为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

首先对本申请涉及的几个名词进行介绍和解释：First, introduce and explain several terms involved in this application:

1、多时隙(时隙组)为单位的PDCCH检测能力定义1. Definition of PDCCH detection capability in units of multi-slots (slot groups)

高频操作中，对于SCS＝480/960KHz的信道，定义物理下行控制信道(Physical downlink control channel，PDCCH)检测能力以时隙组为单位，即以时隙组为单位，定义终端的检测能力。如：In high-frequency operation, for channels with SCS=480/960KHz, the detection capability of the physical downlink control channel (PDCCH) is defined in units of time slot groups, that is, the detection capabilities of terminals are defined in units of time slot groups. like:

表1 UE PDCCH检测能力定义(以时隙组为单位)Table 1 Definition of UE PDCCH detection capability (in slot group)

表1中PDCCH检测能力数值是假设的数值，可以为其它数，这里不做限制，包含时隙数M是整数，4/8/16也是示例，可以为其它数，这里不做限制。The PDCCH detection capability value in Table 1 is a hypothetical value, which can be other numbers, which is not limited here, including the number of time slots M is an integer, 4/8/16 is also an example, and can be other numbers, which is not limited here.

这里以SCS＝960，所有PDCCH的检测机会分布在时隙组的一个时隙为例，示意时隙组为单位的PDCCH检测能力(M＝8，即一个时隙组包含8个时隙)。Here, taking SCS=960, all PDCCH detection opportunities are distributed in one slot of a slot group as an example, to illustrate the PDCCH detection capability of a slot group (M=8, that is, a slot group includes 8 slots).

参见图1，其示例性地示出了本申请实施例的以时隙组为单位的PDCCH检测能力的示意图，如图所示，在8个时隙为一个时隙组中，只有第一个时隙配置了PDCCH检测时机，其它时隙上均没有PDCCH检测时机，即基站只会在第一个时隙上发送调度信息DCI，该DCI包含调度下行PDSCH和调度上行PUSCH。Referring to Fig. 1, it exemplarily shows a schematic diagram of the PDCCH detection capability in units of time slot groups according to the embodiment of the present application. As shown in the figure, in 8 time slots as a time slot group, only the first The time slot is configured with a PDCCH detection opportunity, and there is no PDCCH detection opportunity in other time slots, that is, the base station only sends scheduling information DCI in the first time slot, and the DCI includes scheduling downlink PDSCH and scheduling uplink PUSCH.

基于上述多时隙为单位的PDCCH检测能力定义，标准讨论支持1个DCI调度多个PUSCH/PDSCH，且多个PUSCH/PDSCH在时域上分布可以是不连续的。Based on the above-mentioned definition of PDCCH detection capability in units of multiple slots, the standard discussion supports one DCI to schedule multiple PUSCH/PDSCHs, and the distribution of multiple PUSCHs/PDSCHs in the time domain may be discontinuous.

2、HARQ-ACK动态码本(type-2)机制2. HARQ-ACK dynamic codebook (type-2) mechanism

在现有5G系统中，支持动态HARQ-ACK码本的生成机制，其原理是：在发送调度信令DCI时，增加DAI指示，终端侧根据DAI计数来计算基站实际发送DCI和PDSCH的数目，从而确定HARQ-ACK码本中包含的需要反馈的PDSCH数目。In the existing 5G system, the dynamic HARQ-ACK codebook generation mechanism is supported. The principle is: when sending the scheduling signaling DCI, add the DAI indication, and the terminal side calculates the number of DCI and PDSCH actually sent by the base station according to the DAI count. Therefore, the number of PDSCHs that need to be fed back included in the HARQ-ACK codebook is determined.

参见图2，其示例性地示出了本申请实施例的动态码本的示意图，如上图所示：基站调度了7个PDSCH给终端，调度信息中指示PUCCH反馈时隙位置在同一个时隙上，希望反馈7个PDSCH的HARQ-ACK信息(若每个PDSCH对应一个HARQ-ACK的bit反馈，则HARQ-ACK的码本是7)。由于无线信道的不确定性，DCI-5和DCI-6终端侧漏检，终端接收到调度信令DCI-7中的C-DAI＝3(对应比特信息指示为10)，上一次收到的DCI-4的C-DAI＝4.则终端可根据DAI数值，知道在DCI-4和DCI-7之间丢失了2个DCI，这样HARQ-ACK反馈的PDSCH总数，终端仍然可以计算出为7。Referring to Figure 2, it exemplarily shows a schematic diagram of the dynamic codebook of the embodiment of the present application, as shown in the above figure: the base station schedules 7 PDSCHs to the terminal, and the scheduling information indicates that the PUCCH feedback slot position is in the same slot Above, it is desired to feed back the HARQ-ACK information of 7 PDSCHs (if each PDSCH corresponds to one HARQ-ACK bit feedback, the HARQ-ACK codebook is 7). Due to the uncertainty of the wireless channel, the DCI-5 and DCI-6 terminals missed detection, the terminal received C-DAI=3 in the scheduling signaling DCI-7 (the corresponding bit information indicates 10), and the last received The C-DAI of DCI-4=4. Then the terminal can know that 2 DCIs are lost between DCI-4 and DCI-7 according to the DAI value. In this way, the total number of PDSCH fed back by HARQ-ACK can still be calculated as 7 by the terminal. .

在现有技术中，假设终端连续漏检的DCI个数不会超过3个，因此示例中的DAI采用2bit的信息指示，这里叫计数DAI(C-DAI，counter downlink assignment indicator)。In the prior art, it is assumed that the number of DCI missed by the terminal in a row will not exceed 3, so the DAI in the example uses 2-bit information indication, which is called count DAI (C-DAI, counter downlink assignment indicator).

