Therefore, the DCI scheduling The flexibility is poor, so the accuracy of the resource indicated in the UE transmission process is poor.

下面对本申请实施例提供的DCI调度方法、设备及***中涉及的一些概念和/或术语做一下解释说明。The following explains some concepts and/or terms involved in the DCI scheduling method, device, and system provided in the embodiments of the present application.
多发送接收点(TRP)传输技术：多TRP传输可以增加传输的可靠性或吞吐量性能，例如UE可以接收来自于多个TRP的相同数据或不同数据。Multi-transmit-receive-point (TRP) transmission technology: Multi-TRP transmission can increase the reliability or throughput performance of the transmission. For example, the UE can receive the same data or different data from multiple TRPs.
多TRP下行URLLC传输增强方案：Multi-TRP downlink URLLC transmission enhancement scheme:
方案1、空分复用(space division multiplexing，SDM)：一个时隙内指示n(n≤Ns) 个传输配置标识(transmission configuration indicator，TCI)状态，传输机会(transmission occasion)之间的时频资源完全交叠。其中，每次传输机会均为同一个(transport block，TB)的一层或多层集合，上述一层或多层集合关联到一个TCI状态和一个解调参考信号(demodulation reference signal，DMRS)端口或端口集合；采用一个冗余版本(redundancy version，RV)的单编码码字映射到所有的空间层或层集合上。从UE角度看，采用与Rel-15相同的映射规则将不同的编码比特映射到不同的层或层集合上。 Solution 1. Space division multiplexing (SDM): indicates the status of n (n≤Ns) transmission configuration indicators (TCI) in a time slot, and the time and frequency between transmission opportunities (transmission occasions) Resources completely overlap. Among them, each transmission opportunity is the same (transport block, TB) one or more layers set, the above one or more layer sets are associated with a TCI state and a demodulation reference signal (demodulation reference signal, DMRS) port Or port set; a redundancy version (RV) single-encoded codeword is mapped to all spatial layers or layer sets. From the perspective of the UE, the same mapping rules as Rel-15 are used to map different coded bits to different layers or layer sets.
方案2、频分复用(frequency division multiplexing，FDM)：一个时隙内指示n(n≤Ns)个TCI状态，传输机会(transmission occasion)之间的频域资源没有交叠。其中，每个无交叠的频域资源关联到一个TCI状态；所有无交叠的频域资源均关联到相同的一个/多个DMRS端口；所有资源传输采用一个RV的单编码码字。从UE角度看，采用与Rel-15相同的码字到层的映射规则映射到所有资源上。每个非交叠频域资源传输采用一个RV的单编码码字。对应于每个非交叠频域资源上的RV可以相同或不同。 Scheme 2. Frequency division multiplexing (FDM): n (n≤Ns) TCI states are indicated in a time slot, and frequency domain resources between transmission opportunities are not overlapped. Among them, each non-overlapping frequency domain resource is associated with a TCI state; all non-overlapping frequency domain resources are associated with the same one/multiple DMRS ports; all resource transmission adopts a single code word of RV. From the perspective of the UE, the same codeword-to-layer mapping rule as Rel-15 is used to map all resources. Each non-overlapping frequency domain resource transmission uses a single-coded codeword of RV. The RV corresponding to each non-overlapping frequency domain resource may be the same or different.
方案3、时分复用(time division multiplexing，TDM)：一个时隙内指示n(n≤Nt1)个TCI状态，时域资源没有交叠。其中，每次传输机会发送的TB对应一个TCI状态和一个RV，传输机会以微时隙(mini-slot)的时域粒度传输；一个时隙内的所有传输机会均采用相同MCS和相同的一个或多个DMRS端口；多次传输机会可以使用相同或不同的RV/TCI状态。 Scheme 3. Time division multiplexing (TDM): n (n≤Nt1) TCI states are indicated in a time slot, and time domain resources are not overlapped. Among them, the TB sent by each transmission opportunity corresponds to a TCI state and an RV, and the transmission opportunity is transmitted at the time domain granularity of mini-slot; all transmission opportunities in a time slot use the same MCS and the same one. Or multiple DMRS ports; multiple transmission opportunities can use the same or different RV/TCI status.
