ACK/NACK信息。当基站仅为UE配置了一个PUCCH资源集合且该集合中包含8个PUCCH资源时,假设高层信令配 置PDSCH至HARQ-ACK检测的slot个数为1和2,在时隙n至时隙n+1中PDSCH的DCI均指示对应的HARQ-ACK反馈信息在时隙n+2进行传输。UE具体的反馈分为以下不同的情况:It is assumed that one terminal only supports URLLC traffic transmission, and up to two time division multiplexed PUCCH resources in one slot can be used to transmit ACK/NACK information. When the base station configures only one PUCCH resource set for the UE and the 8 PUCCH resources are included in the set, it is assumed that the number of slots for the PDSCH-to-HARQ-ACK detection is 1 and 2, and the time slot n to the time slot n. The DCI of the PDSCH in +1 indicates that the corresponding HARQ-ACK feedback information is transmitted in the slot n+ 2. UE specific feedback is divided into the following different situations:
情况A:如图5所示,在时隙n和时隙n+1中,PDSCH对应的DCI中的C-DAI指示分别为1和2,而DCI中的PRI指示均为000,因此,时隙n和时隙n+1中PDSCH的反馈信息均使用高层信令配置的PUCCH资源集合中的第一个PUCCH资源传输;Case A: As shown in FIG. 5, in slot n and slot n+1, the C-DAI indications in the DCI corresponding to the PDSCH are 1 and 2, respectively, and the PRI indications in the DCI are both 000, therefore, The feedback information of the PDSCH in the slot n and the slot n+1 is transmitted by using the first PUCCH resource in the PUCCH resource set configured by the high layer signaling;
情况B:如图6所示,在时隙n至时隙n+1中,PDSCH对应的DCI中的C-DAI指示均为1,而在时隙n中,PDSCH对应的DCI中的PRI指示为000,在时隙n+1中,PDSCH对应的DCI中的PRI指示为001,因此,时隙n中PDSCH的反馈信息使用高层信令配置的PUCCH资源集合中的第一个PUCCH资源传输,时隙n+1中PDSCH的反馈信息使用高层信令配置的PUCCH资源集合中的第二个PUCCH资源传输。Case B: As shown in FIG. 6, in the slot n to the slot n+1, the C-DAI indication in the DCI corresponding to the PDSCH is 1, and in the slot n, the PRI indication in the DCI corresponding to the PDSCH In the slot n+1, the PRI indication in the DCI corresponding to the PDSCH is 001. Therefore, the feedback information of the PDSCH in the slot n is transmitted using the first PUCCH resource in the PUCCH resource set configured by the high layer signaling. The feedback information of the PDSCH in the slot n+1 is transmitted using the second PUCCH resource in the PUCCH resource set configured by the high layer signaling.