另外：为了支持多载波的HARQ反馈，在C-DAI的基础上引入T-DAI(total DAI),采用2bit的信息指示，C-DAI和T-DAI联合使用，确定实际反馈的PDSCH的个数，从而确定HARQ-ACK的码本长度。In addition: In order to support multi-carrier HARQ feedback, T-DAI (total DAI) is introduced on the basis of C-DAI, using 2-bit information indication, C-DAI and T-DAI are used jointly to determine the number of PDSCHs actually fed back , so as to determine the codebook length of the HARQ-ACK.

3、上行DAI(UL DAI)3. Uplink DAI (UL DAI)

当DCI调度PUSCH时，其调度的PUSCH上有可能传输HARQ-ACK码本信息，为了让终端准确计算复用在PUSCH上的HARQ-ACK码本长度，在调度PUSCH的DCI中，增加了UL DAI的指示信息。终端计算HARQ码本时，使用UL DAI作为T-DAI计算HARQ码本的长度。When DCI schedules PUSCH, the HARQ-ACK codebook information may be transmitted on the scheduled PUSCH. In order for the terminal to accurately calculate the length of the HARQ-ACK codebook multiplexed on the PUSCH, UL DAI is added to the DCI for scheduling PUSCH. instructions for the . When calculating the HARQ codebook, the terminal uses UL DAI as the T-DAI to calculate the length of the HARQ codebook.

现有format 0_1的DCI中，携带了一份UL DAI信息，当该DCI调度多个PUSCH时，无法确定该UL DAI信息域应用的PUSCH的范围。参见图3，其示例性地示出了本申请实施例待解决问题的示意图，如图所示，当上行PUSCH调度信令DCI中包括UL DAI＝3，UE无法确定在哪个或者哪几个PUSCH发送总数为3的HARQ-ACK。The existing DCI of format 0_1 carries a piece of UL DAI information. When the DCI schedules multiple PUSCHs, it is impossible to determine the range of PUSCHs used in the UL DAI information field. Referring to FIG. 3, it exemplarily shows a schematic diagram of the problem to be solved in the embodiment of the present application. As shown in the figure, when the uplink PUSCH scheduling signaling DCI includes UL DAI=3, the UE cannot determine which or which PUSCH A total of 3 HARQ-ACKs are sent.

现有标准还没有给出当一个DCI调度多个PUSCH时，UL DAI信息的应用方法。The existing standard has not given the application method of UL DAI information when one DCI schedules multiple PUSCHs.

和问题场景比较类似的场景：一个DCI调度了一个PUSCH，且该PUSCH是重复发送时，UL DAI应用于UE准备做HARQ-ACK做复用的时隙上。A scenario similar to the problem scenario: when a DCI schedules a PUSCH, and the PUSCH is sent repeatedly, UL DAI is applied to the time slot where the UE prepares for HARQ-ACK multiplexing.

如果PUSCH传输在多个时隙上时，调度该DCI包含了一个DCI域，则该DAI域应于用UE准备做HARQ-ACK做复用的时隙上。If the DCI is scheduled to include a DCI field when the PUSCH is transmitted on multiple time slots, the DAI field should be used in the time slots for which the UE prepares to perform HARQ-ACK multiplexing.

需要说明的是：上述“准备做HARQ-ACK做复用的时隙”，理解为：终端根据下行PDSCH调度DCI确定的，即：如果终端收到PDSCH的调度DCI，则进行HARQ-ACK复用，如果终端没有收到PDSCH的调度DCI，则终端不进行HARQ-ACK复用(终端没有收到PDSCH的调度DCI分为两种情况：1：基站没有发送。2：基站发送了但终端漏检)It should be noted that the above-mentioned "time slot for preparing for HARQ-ACK multiplexing" is understood as: the terminal determines according to the downlink PDSCH scheduling DCI, that is, if the terminal receives the PDSCH scheduling DCI, it performs HARQ-ACK multiplexing , if the terminal does not receive the scheduling DCI of the PDSCH, the terminal does not perform HARQ-ACK multiplexing (the terminal does not receive the scheduling DCI of the PDSCH is divided into two cases: 1: the base station does not send it. 2: the base station sends it but the terminal misses detection )

参见图4，其示例性地示出了现有R15/R16的UL DAI时隙应用的示意图，如图所示，基站在发送了3个DCI，DCI-1调度了一个PDSCH，指示HARQ-ACK反馈在时隙n上，DCI-1调度了一个PDSCH，指示HARQ-ACK反馈在时隙n+2上；DCI-3调度了多个PUSCH，传输在时隙n/n+1/n+2/n+3上，且UL DAI＝1。基站希望在时隙n上，有1bit的HARQ-ACK在时隙n的PUSCH上传输，有1bit的HARQ-ACK在时隙n+2的PUSCH上传输。终端接收到了DCI-1和DCI-3，DCI-2漏检。则终端只在时隙n的PUSCH上反馈1bit的HARQ-ACK，在时隙n+2上不反馈任何HARQ-ACK信息。Referring to Figure 4, it schematically shows a schematic diagram of the existing R15/R16 UL DAI time slot application. As shown in the figure, the base station sends 3 DCIs, and DCI-1 schedules a PDSCH, indicating HARQ-ACK The feedback is on time slot n, and DCI-1 schedules a PDSCH, indicating that HARQ-ACK feedback is on time slot n+2; DCI-3 schedules multiple PUSCHs, and the transmission is on time slot n/n+1/n+2 /n+3 up, and UL DAI=1. The base station hopes that in time slot n, 1-bit HARQ-ACK is transmitted on the PUSCH of time slot n, and 1-bit HARQ-ACK is transmitted on the PUSCH of time slot n+2. The terminal received DCI-1 and DCI-3, and DCI-2 was missed. Then the terminal only feeds back 1-bit HARQ-ACK on the PUSCH of time slot n, and does not feed back any HARQ-ACK information on time slot n+2.