方案4、时分复用(TDM)：K个时隙指示n(n≤K)个TCI状态。其中，每次传输机会发送的TB对应一个TCI状态和一个RV；K个时隙内的所有传输机会均采用相同MCS和相同的一个或多个DMRS端口；多次传输机会可以使用相同或不同的RV/TCI状态。Scheme 4. Time division multiplexing (TDM): K time slots indicate n (n≤K) TCI states. Among them, the TB sent for each transmission opportunity corresponds to a TCI state and an RV; all transmission opportunities in K time slots use the same MCS and the same one or more DMRS ports; multiple transmission opportunities can use the same or different RV/TCI status.
PDSCH的接收处理时间：UE在接收到调度PDSCH的DCI后，会在DCI指示的时隙上接收PDSCH，并根据K1确定反馈该PDSCH对应的混合自动重传请求-确认(hybrid automatic repeat request-acknowledgement，HARQ-ACK)的物理上行控制信道(physical uplink control channel，PUCCH)所在的时隙，其中K1为根据该下行DCI中包含的PDSCH与HARQ反馈定时指示(PDSCH-to-HARQ feedback timing indicator)或高层参数(dl-Data To UL-ACK)得到的反馈HARQ-ACK的PUCCH与PDSCH之间的时隙偏移数。如果UE发送HARQ-ACK的PUCCH的第一个上行OFDM符号不早于OFDM符号L 1，L 1定义为 传输TB的PDSCH的最后一个OFDM符号之后的T proc,1，UE则上报有效的HARQ-ACK。 PDSCH reception processing time: After the UE receives the DCI that schedules the PDSCH, it will receive the PDSCH in the time slot indicated by the DCI, and determine the feedback of the hybrid automatic repeat request-acknowledgement corresponding to the PDSCH according to K1. , HARQ-ACK) physical uplink control channel (physical uplink control channel, PUCCH) time slot, where K1 is according to the downlink DCI included in the PDSCH and HARQ feedback timing indicator (PDSCH-to-HARQ feedback timing indicator) or The number of timeslot offsets between PUCCH and PDSCH for HARQ-ACK feedback obtained by the higher layer parameter (dl-Data To UL-ACK). If the first uplink OFDM symbol of the PUCCH on which the UE sends HARQ-ACK is not earlier than the OFDM symbol L 1 , L 1 is defined as T proc,1 after the last OFDM symbol of the PDSCH of the transmission TB, and the UE reports a valid HARQ- ACK.
反馈HARQ-ACK的PUCCH确定方式：基站可以通过无线资源控制(radio resource control，RRC)信令为每个UE配置一个或多个(最多4个)PUCCH资源集(PUCCH resource set)，RRC配置或预定义每个资源集(RESET)可以承载的UCI载荷的最大比特数(例如第一个RESET最多2bit，第二、第三个RESET为N1、N2，第四个RESET最多为1706bit，N1、N2由RRC配置),每个RESET内可以包含多个PUCCH资源(第一个RESET内最多有32个PUCCH，其他RESET每个最多包含8个PUCCH)。在UE侧，UE接收到PDSCH后需要反馈HARQ-ACK，为了确定反馈HARQ-ACK所在PUCCH，UE需要先通过调度PDSCH的物理下行控制信道(physical downlink control channel，PDCCH)中的K1确定PUCCH所在时隙(slot)；然后通过需要反馈的HARQ-ACK的比特数确定PUCCH所在RESET；在所确定的RESET内，根据PDCCH的PUCCH资源指示(PUCCH resource indicator，PRI)域(RESET内所含PUCCH不超过8个时)或PRI与PDCCH第一个控制信道单元(control channel element，CCE)索引(first CCE index)确定具体是RESET内的哪一个PUCCH(RESET内所含PUCCH超过8个时)。当在一个时隙内反馈多个PDSCH的HARQ-ACK时，UE根据调度这些PDSCH的最后一个DCI(last DCI)中的PRI或PRI与第一个CCE索引确定PUCCH。The PUCCH feedback HARQ-ACK determination method: the base station can configure one or more (up to 4) PUCCH resource sets (PUCCH resource sets) for each UE through radio resource control (radio resource control, RRC) signaling, RRC configuration or Predefine the maximum number of UCI payload bits that each resource set (RESET) can carry (for example, the first RESET is up to 2 bits, the second and third RESETs are N1, N2, and the fourth RESET is up to 1706 bits, N1, N2 Configured by RRC), each RESET can contain multiple PUCCH resources (the first RESET has a maximum of 32 PUCCHs, and the other RESETs each contain a maximum of 8 PUCCHs). On the UE side, the UE needs to feed back HARQ-ACK after receiving the PDSCH. In order to determine the PUCCH where the HARQ-ACK is fed back, the UE needs to first determine when the PUCCH is located through K1 in the physical downlink control channel (PDCCH) that schedules the PDSCH. Slot; then the RESET of the PUCCH is determined by the number of HARQ-ACK bits that need to be fed back; within the determined RESET, according to the PUCCH resource indicator (PRI) field of the PDCCH (the PUCCH contained in the RESET does not exceed 8 hours) or the first control channel element (CCE) index (first CCE) of the PRI and PDCCH to determine which PUCCH in the RESET (when the PUCCH contained in the RESET exceeds 8). When feeding back HARQ-ACKs of multiple PDSCHs in one time slot, the UE determines the PUCCH according to the PRI or PRI in the last DCI (last DCI) that schedules these PDSCHs and the first CCE index.