情况C:如图7所示,在时隙n中,基站调度了两个PDSCH,对应的DCI中的C-DAI指示分别为1和2,而PRI指示均为000,在时隙n+1中,基站调度了两个PDSCH,对应的DCI中的C-DAI指示分别为1和2,而PRI指示均为001,因此,时隙n中两个PDSCH的反馈信息使用高层信令配置的PUCCH资源集合中的第一个PUCCH资源传输,时隙n+1中两个PDSCH的反馈信息使用高层信令配置的PUCCH资源集合中的第二个PUCCH资源传输;Case C: As shown in FIG. 7, in slot n, the base station schedules two PDSCHs, and the C-DAI indications in the corresponding DCI are 1 and 2, respectively, and the PRI indications are all 000, in the slot n+ 1. The base station schedules two PDSCHs, and the C-DAI indications in the corresponding DCI are 1 and 2, respectively, and the PRI indications are all 001. Therefore, the feedback information of the two PDSCHs in the slot n uses the PUCCH configured by the high layer signaling. The first PUCCH resource in the resource set is transmitted, and the feedback information of the two PDSCHs in the slot n+1 is transmitted by using the second PUCCH resource in the PUCCH resource set configured by the high layer signaling;
情况D:如图8所示,在时隙n中,基站调度了两个载波上的两个PDSCH,对应的DCI中的C-DAI指示分别为1和2,而PRI指示均为000,在时隙n+1中,基站调度了两个载波上的两个PDSCH,对应的DCI中的C-DAI指示分别为1和2,而ARI指示均为001,因此,时隙n中两个PDSCH的反馈信息使用高层信令配置的PUCCH资源集合中的第一个PUCCH资源传输,时隙n+1中两个PDSCH的反馈信息使用高层信令配置的PUCCH资源集合中的第二个PUCCH资源传输。Case D: As shown in FIG. 8, in the slot n, the base station schedules two PDSCHs on two carriers, and the C-DAI indications in the corresponding DCI are 1 and 2, respectively, and the PRI indications are all 000. In slot n+1, the base station schedules two PDSCHs on two carriers, the C-DAI indications in the corresponding DCI are 1 and 2, respectively, and the ARI indications are all 001. Therefore, two PDSCHs in slot n The feedback information is transmitted by using the first PUCCH resource in the PUCCH resource set configured by the high layer signaling, and the feedback information of the two PDSCHs in the slot n+1 is transmitted by using the second PUCCH resource in the PUCCH resource set configured by the high layer signaling. .
实施例2:Example 2:
假设一个终端同时支持eMBB业务和URLLC业务传输,并且能够通过某种方式确定PDSCH是针对哪一种业务的传输。所述终端在一个时隙中最 多有两个时分复用的PUCCH资源可用于传输ACK/NACK信息。基站在配置PUCCH资源时,有如下两种方式:It is assumed that a terminal supports both eMBB service and URLLC service transmission, and can determine in some way which transmission of the PDSCH is for which service. The terminal has up to two time division multiplexed PUCCH resources in one slot for transmitting ACK/NACK information. When configuring a PUCCH resource, the base station has the following two methods:
方式一:在配置资源时不区分eMBB和URLLC,基站为UE配置两个PUCCH资源集合且每个集合中分别包含8个PUCCH资源,其中第一个PUCCH资源集合用于传输1~2比特的ACK/NACK信息,第二个PUCCH资源集合用于传输大于2比特的ACK/NACK信息。Manner 1: The eMBB and the URLLC are not distinguished when the resource is configured. The base station configures two PUCCH resource sets for the UE and each of the sets includes 8 PUCCH resources, where the first PUCCH resource set is used to transmit the ACK of 1 to 2 bits. /NACK information, the second PUCCH resource set is used to transmit ACK/NACK information greater than 2 bits.
方式二:在配置资源时区分eMBB和URLLC,基站为UE的eMBB业务配置两个PUCCH资源集合且每个集合中分别包含8个PUCCH资源,其中第一个PUCCH资源集合用于传输1~2比特的ACK/NACK信息,第二个PUCCH资源集合用于传输大于2比特的ACK/NACK信息;为URLLC业务另外配置一组PUCCH资源集合,用于传输1~2比特的ACK/NACK信息;Manner 2: The eMBB and the URLLC are distinguished when the resource is configured. The base station configures two PUCCH resource sets for the eMBB service of the UE, and each of the sets includes 8 PUCCH resources, where the first PUCCH resource set is used for transmitting 1-2 bits. ACK/NACK information, the second PUCCH resource set is used to transmit ACK/NACK information greater than 2 bits; and a set of PUCCH resource sets are additionally configured for the URLLC service, for transmitting 1-2/bit ACK/NACK information;