现有技术存在的问题在于，对于动态(Type-2)HARQ码本，出现DCI漏检的情况下，导致PUSCH接收错误。The problem existing in the prior art is that, for a dynamic (Type-2) HARQ codebook, in the case of missing DCI detection, a PUSCH reception error is caused.

参见图5，其示例性地示出了现有技术存在的问题的示意图，如上图所示，假设基站配置的动态HARQ码本反馈方式，假设DCI-1调度8个PDSCH，调度信令中k1指示为3，表示用于传输HARQ-ACK的PUCCH所在时隙。假设DCI-2调度了4个PUSCH(PUSCH0/1/2/3)，其中DCI-1指示的PUSCH0的时隙和PUCCH的时隙相同。Referring to Fig. 5, it exemplarily shows a schematic diagram of problems existing in the prior art. As shown in the above figure, assuming the dynamic HARQ codebook feedback mode configured by the base station, assuming that DCI-1 schedules 8 PDSCHs, k1 in the scheduling signaling The indication is 3, indicating the time slot of the PUCCH used to transmit the HARQ-ACK. It is assumed that DCI-2 schedules four PUSCHs (PUSCH0/1/2/3), wherein the time slot of PUSCH0 indicated by DCI-1 is the same as the time slot of PUCCH.

终端侧：假设终端丢失了DCI-1的调度信令，则按照现有R15的协议，终端不会在PUSCH-0上发送HARQ-ACK(按照编码速率1对PUSCH进行编码)。Terminal side: Assuming that the terminal loses the scheduling signaling of DCI-1, according to the existing R15 protocol, the terminal will not send HARQ-ACK on PUSCH-0 (code PUSCH according to coding rate 1).

导致的问题：在上述情况中，按照终端在PUSCH-0的复用HARQ-ACK的假设进行接收PUSCH，由于HARQ-ACK反馈的信息为8比特 (大于2比特)，则基站采用速率匹配的重新计算计算PUSCH传输资源和编码速率来接收PUSCH(如按照编码速率2对PUSCH进行解码)，此时导致PUSCH解码错误，Problems caused: In the above situation, the PUSCH is received based on the assumption that the terminal multiplexes HARQ-ACK on PUSCH-0. Since the information fed back by HARQ-ACK is 8 bits (more than 2 bits), the base station adopts rate-matched re- Calculate and calculate PUSCH transmission resources and coding rate to receive PUSCH (for example, decode PUSCH according to coding rate 2), which causes PUSCH decoding error at this time,

同样道理，对于静态HARQ-ACK码本生成方式，DCI漏检也会导致PUSCH解码错误。In the same way, for the static HARQ-ACK codebook generation method, DCI missing detection will also cause PUSCH decoding errors.

以上，如果PUSCH传输在多个时隙上时，调度该DCI包含了一个UL DAI域，则该DAI域基于UE接收PDSCH的DCI调度情况而确定(如：当UE接收到PDSCH的调度信令DCI时，且反馈的HARQ-ACK在相应的PUSCH时，UL DAI应用于该PUSCH，否则不应用)，当存在如下DCI调度丢失的场景时，导致PUSCH解调失败：Above, if the PUSCH is transmitted on multiple time slots, the scheduled DCI includes a UL DAI field, and the DAI field is determined based on the DCI scheduling situation of the UE receiving the PDSCH (for example: when the UE receives the PDSCH scheduling signaling DCI , and the feedback HARQ-ACK is on the corresponding PUSCH, UL DAI is applied to the PUSCH, otherwise it is not applied), when the following DCI scheduling loss scenarios exist, PUSCH demodulation fails:

1：在相应的PUSCH上，反馈1个DCI调度的PDSCH的HARQ-ACK反馈。该DCI调度了3个及以上的PDSCH，且终端漏检该DCI。1: Feedback the HARQ-ACK feedback of one DCI-scheduled PDSCH on the corresponding PUSCH. The DCI schedules 3 or more PDSCHs, and the terminal misses detecting the DCI.

2：在相应的PUSCH上，反馈2个DCI调度的PDSCH的HARQ-ACK反馈。该两个DCI调度PDSCH的DCI个数之和大于等于3，且终端漏检该两个DCI。2: Feed back the HARQ-ACK feedback of two DCI-scheduled PDSCHs on the corresponding PUSCH. The sum of the number of DCIs of the PDSCH scheduled by the two DCIs is greater than or equal to 3, and the terminal misses detection of the two DCIs.

3：在相应的PUSCH上，反馈3个DCI调度的PDSCH的HARQ-ACK反馈。该三个DCI调度PDSCH的DCI个数之和大于等于3，且终端漏检该三个DCI。3: On the corresponding PUSCH, feed back the HARQ-ACK feedback of the three DCI-scheduled PDSCHs. The sum of the number of DCIs of the PDSCH scheduled by the three DCIs is greater than or equal to 3, and the terminal misses detection of the three DCIs.