单TRP的HARQ-ACK码本：支持两种类型的HARQ-ACK码本，即半静态HARQ-ACK码本(semi-static HARQ-ACK codebook)和动态HARQ-ACK码本(dynamic HARQ-ACK codebook)。其中，对于半静态HARQ-ACK码本，UE可以根据RRC配置的候选PDSCH接收机会(candidate PDSCH reception occasion)、PDSCH的时域资源分配(PDSCH-time domain resource allocation)、PDSCH到HARQ-ACK的反馈定时(dl-Data To UL-ACK或PDSCH-to HARQ-timing)等参数确定某个时隙可能反馈的所有PDSCH确定HARQ-ACK码本，由于可能包含对实际调度的和未调度的PDSCH的HARQ，其码本一般会较大。对于动态HARQ-ACK码本，UE可以根据实际调度的PDSCH确定HARQ-ACK码本，由于只对实际调度的PDSCH进行反馈，因此其HARQ-ACK的码本大小通常会小于半静态HARQ-ACK码本的码本大小。UE具体使用哪个类型的码本，是通过RRC配置确定的。采用动态HARQ-ACK码本时，为了防止由于UE未能正确检测出调度的PDCCH而导致的 收发方各自认为的HARQ-ACK比特数不一致的情况，基站在DCI中包含下行分配索引(downlink assignment index，DAI)；DAI又可分为两部分，即计数器DAI(counter DAI)和总数DAI(total DAI)。计数器DAI用于指示截止到该DCI调度下行传输的数量，而总数DAI则指示截止到该DCI所有载波的下行传输的总数。Single TRP HARQ-ACK codebook: supports two types of HARQ-ACK codebooks, namely semi-static HARQ-ACK codebook (semi-static HARQ-ACK codebook) and dynamic HARQ-ACK codebook (dynamic HARQ-ACK codebook) ). Among them, for the semi-static HARQ-ACK codebook, the UE can configure the candidate PDSCH receiver meeting (candidate PDSCH reception occasion), PDSCH time domain resource allocation (PDSCH-time domain resource allocation), and feedback from PDSCH to HARQ-ACK configured by RRC. Timing (dl-Data To UL-ACK or PDSCH-to HARQ-timing) and other parameters determine all PDSCHs that may be fed back in a time slot determine HARQ-ACK codebook, because it may contain HARQ for actually scheduled and unscheduled PDSCHs , The codebook is generally larger. For the dynamic HARQ-ACK codebook, the UE can determine the HARQ-ACK codebook according to the actually scheduled PDSCH. Since only the actually scheduled PDSCH is fed back, the size of the HARQ-ACK codebook is usually smaller than the semi-static HARQ-ACK code The codebook size of the book. The specific type of codebook used by the UE is determined by the RRC configuration. When the dynamic HARQ-ACK codebook is used, in order to prevent the inconsistency of the number of HARQ-ACK bits considered by the sender and receiver due to the failure of the UE to correctly detect the scheduled PDCCH, the base station includes a downlink assignment index in the DCI. ,DAI); DAI can be divided into two parts, namely counter DAI (counter DAI) and total DAI (total DAI). The counter DAI is used to indicate the number of downlink transmissions scheduled to the DCI, and the total DAI indicates the total number of downlink transmissions to all carriers of the DCI.