类似地,基站在配置PDSCH至HARQ-ACK反馈间隔的slot个数时,也有如下两种方式:Similarly, when configuring the number of slots in the PDSCH to HARQ-ACK feedback interval, the base station also has the following two methods:
方式一:在配置时不区分eMBB和URLLC,基站为UE配置PDSCH至HARQ-ACK反馈间隔的slot个数为1~8;Manner 1: The eMBB and the URLLC are not distinguished in the configuration, and the number of slots in which the base station configures the PDSCH to the HARQ-ACK feedback interval for the UE is 1 to 8;
方式二:在配置资源时区分eMBB和URLLC,基站为UE的eMBB业务配置PDSCH至HARQ-ACK反馈间隔的slot个数为1~8;为URLLC业务PDSCH至HARQ-ACK反馈间隔的slot个数为1~2;Manner 2: The eMBB and the URLLC are distinguished when the resource is configured. The number of slots for the PDSCH to HARQ-ACK feedback interval is 1 to 8 for the eMBB service of the UE. The number of slots for the feedback interval of the URLSCH service from the PDSCH to the HARQ-ACK is 1 to 2;
基站指示在时隙n至时隙n+7中PDSCH对应的HARQ-ACK反馈信息在时隙n+8进行传输。UE具体的反馈分为以下不同的情况:The base station indicates that the HARQ-ACK feedback information corresponding to the PDSCH in slot n to slot n+7 is transmitted in slot n+8. UE specific feedback is divided into the following different situations:
情况A:如图9所示,在时隙n、时隙n+2和时隙n+6中,基站调度了传输eMBB业务的PDSCH,对应的DCI中PRI分别为000、011和111,在时隙n+6和时隙n+7中,基站调度了传输URLLC业务的PDSCH,对应的DCI中PRI均为000。对于eMBB业务,在slot n+8对应的反馈窗内由于UE最后一个检测到的DCI为slot n+6中传输的PDSCH对应的DCI,因此使用slot n+6中传输的PDSCH对应的DCI指示的PUCCH资源进行反馈,由于反馈比特数大于2,则终端使用PUCCH资源集合2(是eMBB专用的资源集合)中的第八个PUCCH资源进行反馈;对于URLLC业务,在时隙n+6和时隙n+7中,UE接收到两个PDSCH对应的DCI中的C-DAI指示分别为1和2, 而DCI中的PRI指示均为000,因此,时隙n+6和时隙n+7中URLLC业务的PDSCH的反馈信息均使用高层信令配置的第一个PUCCH资源集合(即资源集合1,可以是URLLC专用的资源集合,或者是eMBB和URLLC通用的资源集合)中的第一个PUCCH资源传输。Case A: As shown in FIG. 9, in the slot n, the slot n+2, and the slot n+6, the base station schedules the PDSCH for transmitting the eMBB service, and the PRIs in the corresponding DCI are 000, 011, and 111, respectively. In the slot n+6 and the slot n+7, the base station schedules the PDSCH for transmitting the URLLC service, and the PRI in the corresponding DCI is 000. For the eMBB service, in the feedback window corresponding to the slot n+8, since the last DCI detected by the UE is the DCI corresponding to the PDSCH transmitted in the slot n+6, the DCI corresponding to the PDSCH transmitted in the slot n+6 is used. The PUCCH resource performs feedback. Since the number of feedback bits is greater than 2, the terminal uses the eighth PUCCH resource in the PUCCH resource set 2 (which is an eMBB-dedicated resource set) for feedback; for the URLLC service, in the slot n+6 and the slot In n+7, the C-DAI indications in the DCI corresponding to the two PDSCHs received by the UE are 1 and 2, respectively, and the PRI indications in the DCI are all 000, therefore, the slots n+6 and the slots n+7 The feedback information of the PDSCH of the URLLC service uses the first PUCCH resource set configured by the high layer signaling (ie, the resource set 1, which may be a URLLC-specific resource set, or the first PUCCH in the eMBB and the URLLC common resource set). Resource transfer.