参见图7，其示例性地示出了本申请实施例的通信方法的流程示意图，该通信方法应用于基站，如图所示，该方法包括：Referring to FIG. 7, it exemplarily shows a schematic flowchart of a communication method in an embodiment of the present application. The communication method is applied to a base station. As shown in the figure, the method includes:

S101、向UE指示当一个DCI调度多个物理上行共享信道PUSCH且DCI中包括UL DAI时，UL DAI作用的PUSCH范围；S101. Indicate to the UE that when one DCI schedules multiple physical uplink shared channels PUSCH and the DCI includes UL DAI, the PUSCH range on which the UL DAI acts;

S102、向UE发送至少一个用于调度PUSCH的DCI。S102. Send at least one DCI for scheduling the PUSCH to the UE.

应当理解的是，UE在接收到用于调度PUSCH的DCI后，即在指示的PUSCH范围内的PUSCH上发送HARQ-ACK消息。本申请实施例通过指示多PUSCH调度场景下UL DAI应用的PUSCH范围，对于应用UL DAI的PUSCH，终端需要根据UL DAI生成HARQ-ACK码本，无论UE是否接收到相应的下行PDSCH调度DCI。从而避免在每个PUSCH都进行HARQ-ACK反馈，且避免终端侧因漏检下行PDSCH调度而造成的PUSCH发送错误，提高了HARQ-ACK反馈效率。It should be understood that, after receiving the DCI for scheduling the PUSCH, the UE sends the HARQ-ACK message on the PUSCH within the indicated PUSCH range. In the embodiment of the present application, by indicating the PUSCH range of UL DAI application in the multi-PUSCH scheduling scenario, for the PUSCH applying UL DAI, the terminal needs to generate a HARQ-ACK codebook according to the UL DAI, regardless of whether the UE receives the corresponding downlink PDSCH scheduling DCI. In this way, HARQ-ACK feedback is avoided on each PUSCH, and PUSCH transmission errors caused by missed detection of downlink PDSCH scheduling at the terminal side are avoided, and HARQ-ACK feedback efficiency is improved.

在上述各实施例的基础上，作为一种可选实施例，本申请实施例向用户设备指示当一个DCI调度多个PUSCH且DCI中包括UL DAI时，UL DAI作用的PUSCH范围，包括：On the basis of the above embodiments, as an optional embodiment, the embodiment of the present application indicates to the user equipment that when one DCI schedules multiple PUSCHs and the DCI includes UL DAI, the PUSCH range that UL DAI acts on includes:

本申请实施例可以通过高层信令状态组合指示，实现高层信令配置。具体地，通过高层信令配置的方式向UE指示当一个DCI调度多个PUSCH且DCI中包括UL DAI时，UL DAI作用的PUSCH范围，包括：In this embodiment of the present application, high-level signaling configuration can be realized by combining high-level signaling state indications. Specifically, when a DCI schedules multiple PUSCHs and the DCI includes UL DAI, the range of PUSCHs that UL DAI acts on is indicated to the UE through high-layer signaling configuration, including:

本实施例是基站通过高层信令配置，采用状态组合指示的方法,确定当一个DCI调度多个PUSCH时，UL DAI作用PUSCH范围。In this embodiment, the base station determines the PUSCH range that UL DAI acts on when one DCI schedules multiple PUSCHs through high-level signaling configuration and using a state combination indication method.

指示UL DAI作用PUSCH的范围，状态数为N个(N大于等于1)，每种状态表示一种UL DAI作用PUSCH的范围。下面以N＝4为例，请参见表2：Indicates the range of UL DAI acting on PUSCH, the number of states is N (N is greater than or equal to 1), and each state represents a range of UL DAI acting on PUSCH. Take N=4 as an example below, see Table 2:

表2状态指示表Table 2 Status Indication Table

上表中，X表示DCI调度的PUSCH个数，M为大于1的整数，比如PDCCH检测时隙组包含时隙个数。另外也可以将PUSCH限制为有效的PUSCH，有效是指终端去掉一些无法发送的PUSCH，剩下能够发送的PUSCH(如：调度PUSCH包含下行符号)。另外，上述条件中，也可以设定X<＝M/2或者X>M/2。In the above table, X represents the number of PUSCHs scheduled by the DCI, and M is an integer greater than 1. For example, the PDCCH detection slot group includes the number of slots. In addition, the PUSCH can also be limited to valid PUSCHs, which means that the terminal removes some untransmittable PUSCHs and leaves the PUSCHs that can be transmitted (for example, the scheduled PUSCHs include downlink symbols). In addition, among the above conditions, X<=M/2 or X>M/2 may be set.

假设上述N＝4的状态中，基站指示为状态1，也即确定目标状态值为0，则终端接收到多个PUSCH调度时，如果包含有1份UL DAI，则只在第1个有效的PUSCH上传输HARQ-ACK信息，即将HARQ-ACK复用到PUSCH上。Assuming that in the above state of N=4, the base station indicates state 1, that is, the determined target state value is 0, then when the terminal receives multiple PUSCH scheduling, if it contains 1 UL DAI, only the first effective The HARQ-ACK information is transmitted on the PUSCH, that is, the HARQ-ACK is multiplexed on the PUSCH.

如图8所示，其示例性地示出了本申请实施例通过高层信令状态指示确定UL DAI作用的PUSCH范围的应用场景示意图，假设基站配置的动态HARQ码本反馈方式，DCI-0调度8个PDSCH，调度信令中k1指示为3，表示用于传输HARQ-ACK的PUCCH所在时隙。假设DCI-1调度了4个PUSCH(PUSCH0/1/2/3),其中DCI-1指示的PUSCH0的时隙和PUCCH的时隙相同，HARQ-ACK信息需要在PUSCH-0上传输，HARQ-ACK信息的长度用DCI-1中的UL DAI计算。As shown in Figure 8, it exemplarily shows a schematic diagram of an application scenario in which the PUSCH range of UL DAI is determined through high-level signaling status indication in the embodiment of the present application, assuming the dynamic HARQ codebook feedback mode configured by the base station, DCI-0 scheduling There are 8 PDSCHs, and k1 indicates 3 in the scheduling signaling, indicating the time slot where the PUCCH used to transmit HARQ-ACK is located. Suppose DCI-1 schedules 4 PUSCHs (PUSCH0/1/2/3), where the time slot of PUSCH0 indicated by DCI-1 is the same as the time slot of PUCCH, HARQ-ACK information needs to be transmitted on PUSCH-0, HARQ- The length of ACK information is calculated by UL DAI in DCI-1.