多TRP的多PDSCH的HARQ-ACK反馈支持两种方案：The HARQ-ACK feedback of multiple TRPs and multiple PDSCHs supports two schemes:
方案1、一个PUCCH反馈多个TRP的PDSCH对应的HARQ-ACK信息，即联合HARQ-ACK反馈(joint HARQ-ACK feedback)。 Solution 1. One PUCCH feeds back HARQ-ACK information corresponding to the PDSCHs of multiple TRPs, that is, joint HARQ-ACK feedback (joint HARQ-ACK feedback).
方案2、多个PUCCH反馈多个TRP的PDSCH对应的HARQ-ACK信息，一个PUCCH反馈一个TRP的PDSCH对应的HARQ-ACK信息，即分离HARQ-ACK反馈(separate HARQ-ACK feedback)。Solution 2: Multiple PUCCHs feed back HARQ-ACK information corresponding to PDSCHs of multiple TRPs, and one PUCCH feeds back HARQ-ACK information corresponding to PDSCHs of one TRP, that is, separate HARQ-ACK feedback.
本申请实施例提供一种DCI调度方法、设备及***，UE可以接收网络设备发送的K个DCI和满足预设条件的K个PDSCH重复，并在第一PUCCH上反馈K个PDSCH重复的第一HARQ-ACK信息。由于UE可以根据多个DCI接收多个PDSCH重复，即采用多个DCI调度PDSCH的多个重复传输，因此可以增加DCI调度的灵活性，从而可以提高UE传输过程中指示的资源的准确性。The embodiments of the application provide a DCI scheduling method, device, and system. The UE can receive K DCIs sent by a network device and K PDSCH repetitions meeting preset conditions, and feed back the first of the K PDSCH repetitions on the first PUCCH. HARQ-ACK information. Since the UE can receive multiple PDSCH repetitions according to multiple DCIs, that is, multiple DCIs are used to schedule multiple repeated transmissions of the PDSCH, the flexibility of DCI scheduling can be increased, and the accuracy of the resources indicated in the UE transmission process can be improved.

可以理解，UE可以根据传输第一HARQ-ACK之前满足时序要求的调度的最后一个PDSCH重复的DCI来确定第一PUCCH(可能属于任意配置标识的CORESET)；或者UE可以根据传输第一HARQ-ACK之前在预定配置标识的CORESET上发送的最后一个PDSCH重复的DCI来确定第一PUCCH。It is understandable that the UE may determine the first PUCCH (which may belong to the CORESET of any configuration identifier) according to the DCI of the last PDSCH scheduled to meet the timing requirements before transmitting the first HARQ-ACK; or the UE may transmit the first HARQ-ACK according to the The DCI of the last PDSCH repeated previously sent on the CORESET identified by the predetermined configuration is used to determine the first PUCCH.

可以理解，在确定为关联到不同配置标识的CORESET所包含的DCI指示的反馈HARQ-ACK信息的PUCCH相同(或存在交叠)，或者在联合HARQ-ACK反馈的情况下，若UE不支持对K个PDSCH重复进行软合并，则UE可以在联合HARQ-ACK码本内分别将多个PDSCH重复的HARQ-ACK信息进行反馈，或者反馈一个HARQ-ACK信息，其值为多个对应的HARQ-ACK比特求或；若UE支持对K个PDSCH重复进行软合并，则UE可以在联合HARQ-ACK码本内分别对多个PDSCH重复的HARQ-ACK比特进行反馈，每个反馈都是自身(前面无PDSCH重复时)或与之前PDSCH重复的软合并之后得到的一个HARQ-ACK信息，或者反馈一个HARQ-ACK信息，其值为K个PDSCH重复软合并后的HARQ-ACK信息。It can be understood that when it is determined that the PUCCHs for feeding back HARQ-ACK information indicated by the DCI contained in CORESETs associated with different configuration identifiers are the same (or overlap), or in the case of joint HARQ-ACK feedback, if the UE does not support the If K PDSCHs are repeatedly subjected to soft combining, the UE can respectively feed back the HARQ-ACK information of multiple PDSCHs in the joint HARQ-ACK codebook, or feed back one HARQ-ACK information, the value of which is multiple corresponding HARQ-ACK information. ACK bits are ORed; if the UE supports soft combining of K PDSCH repetitions, the UE can feed back the HARQ-ACK bits of multiple PDSCH repetitions in the joint HARQ-ACK codebook. Each feedback is its own (before When there is no PDSCH repetition) or one HARQ-ACK information obtained after soft merging with the previous PDSCH repetition, or one HARQ-ACK information is fed back, the value of which is the HARQ-ACK information after the repeated soft merging of K PDSCHs.