情况B:如图10所示,在时隙n、时隙n+2和时隙n+6中,基站调度了传输eMBB业务的PDSCH,对应的DCI中PRI分别为000、011和111,在时隙n+6和时隙n+7中,基站调度了传输URLLC业务的PDSCH,对应的DCI中PRI分别为000和001。对于eMBB业务,在slot n+8对应的反馈窗内由于UE最后一个检测到的DCI为slot n+6中传输的PDSCH对应的DCI,因此使用slot n+6中传输的PDSCH对应的DCI指示的PUCCH资源进行反馈,由于反馈比特数大于2,则终端使用高层信令配置的第二个PUCCH资源集合(资源集合2,为eMBB专用的资源集合)中的第八个PUCCH资源进行反馈;对于URLLC业务,在时隙n+6和时隙n+7中,UE接收到两个PDSCH对应的DCI中的C-DAI指示均为1,而DCI中的PRI指示分别为000和001,因此,时隙n+6中PDSCH的反馈信息使用高层信令配置的PUCCH资源集合(可以是URLLC专用的资源集合,或者是eMBB和URLLC通用的资源集合)中的第一个PUCCH资源传输,时隙n+7中PDSCH的反馈信息使用高层信令配置的PUCCH资源集合中的第二个PUCCH资源传输。Case B: As shown in FIG. 10, in the slot n, the slot n+2, and the slot n+6, the base station schedules the PDSCH transmitting the eMBB service, and the PRIs in the corresponding DCI are 000, 011, and 111, respectively. In the slot n+6 and the slot n+7, the base station schedules the PDSCH for transmitting the URLLC service, and the PRIs in the corresponding DCI are 000 and 001, respectively. For the eMBB service, in the feedback window corresponding to the slot n+8, since the last DCI detected by the UE is the DCI corresponding to the PDSCH transmitted in the slot n+6, the DCI corresponding to the PDSCH transmitted in the slot n+6 is used. The PUCCH resource performs feedback. Since the number of feedback bits is greater than 2, the terminal uses the eighth PUCCH resource in the second PUCCH resource set (resource set 2, which is an eMBB dedicated resource set) configured by the high layer signaling to feed back; for URLLC For the service, in the slot n+6 and the slot n+7, the C-DAI indication in the DCI corresponding to the two PDSCHs received by the UE is 1, and the PRI indications in the DCI are 000 and 001, respectively. The feedback information of the PDSCH in the slot n+6 is transmitted using the PUCCH resource set configured by the higher layer signaling (which may be a URLLC-dedicated resource set or a resource set common to the eMBB and the URLLC), and the slot n+ The feedback information of the PDSCH in 7 is transmitted using the second PUCCH resource in the PUCCH resource set configured by the higher layer signaling.
本公开实施例的传输方法,通过仅配置一个PUCCH资源集合,且限制在同一个时隙中的同一个PUCCH资源上反馈的HARQ反馈信息对应的DCI包含的PRI相同,在同一个时隙中的不同PUCCH上传输的HARQ反馈信息对应的DCI包含的PRI不同,可以支持终端在一个slot内使用多个PUCCH传输HARQ反馈信息,使得终端能够确定同一时隙内的HARQ反馈信息是否在该时隙内的同一个PUCCH上传输,避免目前基站和终端之间出现对于反馈资源理解不一致的情况,特别是对于URLLC业务降低了HARQ反馈时延,从而提高了***的传输性能。The transmission method of the embodiment of the present disclosure is configured to configure only one PUCCH resource set, and the DCI corresponding to the HARQ feedback information corresponding to the feedback on the same PUCCH resource in the same time slot is the same as the PRI included in the same time slot. The DCI corresponding to the HARQ feedback information transmitted on different PUCCHs is different, and the terminal can support the terminal to use multiple PUCCHs to transmit HARQ feedback information in one slot, so that the terminal can determine whether the HARQ feedback information in the same time slot is in the time slot. The transmission on the same PUCCH avoids the situation that the understanding of the feedback resources is inconsistent between the current base station and the terminal, and in particular, the HARQ feedback delay is reduced for the URLLC service, thereby improving the transmission performance of the system.