对于终端侧，终端漏检了DCI-0，但由于DCI-1中指示UL DAI＝1且根据高层信令配置获知UL CAI的作用范围为第一个PUSCH，也即PUSCH0，则终端依然根据UL DAI在PUSCH-0上传输8bit的HARQ-ACK信息，确保PUSCH-0按照预期的码率进行发送和接收。For the terminal side, the terminal misses DCI-0, but since DCI-1 indicates UL DAI = 1 and according to high-level signaling configuration, it knows that the scope of UL CAI is the first PUSCH, that is, PUSCH0, DAI transmits 8-bit HARQ-ACK information on PUSCH-0 to ensure that PUSCH-0 is sent and received according to the expected code rate.

当上述表格中的内容通过高层信令配置时，其指示UL DAI作用PUSCH的范围，当高层信令没有配置时，可表示成另外一种指示含义(即默认指示方式)。When the content in the above table is configured through high-level signaling, it indicates the scope of UL DAI for PUSCH. When the high-level signaling is not configured, it can be expressed as another indication meaning (ie, the default indication mode).

如：假设高层信令状态组合被定义在PUSCH配置信息中，且为可选项，示意如下：For example: Assume that the high-level signaling state combination is defined in the PUSCH configuration information and is optional, as shown below:

PUSCH-ConfigCommon::＝SEQUENCE{//PUSCH配置信息PUSCH-ConfigCommon::=SEQUENCE{//PUSCH configuration information

pusch-TimeDomainAllocationList OPTIONAL//PUSCH的时域调度参数表，可选项pusch-TimeDomainAllocationList OPTIONAL//PUSCH time domain scheduling parameter list, optional

ULDAIApplyPUSCHstateindication OPTIONAL//状态组合指示,可选项ULDAIApplyPUSCHstateindication OPTIONAL//state combination indication, optional

}}

状态组合指示(ULDAIApplyPUSCHstateindication)只定义了1状态，且表示为“作用于1个PUSCH，且为最后1个有效PUSCH”。The state combination indication (ULDAIApplyPUSCHstateindication) only defines 1 state, and is expressed as "acting on 1 PUSCH, and being the last valid PUSCH".

如果实际执行过程中，配置了则表示“UL DAI作用于1个PUSCH，且为最后1个有效PUSCH”，如果没有配置可以表示为另外一种指示含义，例如为“作用于1个PUSCH，且为第1个有效PUSCH”。If it is configured in the actual execution process, it means "UL DAI acts on 1 PUSCH, and it is the last valid PUSCH". It is the first valid PUSCH".

在上述各实施例的基础上，对于除USCH应用范围之外的PUSCH，如果收到了相应的PDSCH的DCI，且指示HARQ-ACK信息在这些PUSCH上传输，则终端可使用下述任何一种方法(可由协议配置)：On the basis of the above-mentioned embodiments, for PUSCHs other than the USCH application range, if the DCI of the corresponding PDSCH is received and HARQ-ACK information is indicated to be transmitted on these PUSCHs, the terminal can use any of the following methods (configurable by protocol):

-使用调度PUSCH的DCI中的UL DAI计算HARQ-ACK反馈信息- Calculate HARQ-ACK feedback information using UL DAI in DCI that schedules PUSCH

-使用调度PDSCH的DCI中的DAI计算HARQ-ACK反馈信息。- Calculate HARQ-ACK feedback information using DAI in DCI scheduling PDSCH.

在上述各实施例的基础上，上述高层信令状态指示，可以通过广播消息、RRC消息或者MAC-CE消息发送至UE，本申请实施例不做具体的限定。On the basis of the above-mentioned embodiments, the above-mentioned high-level signaling status indication may be sent to the UE through a broadcast message, an RRC message or a MAC-CE message, which is not specifically limited in this embodiment of the present application.

在上述各实施例的基础上，作为一种可选实施例，通过高层信令配置的方式向UE指示当一个DCI调度多个PUSCH且DCI中包括UL DAI时， UL DAI作用的PUSCH范围，包括：On the basis of the above-mentioned embodiments, as an optional embodiment, when a DCI schedules multiple PUSCHs and the DCI includes UL DAI, the PUSCH range that UL DAI acts on is indicated to the UE through high-layer signaling configuration, including :

将比特位图作为高层信令配置的参数，发送至UE；Send the bitmap to the UE as a parameter configured by high-level signaling;

具体地，根据预定义的比特位图中的每个比特位指示对应的PUSCH是否属于UL DAI作用的PUSCH范围，包括：Specifically, each bit in the predefined bitmap indicates whether the corresponding PUSCH belongs to the PUSCH range for UL DAI, including:

本申请实施例指示UL DAI作用PUSCH的范围，可采用比特位图N，其中N等于一个DCI调度PUSCH的最大个数(如N＝8)，每个比特位对应一个调度的PUSCH，“1”表示作用于该PUSCH，“0”表示不作用于该PUSCH，或者相反。The embodiment of the present application indicates the scope of UL DAI acting on PUSCH, and the bitmap N can be used, where N is equal to the maximum number of PUSCHs scheduled by a DCI (such as N=8), and each bit corresponds to a scheduled PUSCH, "1" It means to act on the PUSCH, "0" means not to act on the PUSCH, or vice versa.