示例性的，下面结合附图7、附图8和附图9对反馈HARQ-ACK信息的PUCCH进行示例性的说明。假设UE接收了K＝4个DCI调度的4个PDSCH重复，其中DCIi调度PDSCHi，i＝1,2,3,4，阴影区域的DCI表示其所在的CORESET关联到配置标识1，非阴影区域的DCI表示其所在的CORESET关联到配置标识2，即L＝2。以下描述中如果没有明确指出则均假设PUCCH1满足PDSCH1、PDSCH2、PDSCH3、PDSCH4的时序(timeline)要求，以及PUCCH2满足PDSCH1、PDSCH2、PDSCH3、PDSCH4的时序要求(例如PDSCHi的最后一个符号到PUCCHj的第一个符号之间的符号数大于等于特定的时间阈值，则PUCCHj满足PDSCHi的时序要求，UE反馈有效的HARQ-ACK信息；否则PUCCHj不满足PDSCHi的时序要求)。Exemplarily, the PUCCH that feeds back HARQ-ACK information will be exemplarily described below with reference to FIG. 7, FIG. 8, and FIG. 9. Suppose that the UE receives 4 PDSCH repetitions scheduled by K=4 DCIs, where DCIi schedules PDSCHi, i=1,2,3,4, the DCI in the shaded area indicates that the CORESET where it is located is associated with configuration identifier 1, and the DCI indicates that the CORESET where it is located is associated with configuration identification 2, that is, L=2. If not explicitly stated in the following description, it is assumed that PUCCH1 meets the timing requirements of PDSCH1, PDSCH2, PDSCH3, and PDSCH4, and PUCCH2 meets the timing requirements of PDSCH1, PDSCH2, PDSCH3, and PDSCH4 (for example, the last symbol of PDSCHi to the first symbol of PUCCHj) If the number of symbols between one symbol is greater than or equal to a specific time threshold, PUCCHj meets the timing requirements of PDSCHi, and the UE feeds back valid HARQ-ACK information; otherwise, PUCCHj does not meet the timing requirements of PDSCHi).
其中，HARQ-ACK(i)表示一个HARQ-ACK信息，为PDSCHi的HARQ-ACK信息。HARQ-ACK(i1,i2,…ik)表示k个HARQ-ACK信息，分别为PDSCHi1的HARQ-ACK信息、PDSCHi2的HARQ-ACK信息、……、PDSCHik的HARQ-ACK信息。HARQ-ACK(i1|i2|…|ik)表示一个HARQ-ACK信息，为PDSCHi1、PDSCHi2、……、PDSCHik分别得到的HARQ-ACK信息对应比特求或。HARQ-ACK(i1+i2+…+ik)表示一个HARQ-ACK信息，为 PDSCHi1、PDSCHi2……PDSCHik软合并得到的HARQ-ACK信息。Among them, HARQ-ACK(i) represents a piece of HARQ-ACK information, which is HARQ-ACK information of PDSCHi. HARQ-ACK (i1, i2,...ik) represents k pieces of HARQ-ACK information, which are respectively the HARQ-ACK information of PDSCHi1, the HARQ-ACK information of PDSCHi2,..., the HARQ-ACK information of PDSCHik. HARQ-ACK (i1|i2|...|ik) represents a piece of HARQ-ACK information, which is the OR of the HARQ-ACK information obtained by PDSCHi1, PDSCHi2,..., PDSCHik respectively. HARQ-ACK (i1+i2+...+ik) represents a piece of HARQ-ACK information, which is the HARQ-ACK information obtained by soft combination of PDSCHi1, PDSCHi2...PDSCHik.
反馈HARQ-ACK信息的几种情况如下：Several situations for feeding back HARQ-ACK information are as follows:

The UE can determine to feed back their HARQ-ACK information on PUCCH1 and PUCCH2 in time slot n+m according to the respective DCI indications contained in the CORESET with the same configuration identifier, and PUCCH1 and PUCCH2 do not overlap, or are independent HARQ-ACK feedback .