下面以N＝8为例。例如，当比特位图为1,0,0,0,0,0,0,0时，表示UL DAI作用于1个PUSCH，且为第1个PUSCH；当比特位图为0,0,0,0,0,0,0,1时，表示UL DAI作用于1个PUSCH，且为最后1个PUSCH；当比特位图为0,1,0,0,0,0,0,0时，表示UL DAI作用于1个PUSCH，且为第2个PUSCH；当比特位图为1,0,0,0,1,0,0,0时，表示UL DAI作用于1或者2个PUSCH：Take N=8 as an example below. For example, when the bitmap is 1,0,0,0,0,0,0,0, it means that UL DAI acts on 1 PUSCH, and it is the first PUSCH; when the bitmap is 0,0,0 ,0,0,0,0,1, it means that UL DAI acts on 1 PUSCH, and it is the last PUSCH; when the bitmap is 0,1,0,0,0,0,0,0, Indicates that UL DAI acts on 1 PUSCH, and it is the second PUSCH; when the bitmap is 1,0,0,0,1,0,0,0, it indicates that UL DAI acts on 1 or 2 PUSCHs:

--当X<＝M/2时，UL DAI应用在第1个调度的PUSCH-- When X<=M/2, UL DAI is applied to the first scheduled PUSCH

--当X>M/2时，UL DAI应用在第1和第(1+M/2)调度的有效PUSCH--When X>M/2, UL DAI applies to the effective PUSCH scheduled in the 1st and (1+M/2)th

其中，M为大于1的整数。Wherein, M is an integer greater than 1.

如图9所示，其示例性地示出了本申请实施例通过高层信令比特位图确定UL DAI作用的PUSCH的应用场景示意图，如图所示，假设基站配置的动态HARQ码本反馈方式，假设DCI-0调度4个PDSCH，调度信令中k1指示为8，表示用于传输HARQ-ACK的PUCCH所在时隙。假设DCI-1调度4个PDSCH，调度信令中k1指示为7，表示用于传输HARQ-ACK的PUCCH所在时隙。假设DCI-1调度了6个PUSCH (PUSCH0/1/2/3/4/5),则终端在PUSCH0和PUSCH4上使用UL-DAI。As shown in Figure 9, it exemplarily shows a schematic diagram of the application scenario of PUSCH determining the role of UL DAI through the high-level signaling bitmap in the embodiment of the present application. As shown in the figure, it is assumed that the dynamic HARQ codebook feedback method configured by the base station , assuming that DCI-0 schedules 4 PDSCHs, and k1 indicates 8 in the scheduling signaling, indicating the time slot where the PUCCH used to transmit HARQ-ACK is located. Assuming that DCI-1 schedules 4 PDSCHs, k1 indicates 7 in the scheduling signaling, indicating the time slot where the PUCCH used to transmit HARQ-ACK is located. Assuming that DCI-1 schedules 6 PUSCHs (PUSCH0/1/2/3/4/5), the terminal uses UL-DAI on PUSCH0 and PUSCH4.

另外，假设终端漏检了DCI-1，但由于DCI-1中指示UL DAI＝1并且根据比特位图获知PUSCH作用范围，则终端依然根据UL DAI在PUSCH-4上传输4bit的HARQ-ACK信息。确保PUSCH-4按照预期的码率进行发送和接收。In addition, assuming that the terminal misses DCI-1, but since DCI-1 indicates UL DAI=1 and the PUSCH scope is known according to the bitmap, the terminal still transmits 4-bit HARQ-ACK information on PUSCH-4 according to UL DAI . Make sure that PUSCH-4 is sent and received at the expected code rate.

另外：当UL DAI的使用作用于两个或者两个以上PUSCH时，实施例中假设DCI中只有一份UL DAI，标准上，也可以在DCI中指示2份或者2份以上的UL DAI，可以分别对应到相应的PUSCH上，这里不做约束。In addition: when the use of UL DAI is applied to two or more PUSCHs, it is assumed in the embodiment that there is only one UL DAI in the DCI. According to the standard, 2 or more UL DAIs can also be indicated in the DCI. correspond to the corresponding PUSCH respectively, and there is no constraint here.

需要注意的是，当上述表格内容通过高层信令配置时，其指示UL DAI作用PUSCH的范围，当高层信令没有配置时，可表示成另外一种指示含义(即默认指示方式)。It should be noted that when the content of the above table is configured through high-level signaling, it indicates the scope of UL DAI for PUSCH. When the high-level signaling is not configured, it can be expressed as another indication meaning (ie, the default indication mode).

如：假设高层信令比特位图被定义在PUSCH配置信息中，且为可选项，示意如下：For example: Assume that the high-level signaling bitmap is defined in the PUSCH configuration information and is optional, as shown below:

ValidPuschWithinGroup BIT STRING(b0,b1,b2,b3,b4,b5,b6,b7)OPTIONAL//比特位图，可选项ValidPuschWithinGroup BIT STRING(b0,b1,b2,b3,b4,b5,b6,b7)OPTIONAL//bit map, optional

}}

如果没有配置可以表示为另外一种含义，如UL DAI无效，即不作用于任何PUSCH上，此时DCI中的UL DAI可以表示成其它的含义(如PUSCH的信道编码的版本信息，HARQ进程信息等)。If there is no configuration, it can be expressed as another meaning, such as UL DAI is invalid, that is, it does not act on any PUSCH. At this time, UL DAI in DCI can be expressed as other meanings (such as PUSCH channel coding version information, HARQ process information wait).

对于除本实施例指示的应用UL DAI的特定PUSCH之外的PUSCH，如果收到了相应的PDSCH的DCI，且指示HARQ-ACK信息在这些PUSCH上传输，则终端可使用下述任何一种方法(可由协议配置)：For PUSCHs other than the specific PUSCHs that apply UL DAI indicated in this embodiment, if the DCI of the corresponding PDSCH is received and HARQ-ACK information is indicated to be transmitted on these PUSCHs, the terminal can use any of the following methods ( configurable by protocol):

-丢弃PUSCH，或者丢弃需要传输的HARQ-ACK信息- Discard PUSCH, or discard HARQ-ACK information that needs to be transmitted

-终端认为同时收到的PUSCH调度信息和HARQ-ACK指示信息非法(即终端不希望收到该调度信令)。- The terminal considers that the PUSCH scheduling information and the HARQ-ACK indication information received at the same time are illegal (that is, the terminal does not want to receive the scheduling signaling).

上述高层信令可以通过广播消息、RRC消息或者MAC-CE消息发送至UE，这里不做限定。The above-mentioned high-level signaling may be sent to the UE through a broadcast message, an RRC message or a MAC-CE message, which is not limited here.

在上述各实施例的基础上，作为一种可选实施例，向用户设备UE指示当一个DCI调度多个PUSCH且DCI中包括UL DAI时，UL DAI作用的PUSCH范围，包括：On the basis of the above-mentioned embodiments, as an optional embodiment, when one DCI schedules multiple PUSCHs and the DCI includes UL DAI, the PUSCH range that UL DAI acts on is indicated to the user equipment UE, including:

在接口规范协议中定义第三接口规范协议信息，第三接口规范协议信息用于指示当DCI调度的PUSCH个数大于PDCCH检测时隙组包含的时隙个数M时，UL DAI应用在第1个和第M+1个调度的PUSCH；The third interface specification protocol information is defined in the interface specification protocol. The third interface specification protocol information is used to indicate that when the number of PUSCH scheduled by DCI is greater than the number M of time slots contained in the PDCCH detection time slot group, UL DAI is applied in the first and the M+1th scheduled PUSCH;

第三接口规范协议信息还可以指示：The third interface specification protocol information may also indicate:

当一个DCI调度多个PUSCH时，且该DCI包含DAI信息，DAI数值用于“第1个PUSCH”进行HARQ-ACK信息复用。When one DCI schedules multiple PUSCHs, and the DCI contains DAI information, the DAI value is used for "the first PUSCH" to multiplex HARQ-ACK information.

如果该DCI调度的PUSCH个数大于M，DAI数值还作用于第M+1 个PUSCH”进行HARQ-ACK信息复用。If the number of PUSCHs scheduled by the DCI is greater than M, the DAI value is also applied to the M+1th PUSCH" for HARQ-ACK information multiplexing.

数值M为大于1的整数，另外也可以和PDCCH检测能力相关。The value M is an integer greater than 1, and may also be related to the PDCCH detection capability.

对于除本申请实施例指示的应用UL DAI的PUSCH之外的PUSCH，如果收到了相应的PDSCH的DCI，且指示HARQ-ACK信息在这些PUSCH上传输，则终端可使用下述任何一种方法(可由协议配置)：For PUSCHs other than the PUSCH that applies UL DAI indicated in the embodiment of this application, if the DCI of the corresponding PDSCH is received and HARQ-ACK information is indicated to be transmitted on these PUSCHs, the terminal can use any of the following methods ( configurable by protocol):

-丢弃PUSCH，或者丢弃需要传输的HARQ-ACK信息。- discarding the PUSCH, or discarding the HARQ-ACK information to be transmitted.

当比特位图为1,0,0,0,1,0,0,0时，表示UL DAI作用于1或者2个PUSCH：When the bitmap is 1,0,0,0,1,0,0,0, it means that UL DAI acts on 1 or 2 PUSCHs:

--当X>M/2时，UL DAI应用在第1和第(1+M/2)调度的有效PUSCH。--When X>M/2, UL DAI applies the effective PUSCH scheduled at the 1st and (1+M/2)th.

需要说明的是，新增信息比特位的长度，可以小于PUSCH的最大个数。It should be noted that the length of the newly added information bits may be smaller than the maximum number of PUSCHs.

在上述各实施例的基础上，在DCI中设置指示UL DAI作用的PUSCH范围的信息，包括：On the basis of the above-mentioned embodiments, the information indicating the PUSCH range of the UL DAI role is set in the DCI, including:

假设一个DCI最多调度的PUSCH个数为max_PUSCH,在DCI中新增长度为比特的信息域，用于指示UL DAI应用于哪一个PUSCH。Assuming that the maximum number of PUSCHs scheduled by a DCI is max_PUSCH, an information field of length 1 bit is added in the DCI to indicate which PUSCH the UL DAI is applied to.

max_PUSCH＝8的示例如下：An example of max_PUSCH=8 is as follows:

000表示调度的第1个PUSCH应用UL DAI；000 means that the first scheduled PUSCH applies UL DAI;

001表示调度的第2个PUSCH应用UL DAI；001 means that the second scheduled PUSCH applies UL DAI;

010表示调度的第3个PUSCH应用UL DAI；010 means that the third scheduled PUSCH applies UL DAI;

以此类推。and so on.