若每个PDSCH重复反馈一个HARQ-ACK信息，则在PUCCH1上反馈HARQ-ACK(1,3)，在PUCCH2上反馈HARQ-ACK(2,4)。If each PDSCH repeatedly feeds back one HARQ-ACK information, then HARQ-ACK(1,3) is fed back on PUCCH1, and HARQ-ACK(2,4) is fed back on PUCCH2.
若多个PDSCH重复反馈一个HARQ-ACK信息，假设根据预定规则确定反馈该HARQ-ACK的PUCCH为根据DCI4确定的PUCCH2，则在PUCCH2上反馈一个HARQ-ACK信息——HARQ-ACK(1|2|3|4)。If multiple PDSCHs repeatedly feed back one HARQ-ACK message, assuming that the PUCCH that feeds back the HARQ-ACK is determined according to the predetermined rule to be the PUCCH2 determined according to DCI4, then a HARQ-ACK message is fed back on PUCCH2——HARQ-ACK(1|2 |3|4).
若多个PDSCH重复反馈L＝2个HARQ-ACK信息，假设PUCCH1、PUCCH2均满足PDSCH1、PDSCH2、PDSCH3、PDSCH4的时序要求，则在PUCCH1上反馈一个HARQ-ACK信息，在PUCCH2上反馈一个HARQ-ACK信息。这两个HARQ-ACK信息均为HARQ-ACK(1|2|3|4)。假设PUCCH1满足PDSCH1、PDSCH2、PDSCH3的时序要求而不满足PDSCH4的时序要求，则PUCCH1上反馈接收PDSCH3后的HARQ-ACK信息——HARQ-ACK(1|2|3)；假设PUCCH2满足PDSCH1、PDSCH2、PDSCH3、PDSCH4的时序要求，则PUCCH2上反馈接收PDSCH4后的HARQ-ACK信息——HARQ-ACK(1|2|3|4)。If multiple PDSCHs repeatedly feed back L=2 HARQ-ACK messages, assuming that PUCCH1 and PUCCH2 all meet the timing requirements of PDSCH1, PDSCH2, PDSCH3, and PDSCH4, then one HARQ-ACK message is fed back on PUCCH1, and one HARQ-ACK message is fed back on PUCCH2. ACK information. The two HARQ-ACK information are both HARQ-ACK (1|2|3|4). Assuming that PUCCH1 meets the timing requirements of PDSCH1, PDSCH2, and PDSCH3 but not PDSCH4, then the HARQ-ACK information after receiving PDSCH3 is fed back on PUCCH1—HARQ-ACK(1|2|3); assuming PUCCH2 meets PDSCH1, PDSCH2 , PDSCH3, PDSCH4 timing requirements, then PUCCH2 feedbacks the HARQ-ACK information after receiving PDSCH4-HARQ-ACK(1|2|3|4).

若多个PDSCH重复反馈L＝2个HARQ-ACK信息，则在PUCCH1上反馈一个HARQ-ACK信息，在PUCCH2上反馈一个HARQ-ACK信息。假设PUCCH1满足PDSCH1、PDSCH2、PDSCH3的时序要求而不满足PDSCH4的时序要求，则PUCCH1上反馈接收PDSCH3后的HARQ-ACK信息——HARQ-ACK(1+2+3)；假设PUCCH2满足PDSCH1、PDSCH2、PDSCH3、PDSCH4的时序要求，则PUCCH2上反馈接收PDSCH4后的HARQ-ACK信息——HARQ-ACK(1+2+3+4)。If multiple PDSCHs repeatedly feed back L=2 HARQ-ACK information, then one HARQ-ACK information is fed back on PUCCH1, and one HARQ-ACK information is fed back on PUCCH2. Assuming that PUCCH1 meets the timing requirements of PDSCH1, PDSCH2, and PDSCH3 but not PDSCH4, then the HARQ-ACK information after receiving PDSCH3 is fed back on PUCCH1—HARQ-ACK(1+2+3); assuming PUCCH2 meets PDSCH1, PDSCH2 , PDSCH3, PDSCH4 timing requirements, then PUCCH2 feedback the HARQ-ACK information after receiving PDSCH4-HARQ-ACK (1+2+3+4).