需要说明的是，新增信息比特位的长度，可以小于

It should be noted that the length of the newly added information bits can be less than

新增可变长度信息域，在DCI中设置指示UL DAI作用的PUSCH范围的信息，包括：A new variable-length information field is added, and the information indicating the PUSCH range of UL DAI is set in the DCI, including:

需要说明的是，在1个DCI调度2个及以上PUSCH调度时，每个PUSCH的RV版本NDI指示都是使用1比特指示(RV版本；信道编码冗余版本号，NDI：新数据指示)，同时为了保持每次调度信息DCI的长度信息不变，所有PUSCH的RV比特信息固定为能够调度PUSCH个数的最大值max_PUSCH(如max_PUSCH＝8)。当实际调度的PUSCH个数M小于N时(如max_PUSCH＝4)，只使用前M个bit信息，后max_PUSCH-M个比特不使用。It should be noted that when one DCI schedules two or more PUSCHs, the RV version NDI indication of each PUSCH uses a 1-bit indication (RV version; channel coding redundancy version number, NDI: new data indication), At the same time, in order to keep the length information of each scheduling information DCI unchanged, the RV bit information of all PUSCHs is fixed to the maximum value max_PUSCH (eg max_PUSCH=8) of the number of PUSCHs that can be scheduled. When the number M of actually scheduled PUSCHs is less than N (for example, max_PUSCH=4), only the first M bits of information are used, and the last max_PUSCH-M bits are not used.

本实施例中，动态调度PUSCH个数小于最大个数时，利用没有被使用的RV或者NDI、RV和NDI来指示UL DAI应用PUSCH的范围。In this embodiment, when the number of dynamically scheduled PUSCHs is less than the maximum number, the unused RV or NDI, RV and NDI are used to indicate the scope of the UL DAI application PUSCH.

具体方法如下：The specific method is as follows:

假设：基站配置的1个DCI最多调度的PUSCH个数为max_PUSCH,终端接收到一个DCI调度信息时，实际调度PUSCH的个数为act_PUSCH。终端和基站确定UL DAI数值应用PUSCH的过程如下：Assumption: the maximum number of PUSCHs scheduled by one DCI configured by the base station is max_PUSCH, and when the terminal receives a DCI scheduling information, the number of actually scheduled PUSCHs is act_PUSCH. The process of terminal and base station determining UL DAI value and applying PUSCH is as follows:

-如果调度PUSCH个数等于max_PUSCH时，采用高层信令或者协议确定的方法,确定应用PUSCH范围；- If the number of scheduled PUSCHs is equal to max_PUSCH, use the method determined by high-level signaling or protocol to determine the application PUSCH range;

-如果调度PUSCH个数小于max_PUSCH，则使用不超过(max_PUSCH-act_PUSCH)*2比特数指示UL DAI使用的PUSCH范围。下面举例两个示例来进行说明。- If the number of scheduled PUSCHs is less than max_PUSCH, use no more than (max_PUSCH-act_PUSCH)*2 bits to indicate the PUSCH range used by UL DAI. Two examples are given below for illustration.

以max_PUSCH＝8，act_PUSCH＝7为例，由上述NDI和RV的背景内容可知：NDI和RV各有1比特信息位没有被使用(如：RV[7]，NDI[7]，即总共有2比特信息空余。则基站和终端使用2比特信息表示UL DAI的应用方位，如表3：Taking max_PUSCH=8, act_PUSCH=7 as an example, it can be seen from the background content of the above-mentioned NDI and RV: NDI and RV each have 1 bit of information that is not used (such as: RV[7], NDI[7], that is, there are 2 The bit information is vacant. The base station and the terminal use 2-bit information to indicate the application direction of UL DAI, as shown in Table 3:

表3第一DCI信息域表Table 3 The first DCI information domain table

也就是说，当利用RV和NDI中的1比特信息位记录00时，表示调度的第1个PUSCH应用UL DAI；当利用RV和NDI中的1比特信息位记录01时，表示调度的第2个PUSCH应用UL DAI；当利用RV和NDI中的1比特信息位记录10时，表示调度的第3个PUSCH应用UL DAI；当利用RV和NDI中的1比特信息位记录11时，表示调度的第4个PUSCH应用UL DAI。That is to say, when using 1-bit information bit in RV and NDI to record 00, it means that the first scheduled PUSCH applies UL DAI; when using 1-bit information bit in RV and NDI to record 01, it means that the scheduled second PUSCH The first PUSCH applies UL DAI; when using the 1-bit information bit in RV and NDI to record 10, it means that the scheduled third PUSCH applies UL DAI; when using the 1-bit information bit in RV and NDI to record 11, it means scheduling The 4th PUSCH applies UL DAI.

以max_PUSCH＝8，act_PUSCH＝4为例，NDI和RV各有4比特信息位没有被使用，即总共有8比特信息空余。则基站和终端可使用RV或者NDI中的4比特信息表示UL DAI的应用范围，如表4：Taking max_PUSCH=8 and act_PUSCH=4 as an example, 4 information bits of NDI and RV are not used respectively, that is, 8 bits of information are vacant in total. Then the base station and terminal can use the 4-bit information in RV or NDI to indicate the application range of UL DAI, as shown in Table 4:

表4第二DCI信息域表Table 4 Second DCI information domain table

以表4中的RV[4]为例，RV的第4个比特位可以表示第1个PUSCH是否应用UL DAI，例如当该比特位为0时，表示第1个PUSCH不应用UL DAI，当为1时，表示第1个PUSCH应用UL DAI。Taking RV[4] in Table 4 as an example, the fourth bit of RV can indicate whether the first PUSCH applies UL DAI. For example, when the bit is 0, it means that the first PUSCH does not apply UL DAI. When When it is 1, it means that the first PUSCH applies UL DAI.
